[0004] 1. The thickness of the steel plate cannot be flexibly adjusted to meet welding requirements;

[0005] 2. The through hole ring and the blind hole ring should be welded together through the connecting plate. Since the distribution of the reinforcing ribs inside the blind hole plate greatly enhances the rigidity of this ring, and the through hole ring is light in weight and simple in structure, the rigidity of the two rings is very different, and the deformation caused by welding with adjacent plates is also quite different, which will cause a lot of man-hours for the flatness adjustment of the entire valve plate in the later stage. In most cases, it will also cause different degrees of difficulty due to the level of the welding workers, and it is not easy to level.

[0006] 3. The valve body is a stable and reinforced welded part, and the valve plate is also a very stable and reinforced welded part. This will cause the problem that when the valve body seat and the valve plate sealing ring do not fit during the later assembly process, there is no way to remedy the problem.

DETAILED DESCRIPTION

[0034] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] Example: Figure 1-Figure 7 As shown, this embodiment provides a valve plate anti-deformation connection structure of a blind plate valve, including a blind hole ring 1, a through hole ring 2, a first intermediate connecting plate 3 and a second intermediate connecting plate 4. The blind hole ring 1 has a sealing plate 11 inside thereof for closing the blind plate valve, and the outer side wall of the blind hole ring 1 is fixedly provided with a first upper arc plate 12 and a first lower arc plate 13; the through hole ring 2 is used for allowing the fluid medium to pass through the valve body of the blind plate valve, and the outer side wall of the through hole ring 2 is fixedly provided with a second upper arc plate 21 and a second lower arc plate 22; the first intermediate connecting plate 3 is rotatably mounted on the valve body, and one side of its lower part is fixedly connected to the first upper arc plate 12 by bolts, and the other side of its lower part is fixedly connected to the second upper arc plate 21 by bolts; the second intermediate connecting plate 4 is fixedly connected to the first lower arc plate 13 by bolts on one side, and fixedly connected to the second lower arc plate 22 by bolts on the other side.

[0036] This arrangement adopts a detachable split design, which makes it easy to adjust the thickness of the plate and avoids deformation caused by welding. There is no need to adjust the flatness of the valve plate in the later stage, which reduces the workload, saves labor costs, facilitates remediation in the later stage of assembly, and facilitates transportation and processing.

[0037] The valve plate anti-deformation connection structure of a blind plate valve of this embodiment also includes a first bottom connecting plate 14, a second bottom connecting plate 23 and a connecting member 5. The first bottom connecting plate 14 is integrally connected to the lower outer side of the blind hole ring 1; the second bottom connecting plate 23 is integrally connected to the lower outer side of the through hole ring 2; one end of the connecting member 5 is fixedly connected to the first bottom connecting plate 14 by bolts, and the other end of the connecting member 5 is fixedly connected to the second bottom connecting plate 23 by bolts.

[0038] In this arrangement, the first bottom connecting plate 14, the second bottom connecting plate 23, the blind hole ring 1 and the through hole ring 2 are detachable and split, which is convenient for adjusting the thickness of the plate and avoiding deformation caused by welding. There is no need to adjust the flatness of the valve plate at a later stage, which reduces the workload, saves labor costs, facilitates remediation at the later stage of assembly, and facilitates transportation and processing.

[0039] In the valve plate anti-deformation connection structure of a blind plate valve of this embodiment, the first bottom connecting plate 14 and the second bottom connecting plate 23 are symmetrical about the center line of the first middle connecting plate 3. This arrangement has beautiful shape and is easy to process.

[0040] In the valve plate deformation prevention connection structure of a blind plate valve of the present embodiment, a sealing plate 11 is provided in the blind hole ring 1, a plurality of first reinforcing ribs 15 are fixedly arranged in the blind hole ring 1, and a plurality of second reinforcing ribs 24 are fixedly arranged in the through hole ring 2. In this way, the second reinforcing ribs 24 are arranged in the through hole ring 2, which improves the rigidity of the through hole ring 2 and reduces the deformation of the through hole ring 2, so that the deformation of the through hole ring 2 and the blind hole ring 1 are not much different, and the adjustment of the through hole ring 2 in the later stage is reduced.

[0041] In the anti-deformation connection structure of the valve plate of a blind plate valve of this embodiment, the first reinforcing ribs 15 in the blind hole ring 1 are arranged in the same manner as the second reinforcing ribs 24 in the through hole ring 2. This arrangement makes the connection mode of the blind hole ring 1 and the through hole ring 2 consistent, the rigidity strength is closer, and the deformation amount is less different.

[0042] In the valve plate anti-deformation connection structure of a blind plate valve of this embodiment, a plurality of first reinforcing ribs 15 are arranged in a grid shape in the blind hole ring 1, and a plurality of second reinforcing ribs 24 are arranged in a grid shape in the through hole ring 2. With such a configuration, the arrangement in a grid shape makes the through hole ring 2 evenly stressed when the fluid medium passes through the through hole ring 2, thereby reducing the deformation of the through hole ring 2 and extending the service life.

[0043] In the valve plate deformation prevention connection structure of a blind plate valve of this embodiment, the center lines of the first intermediate connecting plate 3 and the second intermediate connecting plate 4 coincide with each other, and the blind hole ring 1 and the through hole ring 2 are bilaterally symmetrical about the center line of the first intermediate connecting plate 3. This arrangement makes the external forces on the blind hole ring 1 and the through hole ring 2 evenly balanced, so that the deformation amounts of the blind hole ring 1 and the through hole ring 2 are relatively small.

[0044] In the valve plate deformation prevention connection structure of a blind plate valve of this embodiment, the connecting member 5 is a plate body, which is small in size and saves space.

[0045] In the valve plate deformation prevention connection structure of a blind plate valve of this embodiment, there are two connecting members 5, which are respectively located at the front side and the rear side of the two bottom connecting plates, thereby improving the connection stability of the first bottom connecting plate 14 and the second bottom connecting plate 23.

[0046] In the valve plate anti-deformation connection structure of a blind plate valve of this embodiment, a connecting ring plate 111 is integrally provided on the outer circumference of the sealing plate 11, a sealing ring 6 is provided between the outer wall of the connecting ring plate 111 and the inner wall of the blind hole ring 1, and the connecting ring plate 111 is fixedly connected to the blind hole ring 1 by bolts 7. The sealing plate 11 and the blind hole ring 1 are designed in a split type, which is convenient for transportation and processing, and the sealing ring 6 is used to improve the sealing effect between the sealing plate 11 and the blind hole ring 1. A large deformation caused by welding the sealing plate 11 and the blind hole ring 1 is avoided. Optionally, the sealing plate 11 is separated from the first reinforcing rib 15 to avoid the connection of the sealing plate 11 increasing the deformation of the blind hole ring 1.

[0047] The valve plate anti-deformation connection structure of a blind plate valve of this embodiment has the following advantages:

[0048] 1. The thickness of the steel plate material of the valve plate has been improved, which can reduce the welding defects caused by incorrect welding methods or low welding workers when welding steel plates with too large a difference in thickness, greatly reduce the failure rate of the valve during the operation of the valve plate, and increase the service life of the valve.

[0049] 2. The through hole ring 2, the blind hole ring 1 and the middle connecting plate are first processed and formed, and then connected together with connecting bolts 7 to form a detachable and adjustable structure with a simple structure, avoiding welding deformation and improving the flatness of the entire valve plate.

[0050] 3. The structure of the valve plate adopts a detachable fixed connection method, which makes the valve plate a fine-tunable structure. The verticality of the valve plate can be adjusted within a certain range. When the valve plate is switched, it will not cause the valve plate to be unstable due to insufficient verticality, and the sealing structure of the valve plate will not collide with the valve body seat to damage the sealing structure. This greatly improves the service life of the valve.

[0051] 4. In the manufacturing process of the valve plate, due to the adjustment of the processing procedures, the difficulty of transporting large-size workpieces is reduced, an assembly line process can be formed, and production efficiency is improved.
