Description

Technical Field

[0001] This utility model relates to the field of municipal engineering technology, specifically a portable gas replenishment device combined with a quick-connect bridging gas replenishment device. Background Technology

[0002] Gas pipelines are pipeline systems used to transport gas, playing a vital role in gas supply. These gases generally include natural gas and manufactured gas. During daily production operations and emergency repairs, pressure needs to be released and reduced in pressure at pressure regulating stations and gate wells. In poor venting environments, venting must be carried out at gate wells. However, poor natural ventilation in well chambers can easily lead to the accumulation of toxic, harmful, flammable, and explosive substances or insufficient oxygen content. Furthermore, traditional connection methods are time-consuming and difficult to operate in the confined space of gate wells. Therefore, we need to propose a portable gas replenishment device combined with a quick-connect bridging gas replenishment device. Utility Model Content

A through pipe is fixedly connected to the top of the support frame. A first branch pipe is fixedly connected to the top of the through pipe. A second branch pipe is fixedly connected to the top of the through pipe. One end of the first branch pipe is fixedly connected to the second branch pipe. Both ends of the through pipe are fixedly connected to bridging pipes. One end of each of the two sets of bridging pipes is fixedly connected to a gas pipeline. The gas pipeline is located inside a valve well. The support frame is equipped with four sets of leveling components for keeping the through pipe horizontal. Four sets of casters are fixedly connected to the bottom of the support frame.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3This utility model provides a portable gas replenishment device combined with a quick-connect gas replenishment device, including a support frame 1. A through pipe 2 is fixedly connected to the top of the support frame 1. A first branch pipe 3 is fixedly connected to the top of the through pipe 2. A second branch pipe 4 is fixedly connected to the top of the through pipe 2. One end of the first branch pipe 3 is fixedly connected to the second branch pipe 4. Both ends of the through pipe 2 are fixedly connected to cross-connecting pipes 5. One end of the two sets of cross-connecting pipes 5 is fixedly connected to a gas pipeline 6. The gas pipeline 6 is located inside a valve well 7.

[0020] The support frame 1 is equipped with four sets of leveling components 8 for keeping the pipe 2 horizontal. The bottom of the support frame 1 is fixedly connected with four sets of casters 17. By setting the support frame 1, casters 17 and leveling components 8 together, the entire device can be moved easily. When the device is moved to the designated position, the leveling components 8 support and position the support frame 1.

[0021] When the ground at the construction site is uneven, the support frame 1 can be adjusted to a horizontal state by using the leveling component 8. This utility model can transform long-term, somewhat dangerous confined space operations into ground operations, greatly reducing the potential dangers of confined space operations. It makes operations that should have been carried out in the well chamber, which are somewhat difficult and dangerous, safer and simpler. It not only improves work efficiency, but also, based on the concept of "people-oriented", makes the working environment of employees safer, enabling employees to complete pressure reduction and emergency repair work more confidently, calmly, accurately and efficiently.

[0022] It is worth mentioning that a third branch pipe 9 is fixedly connected to the outer wall of the connecting pipe 2, and a bypass valve 10 is connected to the third branch pipe 9. All materials use standard pipe fittings of DN25, DN50, DN80, and DN100 for pipe connection, which can maximize the satisfaction of low-pressure gas gate well venting and pressure monitoring in gas production and emergency repair and rescue. DN25, DN50, DN80, and DN100 are numerical values ​​indicating the nominal diameter of the pipe fittings. They represent different sizes of pipe fittings. DN25 pipe fittings are pipe fittings with a nominal diameter of 25mm. Their actual outer diameter may vary depending on different standards and materials, but DN25... Generally considered a standard size specification; DN50 pipe fittings are pipe fittings with a nominal diameter of 50mm. These pipe fittings are also suitable for a variety of fluid transmission systems, and their dimensions and specifications conform to international or industry standards; DN80 and DN100 pipe fittings are pipe fittings with nominal diameters of 80mm and 100mm, respectively. These pipe fittings are usually used in fluid transmission systems that require large flow rates or pressures. They are made of various materials, including cast iron, steel, copper, and plastic, to meet the needs of different application scenarios; DN25, DN50, DN80, DN100, and other pipe fittings all follow international or industry standards, have uniform dimensions and specifications, and are easy to install and maintain.

[0023] This utility model also includes two sets of first venting valves 11, which are respectively connected to two sets of cross-connectors 5. Compared with the traditional venting operation installation connected in the well chamber, this device uses a flexible hose connection, which makes it more flexible in terms of space placement.

[0024] An inlet valve 12 is installed on the pipe 2, and an outlet valve 13 is installed on the side of the inlet valve 12 on the pipe 2. The connection of this device is not limited by the size of the well chamber and can be used in ordinary well chambers or directly buried gate wells, thus solving the dangers of working in confined spaces.

[0025] This utility model also includes a pressure regulator 14, which is connected to the through pipe 2 and is located between the inlet valve 12 and the outlet valve 13. This device can conveniently control the gas release on the ground and facilitate the observation of real-time pressure to stabilize the operating pressure.

[0026] The second branch pipe 4 is connected to the second vent valve 15 on its outer wall. The second branch pipe 4 is located below the second vent valve 15 and has a pressure-hanging and micro-venting point 16. In the past, the installation of the jumper gas supply device was cumbersome during emergency repairs. It had many parts and took a long time, with each installation taking nearly 45 minutes. In addition, during the welding and leak repair process, a low pressure and high stability were required. The valve had to be opened repeatedly or the venting and depressurization procedure had to be repeated to adjust the pressure. This made it impossible to guarantee the accuracy of the working pressure and caused unnecessary waste and gas loss. This device is assembled with standard materials, which makes it easier to promote and use. It is flexible and easy to move, easy to assemble and disassemble, has low gas loss, is easy to carry, and has a small footprint.

[0027] Specifically, the leveling component 8 includes a threaded post 801, which is threaded to the top of the support frame 1. The bottom end of the threaded post 801 passes through the support frame 1 and is fixedly connected to a support pad 802. The top end of the threaded post 801 is fixedly connected to an adjusting handwheel 803. By rotating the adjusting handwheel 803, the threaded post 801 can be rotated, which in turn can move the support pad 802 until the support pad 802 is in close contact with the ground, thereby achieving the effect of positioning and supporting the support frame 1 and leveling it.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
