Description

Technical Field

[0001] This utility model relates to the field of natural gas venting technology, and in particular to a natural gas venting device. Background Technology

[0002] Natural gas is a mixture of hydrocarbon and non-hydrocarbon gases found in underground strata, typically referring to natural gas gases produced in oil fields, coalfields, and swampy areas. During the transportation, storage, and use of natural gas, if equipment damage occurs or the internal pressure of the pipeline becomes too high, the natural gas in the pipeline needs to be released to improve safety. Generally, the venting device consists of a venting pipe, valves, and pressure gauges. In use, the valve is opened, and the natural gas is released through the venting pipe.

[0003] Existing natural gas venting devices consist of a horizontal pipe and a vertical pipe. Since there is only one vertical pipe, natural gas is vented solely through it. When the vertical pipe becomes blocked or malfunctions, the venting process is affected, hindering rapid venting and posing a safety hazard. Furthermore, the vertical pipe requires a specialized support bracket for fixation, which is extremely inconvenient to install on the ground. Due to ground limitations, installation accuracy may be compromised, affecting the precise installation of the vertical pipe. Additionally, the upper part of the vertical pipe lacks a rainproof structure, allowing rainwater to enter and cause internal corrosion, compromising the pipe's integrity. Utility Model Content

[0004] The main objective of this invention is to provide a natural gas venting device that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A natural gas venting device includes a venting horizontal pipe, a pressure gauge and an on / off valve on the venting horizontal pipe, a three-way reversing valve installed at the end of the venting horizontal pipe, and a delivery pipe connected to the three-way reversing valve. The end of the delivery pipe is connected to a venting vertical pipe via an elbow, and a support structure connected to the venting vertical pipe is provided on the delivery pipe. A rainproof structure is installed at the upper end of the venting vertical pipe.

[0007] Preferably, the venting cross pipe and the conveying pipe are provided with support frames.

[0008] Preferably, the upper end of the venting vertical pipe is provided with an external thread, and the rainproof structure is fixed to the upper end of the venting vertical pipe by the external thread.

[0009] Preferably, the support structure includes a first connecting sleeve, a second connecting sleeve, a rotating inner rod, a rotating outer sleeve, and an adjusting bolt. The first connecting sleeve and the second connecting sleeve are respectively sleeved on the conveying pipe and the venting vertical pipe. The rotating inner rod is rotatably connected to the first connecting sleeve. The rotating outer sleeve is rotatably connected to the adjusting bolt, and the end of the rotating outer sleeve is sleeved on the rotating inner rod. The adjusting bolt is threadedly connected to the rotating outer sleeve, and the end of the adjusting bolt abuts against the rotating inner rod.

[0010] Preferably, the rainproof structure includes an installation joint, a threaded groove, a bearing, a support rod, a rotating rod, a limiting counterweight, a rain cover, and a drive blade. The installation joint is connected to the external thread at the upper end of the venting vertical pipe via the threaded groove. The bearing is installed on the installation joint. The support rod is fixedly connected to the rotating rod, and the rotating rod passes through the installation joint and the bearing. The limiting counterweight is installed at the lower end of the rotating rod. The rain cover and the drive blade are fixedly connected, and the rain cover is fixed to the top of the support rod.

[0011] Compared with the prior art, this utility model has the following beneficial effects: This natural gas venting device, through its three-way reversing valve, delivery pipe, and venting riser, allows for natural gas venting using the other venting riser when one riser becomes blocked, ensuring normal venting operations. Support structures are installed on the delivery pipe and venting riser, eliminating the need for ground support to guarantee the stability of the venting riser. The rotating inner rod and rotating outer sleeve are rotatably mounted on the first and second connecting sleeves, respectively, and are movably connected, allowing for angle adjustment according to actual conditions. This ensures stable support for the venting riser without affecting its precise installation. The rainproof structure effectively prevents rainwater from entering and corroding the venting riser. Through the included bearings, support rods, rotating rods, and drive blades, the drive blades rotate under the impact of rain and wind during rainy weather, rotating with the rainproof cover and applying centrifugal force to expel rainwater, further improving the rainproof effect.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-4 As shown, a natural gas venting device includes a venting horizontal pipe 1, a pressure gauge 2 and an on / off valve 3 mounted on the venting horizontal pipe 1, a three-way directional valve 4 installed at the end of the venting horizontal pipe 1, and a delivery pipe 5 connected to the three-way directional valve 4. The end of the delivery pipe 5 is connected to a venting vertical pipe 6 via an elbow 10, and a support structure 7 connected to the venting vertical pipe 6 is provided on the delivery pipe 5. A rainproof structure 8 is installed at the upper end of the venting vertical pipe 6. Support frames 9 are provided on the venting horizontal pipe 1 and the delivery pipe 5. An external thread 11 is provided at the upper end of the venting vertical pipe 6, and the rainproof structure 8 is fixed to the upper end of the venting vertical pipe 6 via the external thread 11.

[0019] When using the venting device, the venting horizontal pipe 1 and the conveying pipe 5 are stably set by the support frame 9. A venting vertical pipe 6 is installed at the end of the conveying pipe 5 via an elbow 10. The end of the venting horizontal pipe 1 is connected to the pipeline transporting natural gas. The pressure gauge 2 is used to monitor the gas pressure inside the pipeline. When the pressure is too high and natural gas needs to be vented, the on / off valve 3 is activated to carry out the venting operation. During the venting process, due to the action of the three-way reversing valve 4, one of the conveying pipes 5 is connected to the venting horizontal pipe 1, and the corresponding venting vertical pipe 6 vents the natural gas. If the venting vertical pipe 6 cannot vent normally, the three-way reversing valve 4 is used to reverse the direction, and the other conveying pipe 5 is connected to the venting horizontal pipe 1, and the venting vertical pipe 6 on the conveying pipe 5 vents the natural gas.

[0020] Throughout the entire operation of the device, the support structure 7 provides stable support for the discharge riser 6, while the rainproof structure 8 provides rain protection, preventing rainwater from entering the discharge riser 6 and causing erosion, thus ensuring the integrity of the device.

[0021] According to the above implementation scheme, the support structure 7 includes a first connecting sleeve 701, a second connecting sleeve 702, a rotating inner rod 703, a rotating outer sleeve 704, and an adjusting bolt 705. The first connecting sleeve 701 and the second connecting sleeve 702 are respectively sleeved on the conveying pipe 5 and the venting vertical pipe 6. The rotating inner rod 703 is rotatably connected to the first connecting sleeve 701. The rotating outer sleeve 704 is rotatably connected to the adjusting bolt 705, and the end of the rotating outer sleeve 704 is sleeved on the rotating inner rod 703. The adjusting bolt 705 is threadedly connected to the rotating outer sleeve 704, and the end of the adjusting bolt 705 abuts against the rotating inner rod 703.

[0022] When installing the venting riser 6, firstly, the first connecting sleeve 701 is attached to the conveying pipe 5, and the second connecting sleeve 702 is connected to the venting riser 6. After installing the support frame 9 on the conveying pipe 5, the venting riser 6 is installed using the elbow 10, so that the rotating outer sleeve 704 on the second connecting sleeve 702 is connected to the rotating inner rod 703 on the first connecting sleeve 701. The positions of the two connecting sleeves are adjusted, and the rotating outer sleeve 704 moves relative to the rotating inner rod 703 until it is adjusted to a suitable position. Finally, it is tightened and fixed using the adjusting bolt 705. During use, the rotating inner rod 703 and the rotating outer sleeve 704 provide a stable support effect, ensuring the stable use of the venting riser 6.

[0023] According to the above implementation scheme, the rainproof structure 8 includes a mounting joint 801, a threaded groove 802, a bearing 803, a support rod 804, a rotating rod 805, a limiting counterweight 806, a rainproof cover 807, and a drive blade 808. The mounting joint 801 is connected to the external thread 11 at the upper end of the venting vertical pipe 6 through the threaded groove 802. The bearing 803 is mounted on the mounting joint 801. The support rod 804 is fixedly connected to the rotating rod 805, and the rotating rod 805 passes through the mounting joint 801 and the bearing 803. The limiting counterweight 806 is mounted at the lower end of the rotating rod 805. The rainproof cover 807 is fixedly connected to the drive blade 808, and the rainproof cover 807 is fixed to the top of the support rod 804.

[0024] When assembling the rainproof structure 8, a bearing 803 is installed on the mounting joint 801. The rotating rod 805 at the lower end of the support rod 804 passes through the mounting joint 801 and the bearing 803. A limiting counterweight 806 is installed at the lower end of the rotating rod 805, thereby completing the assembly of the entire rainproof structure 8. When installing the rainproof structure 8, the mounting joint 801 is set to the external thread 11 at the upper end of the venting riser 6 using the threaded groove 802. The rotating rod 805 and the limiting counterweight 806 enter the venting riser 6, and the rainproof cover 807 is located above the venting riser 6.

[0025] During use, the rain cover 807 serves to prevent rain. When rainwater falls on the drive blade 808, the inclined drive blade 808 is subjected to force, and part of the force generates a rotational driving force. This causes the drive blade 808 to rotate along with the rain cover 807, support rod 804, and rotating rod 805 through the bearing 803. The rotation of the rain cover 807 generates centrifugal force, which can throw out the rainwater, thereby forming a rain curtain to block nearby rainwater and further improve the rainproof effect.

[0026] It should be noted that, through the three-way reversing valve 4, the delivery pipe 5, and the venting riser 6, if one of the venting risers 6 becomes blocked, the other venting riser 6 can be used for natural gas venting, ensuring the normal operation of the venting process. Support structures 7 are installed on the delivery pipe 5 and the venting riser 6, eliminating the need for ground support to ensure the stability of the venting riser 6. The rotating inner rod 703 and the rotating outer sleeve 704 are rotatably mounted on the first connecting sleeve 701 and the second connecting sleeve 702, respectively, and are movably connected. The angle can be adjusted according to the actual situation to ensure stable support for the discharge riser 6 without affecting the accurate installation of the discharge riser 6. The rainproof structure 8 can effectively prevent rainwater from entering the discharge riser 6 and causing corrosion. Through the structure of bearing 803, support rod 804, rotating rod 805, drive blade 808 and other structures, in rainy weather, the drive blade 808 will rotate due to the impact of rainwater and the influence of wind, thus rotating the rainproof cover 807. It can apply centrifugal force to throw out the rainwater, further improving the rainproof effect.

[0027] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
