Detailed Implementation

[0022] 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.

[0023] See Figures 1 to 5 This embodiment discloses a gas pressure regulating component, including a pressure regulator 200, an inlet component 100, and an outlet component 400. Gas enters the pressure regulator 200 through the inlet component 100 and then enters the outlet component 400.

[0024] The inlet assembly 100 includes a functional pipe 110 and an inlet pipe 120, which are threaded together. The functional pipe 110 includes a first pipe body 111 extending vertically and a second pipe body 112 extending horizontally. The first pipe body 111 and the second pipe body 112 are integrally formed. A ball valve 700 is installed at the end of the first pipe body 111 near the inlet pipe 120 for opening and closing the gas intake. A filter 800 is installed at the connection between the first pipe body 111 and the second pipe body 112 for filtering impurities in the gas. The inlet end of the inlet pipe 120 is designated as the first inlet end 130, and the outlet end of the second pipe body 112 is designated as the first outlet end 140.

[0025] The pressure regulator 200 has a second inlet end 210 and an outlet end 220. The first outlet end 140 and the second inlet end 210 are connected by a first connecting pipe 300. The first connecting pipe 300 includes a structural section 310, with a first connecting section 320 and a second connecting section 330 at each end, both threaded. The opening of the first connecting section 320 is the third inlet end 301, and the opening of the second connecting section 330 is the third outlet end 302. The first connecting section 320 is inserted into the first outlet end 140 and connected to it via a threaded engagement, thereby fixing the first connecting pipe 300 to the inlet assembly 100. A union nut 900 is installed at the second inlet end 210, and the second connecting section 330 is threadedly connected to the union nut 900, thereby fixing the first connecting pipe 300 to the pressure regulator 200.

[0026] The outlet assembly 400 includes a third pipe body 410 and an outlet pipe 420, which are connected by a threaded connection. The inlet of the third pipe body 410 is a fourth inlet end 430, and the outlet of the outlet pipe 420 is a fourth outlet end 440. A ball valve 700 is also installed inside the third pipe body 410 for opening and closing the gas outlet.

[0027] The pressure regulator 200 and the outlet assembly 400 are connected via a second connecting pipe 500. Specifically, a union nut 900 is provided at the fourth inlet end 430. One end of the second connecting pipe 500 is threadedly connected to the union nut 900, and the other end is threadedly connected to the second outlet end 220. The second connecting pipe 500 allows for fine-tuning during assembly, facilitating the installation between the outlet assembly 400 and the pressure regulator 200.

[0028] The second inlet end 210 is arranged horizontally, the second outlet end 220 is arranged vertically, and the third pipe body 410 is also arranged vertically, thus making the third pipe body 410 parallel to the first pipe body 111. The first connecting pipe 300 serves as a transition between the inlet component 100 and the pressure regulator 200, and is an extension of the second pipe body 112; therefore, the first connecting pipe 300 is arranged horizontally. The first connecting pipe 300 is connected to the inlet component 100 and the pressure regulator 200 via a threaded connection, making assembly and disassembly convenient. For different construction scenarios, the required distance between the inlet component 100 and the outlet component 400 varies. By replacing the first connecting pipe 300 with different lengths, different requirements can be met without producing functional pipes 110 of different lengths in the second pipe body 112, reducing production costs. Simultaneously, the threaded connection allows for fine-tuning during assembly, facilitating assembly and providing redundancy for errors during construction.

[0029] To ensure the sealing performance between the first connecting pipe 300 and the first outlet end 140, an installation groove 141 is provided at the second outlet end 220. A sealing ring 142 is embedded in the installation groove 141. The diameter of the structural section 310 is larger than that of the first connecting section 320 and the second connecting section 330. When the first connecting pipe 300 is connected to the second outlet end 220, the platform formed between the structural section 310 and the first connecting section 320 abuts against the sealing ring 142, thereby ensuring the sealing performance.

[0030] The second tube 112 is provided with a reserved opening 118, which is normally sealed with a plug. Various sensors can be installed at the reserved opening 118 according to actual needs. To allow for a relatively long length of space for the installed sensors, the second tube 112 also has reinforcing members on the functional tube 110. The reinforcing members include a first reinforcing plate 113 and a second reinforcing plate 114. The first reinforcing plate 113 extends from the upper corner of the connection between the first tube 111 and the second tube 112 to the first outlet end 140, and the second reinforcing plate 114 extends from the lower corner of the connection between the first tube 111 and the second tube 112 to the first outlet end 140. The second reinforcing plate 114 includes a first side 115 connecting the first tube 111 and a second side 116 connecting the second tube 112. A third side 117 is located between the first side 115 and the second side. The third side 117 has an arc-shaped structure to prevent stress concentration and further ensure structural strength.

[0031] Both the inlet pipe 120 and the outlet pipe 420 are connected to the external gas pipeline via flanges 600. Retaining rings 620 are installed at the first inlet end 130 and the fourth outlet end 440. Flanges 600 are provided with annular grooves 610 corresponding to the positions of the retaining rings 620. During assembly, the retaining rings 620 are embedded in the annular grooves 610, allowing the flanges 600 to move during installation. This provides more pressure regulation space when the inlet pipe 120 and outlet pipe 420 are connected to the external pipeline via flanges 600, offering redundancy for assembly errors and further facilitating installation.

[0032] The outer wall of the first connecting pipe 300 is provided with a groove 311, which provides a force application point for rotating the first connecting pipe 300, thereby facilitating the installation of the first connecting pipe 300.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
