Description

Technical Field

[0001] The utility model relates to the field of gas pipelines, and particularly to a gas pipeline construction plugging device. Background Technique

[0002] When a gas pipeline network leaks, it is necessary to promptly carry out emergency repair on the corresponding pipeline. Moreover, in order to reduce losses, during the emergency repair of gas pipelines, gas is usually carried while working.

[0003] At present, most pipeline plugging is carried out by using an airbag method. However, when the airbag is in an uninflated state, it is soft. Since the part with the leakage opening needs to be cut off during the repair of the gas pipeline, and there is still gas transmission and air pressure in the gas pipeline after cutting, it is affected by the air pressure when putting in the airbag and is not easy to put in. Summary of the Invention

[0004] Based on this, the purpose of the utility model is to provide a gas pipeline construction plugging device to solve the technical problem that there is still gas transmission and air pressure in the gas pipeline, which affects the insertion of the airbag due to air pressure and is not easy to insert.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A gas pipeline construction plugging device, including a plugging device body, and the plugging device body is composed of an airbag, an inflation tube, and a Tesla valve;

[0006] The outer surface of the airbag is provided with a thickening layer for increasing the service life;

[0007] The inflation tube horizontally penetrates along the central axis position of the airbag, and the inflation tube is fixedly bonded to the airbag by strong glue. An air nozzle for inflation is opened at the bottom end of the inflation tube. An air inlet channel is opened inside the inflation tube, and a number of air outlet nozzles are connected to the outside of the air inlet channel. A hollow tube is fixed at the end of the inflation tube;

[0008] The Tesla valve is threadedly connected to the hollow tube. An air inlet is provided at one end of the Tesla valve, and an air guide cover is threadedly connected to the Tesla valve through the air inlet. An air outlet is opened at the other end of the Tesla valve.

[0009] By adopting the above technical solution, the inflation tube horizontally penetrates along the central axis position of the airbag and is fixedly bonded by strong glue, ensuring a firm connection between the inflation tube and the airbag, not easy to fall off or leak air.

[0010] Furthermore, the hollow tube is made of metal material, and a number of through holes are opened on the outer surface of the hollow tube.

[0011] By adopting the above technical solution, the hollow tube made of metal material has excellent structural strength and durability, and can remain stable in a complex gas pipeline construction environment, and is not easily damaged or deformed.

[0012] Furthermore, the airbag is made of rubber material.

[0013] By adopting the above technical solution, the airbag made of rubber material has excellent elasticity and flexibility, can well adapt to gas pipelines of different shapes and sizes, ensures that the plugging device can closely fit the inner wall of the pipeline, and achieves a good plugging effect.

[0014] Furthermore, a cover plate is fixed at the front end of the air supply pipe, and a bell is connected to the top of the cover plate through a connecting rope.

[0015] By adopting the above technical solution, after the plugging device body completes the plugging, workers can monitor the plugging situation through the bell.

[0016] Furthermore, a handle is fixed at the middle position of the front end of the cover plate, and a rubber sleeve is installed on the outer surface of the handle.

[0017] By adopting the above technical solution, the staff can operate the plugging device more conveniently. The handle makes it more labor-saving to insert, rotate or move the plugging device, improving work efficiency.

[0018] Furthermore, the air guide cover is made of plastic material, and the air guide cover is detachably connected to the air inlet of the Tesla valve by threads.

[0019] By adopting the above technical solution, plastic materials usually have a relatively light weight and good durability, making the air guide cover easy to install and carry, and at the same time can maintain stable performance in a complex construction environment.

[0020] Furthermore, the diameter of the air guide cover is smaller than the maximum diameter of the airbag, and the diameter of the air guide cover is smaller than the diameter of the gas pipeline.

[0021] By adopting the above technical solution, after the air guide cover is inserted into the gas pipeline, it can cooperate with the Tesla valve to effectively block part of the gas and will not cause complete blockage. Therefore, at the initial stage of putting the airbag in, the pressure on the worker is small, which is convenient for putting the airbag in and inflating it for plugging.

[0022] In summary, the main beneficial effects of the present utility model are as follows:

[0023] The utility model supports the airbag by arranging an inflation pipe which horizontally penetrates through the center of the airbag, and installs a Tesla valve and a gas guide cover at the end. The gas guide cover can gather the gas, so that most of the gas enters the Tesla valve through the air inlet. Under the action of the Tesla valve, the gas is blocked, and its fluidity becomes slower, thereby reducing the air pressure at the airbag. Then, gas is filled into the airbag through the air nozzle. During the process of the airbag gradually expanding, the outer wall of the airbag gradually fits with the outer wall of the gas pipeline, thereby blocking the gas pipeline.

[0024] The utility model connects a bell to the top of the cover plate through a connecting rope. When plugging, the operator holds the handle and inserts the plugging device body into the gas pipeline, so that the cover plate is located at the cutting opening of the gas pipeline. After the plugging device body completes the plugging, the worker places the bell on the gas pipeline. If the air pressure in the gas pipeline is too high and squeezes the airbag to slide outwards, it will drive the cover plate to move outwards, and the bell will fall and produce a sound to remind the operator, which is beneficial for the operator to understand the situation of the plugging device at any time and facilitates the worker to handle.

Detailed Description of the Embodiment

[0030] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0031] The embodiments of the present utility model will be described below according to its overall structure. Embodiment 1

[0032] A gas pipeline construction plugging device, as Figures 1 - 4As shown in the figure, it includes a plugging device body 100, and the plugging device body 100 is composed of an airbag 1, an inflation tube 4, and a Tesla valve 5;

[0033] The outer surface of the airbag 1 is provided with a thickening layer 11 for increasing the service life;

[0034] The inflation tube 4 runs horizontally through the central axis position of the airbag 1. The inflation tube 4 is adhesively fixed to the airbag 1 with strong glue. An air nozzle 41 for inflation is opened at the bottom end of the inflation tube 4. An air inlet channel 42 is opened inside the inflation tube 4. A number of air outlet nozzles 43 are connected to the outside of the air inlet channel 42. A hollow tube 44 is fixed at the end of the inflation tube 4;

[0035] The Tesla valve 5 is threadedly connected to the hollow tube 44. An air inlet 51 is provided at one end of the Tesla valve 5. A gas guide cover 6 is threadedly connected to the Tesla valve 5 through the air inlet 51. An air outlet 52 is opened at the other end of the Tesla valve 5. The inflation tube 4 runs horizontally through the central axis position of the airbag 1 and is adhesively fixed with strong glue, ensuring a firm connection between the inflation tube and the airbag, not easily falling off or leaking air. The Tesla valve 5 gathers and blocks the gas through the gas guide cover 6, effectively reducing the air pressure at the airbag 1, making it easier for the airbag to be inflated and fit the inner wall of the pipeline, so as to achieve a good plugging effect. The outer surface of the airbag 1 is provided with a thickening layer 11, which can increase the wear resistance and tear resistance of the airbag and extend its service life.

[0036] Please refer to Figure 2 , the hollow tube 44 is made of metal material, and a number of through holes are opened on the outer surface of the hollow tube 44. The metal hollow tube 44 has excellent structural strength and durability, can remain stable in a complex gas pipeline construction environment, and is not easily damaged or deformed. The hollow tube 44 is completely connected to the gas pipeline. When part of the gas passes through the Tesla valve 5, it will re-enter the gas pipeline through the hollow tube 44 without causing loss.

[0037] Please refer to Figure 1 , the airbag 1 is made of rubber material. The rubber airbag 1 has excellent elasticity and flexibility, can well adapt to gas pipelines of different shapes and sizes, ensure that the plugging device can closely fit the inner wall of the pipeline, and achieve a good plugging effect. The rubber material has good sealing performance and can effectively prevent gas leakage. During the inflation process, the rubber airbag can quickly expand and closely fit the inner wall of the pipeline to form an effective sealing layer to ensure construction safety.

[0038] Please refer to Figure 3, a cover plate 2 is fixed to the front end of the gas charging pipe 4. A bell is connected to the top of the cover plate 2 by a connecting rope. After the plugging device body 100 completes the plugging, the worker can monitor the plugging situation through the bell which is not mentioned in the description but can be inferred from the context. If the air pressure in the gas pipeline is too high and causes the airbag to slide outwards, the bell will fall off and make a sound, reminding the staff to deal with it in time, thus ensuring the safety of the operation process. Embodiment 2

[0039] Please refer to Figure 3 , a handle 3 is fixed at the middle position of the front end of the cover plate 2. A rubber sleeve is installed on the outer surface of the handle 3. The staff can operate the plugging device more conveniently. The handle makes it more labor-saving to insert, rotate or move the plugging device, improving the work efficiency. The installation of the rubber sleeve provides a better holding feeling for the staff, reducing the operation errors caused by sliding or hand fatigue. At the same time, the rubber material can reduce the discomfort caused by friction and lower the risk of hand injury.

[0040] Please refer to Figure 4 , the air guide cover 6 is made of plastic. The air guide cover 6 is detachably connected to the air inlet 51 of the Tesla valve 5 by threads. Plastic materials usually have a relatively light weight and good durability, making the air guide cover 6 easy to install and carry. At the same time, it can maintain stable performance in complex construction environments. The plasticity and processability of plastic materials are good, and the air guide cover 6 with appropriate shape and size can be made according to actual needs. This helps to ensure the matching degree between the air guide cover 6, the gas pipeline and the Tesla valve 5, improving the plugging effect.

[0041] Please refer to Figure 4 , the diameter of the air guide cover 6 is smaller than the maximum diameter of the airbag 1, and the diameter of the air guide cover 6 is smaller than the diameter of the gas pipeline. After the air guide cover 6 is inserted into the gas pipeline, it can cooperate with the Tesla valve 5 to effectively block part of the gas, without causing complete plugging. Therefore, at the initial stage of putting the airbag in, the pressure on the worker is small, which is convenient for putting the airbag in and inflating it for plugging.

[0042] The implementation principle of this embodiment is as follows: First, check the integrity of the plugging device body to ensure that components such as the airbag, air charging pipe, Tesla valve, and air guide cover are not damaged. Prepare an air pump, and then assemble the plugging device body 100. Select a suitable air guide cover 6 and install it on the Tesla valve 5. Fix the Tesla valve 5 on the hollow pipe 44. After that, insert the plugging device body 100 into the gas pipeline. The air guide cover 6 can gather the gas, enabling most of the gas to enter the Tesla valve 5 through the air inlet 51. Under the action of the Tesla valve 5, the gas is blocked, its fluidity is slowed down, thereby reducing the air pressure at the airbag. Then, connect the connecting pipe of the inflation device to the air nozzle 41 of the plugging device, turn on the inflation device, and start inflating the airbag 1. During the inflation process, observe the inflation situation of the airbag 1 to ensure that the airbag 1 gradually expands and fits the inner wall of the pipeline. When the airbag 1 is fully inflated and closely fits the inner wall of the pipeline, turn off the inflation device to complete the plugging work. After the plugging device body 100 completes the plugging, the worker places the bell 21 on the gas pipeline. If the air pressure in the gas pipeline is too high and squeezes the airbag 1 to slide outwards, it will drive the cover plate 2 to move outwards, and the bell 21 will fall and produce a sound to remind the staff.
