Special features and application scope of groove type elastic seat sealing gate valve

Scope of use of groove type elastic seat sealing gate valve

Groove type elastic seat sealing gate valveIt is produced by introducing high-tech rubber and valve manufacturing technology from Europe, overcoming defects such as rubber aging and rusting. The groove gate valve achieves good sealing effect by compensating for the slight elastic deformation generated by the elastic gate plate. This valve has significant advantages such as lightweight opening and closing, reliable sealing, good elastic memory, and long service life. The product is widely used in tap water, sewage, and seawater; The pipeline lines in industries such as water treatment, environmental protection, construction, fire protection, petroleum, chemical, power, food, medicine, textile, shipbuilding, and energy serve as regulating and intercepting devices.

Special features of groove type elastic seat sealing gate valve

1. Groove type elastic seat sealed gate valve flat bottom seat: Generally, after flushing the pipe with water, foreign objects such as cement blocks, iron filings, etc. accumulate in the groove at the bottom of the valve, which can easily cause leakage due to the inability to close tightly. The bottom of the groove elastic seat sealed gate valve adopts the same flat bottom design as the pipeline, which is not easy to cause debris accumulation and allows fluid to flow smoothly.
2Groove type elastic seat sealed gate valve precision cast valve bodyThe valve body of the groove gate valve is precision cast, and the precise geometric dimensions ensure the sealing of the valve without the need for any internal processing.

3. Rubber coating for groove type elastic seat sealed gate valve plate: The valve plate of groove gate valve is coated with high-quality rubber both inside and outside as a whole. The first-class rubber vulcanization technology in Europe ensures accurate geometric dimensions of the vulcanized valve plate, and the rubber is firmly attached to the ductile iron valve plate, which is not easy to fall off and has good elastic memory.

4Three O-ring sealsDue to the use of three "O" ring sealing designs for the valve stem and cover of the groove gate valve, friction resistance during opening and closing can be reduced, water leakage can be greatly reduced, and the sealing rings can be replaced without stopping the flow of medium in the pipeline.
Beneficial for drinking: Due to the non-toxic epoxy resin coating inside the groove gate valve, the inner and outer surfaces of the valve plate are completely covered with rubber without the occurrence of molten iron or corrosion, making it suitable for drinking.
5.Groove type elastic seat sealing gate valve labor-saving deviceFor large-diameter groove gate valves, an additional labor-saving device can be installed, which requires about half of the normal torque. Only a small handwheel is needed to fully open or close the valve under pressure. The labor-saving device needs to fully open the valve before restoring its labor-saving function for each action.
