Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of check valves, in particular to a valve disc structure for a check valve. Background Technique
[0002] A check valve is a kind of valve, also known as a non-return valve or a reverse valve. Its main function is to prevent the flowing medium from flowing back in the pipeline. When the flow direction of the medium in the pipeline changes, the check valve will automatically close to prevent the medium from flowing back and protect the safety of the pipeline and equipment. Check valves are widely used in chemical industry, petroleum, natural gas, water treatment, food processing, etc. Currently, the common check valve performs the check process through the valve disc inside it. When the medium passes forward, the valve disc is opened by the impact of the medium. When the medium passes backward through the inside of the check valve, the medium acts on the surface of the valve disc, causing the valve disc to fit against the through hole inside the check valve, making it difficult for the medium to pass through. However, the valve disc structure inside the existing check valve is simple. When performing check, it can only cover the through hole inside the check valve through the valve disc. But when the valve disc is deformed, a large gap will be generated between the valve and the through hole, easily causing the medium to flow back. Therefore, the technical personnel in this field provide a valve disc structure for a check valve to solve the problems raised in the above background technique. Content of the Utility Model
[0003] The purpose of the utility model is to provide a valve disc structure for a check valve to solve the problems raised in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:
[0005] A valve disc structure for a check valve includes a valve disc body. A connecting piece is fixedly connected to the top of the valve disc body. A rotating shaft is fixedly connected to the top of the connecting piece. An enhancing member is fixedly connected to the check side of the valve disc body, and the outer diameter of the enhancing member is smaller than the diameter of the valve disc body.
[0006] As a further scheme of the utility model: The enhancing member is arranged in a ring shape. A reinforcing rib is fixedly connected to the inner side of the enhancing member, and the reinforcing rib is fixedly connected to the check side of the valve disc body.
[0007] As a further scheme of the utility model: The reinforcing rib is arranged in a radial shape.
[0008] As a further scheme of the utility model: An inner groove is formed on the other surface of the valve disc body, and a sealing strip is clamped inside the inner groove.
[0009] As a further scheme of the utility model: The sealing strip is a component made of rubber material.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] By arranging a reinforcing member on the check side of the valve disc body and fixedly connecting a reinforcing rib inside the reinforcing member, the thickness of the valve disc can be increased, thereby enhancing the anti-deformation ability of the valve disc. Moreover, since the reinforcing rib is arranged in a radial pattern, a part of the weight can be reduced, facilitating the forward passage of the medium. A slope surface will be formed between the valve disc body and the reinforcing member, and the medium will exert a certain pressure on the surface of the valve disc body, that is, the outer side of the reinforcing member, thereby prompting the valve disc body to adhere to the check valve through-hole, blocking the check valve through-hole. Additionally, a sealing strip is arranged on the other side of the valve disc body. By using the sealing strip to abut against the edge of the check valve through-hole, the sealing effect can be further enhanced, preventing the reverse passage of the medium.

[0016] Please refer to Figures 1 to 3 , in an embodiment of the present utility model, a valve disc structure for a check valve includes a valve disc body 1. A connecting piece 2 is fixedly connected to the top of the valve disc body 1, and a rotating shaft 3 is fixedly connected to the top of the connecting piece 2. A reinforcing member 4 is fixedly connected to the check side of the valve disc body 1, and the outer diameter of the reinforcing member 4 is smaller than the diameter of the valve disc body 1. By arranging the reinforcing member 4, when the medium acts on the check side of the valve disc body 1, the medium will also act on the reinforcing member 4. Since the outer diameter of the reinforcing member 4 is smaller than the diameter of the valve disc body 1, a slope surface will be formed between the valve disc body 1 and the reinforcing member 4, and the medium will exert a certain pressure on the surface of the valve disc body 1, that is, the outer side of the reinforcing member 4, thereby prompting the valve disc body 1 to adhere to the check valve through-hole 9, blocking the check valve through-hole 9. Moreover, due to the arrangement of the reinforcing member 4, the overall thickness of the valve disc can be enhanced, and the strength against deformation can be increased.
[0017] Preferably, the reinforcing member 4 is arranged in a ring shape, and a reinforcing rib 5 is fixedly connected inside the reinforcing member 4. The reinforcing rib 5 is fixedly connected to the check side of the valve disc body 1.
[0018] Preferably, the reinforcing rib 5 is arranged in a radial pattern, which can reduce the overall weight of the valve disc.
[0019] Preferably, an inner groove 6 is formed on the other surface of the valve disc body 1, and a sealing strip 7 is clamped inside the inner groove 6.
[0020] Preferably, the sealing strip 7 is a component made of rubber.
[0021] The working principle of the present utility model is as follows: when using this valve disc, when the medium passes through in the forward direction, the lower end of the valve disc can be lifted, so that the edge of the valve disc body 1 and the check valve through-hole 9 are separated from each other, facilitating the passage of the medium. When the medium passes through the check valve equipped with this valve disc in the reverse direction, the medium will act on the check side surface of the valve disc body 1. And by providing the reinforcing member 4, a slope surface will be formed between the valve disc body 1 and the reinforcing member 4. The medium will form a certain pressure on the surface of the valve disc body 1, that is, the outer side of the reinforcing member 4, so as to prompt the valve disc body 1 to adhere to the check valve through-hole 9 and block the check valve through-hole 9. And due to the provision of the reinforcing member 4, the overall thickness of the valve disc can be enhanced, and the strength of the valve disc against deformation can be enhanced. When the valve disc body 1 blocks the check valve through-hole 9, the sealing strip 7 will be abutted against the edge of the check valve through-hole 9, which can further enhance the sealing effect and prevent the medium from passing through in the reverse direction.
[0022] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and should be covered within the protection scope of the present utility model.
