ivalve uvemvane we-pneumatic actuated

U-Didier Vassal, iPhini Likamongameli we-Victaulic OEM kanye Nezinsizakalo Zasolwandle, uqhathanise izindlela zokuxhunywa kwamapayipi ane-flanged ne-grooved futhi wachaza izinzuzo ezihlinzekwa ngamajoyinti amapayipi angaphezu kwama-flange. Izinhlelo zamapayipi ezisebenzayo zibalulekile ezinhlobonhlobo zezinsizakalo ezidingekayo emikhunjini, okuhlanganisa izinhlelo ezisizayo ezifana nezinhlelo ze-bilge ne-ballast, ukupholisa amanzi olwandle namanzi ahlanzekile, uwoyela wokugcoba, ukuvikela umlilo kanye nokuhlanza ideski. Kulawa masistimu avunyelwe yibanga lamapayipi, enye indlela ephumelelayo yokusebenzisa izixhumo zemishini ezishiselwe ukusebenzisa amalunga emishini acijile, ahlinzeka ngochungechunge lwezinzuzo zobuchwepheshe, ezomnotho kanye nezingokoqobo. Lokhu kubandakanya ukusebenza okuthuthukisiwe; ukufakwa nokugcinwa okushesha futhi kulula, nokunciphisa isisindo somoya. Izinkinga zokusebenza Emajoyini amapayipi ane-flange, ama-flange amabili okukhwelana ahlanganiswe ndawonye futhi i-gasket iyacindezelwa ukuze yakhe uphawu. Njengoba amabhawodi namantongomane elunga le-flange amunca futhi anxephezele amandla esistimu, ngokuhamba kwesikhathi, ngenxa yokuguquguquka kwengcindezi, ukucindezela kokusebenza kwesistimu, ukudlidliza, nokwanda nokufinyela okushisayo, amabhawodi namantongomane kungase kunwebe futhi kulahlekelwe ukuqina kwawo kwasekuqaleni . Lapho la mabhawodi ephumula i-torque, i-gasket izolahlekelwa uphawu lwayo lokucindezela, okuzodala amazinga ahlukene okuvuza. Ngokuya ngendawo kanye nomsebenzi wesistimu yamapayipi, ukuvuza kungabangela izindleko eziphezulu kanye nezingozi, okuholela ekunakekeleni / ukulungisa isikhathi sokuphumula kanye nobungozi. Ngemuva kokukhipha okuhlangene, i-gasket izodinga ukushintshwa ngoba i-gasket izonamathela endaweni ye-flange isikhathi esithile. Lapho uqaqa ilunga, ama-gaskets adinga ukukhunyulwa ezindaweni ezimbili ze-flange, futhi lezi zindawo zidinga ukuhlanzwa ngaphambi kokufaka ama-gaskets, okwandisa isikhathi sokulungisa. Ngenxa yamandla omshudo kanye nokwandiswa nokufinyela kwesistimu, i-flange gasket izophinde ikhiqize ukucindezelwa "i-deformation" ngokuhamba kwesikhathi, okungenye imbangela yokuvuza. Idizayini yejoyinti lepayipi lemishini eligobile inqoba lezi zinkinga zokusebenza. Okokuqala, kwakhiwa i-groove ekupheleni kwepayipi, futhi uxhumano lwepayipi lulungiswa ngokuxhumanisa okuhlanganisa i-elastomer gasket elastic, ephendula ukucindezela. Izindlu zokuhlanganisa zizungeza ngokuphelele i-gasket, iqinisa uphawu futhi ilungise endaweni, ngoba ukuhlanganisa kuhlanganisa futhi kwakha ukuhlangana okuthembekile emgodini wepayipi. Ubuchwepheshe bakamuva bokuxhumana buvumela amapayipi afinyelela kuma-intshi angu-24 (600 mm) ububanzi ukuze ahlanganiswe ngokugcwele ngamantongomane namabhawodi amabili ukuze avikele amalunga azibambayo. Ngenxa yobudlelwano bokuklama phakathi kweshubhu, i-gasket, nezindlu, ilunga lomshini lidala uphawu oluphindwe kathathu, oluthuthukiswayo lapho uhlelo lucindezelwa. I-Rigid and Flexible Couplings Amapayipi emishini ahlanganisiwe atholakala ngamafomu aqinile futhi avumelana nezimo, kokubili agunyazwe umphakathi wokuhlukanisa, futhi angasetshenziswa esikhundleni sendlela yokushisela/i-flange kumasistimu angu-30, kodwa kufanele ahambisane nezindinganiso zokufaka ngakunye. esungulwe yinhlangano yezitifiketi. Ama-couplings aqinile asetshenziswa, isibonelo, eduze kwezindawo ezifana nama-manifolds nama-valve, futhi kulula ukufinyeleleka nokushintsha esikhundleni sama-flange. Ngokwemvelo yokwakheka kwayo, ukuhlangana okuqinile nakho kuhlinzeka ngokuqina kwe-axial ne-radial okuqhathaniswa nama-flange noma amalunga ashiselwe. Ukuhlanganisa okuvumelana nezimo kunezinzuzo ezinhlelweni zokusebenza. Ngaphezu kokunyakaza kwamapayipi ngenxa yokwanda okushisayo noma ukudlidliza, ukunyakaza okuhlobene phakathi kwepayipi nesakhiwo esisekelayo nakho kulindeleke. Ukunwetshwa nokufinyela kubeka ingcindezi kuma-flange namapayipi, okungalimaza i-gasket ngokuhamba kwesikhathi. Uma lokhu kwenzeka, amalunga asengozini yokuvuza. I-coupling eguquguqukayo ene-grooved ingakwazi ukuthwala ukususwa kwepayipi ngendlela yokunyakaza kwe-axial noma ukuchezuka kwe-angular. Ngakho-ke, alungele ukufaka amapayipi amade, ikakhulukazi phakathi kwamabhulokhi amakhulu lapho umkhathi wolwandle ungabangela ukuba ama-flange axege ngokuhamba kwesikhathi, okuholela ekuvuzeni kanye nengozi yokuhlukana kwamapayipi. Ama-coupling aqinile kanye nama-flexible couplings nawo anenzuzo yokunciphisa umsindo nokudlidliza, ngaleyo ndlela aqede isidingo sezingxenye ezikhethekile zokunciphisa umsindo nezinsimbi zenjoloba ezibolayo noma izinto ezifanayo. Ukusetshenziswa kwemishini yamapayipi afakwe amapayipi kungasheshisa futhi kwenze kube lula ukufakwa nokunakekelwa, futhi kwandise ukusebenza kahle kwesistimu yamapayipi ebhodini. 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. Endabeni yesinye sezikhundla eziningi ezimisiwe ezinqunywa kuphela ngenani lezimbobo ku-flange, i-fitting kuphela noma i-valve ingashintshwa ukuze ifane nezimbobo zebhawudo. 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 ingafakwa kalula, futhi ipayipi nezingxenye zokukhwelana zingajikeleziswa ngokugcwele ngamadigri angu-360. Asikho isidingo sokuhlela iphethini yembobo ye-bolt, futhi ukuhlanganisa kungaqondiswa kunoma iyiphi indawo ezungeze ukujoyina. I-coupling ingazungeza ipayipi ukuze ifinyelele kalula amabhawodi futhi kube lula ukufinyelela ezisetshenziswayo. Ngokungeziwe ekususeni ukungaboni ngaso linye phakathi nenqubo yokufaka, umsebenzi wokuma kwe-360-degree wokuhlanganisa kanye nephrofayela encane uma kuqhathaniswa ne-flange yenza ukufakwa kwesistimu ye-groove kube ukukhetha okuhle kwezikhala eziwumngcingo. Ngaphezu kwalokho, isifaki singakwazi ukuqondisa wonke amabhawodi omhlangano endaweni eyodwa endaweni efanayo ukuze kube lula ukuhlolwa nokugcinwa kwesistimu. I-flange cishe iphindwe kabili ububanzi bangaphandle bepayipi lapho ixhunywe khona. Ngokwesilinganiso, ama-couplings ane-grooved ayingxenye kuphela yalo sayizi. Inzuzo yesayizi yomklamo omncane ikwenza kube ukukhetha okuhle kwezinhlelo ze-trough, ezifanele umsebenzi onesikhala esilinganiselwe, njengokungena kwamadekhi nezindonga. Leli qiniso lingalandelelwa emuva kuma-1930s, lapho ukuhlangana kwe-Victaulic kwaqala ukusetshenziswa ezindaweni zemikhumbi zaseBrithani. Isivinini somhlangano Ngenxa yokuthi ukuhlanganisa kunamabholithi ambalwa futhi imfuneko ye-torque ayidluli ama-intshi angu-12 (300 mm), ukufakwa kwamapayipi ane-grooved kushesha kakhulu kunokufakwa kwe-flange. Ngokungafani nama-flange okumelwe ashiselwe emaphethelweni epayipi, izingxenye ze-valve eyi-grooved azidingi ukushisela, okunciphisa isikhathi sokufaka, kuqede umonakalo ongase ube khona oshisayo ku-valve, futhi kunciphise izingozi zokuphepha ngokuqeda ukusebenza okuphezulu kokushisa. Ukuqhathaniswa kwemigqa ye-DIN 150 ye-ballast efakwe kusetshenziswa imikhiqizo ye-Victaulic grooved enezindlela zokuxhuma zendabuko kubonisa ukuthi isikhathi esiphelele sokufakwa esidingekayo sehliswe ngo-66% (amahora angu-150.47 namahora omuntu angu-443.16). Uma kuqhathaniswa nokufakwa kwama-couplings aqinile angu-60, isikhathi esidingekayo ukuze ufake ama-slide-in flange angu-52, izindololwane zokushisela nama-tee sinomehluko omkhulu kakhulu. Ukuhlanganisa kudinga amabhawodi amabili kuphela ukufinyelela usayizi wamapayipi angama-intshi angu-24 (600 mm). Ukuze uqhathanise, kububanzi obukhulu besayizi, i-flange idinga okungenani amasethi angu-20 amantongomane nama-bolts. Ngaphezu kwalokho, i-flange idinga ukusetshenziswa kwe-wrench yenkanyezi echitha isikhathi ukuze iqiniswe nge-wrench ekhethekile yokulinganisa nokuqinisekisa ukuthi ukucaciswa kwe-torque okulungile kufinyelelwa. Ubuchwepheshe beshubhu eligobile buvumela ukusetshenziswa kwamathuluzi ezandla ajwayelekile ukuze kuhlanganiswe ukuhlanganisa, futhi uma iphedi yokukhwelana yendlu yokuhlanganisa ithinta insimbi ibe yinsimbi, ilunga lingafakwa kahle. Ukuhlola okubonakalayo okulula kungaqinisekisa ukuhlangana okulungile. Ngakolunye uhlangothi, ama-flange awanikezi isiqinisekiso esibonakalayo: indlela kuphela yokuqinisekisa ukuhlangana okufanele ukugcwalisa nokucindezela uhlelo, hlola ukuvuza futhi uqinise kabusha amalunga njengoba kudingeka. Ukugcineka Isistimu yamapayipi ayizinsika inezici ezifanayo zokusheshisa ukufakwa-amabhawodi ambalwa futhi azikho izidingo zetorque-futhi yenza ukugcinwa kwesistimu noma iguqule umsebenzi osheshayo nolula. Ukuze ufinyelele ipompo noma i-valve, isibonelo, khulula amabhawodi amabili okuhlanganisa bese ususa indlu kanye ne-gasket ekuhlanganyeleni. Kuhlelo lwe-flange, amabhawodi amaningi adinga ukususwa. Lapho ufaka kabusha i-flange, inqubo efanayo yokuqinisa ibhawudi edla isikhathi kufanele yenziwe ngesikhathi sokufakwa kokuqala. Ngenxa yokuthi asikho isidingo sokuphinda kuqiniswe, ukuhlanganisa kusindisa umsebenzi omningi wokulungisa ojwayelekile ohlobene nama-flange. Ngokungafani nama-flanges lapho ukucindezeleka okuguquguqukayo kusetshenziswa kuma-washers, amantongomane nama-bolts, ama-couplings abamba ama-washers avela ngaphandle kwejoyinti yepayipi ngamandla okucindezela aqondile. Ngaphezu kwalokho, njengoba i-gasket yokuhlanganisa ayithwali ingcindezi ephezulu, akudingekile ukuyishintsha ngokuvumelana nesimiso esivamile sokugcinwa, futhi i-gasket ye-flange idinga ukushintshwa lapho uhlelo luhlakazwa ukuze lugcinwe. Ukuze kuncishiswe umsindo nokudlidliza kwesistimu, isistimu ye-flange idinga ukusebenzisa imibhobho yerabha noma amapayipi aluka. Lezi zinto zingase zehluleke ngenxa yokunwetshwa ngokweqile, futhi ngaphansi kokuguga nokuklebhuka okuvamile, zidinga ukushintshwa ngokwesilinganiso njalo ngemva kweminyaka eyi-10, okungaholela ezindlekweni nasekuphelelweni kwesistimu. Kodwa-ke, amalunga amapayipi anemifantu esebenza ngomshini angandisa impilo yesistimu. Banekhono lokuzivumelanisa nokudlidliza kwesistimu futhi banciphise ingozi yokuhluleka okuhlangene ngaphandle kwesidingo semikhiqizo ekhethekile edinga ukugcinwa okuvamile noma ukushintshwa. Amawasha asentwasahlobo anwebekayo aqukethwe kuma-couplings aguquguqukayo futhi aqinile ahlala isikhathi eside futhi angakwazi ukumelana nezingcindezi ezinkulu zokusebenza kanye nemithwalo yezikhathi ezithile. Uhlelo lungacindezelwa futhi lucindezelwe ngokuphindaphindiwe ngaphandle kokukhathala kwe-elastomer gasket. Izingxenye ze-valve ezingasindi zivame ukwakhiwa yizingxenye ze-flange. Nokho, le ndlela yokuxhuma ingeza isisindo esingadingekile ohlelweni lwamapayipi. Ivalvu ye-flange engu-6 intshi (150 mm) iqukethe i-lug butterfly valve. I-valve uvemvane ixhunywe ku-flange yentamo eshiselwe, futhi amabhawodi ayisishiyagalombili namantongomane axhunywe ohlangothini ngalunye lwevalvu, enesisindo esingamakhilogremu angu-85. Ukuhlanganiswa kwama-valve angama-intshi angu-6 (150 mm) kusebenzisa i-valve uvemvane ene-grooved end, ipayipi eline-grooved end, nama-coupling amabili aqinile ukuze kuxhunywe lezi zingxenye. Isisindo singamakhilogremu angu-35, okungama-58% alula kunomhlangano we-flanged. . Ngakho-ke, umhlangano we-valve oyi-grooved uyisinqumo esihle embonini yokwakha umkhumbi. Uma usebenzisa imikhiqizo ye-Victaulic grooved esikhundleni sendlela yokuxhumana evamile, ukuqhathanisa okungenhla komugqa we-ballast we-DIN 150 ofakiwe kukhombisa ukuncipha kwesisindo ngo-30% (2,164 pounds vs. 3,115 pounds). Ama-sliding flange angu-52, amasethi ebhawodi namawasha, kuyilapho ama-couplings aqinile angama-60 enza isisindo esiningi ohlelweni lokushisela/i-flange. Emapayipini anobukhulu obuhlukahlukene, isisindo singancishiswa ngokusebenzisa amapayipi ahlanganisiwe esikhundleni sama-flange. Ubukhulu bokunciphisa buxhomeke kububanzi bepayipi kanye nohlobo lwamalungu asetshenzisiwe. Esivivinyweni kusetshenziswa i-Victaulic Style 77 coupling (ukuhlanganisa okunzima kakhulu ebangeni) ukuze kuxhunywe ipayipi, ukufakwa okuphelele komhlangano ogobile uma kuqhathaniswa nama-flange amabili ama-slide-in alula we-PN10 Isisindo siphansi kakhulu. Ukulahlekelwa kwesisindo kubhalwe kanje: 4 amayintshi (100 mm) -67%; amayintshi angu-12 (300 mm)-54%; 20 amayintshi (500 mm)-60.5%. Ukusetshenziswa kohlobo olulula oluguquguqukayo lwe-75 noma uhlobo oluqinile lwe-07 ama-couplings kanye/noma ama-flange asindayo angakwazi ukuzuza kalula ukuncipha kwesisindo esingu-70%. Isibonelo, ikhithi ye-flange engu-24-intshi (600 mm) esetshenziswa kusistimu ye-TG2 inesisindo esingamaphawundi angu-507, kuyilapho izingxenye ezifanayo ezisebenzisa izixhumi ze-Victaulic zinesisindo esingamaphawundi angu-88 kuphela. Ohlelweni olukhethiwe, indawo yemikhumbi, esebenzisa ukuxhuma okunemigodi ngaphezu kwamaflange, yehlisa isisindo semikhumbi esekela ngasogwini ngamathani angu-12 kanti emikhunjini yokuhamba ngomkhumbi ngamathani angu-44. Izinzuzo ezingokomnotho zobuchwepheshe bokusebenzisa imikhumbi kubanikazi bemikhumbi zisobala: ukunciphisa isisindo kusho ukwandisa inani lempahla noma abagibeli nokunciphisa ukusetshenziswa kukaphethiloli. Lokhu futhi kwenza ukuphatha uhlelo lwamapayipi omkhumbi kube lula. Indlela ethuthukayo Amasistimu amapayipi ase-grooved anezinzuzo ezinkulu ngaphezu kwamasistimu amapayipi ane-flanged ngenxa yesivinini sawo sokuwafaka, ukugcinwa kwawo kanye nesisindo esincishisiwe. Lezi zici, ezihambisana nezinye izinzuzo ezinjengokwethembeka, ukuqondanisa kalula kanye nezingozi eziphansi zokuphepha, kwenze abanikazi bemikhumbi, onjiniyela kanye nezindawo zemikhumbi ukuba bakhethe amasistimu emishini acijile esikhundleni sama-flange. Umkhuba okhulayo ekusetshenzisweni kobuchwepheshe be-groove usekelwa abahlinzeki bemishini (njengama-heaters, ama-box cooler nama-coolers) kanye nabakhiqizi be-valve kanye ne-compressor, abaningi babo manje abahlinzeka ngemikhiqizo yabo Nikeza ukuxhumana kokuphela kwe-grooved. Ububanzi bezinsizakalo ezingasebenzisa izihlanganisi zamapayipi ane-grooved bukhula kancane kancane. Ngokusebenza kwayo ngempumelelo ezinhlelweni zamanzi, i-Victaulic izoqhubeka nomlando wayo omude wokuqamba izinto ezintsha ukuze kuthuthukiswe ama-gasket angashi futhi ithole isitifiketi sohlobo lokuwasebenzisa ezinsizeni zikaphethiloli zasolwandle.
