Cast Iron Middle Threaded Connection Between Body And Bonnet Flanged Gate Valve

advantages

The middle screw thread gate valve is suitable for cutting off and circulating pipeline medium. It is suitable for the occasion of full opening and full closing. It can also be used for adjustment. It has the advantages of small flow resistance, unrestricted medium flow direction and small installation length of valve parts. This paper will introduce the main advantages of central screw gate valve.

1. The closing part (RAM) moves along the vertical direction of the center line of the passage for full opening and full closing and cutting.

2. The fluid resistance is small, the applicable pressure and temperature range is large, the medium flow direction is not limited, and the sealing performance is good.

3. The middle screw gate valve uses the compensation effect of slight elastic deformation produced by the elastic valve to achieve good sealing effect.

4. The valve has the advantages of light switching, reliable sealing, good elastic memory and long service life.

5. The bottom of the middle threaded gate valve adopts the same flat bottom as the water pipe, which is not easy to cause debris deposition and make the fluid unobstructed.

6. Due to the use of special sealing ring, the friction resistance during switching can be reduced, the phenomenon of water leakage can be greatly reduced, and the sealing ring can be replaced without water supply, and this sealing ring has corrosion resistance.
