Kaw-off valve: pab tau cov ntaub

Kaw-off valve yog ib raj dej valve caij siv nyob rau hauv tej yam. Nyob rau hauv xws li ib tug ntaus ntawv lub zog ntawm tus txhav tas neeg nyob rau hauv thaum uas tig mus axis ntawm lub ntsiab khiav ntawm cov kua hauv.

Kaw-off thiab regulating valve nrog ib tug hluav taws xob executing mechanism taw qhia kom paub mus hloov cov ua hauj lwm nruab nrab flow, uas tsiv los ntawm lub raj dej. Kaw-off valve tej zaum yuav tsim nyob rau ntawm bronze, hlau thiab hlau, nws yog siv los tswj cov kua los yog roj khiav los ntawm lub raj dej, raws li zoo raws li lub caij uas blocks lub txaus. Yog hais tias peb coj raws li ib lub hauv paus rau lub kev faib ntawm tus tsim nta ntawm lub ntaus ntawv, raws li tau zoo raws li nws cov hom phiaj, nws tseem yog lub kaw-off solenoid valve, uas enables cov kev tswj ntawm qhov chaw nyob rau hauv lub system ntawm ib tug deb, raws li zoo raws li flanged thiab grooved-hom qub.

Muaj ntau ntau ntau ntau yam ntawm no hom ntawm valve. Xaiv ntawm ib tug ib tug nyob ntawm cov yam ntxwv ntawm cov kev siv technology tshiab txheej txheem, raws li zoo raws li kev pab raws qib uas raug rau kev nyab xeeb shutoff valve. Ib qho tseem ceeb tshaj yog cov tshuab, qhov twg nws yog siv.

Li qub yog dav faib sufficiently kom muaj raws li cov kev ua ntawm li qub, uas tso cai rau muab kev zoo siab rau kev sib khi nyob rau hauv lub locking lub cev, nyob rau hauv tus qauv ntawm tus dais no yog heev yooj yim. Li qub siv rau gaseous thiab kua kawm muaj ib tug ntau ntawm cov ua hauj lwm cov khoom: siab thiab kub. Lawv feem ntau yog siv nyob rau hauv pipelines muaj ib tug me me txoj kab uas hla, txij li thaum nqi loj dua tau mus fim ib qhov teeb meem nyob rau hauv uas tshuam tsub kom tus quab yuam yuav tsum tau rau valve tswj, raws li zoo raws li tham kev tsim kho, los xyuas kom meej kom zoo zaum valve raug muab tso rau hauv lub eeb lub cev.

Kaw-off valve muaj ib tug xov tooj ntawm zoo:

- tau siv nyob rau hauv kub siab thiab kub, nqus, txhoj puab heev thiab corrosive npuas;

- yooj yim ntawm txij nkawm thiab kev siv technology tshiab kev pab ncaj qha mus rau hauv lub lag luam.

By tsim nta li qub zoo xws li qub, li cas los xij, ib tug yuav tsum muaj qhov sib txawv yog txoj kev yuav tawm mus rau lub shutter li qub muab cov kev pab:

- siab qhib lub shutter yuav tsum tau ib tug me me stroke, yog li tus luj ntawm lub ntaus ntawv thiab kuj muaj qhov siab qhov yog txaus me me;

- ceev ceev ntawm lub qhov rooj li qub muab ib tug yooj yim npaum li nyob rau hauv lub qub;

- cov lus qhib thiab kaw ntawm lub valve shutter yuav luag cais tsis sib haum xeeb foob, uas zoo heev thiaj li muaj qhov degree ntawm coj;

- raws li qhov cuab lub zog sib khi bellows yog tso cai rau siv.

Slam-kaw-off valve kuj muaj tej yam tsis zoo:

- siab txaus kuj, hais tias cov nqe vaj lug kub uas muaj ib tug txiav txim txoj kab uas hla thiab kev kub ceev zog puag ncig tsim teeb meem loj zog losses, ua rau cov kev xav tau los txhim kho lub thawj zaug system siab;

- txoj kab uas hla txwv cov uas duav txhua yam ntawm daim ntawv thov ntawm cov valve;

- nyob rau hauv feem ntau constructs tuag aav nyob qhov twg muaj ib tug cia hnab khib txhua yam impurities ntawm cov ua hauj lwm nruab nrab, uas zoo heev pab txoj kev corrosion nyob rau lub valve lub cev.

Nyob rau hauv txhua rooj plaub, qhov no zoo ntawm qhov cuab lub zog yog dav siv.
