Kuaj valve: Kos lub valve, tseem hu ua ib-txoj kev valve lossis kos valve, yog siv los tiv thaiv qhov nruab nrab hauv cov kav dej los ntawm ntws rov qab.Lub hauv qab valve rau lub twj tso kua mis nqus dej thiab kaw kuj yog nyob rau hauv qeb kos valve.Lub valve uas tso siab rau qhov ntws thiab quab yuam ntawm qhov nruab nrab kom qhib lossis kaw nws tus kheej, txhawm rau 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 rau hauv cov kav dej nrog unidirectional ntws ntawm cov xov xwm, cia tsuas yog ib qho kev taw qhia ntawm cov xov xwm ntws los tiv thaiv cov xwm txheej.Kos li qub tuaj yeem muab faib ua peb hom raws li lawv cov qauv: nqa daim tshev li qub, viav vias kos li qub, thiab npauj npaim kos li qub.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 li qub tau muab faib ua peb hom: ib qho disc kos li qub, ob lub disc kos li qub, thiab ntau daim ntawv kos li qub.Npauj Npaim kos li qub yog ncaj qha los ntawm cov kos li qub, thiab cov hom kev kos li qub tuaj yeem muab faib ua peb hom kev sib txuas: threaded check li qub, flange check li qub, thiab welded check li qub.
Lub installation ntawm check li qub yuav tsum tau xyuam xim rau cov nram qab no teeb meem:
1. Tsis txhob tso cai rau lub pob valve los nqa qhov hnyav hauv cov kav dej.Cov tshev loj loj yuav tsum tau txais kev txhawb nqa ntawm nws tus kheej los tiv thaiv lawv los ntawm kev cuam tshuam los ntawm lub siab tsim los ntawm cov kav dej.
2. Thaum lub sij hawm installation, xyuam xim rau cov kev taw qhia ntawm nruab nrab ntws uas yuav tsum tau raws li cov xub taw qhia ntawm lub valve lub cev.
3. Nqa hom ntsug disc kos li qub yuav tsum tau muab ntsia rau ntawm cov kav dej ntsug.
4. Lub lifting hom kab rov tav disc kos valve yuav tsum tau ntsia rau ntawm kab rov tav raj.
Cov kev ua haujlwm tseem ceeb ntawm cov tshev valve:
Nominal siab lossis siab siab: PN1.0-16.0MPa, ANSI Class150-900, JIS 10-20K, nominal txoj kab uas hla los yog txoj kab uas hla: DN15 ~ 900, NPS 1/4-36, kev sib txuas txoj kev: flange, taub qab vuam, xov, qhov (socket) welding, thiab lwm yam., siv tau kub: -196 ℃ ~ 540 ℃, valve lub cev khoom: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti.Los ntawm kev xaiv cov khoom sib txawv, daim tshev valve tuaj yeem tsim nyog rau ntau yam xov xwm xws li dej, chav dej, roj, nitric acid, acetic acid, oxidizing media, urea, thiab lwm yam.
