Description

Technical Field

[0001] This utility model relates to the field of compressor technology, specifically to a pressure valve structure for a compressor. Background Technology

[0002] A compressor is a driven fluid machine that raises 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. In a compressor system, the pressure valve plays a crucial role; it is responsible for regulating and controlling the internal pressure of the compressor, ensuring stable and efficient operation.

[0003] For example, the national authorized patent announcement number CN216078461U discloses a minimum pressure valve for a compressor, including: a valve body, an air inlet at the bottom of the valve body, an exhaust port on one side of the bottom of the valve body, a valve core slidably connected inside the valve body, the valve core slidably connected between the air inlet and the exhaust port, a valve cover installed on the top of the valve body, a central through hole in the middle of the valve cover, an adjusting screw at the central through hole, one end of the adjusting screw extending into the valve body, and the adjusting screw and the valve core connected by a spring. Compared with the prior art, the advantages of this utility model are: the valve body is set into two parts, the valve body and the valve cover, which facilitates disassembly and maintenance; the adjusting screw for controlling the pressure is installed on the valve cover, which facilitates adjustment when the spring pressure decreases, so as to control the normal pressure value and ensure the effective separation of compressed air and lubricating oil; the original three valves and three springs are replaced by one valve and one spring, which simplifies the structure, facilitates processing, and enhances reliability.

[0004] However, the pressure valve structure of the compressor mentioned above lacks an effective anti-clogging structure. Because the compressor's working environment is complex, the intake air may contain dust, impurities, oil, etc., which can easily accumulate in the valve port, valve core, and other parts, resulting in a reduction in the flow area of ​​the pressure valve. This, in turn, affects the accuracy of pressure regulation and the overall performance of the compressor. Furthermore, the pressure valve generates a lot of noise when discharging air, which can affect the surrounding environment. Utility Model Content

[0005] The present invention aims to solve the problems mentioned in the background art by providing a pressure valve structure for a compressor.

[0006] The specific technical solution is as follows:

[0007] A pressure valve structure for a compressor includes: a valve body, an inlet and an outlet respectively provided on both sides of the valve body, the inlet being used to connect to the outlet end of the compressor, an anti-clogging component being detachably installed inside the inlet, and a resistive muffler being welded inside the outlet, with a grid installed on one end of the inner wall of the resistive muffler.

[0008] As a preferred embodiment of this utility model, one end of the air inlet is provided with an installation groove, and the inner surfaces of both the air inlet and the air outlet are coated with an epoxy coating.

[0009] As a preferred embodiment of this utility model, the anti-blocking component includes a positioning pin, a mounting cylinder, and a fixing bolt. The positioning pin is fixedly installed on the inner wall of the mounting groove in a circumferential array. The mounting cylinder is detachably installed at one end of the air inlet. The fixing bolt is used to fix the mounting cylinder on the air inlet.

[0010] As a preferred embodiment of this utility model, the mounting cylinder has positioning holes arranged in a circular array at one end of its outer periphery, and connecting plates are fixedly installed on both sides of the inner wall of the mounting groove. The upper surface of the connecting plate has a threaded hole at one end, and the surface of the mounting cylinder has two sets of notches at one end.

[0011] In a preferred embodiment of this utility model, the mounting cylinder is inserted into the air inlet so that the notch surface is in contact with one end of the connecting plate surface, and the fixing bolt is inserted into the threaded hole for fixation.

[0012] As a preferred embodiment of this utility model, a filter screen is provided inside the mounting cylinder.

[0013] This utility model has the following beneficial effects:

[0014] 1. The pressure valve structure of the compressor provided by this utility model, through the design of the air inlet, anti-clogging component, and resistive silencer, allows the anti-clogging component inside the valve body to filter impurities in the gas when it enters the pressure valve from the outlet end. This ensures that impurities do not accumulate at the air inlet of the valve body and affect its later use. The anti-clogging component is also easy to disassemble and clean. The resistive silencer reduces the noise generated during gas discharge, lowering the noise level when the pressure valve discharges gas. The grid installed inside the resistive silencer prevents airflow turbulence, ensuring that it does not affect the surrounding environment. Furthermore, by applying an epoxy coating to the air inlet and outlet, it can effectively resist corrosive components that may be contained in the gas, ensuring the long-term stable operation of the pressure valve.

[0015] 2. The pressure valve structure of the compressor provided by this utility model, through the design of positioning pins, mounting cylinders, and connecting plates, facilitates the precise positioning and fixing of the mounting cylinder through the cooperation of positioning pins and positioning holes, making it easy to disassemble and assemble. Then, the two sets of notches on the surface of the mounting cylinder fit into the connecting plates on both sides of the inner wall of the mounting groove. After that, the fixing bolts are inserted into the threaded holes on the upper surface of the connecting plate, thereby firmly fixing the mounting cylinder to the air inlet. Then, the impurities in the gas are intercepted by the filter screen provided on the inner wall of the mounting cylinder, which can reduce the impact of impurities in the gas on the inside of the pressure valve and ensure that the pressure valve is not affected by its performance during use.

[0029] Example 1

[0030] The pressure valve structure of the compressor provided in this embodiment is as follows: Figures 1-5 As shown, it includes: a valve body 1, with an inlet 101 and an outlet 102 on both sides of the valve body 1. The inlet 101 is used to connect to the outlet end of the compressor. An anti-clogging component 2 is detachably installed inside the inlet 101. A resistive silencer 3 is welded inside the outlet 102. A grid 301 is installed on one end of the inner wall of the resistive silencer 3. An installation groove 103 is provided at one end of the inlet 101. The inner surfaces of both the inlet 101 and the outlet 102 are coated with an epoxy coating.

[0031] Through the design of the air inlet 101, the anti-clogging component 2, and the resistive silencer 3, when the gas in the compressor enters the pressure valve from the outlet, the anti-clogging component 2 installed in the valve body 1 can filter impurities in the gas, ensuring that impurities will not accumulate at the air inlet 101 of the valve body 1 and affect later use. The anti-clogging component 2 is easy to disassemble and clean. The resistive silencer 3 can reduce the noise emitted when the gas is discharged, lowering the noise level when the pressure valve discharges gas. The grid 301 installed in the resistive silencer 3 can prevent airflow turbulence, ensuring that it will not affect the surrounding environment. Furthermore, by applying an epoxy coating to the air inlet 101 and the air outlet 102, it can effectively resist corrosive components that may be contained in the gas, ensuring the long-term stable operation of the pressure valve.

[0032] Example 2

[0033] The pressure valve structure of the compressor provided in this embodiment is as follows: Figures 4-5 As shown, the anti-clogging component 2 includes a positioning pin 201, a mounting cylinder 203, and a fixing bolt 205. The positioning pin 201 is fixedly installed in a circular array on the inner wall of the mounting groove 103. The mounting cylinder 203 is detachably installed at one end of the air inlet 101. The fixing bolt 205 is used to fix the mounting cylinder 203 to the air inlet 101. Positioning holes 206 are formed in a circular array at one end of the outer periphery of the mounting cylinder 203. Connecting plates 202 are fixedly installed on both sides of the inner wall of the mounting groove 103. A threaded hole is formed at one end of the upper surface of the connecting plate 202. Two sets of notches are formed at one end of the surface of the mounting cylinder 203. The mounting cylinder 203 is inserted into the air inlet 101, so that the notch surface fits against one end of the surface of the connecting plate 202. The fixing bolt 205 is inserted into the threaded hole for fixation. A filter screen 204 is provided inside the mounting cylinder 203.

[0034] The design of the positioning pin 201, mounting cylinder 203, and connecting plate 202 facilitates the precise positioning and fixation of the mounting cylinder 203 through the cooperation of the positioning pin 201 and positioning hole 206, making it easy to disassemble and assemble. Then, the two sets of notches on the surface of the mounting cylinder 203 fit into the connecting plate 202 on both sides of the inner wall of the mounting groove 103. After that, the fixing bolt 205 is inserted into the threaded hole on the upper surface of the connecting plate 202, thereby firmly fixing the mounting cylinder 203 to the air inlet 101. Then, the filter screen 204 provided on the inner wall of the mounting cylinder 203 intercepts impurities in the gas, which can reduce the impact of impurities in the gas on the inside of the pressure valve and ensure that the performance of the pressure valve is not affected during use.

[0035] In summary, the pressure valve structure of the compressor provided in this embodiment has the following advantages: it can effectively filter the gas entering the pressure valve from the compressor, prevent impurities in the gas from accumulating inside, reduce the impact, ensure that the adjustment accuracy and performance of the pressure valve are not significantly affected, and reduce the noise impact during gas discharge.

[0036] In use, the mounting cylinder 203 is installed into the air inlet 101 by aligning the positioning hole 206 provided on the mounting cylinder 203 with the positioning pin 201 in the mounting groove 103 in the air inlet 101 at one end of the valve body 1. Then, the connecting plate 202 is inserted into the mounting cylinder 203 by fixing bolts 205 to connect it with the notch surface of the mounting cylinder 203, which facilitates disassembly and assembly. When the gas in the compressor enters the valve body 1, it can effectively intercept impurities in the gas, thereby reducing the risk of wear on the internal components of the pressure valve, avoiding blockage failure, improving sealing performance, and ensuring safe operation.
