Yuav tswj li cas tswj li qub

Lub valve tswj muaj cov yam ntxwv ntawm cov qauv yooj yim thiab txhim khu kev qha, tab sis vim hais tias nws yog ncaj qha nyob rau hauv kev sib cuag nrog cov txheej txheem nruab nrab, nws cov kev ua tau ncaj qha cuam tshuam rau qhov zoo ntawm lub system thiab ib puag ncig muaj kuab paug, yog li ntawd lub valve tswj yuav tsum tsis tu ncua tswj thiab overhauled, tshwj xeeb tshaj yog nyob rau hauv lub system. rau qhov hnyav thiab tseem ceeb. Qee zaum, yuav tsum tau saib xyuas ntau dua rau kev ua haujlwm tu. Cov cheeb tsam tseem ceeb los xyuas:
1. Sab hauv ntawm lub valve
Rau kev tswj valve siv nyob rau hauv kev sib txawv siab thiab corrosive xov xwm, lub puab phab ntsa ntawm lub valve thiab lub diaphragm ntawm lub diaphragm valve feem ntau cuam tshuam thiab corroded los ntawm nruab nrab, yog li ntawd lub siab tsis kam thiab corrosion kuj yuav tsum tau soj ntsuam.
2. Valve rooj
Thaum cov tswj valve ua haujlwm, vim yog qhov infiltration ntawm nruab nrab, sab hauv ntawm cov xov siv los kho lub rooj zaum valve yog yooj yim corroded thiab lub rooj zaum valve yog xoob, yog li yuav tsum tau them nyiaj rau nws thaum lub sij hawm soj ntsuam. Rau cov li qub ua haujlwm nyob rau hauv siab sib txawv, xyuas seb lub sealing nto ntawm lub rooj zaum valve puas puas.
3. Spool
Lub spool yog ib qho txav tau thaum lub sijhawm ua haujlwm hloov kho, thiab nws yog qhov hnyav tshaj plaws eroded thiab corroded los ntawm nruab nrab. Thaum lub sij hawm txij nkawm, nws yuav tsum tau ua tib zoo xyuas seb qhov chaw ntawm lub spool puas yog corroded thiab hnav, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm high pressure sib txawv. Kev hnav ntawm spool yog qhov hnyav dua. (Vim qhov tshwm sim cavitation), yuav tsum tau them nyiaj mloog. Thaum lub valve tseem raug puas tsuaj loj, nws yuav tsum tau hloov. Tsis tas li ntawd, kev saib xyuas yuav tsum tau them rau seb lub qia valve puas muaj qhov tshwm sim zoo sib xws, lossis kev sib txuas nrog lub valve tseem yog xoob.
4. Diaphragm
"O" rings thiab lwm cov ntsaws ruaj ruaj. Xyuas seb lub diaphragm thiab "O"-shaped gasket nyob rau hauv lub valve tswj yog laus los yog tawg.
5. Ntim ntim
Ua tib zoo saib seb lub PTFE ntim thiab sealing roj puas yog kev laus, thiab seb qhov mating nto puas, thiab lawv yuav tsum tau hloov thaum tsim nyog.
Lub regulating valve, tseem hu ua tus tswj valve, yog hom tseem ceeb ntawm actuator. Los ntawm kev tau txais cov teeb liab tswj cov zis los ntawm lub regulating control unit, cov kua dej yog hloov los ntawm lub hwj chim ua hauj lwm. Regulating li qub feem ntau muaj cov actuator thiab lub valve. Raws li lub zog siv los ntawm nws qhov sib txuam actuator, lub regulating valve yuav muab faib ua peb hom: pneumatic, hluav taws xob thiab hydraulic, uas yog, pneumatic regulating valve nrog compressed cua raws li lub hwj chim qhov chaw, hluav taws xob regulating valve nrog hluav taws xob raws li lub hwj chim. qhov chaw, thiab cov kua nruab nrab. (xws li roj, thiab lwm yam.) Siab-powered electro-hydraulic tswj li qub. Tsis tas li ntawd, raws li lawv cov dej num thiab cov yam ntxwv, muaj cov solenoid li qub, hluav taws xob, kev txawj ntse, thiab cov tsheb npav-hom tswj li qub.
