Ib tug trunnion pob valveyog ib hom valve uas siv lub pob rotating raws li nws cov core control element. Kev khiav tawm ntawm kev tshaj tawm yog tswj los ntawm kev sib cuag lossis sib cais ntawm lub pob thiab lub rooj zaum valve. Lub "trunnion" nyob rau hauv nws lub npe yog hais txog kev txhawb nqa ncej nyob rau ntawm ob sab ntawm lub pob. Qhov kev tsim no muab nws qhov tshwj xeeb zoo nyob rau hauv siab - siab, loj - txoj kab uas hla, thiab kev ua haujlwm nyuaj, ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv hauv kev lag luam tswj cov kua dej.
A trunnion pob valveFeem ntau muaj lub cev lub cev, lub hau npog, lub pob valve, lub rooj zaum ntawm lub rooj, lub tog raj kheej, thiab cov khoom siv ua haujlwm.
Lub valve lub cev yog lub ntsiab tivthaiv, feem ntau yog ua los ntawm cov hlau cam khwb cia lossis stainless hlau, muab kev tiv thaiv corrosion zoo. Lub valve npog txuas mus rau lub valve lub cev thiab ruaj ntseg lub pob valve thiab lub rooj zaum. Lub pob valve yog qhov tseem ceeb ntawm lub pob trunnion pob valve, feem ntau yog ua los ntawm stainless hlau, muab kev sib khi zoo heev.
Lub rooj zaum lub rooj zaum nrog lub pob valve, feem ntau yog ua los ntawm cov khoom siv elastic, ua kom lub valve sealing kev ua tau zoo. Lub valve qia txuas lub valve npog thiab lub pob valve, xa cov kev khiav hauj lwm quab yuam. Cov cuab yeej ua haujlwm tuaj yeem yog phau ntawv lossis tsis siv neeg, siv los tswj qhov qhib thiab kaw ntawm lub valve.
