Kev tuav rooj vag li qub

Kev tuav rooj vag Valve yog lub valve uas tswj hwm cov dej ntws los ntawm kev ua haujlwm ntawm phau ntawv. Nws qhib thiab kaw ntu yog rooj vag. Qhov kev taw qhia txav ntawm lub rooj vag yog sib tshuam rau cov kev taw qhia ntawm cov kua dej. Nws tsuas yog ua tiav tag nrho qhib lossis tag nrho kaw ntawm nruab nrab thiab tsis tuaj yeem siv rau kev tswj hwm kev cai lossis kev thaiv.

Cov qauv tseem ceeb thiab cov khoom siv
Cheebtsam tseem ceeb:
Lub cev valve: tus qauv tseem ceeb uas haum cov kua dej. Cov khoom yuav tsum tau yoog raws li cov yam ntxwv nruab nrab.
Rooj vag: Nws tau muab faib ua rooj vag rigid (sib txuam ua ke) thiab Elastic Gate (me ntsis deformable). Qee cov qauv coj los yuav npaj ob lub rooj vag kauj ruam mus rau kev txhim kho kev sib khi.
Sealing nto:
Hlau foob: xws li Surfacing Carbide (Stellite 6), tiv taus qhov siab kub thiab particle yaig.
Tsis yog-hlau foob: xws li polytetrosraTrene (PTFE), haum rau cov kua dej kom huv.
Tsav Ntaus Khoom: HANDWEEL, VALVE LUJ THIAB VALIDE KHWV, uas tsav lub rooj vag kom sawv thiab poob los ntawm kev sib hloov.

Ua Haujlwm Cov Ntsiab Cai
Qhib thiab kaw txheej txheem:
Qhib: tig mus rau tes ua hauj lwm raws li lub rooj vag kom sawv ntsug, ua tau los ntawm cov channel txaus, thiab tsim ib lub channel unobstructed.
Kaw: Tig lub Handwwheel counterclockwise, lub rooj vag yog nias cia kom haum rau lub rooj zaum kom tau salloff.
Sealing tshuab:
Npoo Foob: lub rooj vag ua ib lub npoo ntawm Wedge (feem ntau 50 degree) nrog lub rooj valve, thiab nruab nrab lub zog pab txhim kho cov nyhuv seading.
Elastic them nyiaj tuaj yeem ua tau me ntsis kom tsis quav ntsej los ua qhov tsis raug lossis hnav thiab tswj kev ntseeg tau.
