Description

Technical Field

[0001] The utility model relates to the technical field of polypropylene PP-R pipelines, in particular to a polypropylene PP-R pipeline with impact resistance. Background Art

[0002] : PPR is the abbreviation of type III polypropylene, also known as random copolymer polypropylene pipe. It adopts hot-melt welding, has special welding and cutting tools, has high plasticity, and is very economical in price. It has an additional insulation layer, better thermal insulation performance, and the pipe wall is also smooth. It does not include the joints of internal and external threads. It is generally used for embedded walls or deep well pre-buried pipes. PPR pipes are moderately priced, stable in performance, heat-resistant and heat-insulating, corrosion-resistant, smooth in the inner wall without scaling, safe and reliable in the pipeline system, and impermeable. The service life can reach 50 years, but the construction technology requirements are high. Special tools and professionals are required for construction to ensure the safety of the system. PP-R pipe is also called tri-propylene polypropylene pipe. It adopts random copolymer polypropylene through extrusion to become pipe material and injection molding to become pipe fittings. It is a new type of plastic pipe product developed and applied in Europe in the early 1990s. PP-R is a new generation of pipe material in the late 1980s, which uses gas phase copolymerization process to make about 5% PE randomly and uniformly polymerized (random copolymerization) in the molecular chain of PP. It has good impact resistance and long-term creep performance.

[0003] Although the existing pipelines have good thermal insulation performance, their overall impact resistance is poor. When the pipelines are impacted by external forces, the pipelines are prone to bending, which is not conducive to long-term use. Therefore, a polypropylene PP-R pipeline with impact resistance is proposed to solve the above-mentioned problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a polypropylene PP-R pipe with impact resistance, which solves the problem that the pipe is easily bent when impacted by external force due to poor overall impact resistance, which is not conducive to long-term use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a polypropylene PP-R pipe with impact resistance, comprising a first pipe body, a second pipe body, a first fixing ring and a second fixing ring, wherein the first pipe body and the second pipe body are both provided with impact resistance components on their exteriors;

[0006] The impact-resistant component includes a mounting sleeve that is clamped on the outer surfaces of the first pipe body and the second pipe body, a positioning hole is opened at the bottom of the mounting sleeve, a fixing pin is pinned inside the positioning hole, a plurality of dampers are fixedly connected to the outer surface of the mounting sleeve, a buffer sleeve is fixedly connected to the top of the damper, and a film is bonded to the top of the buffer sleeve.

[0007] Furthermore, the outer surfaces of the first pipe body and the second pipe body are fixedly connected with connecting rings, the outer surfaces of the connecting rings, the first fixing ring and the second fixing ring are all provided with threaded holes, and the internal threads of the threaded holes are connected with connecting screws.

[0008] Furthermore, a buckle is fixedly connected to the outer surface of the first fixing ring, and a fixing block is fixedly connected to the outer surface of the second fixing ring.

[0009] Furthermore, the buckle matches the size of the fixing block, and the buckle is engaged with the fixing block.

[0010] Furthermore, the mounting sleeve is made of plastic and has good toughness as a whole.

[0011] Furthermore, the first fixing ring and the second fixing ring are consistent in size, and the inner diameters of the first fixing ring and the second fixing ring are larger than the outer diameters of the first pipe body and the second pipe body.

[0012] Furthermore, sealing gaskets for enhancing sealing properties are bonded to the top ends of the first pipe body and the second pipe body, and the sealing gaskets are made of rubber.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. The impact-resistant polypropylene PP-R pipe can make the first pipe body and the second pipe body have good impact resistance by setting an impact-resistant component. When in use, it is only necessary to break open the installation sleeve and clamp it on the outer surface of the first pipe body and the second pipe body, and then insert the fixing pin into the positioning hole to limit the position of the installation sleeve to avoid falling off. When the pipe is impacted by external force, the buffer sleeve and the plurality of dampers cooperate to achieve a buffering effect, thereby absorbing most of the impact force from the outside, avoiding the bending of the first pipe body and the second pipe body, and being more conducive to long-term use. In addition, the film can also achieve an anti-fouling effect.

[0015] 2. The impact-resistant polypropylene PP-R pipe can facilitate workers to quickly connect multiple pipes for extended use through the cooperation of connecting rings, threaded holes, connecting screws, buckles and fixing blocks. It is relatively convenient. The installation sleeve made of plastic material with good toughness can be easily opened by workers and is not prone to breakage. By setting a sealing gasket made of rubber material, the sealing of the pipes after connection can be enhanced, thereby avoiding water leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 In this embodiment, a polypropylene PP-R pipe with impact resistance includes a first pipe body 1, a second pipe body 2, a first fixing ring 9 and a second fixing ring 10, and the first pipe body 1 and the second pipe body 2 are both provided with impact resistance components on the outside;

[0023] The impact-resistant component includes a mounting sleeve 3 which is clamped on the outer surfaces of the first pipe body 1 and the second pipe body 2. A positioning hole 4 is provided at the bottom of the mounting sleeve 3. A fixing pin 5 is pinned inside the positioning hole 4. A plurality of dampers 6 are fixedly connected to the outer surface of the mounting sleeve 3. A buffer sleeve 7 is fixedly connected to the top of the damper 6. A film 8 is bonded to the top of the buffer sleeve 7. By setting the impact-resistant component, the first pipe body 1 and the second pipe body 2 can have good impact resistance. When in use, it is only necessary to pry open the mounting sleeve 3 and clamp it on the outer surfaces of the first pipe body 1 and the second pipe body 2, and then insert the fixing pin 5 into the positioning hole 4 to limit the position of the mounting sleeve 3 to avoid falling off. When the pipe is impacted by external force, the buffer sleeve 7 and the plurality of dampers 6 cooperate to achieve a buffering effect, thereby absorbing most of the external impact force, avoiding the bending of the first pipe body 1 and the second pipe body 2, and being more conducive to long-term use. In addition, the film 8 can also achieve an anti-fouling effect.

[0024] Among them, the outer surfaces of the first pipe body 1 and the second pipe body 2 are fixedly connected with a connecting ring 11, and the outer surfaces of the connecting ring 11, the first fixing ring 9 and the second fixing ring 10 are all provided with threaded holes 12, and the internal threads of the threaded holes 12 are connected with connecting screws 13, the outer surface of the first fixing ring 9 is fixedly connected with a buckle 14, and the outer surface of the second fixing ring 10 is fixedly connected with a fixing block 15, the sizes of the buckle 14 and the fixing block 15 match, and the buckle 14 is clamped with the fixing block 15. Through the cooperation of the connecting ring 11, the threaded hole 12, the connecting screws 13, the buckle 14 and the fixing block 15, it is convenient for the staff to quickly connect multiple pipes for extended use, which is more convenient.

[0025] It should be noted that the material of the installation sleeve 3 is plastic, and the installation sleeve 3 has good toughness as a whole. The installation sleeve 3 made of plastic and having good toughness can be easily opened by the staff, and at the same time, it is not easy to break.

[0026] It should be understood that the first fixing ring 9 and the second fixing ring 10 are of the same size, the inner diameters of the first fixing ring 9 and the second fixing ring 10 are larger than the outer diameters of the first pipe body 1 and the second pipe body 2, and sealing gaskets 16 for enhancing the sealing are bonded to the tops of the first pipe body 1 and the second pipe body 2. The sealing gaskets 16 are made of rubber. By providing the sealing gaskets 16 made of rubber, the sealing of the pipes after docking can be enhanced, thereby avoiding water leakage.

[0027] The working principle of the above embodiment is:

[0028] When using the impact-resistant polypropylene PP-R pipe, it is only necessary to pry open the installation sleeve 3 and clamp it on the outer surface of the first pipe body 1 and the second pipe body 2, and then insert the fixing pin 5 into the positioning hole 4 to limit the position of the installation sleeve 3 to prevent it from falling off. When the pipe is impacted by external force, the cooperation of the buffer sleeve 7 and multiple dampers 6 can achieve a buffering effect, thereby absorbing most of the impact force from the outside, avoiding the bending of the first pipe body 1 and the second pipe body 2, and being more conducive to long-term use. In addition, when it is necessary to dock the pipes, the staff first needs to install and fix the first fixing ring 9 and the second fixing ring 10 to the connecting end of the first pipe body 1 and the second pipe body 2 through the cooperation of the threaded hole 12 and the connecting screw 13, and then make the connecting end faces of the first pipe body 1 and the second pipe body 2 fit together, and then, the buckle 14 is successively inserted into the outer surface of the fixing block 15, so that the first pipe body 1 and the second pipe body 2 can be quickly docked, which is convenient for extended use and more convenient.
