[0034] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0035] like Figure 1-Figure 2As shown, the embodiment of the present application discloses a PCIP anti-detachment self-checking and repairing polyolefin anti-seepage tube, comprising: a first tube body 1, a second tube body 2 and various structures formed on the first tube body 1 and the second tube body 2, such as: a first port 10, a second port 11, a socket 3, a socket 4, a first rubber ring 5, a second rubber ring 6, a clamping ring 7, a buckle 8, and a groove 9. Among them:
[0036] The end of the first tube body 1 is provided with a first port 10 , which constitutes a socket 3 for mutually plugging the first tube body 1 and the second tube body 2 . The inner diameter of the socket 3 roughly matches the outer diameter of the end of the second tube body 2 .
[0037] The end of the second tube body 2 is provided with a second port 11, which constitutes a socket 4 for mutually plugging the first tube body 1 and the second tube body 2. The outer diameter of the socket 4 roughly matches the inner diameter of the socket 3, so that the socket 4 can be plugged into the socket 3.
[0038] In order to prevent the first tube body 1 and the second tube body 2 which are plugged together from being separated, a clamping ring 7 is provided on the outer circumferential surface of the socket 4, and correspondingly, a buckle 8 is provided on the inner circumferential surface of the socket 3. When the first tube body 1 and the second tube body 2 are plugged together at the socket 3 and the socket 4, the buckle 8 is inserted into the clamping ring 7, thereby playing a role in preventing separation.
[0039] In order to achieve the function of sealing and preventing leakage, a groove 9 is provided on the outer circumferential surface of the socket 4, and accordingly, the first rubber ring 5 is installed in the groove 9. When the socket 3 and the socket 4 are plugged together, the two opposite sides of the first rubber ring 5 are respectively abutted between the socket 3 and the socket 4, thereby forming a sealing barrier for the gap formed between the socket 3 and the socket 4, preventing the fluid from leaking out from the connection of the pipeline, and improving the sealing of the pipeline interface.
[0040] In a preferred embodiment, in order to further improve the sealing performance of the pipe connection (that is, the socket 3 and the socket 4), a plurality of grooves 9 are provided. Accordingly, in addition to installing the first rubber ring 5 in the groove 9, one or more second rubber rings 6 can be selectively installed according to the use conditions. By arranging more than one rubber ring, the sealing performance of the pipe connection can be further improved.
[0041] See also Figure 2 , Figure 2The figure shows a situation where two rubber rings are installed in the groove 9, wherein the first rubber ring 5 is arranged in the groove 9 adjacent to the first port 10, and the second rubber ring 6 is arranged in the groove 9 adjacent to the second port 10. On the other hand, the second rubber ring 6 is located between the clamp ring 7 and the first rubber ring 5. Similarly, the second rubber ring 6 is tightly fitted between the socket 3 and the socket 4, and the addition of the second rubber ring 6 further improves the impermeability and sealing of the pipe interface.
[0042] Continue to see Figure 2 In an optional embodiment, there is at least one vacant groove 9 between the first rubber ring 5 and the second rubber ring 6, or there is at least one vacant groove 9 between the second rubber ring 6 and the clamping ring 7. Accordingly, a hole (not shown in the figure) is opened on the pipe wall of the socket 3 corresponding to the vacant groove 9. When the seals of the first rubber ring 5 and the second rubber ring 6 fail, the relevant sealing material can be injected through the hole to fill between the socket 3 and the socket 4, thereby realizing the functions of sealing repair and sealing compensation.
[0043] From the above structural introduction, it can be seen that the PCIP anti-slip self-checking and repairing polyolefin anti-seepage pipe disclosed in this application,
[0044] When the socket 4 is inserted into the socket 3, the clamp ring 7 and the buckle 8 cooperate with each other to achieve the connection between the first tube body 1 and the second tube body 2. The first rubber ring 5 arranged between the socket 4 and the socket 3 makes the socket 3 and the socket 4 tightly connected, thereby improving the sealing and impermeability between the socket 3 and the socket 4. When the first rubber ring 5 is worn out due to long-term use, the second rubber ring 6 can compensate for the loss of the sealing of the pipeline interface caused by the loss of the first rubber ring 5, thereby avoiding the situation that the pipeline interface cannot work normally due to the loss of the first rubber ring 5. When the second rubber ring 6 is damaged due to wear or other reasons, the relevant sealing material can be injected through the hole to fill between the socket 3 and the socket 4, thereby achieving self-repair, self-compensation, and re-sealing. That is to say, in the case where both the first rubber ring 5 and the second rubber ring 6 are worn out, the sealing of the pipeline interface can also be unaffected, thereby extending the service life of the polyolefin pipe.
[0045] In a specific embodiment,
[0046] The first port 10 provided on the first pipe body 1 is formed by expanding the pipe body portion of the first pipe body 1 outwardly, and the outer diameter of the socket 3 formed by the first port 10 is larger than the outer diameter of the pipe body portion of the first pipe body 1. Generally speaking, the socket 3 is annular, and the inner diameter of the socket 3 matches the outer diameter of the connected pipe. The free end of the socket 3 is provided with a buckle 8 extending inwardly, and the buckle 8 has a convex portion so as to be clamped in the clamping ring 7 or the groove 9.
[0047] The second port 11 provided on the second tube body 2 is formed by extending the tube body portion of the second tube body 2, that is, the outer diameter of the socket 4 formed by the second port 11 is substantially the same as the outer diameter of the tube body portion of the second tube body 2, except that the groove 9 and the retaining ring 7 at the socket 4 protrude outward. It can be basically known from this that the outer diameter of the second port 11 is substantially the same as the inner diameter of the first port 10.
[0048] In this embodiment, the lengths of the socket 4 and the socket 3 are substantially the same, the socket 4 enters into the socket 3, the outer wall of the socket 4 contacts the inner wall of the socket 3, and the socket 4 moves along the axial direction of the first port 10 of the socket 3. At this time, the buckle 8 enters into the retaining ring 7, so that the socket 4 and the socket 3 are fixedly connected.
[0049] From the above embodiments, it can be seen that
[0050] The first rubber ring 5 is arranged in the groove 9 at the free end of the socket 4. The first rubber ring 5 is usually a solid structure. The shape of the first rubber ring 5 is adapted to the groove 9, so that the first rubber ring 5 is fixed in the groove 9, thereby improving the stability of the first rubber ring 5 in the groove 9. The first rubber ring 5 surrounds the circumferential surface of the socket 4 to form a sealing ring. The first rubber ring 5 is usually made of corrosion-resistant and elastic materials, such as rubber or plastic. In the present application, preferably, the first rubber ring 5 is made of rubber. When the socket 4 is inserted into the socket 3, the elastic first rubber ring 5 will be squeezed to generate a certain tension. This tension can help fix the socket 4 and to a certain extent can help prevent it from sliding or falling off from the socket 3, so that the socket 3 and the socket 4 are tightly connected.
[0051] The second rubber ring 6 is located between the clamp ring 7 and the first rubber ring 5. The second rubber ring 6 plays an auxiliary sealing role, so the second rubber ring 6 can be a solid structure or a hollow structure of other shapes or have an expansion function. Similarly, the shape of the second rubber ring 6 is adapted to the groove 9, so that the second rubber ring 6 is fixed in the groove 9, thereby improving the stability of the second rubber ring 6 in the groove 9. The second rubber ring 6 surrounds the circumferential surface of the socket 4 and also forms a sealing ring, which fits tightly between the socket 3 and the socket 4, further improving the sealing and impermeability of the pipeline interface. During use, when the first rubber ring 5 is worn out due to long-term use, the liquid will enter the second rubber ring 6 through the first rubber ring 5. The volume of the second rubber ring 6 will expand after encountering water. The expanded second rubber ring 6 will further fit tightly between the socket 3 and the socket 4, compensating for the loss of sealing of the pipeline caused by the loss of the first rubber ring 5. When the second rubber ring 6 is damaged due to wear or other reasons, the second rubber ring 6 absorbs water and expands to achieve a certain compensatory seal, so that the sealing performance of the pipeline is not affected.
[0052] To summarize, when in use, opposite forces are applied to the first tube body 1 and the second tube body 2 at the same time, so that the bell-and-spigot joint 4 arranged on the second tube body 2 enters into the bell-and-spigot socket 3 arranged on the first tube body 1, and the outer wall of the bell-and-spigot joint 4 contacts the inner wall of the bell-and-spigot socket 3, and the bell-and-spigot socket 4 moves axially along the bell-and-spigot socket 3 toward the first port 10. When the free end of the bell-and-spigot joint 4 contacts the end of the first port 10, the bell-and-spigot joint 4 stops moving. At this time, the buckle 8 enters into the retaining ring 7, so that the bell-and-spigot joint 4 and the bell-and-spigot socket 3 are fixedly connected. In addition, the first rubber ring 5 is arranged between the bell-and-spigot socket 4 and the bell-and-spigot socket 3 to make the bell-and-spigot socket 3 and the bell-and-spigot socket 4 tightly connected, thereby improving the sealing and impermeability between the bell-and-spigot socket 3 and the bell-and-spigot socket 4. When the first rubber ring 5 is worn out due to long-term use, the liquid will enter the second rubber ring 6 through the first rubber ring 5. The volume of the second rubber ring 6 will expand after encountering water. The expanded second rubber ring 6 will further fit tightly between the bell-and-spigot socket 3 and the bell-and-spigot socket 4, compensating for the loss of the sealing of the pipeline interface caused by the loss of the first rubber ring 5, thereby avoiding the situation where the pipeline interface cannot work normally due to the loss of the first rubber ring 5. When the second rubber ring 6 is damaged due to wear or other reasons, sealing material can be injected from the hole of the bell-and-spigot socket 3 to re-form a new sealing barrier, so that even if both the first rubber ring 5 and the second rubber ring 6 are worn out, the sealing of the pipeline interface will not be affected.

Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
