Umgangatho oPhakamileyo woShishino oluthungelweyo lweglowubhu yeglowubhu Umniki-mveliso waseTshayina woMzimveliso
Yintoni ivalve yeglowubhu enemisonto?
Ivalve yeglowubhu enemisontoluyilo olukhethekileyo lweevalvu zeglowubhu ezinobungakanani obuncinci.
Njengevalve yeglowubhu, inazo zonke iimpawu zevalve yeglowubhu, ivuleke ngokukhawuleza kwaye ivale.
iivalvu.njengesiqhelo, iindawo zokuvula nezokuvala zisango, ezikwimilo ye-wedge, yiyo loo nto zithiywe njengevalve yesango eliwuweji.icala lentshukumo yesango lithe gqolo kwicala lolwelo.Ivalve yesango lewedge inokuvulwa ngokupheleleyo kwaye ivalwe ngokupheleleyo kwaye ayinakuhlengahlengiswa kwaye icinezelwe.Ivalve yesango yenzelwe ukusetyenziswa nokuba ivuleke ngokupheleleyo okanye ivalwe ngokupheleleyo.
kodwa iIvalve yeglowubhu enemisontoineempawu zayo.yenziwe ngentsimbi yekhabhoni eyenziwe ngentsimbi, insimbi engenasici, intsimbi yealloy, enomzimba obambeneyo, ifanelekele uxinzelelo oluphezulu lwe-fluid.ibhonethi inokubotshwa, idityaniswe kwaye ivalwe ngoxinzelelo, ngokweemeko zokusebenza.
Iimpawu eziphambili zevalve yeglowubhu ene Threaded
Iimpawu eziphambili ze-API602ivalve yeglowubhu yentsimbi eyenziweyo
- I-1) Ukunyuka kwesiqu kunye ne-acme echanekileyo kabini intambo yokusebenza ngokukhawuleza.
- 2)Umzimba ukuya kwijoyinti yebhonethi eyilelwe ukufaka umthwalo ofanayo kwigasket ukuqinisekisa ukuvuza kwetywina.
- I-5) I-Backseat eyenzelwe ukukhulula uxinzelelo lwangasemva kwi-stem packing xa uhleli ngokupheleleyo.Ukutshintsha ukupakishwa kwe-stem phantsi koxinzelelo akukhuthazwa.
- I-6) Ukupakishwa kwe-Stem yenzelwe ulawulo oluphezulu lokuvuza okuphumayo kwi-atmoshphere.Izinga lokuvuza elisezantsi kakhulu liqinisekiswa kukugqiba kakuhle kwindawo yokutywinwa kwesikhondo, ukucocwa okucuthiweyo kwediametrical kunye nolawulo lokuthi tye kwesiqu.
