Description

Technical Field

[0001] The utility model relates to the field of gas supply, and particularly relates to an adjusting structure of a gas supply device. Background Art

[0002] Gas supply refers to the facility of transporting natural gas to households or for industrial use through pipelines. A gas supply system usually consists of a gas supply pipeline, a pressure regulating device, a metering instrument, etc., to ensure that natural gas is delivered to users under safe and stable pressure. An increase in gas supply volume may require installing larger-diameter pipelines or adjusting the pressure regulating equipment to meet the needs of daily life and equipment use.

[0003] With the popularization of gas, in order to further meet people's needs, it is usually necessary to increase the gas supply volume. When additional gas is supplied to existing gas, a tee pipe is often used in cooperation with a valve and a gas chamber for gas supply operation. Since the gas inlet points are in an aggregated state, the impact during gas supply is relatively large, and it is easy to cause vibration of the main pipeline. Summary of the Utility Model

[0025] To make the objectives, technical solutions, and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present utility model.

[0026] First Embodiment:

[0027] See Figures 1-5 As shown, the present utility model provides an adjustment structure for a gas supply device, including a communicating outer pipe 1. The communicating outer pipe 1 has a cylindrical structure, corresponding to the gas supply pipeline, and is connected to the gas supply pipeline through a flange. A guiding frame 2 is connected to the inner wall of the communicating outer pipe 1. A receiving cavity is formed between the guiding frame 2 and the communicating outer pipe 1. An intake pipe 4 communicating with the receiving cavity is connected to the side wall of the communicating outer pipe 1. The external opening of the intake pipe 4 is connected to a gas supply chamber through a valve. The bottom of the receiving cavity is connected with a gas delivery bottom plate 3 for sealing it. A plurality of gas delivery holes 301 penetrate through the gas delivery bottom plate 3, and the bottom ends of the gas delivery holes 301 extend towards the axis of the communicating outer pipe 1. When the communicating outer pipe 1 is installed in the main gas transmission pipeline, when the gas volume in the main pipeline needs to be increased, the valve outside the intake pipe 4 is opened, and the gas in the gas supply chamber can be drained into the receiving cavity through the intake pipe 4, and the increased gas can be guided into the communicating outer pipe 1 and the inside of the main pipeline through the gas delivery holes 301 at the bottom of the receiving cavity. This structure can drain the gas through a plurality of gas delivery holes 301, which can evenly increase the gas volume and reduce the vibration during the transmission of the main pipeline.

[0028] Furthermore, an anti-corrosion layer is provided on the outer walls of the communicating outer pipe 1 and the intake pipe 4, which can play a role in anti-corrosion protection and increase the service life of the device.

[0029] Second Embodiment, the different features from the first embodiment are as follows:

[0030] A vulcanized rubber layer 5 is provided on the inner wall of the receiving cavity and the inner wall of the intake pipe 4. The vulcanized rubber layer 5 is used to achieve buffer protection for the inner wall of the receiving cavity. The gas delivery holes 301 are arranged in a spiral shape and are circumferentially distributed with the axis of the communicating outer pipe 1 as the reference. The top of the guiding frame 2 is a conical surface extending towards the inner wall of the communicating outer pipe 1, and the bottom of the guiding frame 2 is a cylindrical structure. When the device is installed in the main transmission pipeline, the conical surface on the guiding frame 2 can be used to drain the gas in the main pipeline, thereby reducing the impact, and cooperating with the gas delivery holes 301 on the gas delivery bottom plate 3 to transport and guide the externally added gas, assisting the feeding of the gas, and making the gas transmission more stable.

[0031] During processing, the connection between the outer tube 1, the guiding frame 2, and the air supply bottom plate 3 is achieved by welding at the connection positions.

[0032] Furthermore, the vulcanized rubber layer 5 on the guiding frame 2 that contacts the air supply bottom plate 3 is conically arranged. With this arrangement, when the air supply bottom plate 3 is installed with the guiding frame 2 by a post-installation method, the cone at the contact position between the vulcanized rubber layer 5 and the air supply bottom plate 3 forms a seal for the air supply bottom plate 3. The inner wall of the air supply bottom plate 3 is provided with a stepped through-hole 302 corresponding to the guiding frame 2. When the air supply bottom plate 3 is connected to the guiding frame 2, the contact area between the air supply bottom plate 3 and the guiding frame 2 is larger, and the connection is more reliable.

[0033] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
