Hydraulic gate valve is a commonly used control valve. It is based on the principle of hydraulic pressure, through the hydraulic drive to control the flow and pressure of fluid.It is mainly composed of valve body, valve seat, gate, sealing device, hydraulic actuator and so on.
The working principle of the hydraulic gate valve is to control the opening degree of the gate through hydraulic pressure, thereby controlling the flow of fluid. When hydraulic pressure is transmitted to the hydraulic actuator, it drives the gate plate to move upward or downward, thereby changing the opening degree of the valve. When the gate is completely closed, the valve is in a closed state; when the gate is fully open, the valve is in a fully open state; when the gate is in the middle position, the valve is in an adjustment state, and the opening degree of the gate can be controlled by changing the hydraulic pressure. , thereby regulating the flow of fluid.
Hydraulic gate valve is suitable for various liquid media, such as water, oil, gas, etc., and can withstand high working pressure and temperature. It is widely used in petroleum, chemical industry, metallurgy, electric power, water treatment and other fields. Hydraulic gate valve has the characteristics of simple structure, high reliability and easy maintenance, and can adapt to the flow adjustment and cut-off control needs under various working conditions.
In general, the hydraulic gate valve also has the feature of remote control. By connecting with the control system, remote control and automated control can be achieved, improving production efficiency and safety. At the same time, hydraulic gate valves can also be equipped with various accessories, such as manual devices, electric devices, pneumatic devices, etc., to meet the requirements of different application scenarios. In general, the hydraulic gate valve is a control valve with comprehensive functions, high reliability and wide adaptability. It plays an important role in various industrial fields and can meet the flow control and cut-off control needs of different media.
