Application of gate valve in water supply system
Gate valve is one of the products frequently used in the water supply industry. It can only be fully opened and fully closed, and cannot be adjusted and throttled. It is used to cut off the water flow in the water supply pipeline. Generally, gate valves are selected when the water supply pipeline network has little effect on the covering depth. Here I have to mention the butterfly valve, a valve product that has a similar effect to the gate valve.
Like the gate valve, the butterfly valve can switch and adjust the flow, and the price of the butterfly valve will be lower than that of the gate valve under the same specification. Butterfly valves are also used when the diameter of the pipe is large in order to reduce the depth of the pipe covering in the water supply pipe. However, through the feedback of customer use data in the past ten years, the number of failures of butterfly valves is higher than that of gate valves. Therefore, gate valves are obviously a more cost-effective choice for water supply pipeline applications.
Gate valves have been well used in the water supply industry. Soft-sealed gate valves have more advantages than traditional gate valves, as follows:
- The valve body and bonnet of the soft-sealed gate valve are cast by precision casting method, one-time forming, strong and durable.
- There is no pit at the bottom of the soft-sealed gate valve, and no residue remains, which can greatly reduce the failure rate of gate valve opening and closing.
- The size of the valve plate of the soft-sealed gate valve is uniform, with strong interchangeability and easy maintenance.
It should also be noted that when opening and closing the soft-sealed gate valve, it is enough to achieve the water-stop effect. Do not close it too tightly, otherwise it will not be easy to open or cause the rubber lining of the rubber-lined gate valve to peel off.
