A high-efficiency automatic compensation gate valve and its use method

Abstract

The invention discloses a high-efficiency automatic compensating gate valve and a method for using the same, belonging to the field of gate valves, which can realize vibration generated by friction between an elastic contact rod and an extrusion cylinder when the valve rod is driven to rise by rotating the valve rod, so that the carbon dioxide aqueous solution shakes , prompting the carbon dioxide to overflow into the telescopic hose, and the upward movement of the rack bar drives the gear to rotate 180°, so that the magnetic ball rotates and the magnet piece is in the same state, and drives the piston to move downward, squeezing the air in the cylinder Blow into the telescopic air bag to make it expand and push the extruded plate and the movable frame tightly against the heat insulation gasket, so that it is not easy to form a gap with the gate body, thereby enhancing the sealing performance, and the heat insulation gasket will not be damaged during use. After wear and tear, the heat generated by friction with the gate body is transferred to the sealing frame, which makes the memory telescopic rod heated and extended, and the extruded film promotes the ejection of the repair gel, repairs the gap, and is accompanied by heat to make it dry quickly , to enhance the repair effect.

Description

technical field [0001] The invention relates to the field of gate valves, in particular to a high-efficiency automatic compensation gate valve and its application method. Background technique [0002] The gate valve is an opening and closing part gate. The direction of movement of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. It is mainly used to control air, water, steam, various corrosion The flow of various types of fluids such as aggressive media, mud, oil, liquid metal, and radioactive media. With the continuous development of industrial production, the scope of use of gate valves is becoming wider and wider. [0003] During the working process of the gate valve, the movement of the gate realizes the flow of fluid, but there is a gap between the movement of the gate and the inside of the gate valve, which makes it easy for the fluid to flow to the gap, which not onl...

[0003] During the working process of the gate valve, the movement of the gate realizes the flow of fluid, but there is a gap between the movement of the gate and the inside of the gate valve, which makes it easy for the fluid to flow to the gap, which not only reduces the sealing performance of the gate valve, but also affects the gate valve. Subsequent use of the
