Description

Technical Field

[0001] The utility model relates to the field of elbow pipes, in particular to an elbow connecting pipe for gas production. Background Art

[0002] In the pipeline system, elbows are pipe fittings that change the direction of the pipeline. According to the angle, there are three most commonly used elbows: 45°, 90° and 180°. In addition, according to the needs of the project, there are also other non-normal angle elbows such as 60°. At present, in the process of natural gas extraction, in order to transport natural gas to a designated location, a large number of elbows are used to connect pipes to change the direction of the pipeline.

[0003] However, traditional elbow connecting pipe devices for gas production still face some problems during use: First, the connection points between the two ends of the elbow connecting pipe and the natural gas transmission pipeline are usually suspended directly above the ground. Due to the lack of good ground support components, the connection points are prone to extrusion and deformation, which may cause gas leakage. At the same time, due to factors such as aging of pipeline components, internal corrosion or improper maintenance, the probability of natural gas leakage at the end connection of the elbow connecting pipe will gradually increase, but there is currently a lack of continuous monitoring and alarm functions for gas leakage of the elbow connecting pipe.

[0004] Therefore, it is necessary to provide a new elbow connecting pipe for gas production to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a gas extraction elbow connecting pipe which can stably support the connection between the elbow connecting pipe and the conveying pipe and has good gas leakage continuous monitoring and alarm functions.

[0006] In order to solve the above technical problems, the utility model provides an elbow connecting pipe for gas production, comprising: an elbow pipe, wherein conveying pipes are arranged at both ends of the elbow pipe, a right-angle base is arranged at the lower side of the elbow pipe, and the bottoms of both ends of the right-angle base are fixedly connected with fixing rods symmetrically on the left and right, the fixing rods are arranged obliquely, and the bottom of the fixing rods is rotatably connected with a first threaded sleeve, an oblique threaded rod is arranged inside the fixing rod, and the oblique threaded rod is threadedly connected to the first threaded sleeve, and both ends of the right-angle base are fixedly connected with fixing brackets, and a transverse threaded rod is rotatably connected to the surface of the right-angle base located on the lower side of the fixing bracket, and the surface of the transverse threaded rod is threadedly connected with a second threaded sleeve, and the top of the second threaded sleeve is fixed A movable bracket is fixedly connected, both ends of the elbow pipe are fixedly connected with a first flange, one end of the two delivery pipes close to the elbow pipe is fixedly connected with a second flange, a lower seal is arranged at the lower side of the first flange and the second flange, an upper seal is arranged on the upper side of the lower seal, a connecting pipe is connected between the two upper seals, a differential pressure gauge is installed on the surface of the connecting pipe, a side panel is welded to one side wall surface of the right-angle base, a solar cell panel is installed on the top of the side panel, a battery pack is connected to the bottom surface of the side panel by bolts, the battery pack is electrically connected to the solar cell panel, and warning lights are installed on the surface of the right-angle base located on both sides of the side panel through connecting blocks.

[0007] As a further solution of the utility model, fixing plates are welded on the surfaces of the upper seal and the lower seal, the two fixing plates distributed up and down are connected by bolts, and the first flange and the second flange on the adjacent side are fixed by bolts.

[0008] Through the above technical solution, the elbow pipe is connected to the conveying pipe through the first flange and the second flange, which can ensure good sealing performance of the structure. The upper seal and the lower seal are used to detect whether there is leakage at the internal elbow pipe connection, so they need to be sealed and fixed.

[0009] As a further solution of the utility model, a control module is installed on the bottom surface of the right-angle base, and the differential pressure gauge, warning light and battery pack are all electrically connected to the control module.

[0010] Through the above technical solution, the probability of natural gas leakage at the elbow pipe end connection will gradually increase due to factors such as aging of pipeline components, internal corrosion or improper maintenance. Therefore, when gas leakage occurs at the structural connection, natural gas will enter the cavity between the upper seal and the lower seal, and finally enter the connecting pipe. The differential pressure gauge set on the connecting pipe will feel the internal pressure change. When the internal pressure is greater than a set value, the two sets of warning lights will be activated through the control module to light up, so that patrol workers or operators in the monitoring room can discover and deal with it in time, and the control modules, warning lights and other electrical appliances in the structure can obtain electricity through the cooperation of solar panels and battery packs, thereby reducing the cost of use.

[0011] As a further solution of the utility model, the fixed bracket and the movable bracket are both semi-circular, and the surfaces of the fixed bracket and the movable bracket are both bonded with support pads.

[0012] Through the above technical solution, the connection points between the two ends of the elbow connecting pipe and the natural gas transmission pipeline are usually suspended directly above the ground. Due to the lack of good ground support components there, the connection is prone to extrusion and deformation, which may cause gas leakage. In the device, a fixed bracket is arranged on the upper side of the right-angle base to support the two ends of the elbow pipe, and a movable bracket whose position can be adjusted by a horizontal threaded rod is provided to support the transmission pipe connected to the elbow pipe. Shock-absorbing support pads are arranged on the surface of the fixed bracket and the movable bracket to prevent the structure from shaking due to its own gravity or the excessive internal gas flow rate and affecting the sealing of the connection. In addition, the toe on the right-angle base can be adjusted in height through the cooperation of the first threaded sleeve and the oblique threaded rod to adapt to various uneven ground.

[0013] As a further solution of the utility model, a limit rod is fixedly connected to the surface of the right-angle base located on one side of the transverse threaded rod, and the second threaded sleeve is slidably connected to the limit rod through a connecting block.

[0014] Through the above technical solution, the limiting rod and the second threaded sleeve are slidably connected, so that when the user rotates the transverse threaded rod, the limiting rod restricts the second threaded sleeve from only driving the movable bracket to move horizontally.

[0015] As a further solution of the utility model, a toe is installed at the end of the oblique threaded rod, a key slot is opened on the surface of the oblique threaded rod, a limiting block is welded inside the fixing rod, and the limiting block is slidably connected to the key slot.

[0016] Through the above technical solution, constrained by the sliding connection between the keyway and the limit block, when the user rotates the second threaded sleeve, the threaded rod can only be extended and retracted along the axis, thereby driving the toes to contact the ground.

[0017] As a further solution of the utility model, a plurality of evenly distributed anti-slip racks are provided on the surface of the first threaded sleeve, and a rotating handle is fixedly connected to the end of the transverse threaded rod.

[0018] Through the above technical solution, by setting the anti-slip rack, workers can rotate the first threaded sleeve more easily and labor-savingly, and by turning the rotating handle, the movable bracket on the horizontal threaded rod can be driven to adjust its position to support the conveying pipe.

[0019] Compared with the related art, the elbow connecting pipe for gas extraction provided by the utility model has the following beneficial effects:

[0020] 1. In the present invention, due to factors such as aging of pipeline components, internal corrosion or improper maintenance, the probability of natural gas leakage at the elbow pipe end connection will gradually increase. Therefore, when gas leakage occurs at the structural connection, natural gas will enter the cavity between the upper seal and the lower seal, and finally enter the connecting pipe. The differential pressure gauge set on the connecting pipe will feel the internal pressure change. When the internal pressure is greater than a set value, the control module will start two sets of warning lights to light up, so that the inspection workers or operators in the monitoring room can discover and deal with it in time, and the control module, warning lights and other electrical appliances in the structure can obtain electricity through the cooperation of solar panels and battery packs, thereby reducing the use cost;

[0021] 2. In the utility model, the connection points between the two ends of the elbow connecting pipe and the natural gas transmission pipeline are usually directly suspended above the ground. Due to the lack of good ground support components there, the connection points are prone to extrusion and deformation, which may cause gas leakage.

[0031] like Figure 1 As shown, fixing plates 17 are welded on the surfaces of the upper seal 3 and the lower seal 4. The two fixing plates 17 distributed up and down are connected by bolts, and the first flange 15 and the second flange 16 on the adjacent side are fixed by bolts.

[0032] The elbow pipe 1 is connected to the delivery pipe 2 through the first flange 15 and the second flange 16 to ensure good sealing performance of the structure, and the upper seal 3 and the lower seal 4 are used to detect whether there is leakage at the connection of the internal elbow pipe 1, so they need to be sealed and fixed.

[0033] like Figure 1 As shown, a control module 10 is installed on the bottom surface of the right-angle base 13 , and the differential pressure gauge 6 , the warning light 7 and the battery pack 9 are all electrically connected to the control module 10 .

[0034] Due to factors such as aging of pipeline components, internal corrosion or improper maintenance, the probability of natural gas leakage at the end connection of the elbow pipe 1 will gradually increase. Therefore, when gas leakage occurs at the structural connection, natural gas will enter the cavity between the upper seal 3 and the lower seal 4, and finally enter the connecting pipe 5. The differential pressure gauge 6 arranged on the connecting pipe 5 will feel the internal pressure change. When the internal pressure is greater than a set value, the two sets of warning lights 7 will be activated through the control module 10 to light up, so that the patrol workers or the operators in the monitoring room can discover and deal with it in time, and the control module 10, warning light 7 and other electrical appliances in the structure can obtain electricity through the cooperation of the solar panel 8 and the battery pack 9, thereby reducing the use cost.

[0035] like Figure 1 As shown, the fixed bracket 18 and the movable bracket 19 are both semi-circular, and the surfaces of the fixed bracket 18 and the movable bracket 19 are both bonded with a support pad 20 .

[0036] The connection points between the two ends of the elbow connecting pipe and the natural gas transmission pipe 2 are usually suspended directly above the ground. Due to the lack of good ground support components there, the connection is prone to extrusion and deformation, which may cause gas leakage. In this device, a fixed bracket 18 is arranged on the upper side of the right-angle base 13 to support the two ends of the elbow pipe 1, and is equipped with a movable bracket 19 whose position can be adjusted by a horizontal threaded rod 12 to support the transmission pipe 2 connected to the elbow pipe 1. Shock-absorbing support pads 20 are arranged on the surfaces of the fixed bracket 18 and the movable bracket 19 to prevent the structure from shaking due to its own gravity or the excessive internal gas flow rate and affecting the sealing of the connection. In addition, the toe 23 on the right-angle base 13 can be adjusted in height through the cooperation of the first threaded sleeve 14 and the oblique threaded rod 24 to adapt to various uneven ground.

[0037] like Figure 1 As shown, a limiting rod 22 is fixedly connected to the surface of the right-angle base 13 located on one side of the transverse threaded rod 12, and the second threaded sleeve 21 is slidably connected to the limiting rod 22 through a connecting block.

[0038] The limiting rod 22 is slidably connected to the second threaded sleeve 21 , so that when the user rotates the transverse threaded rod 12 , the limiting rod 22 constrains the second threaded sleeve 21 and can only drive the movable bracket 19 to move horizontally.

[0039] like Figure 1 As shown, a toe 23 is installed at the end of the oblique threaded rod 24, a key groove 25 is opened on the surface of the oblique threaded rod 24, and a limiting block is welded inside the fixing rod 11, and the limiting block is slidably connected with the key groove 25.

[0040] Constrained by the sliding connection between the key slot 25 and the limit block, when the user rotates the second threaded sleeve 21 , the threaded rod can only be extended and retracted along the axis, thereby driving the toe 23 to contact the ground.

[0041] like Figure 1 As shown, a plurality of evenly distributed anti-slip racks are provided on the surface of the first threaded sleeve 14, and a rotating handle is fixedly connected to the end of the transverse threaded rod 12.

[0042] The provision of the anti-slip rack makes it easier and less laborious for workers to rotate the first threaded sleeve 14 , and by turning the rotating handle, the position of the movable bracket 19 on the transverse threaded rod 12 can be adjusted to support the conveying pipe 2 .

[0043] The working principle of the elbow connecting pipe for gas extraction provided by the utility model is as follows:

[0044] Step 1: Due to factors such as aging of pipeline components, internal corrosion or improper maintenance, the probability of natural gas leakage at the end connection of the elbow pipe 1 will gradually increase. Therefore, when gas leakage occurs at the structural connection, natural gas will enter the cavity between the upper seal 3 and the lower seal 4, and finally enter the connecting pipe 5. The differential pressure gauge 6 set on the connecting pipe 5 will feel the internal pressure change. When the internal pressure is greater than a set value, the two sets of warning lights 7 will be activated through the control module 10 to light up, so that the inspection workers or the operators in the monitoring room can discover and deal with it in time, and the control module 10, warning light 7 and other electrical appliances in the structure can obtain electricity through the cooperation of the solar panel 8 and the battery pack 9, thereby reducing the use cost;

[0045] Step 2: The connection points between the two ends of the elbow connecting pipe and the natural gas transmission pipe 2 are usually suspended directly above the ground. Due to the lack of good ground support components there, the connection points are prone to extrusion and deformation, which may cause gas leakage. In this device, a fixed bracket 18 is arranged on the upper side of the right-angle base 13 to support the two ends of the elbow pipe 1, and a movable bracket 19 whose position can be adjusted by a horizontal threaded rod 12 is provided to support the transmission pipe 2 connected to the elbow pipe 1. Shock-absorbing support pads 20 are arranged on the surfaces of the fixed bracket 18 and the movable bracket 19 to prevent the structure from shaking due to its own gravity or the excessive internal gas flow rate and affecting the sealing of the connection. In addition, the toe 23 on the right-angle base 13 can be adjusted in height through the cooperation of the first threaded sleeve 14 and the oblique threaded rod 24 to adapt to various uneven ground.
