Khoom Description
Lub ntiaj teb valve yog hais txog lub valve uas cov tswv cuab kaw (valve disc) txav mus raws qhov nruab nrab ntawm lub rooj zaum valve.
Stainless hlau nres valve yog hom nres valve. Nws muaj cov kev xav tau siab ntawm cov khoom siv ntawm lub cev valve. Feem ntau, muaj ntau yam khoom siv xws li 301.304.316. Nws yog dav siv nyob rau hauv kev lag luam tshuaj, shipbuilding, tshuaj, zaub mov machinery thiab lwm yam lag luam. Stainless hlau nres li qub tau muab faib ua phau ntawv stainless hlau nres li qub, pneumatic stainless hlau nres li qub, thiab hluav taws xob stainless hlau nres li qub.

Cov yam ntxwv ntawm Globe Valve
(1) Cov qauv yog yooj yim dua li ntawm cov rooj vag li qub, thiab nws yooj yim dua los tsim thiab tswj.
(2) Lub sealing nto tsis yooj yim rau hnav thiab khawb, thiab muaj kev sib khi zoo. Tsis muaj tus txheeb ze zawv zawg ntawm lub valve disc thiab lub valve lub cev sealing nto thaum qhib thiab kaw, yog li qhov hnav thiab khawb tsis hnyav, kev sib khi ua haujlwm zoo, thiab kev pabcuam lub neej ntev.
(3) Thaum qhib thiab kaw, lub valve disc stroke me me, yog li qhov siab ntawm qhov nres valve yog me dua li ntawm lub rooj vag valve, tab sis cov txheej txheem ntev ntev dua li ntawm lub rooj vag valve.
(4) Qhov qhib thiab kaw lub zog yog qhov loj, qhov qhib thiab kaw yog qhov nyuaj, thiab lub sijhawm qhib thiab kaw yog ntev.
(5) Cov dej tsis kam yog loj. Vim tias qhov nruab nrab channel hauv lub cev lub cev yog tortuous, cov dej tsis kam yog loj thiab lub zog noj yog loj.
(6) Nruab nrab ntws kev taw qhia: Thaum lub nominal siab PN tsawg dua los yog sib npaug rau 16MPa, downstream ntws feem ntau yog siv, thiab qhov nruab nrab ntws los ntawm lub hauv qab ntawm lub valve disc; Thaum lub nominal siab PN siab tshaj los yog sib npaug rau 20MPa, countercurrent flow feem ntau yog siv, thiab qhov nruab nrab ntws downwards los ntawm sab saum toj ntawm lub valve disc. Txhawm rau txhim kho kev ua haujlwm sealing. Thaum siv, qhov nruab nrab nres valve tsuas tuaj yeem ntws mus rau hauv ib qho kev taw qhia thiab tsis tuaj yeem hloov txoj kev khiav.
(7) Lub valve disc feem ntau eroded thaum qhib tag nrho.
