Exercise method
When the gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the gate is pressed against the valve seat on the other side only by the medium pressure to ensure the sealing of the sealing surface, which is self-sealing. Most gate valves are forcibly sealed, that is, when the valve is closed, the gate is forced to be pressed against the valve seat by external force to ensure the tightness of the sealing surface.

 

Movement mode: The gate of the gate valve moves linearly with the valve stem, which is also called open-rod gate valve. Usually, there is trapezoidal thread on the lifting rod, and the rotary motion is changed into linear motion through the nut on the top of the valve and the guide groove on the valve body, that is, the operating torque is changed to the operating thrust. When the valve is opened, when the lift height of the gate is equal to 1: 1 of the valve diameter, the fluid channel is completely clear, but this position cannot be monitored during operation. In actual use, the apex of the valve stem is used as a mark, that is, the position that cannot be opened, as its fully open position. In order to consider the lock-up phenomenon caused by temperature change, it is usually opened to the top position, and then back to 1 / 2-1 turn, as the position of the fully open valve. Therefore, the fully open position of the valve is determined according to the position of the gate (i.e., stroke). Some gate valve stem nuts are set on the gate, and the rotation of the hand wheel drives the valve stem to rotate, and the gate is raised. Rotary stem gate valve or called dark stem gate valve.

 

 

Gate valve advantages

 

1 . Small flow resistance. The medium channel inside the valve body is straight through, the medium flows in a straight line, and the flow resistance is small.

 

2 . Less effort when opening and closing. Compared with the shut-off valve, whether it is open or closed, the direction of movement of the shutter is perpendicular to the direction of medium flow.

 

3 . high height, long opening and closing time. The opening and closing stroke of the gate is large, and the lowering is performed by the screw.

 

4 . water hammer phenomenon is not easy to produce. The reason is the long shutdown time.

 

5 . The medium can flow in any direction on both sides, which is easy to install. Gate valve channels are symmetrical on both sides.

 

6 . The structure length (distance between the two connecting end faces of the shell) is small.

 

7 . Simple shape, short structure length, good manufacturing process and wide application range.

 

8 . compact structure, good valve rigidity, smooth channel, small flow resistance, sealing surface using stainless steel and hard alloy, long life, using PTFE packing. Reliable sealing. Light and flexible operation.
