The bypass hydraulic control pressure relief valve is installed on the bypass pipe on the outlet side of the check valve in the main pipe, and is used together with the check valve to realize the driving and automatic control by using the pressurized liquid in the pipe, completely solving the traditional two-stage closing. When the valve eliminates the water hammer pressure, the discharge causes the pump rotor component to reverse. Because it has the function of adjustable closing time, it is suitable for various complicated pipelines to eliminate water hammer pressure. It is a new type of pressure relief valve with popularized application value.
New bypass hydraulic control relief valve is introduced to the market
It is reported that three types of pressure relief valves with a diameter of 80mm, 150mm and 300mm have been designed and manufactured at a nominal pressure of 1.6MPa. They are used in tap water, metallurgical cooling circulating water and petrochemical cooling circulating water piping systems. After nearly one year of operation, the valve The action is flexible and the closing time is adjustable. For the complex pipe network system, the water hammer effect is eliminated, and the problem of long return time and backwater back inversion of the two-stage shut-off valve is completely solved. Explain that the valve structure and performance design method is feasible and the parameters are selected accurately.
