Lubricated plug valve imakhala ndi kabowo pakati pa pulagi m'mbali mwake.Bowoli limatsekedwa pansi ndipo limayikidwa ndi jekeseni wa sealant pamwamba.Chosindikiziracho chimalowetsedwa mumtsempha, ndipo valavu yoyang'ana pansi pa jekeseniyo imalepheretsa chosindikizira kuti chisamayende mozungulira.Chosindikiziracho chimatuluka kuchokera pakatikati kudzera m'mabowo ozungulira kulowa m'malo opaka mafuta omwe amatalikirana ndi utali wa pulagiyo.

Pofuna kuchepetsa makokedwe a ochiritsira zitsulo mpando mafuta mavavu pulagi,zotsekemera zotsekemeraamapangidwa ndipo amagwiritsidwa ntchito kwambiri.Kuphatikiza pa mawonekedwe a mavavu a pulagi wamba omwe ali ndi mafuta, mavuvu olimba a pulagi alinso ndi izi:

• 1.The pulagi koni ya kuthamanga moyenera lubricated pulagi valavu wokwera mu inverted malo.Pali valavu yoyang'ana pamwamba pa pulagi cone.Pamene valavu yatsekedwa, chifukwa cha kusiyana kwa malo odulidwa apamwamba ndi otsika a plug cone, jekeseni wotsekemera wotsekemera mafuta amachititsa kuti thupi la pulagi likwezedwe mmwamba, kotero kuti thupi la pulagi ndi malo osindikizira a valve akhoza kukhala. osindikizidwa bwino.
• 2. Vavu ikatsegulidwa, kupanikizika m'chipinda chapansi cha thupi la valve kumakhala koyenera ndi kuthamanga kwapakati mu payipi.Mafuta osindikizira othamanga kwambiri m'chipinda cham'mwamba amachititsa kuti thupi la pulagi likankhidwe pansi, ndipo kusiyana pang'ono kumawoneka pakati pa pulagi koni ndi kusindikiza pamwamba pa thupi la valve, torque ya plug yozungulira thupi imachepetsedwa bwino.
