[0002] The pipe stripping machine of the continuous rolling mill is an important device used in the continuous rolling production line. Its main function is to remove the scale, rust and other bad surface impurities on the strip surface before the hot continuous rolling of the metal strip, so as to ensure the product quality after rolling. The pipe stripping machine usually uses high-pressure water jets or chemical solutions to clean the surface of the metal strip to remove scale and other impurities. In order to ensure the sealing performance after the connection of the device pipelines, a water sealing ring is required.

[0003] In the prior art, there are the following defects: the connection between the water nozzle of the cooling water of the pipe stripping machine frame and the pipe stripping machine frame is sealed by a metal seal. However, the functionality of the metal seal will decline after long-term use, which may cause water leakage, small water inflow to the frame and damage to the frame. Therefore, it is necessary to improve its sealing form to seal the incoming water, extend the service life of the frame and ensure the product quality.

[0024] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0025] Refer to Figure 1 - Figure 2, an embodiment provided by the present utility model: a water seal ring with good sealing effect, including a sleeve 1. The sleeve 1 is made of polyurethane material as a whole and has certain softness. A connecting groove 2 is provided on the inner wall of the sleeve 1. The connecting groove 2 is mainly communicated with one end of the pipeline. A conical groove 4 is provided on the inner wall of the sleeve 1. The conical groove 4 can be connected to the other end of the pipeline. The inner wall of the conical groove 4 is closely attached to the pipeline to achieve the sealing effect. A through hole 3 is provided between the connecting groove 2 and the conical groove 4. Through the through hole 3, cooling water can be transferred from one end of the pipeline to the other end of the pipeline. Two groups of mounting rings 5 are respectively fixedly connected to both sides of the sleeve 1. The mounting rings 5 are made of metal materials and can be connected to the sleeve 1 by welding. A sealing component is provided on the inner wall of the mounting ring 5.

[0026] Refer to Figure 3 , an anti-wear layer 8 is fixedly connected to the inner wall of the sleeve 1. A fireproof layer 9 is fixedly connected to the inner wall of the anti-wear layer 8. The fireproof layer 9 is a water-based flame retardant coating. The water-based flame retardant coating can release flame retardant gas or form a carbonized layer when heated, thereby slowing down the spread of fire. An acoustic isolation layer 10 is fixedly connected to the inner wall of the fireproof layer 9. The acoustic isolation layer 10 is a barrier film made of polyethylene film, polyvinyl chloride film, etc., which can reduce the noise generated during the transmission of cooling water. An anti-corrosion layer 11 is fixedly connected to the inner wall of the acoustic isolation layer 10. The anti-corrosion layer 11 is a composite material coating, usually composed of polyester resin and fiberglass reinforced material, which can effectively protect the polyurethane pipeline from corrosion and damage.

[0027] Refer to Figure 1 - Figure 2 , the sealing component includes an airbag 6. The airbag 6 is fixedly connected to the inner wall of the mounting ring 5. The airbag 6 is made of rubber material, which can improve the sealing performance by making the surface of the pipeline in contact. An air injection hole 7 is provided at the top of the airbag 6. The air injection hole 7 is communicated with the airbag 6, and air can be input into the airbag 6 through the air injection hole 7. The air injection hole 7 penetrates and is fixedly connected to the inner wall of the mounting ring 5.

[0028] Working principle: First, when the sleeve 1 is in use, the pipeline can be connected to both ends of the sleeve 1. By using the conical shape of the conical groove 4, the inner wall of the conical groove 4 is closely attached to the outer wall of the pipeline to increase the sealing performance. At the same time, air is conveyed to the air injection hole 7 through an air gun, so that the airbag 6 expands and contacts the outer wall of the pipeline, further improving the sealing performance of the sleeve 1, the connecting pipe and the conical pipe. When the sleeve 1 is in use, if the ground or an object rubs against the surface of the sleeve 1, the anti-wear layer 8 reduces the degree of wear. In case of a fire, the fireproof layer 9 reduces the spread of fire to the sleeve 1 and the connection part. When the sleeve 1 conveys liquid, the acoustic isolation layer 10 reduces the noise generated by the water flow impact, improving the quality of the working environment, and the anti-corrosion layer 11 is used to prevent the liquid from containing corrosiveness from reducing the service life of the sleeve 1.

[0029] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
