TECHNICAL FIELD
[0001] The utility model relates to the technical field of protective equipment, and specifically relates to a water release valve for a flood gate. BACKGROUND
[0002] A flood gate is a protective device used to prevent floodwater or accumulated water from entering the interior of a building. Its main function is to quickly close and seal the entrance when flood or heavy rain arrives, preventing water from entering the interior of the building, thereby protecting property and personnel safety. The water release valve of the flood gate is an important component of the flood gate system. Its role is to help drain the water that may accumulate behind the flood gate after it is closed, thereby reducing the water pressure behind the flood gate and ensuring that the flood gate can work effectively and protect the building.
[0003] Patent No. CN201120068286.9 discloses a flood gate water release valve. By staggering the positions of the valve holes on the valve cover and the through holes on the cover plate, the flood gate is released. The number of through holes is set to multiple. Compared to a single large opening, multiple small through holes can help reduce the impact of accumulated water on the flood gate. However, during floods or heavy rains, water flow may carry a large amount of debris, such as leaves, garbage, and silt. These debris can easily block these small-sized through holes, preventing normal drainage. SUMMARY
[0004] In view of the above, the purpose of the utility model is to provide a water release valve for a flood gate to solve the problem of easy blockage.
[0005] To achieve the above purpose, the utility model provides the following technical scheme:
[0006] A water release valve for a flood gate, comprising a valve body, a mesh cover, and a valve cover. The valve body has multiple water release holes at one end. The mesh cover covers all the water release holes and is connected to the valve body. The valve cover covers the other end of the valve body, and the valve cover has a plug body with multiple inserts corresponding to the water release holes. When the valve cover closes the valve body, the plug body is inserted into the valve body and seals all the water release holes, and the inserts are inserted into the corresponding water release holes.
[0007] As a further scheme of the utility model: wherein the multiple water release holes are the same size and are evenly distributed on the end face of the valve body.
[0008] As a further scheme of the utility model: wherein one end of the valve cover is rotatably connected to the valve body through a hinge, and the other end of the valve cover is detachably connected to the valve body through a bolt.
[0009] As a further scheme of the utility model: wherein, when the valve cover closes the valve body, the plug body is in interference fit with the inner wall of the valve body.
[0010] As a further scheme of the utility model: wherein, the insert is a plurality of insertion rods, and the plurality of insertion rods are filled and distributed in the area corresponding to the water drain hole on one side of the plug body.
[0011] As a further scheme of the utility model: wherein, a flange is arranged on the valve body and located outside the mesh cover.
[0012] As a further scheme of the utility model: wherein, a sealing ring is arranged on the side of the flange facing the valve cover.
[0013] Due to the adoption of the above technical scheme, the utility model has the following beneficial effects:
[0014] The water drain valve for the flood prevention door provided by the utility model can drive the plug body to separate from the water drain hole by opening the valve cover, so that the water flow is discharged from the valve body through the mesh cover and the plurality of water drain holes. Since the structure of the mesh cover and the plurality of water drain holes can effectively disperse the water flow impact force, the flow rate and pressure of the water flow discharged from a single water drain hole are reduced, so that the water pressure of the accumulated water on the flood prevention door can be reduced. After the drainage is completed, the valve cover can be closed to form the interference fit between the plug body and the inner wall of the valve body, so as to seal the water drain hole. The mesh cover can not only disperse the water flow impact force, but also filter out the large-size sundries entrained in the water flow, so as to prevent the water drain hole from being blocked. Even if the water drain hole is blocked by small-size sundries, the water drain hole can be dredged by repeatedly closing and opening the valve cover and inserting the insert into the water drain hole for multiple times.
[0015] Compared with the prior art, the utility model not only can reduce the water pressure of the accumulated water on the flood prevention door, but also can prevent the water drain hole from being blocked. BRIEF DESCRIPTION OF DRAWINGS

[0023] In the following, only certain exemplary embodiments are described simply. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the following description is considered to be exemplary in nature rather than limiting.
[0024] Reference should be made to Figures 1-4 In an embodiment of the water release valve for the floodgate according to the present application, the water release valve for the floodgate comprises a valve body 1, a mesh cover 2 and a valve cover 3:
[0025] The valve body 1 is in the shape of a cylinder and is arranged to pass through the floodgate 6. The valve body 1 has a plurality of circular water release holes 11 at one end. Water flow on one side of the floodgate 6 can be discharged through the water release holes 11. The mesh cover 2 covers all the water release holes 11 and is connected to the valve body 1. On one hand, the mesh cover 2 prevents large-sized impurities (such as leaves, household garbage, etc.) from passing through the water release holes 11. On the other hand, the mesh cover 2 can also reduce the impact of accumulated water on the floodgate 6. The valve cover 3 covers the other end of the valve body 1. The valve cover 3 has a plug body 31. The plug body 31 has a plurality of plugs 32 corresponding to the water release holes 11. When the valve cover 3 is closed, the plug body 31 is arranged in the valve body 1 and seals all the water release holes 11. The plugs 32 are inserted into the corresponding water release holes 11. In this way, when the water release holes 11 are blocked by small-sized impurities such as silt, the plugs 32 can be used to dredge the water release holes 11 by opening and closing the valve cover 3.
[0026] It should be noted that, in order to avoid large-sized impurities completely covering the mesh cover 2 and causing difficulty in water discharge, the surface area of the mesh cover 2 is preferably designed to be large enough, and the impurities covering the outer surface of the mesh cover 2 should be cleaned regularly.
[0027] Specifically, the plurality of water drainage holes 11 can be the same in shape and size, and uniformly distributed on the end face of the valve body 1, so that the water flow can be uniformly discharged from the water drainage holes 11, avoiding the concentration or retention of water flow in a local area, thereby dispersing the impact force of the water flow, reducing the impact of the water flow on the water drainage valve and the surrounding structure, and also reducing the possibility of accumulation of sundries in a certain area and the risk of blockage.
[0028] Specifically, the upper end of the valve cover 3 is rotatably connected to the valve body 1 through a hinge, and the lower end of the valve cover 3 is detachably connected to the valve body 1 through a bolt. When in use, the valve cover 3 is opened by turning upward, so that the water flow is smoothly discharged. When the valve cover 3 is loosened, the valve cover 3 can be automatically closed under the action of its own gravity, and then locked by the bolt. Of course, the upper end of the valve cover 3 can also be detachably connected to the valve body 1 through a bolt, and the lower end of the valve cover 3 can be rotatably connected to the valve body 1 through a hinge. In this way, when the bolt is loosened, the valve cover 3 can be automatically opened under the action of its own gravity, and the drainage is more convenient.
[0029] Specifically, the plug body 31 can be made of rubber, and a gap is left between the upper and lower sides of the plug 32 and the inner wall of the water drainage hole 11 and between the upper and lower sides of the plug body 31 and the inner circumferential wall of the valve body 1, so that the plug 32 and the plug body 31 can be smoothly inserted into the water drainage hole 11 and the valve body 1, respectively, when the valve cover 3 is closed. The length of the plug body 31 is greater than the length of the inner cavity of the valve body 1, so that the plug body 31 can form an interference fit with the inner end wall of the valve body 1 when the valve cover 3 is closed, thereby sealing the water drainage hole 11.
[0030] Specifically, the plug 32 can be provided as a plurality of insertion rods, which are filled and distributed in the area of the plug body 31 corresponding to the water drainage hole 11. One end of the insertion rod is preferably a sharp end, so that the plug 32 can more easily dredge the blocked silt when inserted into the water drainage hole 11.
[0031] Specifically, the valve body 1 is welded with a flange 4 located outside the mesh cover 2. When the valve body 1 is installed, the valve body 1 is arranged through the anti-flooding door 6, and the valve body 1 is fixed on the anti-flooding door 6 through the bolt holes of the flange 4 by using the bolts.
[0032] More specifically, a sealing ring 5 can be provided on the side of the flange 4 facing the valve cover 3, to prevent water flow from the gap between the flange 4 and the anti-flooding door 6, thereby enhancing the sealing performance.
[0033] The use method or working principle of the utility model is as follows:
[0034] When the water accumulated behind the flood prevention door 6 needs to be drained, the bolt is loosened and the valve cover 3 is opened, the valve cover 3 drives the plug body 31 to be separated from the water drain hole 11, so that the water flows out from the valve body 1 through the mesh cover 2 and the plurality of water drain holes 11, since the structure of the mesh cover 2 and the plurality of water drain holes 11 can effectively disperse the water flow impact force, reduce the flow rate and pressure of the water flow discharged from a single water drain hole 11, thus the water pressure on the flood prevention door 6 can be reduced; after the water is drained, the valve cover 3 is closed and the bolt is tightened, so that the plug body 31 is in interference fit with the inner end wall of the valve body 1, thereby sealing the water drain hole 11.
[0035] During the flood or heavy rain, a large amount of sundries may be entrained in the water flow, the mesh cover 2 can prevent the large size sundries (such as leaves, household garbage, etc.) entrained in the water flow from passing through the water drain hole 11, so as to avoid causing blockage. When the small size sundries such as silt in the water flow are accumulated too much to cause blockage of the water drain hole 11, the valve cover 3 can be repeatedly closed and opened, and the plug-in part 32 is inserted into the water drain hole 11 for multiple times to dredge.
[0036] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
