Kev Txij Nkawm Ntawm Cov Tswj Valve

Kev tswj lub valve muaj cov yam ntxwv ntawm cov qauv yooj yim thiab txhim kho kom ntseeg tau, tab sis vim tias nws ncaj qha rau txheej txheem nruab nrab, nws qhov kev ua tau ncaj qha cuam tshuam rau qhov zoo ntawm lub system thiab ib puag ncig muaj kuab paug, yog li cov tswj valve yuav tsum tswj thiab tsis tu ncua, tshwj xeeb tshaj yog rau qhov hnyav thiab cov haujlwm tseem ceeb Hauv qee lub sijhawm, ntau tus yuav tsum tau them rau kev saib xyuas ua haujlwm. Qhov tseem ceeb soj ntsuam:

1. Sab hauv ntawm phab ntsa ntawm lub ntsuas dej

Rau kev tswj cov hlua siv nyob rau hauv qhov siab siab txawv thiab qhov teeb meem hauv nruab nrab, sab hauv phab ntsa ntawm lub cev lub cev thiab roj teeb ntawm lub diaphragm valve feem ntau cuam tshuam thiab corroded los ntawm nruab nrab. Lub siab tiv thaiv thiab tiv thaiv corrosion yuav tsum kuaj xyuas.

2. Lub rooj zaum kos

Thaum cov tswj valve ua haujlwm, vim qhov infiltration ntawm qhov nruab nrab, qhov xov nyob sab hauv rau qhov kho qhov chaw ntawm lub rooj zaum yog qhov cuam tshuam rau kev xeb thiab lub rooj zaum ua xoob. Ua tib zoo saib xyuas nws thaum tshuaj xyuas. Rau cov li qub uas ua haujlwm nyob rau hauv qhov siab siab qhov sib txawv, xyuas seb qhov chaw sib khi ntawm lub rooj zaum puas ntsoog.

3. Nplaj

Lub lig xov yog qhov txav tau thaum lub sijhawm ua haujlwm hloov kho. Nws feem ntau tau yaig thiab corroded los ntawm nruab nrab. Nws yog ib qho tsim nyog yuav tsum tau ua tib zoo kuaj seb txhua ntu ntawm tus spool puas xeb thiab hnav thaum lub sij hawm tu, tshwj xeeb tshaj yog nyob rau hauv qhov xwm txheej ntawm qhov siab txawv qhov txawv. (Vim yog cavitation), yuav tsum tau them nyiaj. Lub tub ntxhais valve yuav tsum tau hloov thaum nws muaj teeb meem loj. Ntxiv rau, kev saib xyuas yuav tsum tau them rau seb lub pob valve muaj qhov tshwm sim zoo sib xws, los yog qhov sib txuas nrog lub ntsej muag valve yog qhov xoob xoob.

4. Cov ntawv cog lus Diaphragm

GG quot; O" ntiv nplhaib thiab lwm daim gaskets. Lub diaphragm thiab" O" -shaped gasket nyob hauv tus tswj valve yuav tsum raug kuaj xyuas kev laus thiab kab nrib pleb.

5. Sealing packing

Kev saib xyuas yuav tsum tau them rau seb lub PTFE ntim thiab sealing lubricating roj yog cov laus, thiab seb cov mating saum npoo puas, thiab yuav tsum tau hloov thaum tsim nyog.

Kev tswj valve, tseem hu ua kev tswj lub siab, yog lub ntsiab yam ntawm kev ua yeeb yam. Los ntawm txais cov tswj cov teeb liab tawm los ntawm lub ntsuas hluav taws xob tswj tau tswj, nws siv lub zog ua haujlwm hloov pauv cov dej ntws. Lub regulating valve feem ntau yog tsim ntawm cov actuator thiab lub pob valve. Raws li lub zog siv los ntawm cov actuator, kev tswj qhov hluav taws xob tuaj yeem muab faib ua peb hom: pneumatic, hluav taws xob thiab hydraulic, hu ua pneumatic tswj lub qhov hluav taws xob nrog cua compressed ua cov khoom siv hluav taws xob, hluav taws xob tswj valve nrog hluav taws xob ua qhov hluav taws xob, thiab cov kua nruab nrab (Xws raws li cov roj, thiab lwm yam.) Raug tsav-electro-hydraulic tswj li qub. Tsis tas li ntawd, raws li lawv lub luag haujlwm thiab cov yam ntxwv, muaj cov solenoid li qub, hluav taws xob, ntse, thiab fieldbus tswj li qub.
