Description

Technical Field

[0001] This application relates to the field of air distribution of air compressors, and particularly to an air distribution box for an air compressor. Background Art

[0002] Air compressors are common gas compression means in many industries such as industrial manufacturing, energy, refrigeration and air conditioning. Their main function is to increase air pressure to improve storage efficiency or air flow rate. In the actual use of air compressors, usually one or two large air compressors are used to supply compressed air to multiple devices.

[0003] In order to effectively manage and allocate the compressed air output by the air compressor to achieve efficient utilization and reasonable distribution of compressed air. An air distribution box is often used to distribute air, and the operator adjusts by controlling the control valve in the air distribution box to achieve the control of each individual air circuit.

[0004] In view of the above related technologies, in the existing air distribution box, it is divided into control by solenoid valves or manual valves. When the components in the distribution box need to be repaired due to faults, it is necessary to cut off the air circuit between the air distribution box and the air compressor to facilitate subsequent maintenance of the inside of the air distribution box. Utility Model Content

[0005] In order to facilitate the repair of the air distribution box that fails during use and enable it to continue to work normally, this application provides an air distribution box for an air compressor.

[0006] This application provides an air distribution box for an air compressor, adopting the following technical solutions:

[0007] An air distribution box for an air compressor includes a box body. An air inlet pipe is provided on one side of the box body. A number of manual reversing valves connected to the air inlet pipe are provided inside the box body. A number of solenoid valves corresponding to the manual reversing valves one by one are provided inside the box body. The manual reversing valve is provided with a first air outlet and a second air outlet. The first air outlet is connected to the solenoid valve. The box body is provided with a number of air delivery joints leading to the air-using equipment. Both the solenoid valve and the second air outlet are connected to the air delivery joints. An air pressure detection component for detecting the real-time air pressure is provided inside the box body.

[0008] By adopting the above technical solutions, during normal use, the manual reversing valve is in a state of connecting the air inlet pipe and the first air outlet. The operator controls the on-off of different air delivery joints by controlling the solenoid valve. When the solenoid valve needs to be repaired, the operator closes the pipeline between the solenoid valve and the air delivery joint and connects the manual reversing valve to the second air outlet. At this time, the related air-using equipment can still be effectively supplied with air.

[0009] Optionally, a buffer air tank is provided inside the box, and the buffer air tank is located between the intake pipe and the manual reversing valve.

[0010] By adopting the above technical solution, after the air compressor is transported into the air distribution box, it first passes through the buffer air tank. The buffer air tank can buffer the fluctuating compressed air output by the air compressor, thereby reducing the flow pulsation in the entire air circuit.

[0011] Optionally, a gas-liquid separator is provided on the side of the intake pipe away from the main pressure regulator, and a weighing platform is provided outside the box, and the gas-liquid separator is located on the weighing platform.

[0012] By adopting the above technical solution, the gas-liquid separator removes the small amount of liquid that may remain in the compressed air output by the air compressor to the rear, thereby preventing the liquid from accumulating at the buffer air tank and the solenoid valve in the air distribution box and damaging the relevant components. By measuring the weight change of the gas-liquid separator by the measuring platform to judge the water storage inside, when the water storage is too much, all solenoid valves are closed to prevent the liquid overflowing from the gas-liquid separator from entering the air distribution box.

[0013] Optionally, there are multiple intake pipes, and the box is provided with a main pressure regulator, and the main pressure regulator is located between the intake pipe and the buffer air tank.

[0014] By adopting the above technical solution, when multiple air compressors are used simultaneously, the corresponding main pressure regulator is opened and the air pressure input into the air distribution box is adjusted to input compressed air with a suitable air pressure into the air distribution box. When it stops being used, only the main pressure regulator connected to it needs to be closed.

[0015] Optionally, the buffer air tank is detachably connected to the inner wall of the box. The buffer air tank and the main pressure regulator are both provided with quick-release joints, and the connection between the manual reversing valve and the buffer air tank is a threaded connection.

[0016] By adopting the above technical solution, when maintenance is required for the buffer air tank and the manual reversing valve, the buffer air tank is removed from the inner wall, and the manual reversing valve that needs to be replaced alone is replaced.

[0017] Optionally, the air pressure detection component includes several barometers. The barometers are provided with adjustable throttle valves. There is a box door on one side of the box, and the barometers are fixedly connected to the box door. The intake end of the air supply joint is connected to the barometer.

[0018] By adopting the above technical solution, the individual air pressure is detected by the barometer, and the air pressure output by each air supply joint is adjusted by adjusting the adjustable throttle valve on the barometer to achieve the suitable air pressure for each gas-using device.

[0019] Optionally, the box door is provided with indicator lights corresponding one by one to the electromagnetic valves. The box door is provided with an observation window for observing the corresponding manual reversing valve. The observation window and the indicator light are respectively located on both sides of the corresponding gas transmission joint.

[0020] By adopting the above technical solutions, the operator can observe the state of the manual reversing valve through the observation window to judge whether its air outlet is controlled by the electromagnetic valve, and judge whether there is compressed air passing through the corresponding gas transmission joint by judging the opening and closing state of the electromagnetic valve through the indicator light.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. During normal use, the manual reversing valve is in the state of connecting the air inlet pipe and the first air outlet. The operator controls the on-off of different gas transmission joints by controlling the electromagnetic valve. When the electromagnetic valve needs to be overhauled, the operator closes the pipeline between the electromagnetic valve and the gas transmission joint and connects the manual reversing valve to the second air outlet. At this time, the relevant equipment using gas can still be effectively supplied with gas;

[0023] 2. After the air compressor is transported into the air distribution box, it first passes through the buffer air tank. The buffer air tank can buffer the fluctuating compressed air output by the air compressor, thereby reducing the flow pulsation in the entire gas circuit. Description of the Drawings

Detailed Description of the Invention

[0028] The following further describes the present application in detail with reference to all the drawings.

[0029] The embodiment of the present application discloses an air distribution box for an air compressor.

[0030] Refer to Figures 1 to 3, An air distribution box for an air compressor, comprising a box body 1. An air inlet pipe 5 is provided on one side of the box body 1. A number of manual reversing valves 3 connected to the air inlet pipe 5 are provided inside the box body 1. A number of electromagnetic valves 4 corresponding to the manual reversing valves 3 one by one are provided inside the box body 1. The manual reversing valve 3 is provided with a first air outlet 31 and a second air outlet 32. The first air outlet 31 is connected to the electromagnetic valve 4. The box body 1 is provided with a number of air delivery joints 131 leading to the air-using equipment. Both the electromagnetic valve 4 and the second air outlet 32 are connected to the air delivery joints 131. A air pressure detection component for detecting the real-time air pressure is provided inside the box body 1. During normal use, the manual reversing valve 3 is in a state of connecting the air inlet pipe 5 and the first air outlet 31. The operator controls the on-off of different air delivery joints 131 by controlling the electromagnetic valve 4. When it is necessary to repair the electromagnetic valve 4, the operator closes the pipeline between the electromagnetic valve 4 and the air delivery joint 131 and connects the manual reversing valve 3 and the second air outlet 32. At this time, the related air-using equipment can still be effectively supplied with air.

[0031] Since the air compressor commonly uses a piston type to compress air, there is a certain flow fluctuation in the output air. In order to make the air pressure output by the air distribution box stable, it is necessary to cancel out the flow pulsation generated by the air compressor as much as possible. A buffer air tank 2 is provided inside the box body 1. The buffer air tank 2 is located between the air inlet pipe 5 and the manual reversing valve 3. After the air compressor is transported into the air distribution box, it first passes through the buffer air tank 2. The buffer air tank 2 can buffer the fluctuating compressed air output by the air compressor, thereby reducing the flow pulsation in the entire air circuit.

[0032] Since there may be a small amount of moisture remaining in the compressed air discharged by the air compressor, after long-term use, more moisture may accumulate in the air distribution box. In order to separate the air and the moisture in it. A gas-liquid separator 121 is provided on the side of the air inlet pipe 5 away from the main pressure regulating valve 11. A weighing platform 12 is provided outside the box body 1. The gas-liquid separator 121 is located on the weighing platform 12. The gas-liquid separator 121 removes the small amount of liquid that may remain in the compressed air output by the air compressor backward, thereby preventing the liquid from accumulating at the buffer air tank 2 and the electromagnetic valve 4 in the air distribution box and damaging the related components. The weight change of the gas-liquid separator 121 is measured by the measuring platform to judge the water storage inside. When the water storage is too much, all the electromagnetic valves 4 are closed to prevent the liquid overflowing from the gas-liquid separator 121 from entering the air distribution box.

[0033] The gas-liquid separator 121 is a relatively mature technology, and those skilled in the art can easily know its usage method and installation method.

[0034] In order to control and distribute multiple air compressors through an air distribution box. There are multiple intake pipes 5, and the box body 1 is provided with a main pressure regulating valve 11, and the main pressure regulating valve 11 is located between the intake pipe 5 and the buffer air tank 2. When multiple air compressors are used simultaneously, the corresponding main pressure regulating valve 11 is opened and the air pressure input into the air distribution box is adjusted so that compressed air with a suitable air pressure is input into the air distribution box. When it stops being used, only the main pressure regulating valve 11 connected thereto needs to be closed.

[0035] The buffer air tank 2 is detachably connected to the inner wall of the box body 1. Both the buffer air tank 2 and the main pressure regulating valve 11 are provided with quick-release joints, and the connection between the manual reversing valve 3 and the buffer air tank 2 is a threaded connection. When maintenance is required for the buffer air tank 2 and the manual reversing valve 3, the buffer air tank 2 is removed from the inner wall, and the manual reversing valve 3 that needs to be replaced individually is replaced.

[0036] In order to detect and adjust the pressure of each output joint. The air pressure detection component includes several air pressure gauges 132. The air pressure gauges 132 are provided with adjustable throttle valves. There is a box door 13 on one side of the box body 1. The air pressure gauges 132 are fixedly connected to the box door 13, and the connection is made between the intake end of the air delivery joint 131 and the air pressure gauge 132. The air pressure is detected separately by the air pressure gauge 132, and the air pressure output by each air delivery joint 131 is adjusted by adjusting the adjustable throttle valve on the air pressure gauge 132 to achieve a suitable air pressure for each gas-using device.

[0037] In order to enable the operator to quickly and timely detect the working states of the manual reversing valve 3 and the solenoid valve 4. The box door 13 is provided with indicator lights 14 corresponding to the solenoid valves 4 one by one. The box door 13 is provided with an observation window 133 for observing the corresponding manual reversing valve 3. The observation window 133 and the indicator light 14 are respectively located on both sides of the corresponding air delivery joint 131. The operator can observe the state of the manual reversing valve 3 through the observation window 133 to judge whether its air outlet is controlled by the solenoid valve 4, and judge whether there is compressed air passing through the corresponding air delivery joint 131 by the opening and closing state of the indicator light 14 for the solenoid valve 4.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
