    Soft sealing gate valve, valve industry, soft sealing gate valve is a gate opening and closing parts, RAM direction of motionperpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. There are two gate sealing surface, the most common mode of gate valvesealing surface to form two wedge, wedge angle varies with the valve parameters, usually 50, medium is not high temperature is 2 ° 52''''.

     The principle 

    Wedge gate valve can be made into a whole, called the steel gate;also be made to produce small deformation of the gate, in order to improve its process, make up the sealing surface angle deviationsarising during processing, this gate is called the flexible gate.

     Soft sealing gate valve into the next shot soft sealing gate valveand the dark bar soft sealing gate valve two. Usually in the lift rod with trapezoidal thread, through the guide groove of the middle of the nut and the valve body, the rotary motion into linear motion,which is the operating torque thrust into operation. Open the valve,when the gate valve lift height is equal to 1:1 times the diameter,the fluid flow channel completely, but at run time, this position is unable to monitor. 

     Actual use, is the apex of the stem as a symbol,which means that the fixed position, as its full open position.Temperature changes appear to consider locking phenomenon,usually open to the vertex position, and then rewind 1/2 1 circle, as a fully open valve position. Therefore, the fully open position of the valve, based on the location of gate (i.e. travel 'to determine. This type valve should normally be installed horizontally in the pipeline.
