Description

Technical Field

[0001] This utility model relates to the field of sealing ring technology, and in particular to a leak-proof sealing ring. Background Technology

[0002] A sealing ring is a circular elastic sealing device, mainly used for static sealing and reciprocating motion sealing. Currently, in pipe connections, sealing rings are mainly installed between the end faces of two pipes to prevent leakage when fluid flows between the two pipes.

[0003] Existing sealing rings are mainly circular ring structures that maintain a tight fit with the pipe end face through compression. However, existing sealing rings are prone to deformation during use due to radial compression, which reduces the sealing effect of the sealing ring on the pipe end face and easily causes side leakage. To address this, we propose a leak-proof sealing ring. Utility Model Content

[0004] The purpose of this invention is to provide a leak-proof sealing ring to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof sealing ring, comprising:

[0006] Highly elastic ring;

[0007] An upper sealing ring is fixedly connected to the upper surface of a highly elastic ring body;

[0008] A lower sealing ring is fixedly connected to the lower surface of a highly elastic ring body.

[0009] The reinforcing rib is fixedly inserted into the upper and lower sealing rings.

[0010] Preferably, the upper sealing ring and the lower sealing ring are annular rings with the same inner diameter, the inner diameter of the reinforcing rib is larger than the inner diameter of the upper sealing ring and the lower sealing ring, and the outer diameter of the reinforcing rib is smaller than the outer diameter of the upper sealing ring and the lower sealing ring.

[0011] Preferably, the top of the outer peripheral wall of the upper sealing ring is provided with an integrally formed first lip, which extends obliquely upward.

[0012] Preferably, the top of the inner peripheral wall of the upper sealing ring is provided with an integrally formed second lip, the upper surface of the second lip is a horizontal plane, and the lower surface of the second lip is a slope.

[0013] Preferably, the reinforcing rib is fixedly connected to both the upper and lower sides, and the reinforcing ribs located on the same side of the reinforcing rib are two ribs that are spaced apart from each other.

[0014] Preferably, the interior of the highly elastic ring is provided with a weight-reducing through hole, the weight-reducing through hole is annular, and the cross-section of the weight-reducing through hole is circular.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This invention incorporates a highly elastic ring between the upper and lower sealing rings. The high elasticity of this ring enhances the elasticity of the sealing ring, improving the tightness of the connection between the upper and lower sealing rings and the pipe end face. Furthermore, reinforcing ribs within the upper and lower sealing rings provide radial shaping, increasing their stability under radial force. This ensures a tight fit between the end faces of the upper and lower sealing rings and the pipe end face, thereby improving the sealing performance of the pipe connection and enhancing the prevention of side leakage.

[0022] 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.

[0023] This utility model provides, for example Figures 1-2The leak-proof sealing ring shown includes a highly elastic ring 100, an upper sealing ring 101, and a lower sealing ring 102. The upper sealing ring 101 is fixedly connected to the upper surface of the highly elastic ring 100, and the lower sealing ring 102 is fixedly connected to the lower surface of the highly elastic ring 100. A reinforcing rib 106 is fixedly inserted into the upper sealing ring 101 and the lower sealing ring 102. In this embodiment, the lower sealing ring 102 is inserted into a pre-set annular positioning groove on the end face of a pipe for positioning, so that when the end face of another pipe is connected, it contacts the side of the upper sealing ring 101 away from the lower sealing ring 102. Through pressure, the highly elastic ring 100 undergoes elastic deformation. At the same time, the end faces of the upper sealing ring 101 and the lower sealing ring 102 are tightly fitted with the end faces of the two pipes, respectively. During this process, the elastic reaction generated by the deformation of the highly elastic ring 100 provides a pushing force to the upper sealing ring 101 and the lower sealing ring 102. The force exerted by the upper sealing ring 101 and the lower sealing ring 102 on the pipe end face creates a thrust, which further maintains the tightness of the fit between the upper sealing ring 101 and the lower sealing ring 102 and the pipe end face, thereby achieving an annular seal at the pipe joint. In addition, reinforcing ribs 106 are fixedly installed inside the upper sealing ring 101 and the lower sealing ring 102. The reinforcing ribs 106 are circular and made of rigid material, which can provide stable anti-deformation in the radial direction. This prevents large deformation when the upper sealing ring 101 and the lower sealing ring 102 are subjected to radial torque, thus ensuring that the end faces of the upper sealing ring 101 and the lower sealing ring 102 maintain a stable fit with the pipe end face. This avoids side leakage at the pipe joint due to radial deformation of the upper sealing ring 101 and the lower sealing ring 102, thereby improving the sealing performance of the pipe joint.

[0024] Furthermore, the upper sealing ring 101 and the lower sealing ring 102 are annular rings with the same inner diameter. The inner diameter of the reinforcing rib 106 is larger than the inner diameter of the upper sealing ring 101 and the lower sealing ring 102, and the outer diameter of the reinforcing rib 106 is smaller than the outer diameter of the upper sealing ring 101 and the lower sealing ring 102. The inner and outer diameters of the reinforcing rib 106 are larger and smaller than the inner and outer diameters of the upper sealing ring 101 and the lower sealing ring 102, respectively. This allows the dimensions of the reinforcing rib 106 to meet the installation requirements inside the upper sealing ring 101 and the lower sealing ring 102, thereby positioning the reinforcing rib 106 in the middle of the upper sealing ring 101 and the lower sealing ring 102. This provides a better stabilizing effect for the upper sealing ring 101 and the lower sealing ring 102. Ribs 107 are fixedly connected to both the upper and lower sides of the reinforcing rib 106. Ribs 107 are located on the same side of the reinforcing rib 106. 107 consists of two ribs spaced apart, one inside and one outside. The ribs 107 ensure a stable installation of the reinforcing ribs 106 within the upper sealing ring 101 and lower sealing ring 102. In actual manufacturing, the reinforcing ribs 106 can be cast into the mold at the corresponding position, and then formed by hot-melt injection molding to enclose the upper sealing ring 101 and lower sealing ring 102 with the reinforcing ribs 106. The ribs 107 not only further enhance the shaping effect of the reinforcing ribs 106 on the upper sealing ring 101 and lower sealing ring 102 and enhance the radial stability of the upper sealing ring 101 and lower sealing ring 102, but also increase the bonding area with the interior of the upper sealing ring 101 and lower sealing ring 102, improving the stability of the reinforcing ribs 106 within the upper sealing ring 101 and lower sealing ring 102.

[0025] Furthermore, the top of the outer peripheral wall of the upper sealing ring 101 is provided with an integrally formed first lip 103, which extends obliquely upward; the top of the inner peripheral wall of the upper sealing ring 101 is provided with an integrally formed second lip 104, the upper surface of which is horizontal and the lower surface of which is inclined. The first lip 103 is provided so that it can undergo outward elastic deformation when it contacts and is squeezed against the pipe end face, thereby increasing the contact area with the pipe end face, and in conjunction with the elasticity of the first lip 103 itself... The upper sealing ring 101 maintains a tight fit with the pipe end face, thus enhancing the sealing effect. The second lip 104, while the upper sealing ring 101 is in tight fit with the pipe end face, allows the pressure of the fluid flowing upwards from the lower sealing ring 102 to act on the inclined surface of the second lip 104, generating a thrust. This prevents fluid from leaking from the contact point between the upper sealing ring 101 and the pipe end face, thus enhancing the sealing effect.

[0026] In addition, the interior of the high elastic ring 100 is provided with a weight-reducing through hole 105. The weight-reducing through hole 105 is annular and its cross-section is circular. The weight-reducing through hole 105 not only reduces the material used in the high elastic ring 100, but also enhances the elastic strength of the high elastic ring 100.
