H41X (B type) silencing check valve


H41X silencing check valve with flange connection and connect two connection to clamp valve at both ends of the central shaft of the import and export oriented, flexible opening, accurate positioning, can be installed horizontally or vertically, using spring-loaded valve, can effectively reduce the water hammer pressure of the fast closing. The sealing surface adopts O ring elastic seal and metal hard seal combination sealing structure, which has good sealing performance and no noise when closing. It has the characteristics of small size, light weight, low fluid resistance, small structural length, fatigue resistance and long service life. The valve installed in the water supply and drainage, fire, heating and ventilation system can be installed at the pump outlet, to prevent backflow backwater, and damage to the pump.



The Muffler check valve is based on its structure

1 valve, silent check valve cylindrical disk-shaped, around the seat of the shaft for rotation channel, because the valve channel into a streamlined, flow resistance than the small rise butterfly valve, suitable for large caliber occasions in low flow and no flow frequently changes, but not for the pulsating flow, the sealing can't lift. Butterfly check valve is divided into single, double flap and most of the three types, the three forms are mainly divided into the valve diameter, the purpose is to prevent the media stop flow or reverse flow, weakening the hydraulic impact.

2. Check valve: check valve sliding along the vertical centerline of valve body, the check valve can only be installed on the horizontal pipeline, the valve on the high pressure small caliber check valve

The ball can be used in the valve. The valve shape of the Muffler check valve is the same as that of the globe valve, so it has a large coefficient of fluid resistance. Its structure and cutting

The check valve is similar, the valve body and the valve clack are the same as the globe valve. A guide sleeve is made of the upper part of the valve and the lower part of the valve cover, and the valve guide guide can be freely lifted in the valve guide guide

When the medium is flowing downstream, the valve is opened by the medium thrust. When the medium stops, the valve falls on the valve seat and stops the flow of the medium. Straight through type

The direction of the inlet and outlet passage of butterfly check valve is perpendicular to the direction of the valve seat; the vertical lift check valve, the direction of its inlet and outlet of the medium and the valve passage Fang Xiangxiang

The flow resistance is smaller than that of straight through.

3. Silent check valve: check valve that rotates around the pin pin in the valve seat. The disc type check valve is simple in structure and can only be installed on the horizontal pipeline, and the sealing is better.

4. Silent check valve: valve sliding along the centerline of valve body. The pipe type check valve is a new kind of valve, which is small in size and light in weight

Good art, is one of the development direction of check valve. But the fluid resistance coefficient is slightly larger than that of the swing check valve.

5, compression type check valve: This valve is used as boiler feed water and steam cut-off valve, it has lift check valve and stop valve or angle valve comprehensive function.

In addition, there are - some do not apply to pump outlet check valve is installed, such as valve, spring type, Y type check valve.
