1/2 Inch Throttle Element Pressure Check Relief Valve High Precision QTYH-15

Description

Pressure relief valve is a valve that can automatically maintain stable outlet pressure by adjusting the inlet pressure to a required outlet pressure and relying on the energy of the medium itself.

Application

The pressure reducing valve is a valve that adjusts the inlet pressure to a certain required outlet pressure and relies on the energy of the medium itself to automatically maintain the outlet pressure. From the point of view of fluid mechanics, the pressure reducing valve is a throttling element whose local resistance can be changed, that is, by changing the throttling area, the flow velocity and the kinetic energy of the fluid are changed, resulting in different pressure losses, thereby achieving the purpose of decompression. Then, relying on the adjustment of the control and regulation system, the fluctuation of the post-valve pressure is balanced with the spring force, so that the post-valve pressure remains constant within a certain error range.

Ordering Code

Principle

The pressure reducing valve adopts the opening degree of the opening and closing member in the control valve body to adjust the flow rate of the medium, reduce the pressure of the medium, and adjust the opening degree of the opening and closing member by the action of the pressure behind the valve, so that the pressure behind the valve is maintained within a certain range. Inside, the cooling water is sprayed into the valve body or behind the valve to lower the temperature of the medium. This type of valve is called a vacuum desuperheating valve.
Pressure relief valve quick and easy automatic selection is included. The valve is characterized by keeping the outlet pressure and temperature within a certain range in the case of constant changes in inlet pressure.
