Kuaj valve: Kos valve tseem hu ua ib-txoj kev valve lossis kos valve, nws txoj haujlwm yog los tiv thaiv qhov nruab nrab hauv cov raj xa dej Backflow.Lub valve hauv qab ntawm lub twj tso kua mis kaw cov dej kuj yog nyob rau hauv pawg tsis rov qab valve.Lub valve uas qhib los yog kaw ntawm nws tus kheej los ntawm qhov ntws thiab quab yuam ntawm qhov nruab nrab los tiv thaiv qhov nruab nrab ntawm ntws rov qab yog hu ua check valve.Kos li qub yog nyob rau hauv qeb ntawm tsis siv neeg li qub.Kos li qub feem ntau yog siv hauv cov kav dej uas qhov nruab nrab ntws mus rau hauv ib qho kev taw qhia, thiab tsuas yog tso cai rau qhov nruab nrab ntws mus rau hauv ib qho kev coj los tiv thaiv kev sib tsoo.Raws li cov qauv ntawm daim tshev valve, nws tuaj yeem muab faib ua peb hom: nqa daim tshev valve, viav vias kos valve thiab npauj npaim kos valve.Lift check li qub tuaj yeem muab faib ua ob hom: ntsug kos li qub thiab kab rov tav kos li qub.Lub viav vias kos valve tau muab faib ua peb hom: ib-nplooj kos valve, ob-ua haujlwm kos valve thiab ntau-nplooj kos valve.Npauj npaim check valve yog ncaj nraim los ntawm kos valve.Cov lus hais saum toj no tuaj yeem muab faib ua peb hom hauv daim ntawv txuas: threaded check valve, flanged check valve thiab welded check valve.
Lub installation ntawm lub check valve yuav tsum tau xyuam xim rau cov nram qab no: Tsis txhob ua rau lub check valve dais hnyav nyob rau hauv lub raj, thiab lub loj check valve yuav tsum tau kev txhawb nws tus kheej kom nws tsis cuam tshuam los ntawm lub siab generated los ntawm cov kav dej system.
Thaum txhim kho, xyuam xim rau cov kev taw qhia ntawm nruab nrab ntws yuav tsum ua raws li cov kev taw qhia ntawm lub xub pov npav los ntawm lub valve lub cev.
Lub lift-type ntsug check valve yuav tsum tau ntsia rau ntawm txoj kab ntsug.Lub tshuab nqa-hom kab rov tav nrov plig plawg kos valve yuav tsum tau nruab rau ntawm kab rov tav raj.
Kev ua haujlwm tseem ceeb ntawm daim tshev valve: Nominal siab lossis qib siab: PN1.0-16.0MPa, ANSI CLASS1 50-900, JIS 10-20K, nominal inch lossis caliber: DN15-900.
NPS 1/4-36, kev sib txuas txoj kev: flange, taub qab vuam, xov, qhov (socket) vuam, thiab lwm yam., siv tau kub: -196 ℃ -540 ℃, valve lub cev khoom: WCB.
ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (3041), CF8M (316), CF3M (316L), Ti, xaiv cov khoom sib txawv, kos li qub siv tau rau dej, chav dej, roj, nitric acid, acetic acid, oxidation kev sib deev media, urea thiab lwm yam xov xwm.
