The difference between the embodiment and the embodiment is that an annular groove is formed in the opposite surface of the first pipe 1 and the second pipe 2, a sealing ring 9 is arranged in the annular groove, and the sealing ring 9 is partially positioned on the outer side of the annular groove, so that the sealing ring 9 can be extruded and deformed to seal the joint between the first pipe 1 and the second pipe 2. Wherein the annular groove is provided on an end face of the first tubular 1 and/or the second tubular 2. After the end surfaces of the first pipe 1 and the second pipe 2 are in sealing butt joint with the sealing ring 9, part of the tensioning screw 7 is located between the first pipe 1 and the second pipe 2, so that the tightness of the sealing ring 9 can be changed by rotating the locking nut 8. Optionally, the sealing ring 9 is an annular sealing ring 9, and the sealing ring 9 may be made of a rubber material.
The plastic pipes are generally connected through a plurality of pipe sections, the joints of the adjacent pipe sections need to be sealed, if the pipe and the pipe are in hard contact, gaps can be generated at the joints, at the moment, the sealing rings 9 are used for sealing and connecting the joints, the tension of the existing sealing rings 9 after being fixed cannot be adjusted generally, and gaps can be generated after the existing sealing rings 9 are used for a period of time, so that the sealing is not tight, in the embodiment, after the end surfaces of the first pipe 1 and the second pipe 2 are in sealing and abutting joint with the sealing rings 9, part of the tensioning screw 7 is positioned between the first pipe 1 and the second pipe 2, so that the length of the tensioning screw 7 positioned between the first pipe 1 and the second pipe 2 can be changed by rotating the locking nut 8, the tension of the sealing rings 9 can be changed, even if gaps are generated after the existing sealing rings are used for a period of time, the tightness of the sealing ring 9 can be adjusted according to the requirement, and the phenomenon of untight sealing is improved.
The difference between the first embodiment and the second embodiment is that the inner walls of the first pipe 1 and the second pipe 2 are covered with an alloy layer 10, and the alloy layer 10 is a nickel-phosphorus alloy layer, so that the plastic pipe has the advantages of good wear resistance, strong corrosion resistance, light weight, long service life, simple process and low cost.
In summary, according to the plastic pipe with the wear prompt function and convenient to replace, the first pipe 1 and the second pipe 2 comprise the pipe body 3 and the wear prompt layer 4 arranged in the pipe body 3, the color of the wear prompt layer 4 is different from that of the pipe body 3, when the pipe body 3 is worn to the safety line position, the wear prompt layer 4 is exposed, so that the plastic pipe can be reminded to be replaced in time in a certain form, meanwhile, the outer wall of the first pipe 1 is provided with the first annular bulge 5, the outer wall of the second pipe 2 is provided with the second annular bulge 6, and the first annular bulge 5 and the second annular bulge 6 are fixed through the tensioning screw 7 and the locking nut 8, so that the plastic pipe with the wear prompt function is stable in structure and convenient to disassemble and assemble, and the use and maintenance cost is reduced.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
