Kev ua haujlwm ntawm qhov ntse valve hluav taws xob actuator yuav cuam tshuam ncaj qha rau kev ua haujlwm zoo ntawm tag nrho cov kev tswj hwm. Vim tias qhov ntse valve hluav taws xob actuator yog nyob rau hauv kev sib cuag ncaj qha nrog kev tswj nruab nrab ntawm qhov chaw, qhov chaw ua haujlwm hnyav heev, yog li nws yooj yim los tsim ntau yam tsis ua haujlwm. Hauv cov txheej txheem tsim khoom, ntxiv rau kev tshem tawm cov kev ua txhaum no txhua lub sijhawm, kev saib xyuas tsis tu ncua thiab kev tshuaj xyuas yuav tsum tau ua. Tshwj xeeb tshaj yog rau cov tswj valve nrog tshwj xeeb kev ua haujlwm tsis zoo ib puag ncig, yuav tsum tau them nyiaj ntau rau kev saib xyuas thiab tu tsis tu ncua.
Kev saib xyuas txhua hnub ntawm pneumatic tswj valve:
Thaum lub valve tswj siv graphite-asbestos li muab tub lim, lubricating roj yuav tsum tau muab ntxiv rau lub muab tub lim ib zaug txhua peb lub hlis los xyuas kom meej tias cov tswj valve yog hloov tau thiab yooj yim rau siv. Yog hais tias lub packing siab cap pom tias tsawg heev, cov packing yuav tsum tau supplemented. Yog tias PTFE ntim tau pom tias yuav tsum tau ua kom tawv, nws yuav tsum tau hloov lub sijhawm; Kev khiav hauj lwm ntawm lub regulating valve yuav tsum tau them sai sai rau thaum lub sij hawm ncig xyuas, thiab lub valve txoj hauj lwm qhia thiab regulator tso zis yuav tsum tau xyuas. Nws puas haum.
