Abstract
Description
Technical Field
[0001] The present application belongs to the field of valve technology, and more specifically, relates to a suspension bridge reinforced butterfly valve plate. Background Art
[0002] The valve plate is one of the core components of the butterfly valve. By rotating the valve plate, the fluid flow through the butterfly valve can be adjusted, thereby accurately controlling the medium flow in the pipeline.
[0003] In the related art, the edge areas of the valve plate on both sides of the center axis of the valve plate belong to the edge of the valve plate, and the structure of this edge is usually relatively weak. When water flows through the butterfly valve, the pressure exerted by the water flow on the valve plate tends to be concentrated on the edge, resulting in a greater water pressure impact on this part. When the water pressure impact is large, the deformation of the edge is usually large, which affects the working performance and service life of the butterfly valve, and it is urgently needed to be improved. Utility Model Content

The edge of the valve plate can better resist deformation when it is locally pulled, so that the edge of the valve plate is strengthened and the strength of the edge of the valve plate is improved.
[0008] As a further preference, the length direction of the main reinforcing ribs is parallel to the central axis of the plate body, and the length direction of the supporting reinforcing ribs is perpendicular to the central axis of the plate body.

[0013] As a further preferred embodiment, the inner side of the annular reinforcement block is protruded along the thickness direction of the plate body to form an annular limiting protrusion

[0025] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0026] The following is combined with Figure 1-4 This application is described in further detail.
[0027] The embodiment of the present application discloses a suspension bridge reinforced butterfly valve plate. Figure 1 and Figure 2 The suspension bridge reinforced butterfly valve plate includes a plate body 1, and the edge of the plate body 1 is connected with a main reinforcement rib 2 and a plurality of branch reinforcement ribs 3, wherein both ends of the main reinforcement rib 2 extend toward the edge of the plate body 1, and the plurality of branch reinforcement ribs 3 are connected to the main reinforcement rib 2, and the plurality of branch reinforcement ribs 3 extend from the main reinforcement rib 2 to the edge of the plate body 1, and the plurality of branch reinforcement ribs 3 and the main reinforcement rib 2 together form a suspension bridge reinforcement structure at the edge of the plate body 1.
[0028] Under this design, after the plate body 1 is added with a suspension bridge reinforcement structure composed of a main reinforcement rib 2 and a plurality of support reinforcement ribs 3, the force direction of the suspension bridge reinforcement structure is exactly opposite to that of an actual suspension bridge; at this time, the main reinforcement rib 2 acts as a "main cable" and the support reinforcement rib 3 acts as a "sling", and the "main cable" that should have been curved is now a straight line and is partially tensile, and then the soft "slings" are replaced with support reinforcement ribs 3, which greatly improves the structural stiffness, so that the edge of the valve plate can better resist deformation when it is locally tensile, and the edge of the valve plate is strengthened, thereby improving the structural strength of the valve plate.
[0029] Furthermore, the plate body 1 is preferably an arc-shaped plate, and the suspension bridge reinforcement structure is located on the concave surface of the arc-shaped plate; the main reinforcement ribs 2 and the support reinforcement ribs 3 in the suspension bridge reinforcement structure are integrally connected to the plate body 1, so that the overall structural stability of the valve plate is greatly improved. Preferably, the plate body 1, the main reinforcement ribs 2 and the support reinforcement ribs 3 in the valve plate are made by an integrated casting process.
[0030] Furthermore, the length direction of the main reinforcing rib 2 is preferably parallel to the central axis of the plate body 1, and the length direction of the supporting reinforcing rib 3 is preferably perpendicular to the central axis of the plate body 1. The spacing between the main reinforcing rib 2 and the supporting reinforcing rib 3, as well as the number of the supporting reinforcing ribs 3 can be designed and adjusted according to the size of the plate body 1.
[0031] For example, when the valve plate is applied to a DN600-PN16 butterfly valve, the number of the branch reinforcement ribs 3 at the same edge is preferably set to 9, and the spacing between two adjacent branch reinforcement ribs 3 is preferably 20 mm; and between the two edge portions of the plate body 1, the spacing between the two main reinforcement ribs 2 is preferably 300 mm.
[0032] Furthermore, an annular reinforcement block 4 is fixed to the plate body 1, and both ends of the main reinforcement rib 2 and one end of the supporting reinforcement rib 3 extending to the edge of the plate body 1 are connected to the inner side of the annular reinforcement block 4. A gap is left between the outer circular surface of the annular reinforcement block 4 and the circumferential surface of the plate body 1 for the subsequent installation of a sealing ring; an annular limiting protrusion 6 is formed on the inner side of the annular reinforcement block 4 along the thickness direction of the plate body 1 for positioning the pressure plate to be installed later; the end face of the annular reinforcement block 4 has a plurality of threaded holes 5 for locking the pressure plate with bolts later.
[0033] In this design, the annular reinforcement block 4 can not only strengthen the structural strength of the valve plate, but also serve as an installation base for the pressure plate, so that the pressure plate can clamp the sealing ring in the above-mentioned gap to achieve the installation of the sealing ring.
[0034] Furthermore, an annular anti-slip groove 7 is provided on the surface of the plate body 1, and the annular anti-slip groove 7 is cocentric with the annular reinforcement block 4, and the annular anti-slip groove 7 is located outside the annular reinforcement block 4. When installing the sealing ring, if the inner side of the sealing ring has a flange, the flange can be pressed into the annular anti-slip groove 7, the sealing ring is buckled on the surface of the plate body 1 through the pressure plate, and then the bolts are installed at the threaded holes 5, and the pressure plate is locked by the bolts to achieve stable installation of the sealing ring.
[0035] Further, see Figure 1 , Figure 3 and Figure 4 The plate body 1 is also provided with a mounting structure 8 for mounting the shaft rod, and the mounting structure 8 is located at the central axis of the plate body 1. Preferably, the mounting structure 8 is mounted on the convex surface of the plate body 1 and includes two seats.
[0036] Specifically, the two seats are mirror-imaged at the edge of the plate body 1, and a through hole 9 for installing the shaft rod is provided through the seat body, and the through hole 9 is coaxial with the central axis of the plate body 1. To ensure the stable installation of the shaft rod, a positioning hole 10 connected to the through hole 9 is provided on the outer surface of the seat body for installing fasteners such as positioning pins and bolts. Of course, in other embodiments, the mounting structure 8 can also adopt other tubular structures such as an integrated or segmented one.
