Kos lub valve, lub npe hu ua ib-txoj kev valve, kos valve, rov qab siab valve, hom valve no tau qhib thiab kaw los ntawm lub zog tsim los ntawm qhov ntws ntawm qhov nruab nrab nws tus kheej hauv cov kav dej, thiab belongs rau lub valve tsis siv neeg. Kev ua haujlwm ntawm cov tshev valve yog los tiv thaiv qhov rov qab ntawm qhov nruab nrab, qhov rov qab tig ntawm lub twj tso kua mis thiab nws lub cev muaj zog, thiab kev tawm ntawm qhov nruab nrab hauv lub thawv.
Dual disc check valvekuj hu ua wafer hom npauj npaim kos valve. Hom kev kuaj vavle no muaj qhov ua tau zoo tsis rov qab los, kev nyab xeeb thiab kev ntseeg tau, me me ntws tsis kam coefficient. Ob-qhov rooj kos valve yog ib hom kev kos valve. Los ntawm kev xaiv cov khoom sib txawv, lub wafer check valve tuaj yeem siv rau hauv dej, chav dej, roj hauv petrochemical, metallurgy, hluav taws xob fais fab, lub teeb kev lag luam, khoom noj khoom haus thiab lwm yam lag luam. , nitric acid, acetic acid, muaj zog oxidizing nruab nrab thiab urea thiab lwm yam xov xwm.
Lub check valve txais yuav hom wafer, lub phaj npauj npaim yog ob lub voj voog, thiab lub caij nplooj ntoos hlav yog siv rau kev yuam kom rov pib dua. Lub sealing nto tuaj yeem welded nrog cov khoom hnav-tiv taus lossis lined nrog roj hmab.Lub phaj npauj npaim, thaum ntws rov qab, kaw lub valve los ntawm lub caij nplooj ntoos hlav quab yuam thiab nruab nrab siab. Hom npauj npaim kos valve no feem ntau yog cov qauv wafer, me me, lub teeb hauv qhov hnyav, txhim khu kev qha sealing, thiab tuaj yeem ntsia tau rau hauv cov kav dej kab rov tav thiab ntsug.
