Ukuthi ukukhethwa kwendlela yokuxhumanisa phakathi kwevalvu yebhabhathane kanye nepayipi noma imishini kulungile noma cha kuzothinta ngqo amathuba okusebenza, ukuconsa, ukuconsa kanye nokuvuza kwevalvu yepayipi. Izindlela ezivamile zokuxhumanisa ivalvu zifaka: uxhumano lwe-flange, uxhumano lwe-wafer, uxhumano lokushisela izinqe, uxhumano olunemicu, uxhumano lwe-ferrule, uxhumano lwe-clamp, uxhumano oluzivala kanye nezinye izinhlobo zokuxhumanisa.
A. Ukuxhumeka kwe-Flange
Ukuxhumeka kwe-Flange kuyintoivalvu yebhabhathane elijiyilengama-flange kuzo zombili izinhlangothi zomzimba we-valve, ahambisana nama-flanges epayipini, futhi afakwa epayipini ngokubopha ama-flanges. Ukuxhumeka kwe-Flange kuyindlela yokuxhuma esetshenziswa kakhulu kuma-valve. Ama-Flange ahlukaniswe ngobuso obuyi-convex (RF), ubuso obuyisicaba (FF), ubuso obuyi-convex kanye nobuso obuyi-concave (MF), njll.
B. Ukuxhumeka kwe-Wafer
Ivalvu ifakiwe phakathi kwama-flange amabili, kanye nomzimba wevalvu we-ivalvu yebhabhathane eliyi-waferngokuvamile inembobo yokubeka ukuze kube lula ukufakwa nokubeka.
C. Ukuxhumeka kwe-Solder
(1) Ukuxhumeka kokushisela izinqe: Zombili iziphetho zomzimba wevalvu zicutshungulwa zibe imigoqo yokushisela izinqe ngokwezidingo zokushisela izinqe, ezihambisana nemigoqo yokushisela yephayiphi, futhi ziqiniswa ephayiphini ngokushisela.
(2) Ukuxhumeka kokushisela isokhethi: Zombili iziphetho zomzimba wevalvu zicutshungulwa ngokwezidingo zokushisela isokhethi, futhi zixhunywe nepayipi ngokushisela isokhethi.
D. Uxhumano olunezintambo
Ukuxhumeka okunezintambo kuyindlela elula yokuxhuma futhi kuvame ukusetshenziselwa ama-valve amancane. Umzimba we-valve ucutshungulwa ngokwezinga ngalinye lentambo, futhi kunezinhlobo ezimbili zentambo yangaphakathi nentambo yangaphandle. Ihambisana nentambo epayipini. Kunezinhlobo ezimbili zokuxhumeka okunezintambo:
(1) Ukuvala okuqondile: Imicu yangaphakathi neyangaphandle idlala indima yokuvala ngqo. Ukuze kuqinisekiswe ukuthi ukuxhumana akuvuzi, kuvame ukugcwaliswa ngowoyela we-lead, i-thread hemp kanye ne-PTFE raw material tape; phakathi kwayo kusetshenziswa kakhulu i-PTFE raw material tape; le nto inokumelana okuhle nokugqwala kanye nomphumela omuhle kakhulu wokuvala. Kulula ukuyisebenzisa nokuyigcina. Uma uyihlukanisa, ingasuswa ngokuphelele ngoba iyifilimu enganamatheli, engcono kakhulu kunamafutha we-lead kanye ne-thread hemp.
(2) Ukuvala ngokungaqondile: amandla okuqinisa intambo adluliselwa ku-gasket phakathi kwalezi zindiza ezimbili, ukuze i-gasket idlale indima yokuvala.
Uxhumano lwe-E. ferrule
Ukuxhumeka kwe-ferrule kuthuthukiswe ezweni lakithi eminyakeni yamuva nje. Umgomo wayo wokuxhuma nokuvala ukuthi uma inathi iqinisiwe, i-ferrule icindezelwa, ukuze unqenqema lwe-ferrule lulume odongeni lwangaphandle lwepayipi, futhi ubuso bekhoni yangaphandle ye-ferrule buxhunywe esihlanganyelweni ngaphansi kwengcindezi. Ingaphakathi lomzimba lisondelene kakhulu nobuso obunciphile, ngakho-ke ukuvuza kungavinjelwa ngokuthembekile. Njenge-valve yezinsimbi. Izinzuzo zalolu hlobo lokuxhuma yilezi:
(1) Usayizi omncane, isisindo esincane, isakhiwo esilula, ukuqaqwa nokuhlanganiswa okulula;
(2) Amandla okuxhuma aqinile, ububanzi bokusetshenziswa, ukumelana nokucindezela okuphezulu (1000 kg/cm2), izinga lokushisa eliphezulu (650 ° C) kanye nokushaqeka nokudlidliza;
(3) Izinto ezahlukahlukene zingakhethwa, ezifanele ukulwa nokugqwala;
(4) Izidingo zokunemba komshini aziphezulu;
(5) Ilungele ukufakwa ezindaweni eziphakeme.
Njengamanje, ifomu lokuxhuma i-ferrule selisetshenziswe kweminye imikhiqizo yamavalvu amancane ezweni lakithi.
F. Uxhumano olunemiphetho
Lena indlela yokuxhuma okusheshayo, idinga amabhawodi amabili kuphela, futhiivalvu yebhabhathane elisekugcineni elinomgogodlakufanelekile ekucindezelweni okuphansiamavalvu ebhabhathaneezivame ukuhlakazwa, njengezivalo zangasese.
G. Ukuxhumana okuziqinisayo kwangaphakathi
Zonke izinhlobo zokuxhuma ezingenhla zisebenzisa amandla angaphandle ukuze zinciphise ingcindezi ye-medium ukuze kufezwe ukuvala. Okulandelayo kuchaza ifomu lokuxhuma eliziqinisayo kusetshenziswa ingcindezi ephakathi.
Indandatho yayo yokuvala ifakwa kwikhoni yangaphakathi futhi yakha i-engeli ethile lapho uhlangothi lubheke khona. Ingcindezi ye-medium idluliselwa kwikhoni yangaphakathi bese iya kwindandatho yokuvala. Ebusweni bekhoni ye-engeli ethile, kukhiqizwa amandla amabili ezingxenye, elilodwa eline-. Umugqa ophakathi womzimba we-valve uhambisana nengaphandle, kanti elinye licindezelwa odongeni lwangaphakathi lomzimba we-valve. Amandla okugcina amandla okuziqinisa. Uma ingcindezi ephakathi inkulu, kulapho amandla okuziqinisa aphezulu. Ngakho-ke, leli fomu lokuxhuma lifanelekela ama-valve okucindezela okuphezulu.
Uma kuqhathaniswa nokuxhumeka kwe-flange, konga izinto eziningi kanye namandla abasebenzi, kodwa futhi kudinga ukulayisha kusengaphambili okuthile, ukuze kusetshenziswe ngokuthembekile lapho ingcindezi evalvini ingekho phezulu. Amavalvu enziwe kusetshenziswa isimiso sokuziqinisa ngokuvamile amavalvu anomfutho ophezulu.
Kunezinhlobo eziningi zokuxhuma ama-valve, isibonelo, amanye ama-valve amancane angadingi ukususwa ahlanganiswa ngamapayipi; amanye ama-valve angewona awensimbi axhunywe ngama-socket njalo njalo. Abasebenzisi bama-valve kufanele baphathwe ngokwesimo esithile.
Qaphela:
(1) Zonke izindlela zokuxhuma kumele zibhekisele ezindinganisweni ezifanele futhi zicacise amazinga okuvimbela ukufakwa kwevalvu ekhethiwe.
(2) Ngokuvamile, ipayipi elikhulu kanye nevalvu kuxhunywe ngeflange, kanti ipayipi elincane kanye nevalvu kuxhunywe ngentambo.
Isikhathi sokuthunyelwe: Juni-18-2022
