Yuav ua li cas xaiv ib qho ntsuas kub tsawg ib puag ncig valve?

Kev xaiv ntawmRooj vag Li QubRau qhov tsawg-qhov chaw kub yuav tsum tau txiav txim siab los ntawm peb yam: Cov khoom muaj zog, kev tsim qauv, thiab qauv tsim qauv, raws li hauv qab no:

Khoom siv tawv tawv: qhov tseem ceeb ntawm tsawg-kub tsis yog brittleness

Hauv cov khoom siv tsawg-kub, cov ntaub ntawv yog nquag plam lawv cov tawv nqaij vim tias "tsawg-kub embrittlities", ua rau kev tawg ntawm rooj vag li qub. Thaum xaiv, qhov muaj feem ua ntej yuav tsum muab rau cov ntaub ntawv nrog cov khoom muaj hluav taws xob zoo heev:

Carbon Steel / Tsawg Alloy Steel: Haum rau nruab nrab thiab tsawg cov xwm txheej ntawm -20 ℃, xws li ≥ 27th, uas tuaj yeem ua tau kom tau raws cov kev lag luam dav dav.

Tus Hlau Stainless: Haum rau kev kub ntxhov qis tsawg kawg nkaus hauv qab -196 ℃ (tswj kev ua kua (haum rau ntub dej lossis corrosive tsawg-kub tshaj tawm-kub).

Nickel raws li cov neeg muaj npe, xws li Monel Alloy (NI cu alloy) thiab haum rau ultra-tsawg cov kab mob ib puag ncig) thiab tsis muaj kev pheej hmoo ntawm cov emborlittlement ntawm tsawg kub.

Sealing Performance: Txais ntawm Xoom Xau

Kev sealing kev ua tau ntawm tsawg-kubRooj vag Li Qubcuam ​​tshuam ncaj qha rau kev nyab xeeb system, thiab daim foos yuav tsum raug xaiv raws li cov haujlwm ua haujlwm:

Hlau Sealing: Hlau Coated Nrog Tooj Liab, Txhuas, Muaj Kev Ncaj Ncees, nrog kev ntseeg siab, nrog kev ntseeg tau yooj yim tab sis kev ua haujlwm siab yog.

Tsis yog xim hlau sealing: polytetrafluoroethylene (qhov kub tsis kam -200 ℃ ~ 260 ℃), haum rau cov xwm txheej tsis kam lees), haum rau nruab nrab thiab tsawg siab scenarios; Saj zawg zog graphite (kub tsis kam -200 ℃ ~ 1650 ℃), nrog ob qho siab qis, haum rau kev hloov siab thiab tsis muaj qhov kub ua haujlwm.

Bailrot Sealing: Hlau Stillows (xws li 316 Stainless Hlau Lwj), thaum tsis txhob ua kua rau ntawm lub valve qia thiab nruab nrab, txuas ntxiv lub neej pabcuam.

Tsim qauv txheej txheem: kev ua kom zoo rau kev hloov mus rau qhov kev kub ntxhov ntawm kub

Tsawg kubRooj vag Li QubYuav tsum tau txhawm rau txhawm rau kom mob txias thiab zam kev ntxhov siab los ntawm kev ua kom zoo tshaj plaws:

Tus caj dab ntev ntev: lub valve qia adopts ntev lub zog (feem ntau tuaj yeem thaiv cov neeg ua haujlwm txias, tiv thaiv kev tawm tsam sab nraud kom muaj cua sov

Kev tiv thaiv khov thiab rwb thaiv tsev: ib txheej txheem rwb thaiv tsev (xws li polyurethane ua npuas ncauj lossis pob zeb tsiaj) tuaj yeem ntsia tau sab nraud ntawm lub cev muaj peev xwm txias; Qee lub rooj vag lub rooj vag yog tsim nrog "ua tsis taus pa lub qhov" kom muaj kev tawm pov tseg kev nyab xeeb ntawm qhov qis zuj zus ntawm lub pob valve.

Anti Cov Dej Rauj Dov Tsim: lub rooj zaum lub rooj zaum txawv txav ntawm cov rauj ntws los ntawm kev hloov pauv nruab nrab, thiab rauj tej zaum yuav ua rau muaj kev puas tsuaj).
