Description
Technical Field
[0001] This utility model relates to the technical field of gas drainage equipment, specifically to a gas pipeline drainer. Background Technology
[0002] During the transportation and combustion of gas, condensate in gas pipelines can affect the normal operation of gas transportation and combustion equipment. If the condensate is not drained from the gas pipeline in a timely manner, it can lead to damage to the gas transportation equipment, malfunction of the gas combustion equipment, and even endanger personal safety. To ensure the safe operation of the pipeline network, it is essential to manually drain the condensate or install gas drainers in a timely manner. Gas drainers are crucial devices in gas distribution systems, collecting and draining condensate from the gas pipelines. To ensure the safe operation of gas pipelines, drainers should be installed at regular intervals to promptly drain the condensate.
[0003] When gas pipeline drainers are used in gas networks, their working principle is based on the water seal formed by the drain pipe of the gas pipeline being inserted into water. This water seal creates a pressure higher than the gas pressure within the network, preventing gas leakage while allowing liquid to drain normally. However, in actual use, because gas pressure is not constant, changes in production conditions can cause a sudden and significant increase in gas pressure. Under this pressure surge, the water seal of the gas drainer can be ruptured, leading to a large-scale gas leak along the drainer's overflow outlet, causing a serious safety accident. Summary of the Invention
[0004] To address the problem in existing gas pipeline drainers where the water seal is broken, causing significant gas leakage along the overflow outlet, this invention proposes a gas pipeline drainer. This drainer incorporates a buoyancy component in its leak-proof device to effectively seal the gas, thereby preventing large-scale gas leakage.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A gas pipeline drainer includes a drainer body, which comprises a cylinder and a partition plate. The partition plate divides the interior of the cylinder into a high-pressure chamber and a low-pressure chamber from left to right. The drainer also includes a leak-proof device, which includes a water outlet pipe connected to the cylinder via a connecting pipe. The water outlet pipe is divided into upper and lower parts, and a flange seat is provided at the connection between the upper and lower parts. A buoyancy assembly is provided on the flange seat. The buoyancy assembly includes a float located below the flange seat, with a connecting rod connected to the upper end of the float. A valve seat is provided through the flange seat, and the connecting rod is hinged to the valve seat. A water passage hole is also provided in the center of the valve seat, and a plug for sealing the water passage hole is provided at one end of the connecting rod. A hollow tube is provided at the bottom of the valve seat, and the plug is located inside the hollow tube. In the buoyancy assembly, the connecting rod forms a hinge structure with the valve seat through the bracket, and together with the float, plug, and hollow tube, they form a linkage system. When the water level changes, the system can react quickly. By having the float float up and down in the outlet pipe, it drives the plug to swing up or down to open and close the water passage.
[0006] Furthermore, a water inlet pipe is installed inside the high-pressure chamber, with one end extending out from the top of the cylinder and equipped with a water inlet valve. The water inlet pipe extends to the top of the cylinder and is equipped with a water inlet valve to achieve quick connection with the gas pipeline and isolation for maintenance.
[0007] Furthermore, the connecting rod is an L-shaped rod, which includes a long side and a short side; a bracket is provided on one side of the hollow tube on the valve seat, the long side of the connecting rod is hinged to the bottom of the bracket, and the float is fixedly connected to the short side end of the connecting rod.
[0008] Furthermore, a notch is provided on one side of the hollow tube, and the long side of the connecting rod passes through the notch and connects to the plug. The top of the plug is arc-shaped. The arc-shaped structure at the top of the plug matches the boss at the bottom of the valve seat, ensuring that the water passage is completely sealed, forming a good sealing effect.
[0009] Furthermore, the bottom of the hollow tube is provided with a boss that mates with the plug, and the water passage hole passes through the boss and the valve seat in sequence.
[0010] Furthermore, a pipe is provided on the partition, which penetrates the partition and is inserted into the lower part of the low-pressure chamber. By providing a pipe that penetrates the partition, condensate flows from the high-pressure chamber into the low-pressure chamber, and then is discharged through a connecting pipe, an outlet pipe, and an overflow port, ensuring a stable drainage process.
[0011] Furthermore, a drain valve is fixedly installed at the bottom left side of the cylinder.
[0012] Furthermore, the outlet pipe is equipped with an overflow port, and a drainage pipe is located below the overflow port. The top of the drainage pipe has a funnel-shaped drainage opening, and the lower end of the drainage pipe extends downwards. One side of the drainage pipe is fixedly connected to the outer wall of the outlet pipe via a bracket. The overflow port on the outlet pipe and the drainage pipe below it further improve drainage efficiency. The funnel-shaped drainage opening at the top of the drainage pipe can more effectively collect and drain condensate, preventing water accumulation.
[0013] The beneficial effects of this utility model through the above technical solution are as follows: The leak-proof device in this invention is equipped with a buoyancy component. The connecting rod forms a hinge structure with the valve seat through the bracket, and together with the float, plug, and hollow tube, forms a linkage system. When the water level changes, the system can react quickly. By having the float float up and down in the outlet pipe, it drives the plug to swing up or down to open and close the water passage. If the water seal of the drainer body is broken, gas carrying a large amount of water enters the outlet pipe through the connecting pipe. When the buoyancy of the water in the outlet pipe is greater than the weight of the float, the float moves upward due to the buoyancy, causing the connecting rod to swing, which drives the plug to swing downward, opening the water passage and discharging some water. When the water level drops and the buoyancy is insufficient to float the float, the float will move downward, causing the plug to move upward and close the water passage. Only a small amount of water flows out of the outlet pipe, effectively sealing the gas and preventing a large gas leak. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-5 As shown, this embodiment provides a gas pipeline drainer, including a drainer body, which includes a cylinder 1 and a partition 2. The partition 2 divides the interior of the cylinder 1 into a high-pressure chamber 3 and a low-pressure chamber 4 from left to right. It also includes a leak prevention device, which includes a water outlet pipe 5. The water outlet pipe 5 is connected to the cylinder 1 through a connecting pipe 6. The water outlet pipe 5 is divided into upper and lower parts. A flange seat 7 is provided at the connection between the upper and lower parts of the water outlet pipe 5. A buoyancy component is provided on the flange seat 7. The buoyancy assembly includes a float 8 located below the flange seat 7, with a connecting rod 9 connected to the upper end of the float 8. A valve seat 10 is provided through the flange seat 7, and the connecting rod 9 is hinged to the valve seat 10. A water passage hole 12 is also provided in the center of the valve seat 10, and a plug 13 for closing the water passage hole 12 is provided at one end of the connecting rod 9. A hollow tube 11 is provided at the bottom of the valve seat 10, and the plug 13 is located inside the hollow tube 11.
[0017] The leak-proof device in this utility model is equipped with a buoyancy component. The connecting rod 9 forms a hinge structure with the valve seat 10 through the bracket 16, and together with the float 8, plug 13, and hollow tube 11, it forms a linkage system. When the water level changes, the system can react quickly. By having the float 8 float up and down in the outlet pipe 5, it drives the plug 13 to swing up or down to open and close the water passage 12. If the water seal of the drainer body is broken, gas carrying a large amount of water will enter through the connecting pipe 6. When the buoyancy of the water in the outlet pipe 5 is greater than the weight of the float 8, the float 8 moves upward due to the buoyancy, causing the connecting rod 9 to swing downward, which drives the plug 13 to swing downward, opening the water passage 12 and discharging some water. When the water level drops and the buoyancy is insufficient to float the float 8, the float 8 will move downward, causing the plug 13 to move upward and seal the water passage 12. Only a small amount of water flows out of the outlet pipe 5, forming a good sealing effect on the gas, thereby preventing a large amount of gas leakage.
[0018] In this embodiment, a water inlet pipe 14 is provided inside the high-pressure chamber 3. One end of the water inlet pipe 14 extends out of the top of the cylinder 1 and is equipped with a water inlet valve 15. The water inlet pipe 14 extends to the top of the cylinder 1 and is equipped with a water inlet valve 15 to achieve quick connection and maintenance isolation with the gas pipeline.
[0019] Specifically, the connecting rod 9 is an L-shaped rod, including a long side and a short side; a bracket 16 is provided on one side of the hollow tube 11 on the valve seat 10, the long side of the connecting rod 9 is hinged to the bottom of the bracket 16, and the float 8 is fixedly connected to the short end of the connecting rod 9. The connecting rod 9 is an L-shaped rod, and forms a hinge structure with the valve seat 10 through the bracket 16. This design allows the connecting rod 9 to rotate flexibly.
[0020] Please refer to this again. Figure 3 and Figure 4 A notch 17 is provided on one side of the hollow tube 11. The long side of the connecting rod 9 passes through the notch 17 and connects to the plug 13. The top of the plug 13 is arc-shaped. The arc-shaped structure at the top of the plug 13 cooperates with the boss 18 at the bottom of the valve seat 10 to ensure that the water passage hole 12 is completely closed, forming a good sealing effect.
[0021] In addition, the bottom of the hollow tube 11 is provided with a boss 18 that cooperates with the plug 13, and the water passage 12 passes through the boss 18 and the valve seat 10 in sequence.
[0022] In this embodiment, a pipe 19 is provided on the partition 2, which penetrates the partition 2 and is inserted into the lower part of the low-pressure chamber 4. By providing the pipe 19 that penetrates the partition 2, condensate flows from the high-pressure chamber 3 into the low-pressure chamber 4, and then is discharged through the connecting pipe 6, the outlet pipe 5, and the overflow port 21, ensuring a stable drainage process.
[0023] It is worth mentioning that a drain valve 20 is fixedly installed at the bottom left side of the cylinder 1. The drain valve 20 at the bottom of the cylinder 1 facilitates the drainage of residual water during equipment cleaning or maintenance.
[0024] Please refer to this again. Figure 1 The water outlet pipe 5 is equipped with an overflow port 21, and a drainage pipe 22 is provided below the overflow port 21. The top of the drainage pipe 22 is provided with a funnel-shaped drainage port 23, and the lower end of the drainage pipe 22 extends downward. One side of the drainage pipe 22 is fixedly connected to the outer wall of the water outlet pipe 5 through a bracket 24. The design of the overflow port 21 on the water outlet pipe 5 and the drainage pipe 22 below it further improves the drainage efficiency. The funnel-shaped drainage port 23 at the top of the drainage pipe 22 can more effectively collect and discharge condensate, preventing water accumulation.
[0025] The working principle of this utility model is as follows: After installation, the gas pipeline is connected to the inlet pipe 14 of the gas pipeline drainer. When the condensate from the gas pipeline enters the high-pressure chamber 3 of the cylinder 1 through the inlet pipe 14, and then enters the low-pressure chamber 4 of the cylinder 1 through the pipe 19 on the partition 2, if the water seal of the drainer body is broken, the gas, carrying a large amount of water, enters the outlet pipe 5 through the connecting pipe 6. When the buoyancy of the water in the outlet pipe 5 is greater than the weight of the float 8, the float 8 moves upward due to the buoyancy, and the connecting rod 9 swings, driving the plug 13 to swing downward, so that the water passage hole 12 opens and discharges some water. When the water level drops and the buoyancy is insufficient to float the float 8, the float 8 will move downward, thereby causing the plug 13 to move upward and seal the water passage hole 12. Only a small amount of water flows out of the outlet pipe 5, forming a good sealing effect on the gas. The gas will be blocked inside the outlet pipe 5, thereby preventing a large amount of gas leakage and further preventing serious hazards.
[0026] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
