[0025] Example 1: Please refer to Figures 1 to 4 :

[0026] The utility model provides a high-temperature resistant CPVC four-way pipe fitting, comprising: a four-way pipe 1; the four-way pipe 1 is in a cross-shaped structure; the four-way pipe 1 selects high-performance CPVC resin as a base material, and improves the high-temperature resistance and processing performance of the CPVC material by adding auxiliary materials such as stabilizers, antioxidants and plasticizers; anti-slip grooves 101 are respectively opened on the annular side walls of the outer ends of the four-way pipes 1; the inner cavities of the four openings of the outer ends of the four-way pipes 1 are respectively opened with docking notches 102; fixing rings 103 are respectively fixedly installed on the side walls of the outer ends of the four-way pipes 1; connecting pipes 2 are respectively inserted in the four openings of the outer ends of the four-way pipes 1, and the structures on the four connecting pipes 2 are consistent; the connecting pipes 2 are inserted at the docking notches 102, and at this time, the docking part between the connecting pipes 2 and the inner cavity side walls of the four-way pipes 1 is smooth, Anti-skid grooves 201 are evenly arranged on the annular side wall of the connecting pipe 2. The anti-skid patterns 101 and the anti-skid grooves 201 have an anti-skid effect. When the four-way pipe 1 is installed by grasping the anti-skid patterns 101 and the anti-skid grooves 201, there will be no hand slipping, which prevents the four-way pipe 1 from slipping when the installation is forced. There is a sealing rubber ring 202 on the annular side wall of the connecting pipe 2. The connecting pipe 2 is glued with the upper sealing ring 3 and the lower sealing ring 304 at the joints. The sealing rubber ring 202 is used to seal this place to prevent the liquid in the four-way pipe 1 from seeping out from the joints here. The sealing rubber ring 202 has good sealing performance on the connecting part of the four-way pipe 1 and high pressure resistance. The upper sealing rings 3 are respectively installed at the upper ends of the annular side walls at the outer ends of the four-way pipe 1, and the structures on the four upper sealing rings 3 are consistent.

[0027] Among them, an upper groove 301 is opened in the middle of the concave surface of the upper sealing ring 3. After the upper sealing ring 3 and the lower sealing ring 304 are connected, the plug block 303 will be inserted into the slot 306, and then screws are used to penetrate the circular holes of the lower sealing ring 304 and the plug block 303 at the lower end of the upper sealing ring 3, and the lower sealing ring 304 and the upper sealing ring 3 are fixed with screws. At this time, the upper groove 301 and the lower groove 305 wrap the fixing ring 103, and also seal the connecting pipe 2 inserted in the fixing ring 103. The upper sealing ring 304 is butt-jointed with a lower sealing ring 304, and through-holes are respectively provided at the two ends of the upper sealing ring 3, through-holes are respectively provided at the two ends of the upper end of the lower sealing ring 304, through-holes are respectively provided at the two ends of the upper end of the lower sealing ring 304, through-screws are inserted in the through-holes, a lower card slot 305 is provided in the middle of the inner concave surface of the lower sealing ring 304, and slots 306 are respectively provided at the two ends of the top of the lower sealing ring 304.

[0028] Among them, a fastening ring 4 is slidably installed on the side wall of the upper sealing ring 3, and the structure on the fastening ring 4 is consistent; guide blocks 401 parallel to each other are fixedly installed on the side wall of the fastening ring 4; the guide blocks 401 are slidably installed in the guide grooves 302, and when the fastening ring 4 slides up and down, the guide blocks 401 are restricted by the guide grooves 302, and the fastening ring 4 can only slide up and down to prevent the fastening ring 4 from deflecting or tilting when sliding up and down, and the upper and lower fastening rings 4 cannot be docked, and anti-skid grooves 402 are evenly opened on the inner concave surface of the fastening ring 4, and the upper and lower fastening rings When docking, first slide the upper fastening ring 4 downward, then dock the lower fastening ring 4 with the upper fastening ring 4, and fasten the upper and lower fastening rings 4 with the screws on the fixing ear plates 403. At this time, the upper and lower anti-slip grooves 402 will squeeze the four-way pipe 1, and also fix and squeeze the connecting pipe 2 inserted into the four-way pipe 1 to prevent the connecting pipe 2 from being withdrawn from the four-way pipe 1. The two ends of the fastening ring 4 are respectively fixedly installed with symmetrical fixing ear plates 403, and a penetrating circular hole is opened in the middle of the fixing ear plate 403, and a penetrating screw is inserted in the circular hole.

[0029] Embodiment 2, based on embodiment 1, as Figure 1 and Figure 4 As shown, the anti-skid pattern 101 is removed to make the outer wall of the cross-way pipe 1 smooth and beautiful. When installing the cross-way pipe 1, hold the pipes at the other two ends of the cross-way pipe 1, so that the hands will not slip, which prevents the hands from slipping when applying force to install the cross-way pipe 1, and saves the time and financial cost of opening the anti-skid pattern 101.

[0030] The working principle of this embodiment is as follows: when in use, first insert the connecting pipe 2 into the docking notch 102. At this time, the docking place between the connecting pipe 2 and the inner cavity side wall of the four-way pipe 1 is smooth. After the upper sealing ring 3 and the lower sealing ring 304 are docked, the plug 303 will be inserted into the slot 306, and then the screws are penetrated through the circular holes of the lower sealing ring 304 and the plug 303 at the lower end of the upper sealing ring 3, and the lower sealing ring 304 and the upper sealing ring 3 are fixed with screws. At this time, the upper card groove 301 and the lower card groove 305 wrap the fixing ring 103, and also seal the connecting pipe 2 inserted in the fixing ring 103. When liquid flows in the four-way pipe 1 and the connecting pipe 2, it will not leak. When the two fastening rings 4 are butted together, the upper fastening ring 4 is first slid downward, and then the lower fastening ring 4 is butted against the upper fastening ring 4, and the upper and lower fastening rings 4 are fastened with the screws on the fixing ear plate 403. At this time, the upper and lower anti-slip grooves 402 will squeeze the four-way pipe 1, and also fix and squeeze the connecting pipe 2 inserted into the four-way pipe 1 to prevent the connecting pipe 2 from being withdrawn from the four-way pipe 1. The connecting pipe 2 is glued with the upper sealing ring 3 and the lower sealing ring 304 at the butt joint with the sealing rubber ring 202 to seal this place to prevent the liquid in the four-way pipe 1 from seeping out from the butt joint here. The sealing rubber ring 202 has good sealing performance on the connecting part of the four-way pipe 1 and high pressure resistance.
