Nta ntawm forged steel xov / qhov (socket) welding ntiaj teb valve
1. Nws muaj cov qauv compact, zoo nkauj tsos thiab txo qis channel. Cov yam ntxwv ntawm tus qauv: BB lossis WB;
2. Lub sealing nto yog ua los ntawm alloy steel los yog cemented carbide. Qhov sib txuam ntawm cov ntaub ntawv sib khi yog tsim nyog thiab kev pabcuam lub neej ntev;
3. Lub valve disc yog conical, thiab lub valve qia yog muab nrog inverted foob, nrog zoo sealing kev ua tau zoo. Qhov saum npoo ntawm lub qia valve yog nitrided, uas muaj qhov zoo corrosion kuj thiab kev sib txhuam tsis kam. Cov ntim tau txais kev hloov pauv graphite, nrog kev ruaj ntseg sealing, kev ua haujlwm yooj yim thiab me me qhib thiab kaw torque;
4. Ntau yam kev siv cov kav dej thiab cov ntaub ntawv sib txuas (xws li lub qhov (socket) vuam, taub qab vuam thiab cov xov txuas) tuaj yeem xaiv tau.
