Description

Multi-angle adjustable dismounting tool for heavy-duty air valve of reciprocating compressor Technical field: The invention relates to the technical field of compressor air valve maintenance, in particular to a multi-angle adjustable dismounting tool for a heavy-duty air valve of a reciprocating compressor. The background technology is as follows: Reciprocating compressors are widely used in petrochemical enterprises, and the reasons for faults are numerous due to the complex structure. In long-term production practice, the most common fault parts of the reciprocating compressor are found to be a gas valve, a piston ring, a stuffing box, friction pairs of some connectors and the like, but more than 60% of faults of the reciprocating compressor occur on the gas valve, and the fault of the gas valve can be found in time to be quite important for diagnosing the fault of the reciprocating compressor. Reciprocating compressor gas valves play an important role in compressor performance. The correct maintenance of the gas valve not only can improve the efficiency and the service life of the compressor, but also can reduce the energy consumption and the failure rate. The service life of the air inlet valve and the air outlet valve of the reciprocating compressor is about one year, the service life of the air valve of the reciprocating compressor with severe operation conditions is even less than half a year, and the air valve maintenance is one of the conventional maintenance items of the reciprocating compressor. The installation of the first-stage cylinder air valve of the reforming booster K-1202/ABC of the continuous reforming device of the Harbin petrochemical company is always puzzled by maintenance work due to the factors of large weight, special installation angle and the like. The company has 27 reciprocating machines, wherein the reforming booster K-1202/ABC is huge in machine body, the quality of the first-stage cylinder air valve is large, and the installation angle is the same. The operator is required to semi-lie on the ground and lift the air valve by hand, and the weight of the air valve and the valve cover reaches 30 kg. If the valve cannot be installed in place at one time in the installation process, the valve can fall off to cause personnel injury risk. In the maintenance operation of the air valve of the reciprocating compressor, the air valve is damaged or corroded, and the disassembly is difficult. The labor intensity of staff is high and the working efficiency is low. The air valve is easy to damage due to improper maintenance and installation, and the maintenance and material cost is increased. The air valve has low repairing rate and poor economic benefit. The air valve is too heavy to carry by manpower, and is difficult to disassemble and assemble. An air valve weighing several tens of jin is sent into the valve cavity of the air chamber, the labor intensity is high by adopting manual pushing and lifting. In the process of installation or disassembly, the air valve is heavy and easy to collide or drop to cause the damage of the air valve. The reciprocating compressor cannot efficiently realize the fine safety maintenance.
