Technical Field
[0001] The utility model relates to the technical field of PVC pipes, in particular to an insulating PVC pipe. Background Art
[0002] PVC pipes are pipes made of polyvinyl chloride resin, which have excellent chemical corrosion resistance and insulation properties. This material is widely used due to its excellent chemical corrosion resistance and insulation properties, and other components are added to enhance its heat resistance, toughness and ductility.
[0003] However, when the existing PVC pipes are in use, two PVC pipes are usually connected by glue. However, during the long-term use of the PVC pipes, the glue at the joints of the PVC pipes is prone to aging and falling off, and cracks will occur at the joints of the PVC pipes, which will have a certain impact on the insulation performance of the PVC pipes. Therefore, an insulating PVC pipe is provided. Summary of the Utility Model
[0004] The main purpose of the utility model is to provide an insulating PVC pipe. By setting a fixing sleeve, a threaded sleeve, a limiting block, a ring sleeve A, a ring sleeve B, a rubber sleeve, a ring block, a ring groove and a rubber ring, the utility model solves the problem that the insulation performance at the joints of PVC pipe A and PVC pipe B is poor when the existing PVC pipes are in use.
[0005] The technical solution adopted by the utility model to solve its technical problems is an insulating PVC pipe, which includes PVC pipe A and PVC pipe B. A fixing sleeve fixed at the joint of PVC pipe A and PVC pipe B is sleeved outside the PVC pipe B. A ring sleeve B for limiting the fixing sleeve is integrally formed outside the PVC pipe B. A ring sleeve A for limiting the fixing sleeve is integrally formed outside the PVC pipe A. A limiting block in contact with the ring sleeve A is integrally formed outside the fixing sleeve. A threaded sleeve for fixing the limiting block is threadedly connected outside the fixing sleeve. A ring block for connecting with the PVC pipe A is integrally formed at the end of the PVC pipe B. A ring groove for the ring block to enter the inside of the PVC pipe A is formed at the end of the PVC pipe A. Insulation layers A for improving the insulation performance are arranged on the inner sides of the PVC pipe A and the PVC pipe B. An insulation layer B is arranged inside the fixing sleeve, and an insulation layer C is arranged on one side of the insulation layer B. An insulation layer D for improving the insulation performance at the joint of the PVC pipe A and the PVC pipe B is arranged outside the insulation layer C. A rubber ring for improving the sealing line at the joint of the PVC pipe A and the PVC pipe B is bonded at the end of the PVC pipe A. Rubber sleeves for improving the sealing performance with the fixing sleeve are bonded outside the ring sleeve A and the ring sleeve B.
[0006] By adopting the above-mentioned technical solution, when connecting PVC pipe A and PVC pipe B, first place the ring block on PVC pipe B into the ring groove opened on PVC pipe A. The rubber ring on PVC pipe A improves the sealing performance between PVC pipe A and PVC pipe B. Then, pull the fixing sleeve to move outside PVC pipe B. Subsequently, the inner side of the fixing sleeve is connected to the ring sleeve B outside PVC pipe B. Then, the limiting block at one end of the fixing sleeve moves to the outside of the ring sleeve A outside PVC pipe A, so that the fixing sleeve moves to the joint of PVC pipe A and PVC pipe B. Then, rotate the threaded sleeve outside the fixing sleeve. The threaded sleeve moves through the threaded grooves opened on the surfaces of the fixing sleeve and the limiting block, so that the threaded sleeve moves to the outside of the limiting block. The limiting block is tightly connected to the ring sleeve A outside PVC pipe A, so that the fixing sleeve is fixed at the joint of PVC pipe A and PVC pipe B. The rubber sleeves outside the ring sleeve A and the ring sleeve B increase the sealing line with the fixing sleeve, thereby improving the sealing performance at the joint of PVC pipe A and PVC pipe B;
[0007] The insulating layer B inside the fixing sleeve is made of PE plastic particles. PE plastic particles have excellent insulation resistance performance. The insulating layer C outside the insulating layer B is made of mica. Mica has very excellent insulation performance and an extremely high volume resistivity. At the same time, the insulating layer D outside the insulating layer C is made of ethylene-propylene rubber and has good insulation performance, thereby improving the insulation performance at the joint of PVC pipe A and PVC pipe B;
[0008] The insulating layer A inside PVC pipe A and PVC pipe B and the insulating layer C inside the fixing sleeve are both made of mica, improving the insulation performance of PVC pipe A and PVC pipe B.
[0009] Specifically, a rubber sheet for improving the sealing performance between the ring block and the ring groove is fixed by screws outside the ring block.
[0010] By adopting the above-mentioned technical solution, when the ring block enters the inside of the ring groove, the rubber sheet outside the ring block is tightly connected to the inner side of the ring groove, thereby increasing the sealing performance between the ring block and the ring groove.
[0011] Specifically, the inner size of the ring groove matches the outer size of the ring block.
[0012] By adopting the above-mentioned technical solution, when the ring block on PVC pipe B enters the ring groove opened on PVC pipe A, the inner side of the ring groove matches the outside of the ring block, facilitating the ring block to enter the inside of the ring groove.
[0013] Specifically, convex grain blocks for making the rotation of the threaded sleeve stable are arranged outside the threaded sleeve.
[0014] By adopting the above-mentioned technical solution, the convex grain blocks arranged outside the threaded sleeve increase the friction force on the surface of the threaded sleeve, facilitating the rotation treatment of the threaded sleeve.
[0015] Specifically, the inner size of the fixing sleeve matches the outer sizes of sleeve A and sleeve B.
[0016] By adopting the above technical solution, when the fixing sleeve moves outside PVC pipe A and PVC pipe B, the outer sizes of sleeve A and sleeve B both match the inner side of the fixing sleeve, facilitating the movement of the fixing sleeve to the outside of sleeve A and sleeve B.

Subsequently, the inner side of the fixing sleeve is connected to sleeve B outside PVC pipe B. Then, the limit block at one end of the fixing sleeve moves to the outside of sleeve A outside PVC pipe A, causing the fixing sleeve to move to the joint of PVC pipe A and PVC pipe B. Then, rotate the threaded sleeve outside the fixing sleeve. The threaded sleeve moves through the threaded grooves opened on the surfaces of the fixing sleeve and the limit block, causing the threaded sleeve to move to the outside of the limit block. The limit block is tightly connected to sleeve A outside PVC pipe A, fixing the fixing sleeve at the joint of PVC pipe A and PVC pipe B. The rubber sleeves outside sleeve A and sleeve B increase the sealing line with the fixing sleeve, thereby improving the sealing performance at the joint of PVC pipe A and PVC pipe B.

[0025] In order to improve the insulation performance at the joint of PVC pipe A1 and PVC pipe B2, as an embodiment of the present utility model, as Figure 1 、 Figure 2 shown, an insulating PVC pipe described in the present utility model includes PVC pipe A1 and PVC pipe B2. A fixing sleeve 13 fixed at the joint of PVC pipe A1 and PVC pipe B2 is sleeved outside the PVC pipe B2. An annular sleeve B9 for limiting the fixing sleeve 13 is integrally formed outside the PVC pipe B2. An annular sleeve A4 for limiting the fixing sleeve 13 is integrally formed outside the PVC pipe A1.

A threaded sleeve 10 for fixing the limiting block 17 is threadedly connected to the outside of the fixing sleeve 13. A ring block 7 connected to the PVC pipe A1 is integrally formed at the end of the PVC pipe B2. A ring groove 6 for the ring block 7 to enter the inside of the PVC pipe A1 is provided at the end of the PVC pipe A1.

A rubber ring 5 for improving the sealing performance at the joint of the PVC pipe A1 and the PVC pipe B2 is bonded to the end of the PVC pipe A1. Rubber sleeves 3 for improving the sealing performance with the fixing sleeve 13 are bonded to the outside of the annular sleeve A4 and the annular sleeve B9.
[0026] When in use, when the PVC pipe A1 and the PVC pipe B2 are connected, first put the ring block 7 on the PVC pipe B2 into the ring groove 6 opened on the PVC pipe A1, and the rubber ring 5 on the PVC pipe A1 improves the sealing between the PVC pipe A1 and the PVC pipe B2. Then pull the fixing sleeve 13 to move outside the PVC pipe B2, and then the inner side of the fixing sleeve 13 is connected with the ring sleeve B9 outside the PVC pipe B2. Then, the limit block 17 at one end of the fixing sleeve 13 is moved to the outside of the ring sleeve A4 outside the PVC pipe A1, so that the fixing sleeve 13 moves to the PVC pipe A1 and The joint of PVC pipe B2 is then located. The threaded sleeve 10 outside the fixing sleeve 13 is rotated. The threaded sleeve 10 moves through the threaded grooves on the surfaces of the fixing sleeve 13 and the limit block 17, so that the threaded sleeve 10 moves to the outside of the limit block 17. The limit block 17 is tightly connected to the ring sleeve A4 outside the PVC pipe A1, so that the fixing sleeve 13 is fixed at the joint of PVC pipe A1 and PVC pipe B2. The rubber sleeve 3 outside the ring sleeve A4 and the ring sleeve B9 increases the sealing line between the fixing sleeve 13, thereby improving the sealing of the joint of PVC pipe A1 and PVC pipe B2.
[0027] The insulating layer B14 within the fixing sleeve 13 is made of PE plastic particles, which have excellent insulation resistance performance. The insulating layer C15 outside the insulating layer B14 is made of mica, which has very excellent insulation performance and extremely high volume resistivity. At the same time, the insulating layer D16 outside the insulating layer C15 is made of ethylene propylene rubber, which has good insulation performance, thereby improving the insulation performance of the joint between the PVC pipe A1 and the PVC pipe B2.
[0028] The insulating layer A11 inside the PVC pipe A1 and the PVC pipe B2 and the insulating layer C15 inside the fixing sleeve 13 are both made of mica, which improves the insulation performance of the PVC pipe A1 and the PVC pipe B2.
[0029] In order to increase the sealing between the ring block 7 and the ring groove 6, for example, Figure 1 As shown, the present invention further includes a rubber sheet 8 fixed with screws on the outside of the ring block 7 to improve the sealing performance between the ring block 7 and the ring groove 6.
[0030] During use, when the ring block 7 enters the annular groove 6 , the rubber sheet 8 on the outside of the ring block 7 is tightly connected to the inside of the annular groove 6 , thereby increasing the sealing between the ring block 7 and the annular groove 6 .
[0031] In order to facilitate the ring block 7 to enter the ring groove 6, for example, Figure 1 As shown, the present invention also includes that the inner size of the annular groove 6 is consistent with the outer size of the ring block 7.
