How to select a gate valve for circulating water systems

Circulating water systems are widely used in many fields such as industrial production and building HVAC. Among them.gate valveAs a core component in controlling the flow of water, its selection is critical to the operation of the system.

In conventional industrial circulating water systems, wedge type single gate gate valves are favored because of their simple structure, mature manufacturing technology and low cost. This kind of gate valve has good sealing, can effectively avoid circulating water leakage. At the same time, the contact area between its gate and valve seat is moderate, and the water flow resistance is small when opening and closing, which helps reduce energy consumption. However, it has certain requirements for the cleanliness of the medium, which may affect the sealing effect if there are more impurities in the water.

For large circulating water systems with high sealing requirements, resilient gate valves are more suitable. The resilient gate can automatically adjust the degree of contact with the valve seat under different working conditions, and can maintain good sealing performance even when the temperature and pressure changes are large. In addition, it can adapt to complex water quality conditions, with strong resistance to impurities.

In small building circulating water systems, theConcealed rod gate valveIt is a good choice. It is compact, takes up little space, is easy to operate, and is affordable enough to meet the basic needs of a small system.

In summary, in the selection of circulating water system gate valve, need to consider the system size, water quality, pressure, temperature and other factors to ensure that the gate valve can be stable and efficient operation.
