i-ductile iron material butterfly valve

I-Victaulic OEM kanye nePhini Likamongameli Wezinkonzo Zasolwandle u-Didier Vassal baqhathanisa izindlela zokuhlanganisa amapayipi ane-flange ne-grooved futhi wachaza izinzuzo zokuhlanganisa amapayipi asele phezu kwama-flange. Izinhlelo zamapayipi ezisebenza kahle zibalulekile ezinhlobonhlobo zezinsizakalo ezidingekayo emikhunjini, okuhlanganisa nezinhlelo zesibili ezifana nezinhlelo ze-bilge ne-ballast, ukupholisa ulwandle namanzi ahlanzekile, uwoyela wokugcoba, ukuvikela umlilo nokuhlanza amadekhi. Kulezi zinhlelo, lapho izinga lepayipi livumela, enye indlela ephumelelayo yokuxhuma ipayipi esikhundleni sokushisela/i-flanging ukusetshenziswa kwamajoyinti emishini afakiwe, ahlinzeka ngochungechunge lwezinzuzo zobuchwepheshe, ezomnotho kanye nezingokoqobo. Lokhu kubandakanya ukusebenza okuthuthukisiwe; ukufakwa nokugcinwa okusheshayo nokulula kanye nokunciphisa isisindo ebhodini. Izinkinga zokusebenza Emajoyini amapayipi ane-flanged, ama-flange amabili okukhwelana ahlanganiswe ndawonye futhi i-gasket iyacindezelwa ukwenza uphawu. Njengoba amabhawodi namantongomane ejoyinti le-flange emunca futhi enxephezela amandla esistimu, ngokuhamba kwesikhathi, amabhawodi namantongomane azokwelula futhi alahlekelwe ukuqina kwawo kwasekuqaleni ngenxa yokuguquguquka kwengcindezi, ingcindezi yokusebenza kwesistimu, ukudlidliza, nokwanda nokufinyela okushisayo. Lapho la mabhawodi ethola ukuphumula kwe-torque, i-gasket izolahlekelwa uphawu lwayo lokucindezela, okungaholela emazingeni ahlukene okuvuza. Ngokuya ngendawo kanye nomsebenzi wohlelo lwamapayipi, ukuvuza kungabiza futhi kube yingozi, okuholela ekunakekeleni/ekulungiseni isikhathi sokuphumula kanye nezingozi. I-gasket idinga ukushintshwa lapho uhlakaza ukuhlanganyela, ngoba ngokuhamba kwesikhathi, i-gasket izonamathela ebusweni be-flange. Lapho uqaqa ukuhlanganisa, ama-gaskets adinga ukukhunyulwa ezindaweni ezimbili ze-flange, futhi lezi zindawo zidinga ukuhlanzwa ngaphambi kokufaka ama-gaskets, futhi kwandise isikhathi sokulungisa. Ngenxa yamandla okuxhuma umshudo kanye nokwandiswa nokufinyela kwesistimu, i-flange gasket izophinde ikhiqize ukucindezelwa "i-deformation" ngokuhamba kwesikhathi, okungenye imbangela yokuvuza. Idizayini yamapayipi emishini ehlanganisiwe inqoba lezi zinkinga zokusebenza. Okokuqala, i-groove yenziwa ekugcineni kwepayipi, futhi uxhumano lwepayipi lulungiswa ngokuhlanganyela, futhi i-elastomer gasket esabelayo, ephendula ukucindezela ifakwe ekuhlanganyeleni. Izindlu zokuhlanganisa zizungeza ngokuphelele i-gasket, iqinisa uphawu futhi ibambe endaweni yayo, ngoba ukuhlanganisa kuhlanganisa futhi kwakha i-interlock ethembekile emgodini wepayipi. Ubuchwepheshe bamuva bokuhlanganisa buvumela amapayipi afinyelela kuma-intshi angu-24 (600 mm) ububanzi ukuba ahlanganiswe ngokugcwele ngamantongomane namabhawodi amabili ukuze avikele amalunga azibambayo. Ngenxa yobudlelwano bokuklama phakathi kwamapayipi, ama-gaskets, nezindlu, amalunga emishini akha uphawu oluphindwe kathathu. Lobu budlelwano buzoqiniswa lapho uhlelo lucindezelwa. Amalunga aqinile futhi avumelana nezimo atholakala ngezindlela ezimbili: aqinile futhi aguquguqukayo. Amajoyinti epayipi emishini ka-Groove adlulise isitifiketi sohlobo lomphakathi ngezigaba futhi angashintsha izindlela zokuxhuma zokushisela/i-flange kumasistimu angu-30, kuye ngezindinganiso zokufakwa ezibekwe yinhlangano ngayinye yezitifiketi. Isibonelo, sebenzisa ama-couplings aqinile ezindaweni ezinjengama-multifolds nama-valve, lapho kulula ukufinyelela khona futhi ashintshe kunama-flange. Ngenxa yemvelo yokwakheka kwayo, ukuhlangana okuqinile nakho kuhlinzeka ngokuqina kwe-axial kanye ne-radial okuqhathaniswa nama-flange noma amalunga ashiselwe. Ngaphezu kokunyakaza kwamapayipi okubangelwa ukwanda okushisayo noma ukudlidliza, amalunga aguquguqukayo anezinzuzo ezinhlelweni zokusebenza lapho ukunyakaza okuhlobene phakathi kwepayipi nesakhiwo esisekelayo kulindeleke. Ukwandiswa nokufinyela kubeka ingcindezi kuma-flange namapayipi, okuthi ngokuhamba kwesikhathi kungalimaza i-gasket. Uma lokhu kwenzeka, kuba nengozi yokuvuza emalungeni. Ukuhlanganisa okuguquguqukayo kohlobo lwe-groove kungakwazi ukuzivumelanisa nokugudluzwa kwamapayipi ngendlela yokunyakaza kwe-axial noma ukuchezuka kwe-angular. Ngenxa yalesi sizathu, afaneleka kakhulu ukufaka amapayipi amade, ikakhulukazi phakathi kwamabhulokhi. Ulwandle oluphakeme lungabangela ukuba ama-flange axege ngokuhamba kwesikhathi, okuholela engcupheni yokuvuza nokuhlukaniswa kwamapayipi. Ukuhlangana okuqinile nokuguquguqukayo nakho kunezinzuzo zokunciphisa umsindo nokunciphisa ukudlidliza, ngaphandle kwesidingo sezingxenye ezikhethekile zokunciphisa umsindo nezinsimbi zenjoloba ezibolayo noma izinto ezifanayo. Ukusetshenziswa kwemishini yamapayipi afakwe amapayipi kungasheshisa futhi kwenze kube lula ukufaka nokunakekela, futhi kuthuthukise ukusebenza kahle kwesistimu yamapayipi omkhumbi. Kulula ukufaka Uma ufaka okokuqala, izimbobo ze-bolt ze-flange kufanele ziqondaniswe ngokunembile, bese ziqiniswa ukuze kulungiswe ukujoyina. Izinkomba zembobo ye-bolt endaweni yokungena kanye ne-outlet kumele futhi ihambisane ngokuphelele nama-flanges kumapayipi azoxhunywa kumishini. Njengoba inani lezimbobo ku-flange linquma indawo eyodwa kweziningi ezigxilile, i-fitting kuphela noma i-valve engazungeziswa ukuze ifane nezimbobo zebhawodi. Ngaphezu kwalokho, omunye umkhawulo wepayipi le-flange kufanele futhi uhambisane ne-mating flange yayo, okwandisa nakakhulu ubunzima bokuhlangana kanye nengozi yokungahambi kahle. Isistimu yamapayipi e-grooved ayinayo le nkinga, futhi ukufakwa kulula kakhulu. Amapayipi kanye nezingxenye zokukhwelana zingazungeziswa ngokuphelele ngamadigri angama-360. Ayikho iphethini yembobo yebhawodi ezoqondaniswa, futhi ukuhlanganisa kungabekwa noma yikuphi eduze kwelunga. I-coupling ingazungeziswa eduze kwepayipi ukuze kufinyeleleke kalula kumabhawodi kanye nokufinyelela okulula kumishini. Ngaphezu kokuqeda ukungaboni ngaso linye phakathi nokufakwa, umsebenzi wokuma kwe-360-degree wokuhlanganisa kanye nephrofayili yakhona encane uma kuqhathaniswa nama-flange kwenza ukufakwa kwesistimu ye-groove ifaneleke kakhulu ezindaweni ezincane. Ngaphezu kwalokho, isifaki singabeka wonke amabhawodi omhlangano endaweni eyodwa endaweni efanayo ukuze kube lula ukuhlolwa nokugcinwa kwesistimu. Ama-flange acishe abe kabili ububanzi bangaphandle bepayipi axhunywe kuwo. Ngokwesilinganiso, amajoyinti anama-grooved ayingxenye kuphela yalo sayizi. Inzuzo yosayizi yedizayini encane yenza isistimu yegroove ifaneleke ekusebenzeni okubambezeleke isikhala, okufana nedekhi kanye nokungena odongeni-iqiniso elaqashelwa kudala ngawo-1930s, lapho amalunga e-Victaulic aqala ukusetshenziswa ezindaweni zemikhumbi zaseBrithani. Isivinini sokuhlanganisa Ngenxa yokuthi ukuhlanganisa kunamabhawodi ambalwa futhi akunayo imfuneko yetorque efika ku-12” (300mm), amapayipi afakwe imigexo angafakwa ngokushesha kakhulu kunama-flange. Ngokungafani nama-flange okumelwe ashiselwe emaphethelweni epayipi, imihlangano ye-valve eyi-grooved Ayikho i-welding edingekayo, okuqhubeka kunciphisa isikhathi sokufaka futhi kuqede umonakalo ongase ube khona oshisayo ku-valve, kuyilapho kunciphisa izingozi zokuphepha ngokuqeda ukucubungula okushisayo. Ukuqhathaniswa kolayini we-DIN 150 we-ballast ofakwe nemikhiqizo ye-Victaulic grooved nezindlela zokuxhuma zendabuko Kubonisa ukuthi isikhathi esiphelele sokufakwa esidingekayo sehliswe ngo-66% (amahora angu-150.47 namahora omuntu angu-443.16). Uma kuqhathaniswa nama-couplings aqinile angu-60, isikhathi esidingekayo sokufaka ama-sleeve flange angu-52 nezindololwane ezishiselwe kanye nezinsika sibonisa Umehluko omkhulu wesikhathi. Ukuhlanganisa kudinga amabhawodi amabili kuphela, futhi ububanzi bepayipi bungafinyelela amasentimitha angu-24 (600 mm). Ngokuphambene, kububanzi obukhulu besayizi, i-flange idinga okungenani amasethi angu-20 amantongomane namabhawodi. Ngaphezu kwalokho, indlela i-Lan idinga ukusebenzisa ama-wrenches akhethekile okuqinisa iphethini yenkanyezi edla isikhathi ukuze kukale futhi kuqinisekiswe ukuthi imininingwane yetorque efanele iyafinyelelwa. Ubuchwepheshe beshubhu eligobile buvumela ukusetshenziswa kwamathuluzi ezandla ajwayelekile ukuze kuhlanganiswe ukuhlanganisa, uma amaphedi okukhwelana endlu ehlanganisayo ehlangana nepheya yensimbi Ukufakwa kungafakwa ngendlela efanele uma kudingwa ngensimbi. Ukuhlola okubonakalayo okulula kungaqinisekisa ukuhlangana okulungile. Ngakolunye uhlangothi, ama-flange awanikezi isiqinisekiso esibonakalayo: okuwukuphela kwendlela yokuqinisekisa ukuhlangana okulungile ukugcwalisa nokucindezela uhlelo, ukuhlola ukuvuza nokwakha kabusha njengoba kudingeka Qinisa amalunga. Isici esifanayo sesistimu yamapayipi agxilile ukuthi isheshisa ukufakwa-amabhawodi ambalwa futhi azikho izidingo zetorque-futhi yenza ukugcinwa kwesistimu noma ukuguqulwa kube umsebenzi osheshayo nolula. Isibonelo, ukuze uthole amaphampu noma ama-valve, khulula amabhawodi amabili okuhlanganisa, bese ukhipha indlu kanye ne-gasket ekuhlanganyeleni. Kuhlelo lwe-flange, amabhawodi amaningi adinga ukususwa. Lapho uhlanganisa kabusha i-flange, ukufakwa kokuqala okufanayo okudla isikhathi kuyadingeka. Ukulandelana kokuqinisa ibhawodi. Ngenxa yokuthi akudingeki ukuthi ziqiniswe kabusha, ama-couplings aqeda ukunakekelwa kwansuku zonke okuhlobene nama-flange. Ngokungafani nama-flange asebenzisa ukucindezeleka okuguquguqukayo kumawasha, amantongomane, nama-bolts, ama-couplings ashintsha amawasha kusukela ekucindezelweni Okunembile kwangaphandle kokuhlangene kwepayipi. Ngaphezu kwalokho, ngenxa yokuthi i-gasket yokuhlanganisa ayithinteki ngamandla amakhulu okucindezela, ayidingi ukushintshwa njalo, kuyilapho i-gasket ye-flange idinga ukushintshwa ngesikhathi sokuhlukaniswa kwesistimu nokugcinwa. Ukuze kwehliswe umsindo wesistimu nokudlidliza, isistimu ye-flange Idinga ukuvuthela kwerabha noma amapayipi aguquguqukayo aboshwe. Lezi zingxenye zingase zehluleke ngenxa yokwelula ngokweqile, futhi ngaphansi kokuguga nokuklebhuka okuvamile, zidinga ukushintshwa njalo ngemva kweminyaka eyi-10 ngokwesilinganiso, okuholela ezindlekweni nesikhathi sokungasebenzi kwesistimu. Nokho, mechanical grooved amapayipi Amalunga angandisa impilo yesistimu. Ikhono labo lokuzivumelanisa nokudlidliza kwesistimu linciphisa ingozi yokwehluleka ngokuhlanganyela ngaphandle kwesidingo semikhiqizo ekhethekile edinga ukugcinwa okuvamile noma ukushintshwa. Amawasha asentwasahlobo anwebekayo afakwe kuma-couplings aguquguqukayo futhi aqinile ahlala isikhathi eside futhi angamelana nokukhulu Ingcindezi yokusebenza nomthwalo wama-cyclic. Uhlelo lungacindezelwa ngokuphindaphindiwe futhi lucindezelwe ngaphandle kokukhathala kwe-elastomer gasket. Umhlangano we-valve wokunciphisa isisindo uvame ukuhlanganisa izingxenye ze-flange. Nokho, le ndlela yokuxhuma izokwengeza okungadingekile ohlelweni lwamapayipi Isisindo. Ivalvu ye-flange engamayintshi angu-6 (150 mm) iqukethe i-lug butterfly valve Yakhiwe, ixhunywe ku-flange yentamo eshiselwe, enamabhawudi ayisishiyagalombili namantongomane ohlangothini ngalunye lwevalvu, enesisindo esingamakhilogremu angama-85. I-valve engu-6-intshi (150 mm) isebenzisa ivalve yevemvane esekugcineni eyi-grooved, ipayipi lokugcina eligobile, nama-coupling amabili aqinile ukuze kuxhunywe umhlangano. Inesisindo esingamakhilogremu angu-35, okuyisisindo esingaphansi ngo-58% kunomhlangano we-flange. Ngakho-ke, umhlangano we-valve oyi-grooved uyindawo ekahle yomkhakha wokwakha umkhumbi. Ukuqhathaniswa kwamapayipi e-DIN 150 e-ballast afakwe ngenhla kubonisa ukuthi uma kusetshenziswa imikhiqizo ye-Victaulic grooved esikhundleni sendlela yokuxhumana evamile, isisindo sincishiswa ngo-30% (2,164 lbs vs. 3,115 lbs). Uma kuqhathaniswa nama-couplings aqinile angu-60, ama-sleeve flange angu-52, amasethi ebhawodi namawasha kubangela ukwanda kwesisindo sesistimu yokushisela/i-flange. Ukusetshenziswa kwamapayipi e-grooved amapayipi esikhundleni se-flanges kunganciphisa isisindo futhi kufanelekile amapayipi anobukhulu obuhlukahlukene. Ubukhulu bokunciphisa buxhomeke kububanzi bepayipi kanye nohlobo lwamalungu asetshenzisiwe. Esivivinyweni kusetshenziswa i-Victaulic 77 coupling (ukuhlanganisa okunzima kakhulu ochungechungeni) ukuze kuxhunywe ipayipi, isisindo esiphelele sokufakwa sengxenye egobile sasiphansi kakhulu kunaleso semikhono emikhono emibili engasindi ye-PN10. Ukuncipha kwesisindo kubhalwe kanje: 4” (100mm) – 67%; 12” (300mm) – 54%; 20 amayintshi (500 mm) – 60.5%. Ukusetshenziswa kohlobo olulula oluvumelana nezimo 75 noma uhlobo oluqinile lwe-07 ama-couplings kanye/noma izinhlobo ze-flange ezisindayo kungathola kalula ukwehlisa isisindo esingu-70%. Isibonelo, isethi ye-flange engu-24-intshi (600 mm) esetshenziswa ohlelweni lwe-TG2 inesisindo esingamaphawundi angu-507, kodwa izingxenye ezifanayo ezisebenzisa ukufakwa kwe-Victaulic zinesisindo esingamaphawundi angu-88 kuphela. Imikhumbi yemikhumbi esebenzisa ngokukhethekile ukuhlanganisa ama-grooved esikhundleni sama-flange ezinhlelweni ezikhethiwe ibhale ukuthi imikhumbi yokwesekwa yaphesheya kwezilwandle yehlise isisindo ngamathani ayi-12 futhi imikhumbi yemikhumbi yehlise isisindo ngamathani angama-44. Izinzuzo zezomnotho ezilethwa ubuchwepheshe bemikhumbi kubanikazi bemikhumbi zisobala: isisindo esincane sisho imithwalo eminingi noma abagibeli kanye nokusetshenziswa kancane kukaphethiloli. Kwenza futhi ukuphatha uhlelo lwamapayipi omkhumbi kube lula. Ithrendi yokuthuthuka Ngenxa yesivinini sokufakwa okusheshayo, ukugcinwa okuqinile nesisindo esincane, amasistimu wamapayipi omkhombe angahlinzeka ngezinzuzo ezibaluleke kakhulu kunemikhiqizo efanayo ye-flange. Lezi zici, ezihambisana nezinzuzo ezengeziwe ezifana nokuthembeka, ukuqondanisa kalula kanye nezingozi eziphansi zokuphepha, zenze abanikazi bemikhumbi, onjiniyela nezindawo zemikhumbi ukuthi bakhethe amasistimu emishini asemigwaqweni esikhundleni sama-flange. Lo mkhuba okhulayo wokusebenzisa ubuchwepheshe obuyi-grooved usekelwa abahlinzeki bemishini efana nezishintshisi zokushisa, ama-box cooler nama-coolers, kanye nabakhiqizi be-valve kanye ne-compressor, abaningi babo manje abahlinzeka ngemikhiqizo enokuxhumeka kokuphela oku-grooved. Ububanzi bezinsizakalo ezingasebenzisa izihlanganisi zamapayipi ane-grooved bukhula kancane kancane. Ikwakhela ekusetshenzisweni kwayo ngempumelelo ezinhlelweni zamanzi, i-Victaulic iqhubeka nomlando wayo omude wokuqamba izinto ezintsha ukuze kuthuthukiswe ama-gasket angashi kanye nokuthola imvume yohlobo lwezinsizakalo zikaphethiloli zaphesheya kwezilwandle.
