Description

Technical Field

[0001] The utility model specifically relates to a fluid material processing valve body structure. Background Art

[0002] CN1100583C discloses a fluid-solid contact device including a group of containers supported on a rotating disc conveyor, each container having a discharge pipe and a single valve for controlling the supply and discharge of fluid. The valve includes a fixed annular disc having a lower flat surface forming a disc valve surface and a group of pipes, and a rotatable annular plate having an upper flat surface forming a flat valve surface and a group of holes forming valve holes on the flat valve surface. The flat valve surface is brought into contact with the disc valve surface under pressure. In order to obtain the necessary valve plate sealing force, the technical solution is provided with a pressurized fluid source on the upper part of the disc valve surface, which will result in the use of very heavy valve body materials and the flow channel in the valve must be set to an L-shaped path with greater fluid resistance. This structure also brings three unavoidable defects: 1. The external pipe must use an expensive and unreliable hose to enter and exit the side of the cylinder; 2. The action device of the fluid source for pressurized sealing must be arranged inside the valve body, which will result in the difficulty of maintaining the device in an actual industrial application environment; 3. This structure has a high cost in equipment manufacturing. Utility Model Content

[0003] The utility model aims to provide a fluid material processing valve body structure.

[0004] The technical solution of the utility model is as follows:

[0005] A fluid material processing valve body structure comprises a first valve body, a second valve body, at least one first tube sheet, at least one second tube sheet, at least one sealing plate and at least one sealing mechanism.

[0006] The first valve body has a plurality of first distribution pipelines, and the first tube plate is provided with a plurality of first ingredient distribution pipelines adapted to the plurality of first distribution pipelines; the second valve body has a plurality of second distribution pipelines, and the second tube plate is provided with a plurality of second ingredient distribution pipelines adapted to the plurality of second distribution pipelines; the sealing plate is provided with a plurality of sealing through holes adapted to connect the plurality of first ingredient distribution pipelines and the plurality of second ingredient distribution pipelines;

[0007] The first valve body, at least one first tube sheet, at least one sealing plate, at least one second tube sheet and the second valve body are pressed and adapted in sequence by at least one sealing mechanism to form an end face seal, and the first valve body and at least one first tube sheet can be synchronously rotated relative to the second valve body and at least one second tube sheet.

[0008] In a preferred embodiment of the present invention, it also includes a main shaft, and the first valve body, the second valve body, at least one first tube sheet, at least one second tube sheet and at least one sealing plate are all installed on the main shaft, and the first valve body and at least one first tube sheet can be synchronously rotated relative to the second valve body and at least one second tube sheet with the main shaft as the rotation axis.

[0009] Further preferably, the second valve body and at least one second tube sheet are fixedly arranged relative to the main shaft.

[0010] More preferably, the first valve body rotates relative to the main shaft via an inner ring bearing mechanism.

[0011] Still further preferably, the first valve body rotates relative to the second valve body in an indexed manner via an outer ring bearing mechanism.

[0012] Further preferably, among the at least one sealing mechanism, each sealing mechanism includes at least one first hydraulic sealing mechanism and at least one second hydraulic sealing mechanism, at least one first hydraulic sealing mechanism is close to the main shaft and evenly arranged along the circumference of the main shaft, and at least one second hydraulic sealing mechanism is away from the main shaft and evenly arranged along the circumference of the second valve body.

[0013] More preferably, the at least one second hydraulic sealing mechanism is evenly arranged along the edge of the second valve body.

[0014] Further preferably, it also includes a base, the main shaft is mounted on the base, and the base is mounted on a bearing foundation.

[0015] In a preferred embodiment of the present invention, the plurality of first distribution pipelines are straight pipe-shaped and pass through two end surfaces of the first valve body; the plurality of second distribution pipelines are straight pipe-shaped and pass through two end surfaces of the second valve body.

[0016] The beneficial effects of the utility model are:

[0017] 1. The first valve body, at least one first tube sheet, at least one sealing plate, at least one second tube sheet and the second valve body in the utility model are pressed and adapted in sequence by at least one sealing mechanism to form an end face seal. The first valve body and at least one first tube sheet can be synchronously rotated relative to the second valve body and at least one second tube sheet. The structure is simple and the sealing effect is good.

[0018] 2. Each sealing mechanism in the utility model includes at least one first hydraulic sealing mechanism and at least one second hydraulic sealing mechanism. The at least one first hydraulic sealing mechanism is close to the center of the first valve body, and the at least one second hydraulic sealing mechanism is far away from the center of the first valve body, so that the end faces between the first valve body, at least one first tube sheet, at least one sealing plate, at least one second tube sheet and the second valve body can achieve end face sealing with uniform force, thereby improving the overall reliability of the equipment.

[0019] 3. The first valve body and the first tube sheet of the utility model can be separated and disassembled, the second valve body and the second tube sheet can be separated and disassembled, and the wear parts are limited to the second tube sheet and the sealing plate. When the wear limit is reached, there is no need to replace the first valve body and the second valve body, but only the second tube sheet and / or the sealing plate need to be replaced as needed, which greatly reduces the maintenance cost of the equipment.

[0020] 4. The first distribution pipelines and the second distribution pipelines of the utility model are all straight pipes and pass through the two end faces of the first valve body and the second valve body, so that the fluid flow resistance is low. At the same time, they are easy to maintain and have low manufacturing costs in conjunction with the sealing plate and at least one first hydraulic sealing mechanism and at least one second hydraulic sealing mechanism.

[0023] The technical solution of the present utility model is further illustrated and described below through specific implementation modes in combination with the accompanying drawings.

[0024] like Figure 1 and 2 As shown, a fluid material processing valve body structure includes a base 1, a main shaft 2, a first valve body 3, a second valve body 4, a first tube sheet 5, a second tube sheet 6, a sealing plate 7 and a sealing mechanism 8, the first valve body 3, the second valve body 4, the first tube sheet 5, the second tube sheet 6 and the sealing plate 7 are all installed on the main shaft 2, and the second valve body 4 and the second tube sheet 6 are fixedly arranged relative to the main shaft 2, the main shaft 2 is installed on the base 1, and the base 1 is installed on a bearing foundation;

[0025] The first valve body 3 has a plurality of straight first distribution pipelines 31 penetrating through its two end surfaces, and the first tube sheet 5 is provided with a plurality of first ingredient pipelines 51 adapted to the plurality of first distribution pipelines 31; the second valve body 4 has a plurality of straight second distribution pipelines 41 penetrating through its two end surfaces, and the second tube sheet 6 is provided with a plurality of second ingredient pipelines 61 adapted to the plurality of second distribution pipelines 41; the sealing plate 7 has a plurality of sealing through holes 71 adapted to connect the plurality of first ingredient pipelines 51 and the plurality of second ingredient pipelines 61; the straight first distribution pipelines 31 and the second distribution pipelines 41 mentioned above greatly reduce the fluid flow running resistance therein;

[0026] The first valve body 3, the first tube sheet 5, the sealing plate 7, the second tube sheet 6 and the second valve body 4 are pressed and adapted in sequence through the sealing mechanism 8 to form an end face seal, the first valve body 3 and the first tube sheet 5 are connected by bolts, and the second valve body 4 and the second tube sheet 6 are connected by bolts, so that the first valve body 3 and the first tube sheet 5 can be synchronously rotated relative to the second valve body 4 and the second tube sheet 6 with the main shaft 2 as the rotation axis so that different first distribution pipelines 31 can be connected to different second distribution pipelines 41 according to process requirements, wherein the first valve body 3 rotates relative to the main shaft 2 through the inner ring bearing mechanism 32, and the first valve body 3 rotates relative to the second valve body 4 through the outer ring bearing mechanism 33. The first valve body 3 and the first tube sheet 5 can be separated and disassembled by removing the bolts, and the second valve body 4 and the second tube sheet 6 can be separated and disassembled by removing the bolts. The wear parts are limited to the second tube sheet 6 and the sealing plate 7 which are relatively light in weight. When the wear limit is reached, there is no need to replace the heavy first valve body 3 and the second valve body 4, but only the light second tube sheet 6 and / or the sealing plate 7 need to be replaced as needed, which greatly reduces the maintenance cost of the equipment.

[0027] The sealing mechanism 8 includes a plurality of first hydraulic sealing mechanisms 81 (preferably driven by a cylinder) and a plurality of second hydraulic sealing mechanisms 82 (preferably driven by a cylinder). The plurality of first hydraulic sealing mechanisms 81 are close to the main shaft 2 and are evenly arranged along the circumference of the main shaft 2, so as to press the first valve body 3 and the first tube sheet 5 toward the sealing plate 7, the second tube sheet 6 and the second valve body 4; the plurality of second hydraulic sealing mechanisms 82 are away from the main shaft 2 and are installed on the edge of the second valve body 4, and are evenly arranged along the circumference of the second valve body 4, so as to pull the first valve body 3 and the first tube sheet 5 toward the sealing plate 7, the second tube sheet 6 and the second valve body 4. The first hydraulic sealing mechanism 81 and the second hydraulic sealing mechanism 82 cooperate with each other, so that the end faces between the first valve body 3, the first tube sheet 5, the sealing plate 7, the second tube sheet 6 and the second valve body 4 can achieve end face sealing with uniform force, thereby improving the overall reliability of the equipment.

[0028] The above is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the content of the specification should still fall within the scope covered by the present invention.
