I-EPDM Rubber Coated Wedge Rising Stem Resilient Seat Gate Valve yoMvelisi waseTshayina
Yintoni ivalvu yesango leRubber wedge?
Njengeevalvu zesango le-wedge eziqhelekileyo, iindawo zokuvula nezokuvala zevalvu yesango le-Rubber wedge ziyisango, ezikwimo ye-wedge, yiyo loo nto zibizwa ngokuba yivalvu yesango le-wedge. Ivalvu yesango le-wedge inokuvulwa ngokupheleleyo kwaye ivalwe ngokupheleleyo kwaye ayinakulungiswa kwaye iqhotyiswe. Ivalvu yesango yenzelwe ukusetyenziswa nokuba ivuliwe ngokupheleleyo okanye ivalwe ngokupheleleyo, kuba ngenxa yesimo see-obturators zayo ezinemo ye-wedge, ukuba ibisebenza ivuliwe kancinci, bekuya kubakho ukulahleka okukhulu koxinzelelo kwaye umphezulu wokutywina uya konakaliswa xa kuchaphazeleka lulwelo.Uphawu oluphambili lwevalvu yesango le-DIN-EN kukuba umphezulu wayo wokutywina phakathi "kwesango" kunye nesihlalo sayo uthe tyaba, nto leyo ebangela ukulahleka koxinzelelo oluncinci kakhulu.
Iimpawu eziphambili zevalvu yesango leRubber wedge
Uphawu oluPhambili
- Iiflanges: EN1092-1, PN10-16-25-40-63-100, okanye ezinye iiflanges zobukhulu obuceliweyo
- I-wedge ye-CF8M ene-Stellite eqinileyo nayo iyafumaneka xa uyicela.
- Ukumelana nokuhamba kwamanzi okuncinci kunye nokulahlekelwa koxinzelelo, ngenxa yendlela yokuhamba ethe tye kunye ne-wedge evulekileyo ngokupheleleyo.
- Imo yayo incinci, isakhiwo sayo silula, yenza kube lula ukwenziwa nokugcinwa kwayo, kunye noluhlu olubanzi lwezicelo.
- Kudala ukuvala kunye nokuhamba kancinci kwe-wedge, akukho nto inokwenzeka ngesando samanzi kwiivalvu zesango le-wedge.
