Product Description

Overview of Z45X/Z41X-10/16Q Soft Seal Gate Valve; The opening and closing parts of the soft seal gate valve adopt the gate, and the movement direction of the gate is perpendicular to the direction of the fluid, so the soft seal gate valve can only be fully opened and closed, and cannot be used for adjustment and throttling. The gate has two sealing surfaces, and the two sealing surfaces of the most commonly used mode gate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 50, and 2*52 ""when the medium temperature is not high. Huaguang soft sealing gate valve achieves good sealing effect by using the deformation compensation function generated by the integral encapsulation of the gate, and overcomes the phenomena of poor sealing, water leakage and rust of general gate valves. Features of Z45X/Z41X-10/16Q Soft Seal Gate Valve: 1. Low flow resistance. The medium channel inside the valve body is straight, the medium flows in a straight line, and the flow resistance is small. 2, it is labor-saving when opening and closing. Compared with the cut-off valve, because whether it is open or closed, the moving direction of the gate is perpendicular to the flowing direction of the medium. 3. High height and long opening and closing time. The opening and closing stroke of the gate is large, and the lowering is carried out by the screw. 4, water hammer phenomenon is not easy to produce. The reason is the long closing time. 5. The medium can flow in any direction on both sides, which is easy to install. Both sides of the gate valve channel are symmetrical. 6. The structural length (the distance between two connecting end faces of the shell) is small. 7. Simple shape, short structural length, good manufacturing technology and wide application range. Principle of Z45X/Z41X-10/16Q Soft Seal Gate Valve: Soft-seal gate valves are divided into two types: open-stem soft-seal gate valves and hidden-stem soft-seal gate valves. Usually, there are trapezoidal threads on the lifting rod. Through the nut in the middle of the gate and the guide groove on the valve body, the rotary motion is changed into linear motion, that is, the operating torque is changed into operating thrust. When the valve is opened, when the lifting height of the gate is equal to 1:1 times of the valve diameter, the fluid channel is completely unblocked, but this position cannot be monitored during operation. In actual use, the vertex of the valve stem is taken as the symbol, that is, the position that can't be opened is taken as its full open position. In order to consider the locking phenomenon caused by temperature change, it is usually the position of fully opening the valve after opening to the top position and then reversing for 1/2-1 turn. Therefore, the fully open position of the valve is determined according to the position (i.e. stroke) of the gate. Generally, this kind of valve should be installed horizontally in the pipeline.
