Description

Technical Field

[0001] The utility model relates to the field of air compressors, in particular to an air pressure regulating component of an air compressor. Background Art

[0002] An air compressor is a device used to compress air into high-pressure gas. They are commonly used in many industrial and commercial applications, such as supplying factory equipment, driving tools, control systems, and in some cases, even providing a clean air supply. By reducing the volume of air and increasing its pressure, air compressors enable more efficient energy storage and can provide additional power support. Different types of air compressors can be implemented using various configurations and principles, such as screw, piston, and centrifugal. Their applications range from automotive repair and construction engineering to medical equipment.

[0003] In the existing technology, although a certain gas compression effect can be achieved during use, there is a defect: the existing air compressor lacks the pressure regulation effect of gas outlet in various situations, resulting in the inability to adjust the gas outlet in various situations. The outlet effect is single and cannot be adapted to different working environments. In view of this, we propose an air pressure regulation component for an air compressor to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to address the problems existing in the background technology and to propose an air pressure regulating assembly for an air compressor.

[0005] The technical solution of the utility model is as follows: an air pressure regulating assembly of an air compressor, comprising a box body, an air outlet pipe and a branch pipe, an air inlet being fixed on one side of the box body, an air outlet pipe being provided on the other side of the box body, a control valve 1 being provided on the main part of the air outlet pipe, a control valve 2 being rotatably mounted on one side of the control valve 1, a control valve 3 being rotatably mounted on one side of the control valve 2, and a branch pipe being provided on one side of the air outlet pipe;

[0006] When the device is in use, after the cooling system and the compressor are turned on, gas can enter from the air inlet, and the double helix structure inside the box is driven by a motor to compress the gas and discharge it from the outlet pipe. There are three valves at the outlet pipe, namely control valve one, control valve two and control valve three. The corresponding rotating plates one, two and three have different gas permeabilities. Rotating them to the maximum open state allows the gas to pass through quickly. When rotated to the end face, the gas will pass through the through holes of the three. When the on-off valve set in the outlet pipe is opened, the gas will be discharged directly at the current maximum flow rate. The flow rate can only be controlled through control valve one, two and three. When the on-off valve is closed, the flow direction of the gas will move from the branch pipe. The branch pipe is provided with a quantitative valve. The quantitative valve can ensure that the width of the gas passage is constant. Compared with the movement of the main pipe, a certain pressure will be increased to eject. Such a design can achieve the adjustment effect of different pressure ejections, which has high practicality.

[0007] Preferably, a quantitative valve is provided in the middle of the branch pipe, and an opening and closing valve is provided in the main pipe of the air outlet pipe.

[0008] Preferably, an air storage tank is fixed to the upper end of the box body, and a cooling system is fixed to one side of the air outlet pipe.

[0009] Preferably, a pressure gauge is fixed on one side of the upper end of the box body, and a compressor is fixed on the other side of the upper end of the box body.

[0010] Preferably, a roller is rotatably mounted on the lower end of the box, and a motor is fixed to an outer wall of one side of the box.

[0011] Preferably, a rotating plate 1 is rotatably installed inside the air outlet pipe, and the rotating plate 1 is rotatably connected to the control valve 1. A rotating plate 2 is rotatably installed inside the air outlet pipe, and the rotating plate 2 is rotatably connected to the control valve 2. A rotating plate 3 is rotatably installed inside the air outlet pipe, and the rotating plate 3 is rotatably connected to the control valve 3.

[0012] Preferably, one through hole is opened on the first surface of the rotating plate, two through holes are opened on the second surface of the rotating plate, and three through holes are opened on the third surface of the rotating plate.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] 1. The utility model can adjust the gas flow rate by utilizing the rotating plates 1, 2 and 3 connected in series inside the designed outlet pipe, thereby achieving the variable pressure outlet effect of the gas after the same pressure treatment inside the box.

[0015] 2. Based on the first beneficial effect, the device can use the quantitative valve designed with the branch pipe to achieve a fixed passage width effect, thereby achieving a higher pressure gas outlet effect after the opening and closing valve is opened.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Next, the present invention is described in detail with reference to schematic diagrams.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] See also Figures 1-4 As shown, this embodiment is an air pressure regulating assembly of an air compressor, including a housing 1, an air outlet pipe 2 and a branch pipe 11. An air inlet 6 is fixed to one side of the housing 1, and an air outlet pipe 2 is provided on the other side of the housing 1. A control valve 14 is provided on the main part of the air outlet pipe 2. A control valve 2 1715 is rotatably mounted on one side of the control valve 14. A control valve 3 is rotatably mounted on one side of the control valve 2 1715. A branch pipe 11 is provided on one side of the air outlet pipe 2.

[0029] When the device is in use, after the cooling system 4 and the compressor 9 are turned on, the gas can enter from the air inlet 6, and the motor 8 drives the double helix structure inside the box 1 to compress the gas and discharge it from the outlet pipe 2. There are three valves at the outlet pipe 2, namely the control valve 1 14, the control valve 2 1715 and the control valve 3. The corresponding rotating plates 13, 2 16 and 3 18 have different gas permeabilities. Rotating them to the maximum open state allows the gas to pass quickly. When rotating to the end face, the gas will be discharged from one of the three valves. When the opening and closing valve 12 provided in the outlet pipe 2 is opened, the gas will be discharged directly at the current maximum flow rate, and the flow rate can only be controlled by the control valve 14, the control valve 2 1715 and the control valve 3. When the opening and closing valve 12 is closed, the flow direction of the gas will move from the branch pipe 11. The branch pipe 11 is provided with a quantitative valve 10. The quantitative valve 10 can ensure that the width of the gas passage is constant. Compared with the movement of the main pipe, a certain pressure will be increased to eject. Such a design can achieve the adjustment effect of different pressure ejections, which has high practicality.

[0030] Example 2

[0031] See also Figures 1-4 As shown, this embodiment is based on embodiment 1 and further includes: a metering valve 10 is provided in the middle of the branch pipe 11, and an on-off valve 12 is provided on the main pipe of the outlet pipe 2. The metering valve 10 is a valve body that can fix the width of the gas passing through. Its width is smaller than the passing width of the outlet pipe 2 when the on-off valve 12 is opened, that is, the flow rate of the gas under the same pressure of the metering valve 10 is greater than when the on-off valve 12 is opened. When the on-off valve 12 is opened, the metering valve 10 can be rotated to the closed state, and when the on-off valve 12 is closed, the metering valve 10 can be opened to an appropriate opening.

[0032] An air storage tank 5 is fixed to the upper end of the box body 1, and a cooling system 4 is fixed to one side of the air outlet pipe 2. The air storage tank 5 can store a certain amount of compressed air to help provide a stable air supply, so as to avoid a rapid drop or fluctuation in system pressure during sudden demand. The cooling system 4 can ensure the stability of the operating temperature of the device.

[0033] A pressure gauge 3 is fixed on one side of the upper end of the box body 1, and a compressor 9 is fixed on the other side of the upper end of the box body 1. The pressure gauge 3 can detect the pressure of the gas compression inside the device when the gas is discharged, and the compressor 9 can assist in compressing the gas and passing it into the interior of the box body 1.

[0034] A roller 7 is rotatably mounted on the lower end of the box body 1 , and a motor 8 is fixed to the outer wall of one side of the box body 1 . The motor 8 can drive the double helix structure inside the box body 1 to compress the gas.

[0035] A rotating plate 13 is rotatably installed inside the air outlet pipe 2, and the rotating plate 13 is rotatably connected to the control valve 14. A rotating plate 2 is rotatably installed inside the air outlet pipe 2, and the rotating plate 2 16 is rotatably connected to the control valve 2 1715. A rotating plate 3 18 is rotatably installed inside the air outlet pipe 2, and the rotating plate 3 18 is rotatably connected to the control valve 3. The rotating plates 13, 16 and 18 can adjust the gas flow rate inside the air outlet pipe 2, thereby achieving air pressure regulation.

[0036] A through hole is opened on the surface of rotating plate 13, two through holes are opened on the surface of rotating plate 2 16, and three through holes are opened on the surface of rotating plate 3 18. Different through holes have different gas flow rates under the same initial pressure state, achieving different pressure outlet adjustment effects.
