Cryogenic Pob Valve Stem Foob

Hauv kev ua haujlwm LNG, li qub tuaj yeem ntsib qhov kub thiab txias hauv qab -320 F (-196 C) thiab siab tshaj 750 phaus ib square inch (psi). Lawv kuj raug hloov pauv raws sijhawm nyob rau hauv qhov kub thiab txias hu ua "thermal cycling," uas tuaj yeem ua rau cov khoom lag luam nthuav dav ntxiv nrog rau kev txo qis thiab cov khoom hnyav. Cov yam tseem ceeb no ua rau txhim khu kev qha, lub sij hawm ntev valve ua haujlwm ib qho kev sib tw engineering.

Qhuav Taw Qhia

Kev ua tau zoo, txhim khu kev qha valve yog qhov tseem ceeb rau kev ua tiav ntawm kev ua haujlwm LNG / CNG, thiab cov ntsaws ruaj ruaj ua lub luag haujlwm tseem ceeb hauv kev ua kom lub valve nce thiab khiav. Tab sis lawv txoj hauj lwm nyuaj los ntawm cov kev xav tau kev pab cuam.

Sealing Success Factors:

Txhawm rau muab kev tiv thaiv zoo tshaj tiv thaiv cov dej hauv cov kua dej cryogenic rau LNG, cov ntsaws ruaj ruaj yuav tsum muaj:

1. Cov khoom siv tsho uas tiv taus cua sov caij tsheb kauj vab

2. Ib qho energizer los them rau qhov shrinkage

3. Anti-extrusion di ncauj geometry

Nrog rau kev tsim thiab tsim cov khoom tsim nyog, lawv tuaj yeem muab kev pabcuam sealing zoo dua li lwm cov thev naus laus zis, xws li cov khoom siv hlau, cov ntsaws ruaj ruaj elastomeric thiab cov ntim khoom-tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov dynamic. Qhov tseeb, txoj cai polymer seals tuaj yeem pab cov engineers ua tiav qib tshiab ntawm kev ua haujlwm valve.

Kev sib khi ntawm qhov kub thiab txias cryogenic muaj nws tus kheej cov teeb meem tshwj xeeb. XLONG muaj ntau yam kev daws teeb meem rau cov ntawv thov kev sib khi. Cryogenic cov ntsaws ruaj ruaj yuav tsum tau tsim kev txawj ntse los ntawm kev sib txuas cov khoom zoo, kev teeb tsa lub foob, thiab lub caij nplooj ntoos hlav energizer kom kov yeej qhov kev hloov pauv ntawm txhua qhov sib txuas.

HS series lub caij nplooj ntoos hlav energized foob tuaj yeem ua haujlwm nyob rau hauv ib puag ncig ntawm - 196 degree qis kub thiab corrosive tshuaj rau lub sijhawm ntev. Thaum lub kaw lus siab yog xoom, lub caij nplooj ntoos hlav muab thawj lub siab ua ntej. Thaum lub kaw lus siab nce, U-shaped kab noj hniav yog ntim nrog lub siab nruab nrab kom lub di ncauj ze rau ntawm lub tog raj kheej phab ntsa. Nyob rau hauv txoj kev no, nws ua kom ntseeg tau tias lub foob yeej ib txwm muaj kev sib khi zoo nyob rau hauv tag nrho cov txheej txheem ntawm kev hloov siab, thiab lub caij nplooj ntoos hlav tuaj yeem xaiv 'U', 'V' thiab 'O' hom raws li qhov chaw sib txawv.

Spring energized foob:

HS foob yog ua los ntawm lub caij nplooj ntoos hlav helical thiab lub tsho polymer, uas yog siv los ua Flange sab nrauv lub ntsej muag.

Lub tsho polymer cov khoom muaj xws li PTFE, TFM, PCTFE, thiab lwm yam.

Lub helical lub caij nplooj ntoos hlav cov khoom siv xws li Stainless Hlau, Elgiloy, Hast Alloy, thiab lwm yam.

Thaum lub siab ntau dua 900LBS, yuav tsum muaj lub nplhaib tiv thaiv extrusion;

Qhov zoo:

1. Cov khoom sib xyaw ua ke dhau API 6A FF / HH Immersion Testing;
2. Yooj yim installation;
3. NACE pom zoo energizers muaj rau kev siv roj thiab roj;
4. Ntau yam ntawm cov hlaws dai thiab txoj kab uas hla muaj, tshwj xeeb tshaj yog rau cov hlaws loj;
5. Zoo sealing kev ua tau zoo ntawm qhov kub thiab txias;
6. Bi directional tsim ua haujlwm zoo dua hauv daim ntawv thov siab.
