[0001] The utility model belongs to the technical field of disassembly and assembly tools, and particularly relates to a reciprocating compressor exhaust valve disassembly and assembly tool. Background Technique

[0002] The reciprocating compressor exhaust valve disassembly and assembly tool is an auxiliary tool designed specifically to facilitate the disassembly and assembly operations of the exhaust valve by operators. Its main features include a structure connecting the guiding screw rod and the base to provide stable support; an operating handwheel to achieve the assembly and disassembly of the air valve; designs such as fixed slots and handles for convenient operation. In a restricted space, the designs of the rotating cavity, rotating rod, and rotating shaft enable operators to apply force easily, improving the disassembly and assembly efficiency. The overall design has a reasonable structure and is easy to operate, helping to improve work efficiency and reduce labor intensity. This tool plays an auxiliary support and fixation role in the exhaust valve disassembly and assembly operations, making the operation more convenient and efficient.

[0003] However, when disassembling the air valve conventionally, since the exhaust valve is directly below the cylinder, when disassembling and assembling, people have to directly lift the air valve. Generally, the space below the compressor cylinder is relatively small and it is not easy to apply force, so a disassembly and assembly tool that is convenient for applying force is needed to complete the disassembly and assembly operations. Content of the Utility Model

[0004] The purpose of the utility model is to provide a reciprocating compressor exhaust valve disassembly and assembly tool to solve the problem that when disassembling the existing conventional air valve, since the exhaust valve is directly below the cylinder, when disassembling and assembling, people have to directly lift the air valve, and generally, the space below the compressor cylinder is relatively small and it is not easy to apply force as mentioned in the above background technique.

[0014] Compared with the prior art, the present utility model provides a reciprocating compressor exhaust valve disassembly and assembly tool, which has the following beneficial effects:

[0015] In the reciprocating compressor exhaust valve disassembly and assembly tool, the following advantages can be achieved through the settings of the rotating cavity, the rotating shaft and the rotating rod:

[0016] Convenience: Operators are no longer restricted by space and unable to effectively hold the grip. Through the design of the rotating rod, it is more convenient to apply force, making it easier to perform disassembly and assembly operations.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0028] The present utility model provides a reciprocating compressor exhaust valve disassembly and assembly tool as Figures 1-4 shown, including a grip 1 and a fixed rod 2 disposed at the middle position on the upper side of the grip 1;

[0029] An air valve pipe 3 is connected to the upper end position of the fixed rod 2, a guide screw rod 5 is connected to the outer side of the fixed rod 2, a handwheel 4 is disposed at the outer position of the lower end of the guide screw rod 5, and a base 6 is disposed at the outer position of the lower side of the air valve pipe 3;

[0030] Rotating cavities 12 are respectively formed at the left and right positions of the grip 1, a rotating rod 11 is disposed inside the rotating cavity 12, and a rotating shaft 10 is disposed at the connection position between the rotating rod 11 and the grip 1;

[0031] Handles 7 are respectively disposed at the left and right positions of the base 6, fixed grooves 9 are formed inside the left and right sides of the base 6, and a fixed nut 8 is disposed at the middle position on the upper side of the base 6.

[0032] In this embodiment, when disassembling the air valve conventionally, since the exhaust valve is directly below the cylinder, when disassembling and assembling, the operator has to directly lift the air valve. Generally, the space below the compressor cylinder is relatively small and it is not easy to apply force.

[0033] When the operator uses this exhaust valve disassembly and assembly tool, first insert the fixed rod 2 through the middle holes of the guide screw rod 5 and the base 6, screw the air valve pipe 3 of the fixed rod 2 onto the air valve, and thread-connect the other side of the fixed rod 2 with the grip 1.

[0034] Subsequently, align the fixing grooves 9 on both sides of the base 6 with the valve gland bolts and fix them directly below the valve chamber. Rotate the handwheel 4 of the guiding lead screw 5 clockwise to install the air valve in place, and rotate the handwheel 4 of the guiding lead screw 5 counterclockwise to disassemble the air valve, thus quickly completing the disassembly and assembly operations.

[0035] As Figures 1-4 shown, the fixing rod 2 passes through the guiding lead screw 5 and the base 6. The fixing rod 2 is connected to the grip 1 by means of threaded connection. The rotating shaft 10 is connected to the rotating rod 11 by means of integral connection. The rotating rod 11 can rotate in the rotating cavity 12 through the rotating shaft 10. The handwheel 4 is connected to the guiding lead screw 5 by means of integral connection. The base 6 is connected to the guiding lead screw 5 by means of threaded connection. The fixing groove 9 is specifically a strip-shaped threaded groove. The lifting handle 7 is connected to the base 6 by means of bolt connection. The fixing rod 2 can rotate within the guiding lead screw 5 and the base 6. The base 6 can rotate on the guiding lead screw 5 by means of threads.

[0036] Preferably, the operator can disassemble and assemble the exhaust valve by lifting the exhaust valve. When the distance for the operator to lift the exhaust valve is limited, resulting in a small distance between the grip 1 part of the fixing rod 2 and the ground and making it difficult to hold the grip 1, when rotating the fixing rod 2 to disassemble and assemble the exhaust valve, the rotating rod 11 can be rotated out of the rotating cavity 12 by means of the rotating shaft 10. By holding the rotating rod 11 and rotating the grip 1 of the fixing rod 2 forcefully, a more convenient force-applying disassembly and assembly operation can be carried out on the air valve.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
