Siv rau hauv kev kub siab chav, kua, catalytic hloov kho, hydrocrackers, thiab lwm yam kev thov, JLPV forged steel siab foob pob valve yog tsim. Boiler, roj av, tshuaj lom neeg, metallurgical, lub zog, thiab kev siv fais fab-kev lag luam tseem ceeb tsuas yog qee qhov kev lag luam uas nquag siv JLPV forged steel check li qub. Pressure Seal Check Valve tseem muaj ntau yam kev lag luam muaj kev ruaj ntseg, tsis muaj qhov tsis muaj qhov tsis muaj qhov txwv tsis pub nyob hauv lub ntiaj teb xav tau ntawm Kev Kub Siab, Kub Kub Valve daim ntawv thov. Cov unidirectional li qub no tiv thaiv kev ntws los ntawm qhov sib txawv. Cov no ua haujlwm zoo nyob rau hauv cov chaw uas muaj qhov nrawm nrawm. Txawm hais tias cov tshev valve tuaj yeem haum rau hauv cov kav dej ntsug, lawv feem ntau ua rau cov kab rov tav ntws, qhov ntws yuav tsum mus rau hauv qab lub disc thiab yuav tsum tau nce siab. Lub tswv yim tseem ceeb tom qab lub siab foob li qub yog tias thaum lub hau npog thawj rub-up bolts tau nruj, lub hau nws tus kheej muab lub siab seal gasket rau lub cev. Lub kaw lus siab pab yog tom qab ntawd siv los siv ntau lub siab los kaw lub gasket. Yog li ntawd, qhov ua tau los ntawm lub cev / lub kaus mom sib koom ua ke txo qis thaum lub zog siab nce.
Qhov ntau ntawm JLPV Forged steel li qub tsim yog raws li hauv qab no:
1.Size: 1/2 "mus rau 2" DN15 rau DN1200
2.Pressure: Chav Kawm 800lb txog 2500lb PN100-PN420
