Muaj cov hlau hauv qab kom cais lub valve qia los ntawm cov kua dej, tiv thaiv kev tawm sab nraud. Nyob rau hauv ib txoj haujlwm tsim hluav taws xob nuclear, txoj hlua khi valve ua haujlwm tsis tu ncua hauv xov tooj cua tshaj tawm rau 10 xyoo yam tsis muaj qhov xau, txhim khu kev nyab xeeb.
2.2 Tuag Volume thiab Residual Gas Control
Lub ntim tuag ntawm VCR valve (qhov chaw nruab nrab ntawm lub taub hau lub taub hau thiab lub rooj zaum lub valve tsis nyob ntawm cov kua dej) yuav tsum tsawg li sai tau kom txo tau qhov cuam tshuam ntawm cov khoom seem ntawm cov txheej txheem:
Ncaj-los ntawm cov qauv:
Lub ntim tuag tsawg dua li ib nrab ntawm cov yoj raj valve, ua kom yooj yim tshem tawm cov roj seem. Lub Hoobkas semiconductor tau txais kev ncaj nraim -los ntawm VCR valve thiab txo lub sijhawm hloov ntawm cov pa roj tshwj xeeb los ntawm 30 vib nas this mus rau 10 vib nas this, yog li txhim kho kev tsim khoom.
Tsis muaj kev sib txhuam tsim qauv:
Tsis muaj kev sib txhuam ntawm lub taub hau valve thiab lub rooj zaum valve, tiv thaiv cov khoom hlau los ntawm kev ntog tawm thiab ua paug rau qhov nruab nrab. Ib lub tuam txhab biopharmaceutical txo cov kab mob sib kis hauv cov tshuaj tiv thaiv mus rau 0.1 ppm los ntawm kev siv cov kev sib txhuam tsis muaj VCR valve.
III. Siab thiab Kub Ntau Yam: Los ntawm cov xwm txheej txheem mus rau qhov chaw huab cua
3.1 Siab Ntau thiab Siab Ua Haujlwm Muaj Peev Xwm
Lub peev xwm ua haujlwm siab ntawm VCR valve xav tau los npog qhov siab tshaj plaws ua haujlwm siab ntawm lub cev thiab tawm ntawm kev nyab xeeb:
Tsawg- daim ntawv thov siab (<1 MPa):
Qhov kev xaiv 316L stainless hlau valve lub cev yog tus nqi - zoo thiab yooj yim los tswj. Hauv chav kuaj roj kav, 1/4 "VCR valve ua haujlwm ruaj khov ntawm 0.5 MPa siab rau 5 xyoos.
High-pressure application (>10 MPa):
Yuav tsum muaj Hastelloy lossis Inconel alloy valve lub cev. Hauv qhov tob -kev tshawb nrhiav dej hiav txwv, qhov siab - siab VCR valve tswj kev sib khi ntawm cov dej siab ntawm 30 MPa, ua kom muaj kev nyab xeeb ntawm cov khoom siv.
3.2 Kub ntau thiab cov khoom siv thermal stability
VCR valve yuav tsum tau hloov mus rau qhov kev ua haujlwm kub kom tsis txhob muaj cov khoom siv thermal expansion lossis contraction ua rau to:
High-temperature environment (>200 degree):
Xaiv 317L stainless hlau lossis Inconel alloy. Nyob rau hauv lub siab - kub cracking ntaus ntawv ntawm ib tug petrochemical enterprise, lub 317L valve lub cev tseem structurally ruaj khov ntawm 450℃thiab muaj ib tug lifespan ntawm 8 xyoo.
Tsawg- qhov kub thiab txias (<-50℃):
Siv Vespel lossis PTFE lub rooj zaum. Hauv cov kua nitrogen cia tank, Vespel valve lub rooj tseem tuaj yeem ua haujlwm yooj yim ntawm -196 degree, ua kom muaj kev nyab xeeb.

Siv lub torque wrench kom ceev cov txiv ntseej rau tus qauv qhov tseem ceeb (piv txwv li, nickel gaskets nruj los ntawm 1/8 tig, tooj liab gaskets los ntawm 1/4 tig). Nyob rau hauv ib tug tej yam semiconductor Hoobkas, nruj nruj heev ua rau lub gaskets deform thiab tus nqi xau tshaj tus qauv los ntawm 10 zaug. Qhov teeb meem tau daws los ntawm cov txheej txheem installation txheej txheem.
Marking Alignment:
Thaum lub sij hawm installation, kos cov kab ncaj nraim ntawm cov txiv ntoo hauv thiab sab nraud. Tom qab kev teeb tsa, xyuas lub kaum sab xis ntawm cov kab kos (rau cov hlau tsis muaj steel / npib tsib xee gaskets, nws yog 45 degrees, rau tooj liab gaskets, nws yog 90 degrees) kom nruj nruj.
4.2 Kev Saib Xyuas Tsis tu ncua thiab kev tswj lub neej
Kev saib xyuas ntawm VCR li qub yuav tsum tau npaj raws li kev ua haujlwm kom ntev lawv lub neej kev pabcuam:
Gasket Hloov:
Tom qab nquag disassembly, cov gaskets tshiab yuav tsum tau hloov kom tsis txhob muaj cov dej xau los ntawm kev siv dua. Ntawm cov nroj tsuag tshuaj, gaskets yog hloov txhua txhua 3 zaug ntawm disassembly thiab installation, thiab tus nqi xau yog tswj nyob rau hauv 0.5%.
Leak Detection:
Kev kuaj pom tsis tu ncua yog nqa tawm siv lub helium mass spectrometer. Ntawm lub chaw tsim hluav taws xob nuclear, kev xau thaum ntxov tau kuaj pom los ntawm kev ntsuas cov pa xau txhua hli, tiv thaiv kev sib tsoo.
V. Xaiv Case: Los ntawm Kev Tshawb Fawb Txog Kev Tshawb Fawb Txog Kev Ua Haujlwm Zoo
