Description
Technical Field
[0001] The utility model relates to the technical field of gas pipeline connection, in particular to a gas pipeline reinforcement connection device. Background Art
[0002] Gas pipeline refers to the pipeline that transports natural gas (including associated gas produced by oil fields) from the mining site or processing plant to the urban gas distribution center or industrial enterprise users. It is also called gas transmission pipeline. Gas is a clean fuel with high calorific value, easy to transport and store, and abundant in resources. The vigorous development of the gas industry has made great contributions to the creation of green cities, the convenience of people's lives and the improvement of corporate production efficiency.
[0003] Generally, gas pipe joints are used to seal and connect two gas pipes. However, in the actual connection process of two gas pipes, the pipe joints are often misaligned due to improper installation or excessive pressure, resulting in gas leakage during the pipeline gas transportation process, which may cause major safety accidents and pose a huge safety hazard. Utility Model Content
[0004] The utility model aims to provide a gas pipeline reinforcement connection device to solve the leakage problem caused by pipeline misalignment and improve the safety of the gas pipeline transportation process.
[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions:
[0006] A gas pipeline reinforcement connection device includes a connection device for connecting two gas pipelines, the connection device includes a hose and pipe joints respectively arranged at both ends of the hose, the two gas pipelines are respectively sleeved on the outside of the pipe joints, the pipe joints are threaded with fixing blocks, the gas pipeline is clamped between the pipe joints and the fixing blocks, the pipe joints are provided with a first sealing ring in contact with the gas pipeline, and the fixing blocks are provided with an inclined surface in contact with the gas pipeline.
[0007] Furthermore, a plurality of elastic blocks spreading outward are provided at the end of the pipe joint, the side surfaces of the elastic blocks are in contact with the gas pipeline, and the gas pipeline is clamped between the inclined surface and the elastic blocks.
[0008] Furthermore, a second sealing ring is provided between the fixing block and the gas pipeline.
[0009] Furthermore, a sleeve is sleeved on the outer sides of the two fixing blocks, and two ends of the sleeve are detachably connected to the two fixing blocks respectively, and a leak-proof chamber is formed among the sleeve, the fixing blocks, the pipe joint and the hose.
[0010] Furthermore, clamps are provided at both ends of the sleeve, and a third sealing ring is provided between the sleeve and the fixing block.
[0011] Furthermore, the sleeve is made of a soft material and is provided with a pressure gauge.
[0012] Furthermore, both ends of the hose are provided with first flanges respectively, and the end of the pipe joint is provided with a second flange used in conjunction with the first flanges.
[0013] Furthermore, the second flange is provided with a groove, the first flange is provided with a protrusion that is snap-fitted with the groove, and the second flange is provided with a fourth sealing ring that contacts the protrusion.
[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] 1. The fixing block is sleeved on the outside of the pipe joint. Since both the gas pipeline and the pipe joint have a certain elasticity, the two pipe joints are respectively inserted into the gas pipeline by reducing the outer diameter of the pipe joint and increasing the outer diameter of the gas pipeline, and the gas pipeline is placed between the fixing block and the pipe joint. Then the hose is placed between the two pipe joints, and the position of the pipe joint is adjusted so that the ends of the two pipe joints are respectively sealed and connected with the two ends of the hose, thereby realizing the connection between the two gas pipelines; in addition, the slight bending deformation of the hose itself can compensate for the misalignment of the gas pipeline caused by improper installation or excessive pressure, avoid gas leakage between the two, and improve the safety of the gas pipeline transportation process;
[0016] 2. Rotate the fixing block on the pipe joint. Since the fixing block is threadedly connected to the pipe joint, it moves to both sides on the pipe joint and further contacts the gas pipeline through the inclined surface, causing it to be squeezed and deformed, and contacts the first sealing ring on the pipe joint to achieve sealing between the pipe joint and the gas pipeline, thereby avoiding leakage of the gas pipeline between the pipe joint and the gas pipeline and improving the safety of the gas pipeline transportation process.

[0025] A fixing block 5 is threadedly connected to the pipe joint 4, and the gas pipeline 1 is clamped between the pipe joint 4 and the fixing block 5. The fixing block 5 and the pipe joint 4 exert a force on the gas pipeline 1, which further prevents the pipe joint 4 from falling off the gas pipeline 1, thereby improving the safety of the gas pipeline 1 during transportation. The pipe joint 4 is provided with a first sealing ring 6 in contact with the gas pipeline 1, and the fixing block 5 is provided with an inclined surface 7 in contact with the gas pipeline 1.

Since the elastic block 8 spreads outward, it is convenient to compress the outer diameter of the elastic block 8, so that it can better enter the gas pipeline 1. At the same time, the elastic force applied by the elastic block 8 rebounds, and the friction between the elastic block 8 and the gas pipeline 1 is further increased, thereby preventing the pipe joint 4 from falling off the gas pipeline 1, and improving the safety of the gas pipeline 1 during transportation; when the elastic block 8 enters the interior of the gas pipeline 1, the end of the elastic block 8 will support the lower section of the gas pipeline 1, so that the inner diameter of this section of the gas pipeline 1 is larger than that of other sections of the gas pipeline 1, so that when the gas pipeline 1 is about to slide off the pipe joint 4, the gas pipeline 1 at the adjacent end contacts the elastic block 8, and the resistance generated will limit its further sliding off the pipe joint 4, thereby improving the safety of the gas pipeline 1 during transportation.
[0027] Preferably, Figure 2 and Figure 3 As shown, a second sealing ring 9 is provided between the fixing block 5 and the gas pipeline 1 to prevent gas leakage from between the fixing block 5 and the gas pipeline 1, thereby realizing a second layer of sealing of the connecting device 2, further preventing gas leakage, and improving the safety of the gas pipeline 1 transportation process.

A leak-proof chamber 11 is formed between the sleeve 10, the fixing blocks 5, the pipe joint 4, and the hose 3, so that the sleeve 10 wraps the leakage port of the connecting device 2. When the gas leaks from the connection between the pipe joint 4 and the gas pipe 1 or the hose 3 and the pipe joint 4, it first enters the leak-proof chamber 11 to avoid direct leakage of the gas and cause a greater safety hazard.

A third sealing ring 13 is provided between the sleeve 10 and the fixed block 5. By tightening the bolts on the clamp 12, the clamp 12 is locked and in contact with the sleeve 10, so that the sleeve 10 is in close contact with the third sealing ring 13 provided on the fixed block 5, thereby preventing direct leakage of gas and causing greater safety hazards.
[0030] Preferably, Figure 2As shown, the sleeve 10 is made of soft material to compensate for the misalignment of the gas pipeline 1 caused by improper installation or excessive pressure, ensure the stability of the connection of the gas pipeline 1, and improve the safety of the transportation process of the gas pipeline 1; the sleeve 10 is provided with a pressure gauge 14, and specific reference may be made to the YN60 model pressure gauge 14, which is used to detect whether there is a gas leak in the leak-proof chamber 11, so as to timely discover the gas leak and repair the leaking interface to avoid a greater safety hazard caused by a large amount of gas leakage, thereby improving the safety of the transportation process of the gas pipeline 1.
[0031] Preferably, Figure 2 and Figure 4 As shown, the two ends of the hose 3 are respectively provided with a first flange 15, and the end of the pipe joint 4 is provided with a second flange 16 used in conjunction with the first flange 15.

[0032] Preferably, Figure 2 and Figure 4 As shown, a groove 17 is provided on the second flange 16, and a protrusion 18 that is snap-fitted with the groove 17 is provided on the first flange 15, which plays a positioning role in the connection between the first flange 15 and the second flange 16, thereby improving the efficiency of connecting the first flange 15 and the second flange 16; a fourth sealing ring 19 that contacts the protrusion 18 is provided on the second flange 16 to prevent gas from leaking from between the hose 3 and the pipe joint 4, thereby realizing the first layer of sealing of the connecting device 2, thereby preventing gas leakage and improving the safety of the transportation process of the gas pipeline 1.
[0033] Example 1
[0034] The utility model provides a gas pipeline reinforcement connection device, such as Figure 1 , Figure 2 and Figure 3 As shown, the fixing block 5 is sleeved on the outside of the pipe joint 4. Since both the gas pipeline 1 and the pipe joint 4 have a certain elasticity, the two pipe joints 4 are respectively inserted into the gas pipeline 1 by reducing the outer diameter of the pipe joint 4 and increasing the outer diameter of the gas pipeline 1, and the gas pipeline 1 is located between the fixing block 5 and the pipe joint 4. Then, the hose 3 is placed between the two pipe joints 4, and the position of the pipe joint 4 is adjusted so that the ends of the two pipe joints 4 are respectively sealed and connected to the two ends of the hose 3, thereby realizing the connection between the two gas pipelines 1; in addition, the slight bending deformation of the hose 3 itself can compensate for the misalignment of the gas pipeline 1 caused by improper installation or excessive pressure, avoid gas leakage between the two, and improve the safety of the gas pipeline 1 transportation process;
[0035] Then, the fixing block 5 is rotated on the pipe joint 4. Since the fixing block 5 is threadedly connected to the pipe joint 4, it moves to both sides on the pipe joint 4, and further contacts the gas pipeline 1 through the inclined surface 7, so that it is squeezed and deformed, and contacts the first sealing ring 6 on the pipe joint 4, so as to achieve the sealing between the pipe joint 4 and the gas pipeline 1, avoid leakage of the gas pipeline 1 between the pipe joint 4 and the gas pipeline 1, and improve the safety of the gas pipeline 1 transportation process; at the same time, the force applied to the gas pipeline 1 by the fixing block 5 and the pipe joint 4 can further prevent the pipe joint 4 from falling off from the gas pipeline 1, and improve the safety of the gas pipeline 1 transportation process.
[0036] Example 2
[0037] Based on Example 1, Figure 2 and Figure 3 As shown, when the pipe joint 4 is connected to the gas pipeline 1, since the elastic block 8 spreads outward and has a certain elasticity, it is convenient to compress the outer diameter of the elastic block 8 so that it can better enter the gas pipeline 1. At the same time, the elastic force exerted by the elastic block 8 rebounds further increases the friction between the elastic block 8 and the gas pipeline 1, thereby preventing the pipe joint 4 from falling off the gas pipeline 1, thereby improving the safety of the gas pipeline 1 during transportation; when the elastic block 8 enters the interior of the gas pipeline 1, the end of the elastic block 8 will support the lower section of the gas pipeline 1, so that the inner diameter of this section of the gas pipeline 1 is larger than that of other sections of the gas pipeline 1, so that when the gas pipeline 1 is about to slide off the pipe joint 4, the gas pipeline 1 at the adjacent end contacts the elastic block 8, and the resistance generated will limit it from further sliding off the pipe joint 4, thereby improving the safety of the gas pipeline 1 during transportation;
[0038] Then, the fixing block 5 is rotated on the fixing joint to make it contact with the gas pipeline 1 until the gas pipeline 1 is clamped between the fixing block 5 and the pipeline joint 4. The second sealing ring 9 provided on the fixing block 5 contacts the gas pipeline 1 to prevent gas leakage from between the fixing block 5 and the gas pipeline 1, thereby realizing the second layer of sealing of the connecting device 2, further preventing gas leakage, and improving the safety of the transportation process of the gas pipeline 1.
[0039] Example 3
[0040] Based on Example 1, Figure 2As shown, the sleeve 10 is preferably placed on the outside of the gas pipeline 1. After the gas is connected and fixed, the two ends of the sleeve 10 are respectively moved to the outside of the two fixing blocks 5, and the bolts on the clamp 12 are tightened to lock the clamp 12 and contact the sleeve 10, so that the sleeve 10 is in close contact with the third sealing ring 13 provided on the fixing block 5, so that the sleeve 10 wraps the leakage port of the connecting device 2. When the gas leaks from the connection between the pipeline joint 4 and the gas pipeline 1 or the hose 3 and the pipeline joint 4, it first enters the leak-proof chamber 11 to avoid direct leakage of the gas and cause greater safety hazards. By arranging a pressure gauge 14 on the sleeve 10, it is possible to detect in real time whether there is a gas leak in the leak-proof chamber 11, so as to timely discover the gas leak and repair the leaking interface to avoid a large amount of gas leakage causing greater safety hazards, thereby improving the safety of the gas pipeline 1 transportation process.
[0041] Example 4
[0042] Based on Example 1, Figure 2 and Figure 4 As shown, after adjusting the position of the pipe joint 4, the protrusion 18 provided on the first flange 15 enters into the groove 17 provided on the second flange 16, which plays a positioning role in the connection between the first flange 15 and the second flange 16, thereby improving the efficiency of connecting the first flange 15 and the second flange 16; subsequently, the first flange 15 and the second flange 16 are connected by bolts and nuts to achieve a detachable connection between the hose 3 and the pipe joint 4, which is convenient for subsequent maintenance of the connection of the gas pipeline 1 and improves the efficiency of subsequent maintenance of the gas pipeline 1; at the same time, the protrusion 18 and the fourth sealing ring 19 provided on the second flange 16 are used to prevent gas from leaking between the hose 3 and the pipe joint 4, thereby achieving the first layer of sealing of the connecting device 2, thereby preventing gas leakage and improving the safety of the transportation process of the gas pipeline 1.
