Description

Technical Field

[0001] This utility model relates to the technical field of copper inserts for preventing leakage, and particularly to a copper insert for preventing leakage. Background Technology

[0002] In many scenarios of modern industrial production and daily life, systems involving fluid transportation are extremely common, from water supply and drainage pipes inside buildings to various liquid and gas transmission pipelines in chemical production. In these systems, copper inserts are widely used as key components to achieve convenient and reliable connections between pipes and to adapt to different usage needs. Copper inserts are usually used for connection parts of non-metallic pipes such as plastic pipes. With their good mechanical properties, wear resistance, and compatibility with materials such as plastics, they can achieve stable and detachable connections between different pipe materials. For example, in the water supply and drainage system of home decoration, plastic pipes are favored for their advantages such as light weight and corrosion resistance. However, in order to facilitate the installation and later maintenance of pipes, copper inserts are often used for threaded connections.

[0003] The applicant discovered a Chinese patent, "A Copper Inlay Structure for Preventing Leakage," with publication number CN205606019U. This patent primarily addresses the issue that when plastic is injected into the axial groove on the inner surface of the hole, the plastic tends to shrink radially. The inner wall of the axial groove prevents this shrinkage, allowing the plastic to adhere more tightly to the copper component, thus achieving a better water-sealing effect. However, this patent's single-groove structure lacks a dustproof and impurity filtration mechanism. In actual use, external particles and debris may enter the groove, damaging the bonding surface between the plastic and copper and accelerating seal failure. Dustproof rings and spiral guide grooves can effectively intercept solid particles and prevent impurities from abrading the sealing parts. Therefore, we propose a copper insert for preventing leakage. Utility Model Content

[0004] The purpose of this invention is to provide a copper insert that prevents leakage, thereby solving the problem that the single groove structure mentioned in the background art lacks a dustproof and impurity filtration mechanism. In actual use, external particles and debris may enter the groove, which will damage the bonding surface between the plastic and the copper and accelerate the failure of the seal. The dustproof ring and spiral guide groove can effectively intercept solid particles and avoid the problem of impurities wearing off the sealing parts.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a copper insert for preventing leakage, comprising a copper insert body, wherein an anti-leakage component is provided on the outside of the copper insert body, the anti-leakage component comprising a main sealing ring, a secondary sealing ring and a dustproof ring, a main sealing groove is provided at the lower part of the outer wall of the copper insert body, the main sealing ring is disposed inside the main sealing groove, and a secondary sealing groove is provided at the middle of the outer wall of the copper insert body.

[0006] As a preferred embodiment, the secondary sealing ring is disposed inside the secondary sealing groove, and a dustproof groove is provided on the upper part of the outer wall of the copper insert body, with the dustproof ring disposed inside the dustproof groove.

[0008] As a preferred embodiment, another set of spiral guide grooves is provided on the outer wall of the copper insert body and between the secondary sealing ring and the dustproof ring. The secondary sealing groove is located above the main sealing groove, and the dustproof groove is located above the secondary sealing groove.

[0009] As a preferred embodiment, the bottom of the copper insert body is provided with a reinforcing component, the reinforcing component including a cross-shaped anti-torsion boss, and four sets of the cross-shaped anti-torsion boss are provided, the four sets of the cross-shaped anti-torsion boss are circumferentially distributed and fixedly installed on the bottom surface of the copper insert body.

[0010] As a preferred embodiment, each of the four sets of cross-shaped anti-torsion bosses has an exhaust hole at its bottom, which is located in the middle of the bottom of the cross-shaped anti-torsion boss. The bottom of the copper insert body has four sets of radial guide grooves, which are respectively located between adjacent cross-shaped anti-torsion bosses.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the design of the anti-leakage components, the main sealing ring and the secondary sealing ring are tightly fitted with the main sealing groove and the secondary sealing groove respectively, which can form a double sealing barrier to effectively resist the pressure of the medium.

[0020] 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.

[0021] Please see the appendix Figure 1 - Appendix Figure 4A leak-proof copper insert includes a copper insert body 1, an anti-leakage component 2 on the outside of the copper insert body 1, the anti-leakage component 2 including a main sealing ring 205, a secondary sealing ring 206, and a dustproof ring 207. A main sealing groove 201 is formed at the lower part of the outer wall of the copper insert body 1, and the main sealing ring 205 is disposed inside the main sealing groove 201. A secondary sealing groove 202 is formed at the middle of the outer wall of the copper insert body 1, and the secondary sealing ring 206 is disposed inside the secondary sealing groove 202. A dustproof groove 203 is formed at the upper part of the outer wall of the copper insert body 1, and the dustproof ring... 207 is located inside the dustproof groove 203. The distance between the main sealing groove 201 and the secondary sealing groove 202 is 10 mm, and the distance between the secondary sealing groove 202 and the dustproof groove 203 is also 10 mm. A set of spiral guide grooves 204 is opened on the outer wall of the copper insert body 1 between the main sealing ring 205 and the secondary sealing ring 206. Another set of spiral guide grooves 204 is opened on the outer wall of the copper insert body 1 between the secondary sealing ring 206 and the dustproof ring 207. The secondary sealing groove 202 is located above the main sealing groove 201, and the dustproof groove 203 is located above the secondary sealing groove 202.

[0022] The function of the spiral guide groove 204 is that when the medium leaks from the main sealing ring 205, it needs to spiral upward along the spiral guide groove 204 to reach the secondary sealing ring 206. This can increase the path length and reduce the leakage rate. The spiral structure causes the medium flow to generate turbulence, which consumes energy and separates any particulate impurities that may be carried. The buffer area formed between the main sealing ring 205 and the secondary sealing groove 202 can prevent the sealing ring from being squeezed out due to sudden pressure changes.

[0023] Specifically, through the set anti-leakage component 2, the main sealing ring 205 and the main sealing groove 201, and the secondary sealing ring 206 and the secondary sealing groove 202 are tightly fitted to form a double sealing barrier to resist the pressure of the medium. The dustproof ring 207 is installed in the corresponding groove to form an external impurity interception layer to avoid wear of the sealing ring. Two sets of spiral guide grooves 204 are distributed between the sealing components to achieve impurity separation and pressure balance by extending the medium penetration path. Under the synergistic effect of each component, the sealing performance and structural stability of the copper insert body 1 are significantly improved, effectively reducing the risk of leakage and adapting to complex working conditions such as high pressure, high corrosion, and strong vibration.

[0024] Please see the appendix Figure 1 Appendix Figure 4 and appendix Figure 5The bottom of the copper insert body 1 is provided with a reinforcing component 3, which includes a cross-shaped anti-torsion boss 301. There are four sets of cross-shaped anti-torsion bosses 301. The four sets of cross-shaped anti-torsion bosses 301 are circumferentially distributed and fixedly installed on the bottom surface of the copper insert body 1. Each of the four sets of cross-shaped anti-torsion bosses 301 has an exhaust hole 302 at the bottom. The exhaust hole 302 is located in the middle of the bottom of the cross-shaped anti-torsion boss 301. The bottom of the copper insert body 1 has four sets of radial guide grooves 303. The four sets of radial guide grooves 303 are respectively located between adjacent cross-shaped anti-torsion bosses 301.

[0025] The vent 302 is opened from the bottom of the cross-shaped anti-torsion boss 301, and the outlet is on the inner wall of the copper insert body 1. The vent 302 is directly connected to the internal space of the copper insert body 1. During assembly or operation, the residual air or process gas inside the copper insert body 1 can be discharged through the inner wall outlet to avoid internal cavities and bubbles caused by gas stagnation.

[0026] Specifically, through the reinforced component 3, four sets of cross-shaped anti-torsion bosses 301 are distributed around the bottom circumference of the copper insert body 1, which can improve the torsional strength and enhance the structural stability. The vent holes 302 opened at the bottom of the cross-shaped anti-torsion bosses 301 form a gas discharge channel during assembly and operation, avoiding pressure abnormalities and installation deviations caused by air resistance. The radial guide grooves 303 are located between adjacent bosses, which can quickly drain the liquid and impurities accumulated at the bottom and prevent them from affecting the sealing effect. The three work together to not only improve the mechanical strength of the copper insert body 1, but also optimize fluid management and pressure balance, ensuring that the copper insert body 1 can operate reliably under complex working conditions.

[0027] The working principle of this utility model is as follows: This utility model is a copper insert for preventing leakage. First, the main sealing ring 205 is embedded inside the main sealing groove 201, directly bearing the medium pressure. It fills the gap between the copper insert body 1 and the outer substrate through elastic deformation. The secondary sealing ring 206 is installed inside the secondary sealing groove 202. When the main sealing ring 205 leaks due to aging or pressure fluctuations, the secondary sealing ring 206 immediately provides redundant sealing to prevent further medium penetration. The spiral guide groove 204, with its spiral angle design, requires the medium to spiral upward along the groove to contact the next level of seal. The leakage rate is reduced through the labyrinth effect. The spiral structure induces medium turbulence, causing particulate impurities in the fluid to separate due to centrifugal force and remain at the bottom of the groove. At the same time, it buffers pressure fluctuations and prevents the sealing ring from being squeezed out due to sudden pressure changes. The dustproof ring 207 is installed in the uppermost dustproof groove 203 to intercept solid particles, moisture, and other impurities. Firstly, the material prevents the seal from intruding into the sealing area and wearing down the sealing ring, thus extending the life of the sealing assembly. Secondly, four sets of cross-shaped anti-torsion bosses 301 are evenly distributed around the circumference, and their cross-shaped cross-sections form an orthogonal mechanical interlock with the outer substrate. When the copper insert body 1 is subjected to torque, the boss arm and the substrate material interlock with each other, preventing sealing failure caused by rotation. The vent hole 302 extends from the bottom of the boss to the inner wall of the copper insert, quickly expelling the internal trapped air during injection molding or fluid filling, avoiding defects in the joint surface caused by cavitation. At the same time, it balances the air pressure difference between the inner wall and the outside during operation, preventing deformation of the body or displacement of the sealing ring caused by uneven pressure. The radial guide groove 303 is located between adjacent bosses. When liquid, condensate, or impurities accumulate at the bottom, they can be quickly discharged radially along the groove, preventing them from corroding the root of the boss or seeping into the sealing area. At the same time, it reduces local pressure concentration at the bottom and improves structural durability.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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.
