Description

Technical Field

[0001] This application relates to the technical field of valves, and in particular to an anti-impact butterfly valve. Background Technology

[0002] A butterfly valve is a type of valve whose closing element (valve disc or butterfly plate) is a disc that rotates around the valve shaft to achieve opening and closing. The valve can be used to control the flow of various types of fluids, such as air, water, steam, various corrosive media, mud, oil, liquid metals and radioactive media.

[0003] Regarding the aforementioned technologies, the applicant believes that existing butterfly valves, due to long-term fluid transport and the long-term impact of large fluid flow rates, are prone to butterfly plate deformation, which affects the sealing performance of the butterfly valve and needs improvement. Utility Model Content

[0004] In order to improve the impact resistance of the butterfly plate and reduce its deformation to maintain the sealing performance of the butterfly valve, this application provides an impact-resistant butterfly valve.

[0005] The anti-impact butterfly valve provided in this application adopts the following technical solution:

[0006] An anti-impact butterfly valve includes a valve body, a valve stem, and a butterfly plate. The butterfly plate is provided with a reinforcing structure, which includes a main reinforcing rib and side reinforcing parts. The main reinforcing rib is fixed to the middle of the butterfly plate, and the side reinforcing parts are disposed on both sides of the main reinforcing rib. The side reinforcing parts include intersecting diagonal reinforcing ribs, which are longitudinally spaced on both sides of the main reinforcing rib.

[0007] By adopting the above technical solution, the main reinforcing ribs and side reinforcing parts are used to improve the impact resistance of the butterfly plate. The intersecting diagonal reinforcing ribs increase the reinforcing points, resulting in a better reinforcement effect on the structure and reducing the deformation of the butterfly plate to maintain the sealing performance of the butterfly valve.

[0008] Preferably, the side reinforcement further includes a support protrusion fixed to the middle of the intersecting diagonal reinforcing ribs.

[0009] By adopting the above technical solution, the supporting protrusions further strengthen the middle part of the intersecting diagonal reinforcing ribs, thereby increasing the structural strength of the central part of the butterfly plate.

[0010] Preferably, the cross-section of the inclined reinforcing rib is a triangle with a high center and low sides.

[0011] By adopting the above technical solution, the diagonal reinforcing ribs, which are higher in the middle and lower on both sides, provide better support for the central support protrusion and achieve higher stability.

[0012] Preferably, an impact-resistant panel parallel to the butterfly plate is fixed on the main reinforcing rib, and the supporting protrusions located on both sides of the main reinforcing rib are fixed to the circumferential edge of the impact-resistant panel.

[0013] By adopting the above technical solution, an impact-resistant panel is set up, and a second impact-resistant plane is added to the butterfly plate to improve the impact resistance of the butterfly plate; the main reinforcing ribs and supporting protrusions are used to support the impact-resistant panel.

[0014] Preferably, a deformable connecting column is fixed on the side wall of the impact-resistant panel, and a connecting groove for positioning the connecting column is provided on the side wall of the main reinforcing rib.

[0015] By adopting the above technical solution, the cooperation between the connecting column and the connecting groove facilitates the disassembly of the impact-resistant panel, making the cleaning operation of the butterfly plate easier.

[0016] Preferably, the diagonal reinforcing ribs are fixed on opposite side walls with downwardly inclined and backward-extending reinforcing ribs.

[0017] By adopting the above technical solution, reinforcing ribs are used to improve the structural strength of diagonal reinforcing bars.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] The main reinforcing ribs and side reinforcements are designed to improve the impact resistance of the butterfly plate. The intersecting diagonal reinforcing ribs increase the number of reinforcement points, resulting in better structural reinforcement and reducing the deformation of the butterfly plate to maintain the sealing performance of the butterfly valve.

[0020] The support protrusions further strengthen the middle of the intersecting diagonal reinforcing ribs, increasing the structural strength of the center of the butterfly plate. The diagonal reinforcing ribs, which are high in the middle and low on both sides, provide better support for the support protrusions in the middle. The reinforcing ribs are used to improve the structural strength of the diagonal reinforcing ribs, resulting in higher stability.

[0021] An impact-resistant panel is installed, adding a second impact-resistant plane to the butterfly plate to improve its impact resistance; the main reinforcing ribs and supporting protrusions support the impact-resistant panel; and the impact-resistant panel is removable, making the butterfly plate easier to clean.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] This application discloses an anti-impact butterfly valve, referring to... Figure 1 The valve includes a valve body 1, a valve stem 2, and a butterfly plate 3. The butterfly plate 3 is provided with a reinforcing structure 4, which includes a main reinforcing rib 5 and a side reinforcing part 6. The main reinforcing rib 5 is fixed to the middle of the butterfly plate 3, and the side reinforcing part 6 is provided on both sides of the main reinforcing rib 5. The side reinforcing part 6 includes intersecting diagonal reinforcing ribs 61, which are longitudinally spaced on both sides of the main reinforcing rib 5.

[0028] Reference Figure 1 The side reinforcement 6 also includes a support protrusion 62 fixed to the middle of the intersecting diagonal reinforcement ribs 61; the support protrusion 62 further reinforces the middle of the intersecting diagonal reinforcement ribs 61, increasing the structural strength of the center of the butterfly plate 3; the cross section of the diagonal reinforcement ribs 61 is a triangle with a high middle and low sides, and the middle of the diagonal reinforcement ribs 61 is at the same height as the support protrusion 62, thereby making the support effect of the diagonal reinforcement ribs 61 with a high middle and low sides on the support protrusion 62 in the middle better and more stable.

[0029] Reference Figure 1 The diagonal reinforcing rib 61 has downwardly inclined and backward-extending reinforcing ribs 611 fixed on the opposite side walls. The reinforcing ribs 611 are used to improve the structural strength of the diagonal reinforcing rib 61.

[0030] Reference Figure 1 An impact-resistant panel 7 parallel to the butterfly plate 3 is fixed on the main reinforcing rib 5. The support protrusions 62 on both sides of the main reinforcing rib 5 abut against the circumferential edge below the impact-resistant panel 7. The impact-resistant panel 7 is set to add a second impact-resistant plane on the butterfly plate 3 to improve the impact resistance of the butterfly plate 3. The main reinforcing rib 5 and the support protrusions 62 provide support for the impact-resistant panel 7.

[0031] Reference Figure 1 A deformable connecting post 71 with an enlarged diameter at its end is fixed to the side wall of the impact-resistant panel 7. The connecting post 71 is made of rubber. A connecting groove 51 is provided on the side wall of the main reinforcing rib 5 for the enlarged diameter end of the connecting post 71 to deform and engage. The connecting post 71 can be disengaged from the connecting groove 51 by deformation, which facilitates the disassembly of the impact-resistant panel 7 and makes the cleaning operation of the butterfly plate 3 easier. At the same time, the rubber material has a certain degree of sealing, which can prevent water from entering the connecting groove 51.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
