[0002] Natural gas transmission and distribution is the entire process of safely and efficiently delivering natural gas from the gas source to end users, covering long-distance transmission, storage and peak shaving, and urban gas distribution. This system is a core component of energy infrastructure and has characteristics such as high pressure, flammability and explosiveness, and strong continuity, and must strictly follow safety regulations and technical standards.

[0003] In the existing technology, during the natural gas transmission and distribution process, the transmission and distribution system delivers natural gas to different output pipes according to usage requirements. In order to ensure the stability of natural gas output inside the output pipe, it is necessary to detect the gas pressure inside the pipeline. However, conventional gas pressure detection devices will be damaged when the pressure is too high, and cannot issue timely warnings when the pressure is too high, which poses a significant safety hazard. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in order to ensure the stability of natural gas output from the pipeline, it is necessary to detect and process the gas pressure inside the pipeline. However, conventional gas pressure detection devices will be damaged when the pressure is high and cannot issue timely warnings when the pressure is high, which poses a significant safety hazard. Therefore, this invention proposes a natural gas pipeline distribution system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A natural gas pipeline transmission and distribution system includes a transmission and distribution module. A gas transmission pipe is fixedly connected to the side wall of the transmission and distribution module. Multiple branch pipes are fixedly connected to the wall of the gas transmission pipe. A pump body is fixedly connected to the end of the transmission and distribution module opposite to the gas transmission pipe. An induction cylinder is fixedly connected to the wall of the branch pipe. A piston is slidably provided on the inner wall of the induction cylinder. A controller is fixedly connected to the inner wall of the induction cylinder. A pressure sensor is fixedly connected to the end of the controller located inside the induction cylinder. An adapter block is fixedly connected to the side wall of the controller. A wire is provided on the side wall of the adapter block. A conduit is electrically connected to the top of the transmission and distribution module. The wire passes through the conduit and is electrically connected to the transmission and distribution module.

[0007] Preferably, a support frame is fixedly connected to the end of the gas pipeline that is away from the gas distribution module.

[0008] Preferably, a spring is fixedly connected to the inner wall of the induction cylinder, and the spring is pressed against the side wall of the piston.

[0009] Preferably, a pressure plate is fixedly connected to the piston on one side relative to the spring, and the pressure plate is aligned with the pressure sensor.

[0011] Preferably, the springs are respectively sleeved on the outside of the controller and the pressure plate.

[0012] Compared with the prior art, the present invention provides a natural gas pipeline transmission and distribution system, which has the following beneficial effects:

[0013] 1. This natural gas pipeline distribution system can drive a pump to transport and process natural gas through the distribution module, so that the natural gas is output through the gas transmission pipe and the distribution pipe. According to the different natural gas pressure inside the distribution pipe, the piston can be pushed to different positions on the inner wall of the sensing cylinder, so that the spring is compressed to different degrees, which can make the pressure sensor detect the pressure change. The controller can transmit electrical signals to the inside of the distribution module through the adapter block, wires and conduits, which can issue early warnings in a timely manner to remind the staff to take action.

[0014] 2. In this natural gas pipeline distribution system, the pressure plate can improve the uniformity of the force on the pressure sensor, while the sealing rubber ring can improve the sealing performance of the piston on the inner wall of the sensing cylinder. Attached Figure Description
