1. Tsawg-Kub Media (-100 degree rau 0 degree )
Hauv kev lag luam xws li kev ua cov pa roj ntsha thiab cov tshuab cryogenic, cov xov xwm kub tsis tshua muaj peev xwm ncav cuag tsawg li -100 degree . Valves nyob rau hauv xws li ib puag ncig yuav tsum tau tiv thaiv kom khov, tiv taus txias txias, thiab xyuas kom nruj sealing. Cov ntaub ntawv zoo li stainless hlau, bronze, thiab tshwj xeeb alloys feem ntau yog siv los tswj kev yoog raws thiab tiv thaiv embrittlement.
Pom zoo li qub:
- Cryogenic Pob Valves: Nrog txuas ntxiv bonnets los xyuas kom meej cov rwb thaiv tsev kom zoo thiab tswj kev ua haujlwm.
- Globe Valves: Haum rau kev tswj cov dej ntws hauv cov txheej txheem qis.
2. Nruab nrab-Tsub Media (0 degree txog 200 degree)
Rau cov txheej txheem uas muaj dej, chav dej, thiab qee cov roj, qhov nruab nrab kub nruab nrab ntawm 0 degree thiab 200 degree . Cov ntsuas kub no muaj nyob rau hauv cov chaw kho dej, cov chaw siv hluav taws xob, thiab cov tshuab cua sov. Cov li qub siv ntawm no yuav tsum sib npaug ntawm kev ua haujlwm ntev thiab kev ua haujlwm yam tsis muaj cov khoom tshwj xeeb.
Pom zoo li qub:
- Rooj vag Valves: Zoo tagnrho rau kev cais tawm hauv cov tshuab xws li cov kav dej.
- Npauj Npaim Valves: Siv nyob rau hauv HVAC thiab dej systems vim lawv cov nqi-zoo thiab yooj yim ntawm installation.
- Pob Valves: Muaj kev ntseeg siab rau kev tswj-tawm hauv dej thiab roj siv.
3. High-temperature Media (200 degree txog 500 degree)
Nyob rau hauv daim ntawv thov xws li petrochemical ua thiab refining, high-temperature media feem ntau ncav cuag kub ntawm 200 degree thiab 500 degree. Valves ntawm no yuav tsum tiv thaiv oxidation, thermal expansion, thiab kev hloov pauv siab, ua kom lub cev ruaj khov mus ntev.
Pom zoo li qub:
- Kev Ua Haujlwm Siab Pob Valves: Cov li qub no feem ntau yog ua los ntawm cov hlau tsis muaj steel lossis Inconel los tuav cov cua sov thiab siab.
- Hlau Seated Npauj Npaim Valves: Haum rau kev siv chav ua noj, muab cov cua sov ua haujlwm thiab cov xau qis.
- Globe Valves: Feem ntau siv nyob rau hauv cov kev pab cuam throttling rau chav thiab cov kua dej kub.
4. Extreme-Temperature Media (Tshaj 500 degree)
Cov ntawv thov tshwj xeeb, xws li cov tshuab hluav taws xob lossis cov tshuab hluav taws xob superheated hauv cov chaw tsim hluav taws xob, yuav muaj qhov kub siab tshaj 500 degree. Ntawm cov theem no, kev xaiv cov khoom siv tseem ceeb, nrog cov alloys xws li Hastelloy lossis titanium kom ntseeg tau tias lub valve ua haujlwm tsis muaj deformation lossis tsis ua haujlwm.
Pom zoo li qub:
- Pressure-Sealed Gate Valves: Siv nyob rau hauv high-pressure, high-temperature daim ntaub ntawv zoo li superheated chav.
- Hlau Seated Pob Valves: Tsim los rau huab cua kub ib puag ncig uas cov rooj zaum mos yuav degrade.
- High-temperature Control Valves: Tshwj xeeb engineered los tswj kev ntws thiab siab hauv qhov xav tau ib puag ncig.
Yam tseem ceeb rau Valve xaiv raws li qhov kub thiab txias
- Khoom siv: Valves ua los ntawm stainless hlau, tshwj xeeb alloys, los yog cam khwb cia hlau muab lub zog thiab lub neej ntev ntawm qhov sib txawv ntawm qhov kub thiab txias.
- Sealing Mechanism: Rau cov kev siv kub kub, cov hlau ntsaws ruaj ruaj zoo dua cov ntsaws ruaj ruaj, uas yuav degrade raws sij hawm.
- Thermal Expansion: Kub kub ua rau cov ntaub ntawv nthuav dav, yog li xaiv cov khoom siv uas tiv thaiv kev nthuav dav yog qhov tseem ceeb.
- Kev ntsuas siab: Kev kub siab dua feem ntau sib haum rau siab dua, yog li cov valve yuav tsum tau ntsuas raws li kom tsis txhob xau lossis tsis ua haujlwm.
Xaus
Xaiv txoj cai valve raws li qhov kub thiab txias ntawm cov khoom nruab nrab yog qhov tseem ceeb rau kev nyab xeeb, kev ua tau zoo, thiab kev ua haujlwm ntev. Los ntawm cov txheej txheem cryogenic mus rau superheated chav, txhua qhov ntsuas kub xav tau cov ntaub ntawv tshwj xeeb thiab cov qauv tsim kom muaj kev ua haujlwm zoo. Los ntawm kev nkag siab txog qhov kub thiab txias ntawm koj cov txheej txheem kev lag luam, koj tuaj yeem ua kom lub valve koj xaiv yuav tiv taus cov xwm txheej, txhim kho kev ua haujlwm zoo, thiab txo cov kev xav tau ntawm kev saib xyuas.
