Regus Regus imported thread gate valve
The opening and closing member of the threaded gate valve is a plug-shaped valve flap having a flat or tapered surface, and the valve flap moves linearly along the center line of the fluid. The movement form of the valve stem has a lifting rod type (the valve stem is lifted and lowered, the hand wheel does not move up and down), and there is also a lifting rotary rod type (the hand wheel and the valve stem rotate together and the nut is set on the valve body). The tube stop valve is only suitable for full opening and full closing, and adjustment and throttling are not allowed.

Regus Regus imported wire buckle gate valve definition:
Thread gate valve, internal thread gate valve, high pressure gate valve, and tube stop valve are forced-sealed valves, so when the valve is closed, pressure must be applied to the valve flap to force the sealing surface to not leak. When the medium enters the valve body from below the valve flap, the resistance to be overcome by the operating force is the friction force of the valve stem and the packing and the thrust generated by the pressure of the medium. The force of closing the valve is greater than the force of opening the valve, so the valve The dia
meter of the rod is large, otherwise the valve stem may be bent. In recent years, after the appearance of the self-sealing valve, the medium flow direction of the shut-off valve is changed into the valve chamber from above the valve flap. At this time, under the action of the medium pressure, the force of closing the valve is small, and the force of opening the valve is large, the valve stem is The dia
meter can be reduced accordingly. At the same time, this type of valve is also tight under the action of the medium. China's valve "three-way to give" has stipulated that the flow of the stop valve, all from top to bottom.
When the internal thread gate valve is opened, the opening height of the valve flap is 25% to 30% of the nominal dia
meter, the flow rate has reached the maximum, indicating that the valve has reached the fully open position. Therefore, the full open position of the shutoff valve should be determined by the stroke of the valve flap.
