Description

Technical Field

[0001] This utility model relates to the field of valve bodies, and in particular to an impact-resistant valve body. Background Technology

[0002] A valve is a device used to control the flow of fluids (such as water, steam, gas, oil, etc.) in pipelines or equipment. It regulates the flow rate and pressure of fluids by opening, closing, or partially opening, and is widely used in many fields such as industrial production, building water supply and drainage systems, and domestic water use. The valve body is an important component of a valve, which usually refers to the outer shell of the valve that houses the closing element (such as the valve disc, gate, etc.) and guides the flow of fluid.

[0003] Existing gate valves lack protective structures for the valve body during use. The impact force of water or air flow usually acts directly on the valve body. Long-term exposure to direct impact can easily lead to fatigue damage of the valve body material, shortening its service life. Furthermore, the direct impact of water or air flow on the valve body may damage the seal between the valve body and the pipeline, resulting in media leakage and reducing the practicality of the valve body. Summary of the Invention

[0004] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides an impact-resistant valve body to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-impact valve body, comprising a valve body body, a flange at each of the left and right ends of the valve body body, a connecting ring at the water inlet end of the valve body body, the connecting ring fitting against the outer side of the flange near the water inlet end of the valve body body, and a concentric insert on one side of the connecting ring, the insert being movably inserted into the inner side of the water inlet end of the valve body body.

[0006] A sealing silicone sheet is attached to the side of the connecting ring near the insert and to the outer surface of the insert. The sealing silicone sheet on the insert is tightly attached to the inner ring of the valve body.

[0007] The first hole plate and the second hole plate are movably installed inside the insert, and a support ring is fixed inside the insert. The left and right opposite surfaces of the first hole plate and the second hole plate are connected by rubber pads, and the holes on the first hole plate and the second hole plate are misaligned.

[0008] The second orifice plate is located inside the first orifice plate;

[0009] Several spring rods are movably passed through the side surface of the support ring. After passing through the side surface of the support ring, the spring rods are connected to the second hole plate. Each spring rod is movably fitted with a spring, and the two ends of the spring are respectively connected to the side surface of the support ring and the side surface of the second hole plate.

[0010] Preferably, a silicone ring is attached to the end of the connecting ring away from the flange, and the connecting ring, the silicone ring, and the inner ring of the insert are flush.

[0011] Preferably, the flange has a plurality of connection holes, and the connecting ring, the sealing silicone sheet, and the silicone ring have through holes corresponding to the connection holes.

[0012] Preferably, a limiting block is fixedly installed on the inner side of the water inlet end of the valve body, and the limiting block is in contact with the side surface of the insert and the support ring.

[0013] Preferably, the side surfaces of the flange, connecting ring, and sealing silicone sheet are flush.

[0014] The beneficial effects of this utility model are:

[0015] This invention incorporates a first orifice plate and a second orifice plate. The dual-orifice plate design increases the complexity of the medium path, generating more turbulence and disturbance, further dispersing the impact force and enhancing the buffering effect. Furthermore, the staggered arrangement of the holes on the first and second orifice plates allows for a more uniform distribution of airflow, preventing excessive local pressure and reducing impact on the valve body. The spring provides an additional buffer layer, further improving the valve body's impact resistance, reducing fatigue damage caused by direct impact, and enhancing the seal between the valve body and the pipeline, reducing medium leakage and improving the valve body's practicality.

Detailed Implementation

[0020] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0021] like Figure 1 As shown, this utility model provides an impact-resistant valve body, including a valve body body 1, and a flange 2 is provided at each of the left and right ends of the valve body body 1.

[0022] like Figures 1 to 3 As shown, in this embodiment, a connecting ring 3 is provided on the left side of the valve body 1. The connecting ring 3 is in contact with the left end face of the flange 2 on the left end, and a concentric insert 6 is provided on the right end of the connecting ring 3. The insert 6 is movably inserted into the inner left end of the valve body 1.

[0023] A sealing silicone sheet 4 is attached to the right end face of the connecting ring 3 and the outer circumference of the insert 6. The sealing silicone sheet 4 on the connecting ring 3 and the insert 6 is an integrated structure. The sealing silicone sheet 4 on the insert 6 is tightly attached to the inner ring of the valve body 1 to improve the sealing performance of the connection between the insert 6 and the valve body 1.

[0024] The first hole plate 7 and the second hole plate 8 are movably installed inside the insert 6, and a support ring 10 is fixed inside the insert 6. The left and right opposite surfaces of the first hole plate 7 and the second hole plate 8 are connected by rubber pads 9, and the holes on the first hole plate 7 and the second hole plate 8 are misaligned.

[0025] The second orifice plate 8 is located to the right of the first orifice plate 7;

[0026] A number of spring rods 11 are horizontally movably passed through the side surface of the support ring 10. The spring rods 11 move through the left and right end faces of the support ring 10 and are connected to the right end face of the second hole plate 8. Each spring rod 11 is movably fitted with a spring 12. The two ends of the spring 12 are respectively connected to the side surface of the support ring 10 and the side surface of the second hole plate 8.

[0027] Among them, the side surfaces of flange 2, connecting ring 3 and sealing silicone sheet 4 are flush, which improves the overall aesthetics of the valve;

[0028] In this embodiment, a silicone ring 5 is attached to the end of the connecting ring 3 away from the flange 2, and the connecting ring 3, the silicone ring 5 and the inner ring of the insert 6 are flush, which improves the sealing performance of the connection between the connecting ring 3 and the flange on the external pipeline, thereby indirectly improving the sealing performance of the valve connection pipeline.

[0029] In this embodiment, the flange 2 is provided with a number of connection holes 14, and the connecting ring 3, the sealing silicone sheet 4 and the silicone ring 5 are provided with through holes corresponding to the connection holes 14, so as to facilitate the fixed connection between the flange 2 on the valve body 1 and the flange on the external pipeline through the connection holes 14 and the through holes.

[0030] In this embodiment, a limiting block 13 is fixedly installed on the inner side of the water inlet end of the valve body 1. The limiting block 13 is in contact with the side surface of the insert 6 and the support ring 10, which facilitates the use of the limiting block 13 to provide auxiliary support for the insert 6 and the support ring 10, thereby improving the stability of the insert 6 and the support ring 10.

[0031] Specifically, when using a valve assembled from this valve body, the valve body is connected to an external pipeline via flange 2, connecting ring 3, sealing silicone sheet 4, and connecting holes on silicone ring 5, thereby connecting the valve body to an external pipeline.

[0032] When the medium flows into the valve body 1 through the external pipe, it passes through the holes on the first orifice plate 7 and the second orifice plate 8 in sequence. The design of the first orifice plate 7 and the second orifice plate 8 increases the complexity of the path of the flowing medium, generating more turbulence and disturbance, further dispersing the impact force and enhancing the buffering effect. In addition, the staggered design of the holes on the first orifice plate 7 and the second orifice plate 8 can distribute the airflow more evenly, avoid excessive local pressure, and reduce the impact on the valve body 1. The rubber pad 9 connecting the first orifice plate 7 and the second orifice plate 8 can ensure that the relative position between the two first orifice plates 7 and the second orifice plate 8 is fixed, enhancing the overall structural stability. The second orifice plate 8 is connected to the support ring 10 through the spring 12, which can provide an additional buffer layer to reduce the impact of the flowing medium on the valve body 1, reduce the damage to the valve body 1 caused by the impact, and provide more effective protection for the valve body.
