[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, by using a telescopic pipe sleeve in combination with a counterweight balance mechanism, etc., the counterweight balance mechanism is used to balance the pressure of the pipeline system. When the pressure in the pipeline system is high, the pressure can cause the telescopic pipe sleeve to expand, and a part of the gas enters the telescopic pipe sleeve to stabilize the air pressure. When the pressure in the pipeline system is low, the counterweight can press the gas in the telescopic pipe sleeve into the pipeline system.

When in use, the air inlet connecting pipe is connected to the air inlet pipe, and the exhaust connecting pipe is connected to the exhaust pipe. At this time, the pressure in the pipeline will lift the corrugated pipe, and then the screw rod is rotated. The rotating screw rod drives the piston to move, and the moving piston can press the counterweight liquid in the second box body into the first box body, thereby increasing the weight above the support plate, making the counterweight above the support plate balance with the pressure of the pipeline system. In this way, by continuously adding liquid into the first box body, the weight above the support plate can be accurately set.

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] Please refer to Figures 1 - 8 , a pipeline pressure stabilizing device for oil and gas storage and transportation, including an intake connection pipe 1 and an exhaust connection pipe 2. One end of each of the intake connection pipe 1 and the exhaust connection pipe 2 is fixedly connected to a seat box 3, and a telescopic pipe sleeve 4 is detachably connected to the upper surface of the seat box 3. One end of each of the intake connection pipe 1 and the exhaust connection pipe 2 penetrates through the seat box 3 and communicates with the telescopic pipe sleeve 4. The upper end of the telescopic pipe sleeve 4 is detachably connected to a support plate 5, and a weight balance mechanism is arranged above the support plate 5. A protective cover 6 is fixedly connected to the upper surface of the seat box 3, and the protective cover 6 is sleeved outside the telescopic pipe sleeve 4. The upper end of the protective cover 6 is detachably connected to a sealing cover 7, and a gas guiding and limiting component is arranged inside the protective cover 6.

[0020] It can be seen from the above structure that: by setting the telescopic pipe sleeve 4 and using it in conjunction with the counterweight balancing mechanism, the counterweight balancing mechanism is used to balance the pressure of the pipeline system. When the pressure of the pipeline system is high, the pressure can make the telescopic pipe sleeve 4 larger, and a part of the gas enters the telescopic pipe sleeve 4 to stabilize the air pressure. When the pressure in the pipeline system is low, the counterweight can press the gas in the telescopic pipe sleeve 4 into the pipeline system to stabilize the pipeline system. Not only is the structure simple and reliable, but the space in the telescopic pipe sleeve 4 can be changed, so that the device can store and release a large amount of gas like a gas storage tank that cooperates with a compressor, and thus there is no need to make the tank body very large to meet the use requirements, thereby making the device very practical. At the same time, the device is safe and reliable when in use. As long as the structure of the telescopic pipe sleeve 4 is not damaged, the device will not have leakage problems.

[0021] Furthermore, the telescopic tube sleeve 4 includes a bellows 401, and the two ends of the bellows 401 are respectively fixedly connected with a first flange ring 402 and a second flange ring 403, the first flange ring 402 is detachably connected to the seat box 3, and the second flange ring 403 is detachably connected to the support plate 5; by arranging the bellows 401, the first flange ring 402 and the second flange ring 403 for use in combination, the bellows 401 can be telescoped, thereby changing the space inside the bellows 401.

[0022] Furthermore, the counterweight balancing mechanism includes a first box body 8 fixedly connected to the support plate 5, and the outer wall of the first box body 8 is sleeved with a plurality of counterweight blocks 9, the upper surface of the sealing cover 7 is provided with a clearance groove, and the inner wall of the clearance groove is fixedly connected to the second box body 10, the upper surface of the second box body 10 is detachably connected to a sealing plate 11, and the inner wall of the second box body 10 is slidably connected to a piston 12, the upper surface of the piston 12 is fixedly connected to a fixing ring 13, and the inner wall of the fixing ring 13 is rotatably connected to a screw rod 14, one end of the screw rod 14 passes through the sealing plate 11 and extends to the outside of the sealing plate 11, and the screw rod 14 is threadedly connected to the sealing plate 11, the lower surface of the second box body 10 is connected to a hose 15, and one end of the hose 15 is connected to the first box body 8; by setting the counterweight balancing mechanism, the second box body 10 is connected to the upper surface of the second box body 10, and the upper surface of the second box body 10 is connected to the sealing plate 11, and the upper surface of the second box body 10 is connected to the sealing plate 11. The weight block 9, the first box body 8 and the second box body 10 are used together. Before use, different numbers of counterweight blocks 9 are installed according to the pressure of the pipeline system, and counterweight liquid is injected into the second box body 10. When in use, the intake connecting pipe 1 is connected to the intake pipe, and the exhaust connecting pipe 2 is connected to the exhaust pipe. At this time, the pressure in the pipeline will press the bellows 401, and then rotate the screw rod 14. The rotating screw rod 14 drives the piston 12 to move. The moving piston 12 can press the counterweight liquid in the second box body 10 into the first box body 8, thereby increasing the weight above the support plate 5, so that the counterweight above the support plate 5 is balanced with the pressure of the pipeline system. In this way, by continuously adding liquid to the first box body 8, the weight above the support plate 5 can be accurately set.

[0023] Further, the air guiding and limiting assembly includes a plurality of support columns 16 arranged in the protective cover 6. One end of each support column 16 is slidably sleeved with a limiting tube 17. One end of one of the limiting tubes 17 is fixedly connected to an electromagnetic valve 18, and the electromagnetic valve 18 is fixedly connected to the sealing cover 7. One ends of the remaining limiting tubes 17 are fixedly connected to the sealing cover 7. An air guiding hole 19 is formed at one end of the support column 16. A through hole is formed in one side wall of the sealing cover 7, and the inner wall of the through hole is fixedly connected to a detector 20. The outer wall of the sealing cover 7 is fixedly connected to a controller 21. The detector 20 is electrically connected to the controller 21, and the controller 21 is electrically connected to the electromagnetic valve 18. A connecting block 22 is slidably sleeved on the outer wall of the support column 16, and one side wall of the connecting block 22 is fixedly connected to the support plate 5. By arranging the limiting tube 17 and the support column 16 to cooperate with each other, the support plate 5 can be limited to ensure the stability of the support plate 5 during movement. At the same time, by arranging the air guiding hole 19 and the electromagnetic valve 18 to cooperate with each other, the protective cover 6 is communicated with the outside, avoiding the formation of high pressure or negative pressure in the protective cover 6 and affecting the operation of the device. At the same time, by arranging the detector 20 and the controller 21 to cooperate with each other, when the corrugated pipe 401 leaks, the leaked gas will enter the protective cover 6. When the detector 20 detects the leaked gas, the detector 20 can control the electromagnetic valve 18 to close through the controller 21, so that the protective cover 6 forms a sealed space, preventing the gas from leaking out, and thus improving the safety of the device.

[0024] Further, a hopper 23 is fixedly connected to the inner wall of the seat box 3, and the hopper 23 is communicated with the telescopic pipe sleeve 4. One end of the hopper 23 is communicated with a sewage discharge pipe 24, and one end of the sewage discharge pipe 24 is threadedly connected with a sealing plug 25. By arranging the sewage discharge pipe 24 and the sealing plug 25 to cooperate with each other, if liquid impurities enter the telescopic pipe sleeve 4, the liquid impurities will flow into the hopper 23. When there are too many liquid impurities, the sealing plug 25 can be opened to discharge the liquid impurities, which is convenient and fast.

[0025] Further, a strip-shaped groove is formed in one side wall of the protective cover 6, and a sealing glass 26 is arranged in the strip-shaped groove. By arranging the sealing glass 26, the telescopic state of the telescopic pipe sleeve 4 can be observed through the sealing glass 26.

[0026] Further, a rubber film 27 is fixedly sleeved on the outer wall of the fixing ring 13, and one end of the rubber film 27 is fixedly connected to the sealing plate 11. By arranging the rubber film 27, when the counterweight liquid enters above the piston 12, the rubber film 27 can isolate the counterweight liquid from the thread on the sealing plate 11, thereby protecting the thread.

[0027] Further, a support limiting block 28 is fixedly sleeved on the outer wall of the support column 16. By arranging the support limiting block 28, after the support plate 5 moves down to a certain position, the support limiting block 28 can support the support plate 5.

[0028] Before use, install different numbers of counterweight blocks 9 according to the pressure of the pipeline system, and inject counterweight liquid into the second box body 10. When in use, connect the air inlet connecting pipe 1 to the air inlet pipe and the exhaust connecting pipe 2 to the exhaust pipe. At this time, the pressure in the pipeline will press up the bellows 401, and then rotate the screw rod 14. The rotating screw rod 14 drives the piston 12 to move. The moving piston 12 can press the counterweight liquid in the second box body 10 into the first box body 8, thereby increasing the weight above the support plate 5, making the counterweight above the support plate 5 balance with the pressure of the pipeline system, and then making the bellows 401 stop expanding; In this way, when the pressure in the pipeline system is too low, the counterweight above the support plate 5 will press the bellows 401, thereby causing the bellows 401 to contract. When the bellows 401 contracts, the bellows 401 will squeeze the gas in the bellows 401 into the pipeline system to increase the pressure of the pipeline system; when the pressure in the pipeline system is too high, the increased pressure will press up the support plate 5, causing the bellows 401 to elongate. At this time, a part of the gas in the pipeline system can enter the bellows 401 to reduce the pressure of the pipeline system, thereby stabilizing the pressure of the pipeline system; In this way, by the way of stabilizing the pressure through the cooperation of the counterweight and the bellows 401, without the need to cooperate with a compressor. When the pressure in the pipeline system is high, the bellows 401 can be made larger by the pressure, and a part of the gas enters the bellows 401 to stabilize the air pressure. When the pressure in the pipeline system is low, the counterweight can press the gas in the bellows 401 into the pipeline system to stabilize the pipeline system. This not only has a simple and reliable structure, but also the space in the bellows 401 can be changed, so that the device can accommodate more gas and does not need to make the tank very large, thus making the device very practical.

[0029] When the bellows 401 leaks, the leaked gas will enter the protective cover 6. When the detector 20 detects the leaked gas, the detector 20 can control the solenoid valve 18 to close through the controller 21, thereby making the protective cover 6 form a sealed space so that the gas will not leak out, thus making the device highly safe.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
