Description

Technical Field

[0001] This utility model belongs to the field of stove piping technology, and in particular relates to a Y-type corrosion-resistant gas pipe. Background Technology

[0002] In gas stoves, gas pipes are common pipe fittings that can be designed in various shapes. Among them, the Y-shaped gas pipe has two gas outlets and is used to connect the stove and the gas water heater.

[0003] The existing gas pipeline has the following defects: the gas pipeline is connected to the gas inlet pipe through a pipe joint, and the pipe joint is threaded to the gas pipeline. After a period of use, the sealing ring between the two will age, which will lead to gas leakage. The sealing ring needs to be replaced regularly.

[0004] Existing patent documents disclose "a gas pipe for a stove with a bent pipe interface" (publication number: CN217272645U). The technical solution describes a threaded connector with an internal threaded connection between the screw connector nut and the threaded connector and the plug connector nut. If the thread strips in some areas, gas leakage is likely to occur. Summary of the Invention

[0005] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a Y-type corrosion-resistant gas transmission pipe with novel structure, good sealing performance, effectively preventing gas leakage from the connection between the pipe body and the pipe joint, and reliable use.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A Y-type corrosion-resistant gas transmission pipe includes: a pipe body comprising a main pipe section and a V-shaped pipe section, the main pipe section being connected to the V-shaped pipe section; characterized in that: one end of the main pipe section is connected to a pipe fitting, the pipe fitting comprising an intermediate end, a constricted end, and a reducing end, the intermediate end being located between the constricted end and the reducing end, the maximum diameter of the reducing end being larger than the inner diameter of the main pipe section's opening, and the minimum diameter of the reducing end being smaller than the inner diameter of the main pipe section's opening; an outer sealing sleeve is provided on the intermediate end, the inner diameter of the outer sealing sleeve being adapted to the outer diameter of the main pipe section's opening, and the outer sealing sleeve being welded and fixed to the intermediate end. This gas transmission pipe has a novel structure, good sealing performance, effectively preventing gas leakage from the connection between the pipe body and the pipe fitting, and is reliable in use.

[0008] Furthermore, the main pipe section is symmetrically distributed with arc-shaped locking blocks. Each arc-shaped locking block has a horizontal part with a mounting through hole. By driving nails into the mounting through holes, the arc-shaped locking blocks are fixed to the mounting surface. The two symmetrically distributed arc-shaped locking blocks can limit the left and right swaying of the main pipe section, thus improving the stability of the main pipe section.

[0009] Furthermore, a positioning block is provided on the outer wall of the main pipe section, and a positioning sleeve hole corresponding to the positioning block is provided on the arc-shaped card block, so as to realize the quick positioning and installation of the arc-shaped card block on the main pipe section, reducing the positioning difficulty and replacing the welding fixing method, thus reducing the operation difficulty; when the arc-shaped card block is fixed by nails, the arc-shaped card block and the positioning block cannot be separated freely, and the assembly is reliable.

[0010] Furthermore, a first sealing ring is fitted onto the middle end, near the constricted end. When the middle end is fitted with the gas intake pipe, the first sealing ring tightly contacts the inner wall of the gas intake pipe to prevent gas leakage.

[0011] Furthermore, a first limiting groove corresponding to the first sealing ring is provided on the outer wall of the middle end, which can restrict the free sliding of the first sealing ring, improve the installation stability, and facilitate replacement.

[0012] Furthermore, both ends of the V-shaped pipe section are provided with constricted sections, and a second sealing ring is fitted onto the V-shaped pipe section, with the second sealing ring located near the constricted sections. The constricted sections facilitate the connection between the V-shaped pipe section and the matching pipeline, and the second sealing ring tightly abuts against the inner wall of the matching pipeline to prevent air leakage.

[0013] Furthermore, the outer wall of the V-shaped pipe section is provided with a second limiting groove corresponding to the second sealing ring, which can restrict the free sliding of the second sealing ring, improve installation stability, and facilitate replacement.

[0014] Furthermore, the V-shaped pipe section is equipped with an L-shaped support, and the L-shaped support has a strip-shaped mounting hole. Screws are driven into the strip-shaped mounting hole and fixed to the mounting surface to prevent the V-shaped pipe section from shaking freely, thereby improving the overall stability and making it easy to fix.

[0015] Furthermore, a corrosion-resistant layer is provided on the inner wall of the pipe, which improves the corrosion resistance of the inner wall of the pipe, making it less prone to corrosion and rust, and extending its service life.

[0016] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0017] 1. When installing the pipe fitting, first insert the reducing end into the opening of the main pipe section, and tap the pipe fitting until the reducing end cannot be inserted further, indicating that it is installed in place. Then, the outer sealing sleeve is fitted over the opening of the main pipe section. Weld the connection between the outer sealing sleeve and the main pipe section to form a whole, preventing the pipe fitting from loosening or falling off, and ensuring a firm installation. The reducing end is in close contact with the inner wall of the pipe opening, and the outer sealing sleeve is in close contact with the outer wall of the pipe opening, forming a double seal, which provides good sealing performance and makes it less prone to air leakage.

[0018] 2. The positioning hole on the arc-shaped card block is fitted onto the positioning block on the main pipe section, realizing the quick positioning and installation of the arc-shaped card block on the main pipe section, reducing the positioning difficulty and replacing the welding fixing method, thus reducing the operation difficulty; after the arc-shaped card block is fixed by nails, the arc-shaped card block and the positioning block cannot be separated freely, ensuring reliable assembly. The two symmetrically distributed arc-shaped card blocks can limit the left and right swaying of the main pipe section, improving the stability of the main pipe section. Attached Figure Description

[0029] One end of the main pipe section 2 is connected to a pipe connector 4, which is connected to the gas inlet pipe. The pipe connector 4 includes an intermediate end 5, a constricted end 6, and a reducing end 7. The intermediate end 5 is located between the constricted end 6 and the reducing end 7. The three are integrally formed, with a stable structure and no seams, making it less prone to gas leakage. The constricted end 6 facilitates the connection between the intermediate end 5 and the gas inlet pipe, reducing the assembly difficulty.

[0030] A first sealing ring 8 is fitted onto the middle end 5. The outer arc face of the first sealing ring 8 protrudes from the surface of the middle end 5 and is close to the constricted end 6. When the middle end 5 is fitted with the gas inlet pipe, the first sealing ring 8 is in close contact with the inner wall of the gas inlet pipe to prevent gas leakage.

[0031] The outer wall of the middle end 5 is provided with a first limiting groove corresponding to the first sealing ring 8, which can restrict the free sliding of the first sealing ring 8, improve the installation stability, and make replacement convenient.

[0032] The maximum diameter of the reducing end 7 is larger than the inner diameter of the main pipe section 2, and the minimum diameter of the reducing end 7 is smaller than the inner diameter of the main pipe section 2. The reducing end 7 can adapt to pipe openings of different diameters and has strong adaptability. An outer sealing sleeve 9 is provided on the intermediate end 5.
