Description

Technical Field

[0001] The utility model relates to the technical field of compressor exhaust valves, in particular to a valve for increasing the exhaust volume of a compressor. Background Art

[0002] The compressor exhaust valve is a critical component. As the piston compresses gas within the cylinder, the pressure within the cylinder gradually increases. When the pressure reaches a certain value, it overcomes the resistance of the exhaust valve spring, opening the valve and allowing the gas to be discharged. As the piston continues to move, the pressure within the cylinder drops. When the pressure drops below the exhaust pipe pressure, the spring closes the valve, preventing the exhausted gas from flowing back into the cylinder and ensuring the normal operation and stability of the compressor. Traditional exhaust valves are installed deep within the compressor pipe, making them difficult to remove and inconvenient to replace. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-4 As shown, a gas valve for increasing the exhaust volume of a compressor comprises an end cover 1, a connecting assembly 2 is provided at the lower portion of the end cover 1, and an exhaust valve assembly 3 is provided at the lower portion of the connecting assembly 2.

[0020] In this embodiment, the connecting assembly 2 includes an upper pressure ring 201, a lower pressure ring 202 and an exhaust groove 203. A plurality of exhaust grooves 203 are arranged at equal intervals in the lower part of the lower pressure ring 202. The upper periphery of the lower pressure ring 202 is arranged inside the lower side of the upper pressure ring 201. The upper end of the upper pressure ring 201 is fixedly connected to the middle part of the lower side of the end cover 1. The lower end of the exhaust groove 203 is arranged on the upper part of the exhaust valve assembly 3. A filter screen is installed inside the lower pressure ring 202, and the filter screen is aligned with the exhaust groove 203.

[0021] Specifically, due to the movable connection between the upper pressure ring 201 and the lower pressure ring 202, when the end cover 1 is installed on the compressor exhaust port, the upper pressure ring 201 presses on the lower pressure ring 202, and the lower pressure ring 202 presses on the exhaust valve assembly 3, thereby pressing the exhaust valve assembly 3 on the compressor exhaust port. The upper pressure ring 201 and the lower pressure ring 202 are not fixedly connected, so that the exhaust valve assembly 3 can be movable to ensure normal exhaust action. After removing the end cover 1, the exhaust valve assembly 3 can be directly pulled out from the compressor exhaust port through the connecting assembly 2, which is convenient for replacing the exhaust valve assembly 3.

[0022] In this embodiment, the exhaust valve assembly 3 includes a base 301, multiple air inlets 302, a bolt 303, an upper cover 304, multiple springs 305, multiple sliding blocks 306, multiple grooves 307, multiple exhaust ports 309, a gasket 310, a nut 311 and an air cushion 312. The lower end of the bolt 303 is fixedly connected to the middle of the base 301, and the multiple air inlets 302 are evenly spaced in the middle of the base 301 and arranged on the periphery of the bolt 303. One side of the multiple sliding blocks 306 is evenly spaced and fixedly connected to the upper part of the air cushion 312. The outer periphery of the other side of the sliding block 306 is slidably connected to the inside of the groove 307. The multiple grooves 307 and the multiple exhaust ports 309 are opened. It is located in the middle of the upper cover 304 and the groove 307 and the exhaust port 309 are staggered with each other. The spring 305 is arranged inside the groove 307. The middle part of the upper cover 304 is slidably connected to the outer periphery of the bolt 303. The gasket 310 and the nut 311 are arranged on the upper part of the bolt 303. The nut 311 is arranged on the upper part of the gasket 310. A rubber pad is provided on the side of the air cushion 312 close to the base 301. A glue point 308 is installed on the inner wall of the groove 307. The glue point 308 is arranged on the end of the spring 305 away from the sliding block 306. A limiting block 314 is provided inside the air cushion 312. A limiting groove 313 is provided in the middle of the base 301. The limiting block 314 corresponds to the limiting groove 313.

[0023] Specifically, multiple sliding blocks 306 slide inside the groove 307, so that the air cushion 312 can move up and down smoothly between the upper cover 304 and the base 301, preventing it from tilting and ensuring the stability of operation. When the air pressure in the cylinder is too high, the gas will enter between the base 301 and the upper cover 304 through the air inlet 302, so that the air cushion 312 is pushed open, allowing the gas to pass through the through hole in the middle of the air cushion 312 and finally be discharged through the exhaust port 309. After the air pressure in the cylinder is reduced, the spring 305 will push the sliding block 306, so that the air cushion 312 is reset, thereby blocking the air inlet 302.

[0024] Working principle:

[0025] The plurality of sliding blocks 306 slide inside the groove 307, so that the air cushion 312 can move up and down smoothly between the upper cover 304 and the base 301, preventing it from tilting and ensuring the stability of operation. When the air pressure in the cylinder is too high, the gas will enter between the base 301 and the upper cover 304 through the air inlet 302, so that the air cushion 312 is pushed open, so that the gas passes through the through hole in the middle of the air cushion 312 and is finally discharged through the exhaust port 309. When the air pressure in the cylinder is reduced, the spring 305 will push the sliding block 306 to reset the air cushion 312, thereby resetting the air inlet 302. 2 is sealed. Due to the movable connection between the upper pressure ring 201 and the lower pressure ring 202, when the end cover 1 is installed on the exhaust port of the compressor, the upper pressure ring 201 presses on the lower pressure ring 202, and the lower pressure ring 202 presses on the exhaust valve assembly 3, thereby pressing the exhaust valve assembly 3 to the exhaust port of the compressor. The upper pressure ring 201 and the lower pressure ring 202 are not fixedly connected, so that the exhaust valve assembly 3 can be movable to ensure normal exhaust action. After removing the end cover 1, the exhaust valve assembly 3 can be directly pulled out from the exhaust port of the compressor through the connecting assembly 2, which is convenient for replacing the exhaust valve assembly 3.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
