Abstract
Description
Technical Field
[0001] This invention relates to the field of compressors, specifically to a compressor valve assembly. Background Technology
[0002] A compressor is a driven fluid machine that elevates low-pressure gas to high-pressure gas; it is the heart of a refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it using a piston driven by a motor, and then discharges high-temperature, high-pressure refrigerant gas through the discharge pipe, providing power for the refrigeration cycle and thus realizing the refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption). Compressors are classified into reciprocating compressors, screw compressors, centrifugal compressors, linear compressors, etc. This entry introduces the working principle, classification, components, specifications, operating requirements, production, common faults, environmental protection requirements, selection principles, installation conditions, and development trends of compressors. Compressors can be classified according to their operating principle into positive displacement compressors and dynamic compressors. Positive displacement compressors are further divided into reciprocating compressors and rotary compressors; dynamic compressors are further divided into axial flow compressors, centrifugal compressors, and mixed flow compressors.
[0003] Currently, the intake valve opening of compressors is an open structure. Since compressors need to be placed outdoors to work, most of them are only equipped with a protective net for simple isolation. When stationary, they cannot automatically close, which makes it easy for debris to enter and cause damage to the interior. Therefore, the market urgently needs to develop a compressor valve assembly to help people solve the existing problems. Summary of the Invention
[0004] The purpose of this invention is to provide a compressor valve assembly to solve the problem mentioned in the background art that the opening of the intake valve of current compressors is open. Since the compressor needs to be placed outdoors for operation, most of them are only equipped with a protective net for simple isolation. When stationary, they cannot automatically close, which makes it easy for debris to enter and cause damage to the interior.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a compressor valve assembly, including an intake valve intake port, an intake chamber is provided in the middle of the intake port, a telescopic assembly is connected to the middle of the intake chamber, a first limiting ring is fixedly connected to the upper end of the telescopic assembly, a spring is provided in the lower end of the telescopic assembly, a telescopic connecting rod is connected to the middle of the telescopic assembly, the upper end of the telescopic connecting rod extends through the middle of the first limiting ring to the outside and is fixedly connected to a sealing disc, a rectangular tube is fixedly connected to the upper end of the intake port, the upper end of the telescopic connecting rod extends through the middle of the sealing disc to the upper end of the rectangular tube and is fixedly connected to a rectangular connector, and L-shaped rotating parts are connected to the front and rear ends and the middle of both sides of the rectangular tube.
[0006] Preferably, the upper and lower ends of the front and rear ends and the upper and lower ends of the left and right ends of the telescopic component are fixedly connected to the inner end face of the air intake port of the air intake valve inside the air intake chamber by fixing rods.
[0007] Preferably, a second limiting ring is fixedly connected to the lower end of the telescopic link, and the upper end of the spring is limitedly connected to the lower end of the second limiting ring.
[0008] Preferably, each of the L-shaped rotating parts is provided with a limiting groove in the middle, and each of the L-shaped rotating parts is rotatably connected to the rectangular tube through a second rotating shaft passing through the limiting groove.
[0009] Preferably, rectangular grooves are provided at the middle of both sides and the middle of both ends of the upper end of the rectangular connector.
[0010] Preferably, the upper ends of the four L-shaped rotating parts are respectively inserted into the four rectangular slots at the upper end of the rectangular connector and rotatably connected by the first rotating shaft.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] 1. In this invention, by setting up L-shaped rotating parts, L-shaped rotating parts are connected to the front and rear ends and the middle of both sides of the rectangular tube. The upper ends of the four L-shaped rotating parts are respectively inserted into the four rectangular slots on the upper end of the rectangular connector and are rotatably connected by the first rotating shaft. The upper end of the L-shaped rotating part can rotate on the upper end of the rectangular connector through the first rotating shaft. When the rectangular connector moves downward, it pulls the upper end of the L-shaped rotating part downward. At the same time, the middle part of the L-shaped rotating part rotates through the second rotating shaft, so that the lower end of the L-shaped rotating part opens outward to realize ventilation and allow the air intake port of the air intake valve to draw in air.
[0013] 2. In this invention, by setting up a telescopic component, an air intake chamber is set in the middle of the air intake port of the air intake valve, and a telescopic component is connected in the middle of the air intake chamber. A first limiting ring is fixedly connected to the upper end of the telescopic component, a spring is set in the lower end of the telescopic component, and a telescopic connecting rod is connected in the middle of the telescopic component. When the compressor stops sucking air, the spring pushes the telescopic connecting rod to move upward, and the air-closing disc abuts against the upper end of the air intake chamber to achieve air closure. At the same time, it pushes the rectangular connecting piece to move upward to reset the L-shaped rotating piece, so that the first air intake hole is automatically closed.
[0014] 3. In this invention, by setting the air-sealing disc, a telescopic connecting rod is connected to the middle of the telescopic assembly. The upper end of the telescopic connecting rod extends through the middle of the first limiting ring to the outside and is fixedly connected to the air-sealing disc. A rectangular tube is fixedly connected to the upper end of the air inlet of the air inlet valve. The upper end of the telescopic connecting rod extends through the middle of the air-sealing disc to the upper end of the rectangular tube and is fixedly connected to a rectangular connecting piece. When the compressor draws air, the air-sealing disc moves downward by the air pressure, compressing the spring. The lower end of the telescopic connecting rod retracts into the telescopic assembly, allowing the upper end of the L-shaped rotating part to rotate on the upper end of the rectangular connecting piece via the first rotating shaft. The telescopic connecting rod, as the air-sealing disc moves downward, pulls the rectangular connecting piece downward, thereby pulling the upper end of the L-shaped rotating part downward. At the same time, the middle of the L-shaped rotating part rotates via the second rotating shaft, causing the lower end of the L-shaped rotating part to open outward, thus achieving ventilation.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0021] Please see Figure 1-4An embodiment of the present invention provides a compressor valve assembly, including an intake valve intake port 1, an intake chamber 101 is provided in the middle of the intake valve intake port 1, a telescopic assembly 2 is connected to the middle of the intake chamber 101, a first limiting ring 201 is fixedly connected to the upper end of the telescopic assembly 2, a spring 202 is provided in the lower end of the telescopic assembly 2, a telescopic connecting rod 3 is connected to the middle of the telescopic assembly 2, the upper end of the telescopic connecting rod 3 extends through the middle of the first limiting ring 201 to the outside and is fixedly connected to a sealing disc 302, a rectangular tube 4 is fixedly connected to the upper end of the intake valve intake port 1, the upper end of the telescopic connecting rod 3 extends through the middle of the sealing disc 302 to the upper end of the rectangular tube 4 and is fixedly connected to a rectangular connector 303, and L-shaped rotating parts 5 are connected to the front and rear ends and the middle of both sides of the rectangular tube 4.
[0022] Furthermore, the upper and lower ends of the front and rear ends and the upper and lower ends of the left and right ends of the telescopic assembly 2 are fixedly connected to the inner end face of the air intake port 1 of the air intake valve inside the air intake chamber 101 by fixing rods 102, so that the telescopic assembly 2 remains stable inside the air intake chamber 101.
[0023] Furthermore, a second limiting ring 301 is fixedly connected to the lower end of the telescopic link 3, and the upper end of the spring 202 is limited to the lower end of the second limiting ring 301. The second limiting ring 301 is inserted into the telescopic assembly 2 for limiting and abutting the upper end of the spring 202. The spring 202 keeps the telescopic link 3 in an outward state, and allows the lower end of the telescopic link 3 to compress the spring 202 and retract into the telescopic assembly 2.
[0024] Furthermore, each L-shaped rotating component 5 is provided with a limiting groove 501 in the middle, and each L-shaped rotating component 5 is rotatably connected to the rectangular tube 4 through the limiting groove 501 via the second rotating shaft 401, so that the L-shaped rotating component 5 can rotate on the rectangular tube 4.
[0025] Furthermore, rectangular grooves 304 are provided at the middle of both sides and the middle of both ends of the upper end of the rectangular connector 303.
[0026] Furthermore, the upper ends of the four L-shaped rotating parts 5 are respectively inserted into the four rectangular slots 304 on the upper end of the rectangular connector 303 and rotatably connected by the first rotating shaft 305, so that the upper end of the L-shaped rotating part 5 can rotate on the upper end of the rectangular connector 303 through the first rotating shaft 305. When the rectangular connector 303 moves downward, it pulls the upper end of the L-shaped rotating part 5 downward. At the same time, the middle part of the L-shaped rotating part 5 rotates through the second rotating shaft 401, so that the lower end of the L-shaped rotating part 5 opens outward to realize ventilation, so that the air intake port 1 of the air intake valve can draw in air.
[0027] Working principle: In use, the intake port 1 of the intake valve is fixedly installed on the intake valve. An intake chamber 101 is located in the middle of the intake port 1. A telescopic assembly 2 is connected to the middle of the intake chamber 101. A first limiting ring 201 is fixedly connected to the upper end of the telescopic assembly 2. A spring 202 is located at the lower end of the telescopic assembly 2. A telescopic connecting rod 3 is connected to the middle of the telescopic assembly 2. A second limiting ring 301 is fixedly connected to the lower end of the telescopic connecting rod 3. The upper end of the spring 202 is limited by the lower end of the second limiting ring 301. 1. Insert the telescopic component 2 into the telescopic assembly 2 to limit its movement and press against the upper end of the spring 202. The spring 202 keeps the telescopic link 3 in an outward-extended state. The upper end of the telescopic link 3 passes through the middle of the first limiting ring 201 and extends to the outside, where it is fixedly connected to a sealing disc 302. When the telescopic link 3 is in the extended state, the sealing disc 302 presses against the upper end of the air inlet chamber 101 to achieve air sealing. The upper end of the air inlet port 1 of the air inlet valve is fixedly connected to a rectangular tube 4. The upper end of the telescopic link 3 passes through the middle of the sealing disc 302 and extends to the upper end of the rectangular tube 4, where it is fixedly connected to a rectangular tube 4. When the compressor draws in air, the suction pressure causes the air-sealing disc 302 to move downwards, compressing the spring 202. The lower end of the telescopic connecting rod 3 retracts into the telescopic assembly 2. L-shaped rotating parts 5 are connected to the front and rear ends and the middle of both sides of the rectangular tube 4. The upper ends of the four L-shaped rotating parts 5 are respectively inserted into the four rectangular slots 304 on the upper end of the rectangular connecting part 303 and are rotatably connected by the first rotating shaft 305. This allows the upper ends of the L-shaped rotating parts 5 to rotate on the upper end of the rectangular connecting part 303 via the first rotating shaft 305. The telescopic connecting rod 3 moves downwards as the air-sealing disc 302 moves downwards. The movement causes the rectangular connector 303 to move downwards, which in turn pulls the upper end of the L-shaped rotating part 5 downwards. At the same time, the middle part of the L-shaped rotating part 5 rotates through the second rotating shaft 401, causing the lower end of the L-shaped rotating part 5 to open outwards, allowing air to pass through and enabling the air intake port 1 of the air intake valve to draw in air. When the air intake stops, the spring 202 pushes the telescopic connecting rod 3 to move upwards, and the air-closing disc 302 abuts against the upper end of the air intake chamber 101 to close the air. At the same time, the rectangular connector 303 is pushed upwards to reset the L-shaped rotating part 5, causing the first air intake hole to close automatically.
[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
