Today I would like to introduce to you some brief introduction to the Check Valve and its working principle.
The butterfly plate of the Check Valve is installed in the diameter direction of the pipe. In the cylindrical channel of the Check Valve disc, the disc-shaped butterfly plate rotates around the valve axis with a rotation angle between 0° and 90°. When rotated 90°, the valve is in a fully open state. This kind of
Universal Valve is generally installed horizontally in the pipe.
As a component used to realize on-off and flow control of pipeline systems, Check Valve have been widely used in many fields such as petroleum, chemical industry, metallurgy, and hydropower. In the already recognized Check Valve technology, its sealing form mostly adopts sealing structure, and the sealing materials are rubber, polytetrafluoroethylene, etc. Due to the limitations of structural characteristics, it is not suitable for industries such as high temperature resistance, high pressure resistance, corrosion resistance, and wear resistance. Multi-layer soft stacked sealing rings are fixed on the valve plate. Compared with traditional Check Valve, this Check Valve has high temperature resistance, is easy to operate, has no friction in opening and closing, and follows the torque of the transmission mechanism when closing.
Working principle of Check Valve: The ventilation Check Valve is driven by an electric motor to drive the actuator, so that the disc can rotate freely within 90° to achieve the purpose of opening and closing or adjusting the medium flow.
Purpose of Check Valve: The Check Valve uses a polytetrafluoroethylene-lined butterfly plate with a spherical sealing surface. This Universal Valve is easy to operate, has tight sealing performance, and has a long service life; it can be used to quickly cut off or adjust flow. Use. Suitable for applications requiring reliable sealing and good regulation characteristics.
