Description

Technical Field

[0001] This utility model relates to the field of pipeline system sealing technology, specifically to push ring seals. Background Technology

[0002] This push-ring seal is used in DLB series spring tube seals. Conventional spring tube seals use a sealing ring to fix and push against the spring and spring box. However, in actual use, since the spring box is slidably sleeved on the outside of the pipe wall, the inner wall of the spring box will wear against the outer wall of the pipe during long-term repeated sliding, affecting its service life. Therefore, the maintenance frequency is high and the spring box needs to be replaced frequently. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a push ring seal, which solves the problem that existing spring tube seals lack a stable sliding support structure between the push ring and the spring box, resulting in severe wear of the spring box during use.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a push ring seal, including a ring body, with a circular insertion port and a circular fitting port respectively provided on both sides inside the ring body, and three mounting holes and a conical hole provided inside the ring body and outside the circular fitting port, the three mounting holes and the conical hole being connected and evenly distributed on the ring body.

[0005] Preferably, the outer wall of the ring body, located on the side of the circular insertion port, is provided with three pairs of arc-shaped inner grooves.

[0006] Preferably, the inner diameter of the circular socket is larger than the inner diameter of the circular fitting opening.

[0007] This utility model provides a push ring seal, which has the following advantages: Three mounting holes and a tapered hole are evenly distributed on the ring body, allowing three locating pins to be slidably inserted. The spring box can slide back and forth on one side of the push ring via the three locating pins, thus avoiding friction with the pipeline and preventing simultaneous damage to both the pipeline and the spring box. Three pairs of concave arc-shaped grooves are provided on the ring body, which helps to securely install the ring on the pipeline. Attached Figure Description

[0011] 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.

[0012] Please see Figure 1-2 This utility model provides a technical solution: a push ring seal, including a ring body 1, with a circular insertion port 5 and a circular fitting port 4 respectively provided on both sides inside the ring body 1, and three mounting holes 6 and a conical hole 2 provided inside the ring body 1 and outside the circular fitting port 4, the three mounting holes 6 and the conical hole 2 are connected, and the three mounting holes 6 and the conical hole 2 are evenly distributed on the ring body 1;

[0013] This push ring is used in conjunction with the spring box and spring, which is common technical knowledge in the DLB series spring tube seal. This design mainly improves the push ring, so there is no need to go into detail about the specific structure and usage of the spring box and spring.

[0014] Furthermore, the outer wall of the ring body 1, located on one side of the circular insertion port 5, is provided with three pairs of arc-shaped inner grooves 3.

[0015] Furthermore, the inner diameter of the circular socket 5 is larger than the inner diameter of the circular fitting opening 4.

[0016] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0017] Example: In use, mounting hole 6 and tapered hole 2 are used for sliding insertion of three positioning pins from the spring box. In traditional DLB series spring tube seals, the push ring and spring box are only connected by several springs. During the reciprocating motion of the spring box, it will rub against the pipe and cause damage. This design sets three positioning pins between the spring box and the push ring (not the focus of this design, so it will not be described in detail). The three positioning pins can slide back and forth in mounting hole 6 and tapered hole 2. The positioning pins reduce the friction between the spring box and the pipe. However, in practice, motion friction is unavoidable. This design uses the reciprocating motion of the three positioning pins in mounting hole 6 and tapered hole 2 to counteract the friction between the spring box and the pipe.

[0018] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
