Umgangatho ophezulu woShishino we-intshi ye-intshi engama-48 yevalvu yesango umthengisi wemveliso waseTshayina uMenzi
Yintoni i-intshi ezingama-48 ivelufa yesango?
iAPI600 Iivalvu zesango elikhulu 48 intshi yesango,ukusebenza okufanayo kwe-prinpical kunye ne-machanism njengesiqhelo se-API600 yeevalvu zesango le-wedge.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.iyilwe kwaye yenziwe ngokomgangatho waseMelika i-API600, ASME B16.34, isiphelo esineflang ukuya ku-ASME B 16.5, kwaye yavavanywa ngokwe-API598, inomsebenzi othile kunye nothintelweyo ukukhulula okanye ukuvala ukuhamba kweentlobo ezahlukeneyo zolwelo kwimibhobho.
ngoko kukho iifektri ezingaphantsi kwe-10 ezinokwenzaAPI600 ubukhulu obukhulu iivalvu zesango 48 intshi yevalve yesangoUkuya kuthi ga kwi-intshi ezingama-72. Ukumela omnye wabenzi bevalvu abakhulu e-China, i-Nantong High kunye ne-middel pressure valve co, Ltd (TH), kwiivalvu zabo ezinkulu zesango, iivalvu zesango loxinzelelo oluphezulu.
Iimpawu eziphambili ze-48 intshi yevalve yesango
Iimpawu eziphambili
- 3)Universal trim:API trim 1(13Cr),trim 5(Stellite Gr.6 faced both wedge and seat) kunye netrim 8(Stellite Gr.6 faced on seat) ziyafumaneka.kunye namanye amanani etrim ngokuxhomekeke kwizixhobo zomzimba ezikhethiweyo .
- 4)iiFlanges:ASME B16.5 kunye ASME B16.47 for 28"-72"
- 5) Ukutywinwa kwe-Bi-directional
- 6) Ukuchasana nokuhamba okuncinci kunye nokulahleka koxinzelelo, ngenxa yendlela yokuhamba ngokuthe tye kunye ne-wedge epheleleyo evulekile.
- 7)Isihlalo sobuso be-Stellite Gr.6 i-alloy eqinile, iphantsi kwaye igqitywe kwisipili esigqityiweyo.,I-Stellite hardfaced CF8M wedge nayo iyafumaneka xa uyicela.
