Swing check valve, also known as check valve or check valve, its role is to prevent the media back in the pipeline. The opening and closing parts are opened or closed by the medium flow and force to prevent the back flow of the medium from being called a check valve. The check valve is an automatic valve and is mainly used in the medium of one-way flow. It only allows medium to flow in one direction to prevent accidents. This type of valve should generally be installed horizontally in the pipeline.
Swing type check valve adopts built-in swing arm swing type structure. All the opening and closing parts of the valve are installed inside the valve body and do not penetrate the valve body. In addition to the sealing flange and sealing ring at the middle flange, the whole There is no leakage point, to prevent the possibility of valve leakage. Swing check valve rocker arm and the valve joint with a spherical connection structure, so that the valve flap in the 360 ​​degree range has a certain degree of freedom, there is a slight amount of appropriate position compensation.
Suitable for clean media, not for media containing solid particles and high viscosity. Swing check valve structure features 1, short structure, the structure of the length of the traditional flange check valve 1/4~1/8
2, small size, light weight, its weight is only 1/4 to 1/20 of the traditional flange check valve
3ã€Flap closes fast, water hammer pressure is small 4, horizontal or vertical pipe can be used, easy to install 5, smooth flow channel, fluid resistance is small, 6 sensitive, good sealing performance 7, short valve stroke, close the valve impact Small force 8, overall structure, simple and compact, beautiful appearance 9, long service life, high reliability.
Maintenance and care 1 The valve should be stored in a dry and ventilated room to prevent moisture, rain, and rust.
2 During the month of storage, the opening and closing parts shall be closed and the following work shall be done:
a The valve flap should be fixed in the open position b. The internal ports at both ends are blocked with foam plates. The port must be tightly sealed with a tight lid to prevent dust and rust, and keep the channel clean and flat.
c cylinder parts for proper packaging protection, shockproof and anti-collision;
d When the valve is placed, it should be stable, and the pneumatic drive device should face upward, and must not be squeezed with each other.
3 Regularly check 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.
