The Advantages of Common Gate Valve Structure
The advantages of common gate valve structure
1, the valve opening and closing needs more effort. Is compared with the cut-off valve, because whether it is opened or closed, the direction and the movement of the gate and the media flow direction is perpendicular.
2, the height is big, open and close time is long. Gate opening and closing stroke is larger, the decline is carried out through the screw.
3, water hammer phenomenon is not easy to produce. The reason is the closing time is long.
4, the media can flow in any direction on both sides, easy to install. Gate valves are symmetrical on both sides of the channel.
5, the length of the structure is smaller.
6, sealing surface is easy to wear and tear, affect the service life. When the sanitary valve is opened and closed, the two sealing surfaces of the gate plate and the valve seat are mutually friction and sliding, so as to produce the abrasion under the pressure of the medium, and the sealing performance and the service life can be shortened.
7, the price is more expensive. Contact sealing surface is more complex processing, especially the gate seat sealing surface and more parts are not easy to process.
8, the body is simple, the structure of short length, good manufacturing process, wide application.
9, compact structure, good rigidity, smooth channel, small flow resistance, sealing surface of stainless steel and carbide, long service life, the use of PTFE packing.
