The role of the inlet muffler check valve is to prevent reverse flow, allowing only the medium to flow in one direction. Normally, this type of valve operates automatically. The valve flap is opened by the fluid pressure flowing in one direction. When the fluid flows in the opposite direction, the fluid pressure and the self-closing flap of the valve flap act on the valve seat to cut off the flow. It should not be used for media containing solid particles and high viscosity.

The imported muffler check valve belongs to the automatic valve class. Its function is to prevent the back flow of the medium in the pipeline. It is mainly used for the medium flowing in one direction, and only allows the medium to flow in one direction to prevent accidents.

Take the representative of the United States Weidun check valve brand VTON, for example, Xiaobian here to introduce the import of muffler check valve maintenance and maintenance methods!

The maintenance and maintenance of imported silencing check valves are as follows:

1) The opening and closing parts during storage and transportation should be in the closing device, and the following work should be done at the same time:

1 The flap of the silencing check valve should be fixed in the open position.

2 The internal ports at both ends are blocked with foam plates. The port must be tightly sealed with a stuffy cap to prevent dust and rust, and keep the channels clean and flat.

3 cylinder parts for proper packaging protection, shockproof and anti-collision;

2) The silencer check valve should be placed in a stable manner with the pneumatic drive device facing upwards and must not be squeezed with each other.

3) Periodic inspection should be performed when placed for a long time. Every three months, check the dirt and rust on the two channels and the sealing surface, and the welding conditions. After wiping off the dirt and rust, re-apply the anti-rust oil to protect it.

4) In order to prevent the medium from flowing backwards, check valves should be installed on equipment, devices and pipelines;

5) Muffler check valve is generally suitable for cleaning medium, not suitable for media containing solid particles and high viscosity;

6) The vertical silencing check valve should be used on the horizontal pipes passing through 50mm nominally;

7) The silencer check valve should be stored in a dry and ventilated room to prevent moisture, rain, and rust.
