Structural principle of differential pressure balancing valve

Structural Principle:

The valve is composed of a valve body, valve cover, valve core spring, control conduit, and pressure regulator. The valve is installed on the return pipe of the heating pipeline, and the working chamber on the valve is connected to the water supply pipe through the control pipe. Eliminate the flow deviation caused by external network pressure fluctuations. When the water supply pressure increases, the water supply pressure difference increases, and the pressure sensing film drives the valve core to move downwards and close the valve opening, thereby maintaining a constant value. When the water supply pressure decreases, the pressure sensing film drives the valve core to move upwards. No matter how the pressure changes in the pipeline, the pressure difference valve can maintain a constant pressure difference and flow rate applied to the controlled object.

 

Working Principle:

The working principle is to adjust the aperture size inside the valve to maintain the pressure difference when the fluid passes through the valve within the set range. Differential pressure balancing valves typically consist of a valve body, valve core, and regulator. There is a hole on the valve core, and the size of the hole will also be adjusted when the regulator rotates. The interior of the valve body is usually divided into inlet, outlet, and orifice. During valve operation, fluid enters from the inlet port, passes through the throttle hole, passes through the hole in the valve core, enters the outlet port, and finally enters the next pipeline system.
