Lub hom phiaj ntawm lub rooj vag valve yog dab tsi?

A rooj vag valve yog hom valve uas tswj cov dej ntws los ntawm kev qhib lossis kaw lub rooj vag hauv lub cev valve. Nws yog feem ntau siv rau hauv cov ntawv thov kev lag luam los tswj cov dej ntws, gases, thiab lwm yam kua hauv cov kav dej.

Nws yog tsim los qhib tag nrho lossis kaw tag nrho, tso cai rau kev tswj xyuas cov kua dej kom zoo thiab meej. Thaum qhib tag nrho, lub rooj vag hauv lub valve lub cev yog ua raws li cov kev taw qhia ntawm kev khiav, tsim ib txoj hauv kev ncaj rau cov kua dej kom dhau mus. Thaum kaw tag nrho, lub rooj vag yog perpendicular mus rau cov kev taw qhia ntawm ntws, zoo thaiv cov dej ntws.

1. Lub cev valve: Lub cev lub cev yog lub ntsiab ntawm lub rooj vag valve. Nws feem ntau yog ua los ntawm cam khwb cia hlau lossis hlau thiab muaj lub zog siab thiab corrosion kuj uas lwm cov ntaub ntawv tsis muaj.
2. Rooj vag: Lub rooj vag yog qhov tseem ceeb ntawm lub rooj vag valve. Nws yog nyob rau hauv lub valve lub cev thiab feem ntau yog ua los ntawm stainless hlau los yog cam khwb cia hlau. Lub luag haujlwm ntawm lub rooj vag yog los tswj cov dej ntws thiab paub qhov qhib thiab kaw los ntawm kev tswj xyuas phau ntawv lossis hluav taws xob.
3. Gasket: Muaj ob hom gaskets nyob rau hauv lub qhov rooj li qub, uas yog mos gaskets thiab hlau gaskets. Lawv txhua tus tsim nyog rau qhov chaw ua haujlwm sib txawv thiab cov kev xav tau siab.
4. Kev khiav hauj lwm mechanism: Kev khiav hauj lwm mechanism ntawm lub rooj vag valve tuaj yeem yog phau ntawv lossis hluav taws xob. Lub lifting mechanism los yog iav mechanism feem ntau yog siv los tswj qhov qhib thiab kaw ntawm lub qhov rooj.
5. Inlet thiab qhov hluav taws xob flanges: Lub inlet thiab qhov hluav taws xob flanges ntawm lub rooj vag li qub feem ntau yog siv cov txheej txheem flange kev sib txuas, uas pab txhawb kev txhim kho thiab kho.
6. Cov khoom siv txhawb zog: Cov khoom siv txhawb zog yog cov khoom tseem ceeb los tiv thaiv cov rooj vag li qub los ntawm kev tawg vim muaj kev kub ntxhov ntau dhau nyob rau hauv high-pressure los yog high-flow. Lawv tuaj yeem ua rau hauv daim ntawv ntawm cov nplhaib txhawb nqa, cov hlua khi, thiab cov phaj txhawb nqa.

Lub rooj vag valve cov ntaub ntawv muaj xws li: stainless hlau, forged steel, cam khwb cia hlau, cam khwb cia hlau, tooj liab (tseem muab faib ua bronze, tooj dag), thiab lwm yam.

Cov khoom ntawm stainless hlau rooj vag valve yog muab faib ua 304 stainless hlau rooj vag valve, 316 stainless hlau rooj vag valve, thiab lwm yam Forged steel rooj vag valve: Forged steel rooj vag valve yog tsim rau me me-inch pipelines nrog Class 150 ~ 2500 thiab ua hauj lwm kub ntawm { {5}} ~ 425 degree (carbon steel) lossis -29 ~ 500 degree (stainless hlau). Nws yog siv los txiav tawm lossis txuas qhov nruab nrab hauv cov kav dej. Cam khwb cia steel rooj vag valve: Tag nrho cov rooj vag li qub ua los ntawm cov ntaub ntawv hlau hlau thiab nrum rau hauv cov khoom ua ke hu ua cam khwb cia steel rooj vag li qub. Cam khwb cia hlau rooj vag valve: Cam khwb cia hlau rooj vag valve yog muab faib ua grey cam khwb cia hlau rooj vag valve thiab ductile hlau rooj vag valve, uas feem ntau yog siv nyob rau hauv cov kav dej.

Lub rooj vag valve yog cov khoom siv tswj dej ntau siv dav hauv kev txuag dej, kev tsim kho, metallurgy, roj av, tshuaj lom neeg kev lag luam thiab lwm yam kev lag luam. Nws txoj haujlwm yog los tswj cov dej ntws hauv cov kav dej los ntawm kev qhib thiab kaw ntawm lub valve, yog li ua tiav lub hom phiaj ntawm kev tswj cov dej ntws, txiav tawm cov kua dej thiab ua kom muaj kev nyab xeeb ntawm cov kav dej.

Ua ntej tshaj plaws, qhov tseem ceeb tshaj plaws ntawm lub rooj vag valve yog tswj kev ntws. Los ntawm kev kho qhov qhib thiab kaw qib ntawm lub valve, tus nqi ntws ntawm cov kua hauv cov kav dej tuaj yeem raug txwv kom ua tau raws li qhov xav tau ntawm cov txheej txheem tsim khoom lossis siv. Piv txwv li, hauv cov dej hauv nroog, cov dej ntws ntws thiab cov dej ntws hauv qab yog sib koom ua ke los ntawm kev kho qhov qhib thiab kaw ntawm lub qhov rooj kom ntseeg tau cov dej ruaj khov thiab cov dej txaus txaus.

Qhov thib ob, lub rooj vag li qub tuaj yeem siv los txiav tawm thiab txiav cov kua dej. Thaum lub raj xa dej yuav tsum tau nres cov dej ntws mus ib ntus, lossis thaum muaj xwm txheej loj tshwm sim thiab cov kua yuav tsum tau kaw sai, lub qhov rooj li qub yog cov khoom siv tseem ceeb. Piv txwv li, nyob rau hauv high-pressure pipelines nyob rau hauv lub petrochemical kev lag luam, thaum muaj ib tug leak tshwm sim, lub rooj vag valve yuav tsum tau ceev ceev kaw nyob rau hauv ib tug luv luv lub sij hawm los mus tiv thaiv cov poob ntawm cov kua los yog roj los ntawm ua rau muaj teeb meem loj.

Thaum kawg, rooj vag li qub khaws cov kav dej kom nyab xeeb. Hauv qee qhov chaw uas muaj qhov hnyav hnyav, xws li cov nroj tsuag tshuaj, metallurgical refining, thiab lwm yam, lub rooj vag li qub tuaj yeem ua qhov pib rau kev nyab xeeb ntawm cov kav dej. Yog tias muaj kev txawv txav tshwm sim hauv cov kua dej hauv cov kav dej, lub qhov rooj valve tuaj yeem raug kaw cia li los yog manually txo qhov tshwm sim ntawm kev sib tsoo thiab tiv thaiv kev nyab xeeb ntawm tib neeg thiab khoom.
