Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration compressors, in particular to a piston refrigeration compressor with an energy regulating valve. Background Art

[0002] The piston refrigeration compressor is the heart of the refrigeration system. It sucks in low-temperature, low-pressure refrigerant gas from the intake port, compresses it through the piston driven by the motor, and then discharges high-temperature, high-pressure refrigerant gas to the exhaust port, providing power for the refrigeration cycle, thereby realizing the refrigeration cycle of compression → condensation → expansion → evaporation (heat absorption).

[0003] With the development of economy and society, the application of refrigeration equipment has become more and more extensive, and energy conservation and emission reduction have gradually become issues that need to be paid attention to in all areas of production and life. The heat load of the refrigeration compressor is changing during operation. When the cooling capacity of the compressor is greater than the heat load, it must be unloaded, otherwise it must be loaded. When the heat load is equivalent to the cooling capacity in summer, it must be unloaded in winter. When cooling a fixed heat source, the temperature is high at the beginning and it must be fully loaded. When the temperature drops, it must be unloaded. Conventional refrigeration compressors cannot adjust the heat load when working. As the use time increases, it will cause adverse consequences such as reduced refrigeration efficiency, increased energy consumption, and reduced equipment life. Utility Model Content

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] Piston refrigeration compressor with energy regulating valve, including

[0007] main body;

[0008] An end cap, mounted at one end of the main body;

[0009] Its characteristics are as follows: a connecting seat is installed on the end cover, a mounting hole is provided on the connecting seat, a regulating valve is installed in the mounting hole, and the regulating valve is disassembled and connected to the connecting seat through a fixing part, thereby realizing precise adjustment of the cooling capacity, improving the stability and energy efficiency of the system, and at the same time enhancing the adaptability and flexibility of the compressor, and increasing the service life of the equipment. At the same time, the disassembly and connection make the regulating valve easy to repair and replace.

[0010] Furthermore, a positioning portion is provided on the regulating valve and a positioning groove is provided on the connecting seat. The positioning portion moves along the positioning groove, so that the regulating valve can maintain a stable trajectory during movement, avoiding adjustment errors caused by shaking or offset. This design improves the installation accuracy of the regulating valve.

[0011] Furthermore, a guide surface is provided at the positioning groove, and the guide surface is arranged at an angle. The existence of the guide surface enables the positioning part to smoothly enter and leave the positioning groove, thereby realizing precise adjustment and stable positioning of the regulating valve. After being constrained by the two grooves, the positioning part is more difficult to deviate or shake, thereby ensuring the stable operation of the compressor.

[0012] Furthermore, a limiting groove communicating with the positioning groove is provided in the connecting seat, and the positioning part moves along the limiting groove. During the movement, the positioning part is not only guided by the positioning groove but also constrained by the limiting groove, thereby achieving more accurate and stable positioning.

[0013] Furthermore, an inflatable seal is provided in the limiting groove, which can effectively prevent the refrigerant or other working medium from leaking out from the gap between the connecting seat and the positioning portion.

[0014] Furthermore, a connecting hole is provided on the connecting seat, and a matching hole is provided on the positioning portion. The fixing piece passes through the connecting hole and the matching hole, thereby ensuring a stable connection between the regulating valve and the connecting seat and improving the operating efficiency and reliability of the compressor.

[0015] Furthermore, a limiting portion is provided on the inner side of the mounting hole, and a corresponding matching portion is provided on the regulating valve. The limiting portion cooperates with the matching portion to limit the installation position of the regulating valve, which not only improves the connection stability and accuracy, but also simplifies the installation and maintenance process, providing a strong guarantee for the stable operation of the compressor.

[0016] Furthermore, the limiting portion is arranged in a conical shape. Since the conical limiting portion and the matching portion can form close contact and fit, it helps to improve the sealing performance of the connection, reduce the leakage of refrigerant or other working media, and simplify the installation and maintenance process of the regulating valve.

[0017] Furthermore, a sealing ring is installed on the limiting part. When the regulating valve is installed in the mounting hole, the sealing ring is provided to improve the sealing effect of the connection between the limiting part and the regulating valve to prevent medium leakage.

[0018] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0035] A positioning groove 14 is provided on the connecting seat 12, and the positioning groove 14 is communicated with the mounting hole 18. One end of the positioning groove 14 is open, and a positioning portion 17 is provided on the adjusting groove, and the positioning portion 17 matches the positioning groove 14. A limiting groove 15 communicating with the positioning groove 14 is provided in the connecting seat 12, and the limiting groove 15 is communicated with the bottom of the positioning groove 14, and the limiting groove 15 matches the positioning portion 17. When installing the regulating valve 13, the positioning portion 17 is moved down along the positioning groove 14 to the specified position, and the regulating valve 13 is rotated so that the positioning portion 17 disengages from the positioning groove 14 and enters the limiting groove 15, and moves to the specified position.

[0036] A connecting hole 23 is provided on the connecting seat 12, and the connecting hole 23 is communicated with the limiting groove 15. A matching hole 24 is provided on the positioning portion 17.

The fixing piece can be connected with screws.

[0037] In order to facilitate the cooperation between the positioning part 17 and the positioning groove 14, a guide surface 22 is provided at the open end of the positioning groove 14.

When rotating, the matching portion 21 rotates along the limiting portion 20. The matching between the limiting portion 20 and the matching portion 21 not only improves the connection stability and accuracy, but also simplifies the installation and maintenance process, providing a strong guarantee for the stable operation of the compressor. A sealing ring 19 is also provided at the limiting portion 20. The sealing ring 19 is provided to improve the sealing effect of the connection between the limiting portion 20 and the regulating valve to prevent medium leakage.
