The shut-off valve, also known as the shut-off valve, is a forced-sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface to not leak. When the medium enters the valve from below the disc, the resistance that the operating force needs to overcome is the frictional force between the valve stem and the packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the valve stem The diameter of the valve should be large, otherwise the valve stem will bend failure. According to the connection mode, it is divided into three types: flange connection, threaded connection, and welding connection. After the appearance of the self-sealing valve, the medium flow direction of the shut-off valve changes from above the valve disc into the valve cavity. At this time, under the action of the medium pressure, the force of closing the valve is small, while the force of opening the valve is large, and the diameter of the valve stem can be corresponding To reduce.
