Tsis tas li ntawd, cov khoom siv sealing yuav tsum muaj qhov kub thiab txias tsis kam tiv thaiv kev foob tsis ua haujlwm. (3) Kev hnav khaub ncaws: Rau qhov hnyav hnyav, lub pob li qub uas muaj cov ntaub ntawv hnav-resistant xws li cemented carbide thiab ceramics tuaj yeem xaiv. Nyob rau tib lub sijhawm, xaiv cov khoom sib khi nrog kev hnav zoo, xws li polytetrafluoroethylene, graphite thiab lwm yam. Peb, kev siv lub pob valve thiab cov lus qhia txog kev saib xyuas 1. Kev tshuaj xyuas ua ntej siv: Ua ntej siv lub pob valve, xyuas qhov tseeb ntawm lub pob valve kom paub meej tias lub pob, lub cev valve, foob thiab lwm yam tsis muaj kev puas tsuaj thiab tsis zoo. Nyob rau tib lub sijhawm, xyuas seb cov kav dej txuas txuas puas huv si kom tsis txhob muaj impurities cuam tshuam rau kev ua haujlwm ntawm lub pob valve. 2. Kev ua haujlwm raug: Thaum ua haujlwm ntawm lub pob valve, nws yuav tsum tau ua raws li cov txheej txheem kev ua haujlwm tau teev tseg kom tsis txhob muaj kev quab yuam ntau dhau lossis ua haujlwm tsis zoo uas ua rau muaj kev puas tsuaj rau lub pob valve. Nyob rau hauv lub xeev kaw, lub siab yuav tsum tau zam rau lub sij hawm ntev, thiaj li tsis ua rau lub foob puas. 3. Kev saib xyuas tsis tu ncua: Ua kom lub pob valve tsis tu ncua, xyuas qhov kev sib khi ua haujlwm, kev ua haujlwm yooj yim, thiab lwm yam, kom ntseeg tau tias lub pob valve yeej ib txwm ua haujlwm zoo. Rau qhov hnav, qhov chaw puas, yuav tsum tau kho lossis hloov lub sijhawm. Iv. Xaus Pob li qub tau siv dav hauv kev lag luam, thiab kev xaiv thiab siv cov txheej txheem yuav tsum tau ua tiav raws li cov kev ua haujlwm tshwj xeeb thiab cov yam ntxwv ntawm kev tshaj tawm. Kuv vam tias cov lus qhia kev tshaj lij uas muab los ntawm cov kws tshaj lij hauv kev siv pob valve hauv Suav teb tuaj yeem muab cov lus qhia siv tau rau koj thaum xaiv pob valve.
