Description

Technical Field

[0001] This utility model relates to the field of air pipe connector technology, specifically to a pressure stabilization and adjustment structure for an air braking system pipeline. Background Technology

[0002] The pressure stabilization and regulation structure of the automotive air brake system is a key component to ensure the safe and reliable operation of the braking system. It uses a series of devices and components to regulate the pressure of compressed air to a suitable range and maintain pressure stability under different operating conditions.

[0003] Existing pneumatic braking systems mostly rely on an air compressor to deliver compressed air to an air tank. When the air pressure in the tank reaches the upper limit, the pressure regulating valve closes, and the air compressor stops working. When the air pressure in the tank drops to the lower limit due to braking, the pressure regulating valve opens, and the air compressor restarts to replenish the air pressure in the tank. The air tank's internal storage space is a single unit. When the internal air pressure rises or falls, the pressure regulating device needs to be constantly adjusted to ensure the stability of the gas during delivery. This not only affects the service life of the regulating device but also causes fluctuations in the gas during delivery. In contrast, pneumatic braking systems use a pressure regulator to stabilize the delivered air pressure. However, the diaphragm and spring in the regulator have a certain degree of flexibility and cannot quickly and timely stabilize the pressure. Moreover, after prolonged use, the diaphragm and spring will experience metal fatigue, reducing the accuracy of air pressure regulation.

[0004] Therefore, there is an urgent need for a pressure stabilization and regulation structure for air braking system pipelines to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a pressure stabilization and regulation structure for a pneumatic braking system pipeline, addressing the problems mentioned in the background section. Most existing pneumatic braking system pipeline pressure stabilization and regulation structures rely on an air compressor to deliver compressed air to an air reservoir. When the air pressure in the reservoir reaches a set upper limit, the pressure regulating valve closes, and the air compressor stops working. When the air pressure in the reservoir drops to a set lower limit due to braking operation, the pressure regulating valve opens, and the air compressor restarts to replenish the air pressure in the reservoir. Since the air reservoir's internal storage space is a single unit, the pressure regulating device needs to continuously adjust to ensure gas stability during delivery when the internal pressure rises or falls. This not only affects the lifespan of the regulating device but also causes fluctuations in gas pressure during delivery. While pneumatic braking systems use a pressure regulator to stabilize the delivered air pressure, the diaphragm and spring in the regulator have limited flexibility, preventing rapid and timely pressure regulation. Furthermore, after prolonged use, the diaphragm and spring experience metal fatigue, reducing the accuracy of pressure regulation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure stabilization and regulation structure for a pneumatic braking system pipeline, comprising an air reservoir, with a second air pressure sensor and an air inlet pipe respectively provided at both ends of the air reservoir, the second air pressure sensor and the air inlet pipe respectively penetrating both ends of the air reservoir, an air delivery pipe provided on the surface of the air reservoir, the air delivery pipe respectively penetrating both ends of the air reservoir, a one-way valve provided on the surface of the air delivery pipe, the one-way valve having an axisymmetric structure about the air reservoir, and a first air pressure sensor provided on the surface of the air delivery pipe; further comprising a constant pressure component, the constant pressure component being disposed inside the air reservoir for maintaining a constant output air pressure of the air reservoir; and an adjustment component, the adjustment component being disposed on the surface of the air delivery pipe for precisely controlling the air pressure in the system pipeline.

[0007] Furthermore, the constant pressure component includes a fixed sleeve, which is fixedly connected to the inner wall of the gas storage cylinder. The fixed sleeve is provided with a movable seat, which is movably connected to the fixed sleeve. The inner wall of the fixed sleeve is provided with an array of guide grooves, and the surface of the movable seat is fixed with an array of guide blocks, which are movably connected to the guide grooves.

[0008] Furthermore, mounting slots are provided on both sides of the movable seat, and an electric telescopic rod is provided between the movable seat and the air storage cylinder. The two ends of the electric telescopic rod are fixedly connected to the air storage cylinder and the mounting slot, respectively, and the electric telescopic rod has an axisymmetric structure about the fixed sleeve.

[0009] Furthermore, annular grooves are respectively provided at both ends of the fixed sleeve and the movable seat, and sealing rings are provided in the annular grooves. The sealing rings are made of thermoplastic rubber, and elastic sheets are glued between the sealing rings.

[0010] Furthermore, the adjustment assembly includes an adjustment seat, the surface of which is provided with a connecting groove that extends through the adjustment seat, a partition is fixed inside the connecting groove, the bottom surface of which is provided with a movable groove, and the bottom surface of which is provided with a vent hole that extends through the bottom surface of the adjustment seat.

[0011] Furthermore, the movable groove is provided with an adjusting block, and the adjusting block is movably connected to the movable groove. The adjusting block passes through the partition. An adjusting motor is fixed on the top surface of the adjusting seat. An adjusting screw is fixed at the output end of the adjusting motor, and the adjusting screw is threadedly connected to the adjusting block.

[0012] Furthermore, the adjusting block has an array of movable channels, which pass through the top and bottom surfaces of the adjusting block. The movable channels are equipped with movable supports, which are movably connected to the movable channels. A limit block is fixed at the top of the movable support, and a return spring is fixed between the limit block and the adjusting block.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model discloses a pressure stabilization and adjustment structure for a pneumatic braking system pipeline. A constant pressure component is installed in the air storage cylinder. Within the constant pressure component, a fixed sleeve and a movable seat divide the space within the air storage cylinder into equal spaces. Then, under the action of symmetrical electric telescopic rods, the gas in one space is compressed, and the gas in the other space is replenished through the inlet pipe. When the air storage cylinder delivers gas through the gas delivery pipe, the gas pressure in the space where the gas is being delivered decreases. At this time, under the compression of the constant pressure component, the gas pressure in the space where the gas is being delivered remains constant. This design makes the gas delivery process more stable, reduces the impact on the system pipeline, and extends the service life of the structure.

An adjustment component is provided on the surface of the air supply pipe. In the adjustment component, the connecting groove in the adjustment seat delivers gas, and a partition is provided in the connecting groove. Driven by the adjustment motor, the adjustment screw can adjust the distance between the adjustment block and the partition, thereby quickly and accurately adjusting the air pressure in the pipeline. Moreover, when the air pressure in the pipeline is too high, the gas will squeeze the movable support downward through the movable channel, and then the gas will be discharged through the venting channel in the movable support, thereby reducing the pressure on the pipeline. This design improves the accuracy of air pressure adjustment in the system pipeline and enhances the practicality of the structure. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-10 This utility model provides a pressure stabilization and adjustment structure for a pneumatic braking system pipeline, including an air storage cylinder 4. A second air pressure sensor 8 and an air inlet pipe 6 are respectively installed at both ends of the air storage cylinder 4, with the second air pressure sensor 8 and the air inlet pipe 6 passing through both ends of the air storage cylinder 4. An air delivery pipe 5 is provided on the surface of the air storage cylinder 4, and the air delivery pipe 5 passes through both ends of the air storage cylinder 4. A one-way valve 3 is provided on the surface of the air delivery pipe 5, and the one-way valve 3 has an axisymmetric structure about the air storage cylinder 4. A first air pressure sensor 7 is also provided on the surface of the air delivery pipe 5. The system also includes a constant pressure component 1, which is disposed inside the air storage cylinder 4 to maintain a constant output air pressure; and an adjustment component 2, which is disposed on the surface of the air delivery pipe 5 to precisely control the air pressure in the system pipeline.

[0019] Specifically, when the structure is working, an external air compressor can be connected to the air storage tank 4 through the air intake pipe 6 to increase the air pressure inside the air storage tank 4. Then, under the action of the constant pressure component 1, the gas in one space of the air storage tank 4 is delivered to the system pipeline through the air delivery pipe 5 and the one-way valve 3. Then, the gas is stably delivered to the pipeline through the adjustment component 2. The first air pressure sensor 7 can monitor the air pressure at the adjustment component 2, while the second air pressure sensor 8 can monitor the air pressure inside the air storage tank 4.

[0020] The constant pressure assembly 1 includes a fixed sleeve 103, which is fixedly connected to the inner wall of the gas storage tank 4. A movable seat 104 is provided inside the fixed sleeve 103 and is movably connected to the fixed sleeve 103. Guide grooves 106 are arrayed on the inner wall of the fixed sleeve 103. Guide blocks 108 are arrayed and fixed on the surface of the movable seat 104, and the guide blocks 108 are movably connected to the guide grooves 106. Mounting grooves 105 are respectively provided on both sides of the movable seat 104. An electric telescopic rod 101 is provided between the movable seat 104 and the air storage cylinder 4. The two ends of the electric telescopic rod 101 are fixedly connected to the air storage cylinder 4 and the mounting groove 105, respectively. The electric telescopic rod 101 has an axisymmetric structure about the fixed sleeve 103. The fixed sleeve 103 and the movable seat 104 are respectively provided with annular grooves 109. A sealing ring 107 is provided in the annular groove 109. The sealing ring 107 is made of rubber thermoplastic. An elastic sheet 102 is pasted between the sealing rings 107.

[0021] Specifically, in the constant pressure component 1, the fixed sleeve 103 and the movable seat 104 divide the space in the gas storage cylinder 4 into equal spaces. Then, under the action of the symmetrical electric telescopic rod 101, the gas in one space is compressed, and the gas in the other space is replenished through the air inlet pipe 6. When the gas storage cylinder 4 transports gas through the gas delivery pipe 5, the gas pressure in the space where the gas is transported will decrease. At this time, under the compression of the constant pressure component 1, the gas pressure in the space where the gas is transported will remain constant. This design makes the gas more stable during the transport process, reduces the impact on the system pipeline, and extends the service life of the structure.

[0022] The adjustment assembly 2 includes an adjustment base 201. A connecting groove 202 is formed on the surface of the adjustment base 201, and the connecting groove 202 penetrates the adjustment base 201. A partition 206 is fixed inside the connecting groove 202. A movable groove 203 is formed on the bottom surface of the connecting groove 202. A vent hole 204 is formed on the bottom surface of the movable groove 203, and the vent hole 204 penetrates the bottom surface of the adjustment base 201. An adjustment block 207 is provided in the movable groove 203, and the adjustment block 207 is movably connected to the movable groove 203, and the adjustment block 207 penetrates the partition 206. An adjustment motor 213 is fixed on the top surface of the adjustment base 201, and an adjustment pin is fixed at the output end of the adjustment motor 213. A lead screw 205 is provided, and the lead screw 205 is threadedly connected to the adjusting block 207. The adjusting block 207 has an array of movable channels 210, which pass through the top and bottom surfaces of the adjusting block 207. A movable bracket 209 is provided in the movable channel 210, and the movable bracket 209 is movably connected to the movable channel 210. A limit block 212 is fixed at the top of the movable bracket 209. A return spring 211 is fixed between the limit block 212 and the adjusting block 207. A venting channel 208 is provided inside the movable bracket 209, and the venting channel 208 passes through the top surface of the limit block 212 and the side surface of the movable bracket 209.

[0023] Specifically, in the regulating component 2, the connecting groove 202 in the regulating seat 201 transports gas, and the connecting groove 202 is equipped with a partition 206. Driven by the regulating motor 213, the regulating screw 205 can adjust the distance between the regulating block 207 and the partition 206, thereby quickly and accurately regulating the gas pressure in the pipeline. Moreover, when the gas pressure in the pipeline is too high, the gas will squeeze the movable support 209 downward through the movable channel 210, and then the gas will be discharged through the venting channel 208 in the movable support 209, thereby reducing the pressure on the pipeline. This design improves the accuracy of gas pressure regulation in the system pipeline and enhances the practicality of the structure.

[0024] Working principle: In the constant pressure component 1, the fixed sleeve 103 and the movable seat 104 divide the space in the gas storage cylinder 4 into equal spaces. Then, under the action of the symmetrical electric telescopic rod 101, the gas in one space is compressed, and the gas in the other space is replenished through the air inlet pipe 6. When the gas storage cylinder 4 delivers gas through the gas delivery pipe 5, the gas pressure in the space where the gas is delivered will decrease. At this time, under the compression of the constant pressure component 1, the gas pressure in the space where the gas is delivered will remain constant. The elastic sheet 102 between the sealing rings 107 can deform during the movement of the movable seat 104, ensuring that the spaces on both sides of the fixed sleeve 103 are not connected. The design of the mounting groove 105 not only reduces the weight of the constant pressure component 1, but also increases the gas storage space. In the regulating component 2, the connecting groove 202 in the regulating seat 201 delivers gas, and the connecting groove 202 is provided with a partition 206. Driven by the regulating motor 213, the regulating screw 205 can adjust the distance between the regulating block 207 and the partition 206, thereby quickly and accurately adjusting the gas pressure in the pipeline. Moreover, when the gas pressure in the pipeline is too high, the gas will squeeze the movable support 209 downward through the movable channel 210, and then the gas will be discharged through the venting channel 208 in the movable support 209, thereby reducing the pressure on the pipeline.

[0025] When the structure is working, an external air compressor can be connected to the air storage tank 4 through the air intake pipe 6 to increase the air pressure inside the air storage tank 4. Then, under the action of the constant pressure component 1, the gas in one space of the air storage tank 4 is delivered to the system pipeline through the air delivery pipe 5 and the one-way valve 3. Then, the gas is stably delivered to the pipeline through the adjustment component 2. The first air pressure sensor 7 can monitor the air pressure at the adjustment component 2, while the second air pressure sensor 8 can monitor the air pressure inside the air storage tank 4.
