Efficient automatic compensation type gate valve and using method thereof

Abstract

The invention discloses an efficient automatic compensation type gate valve and a using method thereof, belongs to the field of gate valves, and can realize that an elastic feeler lever rubs with an extrusion cylinder to generate vibration when a valve rod is rotated to drive a gate plate body to ascend, so that a carbon dioxide aqueous solution shakes, and carbon dioxide is promoted to overflow into a telescopic hose. A rack rod is jacked to move upwards to drive a gear to rotate by 180 degrees, so that a magnetic ball rotates to be in the same polarity with a magnet piece, a piston is driven to move downwards, air in an extrusion barrel is extruded to be blown into a telescopic air bag, the telescopic air bag expands to push an extrusion plate and a movable frame to tightly abut against a heat insulation sealing gasket, and gaps are not prone to being generated between the telescopic air bag and a gate plate body; airtightness is improved; and after the heat insulation sealing gasket is abraded and has a notch in use, heat generated by friction between the heat insulation sealing gasket and the flashboard body is transmitted into the sealing frame, so that the memory telescopic rod is heated to extend, the extrusion film is extruded to promote the repair colloid to be sprayed out and repair the notch, and along with the heat, the heat insulation sealing gasket is rapidly dried, and the repair effect is enhanced.

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
