1. Poor sealing:
Since the sealing of the wedge gate valve is achieved by the friction between the gate and the valve seat, if the gate and the valve seat are not well matched or the gate surface is not smooth, leakage problems will occur.
2. Large operating force:
Since there is a large sealing force between the gate and the valve seat of the wedge gate valve, a large operating force is required to open or close the valve, which is inconvenient to operate.
3. Blockage problem:
Since the gate thickness of the wedge gate valve is large, it is easy to cause blockage when the fluid passes through, affecting the smooth flow of the fluid.
4. Friction and wear:
Since there is friction between the gate and the valve seat of the wedge gate valve, long-term use will cause wear on the gate surface and affect the sealing performance.
5. Corrosion problem:
If the material of the wedge gate valve is not properly selected or the use environment is highly corrosive, it will cause corrosion of the valve and make it fail.
6. Unstable operation:
Since the gate of the wedge gate valve is easily impacted by the medium during operation, it will cause unstable operation and affect the service life of the valve.
The above problems may affect the normal use of wedge gate valves. Users should pay attention to solving these problems when selecting and using wedge gate valves.
