Description

Technical Field

[0001] This utility model relates to the field of gas filling technology, and in particular to gas filling pipeline components. Background Technology

[0002] Gas filling pipeline assemblies refer to pipeline systems and their auxiliary equipment used to safely and efficiently fill gases (such as industrial gases, liquefied petroleum gas, natural gas, medical oxygen, etc.) into gas cylinders, tanks or other containers. These assemblies typically need to have characteristics such as high pressure resistance, corrosion resistance and good sealing performance to ensure the safety and reliability of the filling process.

[0003] In gas filling operations, due to the lack of effective mechanical reinforcement measures at the connection between pipelines and storage containers, the system is prone to equipment displacement or interface loosening under dynamic filling conditions due to pressure fluctuations or external interference. This lack of mechanical stability may lead to risks such as gas leakage and pipeline stress concentration, reducing the practicality of the equipment. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a gas filling pipeline assembly that can reduce the risks of gas leakage and pipeline stress concentration.

[0005] According to an embodiment of the present utility model, a gas filling pipeline assembly includes a conveying pipeline, a one-way valve fixedly connected to the bottom end of the conveying pipeline, a connecting pipe fixedly connected to the bottom end of the one-way valve, a shut-off valve fixedly connected to the bottom end of the connecting pipe, a support pipe fixedly connected to the bottom end of the shut-off valve, a sealing cap fixedly connected to the bottom end of the support pipe, a positioning mechanism provided on the outside of the sealing cap, and a limit mechanism provided on one side of the positioning mechanism. The positioning mechanism includes a fixed arm, which is fixedly connected to the outer wall of the sealing cover. A fixed groove is fixedly connected to the inner side of the fixed arm. A long screw is rotatably connected to the inner wall of the fixed groove. A drive assembly is provided on the outer wall of the long screw. A threaded block is threadedly connected to the outer wall of the long screw. A right-angle plate is fixedly connected to one side of the threaded block. A positioning block is fixedly connected to the inner side of the right-angle plate. A drive shaft is provided inside the drive assembly. A handwheel is fixedly connected to the outer wall of the drive shaft.

[0006] It has at least the following beneficial effects: The positioning mechanism allows the threaded block to move via a right-angle plate, enabling it to clamp and position the storage container. This provides stable reinforcement for the connection between the sealing cap and the storage container, reducing the likelihood of equipment displacement or interface loosening due to pressure fluctuations or external interference during dynamic filling. It also lowers the risks of gas leaks and pipeline stress concentration, enhancing the device's practicality. The limiting mechanism allows for the rotation of a torsion sleeve, which in turn rotates a short screw. This allows the short screw to depress the round block back into the fixing groove, enabling further reinforcement work by cranking the handwheel, further enhancing the device's usability.

[0007] According to some embodiments of this utility model, rotating holes are provided on the front of the right-angle plate and inside the fixed arm, and the drive shaft is rotatably connected to the inner wall of the rotating hole.

[0008] According to some embodiments of the present invention, the drive assembly includes a driving bevel gear and a driven bevel gear, the drive shaft is fixedly connected to the inner ring of the driven bevel gear, the long screw is fixedly connected to the inner ring of the driving bevel gear, and the driving bevel gear and the driven bevel gear mesh with each other.

[0009] According to some embodiments of this utility model, the threads on the outer walls of the two ends of the long screw are in opposite directions, and the threaded blocks are slidably connected to the inner wall of the fixed groove.

[0010] According to some embodiments of the present invention, the limiting mechanism includes a circular block, which is disposed on one side of the fixing groove. A short screw is fixedly connected to the side of the circular block away from the fixing groove, and a torsion sleeve is fixedly connected to the end of the short screw away from the circular block.

[0011] According to some embodiments of this utility model, the side of the round block away from the short screw is provided with anti-slip texture, and the side of the round block away from the short screw is in close contact with the side of the fixing groove.

[0012] According to some embodiments of this utility model, a short screw passes through the handwheel, and a threaded hole is provided inside the handwheel, with the short screw threadedly connected to the inner wall of the threaded hole.

[0017] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0018] Reference Figures 1 to 6This utility model discloses a gas filling pipeline assembly, including a conveying pipeline 100, a one-way valve 400 fixedly connected to the bottom end of the conveying pipeline 100, a connecting pipe 500 fixedly connected to the bottom end of the one-way valve 400, a shut-off valve 600 fixedly connected to the bottom end of the connecting pipe 500, a support pipe 700 fixedly connected to the bottom end of the shut-off valve 600, a sealing cap 800 fixedly connected to the bottom end of the support pipe 700, a positioning mechanism 200 provided on the outside of the sealing cap 800, and a limit mechanism 300 provided on one side of the positioning mechanism 200; The positioning mechanism 200 includes a fixed arm 210, which is fixedly connected to the outer wall of the sealing cover 800. A fixed groove 211 is fixedly connected to the inner side of the fixed arm 210. A long screw 220 is rotatably connected to the inner wall of the fixed groove 211. A drive assembly 244 is provided on the outer wall of the long screw 220. A threaded block 230 is threadedly connected to the outer wall of the long screw 220. A right-angle plate 233 is fixedly connected to one side of the threaded block 230. A positioning block 240 is fixedly connected to the inner side of the right-angle plate 233. A drive shaft 250 is provided inside the drive assembly 244. A handwheel 222 is fixedly connected to the outer wall of the drive shaft 250.

[0019] In some embodiments, the right-angle plate 233 and the fixed arm 210 are both provided with rotating holes, and the drive shaft 250 is rotatably connected to the inner wall of the rotating hole to provide stable support for the drive shaft 250.

[0020] In some embodiments, the drive assembly 244 includes a driving bevel gear and a driven bevel gear, a drive shaft 250 is fixedly connected to the inner ring of the driven bevel gear, a long screw 220 is fixedly connected to the inner ring of the driving bevel gear, and the driving bevel gear and the driven bevel gear mesh with each other, thereby achieving the purpose of stable transmission.

[0021] In some embodiments, the threads on the outer walls of the two ends of the long screw 220 are in opposite directions, and the threaded block 230 is slidably connected to the inner wall of the fixed groove 211, so that the rotational motion of the long screw 220 is converted into the linear motion of the threaded block 230.

[0022] Reference Figures 1 to 6 In some embodiments, the limiting mechanism 300 includes a circular block 311, which is disposed on one side of the fixing groove 211. A short screw 310 is fixedly connected to the side of the circular block 311 away from the fixing groove 211. A torsion sleeve 320 is fixedly connected to the end of the short screw 310 away from the circular block 311 to ensure the stability of the adjustment.

[0023] In some embodiments, the side of the round block 311 away from the short screw 310 is provided with anti-slip texture, and the side of the round block 311 away from the short screw 310 is in close contact with the side of the fixing groove 211, thereby ensuring the stability of the handwheel 222 being pressed and limited.

[0024] In some embodiments, the short screw 310 passes through the handwheel 222, and the handwheel 222 has a threaded hole inside. The short screw 310 is threaded to the inner wall of the threaded hole, so that the short screw 310 can drive the round block 311 to press and limit the fixed groove 211.

[0025] Understandably, the gas can be transported through the conveying pipe 100, and the one-way valve 400 can reduce gas backflow. The gas is transported sequentially through the one-way valve 400 and the connecting pipe 500. The gas can be transported by switching the shut-off valve 600. Before opening the shut-off valve 600, the sealing cap 800 can be inserted into the top of the storage container through the support pipe 700. Then, the torsion sleeve 320 can be rotated, which can drive the short screw 310 to rotate, so that the short screw 310 can drive the round block 311 to stop pressing against the fixed groove 211. At this time, the handwheel 222 can be turned to rotate, which facilitates the further reinforcement work and enhances the practicality of the device.

[0026] It should be noted that after the handwheel 222 is released from its limit, the handwheel 222 can be cranked to rotate the drive shaft 250. The drive shaft 250, through the drive assembly 244, drives the long screw 220 to rotate. Since the long screw 220 and the threaded block 230 are threadedly connected, and the threaded block 230 can slide and limit itself on the inner wall of the fixed groove 211, the rotational motion of the long screw 220 is converted into the linear motion of the threaded block 230. The threaded block 230 can move the positioning block 240 through the right-angle plate 233, so that the positioning block 240 can clamp and position the storage container, providing a stable and reinforced guarantee for the connection between the sealing cap 800 and the storage container. This reduces the possibility of equipment displacement or interface loosening due to pressure fluctuations or external interference under dynamic filling conditions. At the same time, it can reduce the risk of gas leakage, pipeline stress concentration, etc., and enhance the practicality of the device.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
