Threaded nto siv los ruaj ntseg tswj li qub yog raug rau corrosion

Thaum lub sij hawm ua hauj lwm ntawm lub rooj zaum tswj valve, vim yog infiltration ntawm nruab nrab, lub puab nto ntawm cov xov siv los kho lub rooj zaum valve yog yooj yim corroded thiab lub rooj zaum valve yog loosened. Ua tib zoo saib thaum kuaj xyuas. Rau li qub ua haujlwm nyob rau hauv siab sib txawv, nws tseem yuav tsum tau xyuas seb lub sealing nto ntawm lub rooj zaum valve puas puas.

Lub valve tseem ceeb thiab lub valve tseem ceeb yog cov khoom txav tau thaum lub sijhawm ua haujlwm txias. Lawv hnyav eroded thiab corroded los ntawm nruab nrab. Thaum lub sij hawm txij nkawm, nws yuav tsum tau ua tib zoo xyuas seb qhov sib txawv ntawm cov tub ntxhais valve puas yog corroded thiab hnav, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej ntawm kev kub siab sib txawv. Rau qhov hnyav (vim cavitation), yuav tsum tau saib xyuas. Yog tias lub valve tseem raug puas tsuaj loj, nws yuav tsum tau hloov. Tsis tas li ntawd, koj yuav tsum tau them sai sai rau seb lub qia valve kuj muaj qhov tshwm sim zoo sib xws, lossis kev sib txuas nrog lub valve tseem yog xoob.

Diaphragm "O" rings thiab lwm yam gaskets. Lub diaphragm thiab "O"-puab gasket nyob rau hauv lub regulating valve yuav tsum tau soj ntsuam rau kev laus thiab tawg. Lub sealing packing yuav tsum tau them sai sai rau seb lub ntim polytetrafluoroethylene thiab lub sealing lubricating roj puas yog kev laus, thiab seb qhov kev koom tes nto puas, thiab yuav tsum tau hloov thaum tsim nyog.
