[0002] The plastic three-way pipe joint is made of plastic and has three air vents. The three-way pipe joints currently in use are roughly divided into three types. The first type is a straight insertion type three-way pipe joint. The second type is a screw nut locking three-way pipe joint. The third type is a hot pressing type three-way pipe joint. The straight insertion type three-way pipe joint has the advantages of quick disassembly and assembly but the disadvantage of low pressure resistance and easy air leakage. The screw nut locking three-way pipe joint has the advantages of good fastening and convenient disassembly and assembly but the disadvantage of easy loosening of the nut due to thermal expansion and contraction, which leads to air leakage. The hot pressing type three-way pipe joint has the advantages of tight connection and resistance to air leakage but the disadvantage of being unable to disassemble and assemble. Therefore, there is a need for a plastic three-way pipe joint that is resistant to high pressure, resistant to air leakage, and capable of quick disassembly and assembly.
