Description

Technical Field

[0001] The utility model relates to the technical field of PE pipes, in particular to a high-strength anti-oxidation PE pipe. Background Art

[0002] PE pipe is polyethylene. Generally, the application range of PE pipe water supply pipe is below 40 degrees Celsius, and it cannot be used for hot water delivery pipes. PE pipe is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and it is translucent to a certain extent in thin cross-sections. PE has excellent resistance to most domestic and industrial chemicals.

[0003] Existing PE pipes are mostly damaged by oxidation corrosion during use in two ways: 1. After the outer wall and anti-oxidation layer are damaged by external impact, the PE pipe is easily directly damaged by oxidation; 2. After corrosive liquid drips on the PE pipe, it will corrode and penetrate the anti-oxidation layer on the outer wall of the PE pipe, causing oxidation damage to the PE pipe; and existing PE pipes are difficult to replace after oxidation damage. Therefore, it is necessary to improve the design of a high-strength, anti-oxidation PE pipe. Utility Model Content

[0004] Based on this, it is necessary to provide a high-strength, antioxidant PE pipe to address the above technical problems.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a high-strength, antioxidant PE pipe, including a main body, wherein the main body is provided with a plurality of inclined annular grooves, adjacent inclined annular grooves are symmetrically arranged, and a plurality of V-shaped frames are installed in the inclined annular grooves, and an antioxidant layer is provided on the side of the V-shaped frame close to the outer wall of the main body, and adjacent V-shaped frames are abutted, and a discharge annular groove is provided on the main body, and the discharge annular groove is connected to the lowest end of the V-shaped frame, and a discharge port is provided at the bottom end of the discharge annular groove; interface one and interface two are installed on the main body, and interface one and interface two are both located on the higher end side of the inclined annular groove, interface one is provided with a through groove, and an elastic card block is installed on interface two; when the elastic card block is clamped in the through groove, interface one abuts and seals with interface two; a sealing block is threadedly connected to interface one, and an extrusion mechanism for squeezing the elastic card block out of the through groove is installed on the sealing block, and the sealing block is threadedly connected to interface two, and the sealing block is rotatably sealed with the main body.

[0006] Preferably, the inner wall of the inclined annular groove is provided with a second anti-oxidation layer, and the second anti-oxidation layer is arranged in coordination with the anti-oxidation layer.

[0007] Preferably, an anti-oxidation layer three is provided in the discharge ring groove and the discharge outlet.

[0008] Preferably, the extrusion mechanism includes an extrusion groove, which is provided on the sealing block. An extrusion block is slidably engaged in the extrusion groove. A spring is installed in the extrusion groove, and the output end of the spring abuts against the extrusion block.

[0009] Preferably, sealing films are installed on both sides of the sealing block.

[0010] Preferably, the base abuts against the inner wall of the inclined annular groove, and the bottom end of the V-shaped frame is installed on the base.

[0011] Compared with the existing technology, this technical solution has at least one of the following beneficial effects:

[0012] 1. The V-shaped frame and the stable triangular structure enhance the impact resistance of the outer wall of the PE pipe, thus preventing the outer wall and antioxidant layer of the PE pipe from being damaged by impact;

[0013] 2. After the outer wall of the PE pipe is damaged, the anti-oxidation layer on the V-shaped frame can play a secondary sealing role, preventing the inner wall of the PE pipe from being directly oxidized and damaged. Moreover, when corrosive liquid drips onto the V-shaped frame, the inclined setting of the V-shaped frame prevents the corrosive liquid from staying for a long time and can be directed to the discharge ring groove for discharge, thus avoiding oxidation damage after the PE pipe is penetrated.

[0014] 3. By rotating the sealing block, the elastic block stuck in the through groove can be squeezed out through the extrusion mechanism, thereby facilitating the separation of the two PE pipes. During installation, the threaded connection between the sealing block and interface 1 and interface 2 avoids the cumbersome process of traditional multiple bolt installation.

DETAILED DESCRIPTION

[0020] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] See also Figures 1 to 4 The embodiment of the present application provides a high-strength, antioxidant PE pipe, comprising a body 1, the outer wall of the body 1 should be provided with an antioxidant layer, a plurality of inclined annular grooves 2 are provided in the body 1, adjacent inclined annular grooves 2 are symmetrically arranged, a plurality of V-shaped frames 3 are installed in the inclined annular grooves 2, the V-shaped frames 3 and the antioxidant layer 4 should abut against the inclined annular grooves 2 at both ends and should have a sealing effect, the V-shaped frame 3 is provided with an antioxidant layer 4 on the side close to the outer wall of the body 1, adjacent V-shaped frames 3 abut, a discharge annular groove 5 is provided on the body 1, the discharge annular groove 5 is connected to the lowest end of the V-shaped frame 3, and a discharge port 6 is provided at the bottom end of the discharge annular groove 5; The body 1 is equipped with interface 1 7 and interface 2 8. Both interface 1 7 and interface 2 8 are located on the higher end side of the inclined annular groove 2. Interface 1 7 is provided with a through groove 9. Interface 2 8 is equipped with an elastic card block 10. The elastic card block 10 can undergo a certain elastic bending and reset; when the elastic card block 10 is clamped in the through groove 9, interface 1 7 and interface 2 8 abut and seal; interface 1 7 is threadedly connected with a sealing block 11, and the sealing block 11 is equipped with an extrusion mechanism for squeezing the elastic card block 10 out of the through groove 9. The sealing block 11 is threadedly connected to interface 2 8, and the sealing block 11 is rotationally sealed with the body 1.

[0022] In this embodiment, when the main body 1 is impacted by an external force, the several V-shaped frames 3 in the inclined annular groove 2 can play a certain supporting role on the outer wall of the main body 1 through the triangular stable structure, and the adjacent V-shaped frames 3 abut against each other, thereby being able to transmit the external force to the adjacent V-shaped frames 3, further improving the impact resistance; when the outer wall of the main body 1 is damaged or corroded by the corrosive liquid, the anti-oxidation layer 4 on the V-shaped frame 3 close to the outside of the main body 1 can form a new protective layer to prevent the main body 1 from being completely oxidized and corroded. When the corrosive liquid penetrates the outer wall of the main body 1 and drips onto the V-shaped frame 3, the inclined setting of the V-shaped frame 3 allows the corrosive liquid to flow from it more quickly to the discharge annular groove 5 and then be discharged from the discharge port 6, thereby preventing the anti-oxidation layer 4 from being corroded and damaged by the corrosive liquid. When the PE pipe needs to be replaced, the sealing block 11 is rotated so that the extrusion mechanism on it can be inserted into the through groove 9, so that the elastic card block 10 is separated from the through groove 9, so that the interface 1 7 and the interface 2 8 can be replaced separately. When installing and connecting the new interface 1 7 and the interface 2 8, the sealing block 11 is first screwed to one side of the interface 1 7 so that when the interface 2 8 abuts against the interface 1 7, the interface 2 8 will not collide with the raised thread on the sealing block 11. After abutting, the sealing block 11 is continued to be screwed, thereby connecting the interface 1 7 and the interface 2 8 together, and the two sides of the sealing block 11 are sealed and connected to the main body 1 by a sealing rotation and sliding, so that foreign matter is not easy to enter through the sealing block 11.

[0023] In some embodiments, in order to further improve the anti-oxidation ability within the inclined annular groove 2, an anti-oxidation layer 12 is provided on the inner wall of the inclined annular groove 2. The anti-oxidation layer 12 is arranged in conjunction with the anti-oxidation layer 4 to form a new closed space for transporting liquid on the inner wall of the main body 1, thereby avoiding oxidation damage between the PE pipes.

[0024] In some embodiments, in order to prevent the PE pipe from being damaged by oxidation at the discharge ring groove 5 and the discharge port 6, an anti-oxidation layer 13 is provided in the discharge ring groove 5 and the discharge port 6.

[0025] In some embodiments, in order to squeeze the elastic block 10 out of the through slot 9, an extrusion mechanism is provided, including an extrusion slot 14. The extrusion slot 14 is provided on the sealing block 11. An extrusion block 15 is slidably engaged in the extrusion slot 14. A spring 16 is installed in the extrusion slot 14, and the output end of the spring 16 abuts against the extrusion block 15. The extrusion of the spring 16 in the extrusion slot 14 allows the extrusion block 15 to be squeezed out and squeeze the elastic block 10, causing it to bend and then be pulled out by the second interface 8. At this time, the sealing block 11 and the second interface 8 are no longer threadedly connected. The extrusion block 15 is provided with a chamfer in the rotation direction of the sealing block 11, so that after squeezing the elastic block 10 out of the through slot 9, the extrusion block 15 can slide out of the through slot 9 again.

[0026] In some embodiments, in order to achieve a sealing effect between the sealing block 11 and the body 1 , sealing films 17 are installed on both sides of the sealing block 11 .

[0027] In some embodiments, to further enhance the support capability of the V-shaped frame 3, a base 18 is provided. The base 18 abuts against the inner wall of the inclined annular groove 2, and the bottom end of the V-shaped frame 3 is mounted on the base 18. This increases the contact area between the bottom end of the V-shaped frame 3 and the body 1, preventing the V-shaped frame 3 from directly poking the body 1.
