I. overview of H41H lifting check valve
Lifting check valve is selected in the nominal pressure pn1.6-6.4mpa, operating temperature -29 ~ 550℃ of petroleum, chemical, thermal power station and other conditions of the pipeline. Applicable medium: water, oil, steam, etc.
Ii. Structural features of H41H lift-type check valve:
1, lifting type check valve has the advantages of simple structure, reliable action, convenient maintenance, etc., widely used in purification equipment, petroleum, chemical, metallurgy, electric power, textile and other production processes
2. When the medium flows into the valve body from the direction indicated by the arrow of the valve body, the pressure of the medium ACTS on the valve disc to generate upward thrust. When the pressure of the medium is greater than the gravity of the valve disc, the valve opens. When the pressure of the media behind the valve ACTS on the disc plus the force of the disc's own gravity is greater than the force of the pressure in front of the valve ACTS on the disc, the valve closes to prevent media backflow.
It can design and manufacture check valves of different structure and connection forms according to the requirements of customers.
Scope of use: the product can be used for water, steam. Oil as a medium on the pipeline, do one-way opening and closing.
