Description
Technical Field
The utility model relates to a gate valve technical field specifically is a can prevent effectively that the mistake from bumping gate valve of hand wheel.
Background
A flat gate valve is a sliding valve whose closing member is a parallel gate plate. The closing member can be a single gate or a double gate with a spreader mechanism in between. The pressing force of the shutter against the valve seat is controlled by the pressure of the medium acting on the floating shutter or the floating valve seat. The flat gate valve can be divided into a manual flat gate valve, a pneumatic flat gate valve and an electric flat gate valve according to a driving mode, and can be divided into a flat gate valve with a diversion hole, a flat gate valve without a diversion hole, an oil field flat gate valve, a pipeline flat gate valve, a gas flat gate valve and the like according to purposes and use occasions. The opening and closing part of the gate valve is a gate plate, the moving direction of the gate plate is vertical to the fluid direction, and the gate valve can only be fully opened and fully closed and cannot be adjusted and throttled. The gate has two sealing surfaces, the most common mode gate valve has two sealing surfaces forming a wedge shape, the wedge angle varies with the valve parameters, usually 5 °, and the medium temperature is not high and is 2 ° 52'. The gate plate of the wedge gate valve can be made into a whole, namely a rigid gate plate, or can be made into a gate plate capable of generating micro deformation so as to improve the manufacturability of the gate plate and compensate the deviation of the angle of a sealing surface in the machining process, and the gate plate is called an elastic gate plate. When the gate valve is closed, the sealing surface can be sealed only by medium pressure, namely, the sealing surface of the gate plate is pressed to the valve seat on the other side by the medium pressure to ensure the sealing of the sealing surface, namely, the gate valve is self-sealed. Most gate valves are forcedly sealed, namely, when the valves are closed, the gate plates are forced to press the valve seats by external force so as to ensure the sealing performance of the sealing surfaces. The gate plate of the gate valve moves linearly along with the valve rod, and is called a lifting rod gate valve and a rising rod gate valve. Usually, the lifting rod is provided with trapezoidal threads, and the rotating motion is changed into the linear motion, namely the operation torque is changed into the operation thrust force through a nut at the top end of the valve and a guide groove on the valve body. When the valve is opened, the passage of fluid is completely open when the gate plate is lifted to a height equal to 1:1 times the gate diameter, but this position is not monitored during operation. In actual use, the vertex of the valve rod is used as a mark, namely, the opening and closing position is used as the full opening position. To account for the occurrence of lock-up due to temperature changes, the valve was opened to the top position and then reversed 1/2-1 cycles to assume the fully open valve position. Therefore, the fully open position of the valve is determined by the position, i.e., stroke, of the shutter plate. In some gate valves, a stem nut is arranged on the gate plate, and the hand wheel rotates to drive the valve rod to rotate, so that the gate plate is lifted.
However, when the existing manual flat gate valve is used, the valve is loosened due to the fact that the hand wheel is touched by mistake, and serious results are generated.
