Anti-zoo li qub valve yog ib lub valve tshwj xeeb tsim rau cov nplaim tawg thiab tawg. Nws cov haujlwm tseem ceeb yog tshem tawm kev pheej hmoo ntawm kev tawg tshwm sim los ntawm cov hluav taws xob hluav taws xob zoo li qub thiab ua kom muaj kev ntseeg tau ntawm kev sib khi thaum tua hluav taws thaum hluav taws. Nws cov ntsiab cai tseem ceeb thiab cov yam ntxwv muaj raws li hauv qab no:
1. Kev tiv thaiv txheej txheem qub
Lub caij nplooj ntoo hlav tawm ntawm qhov chaw txav ntawm lub valve (pob thiab lub cev) los tiv thaiv cov kab ke raug hluav taws xob thiab thaj chaw kom tiv thaiv qhov hluav taws xob tawm los ntawm kev tiv thaiv cov nruab nrab.
Cim Cim: Lub cev valve feem ntau yog cim nrog "raws li" (anti-anti-anti.
2. Kev tsim hluav taws
Adipts ib qho kev sib khi ob npaug:
Mos foob (xws li polytetrospaenoroethylene): kom ntseeg tau raws li kev ua haujlwm txhua hnub;
Kev txiav plaub hau (hlau rau hlau): Tom qab cov ntaub ntawv mos yog hlawv hauv qhov hluav taws kub, pob thiab hlau saum npoo av cia li ua ke kom muaj lub foob thiab cais cov nplaim taws.
Tus cim cim: lub cev valve yog cim nrog "FD" (hluav taws muaj kev nyab xeeb).
3. Muaj kev nyab xeeb ntxiv
Tsis Siv Neeg Siab Saws:
Thaum lub siab ntawm nruab nrab kab nruab nrab yog qhov txawv txav vim qhov kub thiab kub tau thawb lub rooj ntsuas kub kom tso tawm lub siab thiab tiv thaiv bursting.
Tsawg torque tsim:
Cov khoom txav txav siv cov ntaub ntawv ntawm tus kheej lubricating (xws li PTFE Composite cov ntaub ntawv) los txo kev ua haujlwm tiv thaiv.
4. Cov ntawv thov tseem ceeb
Feem ntau yog pab cov kev pheej hmoo siab:
Cov Roj Thauj Roj Thauj: Natural Gas, liquefied roj av, roj pipelines;
Petrochemical thiab lub zog: kev ua kom zoo dua, cov nroj tsuag tshuaj, roj cia thiab xa khoom xa tawm;
Cov xov xwm tshwj xeeb: oxygen, ethylene thiab lwm yam gases.
Cov lus qhia tseem ceeb: Cov pob tseem ceeb tsis tuaj yeem ua tau raws li qhov kev nyab xeeb ntawm cov xwm txheej nyab xeeb ntawm xws li cov xwm txheej, thiab hluav taws kub zoo li qub tuaj yeem ua rau muaj kev puas tsuaj loj.
5. Cov ntsiab lus tseem ceeb kom paub qhov txawv ntawm lub pob sib txawv
