Description
Technical Field
[0001] This utility model belongs to the field of PVC pipe technology, and specifically relates to a PVC pipe with a butt sealing structure. Background Technology
[0002] PVC pipes, also known as polyvinyl chloride pipes, are thermoplastic pipes polymerized from vinyl chloride monomers. They possess excellent acid, alkali, and corrosion resistance, unaffected by moisture or soil pH. Lightweight, they are easy to handle and install, significantly saving construction time and labor costs. Low production costs result in relatively inexpensive prices. Excellent water tightness is maintained regardless of whether adhesive or rubber ring connections are used. If manufactured entirely with environmentally friendly additives, PVC pipes will be non-toxic, odorless, and environmentally friendly.
[0003] In practical use of PVC pipes, multiple PVC pipes often need to be connected according to the conveying length to ensure that they can be delivered to the designated location. During the connection of two PVC pipes, sealing rings are usually installed at the joint to ensure the sealing of the joint. However, the sealing rings are not directly connected to the joint of the PVC pipes. When connecting two PVC pipes, the position of the pipes needs to be adjusted to prevent misalignment. However, this adjustment can easily cause the sealing rings to fall off, resulting in connection difficulties. Utility Model Content
[0004] The purpose of this utility model is to provide a PVC pipe with a butt sealing structure, which aims to solve the problem in the existing technology where the sealing ring is not directly connected to the end of the PVC pipe. When connecting two PVC pipes, the position of the pipes needs to be adjusted to prevent misalignment. However, this adjustment can easily cause the sealing ring to fall off, resulting in difficulty in butt connection.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a PVC pipe with a butt-sealing structure, comprising a PVC pipe body, one end of the PVC pipe body being a butt end and another end being a plug end, the inner wall of the plug end having two annular grooves, the annular grooves being connected to an annular sealing component, the end of the plug end having a threaded groove, the surface of the butt end having an annular sliding groove, the annular sliding groove having an annular slider, the surface of the annular slider being connected to a rotating block, the inner wall of the PVC pipe body being connected to an anti-pressure block, and the annular sealing component comprising a first annular sealing ring and a second annular sealing ring.
[0006] As a preferred embodiment of the PVC pipe with a butt sealing structure according to this utility model, the size of the second annular sealing ring is larger than the size of the first annular sealing ring.
[0007] As a preferred embodiment of the PVC pipe with a butt sealing structure according to this utility model, the second annular sealing ring is adapted to the size of the annular groove.
[0008] As a preferred embodiment of the PVC pipe with a butt sealing structure of the present invention, the annular sealing component can form an interference fit connection with the plug end through the annular groove.
[0009] As a preferred embodiment of the PVC pipe with a butt sealing structure of this utility model, the annular groove and the annular slider are adapted to form a "convex" shape.
[0010] As a preferred embodiment of the PVC pipe with a butt sealing structure of this utility model, the rotating block can form a rotating connection with the butt end through an annular groove and an annular slider.
[0011] As a preferred embodiment of the PVC pipe with a butt sealing structure of this utility model, the outer wall of the rotating block is provided with a thread that matches the threaded groove, and the rotating block and the threaded groove are connected by a thread.
[0012] Compared with the prior art, the beneficial effects of this utility model are: Through the cooperation between the annular groove, the annular sealing component, the first annular sealing ring, and the second annular sealing ring, the operator can press the second annular sealing ring of the annular sealing component into the annular groove when connecting PVC pipes, thereby ensuring the stability of the annular sealing component. After the connecting end and the insertion end are inserted, the first annular sealing ring can seal at the connecting end and the insertion end. At the same time, the fixation of the annular sealing component ensures that the annular sealing component will not fall off when the PVC pipe is adjusted. In addition, the two annular sealing components ensure double sealing, further improving the sealing performance.
[0013] Through the cooperation between the threaded groove, the annular slide, the annular slider and the rotating block, the operator can rotate the rotating block to drive the annular slider to rotate inside the annular slide. Then, the rotating block is screwed into the threaded groove, which facilitates the connection of two PVC pipe bodies, thereby improving the convenience of installation. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1-6 The present invention provides the following technical solution: a PVC pipe with a butt sealing structure, comprising a PVC pipe body 1, one end of the PVC pipe body 1 being a butt end 2, and another end of the PVC pipe body 1 being a plug end 3. The inner wall of the plug end 3 is provided with two annular grooves 4, and an annular sealing component 5 is connected inside the annular grooves 4. The end of the plug end 3 is provided with a threaded groove 6. The surface of the butt end 2 is provided with an annular sliding groove 7, and an annular slider 8 is provided inside the annular sliding groove 7. A rotating block 9 is connected to the surface of the annular slider 8. An anti-pressure block 10 is connected to the inner wall of the PVC pipe body 1. The annular sealing component 5 includes a first annular sealing ring 51 and a second annular sealing ring 52. The size of the second annular sealing ring 52 is larger than the size of the first annular sealing ring 51. The size of the second annular sealing ring 52 is adapted to the size of the annular groove 4. The annular sealing component 5 can form an interference fit connection with the plug end 3 through the annular groove 4.
[0018] In actual use, when an operator docks PVC pipes, the second annular sealing ring 52 of the annular sealing assembly 5 is interference-fitted and clamped into the annular groove 4, thereby ensuring the stability of the annular sealing assembly 5. Then, after the butt end 2 is inserted into the socket end 3, the first annular sealing ring 51 can seal the joint between the butt end 2 and the socket end 3 while the annular sealing assembly 5 is fixed. The annular sealing assembly 5 is made of hydrogenated nitrile butadiene rubber, which has excellent corrosion resistance, tear resistance and compression deformation resistance, as well as good ozone resistance, sunlight resistance and weather resistance. Furthermore, when the PVC pipe is adjusted, the annular sealing assembly 5 will not fall off. It is worth noting that the use of two annular sealing assemblies 5 ensures double sealing, further improving the sealing performance of the butt joint.
[0019] Preferably: the annular chute 7 and the annular sliding block 8 are adapted to each other in a "convex" shape. The rotating block 9 can form a rotational connection with the butt end 2 through the annular chute 7 and the annular sliding block 8. The outer wall of the rotating block 9 is provided with threads adapted to the thread groove 6, and the rotating block 9 is in threaded connection with the thread groove 6.
[0020] In actual use, an operator can rotate the rotating block 9 to drive the annular sliding block 8 to rotate inside the annular chute 7. Since the annular sliding block 8 and the annular chute 7 are in a "convex" shape, it is ensured that the annular sliding block 8 will not separate from the annular chute 7, which ensures the stability of rotation. Meanwhile, the rotating block 9 is connected to the annular sliding block 8, and rotating the rotating block 9 can drive the annular sliding block 8 to rotate inside the annular chute 7, which makes the operation more convenient. Furthermore, the rotating block 9 is screwed into the thread groove 6, thereby facilitating the butt joint of two PVC pipe bodies 1, which improves the convenience of installation.
[0021] Working principle: When two PVC pipes are butted, the second annular sealing ring 52 of the annular sealing assembly 5 is interference-fitted and clamped into the annular groove 4. Then, the butt end 2 of one PVC pipe is connected to the socket end 3 of the other PVC pipe. Then an operator rotates the rotating block 9 to drive the annular sliding block 8 to rotate inside the annular chute 7. Next, the rotating block 9 is screwed into the thread groove 6, thereby facilitating the butt joint of two PVC pipe bodies 1. With the rotation of the rotating block 9, the butt end 2 and the socket end 3 approach each other, so that the first annular sealing ring 51 of the annular sealing assembly 5 seals the joint between the butt end 2 and the socket end 3 while the annular sealing assembly 5 is fixed. This ensures that the annular sealing assembly 5 does not move when PVC pipes are butted, and also ensures that the annular sealing assembly 5 does not fall off when the PVC pipes are adjusted. Finally, two annular sealing assemblies 5 provide double sealing, which further improves the sealing performance.
[0022] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
