Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to a series constant pressure device for air compressors. Background Art

[0002] During the air compression process of the air compressor, the water vapor in the air will be compressed. When the air cools, the water vapor will condense into water. These water droplets are deposited at the bottom of the gas tank. If they are not removed in time, they will accumulate into a large amount of water. This water will corrode the gas tank and the inner wall of the pipeline, and in severe cases, it will damage the pneumatic equipment.

[0003] After the existing air compressor inputs the compressed air into the air tank, the compressed air is stably supplied from the air tank to the gas-consuming equipment. Since the water vapor in the compressed air will condense in the air tank to form water accumulation, the water accumulation in the air tank needs to be manually opened at regular intervals to drain the water, which is not safe and inefficient.

[0004] The existing patent (Announcement No.: CN201858138U) is an automatic drainage device for an air compressor gas tank. This utility model does not require manual timed drainage, has high safety, high efficiency, simple structure, low cost, high reliability and long service life.

[0005] In view of the above problems, existing patents have provided solutions. However, in actual use, since a single gas storage tank is used for drainage, the pressure cannot be kept constant, resulting in large gas loss and frequent inspection and maintenance.

[0006] For this purpose, a constant pressure device connected in series with an air compressor is proposed. Utility Model Content

The connecting pipe is arranged between the three ball valves and is connected to the drain pipe through the ball valve. The PB-68 automatic drain valve is arranged on one side of the connecting pipe. The drain port is arranged at the drain end of the PB-68 automatic drain valve. The diameters of the ball valve and the connecting pipe are both 15 mm.

[0010] Preferably, three slip knots are provided on one side of the connecting pipe for facilitating maintenance of the connecting pipe, and the diameter of the slip knot is 15 mm.

The drain pipe 2 is arranged at the bottom of the air storage tank 1 and is connected to the air storage tank 1. A constant pressure component 3 is arranged on one side of the drain pipe 2.

[0028] The constant pressure assembly 3 includes a ball valve 301, a connecting pipe 302, a PB-68 automatic drain valve 303 and a drain outlet 304. The three ball valves 301 are respectively arranged at one end of the three drain pipes 2 away from the gas storage tank 1. The connecting pipe 302 is arranged between the three ball valves 301 and is connected to the drain pipe 2 through the ball valve 301. The PB-68 automatic drain valve 303 is arranged on one side of the connecting pipe 302. The drain outlet 304 is arranged at the drain end of the PB-68 automatic drain valve 303. The diameters of the ball valve 301 and the connecting pipe 302 are both 15 mm.

[0030] When in use, multiple gas tanks 1 are connected in series through the connecting pipe 302, and then a ball valve 301 is installed on each gas tank 1 to control the constant pressure. The PB-68 automatic drain valve 303 is used to automatically drain the water, so that the connecting pipe 302 and the inside of the gas tank 1 reach a constant pressure, reducing the gas loss of the gas tank 1. At the same time, the slip knots 401 set at multiple positions solve the problem of pressure loss of a single gas tank 1 due to maintenance, thereby effectively reducing the loss of a single gas, reducing the cost of spare parts replacement and maintenance, and ensuring the constant pressure of each gas tank 1.

[0031] Specifically, Figure 3 As shown, pressure regulators 402 for assisting pressure control are provided at the connection points between the three ball valves 301 and the connecting pipes 302 .

[0036] By adopting the above technical solution, the problem that the existing automatic drainage device of the air compressor gas tank 1 cannot maintain constant pressure during actual use, resulting in large gas loss and frequent inspection and maintenance due to the drainage of a single gas tank 1 is solved.

[0037] When the present application is used, firstly, multiple gas storage tanks 1 are connected in series through the connecting pipe 302, and then a ball valve 301 is installed on each gas storage tank 1 to control the constant pressure. The PB-68 automatic drain valve 303 is used to automatically drain the water, so that the connecting pipe 302 and the inside of the gas storage tank 1 can reach a constant pressure, thereby reducing the gas loss of the gas storage tank 1. At the same time, the slip knots 401 arranged at multiple positions solve the problem of pressure loss of a single gas storage tank 1 due to maintenance, thereby effectively reducing the loss of a single gas, reducing the cost of replacement of spare parts and maintenance, and ensuring the effect of constant pressure of each gas storage tank 1. The pressure regulator 402 can be used for auxiliary To assist in controlling pressure, when the PB-68 automatic drain valve 303 drains water through the drain port 304, the water will first filter out impurities through the filter plate 405 to prevent clogging of the drain pipe 2, and then be discharged into the external drainage system through the guide pipe 404 at the bottom of the storage bin 403 to prevent pollution to the surrounding environment. The support plate 406 and the support groove 407 can support the drain pipe 2. When the water flows inside the connecting pipe 302, it will pass through the filter bin 408 and the filter core 409. The filter bin 408 and the filter core 409 will filter out large impurities in the water flow to prevent clogging of the PB-68 automatic drain valve 303.
