Description

Technical Field

[0001] This utility model relates to the field of air compressor pipeline drainage technology, specifically an air compressor pipeline drainage control device. Background Technology

[0002] An air compressor is a device used to compress gases. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating piston type, using rotating vanes or a rotating screw to deliver air into pipes to expel liquids from the pipes. This method is efficient and fast.

[0003] The existing Chinese utility model patent with publication number CN207093340U discloses an automatic drainage device for air compressor pipelines, including an air delivery pipe and a gas-liquid separator. The gas-liquid separator is located on one side of the air delivery pipe, with one end fixedly connected to the air delivery pipe; the air delivery pipe is located on one side of the air compressor and is fixedly connected to the air compressor; one end of the gas-liquid separator is equipped with a drain ball valve, a connecting elbow, a filter box, and a timer valve; the drain ball valve is located at one end of the gas-liquid separator and is fixedly connected to the gas-liquid separator; the connecting elbow is located below the drain ball valve, with one end fixedly connected to the drain ball valve and the other end fixedly connected to the filter box; the filter box is located on one side of the connecting elbow and is fixedly connected to the connecting elbow; the timer valve is located on one side of the filter box and is fixedly connected to the filter box. This utility model controls the ball valve through a timer switch, thereby achieving the purpose of timed drainage. Simultaneously, filtration is performed during the drainage process, allowing the discharged water resources to be recycled, saving resources for enterprises and reducing labor costs.

[0004] After the air compressor starts, it will continuously supply air into the pipeline. The air pressure inside the pipeline will increase over time. When the air pressure exceeds the set safety range, if it is not vented in time, it will cause damage to the equipment, and in severe cases, it may even cause an accident. At the same time, existing air compressors are generally connected to the pipeline through ball valves. Due to the sealing of ball valves, water leakage may occur when the water pressure inside the pipeline is too high. Utility Model Content

A limit ring is fixedly installed at the front end of the spring, a limit block is fixedly installed inside the connecting pipe, a one-way valve is inserted inside the limit block, a protective shell is inserted above the connecting pipe, a drive motor is inserted inside the protective shell, a base is fixedly installed below the drive motor, a gear is fixedly installed on the outside of the drive motor shaft, a gear ring is fixedly installed on the outside of the transmission plate, a top cover is fixedly installed at the top of the protective shell, a PLC controller is fixedly installed above the top cover, and a solenoid valve is fixedly installed above the limit pipe; the transmission plate facilitates the gear ring to drive the valve core to rotate.

[0009] As a preferred embodiment of this utility model, the connecting pipe has a three-way structure, the connecting pipe is connected to the limiting pipe, and the air pressure sensor extends through the connecting pipe into the interior of the connecting pipe; the connecting pipe can limit the position of the valve seat.

[0011] As a preferred embodiment of this utility model, the valve seat is installed symmetrically on the front and rear sides of the valve core, and the connecting ring, valve seat and connecting pipe form a sliding connection. The limiting ring on the rear side of the valve core is fixedly connected to the connecting pipe. The valve seat can clamp the valve core to achieve a sealing function.

[0012] As a preferred embodiment of this utility model, the spring is located between the connecting ring and the limiting ring, and the limiting ring on the front side of the valve core and the connecting pipe form a sliding connection; the connecting ring can limit the position of the valve seat.

[0013] As a preferred embodiment of this utility model, the rear end of the one-way valve is fixedly connected to the limiting ring on the front side of the valve core through a threaded structure, and the one-way valve and the limiting block form a sliding connection; the limiting block can restrict the position of the one-way valve.

[0015] Compared with the prior art, the present invention provides a compressed air pipeline drainage control device, which has the following beneficial effects:

[0016] 1. This utility model, through the setting of a pressure sensor, connects the connecting pipe to the liquid delivery pipeline when the valve core rotates to the point where the opening is engaged with the valve seat. At this time, the air pressure inside the connecting pipe is consistent with the air pressure in the liquid delivery pipeline. After the air compressor starts, gas enters the gas delivery pipeline through the connecting pipe. The pressure sensor monitors the air pressure inside the connecting pipe and the liquid delivery pipeline and transmits the monitoring data to the PLC controller. The PLC controller compares the monitoring data of the pressure sensor with the air pressure threshold. When the monitoring data exceeds the air pressure threshold, the PLC controller will control the solenoid valve to open, thereby allowing the air inside the pipeline to be discharged to the outside through the solenoid valve. This method can avoid the pipeline bursting due to excessive air pressure inside the pipeline.

[0017] 2. This utility model utilizes a one-way valve, which is inserted into the center of the limiting block and forms a sliding connection with it. The one-way valve allows gas to pass from back to front. The rear end of the one-way valve is connected to the limiting ring on the front side of the valve core via a threaded structure. When the opening of the valve core does not match the opening of the valve seat, the liquid inside the pipe will exert a backward force on the limiting block through the one-way valve. This causes the one-way valve to move the limiting block backward, compressing the spring and causing it to contract. When the spring contracts, it applies a force towards the valve core to the connecting ring, clamping the valve seat with the valve core. This increases the fit between the valve seat and the valve core, thereby increasing the sealing performance of the device and preventing liquid leakage. Attached Figure Description

A solenoid valve 121 is fixedly installed above the limit pipe 1.

[0027] The connecting pipe 11 has a three-way structure and is connected to the limiting pipe 1. The air pressure sensor 12 extends through the connecting pipe 11 into the interior of the connecting pipe 11.

[0028] The fixed tube 13 is connected to the connecting tube 11 via a threaded structure, and the cap 16 is connected to the fixed tube 13 via a threaded structure.

[0029] The valve seat 19 is mirror-symmetrically installed on the front and rear sides of the valve core 14. The connecting ring 18, the valve seat 19 and the connecting pipe 11 form a sliding connection. The limiting ring 111 on the rear side of the valve core 14 is fixedly connected to the connecting pipe 11.

[0030] Spring 110 is located between connecting ring 18 and limiting ring 111, and the limiting ring 111 on the front side of valve core 14 and connecting pipe 11 form a sliding connection.

[0031] The rear end of the one-way valve 113 is fixedly connected to the limiting ring 111 on the front side of the valve core 14 through a threaded structure, and the one-way valve 113 and the limiting block 112 form a sliding connection.

[0032] The drive motor 115 passes through the bottom surface of the protective shell 114, the base 116 is fixedly connected to the connecting pipe 11, and the gear 117 and the gear ring 118 mesh with each other.

[0033] Specifically, the limiting tube 1 can limit the position of the solenoid valve 121, the connecting tube 11 can limit the position of the valve seat 19, the air pressure sensor 12 can monitor the air pressure inside the connecting tube 11, the fixing tube 13 can limit the position of the packing 15, the packing 15 can play a sealing role, the cover 16 can squeeze the packing 15, the transmission plate 17 can facilitate the toothed ring 118 to drive the valve core 14 to rotate, the connecting ring 18 can limit the position of the valve seat 19, the valve seat 19 can clamp the valve core 14 to play a sealing role, the limiting ring 111 can limit the position of one end of the spring 110, and the one-way valve. 113 can drive the limit block 112 to move, the protective shell 114 can protect the gear 117 and the gear ring 118, the drive motor 115 can drive the gear 117 to rotate, the base 116 can support the drive motor 115, the gear 117 can drive the gear ring 118 to rotate, the gear ring 118 can drive the transmission plate 17 to rotate, the top cover 119 can seal the upper end of the protective shell 114, the PLC controller 120 can control the opening and closing of the solenoid valve 121 according to the monitoring data of the air pressure sensor 12, and the solenoid valve 121 can facilitate pressure relief.

[0034] During use, when the valve core 14 rotates to engage with the valve seat 19, the connecting pipe 11 connects to the liquid delivery pipeline. At this time, the air pressure inside the connecting pipe 11 is consistent with the air pressure in the liquid delivery pipeline. After the air compressor starts, gas enters the gas delivery pipeline through the connecting pipe 11. The air pressure sensor 12 monitors the air pressure inside the connecting pipe 11 and the liquid delivery pipeline and transmits the monitoring data to the PLC controller 120. The PLC controller 120 compares the monitoring data from the air pressure sensor 12 with the air pressure threshold. When the monitoring data exceeds the air pressure threshold, the PLC controller 120 will control the solenoid valve 121 to open, thereby venting the air inside the pipeline to the outside through the solenoid valve 121. This method can prevent the pipeline from bursting due to excessive air pressure inside the pipeline. A one-way valve 113 is inserted and installed in the center of the limiting block 112, and forms a sliding connection with the limiting block 112. The one-way valve 113 allows gas to pass from back to front. The rear end of the one-way valve 113 is connected to the limiting ring 111 on the front side of the valve core 14 through a threaded structure. When the opening of the valve core 14 does not match the opening of the valve seat 19, the liquid inside the pipeline will exert a backward force on the limiting block 112 through the one-way valve 113, thereby causing the one-way valve 113 to drive the limiting block 112 to move backward and compress the spring 110, causing the spring 110 to contract. When the spring 110 contracts, it will exert a force on the connecting ring 18 pointing towards the valve core 14, clamping the valve seat 19 with the valve core 14, thereby increasing the degree of engagement between the valve seat 19 and the valve core 14. This method can increase the sealing performance of the device and prevent liquid leakage.
