Ductile resilient seated gate valve (Shanghai Valve Co., Ltd. Tianjin Shield)

Resilient seated gate valve RVHX-16Q Profile: dark bar resilient seated gate valve opening and closing member is, the direction of movement of the fluid direction perpendicular to the gate, the gate valve can only be fully open and fully closed, can not be adjusted and the throttle . Ram has two sealing surfaces, sealing surfaces the most common mode of gate valve forming wedge, wedge angle with the valve parameters vary, usually 50, the medium temperature is not high when 2 ° 52. Wedge gate valve can be made into a whole, called the rigid gate; also be made to produce small quantities of deformation gate in order to improve its process of, to make up the sealing surface angle deviations arising during processing, such gate board called the flexible gate, usually the flange connection. Resilient seated gate valve is also called the lift rod valve (also called clear shot valve). Often movements are trapezoidal threaded rod, through the guide slot valve and the 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 diameter of 1: 1 times, the fluid channel is completely smooth, but at run time, this position can not be monitored. Actual use, is the apex of stem as a sign that the fixed position, as its fully open position. Temperature appears to consider locking phenomenon, usually open to the vertex position, and then rewind 1 / 2-1 circle, as the location of a fully open valve. Therefore, the fully open position of the valve, according to damper position (ie, travel "to determine.
