Description

Technical Field

[0001] The utility model relates to the technical field of reciprocating compressors, in particular to a reciprocating compressor air valve disassembly and assembly tool. Background Art

[0002] A reciprocating compressor is a compressor that changes the cylinder volume periodically through the reciprocating motion of the piston or diaphragm in the cylinder, and realizes the pressurization and delivery of the gas. It is a positive displacement compressor, which can be divided into piston type and diaphragm type compressors according to the components that perform reciprocating motion. The working principle of a reciprocating compressor is that the crankshaft drives the connecting rod, and the connecting rod drives the piston to move up and down. When the piston moves downward, the cylinder volume increases, the intake valve opens, the exhaust valve closes, and air is sucked in; when the piston moves upward, the cylinder volume decreases, the outlet valve opens, and the intake valve closes, completing the compression process.

[0003] During the operation and maintenance of reciprocating compressor units, an important task is to inspect and repair the gas valve. At present, most of the gas valves are disassembled and assembled manually during the gas valve inspection and maintenance process. The gas valve disassembly and assembly process involves opening the cylinder head of the compressor cylinder. If the pressure relief replacement is unqualified, it may cause the flammable, explosive and toxic media in the cylinder to leak or volatilize, which will cause serious consequences and pose a safety hazard. At the same time, manual disassembly and assembly of gas valves usually takes a long time, causing the production line to shut down for a long time for maintenance work, thereby affecting production efficiency. In view of the above problems, a reciprocating compressor gas valve disassembly and assembly tool is proposed to solve them. Utility Model Content

[0021] The lifting assembly 3 includes a rotating rod 301, which is rotatably connected to the inside of the support base 2. The left and right surfaces of the rotating rod 301 are fixedly connected to active bevel gears 302. The right side of the support base 2 is fixedly installed with a first motor 307.

[0022] Preferably, the lifting assembly 3 also includes two fixed blocks 306, which are respectively fixedly connected to the side surfaces of the left and right support plates 4. The bottoms of the two fixed blocks 306 are rotatably connected to the lifting screw rods 303.
