Stainless hlau kev nyab xeeb li qub yog tsis siv neeg li qub thiab feem ntau yog siv nyob rau hauv boilers, siab hlab ntsha thiab pipelines los tswj lub siab kom tsis txhob siab tshaj tus nqi teev thiab ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv tus kheej kev nyab xeeb thiab cov khoom siv ua haujlwm. Nws yog ib qho cuab yeej tshwj xeeb tsim los tiv thaiv overpressure. Thaum lub siab nyob rau hauv cov khoom siv los yog cov kav dej nce mus rau qhov chaw pib, lub valve yuav sai sai thiab cia li qhib kom tso tawm tag nrho lub siab. Tom qab lub siab poob mus rau qhov chaw nyab xeeb, lub valve yuav cia li kaw kom ruaj khov ntawm cov khoom siv.
Qhov zoo
1.Strong Durability: Lub peev xwm ntawm cov khoom siv lossis cov khoom siv los tiv thaiv kev hnav, kev ntxhov siab, thiab kev puas tsuaj rau lub sijhawm ntev. Cov ntaub ntawv uas muaj zog muaj zog tuaj yeem tiv taus ib puag ncig hnyav, rov siv dua, thiab cov khoom siv dag zog tsis muaj degradation.
2.Good Corrosion Resistance: Corrosion resistance yog ib qho tseem ceeb nyob rau hauv ib puag ncig uas cov ntaub ntawv raug ya raws, tshuaj, los yog lwm yam corrosive agents. Cov ntaub ntawv zoo corrosion kuj tswj lawv cov qauv kev ncaj ncees thiab kev ua haujlwm dhau sijhawm.
3.High Precision: Precision yog hais txog qib ntawm qhov raug thiab rov ua dua tshiab hauv kev tsim khoom, kev ntsuas, lossis kev ua haujlwm. High precision yog qhov tseem ceeb nyob rau hauv daim ntawv thov uas nruj kam rau ua thiab cov specifications raws nraim yuav tsum tau.

Ntsej muag rau ntsej muag (kawg kawg): API 526
Kev Ntsuas thiab Kev Ntsuas: API 527
Installation tseem ceeb
Lub installation orientation yog ntsug, ua kom pom kev ua haujlwm zoo. Kev tawm dag zog tsis muaj zog yog qhov tseem ceeb los tiv thaiv kom tsis txhob muaj kev ntxhov siab. Ua ntej kev teeb tsa, cov txheej txheem kev sim ua kom zoo yuav tsum tau ua, nrog rau kev qhia tshwj xeeb ntawm kev txheeb xyuas qhov tseeb ntawm lub sealing mechanism.
Scope ntawm daim ntawv thov
Kev nyab xeeb li qub yog cov khoom siv tseem ceeb ua haujlwm hauv cov roj av, cov kav dej kub kub, thiab cov kav dej sib txawv.
Txoj Cai Kev Ua Haujlwm
1.Spring los yog Nyhav: Kev nyab xeeb li qub feem ntau suav nrog lub caij nplooj ntoos hlav-loaded mechanism los yog lub luj-loaded. Cov tivthaiv no yog calibrated los ua ib tug quab yuam raws li qhov xav tau qhib siab.
2.Set Pressure: Lub teeb siab yog qhov ntsuas qhov siab ntawm qhov kev ruaj ntseg valve yog tsim los qhib thiab pib relieving siab. Tus nqi no yog txiav txim siab raws li cov txheej txheem kev ua haujlwm thiab cov kev xav tau ntawm kev nyab xeeb.
3.Valve Disc los yog Lub Rooj: Lub valve disc yog tuav tawm tsam lub rooj zaum valve los ntawm lub caij nplooj ntoos hlav lossis lub cev hnyav. Thaum lub siab nyob rau hauv lub system tshaj lub teeb siab, nws overcomes lub quab yuam exerted los ntawm lub caij nplooj ntoos hlav los yog qhov hnyav, ua rau lub valve disc nqa tawm lub rooj.
4.Pressure Relief: Raws li lub valve disc lifts, nws tsim ib qho qhib los ntawm kev uas cov kua los yog roj muaj peev xwm khiav tawm. Txoj kev tso tawm no tso cai rau lub siab tshaj plaws kom muaj kev nyab xeeb tawm ntawm lub cev, tiv thaiv kev kub ntxhov ntau dhau.
5.Closure Mechanism: Thaum lub siab txo qis mus rau theem kev nyab xeeb, lub caij nplooj ntoos hlav lossis lub cev hnyav rov ua dua lub valve disc, kaw txoj hauv kev tawm. Qhov no restores lub system mus rau nws ib txwm ua hauj lwm tej yam kev mob.
