Valve lock valve or gate valve, a valve is the most widely used. It is through the lifting of the gate to control the opening and closing of the valve, the gate perpendicular to the direction of the fluid, changing the relative position between the gate and the valve seat can change the size of the channel.

Gate valve has the following advantages:

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

2, open and close more effort.

3, medium flow unrestricted, no flow, no pressure reduction.

4, the body is simple, the structure of short length, good manufacturing process, wide application.

First, use:

Installation of water, steam pipeline, for the opening and closing device.

Two, structure brief:

The 1 ends of the branch pipe are connected by welding, and the opening and closing of the valve is controlled by a gear transmission device.

2 the main valve closed by the valve cover and the cone gear mechanism can be adjusted for double single gate, universal top, clamping ring and other components, through the valve body guide for lifting movement.

3 seat sealing surface is made of cobalt base hard alloy welding, wear resistance, good scratch resistance.

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

5 pressure self tight sealing mechanism, through the medium pressure wedge seal ring to achieve the seal, the higher the pressure the better the sealing performance of the media.

Three, installation instructions: 1 valve installation must be installed vertically on the horizontal pipe, the media can enter from any side. Valve can be installed only after the pipeline is flushed. 2 the valve in use, should be fully open or fully closed, can not be adjusted using the valve.
