Farqiga u dhexeeya shaabadda jilicsan iyo shaabadda adag ee waalka
2022-08-17
Farqiga u dhexeeya shaabadda jilicsan iyo shaabadda adag ee waalka Marka lagu daro waalka dahaarka u adkaysta daxalka, valve shaabad guud ee jilicsan ayaa loola jeedaa kabka ama kursiga mid ka mid ah labada qalab ee aan biraha ahayn (badanaa PTFE, caag, iwm.) foomka la xidhay. ee waalka. Saamaynta shaabadeynta ee shaabadda jilicsan ayaa ka fiican, laakiin rakibidda dhuumaha, nadiifinta nidaamka ayaa laga yaabaa inay ka tagto qashinka aan nadiif ahayn ama ka yar (sida alxanka alxanka, fiilooyinka birta, iwm.), waxay ku qulqulayaan valve nidaaminta, si sahlan loo xoqo jilicsanaanta. kursiga daboolka ama spool, si ay qadarka dheecaanku u korodho, kalsoonida shaabadu waa liidataa. Sidaa darteed, doorashada qaab dhismeedka shaabadda jilicsan waa in ay tixgeliyaan nadiifinta dhexdhexaadka ah iyo dhuumaha qulqulaya adag ka hor inta aan la hawlgelin. Shaabada jilicsan ee Valve iyo farqiga shaabadda adag: (1) Shaabada jilicsan Marka lagu daro waalka dahaarka u adkeysanaya daxalka, shaabadda guud ee jilicsan waxaa loola jeedaa kaboolka ama kursiga mid ka mid ah labada qalab ee aan biraha ahayn (badanaa PTFE, caag, iwm. ) qaabka shaabadeysan ee waalka. Saamaynta shaabadeynta shaabadda jilicsan ayaa ka fiican, laakiin rakibidda dhuumaha, nadiifinta nidaamka ayaa laga yaabaa inay ka tagto qashinka aan nadiif ahayn ama ka yar (sida alxanka alxanka, fiilooyinka birta, iwm.), waxay ku qulqulayaan valve nidaaminta, si sahlan loo xoqo jilicsanaanta. kursiga daboolka ama spool, si ay qadarka dheecaanku u korodho, kalsoonida shaabadu waa liidataa. Sidaa darteed, doorashada qaab dhismeedka shaabadda jilicsan waa in ay tixgeliyaan nadiifinta dhexdhexaadka ah iyo dhuumaha qulqulaya adag ka hor inta aan la hawlgelin. (2) Shaabad adag Shaabad adag iyo dusha sare ee daawaha u adkeysanaya xirashada ayaa ka fiican in la gooyo valves-yada. Habkan iyadoo la tixgelinayo shaabadeynta iyo sidoo kale tixgelin nolosha adeegga iyo isku halaynta, inkastoo index warshadda ay tahay 10-6 ~ 10-8 oo keliya, ma gaari karto saameynta jilicsanaanta eber ee jilicsan, laakiin ku filan si ay u buuxiso shuruudaha jarista dhagan. waana mid waara, marka laga eego dhinaca dhaqaalaha waa mid aad u kharash badan.
