Umgangatho oPhezulu wevalve yeglowubhu yeShishini yoxinzelelo oluphezulu umthengisi wemveliso waseTshayina uMvelisi
Yintoni ivalve yeglowubhu yoxinzelelo oluphezulu?
API602ivalve yeglowubhu yoxinzelelo oluphezululuyilo 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 njengevalufa yesango elisikere.Ivalve yesango le wedge inokuvulwa ngokupheleleyo kwaye ivalwe ngokupheleleyo kwaye ayinakulungelelaniswa kwaye icinezelwe.Ivalve yesango yenzelwe ukuba isetyenziswe okanye ivuleke ngokupheleleyo okanye ivalwe ngokupheleleyo, kuba ngenxa yokumila kwe-obturators yayo enemilo ye-wedge. , ukuba ibisebenza ivulekile ngokuyinxenye, bekuya kubakho ilahleko enkulu yoxinzelelo kwaye umphezulu wokutywina uya konakaliswa phantsi kwempembelelo yolwelo.
Iimpawu eziphambili zevalve yeglowubhu yoxinzelelo oluphezulu ?
Iimpawu eziphambili ze-API602ivalve yeglowubhu yoxinzelelo oluphezulu
- 1) Ukunyuka kwesiqu ngokuchaneka kwe-acme intambo ephindwe kabini ukuze usebenze 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 eliphantsi kakhulu liqinisekiswa kukugqiba kakuhle kwindawo yokutywinwa kwesikhondo, ukucocwa okucuthiweyo kwediametrical kunye nolawulo lokuthi tye kwesiqu.
- 7)Bellows seal iyafumaneka ngesicelo
