[0004] Most of the existing rubber seals inside the valve core do not have a reinforced structure. After the valve core is opened and closed for a long time, the rubber seals are easily deformed and lose the sealing effect. In addition, they do not have an anti-wear structure, which makes the rubber seals susceptible to rotational wear and causes valve core leakage. Utility Model Content

[0026] The utility model provides a valve core rubber seal with good sealing effect, which aims to solve the problem that most of the existing rubber seals inside the valve core do not have a reinforcement structure, the rubber seals are easily deformed after the valve core is opened and closed for a long time, resulting in a loss of sealing effect, and the rubber seals do not have an anti-wear structure, resulting in the rubber seals being easily subject to rotational wear and causing valve core leakage.

[0027] like Figure 1-5 As shown, an embodiment of the utility model provides a valve core rubber seal with good sealing effect, including a rubber seal body 1, a protective ring 2 is sleeved on the surface of the rubber seal body 1, a reinforcing ring 4 is provided on the inner wall of the rubber seal body 1, a limiting groove 9 is opened on the top of the rubber seal body 1, a limiting block 3 is fixedly connected to the inner wall of the protective ring 2, the surface of the limiting block 3 is in close contact with the inner wall of the limiting groove 9, and the number of the limiting grooves 9 and the limiting blocks 3 are both several and are evenly distributed on the top of the rubber seal body 1 and the inner wall of the protective ring 2.

[0028] In the technical solution of the utility model, by moving the reinforcement ring 4 to the inside of the rubber seal body 1, the plug block 5 is tightly inserted into the inside of the limit groove 9, and then the protective ring 2 is sleeved on the surface of the rubber seal body 1, so that the limit block 3 is tightly inserted. At this time, the reinforcement ring 4 will reinforce the rubber seal body 1 to avoid the problem that the rubber seal body 1 is easily deformed and loses the sealing effect after the valve core is opened and closed for a long time, and the protection of the rubber seal body 1 by the protective ring 2 can avoid the problem that the rubber seal body 1 is easily subject to rotational wear and causes the valve core to leak. It avoids the problem that the rubber seal inside most of the existing valve cores does not have a reinforcement structure, and the rubber seal is easily deformed and loses the sealing effect after the valve core is opened and closed for a long time, and does not have an anti-wear structure, which causes the rubber seal to be easily subject to rotational wear and causes the valve core to leak.

[0029] Please refer to Figure 1 and Figure 3 The surface of the reinforcing ring 4 is fixedly connected with an insert block 5, and the number of the insert blocks 5 is several and evenly distributed on the surface of the reinforcing ring 4, and the surface of the insert block 5 is in close contact with the inner wall of the limiting groove 9. In this embodiment, by closely inserting the insert block 5 into the limiting groove 9, the reinforcing ring 4 can be connected to the rubber seal body 1 at this time, achieving the effect of conveniently connecting the reinforcing ring 4 to the rubber seal body 1.

[0030] For further information, please refer to Figure 3 The reinforcing ring 4 and the insert block 5 are made of polycarbonate thermoplastic plastic, and the bottom of the insert block 5 is in close contact with the top of the limit block 3. In this embodiment, since the reinforcing ring 4 and the insert block 5 are made of polycarbonate thermoplastic plastic, the reinforcing ring 4 and the insert block 5 have good toughness and weather resistance, and can effectively support the rubber seal body 1, thereby achieving the effect of preventing the rubber seal body 1 from deformation.

[0031] Please continue to refer to Figure 4 The surfaces of the protective ring 2 and the limit block 3 are both roughened and evenly sprayed with a primer layer 6, and the material of the primer layer 6 is epoxy resin paint. In this embodiment, by roughening the surface of the protective ring 2, the epoxy resin primer can be firmly sprayed on the surface of the protective ring 2, and the primer layer 6 can increase the adhesion of the weather-resistant layer 7, thereby achieving the effect of conveniently increasing the adhesion of the weather-resistant layer 7.

[0032] Please refer to Figure 4 The surface of the primer layer 6 is evenly sprayed with a weather-resistant layer 7, and the material of the weather-resistant layer 7 is acrylic resin paint. In this embodiment, by evenly spraying the weather-resistant layer 7 made of acrylic resin paint on the surface of the primer layer 6, the reinforcing ring 4 and the limit block 3 can be made corrosion-resistant, thereby achieving the effect of extending the service life of the reinforcing ring 4 and the limit block 3.

[0033] Also, please refer to Figure 4 The surface of the weather-resistant layer 7 is evenly sprayed with a wear-resistant layer 8, and the material of the wear-resistant layer 8 is polyurethane paint. In this embodiment, by evenly spraying the wear-resistant layer 8 of polyurethane paint on the surface of the weather-resistant layer 7, the weather-resistant layer 7 can be protected, and the protection time of the weather-resistant layer 7 on the reinforcing ring 4 and the limit block 3 is improved, thereby achieving the effect of protecting the weather-resistant layer 7.

[0034] Please refer to Figure 1 The rubber seal body 1, the protective ring 2 and the stopper 3 are all made of fluororubber. In this embodiment, since the rubber seal body 1, the protective ring 2 and the stopper 3 are all made of fluororubber, the fluororubber has good elasticity and weather resistance, and can further strengthen the sealing of the valve core, thereby achieving the effect of strengthening the sealing of the valve core.

[0035] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model.
