Description

Technical Field

[0001] The utility model relates to the field of disassembly and inspection tools for reciprocating compressors in oil and gas fields, in particular to a device for realizing efficient disassembly and assembly of a gas valve and a valve seat of a reciprocating compressor. Background Art

[0002] Reciprocating compressors are crucial gas transmission equipment on offshore oil platforms. Their ability to operate normally and stably directly impacts numerous indicators, including gas supply and production contribution. The following issues arise during annual compressor disassembly and repair: During the disassembly and reinstallation of reciprocating compressor valves, deviations in the disassembly and reinstallation angles often lead to sticking and difficulty in removal. Particularly serious is the tendency for gravity to cause the valves to fall out of the cylinder during reinstallation of the compressor's bottom valve and seat, damaging components and slowing reinstallation. To ensure stable equipment operation, shorten the time required to disassemble and inspect the compressor valves and seats, and ensure accurate and efficient reinstallation, it is crucial to ensure accurate and efficient reinstallation of the compressor valves and seats. Utility Model Content

[0003] To address the above technical issues, the present invention provides a device for efficiently disassembling and assembling a reciprocating compressor valve and valve seat. This device can effectively improve work efficiency, not only ensuring the smooth operation of the equipment but also effectively protecting components from damage, providing effective technical support for safe production on the platform.

[0004] The utility model is realized by adopting the following technical solutions.

[0005] A device for realizing efficient disassembly and assembly of a reciprocating compressor air valve and a valve seat, comprising a support rod, a quick-release pipe clamp being sleeved on the upper portion of the support rod, a fixed block being sleeved on the lower portion of the support rod, a connecting rod mechanism being hinged between the quick-release pipe clamp and the fixed block; the connecting rod mechanism comprising a first connecting rod and a second connecting rod, both of which have sliding grooves formed thereon, bolts being simultaneously inserted into the sliding grooves of the first connecting rod and the second connecting rod; a clamping head being further connected to the end of the first connecting rod.

[0014] The technical solution of the present invention will be clearly and completely described below through specific implementation methods.

[0015] like Figure 1-2 As shown, a device for realizing efficient disassembly and assembly of a reciprocating compressor gas valve and a valve seat includes a support rod 1, a quick-release pipe clamp 2, a connecting rod mechanism 3, a bolt 4, a clamp 5, and a fixing block 8.

[0016] The support rod 1 of the present application is cylindrical, and an internal thread is formed at the bottom end of the support rod 1, so that the bottom end of the support rod 1 is threadedly connected with the bolt on the air valve 7.

[0017] The support rod 1 is fitted with a quick-release pipe clamp 2 on the upper portion and a fixing block 8 on the lower portion. The quick-release pipe clamp 2 in this application utilizes a lever-type quick-release structure, enabling rapid attachment and removal. Specifically, the quick-release pipe clamp 2 comprises an upper clamp and a lower mounting hoop, each equipped with a wrench. The mounting hoop has connecting ears on either side, through which bolts 4 are threaded. The fixing block 8 also has connecting ears on either side, through which bolts 4 are threaded. These two bolts 4 are used to connect to the connecting rod mechanism 3.

[0018] The connecting rod mechanism 3 includes a first connecting rod 31 and a second connecting rod 32, each of which has a sliding groove 33 formed thereon. The bolt 4 on the quick-release pipe clamp 2 is placed in the sliding groove 33 of the first connecting rod 31 and is ultimately passed through the connecting ear of the quick-release pipe clamp 2, thereby achieving a hinged connection between the quick-release pipe clamp 2 and the first connecting rod 31. The bolt 4 on the fixing block 8 is placed in the sliding groove 33 of the second connecting rod 32 and is ultimately passed through the connecting ear of the fixing block 8, thereby achieving a hinged connection between the fixing block 8 and the second connecting rod 32. A third bolt 4 is passed through the sliding groove 33 near one end of the first connecting rod 31 and the second connecting rod 32, and this bolt 4 hinges the first connecting rod 31 and the second connecting rod 32. The present invention achieves structural telescopic sliding by providing a first connecting rod 31 and a second connecting rod 32 with sliding grooves 33 and fixing them with bolts 4.

[0019] In the present application, a clamp 5 is further installed at the end of the first connecting rod 31. The clamp 5 is preferably Y-shaped. Finally, under the action of four pressures applied by the four ends of the two Y-shaped clamps 5, the valve seat 6 can be fixed on the air valve 7.

[0020] The method of using the utility model is as follows:

[0021] The utility model fixes the two by matching the inner hole thread at the bottom end of the support rod 1 with the outer thread on the center screw of the air valve 7, and then the quick-release pipe clamp 2 is assembled with the connecting rod mechanism 3 and the clamp head 5 and fixed on the support rod 1, and the quick-release pipe clamp 2 is adjusted downward (the distance between the quick-release pipe clamp 2 and the fixing block 8 is reduced) so that the Y-shaped clamp head 5 is clamped on the valve seat 6, and finally the air valve 7 and the valve seat 6 are fixed together. The relative positions of the two will not change during the reinstallation process. After being pushed into the cylinder body, the top screw on the valve seat body is adjusted to fix the two to the cylinder wall, so as to avoid the air valve falling out due to gravity when the bottom air valve of the compressor is reinstalled separately; loosen the quick-release pipe clamp 2, and rotate to remove the support rod 1, and the air valve 7 is reinstalled, thereby achieving the purpose of safely and efficiently reinstalling the bottom air valve of the compressor cylinder.

[0022] The quick-release pipe clamp 2, the connecting rod mechanism 3, and the clamping head 5 of the utility model are all detachable at all joints and can be quickly replaced. The utility model has a light structure and strong stability. The size of the connecting rod mechanism 3 and the Y-shaped clamping head 5 can be changed according to the needs of the equipment to obtain the optimal clamping angle and strength to adapt to valve seats of different sizes. The utility model can effectively speed up the installation speed of the gas valve at the bottom of the gas compressor; it can prevent the gas valve from being damaged by falling due to gravity and causing personal injury; it can prevent the gas valve 7 and the valve seat 6 from being skewed during the installation process, thereby damaging parts. It can save a lot of manpower, material resources, and financial resources, and provide effective technical guarantees for platform safety production.

Without departing from the design concept of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary engineering technicians in this field should fall within the scope of protection of the present invention.
