Ivalvu yeplagi eLubricated yoMzi-mveliso ePhakamileyo yoMgangatho oPhezulu Umthengisi wefektri waseTshayina Umvelisi
Yintoni ivalvu yeplagi egcotyiweyo yeNatural Gas?
Ivalvu yeplagi egcotyiweyo Igesi yendalo 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 egcotyiweyo Igesi yendaloziqanjwe 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. Kwiimeko zobushushu obuphezulu, ukwanda kobushushu kweplagi kunokufunxwa kukunyuka nokuwa kwayo. Ivalvu yeplagi ethanjiswe ngeoyile, nangona ukusetyenziswa kwe-oyile ethanjiswe ngeoyile kunokunciphisa ngokufanelekileyo i-torque yokuvula nokuvala, kodwa kunokubangela ungcoliseko lwe-medium. Ke ngoko, i-oyile ethanjiswe ngeoyile ikhethelwe iimeko zokusebenza zokwenyani.
Iimpawu eziphambili zevalvu yeplagi egcotyiweyo yendalo
Iimpawu kunye neenzuzo zeIvalvu yeplagi egcotyiweyo Igesi yendalo
- 1.Inesakhiwo soxinzelelo olulinganiselayo oluguquguqukayo kunye nokusebenza kokukhanya nokuvula.
- 2. Kubekwa umngxuma weoyile phakathi komzimba wevalvu nomphezulu wesitywino, onokufaka igrisi yesitywino ukwandisa amandla esitywino.
- 3. Izinto ezisetyenziswa kwiindawo kunye nobukhulu beeflanges zinokucwangciswa ngokufanelekileyo ngokwemeko yokusebenza yokwenyani yeemfuno zabathengi, ukuze kuhlangatyezwane neemfuno ezahlukeneyo zobunjineli.
