New bypass hydraulic control pressure relief valve developed to the market
It is reported that the design and manufacture of three diameter 80mm, 150mm, 300mm pressure relief valve, nominal pressure 1.6MPa, used in tap water, metallurgical cooling circulating water, petrochemical cooling circulating water pipe system, after nearly 1 year of operation proved that the valve Flexible action and adjustable closing time. As to complex pipe network system, the water hammer elimination effect is good, and the problems of long time of slow closing of the two-stage shut-off valve and reversal of backwater impact are solved completely. Description of valve structure and performance of the design method is feasible, accurate parameter selection. Bypass hydraulic control relief valve installed in the main pipeline check valve outlet side of the bypass pipe, with the check valve used in conjunction with the use of pressurized liquid in the pipeline to achieve the drive and automatic control, completely solve the traditional two-stage shutdown Valve to eliminate water hammer pressure when the pump rotor rotor parts to reverse the problem. Due to its adjustable closing time, it is applicable to a variety of complex pipelines to eliminate water hammer pressure. It is a new type of pressure relief valve with extended application value.
