How much is the energy-saving two-piece knife gate valve

Two piece knife gate valveNamed after the valve body using a two-piece combination.

1. The main body of the two-piece knife type gate valve adopts a two piece symmetrical casting structure, and its valve body is thicker and stronger than the old integrated knife type gate valve. The inside and outside of the valve body are all CNC high-precision machined, making its overall accuracy higher, sealing better in all aspects, and the valve more resistant to medium erosion. The appearance is smoother, smoother, and more beautiful.

2. The valve body is designed with a full bore, and the bore inner cavity is designed with a reasonable slope flow flushing port structure, which can effectively improve the smoothness of the medium passing through the valve chamber flow channel and effectively solve the problems of poor sealing leakage caused by poor sealing of the medium slot of the old integrated knife type gate valve.

3. The bidirectional sealing structure can achieve bidirectional pressure without jamming or leakage, and is not affected by erosion, greatly improving the service life of the valve and exceeding the standardization of pressure bearing capacity.

Performance characteristics:

1. The valve seat adopts a U-shaped structure integrated hot melt molded rubber sealing ring, which has a higher sealing ring density, better resilience, and is more wear-resistant, water-resistant, oil resistant, and erosion resistant.

2. The rubber valve seat is embedded in the valve chamber flow channel and is wrapped in multiple directions by two valve bodies, ensuring that more than 95% of its area is not washed away by the medium, truly extending the service life and sealing performance of the valve.

3. The rubber sealing contact surface of the U-shaped valve seat is designed as a convex V-shaped structure, which reduces the contact area with the medium or gate plate, effectively improving the service life of the valve seat and solving problems such as high torque, tight thrust, and difficult opening and closing.

4. The sealing design of the valve seat rubber middle channel is a concave U-shaped structure, which makes its contact area with the gate smaller, has better resilience, lighter torque, and stronger sealing. It can also be equipped with a needle core injection port, which can repeatedly ensure the sealing performance of the rubber after wear and tear. 5. There is a curved scraper structure designed between the valve seat and the valve body, and the use of PTFE sealing can effectively scrape off the adhesive medium on the gate, improving the overall service life of the valve seat.
