H41Y、H41HThe lifting type steel check valve with flange connection is one of the important links in the production process control system. It is a valve to control the unidirectional flow direction of medium in the pipeline to prevent the medium backflow, achieve the purpose of automatic control and protect the normal operation of the equipment.

1. When the medium flows into the valve body from the arrow of the valve body, the pressure of the medium acts on the valve disc to generate upward thrust. When the medium thrust is greater than the gravity of the valve disc, the valve opens. When the force exerted on the disc by the pressure behind the valve plus the gravity of the disc itself is greater than the force exerted by the pressure in front of the valve, the valve is closed to prevent the backflow of medium
2. H41h, h41y lifting type steel check valve has the advantages of simple structure, reliable action and convenient maintenance. It is widely used in purification equipment, petroleum, chemical, metallurgy, electric power, light and textile production process

Check valve installation should pay attention to the following matters
1. In the pipeline, do not make the check valve bear the weight, large check valve should be independently supported, so that it is not affected by the pressure produced by the pipeline system.
2. During installation, the direction of medium flow should be consistent with the arrow direction of valve body.
3. Lift type vertical disc check valve shall be installed in vertical pipeline.
4. Lift type horizontal disc check valve shall be installed on horizontal pipeline.
