Description

Technical Field

[0001] This utility model relates to the field of air guiding device technology, and in particular to an air guiding device for a compressor valve plate. Background Technology

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it by driving the piston through the motor, and then discharges high-temperature, high-pressure refrigerant gas through the discharge pipe, providing power for the refrigeration cycle. Most of the gas guiding devices in the compressor need to use valve plates to control the flow of gas.

[0003] An existing patent (publication number: CN221779605U) discloses a compressor valve plate air guiding device, including an air guiding device, a pressure reducing device, and a connecting device. The connecting device includes a connecting pipe, an air guiding end, and a diverting end. The air guiding end and the diverting end are respectively disposed on both sides of the connecting pipe. The pressure reducing device is disposed on the air guiding end. The air guiding device includes an air guiding pipe and a connector. The connector is respectively disposed at both ends of the air guiding pipe and is fixedly connected by threads. One end of the air guiding pipe is fixedly connected to one end of the pressure reducing device through the connector. Through the multi-channel diverting end, when it is necessary to adjust the air intake of the compressor, the air intake can be more easily controlled by controlling the opening and closing of the shut-off valve on the diverting end, thereby improving the compression efficiency. The pressure reducing device not only filters and purifies the air source, but also adjusts and stabilizes the pressure.

[0004] However, the device described above regulates the intake air volume by controlling the shut-off valve on the splitter end. Although the intake air volume can be controlled and regulated, multiple shut-off valves need to be controlled during the adjustment process, which causes inconvenience during use. Furthermore, due to the multiple splitter ends, when installing the device, multiple splitter ends need to be connected to the intake connection pipe in sequence, which leads to inconvenience during installation or disassembly.

[0005] Therefore, this utility model proposes a compressor valve plate air guiding device. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a compressor valve plate air guiding device.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a compressor valve plate air guiding device, including a pressure reducing mechanism and a connecting pipe, wherein the connecting pipe is fixedly connected to the input end of the pressure reducing mechanism, and further includes:

[0008] The regulating air guide assembly consists of an exhaust sleeve located below the pressure reducing mechanism, an regulating sleeve, and a fan-shaped air intake box. The top of the regulating sleeve is connected to the bottom of the exhaust sleeve, and the fan-shaped air intake box is located on one side of the regulating sleeve. A snap-fit ​​rotating shaft is rotatably connected to the center of the regulating sleeve. A fan-shaped adjusting block is provided on the snap-fit ​​rotating shaft inside the regulating sleeve. An annular through hole is opened on the side of the regulating sleeve near the fan-shaped air intake box, and the fan-shaped air intake box is connected to the regulating sleeve through the annular through hole.

[0009] Furthermore, multiple annular through holes are provided, and the multiple annular through holes are distributed in a ring, with the included angle between two adjacent annular through holes being equal.

[0010] The beneficial effects of adopting the above-mentioned further solution are: multiple annular through holes are evenly distributed in an annular shape with adjacent included angles being equal. This distribution results in a more balanced flow distribution when fluid passes through, improving product performance and helping to enhance structural stability and reduce stress concentration.

[0011] Furthermore, the arc circumference of the side of the fan-shaped air intake box near the adjusting sleeve is greater than the sum of the arc circumferences of the multiple annular through holes, and the arc circumference of the fan-shaped adjusting block is adapted to the sum of the arc circumferences of the multiple annular through holes.

[0012] The beneficial effects of adopting the above-mentioned further solutions are: the large arc design on one side of the fan-shaped air intake box can gather more airflow and ensure sufficient air intake; the fan-shaped adjustment block and the arc circumference of the annular through hole are matched, which can accurately control the air intake, optimize the air intake efficiency, ensure stable gas supply during equipment operation, and improve overall work efficiency.

[0013] Furthermore, the regulating sleeve is provided with limit strip blocks on both sides below the exhaust sleeve, and the curvature of the fan-shaped regulating block is adapted to the inner wall diameter of the regulating sleeve.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the limiting strip blocks on both sides below the adjusting sleeve can effectively prevent the fan-shaped adjusting block from losing control of displacement, ensuring the accuracy of adjustment; the fan-shaped adjusting block is adapted to the inner wall of the adjusting sleeve and fits tightly, ensuring good sealing during adjustment, ensuring that the airflow flows along the expected path, and improving the stability of equipment operation.

[0015] Furthermore, an air intake pipe is fixedly connected to one side of the fan-shaped air intake box, and a flange is provided on the side of the air intake pipe away from the fan-shaped air intake box, with a rubber sealing ring embedded in the flange.

[0016] The beneficial effects of adopting the above-mentioned further solution are: the fan-shaped air intake box connects to the air intake pipe, which facilitates quick docking with other equipment; the flange is embedded with a rubber sealing ring, which greatly enhances the sealing performance of the connection, effectively prevents gas leakage, ensures stable operation of the air intake system, and reduces energy loss and efficiency reduction caused by air leakage.

[0017] Furthermore, a drive motor is provided on one side of the adjusting sleeve, and the output end of the drive motor passes through the adjusting sleeve and is connected to the snap-fit ​​rotating shaft.

[0018] The beneficial effects of adopting the above-mentioned further solution are: the adjustment sleeve is equipped with a drive motor, the output end of which is directly connected to the rotating shaft. The drive motor can precisely control the rotation speed and direction of the rotating shaft, so that the associated components can operate efficiently and stably, making it easier to flexibly control the operating status of the equipment and improve the overall work efficiency and operation convenience.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, by adjusting the setting of the air guiding component, the adjusting sleeve and the exhaust sleeve are connected to ensure smooth airflow. The fan-shaped air inlet box is located on one side and is connected to the adjusting sleeve through an annular through hole to facilitate gas introduction. The snap-fit ​​rotating shaft drives the fan-shaped adjusting block to rotate, which can accurately control the air intake volume to meet the needs of different working conditions. This adjustable design improves the flexibility and adaptability of the equipment, ensures stable gas delivery, improves overall operating efficiency, and reduces energy consumption and failure risk.
