Description

Technical Field

[0001] The utility model relates to the technical field of large-channel compressor air valves, in particular to an air valve for a large-channel compressor. Background Art

[0002] A compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It draws low-temperature, low-pressure refrigerant gas from the intake pipe, compresses it through the motor-driven piston, and discharges high-temperature, high-pressure refrigerant gas into the exhaust pipe, providing power for the refrigeration cycle.

[0003] The existing high-speed compressor air valve (application number: 202321975720.0) requires the compressor to operate continuously to maintain pressure, resulting in increased power consumption and energy waste. The stability of the high-speed compressor air valve is improved, but the above still exists. When the compressor is in use, the air valve is its important component. The setting of the air valve can relieve pressure when the internal pressure of the compressor is too high. The above device can make the sealing gasket press tightly through the elastic force of the spring to avoid air leakage during normal operation. However, since the spring will be compressed during pressure relief, the spring will be repeatedly compressed and rebounded during long-term use, which can easily lead to the deterioration of the spring rebound effect, and thus easily lead to the failure of sealing work. It is inconvenient to adjust the pressure given by the spring to the bottom, and when connecting the device to the pressure relief hole of the compressor, it is not convenient to perform double sealing on the connection position, which can easily lead to air leakage at the connection position, affecting normal use. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art of being inconvenient to adjust the pressure applied by the spring to the lower part, easily affecting the sealing work when the spring rebound effect becomes poor, and being inconvenient to perform double sealing on the connection position, which in turn easily leads to air leakage at the connection position, affecting normal use, and to propose a gas valve for a large-channel compressor.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A gas valve for a large-channel compressor is designed, comprising a shell, an oblique cylinder fixedly connected to the lower inner wall of the shell, a vertical cylinder fixedly connected to the bottom inner wall of the shell, a rubber threaded sleeve fixedly connected to the lower outer wall of the vertical cylinder, a curved block is gap-fitted in the groove above one side of the inner wall of the shell, and an adjustment structure is provided on one side of the shell.

[0007] The top of the lever is connected to the top of the lever, and the bottom of the lever is connected to the spring which has the advantage of being easily movable. The push-pull hook at the bottom of the lever is furthermore arranged to move relative to the top of the lever when the lever is in motion.

[0008] Preferably, a through hole is processed on the inner wall of one end of the shell.

[0009] Preferably, a circular plate three is fixedly connected to the bottom of the shell.

[0010] Preferably, a rubber ring is fixedly connected to the bottom of the circular plate three.

[0011] Preferably, the inner wall of the rubber ring is fixedly connected to the outer wall of the vertical cylinder.

[0012] The utility model proposes a large-channel compressor air valve, which has the following beneficial effects: through the cooperation of the shell, the vertical cylinder, the curved block, the inclined cylinder and the adjustment structure, the device can be used to rotate the screw rod, the screw rod drives the plate body to move downward, and the plate body compresses the spring. At this time, the spring drives the circular plate 1 to move downward, and the circular plate 1 and the inclined cylinder clamp the rubber block. At the same time, the circular plate 1 drives the vertical rod to move downward, and the vertical rod drives the circular plate 2 to move downward. The circular plate squeezes the rubber pad, thereby facilitating the adjustment of the pressure applied by the spring to the lower side, thereby avoiding the influence of the spring rebound effect on the sealing work when the spring rebound effect deteriorates.

[0013] Through the cooperation of the shell, vertical cylinder, rubber threaded sleeve, circular plate and rubber ring, when the device is in use, the shell can be rotated to rotate the rubber threaded sleeve, and the rubber threaded sleeve can be screwed into the pressure relief hole of the compressor. The rubber threaded sleeve can achieve one-side sealing. At the same time, after being screwed in, the rubber ring fits with the position around the pressure relief hole of the compressor to achieve secondary sealing, which is convenient for double sealing of the connection position, avoiding air leakage at the connection position and affecting normal use.

The rubber threaded sleeve 6 plays a sealing role, and a curved block 9 is fitted in the groove gap above one side of the inner wall of the shell 1.

[0024] A through hole 3 is processed on the inner wall of one end of the shell 1, and the through hole 3 is used for gas discharge. A circular plate 3 8 is fixedly connected to the bottom of the shell 1, and a rubber ring 7 is fixedly connected to the bottom of the circular plate 3 8. The rubber ring 7 plays a sealing role. The inner wall of the rubber ring 7 is fixedly connected to the outer wall of the vertical tube 5. An adjustment structure 2 is provided on one side of the shell 1. The adjustment structure 2 is convenient for adjusting the pressure given by the spring 2a4 below to avoid affecting the sealing work when the rebound effect of the spring 2a4 deteriorates.

[0025] The adjustment structure 2 includes a screw rod 2a1, the upper portion of the outer wall of the screw rod 2a1 is threadedly connected to the top inner wall of the housing 1, and the bottom of the screw rod 2a1 is rotatably connected to the plate body 2a2 through a bearing. The bearing enables the screw rod 2a1 to rotate on the top of the plate body 2a2 when a force is applied. One side of the top of the plate body 2a2 is fixedly connected to the bottom of the curved block 9, and a rod body 2a3 is gap-fitted in the inner wall of one side of the plate body 2a2. The bottom of the rod body 2a3 is fixedly connected to a circular plate 2a5, and the bottom of the circular plate 2a5 is fixedly connected to a rubber block 2a6, which acts as a seal.

[0026] The bottom of the rubber block 2a6 fits with the top of the oblique cylinder 4, the bottom of the circular plate 1 2a5 is fixedly connected to the vertical rod 2a7, the upper outer wall of the vertical rod 2a7 is gapped with the inner wall of the oblique cylinder 4, the bottom of the vertical rod 2a7 is fixedly connected to the circular plate 2a8, the bottom of the circular plate 2a8 is fixedly connected to the rubber pad 2a9, the bottom of the rubber pad 2a9 fits with the top of the vertical cylinder 5, and the lower outer wall of the rod body 2a3 is gapped with the spring 2a4, the spring 2a4 applies downward force to the circular plate 1 2a5, and the upper and lower ends of the spring 2a4 are fixedly connected to the bottom side of the plate body 2a2 and the top side of the circular plate 1 2a5, respectively, to facilitate the adjustment of the pressure applied by the spring 2a4 to the lower side, so as to avoid affecting the sealing work when the rebound effect of the spring 2a4 deteriorates.

[0027] Working principle:

[0028] When using the air valve of a large channel compressor;

[0029] Rotate the shell 1, and then rotate the rubber threaded sleeve 6, screw the rubber threaded sleeve 6 into the pressure relief hole of the large channel compressor, and the rubber threaded sleeve 6 can achieve one-side sealing. At the same time, after being screwed in, the rubber ring 7 fits around the pressure relief hole of the large channel compressor, thereby achieving secondary sealing, and thus achieving the installation and fixation of the shell 1. When the air pressure in the large channel compressor is too high, the gas pushes the rubber pad 2a9 upward, and the rubber pad 2a9 drives the circular plate 2a8 to move upward, and the circular plate 2a8 drives the vertical rod 2a7 to move upward, and the vertical rod 2a7 drives the circular plate 1 2a5 to move upward. The circular plate 2a5 compresses the spring 2a4. At this time, the rubber pad 2a9 separates from the vertical cylinder 5, and the rubber block 2a6 separates from the top of the inclined cylinder 4, allowing the gas to leak out and be discharged through the through hole 3, thereby achieving pressure relief. After the pressure is reduced, the spring 2a4 rebounds, thereby restoring the rubber pad 2a9 and the rubber block 2a6 to their original positions. When the rebound force of the spring 2a4 is insufficient, the screw rod 2a1 is rotated, and the screw rod 2a1 drives the plate 2a2 to move downward. The plate 2a2 compresses the spring 2a4, thereby causing the spring 2a4 to exert sufficient downward force on the circular plate 2a5 to ensure the sealing effect.

[0030] Example 2:

[0031] Refer to the attached Figure 1-6 : In this embodiment, a gas valve for a large-channel compressor is provided, wherein the regulating structure 2 may further include an outer shell 2b1, the bottom of the outer shell 2b1 is fixedly connected to the top of the shell 1, and the top inner wall of the outer shell 2b1 is threadedly connected to a cover plate 2b2.

[0032] Working principle:

[0033] The cover plate 2b2 is rotated to make the cover plate 2b2 enter the top inner wall of the housing 2b1, thereby shielding the screw rod 2a1 and preventing the screw rod 2a1 from being accidentally touched and affecting the sealing work.

[0034] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
