Ivalvu yeplagi eLubricated yoMzi-mveliso ePhakamileyo yoMgangatho oPhezulu weGesi yendalo Umthengisi wefektri waseTshayina Umvelisi
Yintoni ivalvu yeplagi egcotyiweyo igesi yendalo?
Ivalvu yeplagi egcotyiweyo Iqulathe umngxuma ophakathi kweplagi ecaleni kwe-axis yayo. Lo mngxuma uvaliwe ezantsi kwaye ufakwe i-sealant-injection fitting phezulu. I-sealant ifakwa kwi-cavity, kwaye i-check valve engaphantsi kwe-injection fitting ithintela i-sealant ukuba ingahambi ngendlela echaseneyo.
Ukuze kuncitshiswe i-torque ye-valve ze-plug ezityibiliziweyo zesihlalo sesinyithi,Ivalvu yeplagi egcotyiweyoziqanjwe kwaye zisetyenziswa kakhulu. Ukongeza kwiimpawu zeevalvu zeplagi ezixutywe ngeoyile eqhelekileyo, iivalvu zeplagi ezixineneyo zoxinzelelo nazo zineempawu ezilandelayo:
- 1. Ikhowuni yeplagi yevalvu yeplagi elungelelanisiweyo yoxinzelelo ifakelwe kwindawo eguqulweyo. Kukho ivalvu yokujonga kwinxalenye ephezulu yekhowuni yeplagi. Xa ivalvu ivaliwe, ngenxa yomahluko kwindawo esezantsi nephezulu yekhowuni yeplagi, ioyile yokutywina enoxinzelelo oluphezulu efakweyo ibangela ukuba umzimba weplagi uphakanyiswe phezulu, ukuze umzimba weplagi kunye nomphezulu wokutywina wevalvu zitywinwe ngcono.
- 2. Xa ivalvu ivuliwe, uxinzelelo kwigumbi elisezantsi lomzimba wevalvu lulinganiswa noxinzelelo oluphakathi kumbhobho. Ioyile yokutywina enoxinzelelo oluphezulu kwigumbi eliphezulu ibangela ukuba umzimba weplagi utyhalelwe ezantsi, kwaye kuvela umsantsa omncinci phakathi kwekhowuni yeplagi kunye nomphezulu wokutywina womzimba wevalvu, i-torque yomzimba weplagi ejikelezayo iyancipha ngempumelelo.
Iimpawu eziphambili zevalvu yeplagi egcotyiweyo
Iimpawu kunye neenzuzo zeIvalvu yeplagi egcotyiweyo
- 1. Le mveliso inesakhiwo esifanelekileyo, uphawu oluthembekileyo, ukusebenza kakuhle kunye nenkangeleko entle.
- 2.Inesakhiwo soxinzelelo olulinganiselayo oluguquguqukayo kunye nokusebenza kokukhanya nokuvula.
- 3. Kubekwa umngxuma weoyile phakathi komzimba wevalvu nomphezulu wesitywino, onokufaka igrisi yesitywino ukwandisa amandla esitywino.
