[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1-6 This utility model provides a technical solution: an aluminum cast T-shaped gas pipe, including a T-shaped gas pipe body 1, with protective sleeves 2 fitted on both the left and right ends of the T-shaped gas pipe body 1. The protective sleeves 2 are circular tube structures with an "L" shaped cross-section, and the two protective sleeves 2 are symmetrically distributed about the bottom of the T-shaped gas pipe body 1. A connecting plate 8 is fixed to one end of the protective sleeve 2. The connecting plate 8 is an arc-shaped plate structure. A threaded post 9 is inserted and fixed to the end of the connecting plate 8 away from the protective sleeve 2. The threaded post 9 is a semi-cylinder. The threaded posts 9 at the ends of the two connecting plates 8 are joined to form a threaded stud. A nut 10 is screwed onto the stud.

[0023] The T-shaped gas pipe body 1 is installed in front of the gas straight pipes on both sides. Two protective sleeves 2 need to be put on both ends of the T-shaped gas pipe body 1 respectively. At this time, the two connecting plates 8 are close together, and the two threaded posts 9 are assembled into a stud. The nut 10 is put on and screwed onto the stud to lock it, so that the protective sleeve 2 is firmly installed on the T-shaped gas pipe body 1.

[0024] The protective sleeve 2 has a rubber cover 3 inside, and an insulation layer 6 is fixed inside the rubber cover 3. The rubber cover 3 and the insulation layer 6 are fitted onto the end of the T-shaped gas pipe body 1. When the rubber cover 3 is unfolded, the end of the rubber cover 3 protrudes from the end of the T-shaped gas pipe body 1. The end of the rubber cover 3 away from the protective sleeve 2 is integrally formed with a rubber extension cover 4. The rubber extension cover 4 is a frustum-shaped cover. The diameter of the end of the rubber extension cover 4 away from the rubber cover 3 is smaller than the outer ring diameter of the T-shaped gas pipe body 1. A rubber ring 5 is fixed to one end of the rubber extension cover 4. One end of the insulation layer 6 protrudes from the end of the T-shaped gas pipe body 1. The inner ring diameter of the insulation layer 6 is equal to the outer ring diameter of the T-shaped gas pipe body 1. An elastic plastic baffle 7 is fixed at the groove of the protective sleeve 2. The elastic plastic baffle 7 is an arc-shaped plate structure. There are two elastic plastic baffles 7, which are symmetrically distributed about the groove of the protective sleeve 2.

[0025] After fixing the T-shaped gas pipe body 1 (which can be welded) to the gas straight pipes on both sides, pry open the elastic plastic baffle 7 to deform it, and pull out the rubber cover 3 along with the rubber extension cover 4 and the insulation layer 6 from the protective sleeve 2. The unfolded rubber cover 3, rubber extension cover 4 and insulation layer 6 cover the outside of the connection between the T-shaped gas pipe body 1 and the gas straight pipe to protect the welded joint. When the T-shaped gas pipe body 1 is not installed or used, the rubber cover 3, rubber extension cover 4 and insulation layer 6 are inserted into the protective sleeve 2, and the elastic plastic baffle 7 is blocked in the groove of the protective sleeve 2 to prevent the rubber cover 3 from falling out of the protective sleeve 2.

[0026] The procedure for using cast aluminum T-type gas pipes is as follows:

[0027] Protective sleeves 2 are fitted onto both ends of the T-shaped gas pipe body 1, ensuring that the "L"-shaped structure of the protective sleeve 2 matches the T-shaped pipe structure. The position of the protective sleeve 2 is adjusted so that the two connecting plates 8 are close together and naturally aligned. The semi-cylindrical threaded posts 9 at the ends of the two connecting plates 8 are assembled into a complete stud. Nuts 10 are fitted onto the stud and rotated clockwise until they are tightened, ensuring the protective sleeve 2 is securely fixed to the T-shaped gas pipe body 1. The T-shaped gas pipe body 1 is positioned between the two straight gas pipes according to the design requirements. Using welding or other suitable fixing methods, the T-shaped gas pipe body 1 is firmly connected to the straight gas pipes on both sides. The elastic plastic baffle 7 is gently pried open to deform it, exposing the internal space of the protective sleeve 2. The assembly of the rubber cover 3, rubber extension cover 4, and insulation layer 6 is pulled out from the protective sleeve 2. The unfolded rubber cover 3 is placed over the weld between the T-shaped gas pipe body 1 and the straight gas pipes, ensuring that the frustum shape of the rubber extension cover 4 fits tightly against the pipe surface. Adjust the position of the rubber ring 5 to ensure it provides an additional seal at the port of the rubber extension cover 4. Wrap the insulation layer 6 around the outside of the rubber assembly to maintain a stable temperature in the welding area. If the T-shaped gas pipe body 1 is not in use temporarily, the rubber cover 3, rubber extension cover 4, and insulation layer 6 must be reinserted into the protective sleeve 2. Ensure the elastic plastic baffle 7 is reset and tightly secured in the groove of the protective sleeve 2 to prevent internal components from falling out.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
