Gate valve, also known as gate valve or gate valve, is a widely used valve. It is through the lift of the gate to control the valve opening and closing, the gate is perpendicular to the direction of the fluid, changing the relative position between the gate and the seat can change the size of the channel.

Gate valves have the following advantages:

1, the fluid resistance is small, the sealing surface is brush and erosion of the medium is small.

2, less effort to open and close.

3, the medium flow is not limited, does not disturb the flow, does not reduce the pressure.

4, simple shape, short structure length, good manufacturing process, wide range of application.

1. Use:

Install water and steam pipes for opening and closing devices.

Ii. Brief description of structure:

1. Both ends of the branch pipe are welded, and the opening and closing of the valve are controlled by the gear transmission device.

2. The valve is closed mainly through the bevel gear mechanism on the valve cover and can be adjusted for the double single gate, universal top, clamp ring, etc., through the valve body internal guidance for lifting movement.

3. The sealing surface of the seat is made of cobalt-based cemented carbide surfacing, with good wear resistance and abrasion resistance.

4. The surface of the valve stem is treated with corrosion resistance and abrasion resistance.

5. Pressure self-tightening sealing mechanism, by the medium pressure pressure wedge seal ring to achieve sealing, the higher the medium pressure sealing performance is better.

1. When the valve is installed, it should be vertically installed on the horizontal pipe, and the medium can enter from any side. Install the valve only after the pipe is flushed. 2. When the valve is in use, it should be fully opened or fully closed, and cannot be used as a regulating valve.
