Okwesibili, ukuhlolwa kokubukeka I-valve kufanele ihlolwe ngokubonakalayo ngaphambi kokufakwa 1. Indawo yokuvula nokuvala yevalvu ngesikhathi sokuthutha kufanele ihlangabezane nalezi zidingo ezilandelayo · Amavalvu, ama-globe valves, ama-throttle valves, ama-valve okulawula, ama-butterfly valves, ama-valve aphansi kanye namanye ama-valve kufanele. ibe sendaweni evaleke ngokugcwele I-valve yokuxhuma, izingxenye zokuvala i-valve yebhola kufanele zibe sesimweni esivulekile esigcwele · I-valve ye-diaphragm kufanele ibe sendaweni evaliwe futhi ingavaleki ngokuqinile ukuze kuvinjwe umonakalo ku-diaphragm · I-disc ye-valve yokuhlola izoba ivalwe futhi iqiniswe 2, ivalvu ngeke yonakale, izingxenye ezingekho, ukugqwala, i-nameplate off kanye nezinye izenzakalo, futhi umzimba wevalvu akufanele ungcolile 3. Zombili iziphetho zevalvu kufanele zivikelwe. Isibambo noma ukusebenza kwesondo lesandla kufanele kube okuguquguqukayo futhi kube lula, kungabi yinto ebambekayo 4. Uma umzimba we-valve uphonsa, indawo yawo kufanele ibe bushelelezi futhi ibushelelezi, ngaphandle kokuqhekeka, izimbobo zokhiye, ama-tracholes, ama-pores, ama-burrs nokunye ukukhubazeka; Lapho ubumba ngaphandle komzimba we-valve, indawo engaphezulu kufanele ingabi nemifantu, ama-interlayers, isikhumba esinzima, amabala nokunye ukukhubazeka. I-5, i-valve yokuhlola i-disc noma isenzo se-spool iyaguquguquka futhi inembile, akukho okucacile, ukufuduka noma i-skew phenomenon 6, i-valve yokuphepha yohlobo lwe-spring kufanele ibe nophawu lokuhola, i-valve yokuphepha yohlobo lwe-lever kufanele ibe nedivayisi yokubeka isando esindayo 7. Indawo engaphakathi ye-valve umzimba ohlanganiswe nenjoloba, i-koqweqwe lwawo kanye nepulasitiki kufanele ibe bushelelezi futhi ibushelelezi, isendlalelo se-lining sihlanganiswe ngokuqinile ne-matrix, futhi akukho ukuqhuma, i-bubble nezinye iziphambeko. Ingaphezulu lesendlalelo se-lining kufanele lihlolwe yi-high-frequency generator spark electric generator, futhi akukho ukuwohloka kongqimba lwe-lining (isenzakalo esikhanyayo esimhlophe) esifanelekayo 8, indawo yokuvalwa kwe-valve flange kufanele ihlangabezane nezidingo, futhi kungabikho imihuzuko ye-radial Kubalulekile ukugcina. lawa maphuzu engqondweni mayelana nokufakwa kwe-valve! (a) isiqondiso sokufakwa kwe-valve kanye nokuma kwama-valve amaningi anokuqondisa, njenge-globe valve, i-throttle valve, i-valve yokunciphisa ingcindezi, i-valve yokuhlola, njll., uma ifakwe ngokuhlehlayo, izophazamisa ukusetshenziswa komphumela kanye nempilo (njenge i-throttle valve), noma ivele ingasebenzi (njenge-valve yokunciphisa ingcindezi), futhi ibangele ingozi (njenge-valve yokuhlola). I-valve evamile, kunophawu lokuqondisa emzimbeni we-valve; Uma kungenjalo, kufanele ikhonjwe ngendlela efanele ngokuvumelana nesimiso sokusebenza kwe-valve. Igumbi le-valve elizungeze i-valve yembulunga alilingani, liwuketshezi lokulivumela lisuka phansi liye phezulu ngembobo ye-valve, ngakho ukumelana noketshezi kuncane (kunqunywa ukuma), ukonga umsebenzi ovulekile (ngenxa yokucindezela okuphakathi phezulu) , ivaliwe ngemva kokupakishwa kwengcindezi ephakathi, kulula ukuyilungisa, yingakho i-valve yomhlaba ingakwazi ukufaka iqiniso. Amanye ama-valve anezici zawo siqu. Ngenisa kanye nekhaya sicela uchofoze indawo yokufaka i-valve, kufanele kube lula ukusebenza: ngisho noma ukufakwa kunzima okwesikhashana, kodwa futhi nomsebenzi wesikhathi eside womqhubi. Isondo lesandla se-valve nokuqondisa kwesifuba (ngokuvamile amamitha angu-1.2 ukusuka endaweni yokusebenza), ukuze ukuvulwa nokuvala kwe-valve kube umzamo omncane. Isondo lesandla sevalvu yaphansi kufanele libheke phezulu futhi lingatsheki ukuze kugwenywe ukusebenza kabi. I-valve yomshini wodonga incike emishinini, futhi opharetha kufanele ashiywe endaweni emile. Ukuze ugweme ukusebenza kwesibhakabhaka, ikakhulukazi i-asidi ne-alkali, imidiya enobuthi, ngaphandle kwalokho ayiphephile. Isango akufanele liguqulwe (okungukuthi, isondo lesandla liphansi), ngaphandle kwalokho okuphakathi kuzogcinwa esikhaleni sekhava isikhathi eside, kulula ukugqwala isiqu, futhi kwezinye izidingo zenqubo taboo. Kunzima kakhulu ukufaka esikhundleni sokupakisha ngesikhathi esifanayo. Vula AMAVAVAVA WE-STEM GATE, UNGAFAKI ngaphansi komhlaba, ngaphandle kwalokho ngenxa yokugqwala okumanzi kwesiqu esivelile. Phakamisa i-valve yokuhlola, ukufakwa ukuze uqinisekise ukuthi i-valve disc ime mpo, ukuze i-lift iguquguquke. Swayipha i-valve yokuhlola, lapho ifakiwe ukuze kuqinisekiswe ukuthi izinga lephinikhodi, ukuze linyakaze liguquguquke. I-valve yokunciphisa umfutho izofakwa iqonde epayipini elivundlile, futhi akufanele itshekele kunoma iyiphi indlela. (2) Umsebenzi wokwakha ukufakwa kwe-valve ukwakhiwa kokufakwa kokufakwa kufanele kuqaphele, ungashayi izinto eziphukayo ezenziwe nge-valve. Ngaphambi KOKUFAKA, IVAVU KUFANELE IYAHLOLWA UKUZE kubhekwe imininingwane KANYE namamodeli ukuze kubonakale noma yimuphi umonakalo, ikakhulukazi wesiqu. Futhi zungeza izikhathi ezimbalwa ukuze ubone ukuthi ihlanekezelwe yini, ngoba ngesikhathi sokuthutha, isiqu se-valve kulula ukusishaya sigwegwile. Futhi *** udoti ku-valve. UMA UPHAKAMISA IVAVAVU, INTAMBO AKUMELE IBOSHWE ESANDWENI NOMA ISIQINISEKISO UKUZE UGWEME UKULIMALA KWALEZI ZINgxenyana. KUFANELE KUBOSHWE EMHLABENI. Umugqa lapho i-valve ixhunywe khona kufanele ihlanzwe. Umoya ocindezelwe ungasetshenziselwa ukushaya amafayili e-iron oxide, isihlabathi, i-welding slag nezinye izinhlobo. Lezi mfucumfucu, akulula nje ukunwaya indawo yokuvala ye-valve, izinhlayiya ezinkulu zemfucumfucu (njenge-welding slag), kodwa futhi zingavimba i-valve encane, ukuze ukwehluleka kwayo. Lapho UFAKA I-VALVE YESIKREWU, UKUPHAKISWA KOKUVALWA (INTAMBO KAmafutha e-aluminium NOMA Ibhande lezinto ezibonakalayo le-PTFE RAW) kufanele liboshwe kuntambo yepayipi, ungangeni ku-valve, ukuze ugweme ivolumu yememori ye-valve, ithinte ukugeleza okuphakathi. Lapho ufaka ama-valve e-flange, qaphela ukuqinisa ama-bolts ngokulinganayo nangokulinganayo. I-valve flange kanye ne-pipe flange kufanele ihambisane, imvume inengqondo, funa i-valve ikhiqize ukucindezela okukhulu, ngisho nokuqhekeka. Ngezinto eziqinile futhi hhayi amandla aphezulu we-valve, ukunakwa okukhethekile kufanele kukhokhwe. I-valve ezoshiselwa ngepayipi kufanele ifakwe endaweni eshiselwe kuqala, khona-ke ingxenye evaliwe izovulwa ngokugcwele, bese i-welded ifile. (3) Izinyathelo zokuvikela amavalvu amanye amavalvu kumele abe nesivikelo sangaphandle, okuwukugcina ukushisa nokugcina amakhaza. I-insulation layer kwesinye isikhathi ixutshwa nemigqa yesitimu esishisayo. Hlobo luni lwe-valve okufanele lube ukushisa noma ukubanda, ngokuya ngezidingo zokukhiqiza. Empeleni, lapho medium valve ukunciphisa izinga lokushisa kakhulu, kuzothinta ukusebenza kahle ukukhiqizwa noma valve eqandisiwe, udinga ukufudumala, ngisho mix ukushisa; Lapho i-valve ingenalutho, ingalungile ekukhiqizeni noma ibangele isithwathwa nezinye izinto ezimbi, udinga ukubanda. Izinto zokufakelwa i-asbestos, uboya be-slag, uboya bengilazi, i-perlite, i-diatomite, i-vermiculite, njll; Izinto zokupholisa zingukhokho, i-perlite, igwebu, ipulasitiki nokunye. (4) I-bypass kanye nensimbi amanye ama-valve, ngaphezu kwezindawo zokuvikela ezidingekayo, kodwa futhi ane-bypass kanye nensimbi. I-bypass ifakiwe. Kulula ukulungisa isicupho. Amanye ama-valve, nawo afakwe i-bypass. Ukufakwa kwe-bypass kuncike esimweni se-valve, ukubaluleka, kanye nezidingo zokukhiqiza. (ezinhlanu) ukupakisha ukufaka esikhundleni sevalvu yesitoko, okunye ukupakisha akubanga kuhle, kanti okunye akuhambisani nokusetshenziswa kwe-medium, edinga ukuvala indawo yokupakisha. I-Valve factory ayikwazi ukucabangela ukusetshenziswa kwezinkulungwane zezinhlobo ezahlukene zemidiya, ibhokisi lokupakisha lihlala ligcwele impande evamile, kodwa lapho lisetshenziswa, kufanele livumele ukupakisha phakathi ukuze livumelane. Uma ushintsha ukupakisha, cindezela uzungeleze ngomjikelezo. Umthungo ngamunye wendandatho ukuya kuma-degree angama-45 kufanelekile, indandatho futhi ikhale ivuleke ngama-degree angama-180. Ukuphakama kokupakisha kufanele kucabangele i-leeway ukuze indlala iqhubeke nokucindezela, futhi manje kuyadingeka ukuvumela ingxenye engezansi ye-gland icindezele ikamelo lokupakisha ekujuleni okufanele, okungase kube ngu-10-20% wokujula okuphelele igumbi lokupakisha. Kuma-valve afunayo, i-engeli ehlangene ingama-degree angama-30. Umthungo ophakathi kwendandatho nendandatho inyakaza ngamadigri ayi-120. Ngaphezu kokupakisha, kodwa futhi ngokusho kwesimo esithile, ukusetshenziswa kwe-rubber O-ring (irabha yemvelo imelana no-60 degrees Celsius i-alkali ebuthakathaka, i-butadiene injoloba imelana no-80 degrees Celsius ikristalu kawoyela, i-Fluorine iraba imelana nezinhlobonhlobo zokubola. imidiya engaphansi kuka-150 degrees Celsius) indandatho emithathu eyisitaki ye-polytetrafluoron (imelana nemidiya egqwalayo eqinile engaphansi kuka-200 degrees Celsius) indandatho yesitsha senayiloni (imelana no-120 degrees Celsius ammonia, alkali) nokunye ukugcwaliswa okwenza. Ungqimba lwetheyiphu ye-TEflon eluhlaza lungathuthukisa umphumela wokuvala futhi lunciphise ukugqwala kwe-electrochemical kwesiqu se-valve. Lapho ucindezela isithokelo, vula isiqu ngesikhathi esifanayo ukugcina nxazonke ngokulinganayo, futhi uvimbele ukufa kakhulu, qinisa indlala ukuphoqa ngokulinganayo, awukwazi ukutsheka.
