Description

Technical Field

[0001] The utility model relates to the technical field of discharge pipes, in particular to a multifunctional gas discharge pipe. Background Art

[0002] During natural gas connection operations such as pipeline network renovation and new user development, the pipeline network needs to be vented and replaced. During the venting and replacement process, a vent pipe is required.

[0003] Existing bleed pipes have the following drawbacks during gas replacement operations: 1. They are extremely noisy, severely disrupting the normal lives of nearby residents, schools, hospitals, and other facilities. 2. Different bleed pipe sizes (e.g., DN32, DN40, DN50, etc.) are available for different bleed valves, requiring the use of different bleed pipes, making them inconvenient to carry. 3. During the operation, gas concentration and pressure must be tested in the gas valve well after the bleed pipe is removed from the gas valve, posing a safety hazard. Therefore, there is room for improvement. Utility Model Content

[0004] The utility model provides a multifunctional gas diffusion pipe to solve the problems raised in the background technology.

[0005] In order to solve the above problems, the present invention provides a multifunctional gas release pipe, including a release pipe body, the bottom end of the release pipe body is provided with a first threaded connection end, the top end is provided with a second threaded connection end, the first threaded connection end is threadedly connected to a connector head matching the gas valve, the second threaded connection end is threadedly connected to a gas muffler, a branch pipe connected to the release pipe body is fixedly provided on one side of the upper part of the release pipe body, and a third threaded connection end is provided at the end of the branch pipe away from the release pipe body, a pressure gauge is connected to the third threaded connection end, and an L-shaped detection tube is provided at the bottom of the branch pipe between the release pipe body and the third threaded connection end.

[0006] Preferably, a manual ball valve is provided in the discharge pipe body between the branch pipe and the second threaded connection end.

[0007] Preferably, a manual needle valve is provided in the L-shaped detection tube.

[0008] The beneficial effects of adopting the above technical solution are:

[0009] 1. The first threaded connection end at the bottom end of the discharge pipe body is convenient for connecting to connectors of different types of gas valves, so that only the discharge pipe body and connectors of multiple types need to be carried, thereby improving the convenience of carrying.

[0010] 2. By setting up the L-shaped detection tube and the connected pressure gauge in the branch pipe, the gas concentration detection and pressure detection can be carried out outside the gas valve well, which improves the safety of the work and avoids the installation and removal of the vent pipe every time the measurement is taken, thereby improving the work efficiency.

[0011] 3. By installing a gas silencer at the top of the vent pipe, it is possible to avoid generating loud noise during the replacement of the vent pipe, which may disturb surrounding residents, schools, hospitals, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0016] In the description of this utility model, unless otherwise specified, "plurality" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction, and therefore should not be construed as limiting this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, movable connections, or integral connections; they can refer to mechanical connections or electrical connections; and they can refer to direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0018] like Figure 1-2In this embodiment, a multifunctional gas release pipe includes a release pipe body 1, the bottom end of the release pipe body 1 is provided with a first threaded connection end 11, and the top end is provided with a second threaded connection end 12, the first threaded connection end 11 is threadedly connected to a connector 2 matching the gas valve, and the second threaded connection end 12 is threadedly connected to a gas muffler 3, a branch pipe 4 connected to the release pipe body 1 is fixedly provided on one side of the upper part of the release pipe body 1, and the end of the branch pipe 4 away from the release pipe body 1 is provided with a third threaded connection end 41, a pressure gauge 5 is connected to the third threaded connection end 41, and an L-shaped detection tube 6 is provided below the branch pipe 4 between the release pipe body 1 and the third threaded connection end 41.

At this time, the gas valve is opened to allow natural gas to enter the vent pipe body 1 for replacement. During replacement, the gas passes through the gas silencer 3 connected to the second threaded connection end 12 at the top of the vent pipe body 1, which can effectively reduce the noise generated during gas replacement, thereby avoiding interference with surrounding residents, schools, hospitals, etc. The pressure gauge 5 connected to the third threaded connection end 41 in the branch pipe 4 is convenient for external gas pressure measurement, and the setting of the L-shaped detection tube 6 is convenient for external detection of gas concentration, avoiding safety hazards caused by detection work in the valve well.

When performing replacement work, the discharge pipe body 1 is kept in an open and closed state, and then the replacement operation is carried out.

[0022] Preferably, a manual needle valve 61 is provided in the middle of the L-shaped detection tube 6 .

[0023] Through the above technical solution, the manual needle valve 61 is in an open and closed state when performing concentration detection.
