Description

Technical Field

[0001] The utility model relates to the technical field of compressor valve disassembly, in particular to a reciprocating compressor valve puller disassembly device. Background Technique

[0002] The piston compressor is an important device for boosting and transporting associated gas in oil fields. At present, most of the piston compressors in use are two-stage compressions, and each stage is equipped with an intake valve and an exhaust valve, which are respectively used to control intake and exhaust. Due to the particularity of the compressed and transported medium, in order to ensure the safe and stable operation of the unit, the regular maintenance and overhaul of the valves are particularly important;

[0003] During the compressor overhaul process, when disassembling the valve, usually maintenance personnel need to use fixed special tools to disassemble the valve. Currently, the commonly used disassembly methods are to use a copper rod to strike and vibrate or shake the special tool left and right to loosen the adhesion between the valve and the valve seat, and then forcibly pull out the valve. This method causes great damage to the valve and reduces the service life of the valve;

[0004] Due to the particularity of the valve installation structure and the phenomenon of oil and carbon accumulation often existing in the cylinder cavity, using the existing disassembly tools and methods to disassemble the valve installed in the valve cavity is not only time-consuming and laborious, but also easy to damage the valve body.

[0005] Therefore, a reciprocating compressor valve puller disassembly device is proposed to meet the disassembly requirements of the valve. Content of the Utility Model

[0006] The purpose of the utility model is to solve the defects existing in the prior art, and a reciprocating compressor valve puller disassembly device is proposed.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A reciprocating compressor valve puller disassembly device includes a lead screw, a support frame, and a connecting lead screw. A limit nut is welded at the center position of the support frame. A gasket is fixed on the upper side of the limit nut. The connecting lead screw passes through the limit nut and the gasket. A connecting lead screw nut is arranged on the upper side of the gasket, and the connecting lead screw nut is threadedly installed with the connecting lead screw;

[0009] A clamping nut is arranged below the limit nut, and the connecting lead screw is installed with the clamping nut.

[0010] Further, the clamping nut is welded by 3 nuts.

[0011] Further, the diameter of the connecting lead screw is smaller than the threaded hole diameter of the limit nut;

[0012] The diameter of the connecting lead screw is the same as the diameter of the threaded hole of the connecting lead screw nut and the threaded hole of the clamping nut.

[0013] Furthermore, the support frame is columnar. The support frame is fixedly connected to the limit nut and the lead screw nut by welding. The limit nut is welded to the exact center of the support frame, and the lead screw nuts are symmetrically welded to both sides of the support frame. The distance between the lead screw nuts is equal to the outer diameter of the cylinder.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] The structure of the present utility model is simple, easy to manufacture, and low in cost. It can be quickly assembled, is small in size, convenient to carry, fast and convenient to arrange, has high working efficiency, saves both time and labor costs, can meet the requirements of maintenance personnel for safely and quickly disassembling air valves, and has a wide application prospect in the maintenance process of piston compressors, especially suitable for first-line workplaces.
