Lub rooj vag hluav taws xob hloov hluav taws xob valve yog lub valve tseem ceeb uas tau optimide rau ntawm lub hauv paus ntawm cov tsoos rigid ib lub rooj vag. Nws cov qauv feature yog kom ua tiav cov kev hloov kho tus kheej kom zoo thiab muab khi rau kev them tus kheej ua haujlwm los ntawm kev tsim tshwj xeeb rau lub rooj vag tshwj xeeb. Lub ntsiab nta thiab muaj pes tsawg leeg yog raws li hauv qab no:
1. Cov Txheej Txheem Qauv Tshwj Xeeb
Elastic Rooj Hlau Tsim
Lub rooj vag wedge yog ua tiav nrog lub qhov zawj hauv nruab nrab hauv nruab nrab, thiab tsuas yog chaw sib txuas hauv Central yog khaws cia ua ib tus qauv sib txawv.
Thaum kaw, qhov zawj muaj compressed thiab sib cog lus, muab kev sib cog lus, muab kev sib cog lus rau lub kaum sab xis ntawm lub rooj zaum thiab lub rooj vag.
Anti-stuck Mechanism
Thaum lub hauv paus valve nthuav dav nyob rau hauv cov kev mob siab, elastic lub rooj sib haum yuav deform zoo kom tsis txhob daig nyob rau hauv lub rooj valve vim nthuav.
Txhim Kho Cov Foob
Elastic Preload + Nruab Nrab Nruab Nrab Ob Chav Ua Rau Tas Bidirectional xoom
2. Cov ntsiab lus tseem ceeb muaj pes tsawg leeg
Elastic Wderge Rooj vag
Lub cev tseem ceeb yog cov npoo-puab tus hlau stainless hlau casting (xws li WCB, 304SS), thiab qhov tob ntawm lub zeem muag annosity yog xam tau kom ntseeg tau tias muaj tus nqi loj heev.
Valve Lem Txuas System
Hauv qab qhov kawg ntawm lub valve ci txuas nrog lub rooj vag los ntawm kev zawj inverted t-puab, tso cai me ntsis viav vias kom yoog raws lub kaum sab xis.
VALVE LUB ROOJ CIM
Overlaying carbide lossis embedded PTFE Sealing nplhaib (corrosion-resistant hom) cov qauv sib khi sib khi khi nrog lub rooj vag elastic.
Valve Npog Thiab Stuffing Box
Txuas txuas rau lub valve npog tsim teeb tsa cov chaw tso tseg rau thermal nthuav ntawm lub rooj vag;
Saj zawg zog graphite packing ua kom muaj zog dynamic sealing ntawm lub zog valve.
3. Cov ntsiab lus kev ua tau zoo
| Yam zoo | Tus nqi |
|---|---|
| Siab kub yoog | Cov kev txwv sab saud ntawm kev ua haujlwm kub yog 425℃(cov hom pa), zam kev nthuav dav thiab stagnation |
| Loob kev cia siab | Kev them nqi elastic rau lub rooj zaum, txuas lub neej |
| Tsawg khiav hauj lwm torque | Elastic tiv toj txo cov txhuam hniav, thiab qhib thiab kaw lub zog yog ntau dua 30% qis dua li ntawm lub rooj vag txhav |
4. Daim Ntawv Thov
Kev kub siab chav dej: Chav dej tseem ceeb ntawm cov hluav taws xob thermal fais fab (siab tsawg dua los yog sib npaug rau 40mpa);
Petrochemical tsob nroj: Cov roj roj kub tshiab, catalytic cracking chav tsev (corrosion-resistant ob sab ntaub ntawv yuav tsum tau);
Kev ua haujlwm ntawm kev ua haujlwm hloov pauv: pipelines nrog ntau zaus / siab hloov, vam khom tus qauv ywj pheej kom muaj kev sib khi.
Kev ua haujlwm thiab txij nkawm cov ntsiab lus
Kev tswj hwm: Yuav tsum muab ntsia cov kab ntsug (qia tig), txwv tsis pub tus kws lij choj loj yuav swb;
Hloov qhov txwv: Tsuas yog siv rau tag nrho cov kev qhib / tag nrho ze, throtling kev ua haujlwm yog nruj me ntsis txwv (kom tsis txhob zawj yaig);
Kev Txij Nkawm Qhia Txog: Nquag xyuas seb lub GATE Groove tau tawg lossis tawg yooj yim.
