The flat gate valve is a common valve type, and its working principle is to control the on-off of the fluid by the rising and falling of the gate. Specifically, when the valve is required to be opened, the valve rod drives the gate to move upward to open the fluid passage, so as to realize the flow of fluid. When the valve is required to be closed, the valve stem moves downward, and the gate plate descends accordingly, sealing the fluid passage and preventing the fluid from passing through.
The flat gate valve is mainly composed of valve body, valve seat, gate plate, valve rod and transmission device. The valve body is the main part of the valve, usually made of cast iron, carbon steel and other materials, with sufficient strength and rigidity to withstand the pressure of the fluid. The valve seat is the key component of the valve seal and is usually made of good materials to ensure the sealing performance. The gate is a key component for controlling the on-off of fluid. It is usually made of cast iron, carbon steel and other materials. It is rectangular in shape and moves up and down to realize on-off of fluid. The valve stem is a component that connects the actuator to the gate and is usually made of corrosion resistant materials such as stainless steel.

The working principle of the flat gate valve mainly depends on the connection and movement of the valve rod and the gate. When the valve is closed, the gate is in close contact with the valve seat under the action of the spring to form a seal. When the valve is opened, the transmission device drives the gate to move upward through the valve rod, forming a certain gap with the valve seat, so as to realize the flow of fluid.
In addition, the plate gate valve usually has the function of two-way sealing, that is, no matter which direction the fluid passes through the valve, it can achieve effective sealing. This is mainly due to the special design of the valve seat and the double-sided sealing structure of the gate. Such bidirectional sealing features make the flat gate valve have wide applicability in many occasions.
In general, the working principle of the flat gate valve is to realize the on-off and control of the fluid through the lifting and falling of the gate. This valve has the advantages of simple structure, convenient manufacturing and good sealing performance, so it is widely used in the industrial field.
