Introduction to H41H Lift Forged Steel Check Valve
H41H lifting forged steel check valve is one of the important links in the production process control system. It is a valve that controls the one-way flow of the medium in the pipeline and prevents the medium from flowing back.
Features of H41H lifting forged steel check valve
1. H41H lifting forged steel check valve has the advantages of simple structure, reliable action, and convenient maintenance, and is widely used in purification equipment, petroleum, chemical, metallurgical, power, textile and other production processes
2. When the medium flows into the valve body as indicated by the arrow on the valve body, the pressure of the medium acts on the valve disc to generate an upward thrust. When the thrust of the medium is greater than the gravity of the valve disc, the valve opens. When the force exerted by the pressure of the medium behind the valve on the valve disc plus the gravity of the valve disc itself is greater than the force exerted by the pressure in front of the valve on the valve disc, the valve closes and prevents the medium from flowing back
