The valve flap of the brass shut-off valve is removed from the closed position,Its valve seat and the valve sealing surface are no longer contact,Therefore, its sealing surface mechanical wear is very small.,Therefore, its sealing performance is very good.,A disadvantage is that the particles in the sealing plane may be sandwiched in the flow medium.。but,If the valve is made into steel ball or porcelain ball,This problem is also tough。Since most cutoff valve seats and flaps are relatively easy to repair or replace,And there is no need to remove the entire valve from the pipeline when repairing or replacing the sealing element.,This is applicable in the case where the valve and pipeline welding are。
Since the medium is changed in the direction of flow through such valves,Therefore, the minimum flow resistance of the shutoff valve is also higher than that of most other types of valves.。However,According to the valve body structure and the valve stem relative to、Outlet channel layout,This situation can be improved。at the same time.Due to the small trip between the shutoff valve,The sealing surface can withstand multiple times,So it is very suitable for occasions that require frequent switches.。
Shutdown valve can be used in most medium flow systems。Petrochemical、electricity、metallurgy、Urban construction、Various forms of cut-off valves for chemical and other departments。
Purpose of the use of the shutoff valve,But due to the large opening and closing moment、Long structure length,Usually the nominal path is limited250mmthe following,Also400mmof,But pay attention to the import and export direction when choosing。generally150mmThe following cut-off valve media flows from below the valve.,and200mmThe above cutoff valve is mostly from above the valve.。This is considering the closure moment of the valve。In order to reduce the opening or closing moment,generally200mmThe above cutoff valve is provided in the inner or outer passage valve。
The brass cutoff valve is obviously the advantage is:
(1)During the opening and closing process,Due to the frictional force of the valve flap and the valve body sealing surface,Thus wear.
(2)The opening height is generally only for the valve seat channel diameter1/ 4,Therefore, the thyristor is much smaller.。
(3)Typically only one sealing surface on the valve body and the valve flap,It is better to manufacture,Easy to repair。but,The disadvantage of the shutoff valve is not overlooked.。The disadvantage is mainly larger than the flow resistance coefficient,Therefore, pressure loss,Especially in the hydraulic device,This pressure loss is obvious。
