Qhov zoo ntawm Peb Cov Tsis Txaus Ntsig Nroj Tsuag Sealing Gate Valve
1) Lub foob sab sauv ntawm lub valve yog kaw los ntawm peb "O"-zoo li cov roj hmab sealing rings, thiab ob sab "O"-zoo li tus roj hmab sealing nplhaib tuaj yeem hloov tau yam tsis tso dej.
2) Lub cev lub cev thiab lub kaus mom txais yuav "O" hom roj hmab sealing nplhaib qauv, uas tuaj yeem paub txog tus kheej sealing.
3) Thaum lub valve qhib tag nrho, lub valve phaj siab dua li txoj kab uas hla ntawm lub valve, hauv qab ntawm lub valve lub cev yog du yam tsis muaj qhov rooj zawv zawg, thiab qhov ntws tsis kam coefficient yog me me, uas zam qhov tshwm sim ntawm lub phaj valve. tsis nruj nreem kaw vim cov khib nyiab thaiv lub gasket.
4) Lub valve qia txiv ntoo thiab rooj vag phaj txuas nrog T-slot, uas muaj lub zog siab, thiab radial kev sib txhuam quab yuam ntawm lub phaj valve thiab lub valve lub cev yog me me, thiab kev pab cuam lub neej ntev.
5) Kev tiv thaiv xeb thiab tiv thaiv corrosion txais electrostatic txau ntawm cov tshuaj tsis muaj tshuaj lom epoxy resin kub-melt solidification hmoov.Cov hmoov muaj WRAS thiab NSF ntawv pov thawj, uas tshem tawm cov pa phem thib ob rau cov dej zoo thiab ua rau cov dej ntshiab ntau dua.
