Description

Technical Field

[0001] This utility model relates to the field of valve protection technology, specifically to a split-type valve protection structure. Background Technology

[0002] Currently, gate valves in underground pipe networks are usually installed in valve wells. In order to reduce costs and extend the service life of gate valves, plastic gate valves are usually used. To protect the plastic gate valves and prevent soil from falling from the inner wall of the valve well and damaging them, the valve well is usually reinforced by building a brickwork structure inside the valve well.

[0003] However, constructing brick-lined valve wells typically requires a long construction period. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model proposes a split-type valve protection structure.

[0005] To achieve the above-mentioned technical effects, the present invention adopts the following solution:

[0006] A split-type valve protection structure includes a support plate, a cylinder, a protective cover seat, and a flip cover. The support plate is fixedly mounted on the valve's pipe body. The cylinder is fixedly mounted on the upper end of the support plate, and the valve is located inside the cylinder. The protective cover seat is fixedly mounted on the upper end of the cylinder. The protective cover seat has an opening that matches the flip cover, and the flip cover is hinged inside the opening.

[0007] In a preferred embodiment, the support plate includes a coupling plate, a pressure plate, and an anti-sinking plate. The coupling plate has a first central hole at its center, and the pressure plate has a second central hole at its center. The tube passes through the first and second central holes. The pressure plate is located at the upper end of the coupling plate. A rubber ring is clamped between the pressure plate and the coupling plate, and the inner side of the rubber ring is pressed against the outer wall of the tube. The anti-sinking plate has a third central hole at its center. The anti-sinking plate is fixedly located at the upper end of the coupling plate and surrounds the pressure plate. The lower end of the tube is fixedly connected to the anti-sinking plate.

[0008] In a preferred embodiment, a first clamping ring is fixedly provided on the inner side of the coupling plate, the upper end of the first clamping ring being lower than the upper end of the coupling plate; a second clamping ring is fixedly provided on the inner side of the pressure plate, the lower end of the second clamping ring extending downward to the inner side of the coupling plate; and a rubber ring is clamped between the first clamping ring and the second clamping ring.

[0009] In a preferred embodiment, the coupling plate and the pressure plate are fixed together by bolts, and the anti-sinking plate and the coupling plate are fixed together by bolts.

[0010] In a preferred embodiment, the flip cover is fan-shaped, and a connecting block extends outward from the center of the flip cover. The edge of the opening has a notch that matches the connecting block. The lower end of the protective cover base is fixedly provided with a rotating shaft located below the notch, and the connecting block is rotatably mounted on the rotating shaft.

[0011] In a preferred embodiment, the inner side of the opening is provided with a support edge for supporting the flip cover.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] A split-type valve protection structure includes a support plate, a cylinder 1, a protective cover 3, and a flip cover 4. The support plate is fixedly mounted on the valve tube 16. The cylinder 1 is fixedly mounted on the upper end of the support plate, and the valve is located inside the cylinder 1. The protective cover 3 is fixedly mounted on the upper end of the cylinder 1. The protective cover 3 has an opening 5 that matches the flip cover 4. The flip cover 4 is hinged in the opening 5.

[0021] The valve is protected by the combined action of the support plate, cylinder 1, protective seat, and flip cover 4, preventing water corrosion and damage from falling soil. The flip cover 4 is easy to open for inspection and maintenance. In addition, the flip cover 4 and the protective seat can be connected by an anti-theft lock for theft prevention.

[0022] Furthermore, the structure is easy to install, which greatly improves the construction speed compared to the construction of valve wells.

[0023] In a preferred embodiment, the support plate includes a coupling plate 10, a pressure plate 11, and an anti-sinking plate 2. The coupling plate 10 has a first central hole, and the pressure plate 11 has a second central hole. The coupling plate 10 and pressure plate 11 are fitted onto the valve body 16 through the first and second central holes. Typically, the valve is vertically installed at the upper end of the underground pipe network 15. The valve includes a valve body 17, the lower end of which is connected to the upper end of the underground pipe network 15 through the pipe body 16. The pressure plate 11 is located at the upper end of the coupling plate 10. A rubber ring 14 is clamped between the pressure plate 11 and the coupling plate 10. The inner side of the rubber ring 14 is attached to the outer wall of the tube body 16, so that the pressure plate 11 and the coupling plate 10 are installed on the tube body 16 by the friction between the rubber ring 14 and the tube body 16 and will not fall off. In addition, the rubber ring 14 can provide a seal. The anti-sinking plate 2 has a third center hole in its center. The anti-sinking plate 2 is fixedly set on the upper end of the coupling plate 10 and surrounds the pressure plate 11. The pressure plate 11 is located in the third center hole. The lower end of the cylinder 1 is fixedly connected to the anti-sinking plate 2.

[0024] After installation, there is a certain distance between the protective cover at the top of the cylinder and the top of the valve inside, and it is fixed by the friction between the rubber ring and the pipe body. Therefore, after the ground settles, it will first press on the protective cover and not directly on the valve.

[0025] In a preferred embodiment, a first clamping ring 12 is fixedly provided on the inner side of the coupling plate 10, the upper end of the first clamping ring 12 being lower than the upper end of the coupling plate 10. A second clamping ring 13 is fixedly provided on the inner side of the pressure plate, the lower end of the second clamping ring 13 extending downward to the inner side of the coupling plate 10. The rubber ring 14 is clamped between the first clamping ring 12 and the second clamping ring 13. Furthermore, the lower end of the second clamping ring 13 on the inner side of the pressure plate is lower than the upper end of the coupling plate 10, thereby serving a limiting function.

[0026] In a preferred embodiment, the coupling plate 10 is fixed to the pressure plate by bolts, and the anti-sinking plate 2 is fixed to the coupling plate 10 by bolts. This facilitates installation and disassembly.

[0027] In a preferred embodiment, the flip cover 4 is fan-shaped, and a connecting block 7 extends outward from the rear end of the center of the flip cover 4. The edge of the opening 5 is provided with a notch 6 that matches the connecting block 7. The lower end of the protective cover base 3 is fixedly provided with a rotating shaft 9 located below the notch 6, and the connecting block 7 is rotatably mounted on the rotating shaft 9.

[0028] In a preferred embodiment, the inner side of the opening 5 is provided with a support edge 8 for supporting the flip cover 4.
