Ibhalansi yoxinzelelo oluguqulweyo itshisiwe ivalvu yeplagi
Yintoni i-Inverted pressure balance lubricated plug valve?
Ivalvu yeplagi egcotyiweyo Iqulathe umngxuma ophakathi kweplagi ecaleni kwe-axis yayo. Le mngxuma ivaliwe ezantsi kwaye ifakwe 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. I-sealant iphuma kwi-cavity esembindini ngemingxunya ye-radial iye kwi-lubricant grooves edlula kubude bomphezulu wesihlalo seplagi.
Ukuze kuncitshiswe i-torque ye-valve ze-plug ezityibiliziweyo zesihlalo sesinyithi,ibhalansi yoxinzelelo oluguqulweyo iivalvu zeplagi ezithanjiswe nge-lubricantziqanjwe 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.
- 3. 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 etywiniweyo ikhethelwe iimeko zokusebenza zokwenyani.
