Exercise: The gate valve with the valve stem linear motion, also called clear shot valve. Often movements are trapezoidal threaded rod through the gate valve guides and valve on top of the nut, and the rotary motion into linear motion, which is the operating torque thrust into action. Open the valve, when the gate valve lift height equal to the diameter of the 1: 1 times PZ41H slagging valve manufacturers, fluid channel is completely smooth, but at run time, this position is not monitored. Advantages: 1, small flow resistance. Body internal media channel is straight, medium into a linear flow, small flow resistance. 2, more effort when opening and closing. Is compared with the shut-off valve in terms Weifang valve, because either open or closed, the shutter movement direction are perpendicular to the flow direction of the medium. 3, height, long opening and closing times. Gate opening and closing stroke of a larger drop is carried out by a screw. 4, easy to produce water hammer phenomenon. The reason is that long off time.
