Description

Y-shaped corrosion-resistant gas pipe Technical Field The utility model belongs to the technical field of kitchen pipelines, and particularly relates to a Y-shaped corrosion-resistant gas pipe. Background In the gas cooker, the gas pipe belongs to a common pipeline fitting and can be designed into various shapes, wherein the Y-shaped gas pipe is provided with double gas outlets and is used for connecting the cooker and the gas water heater. The existing gas pipe has the following defects that the gas pipe is connected with a gas inlet pipe through a pipe joint, the pipe joint is in threaded connection with the gas pipe, a sealing ring between the pipe joint and the gas pipe can be aged after the gas pipe is used for a period of time, so that the gas leakage phenomenon occurs, and the sealing ring needs to be replaced periodically. The prior patent document discloses a kitchen range gas pipe with a bent pipe interface (bulletin number: CN 217272645U), and the technical proposal of the kitchen range gas pipe is recorded with a threaded joint in which a threaded joint nut is in threaded connection, and the threaded joint is in threaded connection with a plug joint nut, so that once the situation of partial thread sliding occurs, the gas leakage phenomenon is easy to occur. Disclosure of Invention The utility model aims to solve the technical problems in the prior art, and provides the Y-shaped corrosion-resistant gas pipe which is novel in structure and good in sealing performance, and can effectively prevent gas from leaking from the joint of the pipe body and the pipe joint, and is reliable in use. In order to solve the technical problems, the utility model adopts the following technical scheme: The Y-shaped corrosion-resistant gas pipe comprises a pipe body, wherein the pipe body comprises a main pipe section and a V-shaped pipe section, the main pipe section is connected with the V-shaped pipe section, and the Y-shaped corrosion-resistant gas pipe is characterized in that one end of the main pipe section is connected with a pipe joint, the pipe joint comprises a middle end, a necking end and a reducing end, the middle end is arranged between the necking end and the reducing end, the maximum diameter of the reducing end is larger than the inner diameter of a pipe orifice of the main pipe section, the minimum diameter of the reducing end is smaller than the inner diameter of the pipe orifice of the main pipe section, an outer sealing sleeve is arranged on the middle end, the inner diameter of the outer sealing sleeve is matched with the outer diameter of the pipe orifice of the main pipe section, and the outer sealing sleeve is welded and fixed with the middle end.
