German standard hard seal gate valve

Product overview

The opening and closing part of the hard seal gate valve is the gate plate, the movement direction of the gate plate is perpendicular to the direction of the fluid, the gate valve can only be fully opened and closed, can not be adjusted and throttled. The gate has two sealing faces, the two sealing faces of the common mode gate valve form a wedge, wedge Angle varies with valve parameters, usually 50, 2°52 'when the medium temperature is not high. Wedge gate valve disc can be made into a whole, called rigid disc; Can also be made into a trace deformation of the gate, in order to improve its technology, make up for the Angle of the sealing surface in the process of the deviation, this kind of gate is called elastic gate.

Characteristics of copper core copper rod protection gate

1, is a commonly used cut-off valve, mainly used to put through or cut off the pipeline medium: gate valve applicable pressure, temperature and diameter range is very large, especially suitable for medium and large diameter pipeline.

2, wedge type steel single gate structure is simple, small size, the use of VB, it is suitable for room temperature, medium temperature of all kinds of media and pressure environment.

3, fluid resistance is small. The medium channel inside the gate valve body is straight through, the medium does not change its flow direction when flowing through the gate valve, so the flow resistance is small.

4, open and close less effort. When opening and closing, the direction of gate movement is perpendicular to the direction of medium flow. Compared with the straight globe valve, the gate valve takes less effort to start.

5, the flow direction of the medium is generally not restricted. The medium can flow from both sides of the gate valve in any direction, can achieve the purpose of switching on or cutting off. Easy to install, suitable for medium flow direction may change in the pipeline.

Copper core copper rod protective gate valve advantages:

1, compact structure, good valve steel, smooth channel, small flow resistance coefficient.

2, sealing surface is made of brass, long service life.

3, the use of flexible graphite packing, tight sealing, light and flexible operation.

4, driving mode split dynamic, electric, pneumatic, gear transmission, structure form: elastic wedge type single gate, steel wedge type single gate and double gate type.

5, widely used in water supply and drainage, metallurgy, petroleum, chemical, pharmaceutical, electric power, textile and urban construction and other industries, in the nominal pressure ≤ 1.0mpa, water, oil media for opening and closing on the pipeline.
