Groove type elastic seat sealing gate valve: excellent sealing performance and convenient maintenance advantages

The groove type elastic seat sealing gate valve is a commonly used industrial valve, widely used in the medium transportation of water supply and drainage, fire protection, petroleum, chemical, metallurgy and other fields. It has the characteristics of simple structure, flexible operation, and good sealing performance, and is considered an ideal substitute for globe valves.

Structural characteristics

The groove type elastic seat seal gate valve is mainly composed of valve body, valve cover, valve stem, sealing ring, packing, and other parts. Its unique design lies in the fact that the bottom of the valve is equipped with an elastic seat ring, which can automatically compensate for small displacements caused by temperature changes or changes in pipeline pressure, ensuring that the sealing performance of the valve is always in good condition. In addition, during the opening and closing process of the valve, the buffering effect of the elastic seat ring can reduce the impact of water hammer on the valve and improve its service life.

operational principle

When the water flows through the groove type elastic seat sealing gate valve, the valve opens and the water flows downstream through the gap between the valve core and the valve seat. During the process of valve closure, the elastic seat ring is subjected to water pressure, causing slight deformation, thereby compensating for the small displacement of the valve caused by temperature changes or changes in pipeline pressure. In this way, it can ensure that the valve is always in a good sealing state and avoid leakage.

Applicable scope

The groove type elastic seat sealing gate valve is suitable for various working conditions in the fields of water supply and drainage, fire protection, petroleum, chemical industry, metallurgy, etc. Especially in situations that require strict sealing, low noise, and no leakage, such as water purification, power plant condensate recovery, etc., it is more ideal.

Installation and Maintenance

The installation of groove type elastic seat sealed gate valves should ensure a stable and horizontal foundation. Before installation, the pipeline should be cleaned to ensure that there are no foreign objects blocking it. During installation, attention should be paid to avoiding damage to valves or accessories. During use, the sealing performance of the valve should be regularly checked, and worn sealing rings and packing should be replaced in a timely manner. For valves that operate for a long time, regular maintenance should be carried out, including cleaning, lubrication, and checking the tightness of fasteners.
