Structural principle of flapper valve
Structural Principle
A baffle valve usually consists of a valve body, clamp, baffle, valve stem, sealing ring, handle, etc. In the closed state of the valve, a sealing line is formed between the baffle and the bottom of the valve, and a closed space is formed between the valve and the pipeline. When the medium flows through the valve, the baffle begins to function. The position of the baffle can be achieved by rotating the valve stem. The larger the rotation angle, the larger the channel through which the medium passes, and the greater the flow rate.
Working Principle
The working principle of a baffle valve is based on Gongli's law, which means that when a liquid passes through a pipeline, the volume flow rate of the liquid remains constant within the same cross-sectional area. Therefore, the flow rate of the liquid can be controlled by controlling the cross-sectional area of the pipeline. The baffle of the baffle valve can be rotated to adjust the cross-sectional area of the pipeline, thereby controlling the flow of liquid.
In addition to flow control, the baffle valve can also achieve liquid level control and pressure regulation through the adjustment of the valve stem. By adjusting the position of the baffle, the flow rate and velocity of the liquid in the pipeline can be changed, thereby changing the level of the liquid. Adjusting the position of the valve stem can change the cross-sectional area of the pipeline, thereby changing the flow rate and pressure of the liquid.
