Description

Technical Field

[0001] The utility model relates to the technical field of valve rubber removal, in particular to a valve rubber quick removal tool. Background Art

[0002] Fracturing pump is a key equipment used in the implementation of fracturing technology in low permeability oil and gas wells. Its main function is to provide enough high-pressure liquid to expand rock cracks and inject fracturing fluid. Fracturing pump is usually composed of multiple components, including pump body, drive system, control system and hydraulic system. Valve is a rubber product with excellent wear resistance, corrosion resistance and elasticity. It is often used in sealing, protection and vibration absorption. In the oil and gas industry, valve is usually used as a seal, such as at the joint between oil well casing and drill pipe to ensure sealing performance. Because the valve body is interference-fitted with valve rubber, the fit is tight and difficult to disassemble, especially when replaced on site. It is particularly difficult, time-consuming and labor-intensive. Disassembly tools are required for disassembly. The valve rubber is usually disassembled by inserting a pressure cutter into the gap between the valve rubber and the workpiece to pry off the rubber or directly cutting the valve rubber with a pressure cutter. However, during the disassembly of the valve rubber, the valve rubber workpiece cannot be fixed. The staff cannot maintain a stable operating environment during the disassembly process, which will cause these tools to slide or lose control, causing accidental injuries. Therefore, those skilled in the art provide a kind of rapid removal tool of valve rubber to solve the problems raised in the above-mentioned background technology. Utility Model Content
