Description

Technical Field

[0001] The present application relates to the technical field of valve bodies, and in particular to a ball valve with an embedded regulating device. Background Art

[0002] In mesh pipes, ball valves are often used as a measure to adjust the flow direction of water inside the mesh pipes or to cut off the water flow.

[0003] The ball valves currently used are mostly composed of a sphere disposed between two sections of pipes, with a through hole penetrating the sphere in the middle. By rotating the sphere 90 degrees, the through hole inside the sphere is no longer connected to the pipes on both sides, thereby realizing the process of cutting off the pipes on both sides.

[0004] The ball valves currently used are mostly simple opening and closing operations, but in some cases, the flow inside the pipeline needs to be adjusted. At this time, it is necessary to apply other components to achieve separate flow regulation, which is more troublesome. Utility Model Content

[0005] In order to achieve regulation of the flow rate inside a pipeline through a ball valve, the present application provides a ball valve with a built-in regulating device.

[0006] The ball valve with built-in regulating device provided in the present application adopts the following technical solution:

[0007] A ball valve with an embedded regulating device comprises a valve housing, one end of the valve housing is connected to a water inlet pipe, the other end of the valve housing is connected to a water outlet pipe, a sphere is provided inside the valve housing between the water inlet pipe and the water outlet pipe, a through hole is provided in the middle of the sphere, which passes through the sphere and can connect the water inlet pipe and the water outlet pipe, the opposite sides of the water inlet pipe and the water outlet pipe can abut against the sphere, and a flow limiting component for regulating the water flow passing through the through hole is provided inside the through hole of the sphere.

[0008] By adopting the above technical solution and setting a flow limiting component, the flow rate of water passing through the middle hole of the sphere can be adjusted by the flow limiting component, thereby reducing the phenomenon that the ball valve has difficulty in adjusting the flow rate of water passing through the ball valve hole.

[0009] Optionally, the current limiting assembly includes a current limiting block, a current limiting cylinder is sleeved on the outer side of the current limiting block, and the outer wall of the current limiting block is configured as an inclined surface which gradually inclines away from its own center line along a side close to the current limiting cylinder to a side away from the current limiting cylinder.

[0010] By adopting the above technical solution, when it is necessary to adjust the flow rate of water at the internal hole of the sphere, the flow limiting block is moved so that the gap between the flow limiting block and the flow limiting cylinder is changed, thereby realizing the process of adjusting the flow rate of water passing through the internal hole of the sphere.

[0011] Optionally, the current limiting block is fixedly connected to a current limiting rod on one side away from the current limiting cylinder, the current limiting rod has an external threaded sleeve with a connecting plate, and the outer wall of the connecting plate is fixedly connected to the hole wall of the internal through hole of the sphere.

[0013] Optionally, one side of the valve housing is connected to an adjusting tube, one end of the adjusting tube passes through the interior of the valve housing and abuts against the outer wall of the sphere and can be connected to the middle through hole of the sphere, and a sealing member for sealing the adjusting tube is provided inside the adjusting tube.

The main shaft is connected to a prompt component for limiting the position of the main shaft.

[0016] By adopting the above technical solution and providing a prompt component, the phenomenon that the ball rotates under the action of water flow when the ball rotates to an appropriate angle, thereby affecting the normal use of the valve body, is reduced.

[0017] Optionally, the prompt component includes a prompt plate fixedly connected to the end of the main shaft away from the sphere, the main shaft and the external rotation of the prompt plate are sleeved with the same prompt tube, a plurality of telescopic rods are slidably inserted on the side wall of the prompt plate, a plurality of prompt holes are opened on the side wall of the prompt tube, the center lines of some of the prompt holes are opened parallel to the center line of the water inlet pipe, and the center lines of the remaining prompt holes are opened perpendicular to the center line of the water inlet pipe.

[0018] By adopting the above technical solution, when the main shaft drives the ball to rotate, the main shaft drives the prompt plate to rotate.

The water outlet pipe is fixedly connected to one end of the sphere with a water outlet sealing ring, and the water outlet sealing ring abuts the outer wall of the sphere.

[0022] By adopting the above technical solution and providing a water inlet sealing ring and a water outlet sealing ring, the phenomenon of water flowing out from between the water inlet pipe or the water outlet pipe and the side wall of the sphere during actual use is reduced.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1 -Attached Figure 2 This application is described in further detail.

[0030] The present application embodiment discloses a ball valve with an embedded regulating device, referring to Figure 1 and Figure 2, including a valve housing 1, which is set to be a hollow cylindrical shape, one end of the valve housing 1 is connected to a water inlet pipe 2, and the other end of the valve housing 1 away from the water inlet pipe 2 is connected to a water outlet pipe 3, and the inner wall of the water inlet pipe 2 near the water outlet pipe 3 is fixedly connected to a water inlet disc spring 21, and the water inlet disc spring 21 is set to be inclined in an annular shape and is gradually inclined from a side close to the water outlet pipe 3 to a side away from the water outlet pipe 3 to a side close to the inner wall of the water inlet pipe 2 and is fixedly connected to the inner wall of the water inlet pipe 2. The end of the water inlet pipe 2 connected to the water inlet disc spring 21 is fixedly connected to a water inlet sealing ring 22 fixedly connected to the water inlet disc spring 21.

[0031] A water outlet disc spring 31 is fixedly connected to the inner wall of the water outlet pipe 3 at one end close to the water inlet pipe 2. The water outlet disc spring 31 is arranged in an inclined ring shape and is arranged along a side close to the water inlet pipe 2 to a side away from the water inlet pipe 2 and gradually inclined to a side close to the inner wall of the water outlet pipe 3 and fixedly connected to the inner wall of the water outlet pipe 3. A water outlet sealing ring 32 fixedly connected to the water outlet disc spring 31 is fixedly connected to the end of the water outlet pipe 3 connected to the water outlet disc spring 31.

[0032] A sphere 4 is provided in the middle of the water inlet sealing ring 22 and the water outlet sealing ring 32 , and the sphere 4 and the side walls thereof abut against the side walls of the adjacent water inlet sealing ring 22 and the water outlet sealing ring 32 .

[0033] A through hole is provided in the middle of the sphere 4, and the through hole can simultaneously connect the water inlet pipe 2 and the water outlet pipe 3. A flow limiting component 5 is provided inside the through hole of the sphere 4, and the flow limiting component 5 can limit the flow of water passing through the middle through hole of the sphere 4.

[0034] By setting the flow limiting component 5, the flow through the middle hole of the ball 4 can be limited, so that the flow of water passing through the ball valve can be limited between the operations of opening and closing the ball valve, so that the valve body can adapt to more application scenarios.

[0035] The current limiting assembly 5 includes a current limiting block 51 located inside the through hole of the sphere 4. The current limiting block 51 is set to be conical, and the center line of the current limiting block 51 is set parallel to the center line of the through hole of the sphere 4. A current limiting cylinder 52 is sleeved on the outer side of the current limiting block 51, and the outer wall of the current limiting cylinder 52 is fixedly connected to the inner wall of the through hole of the sphere 4, and the inner wall of the current limiting cylinder 52 is set to be an inclined surface parallel to the outer wall of the current limiting block 51. One end of the current limiting block 51 away from the current limiting cylinder 52 is fixedly connected to a current limiting rod 53, and the external thread of the current limiting rod 53 is sleeved with a connecting plate 54, the outer wall of the connecting plate 54 is fixedly connected to the inner wall of the through hole of the sphere 4, and the side wall of the connecting plate 54 is provided with a plurality of holes penetrating the side wall of the connecting plate 54.

[0036] The side wall of the valve housing 1 is penetrated and connected with an adjusting tube 55, and one end of the adjusting tube 55 inserted into the valve housing 1 abuts against the ball 4 and can be connected with the through hole of the ball 4. A blocking block 551 for blocking the adjusting tube 55 is provided inside the adjusting tube 55. The adjusting tube 55 is arranged perpendicular to the water inlet pipe 2.

[0037] When the sphere 4 is rotated so that the internal through hole of the sphere 4 is connected to the regulating tube 55, the blocking block 551 is taken out from the regulating tube 55, and then the flow limiting rod 53 is rotated. The flow limiting rod 53 drives the connected flow limiting block 51 to move during the rotation, so that the gap between the flow limiting block 51 and the flow limiting cylinder 52 can be adjusted, and then when the sphere 4 is rotated so that the through hole of the sphere 4 is connected to the water inlet pipe 2 and the water outlet pipe 3, the flow rate of water passing through the through hole of the sphere 4 can be adjusted.

[0038] The upper side of the ball 4 is fixedly connected with a main shaft 6, and one end of the main shaft 6 away from the ball 4 penetrates the side wall of the valve housing 1 and is rotatably connected to the side wall of the valve housing 1. One end of the main shaft 6 penetrating the side wall of the valve housing 1 is connected with a prompt component 7, which is used to limit the rotation of the main shaft 6.

[0039] By setting up the prompt component 7, when the ball 4 is driven to rotate by the main shaft 6 so that the through hole of the ball 4 is in a position connected to the water inlet pipe 2 or the regulating pipe 55, the rotation of the main shaft 6 can be limited by the prompt component 7, so that the ball 4 can be more stably located in the current position.

[0040] The flow limiting assembly 5 includes a prompting plate 71 fixedly connected to the end of the main shaft 6 away from the ball 4, and the main shaft 6 and the prompting plate 71 are rotatably sleeved with a prompting tube 72, and the lower end side wall of the prompting tube 72 is fixedly connected to the outer wall of the valve housing 1. The side walls of the main shaft 6 and the prompting plate are both rotatably abutted against the inner wall of the prompting tube 72.

[0041] The outer wall of the prompt plate 71 is slidably plugged with a plurality of telescopic plug rods 73, and each telescopic plug rod 73 can be plugged into the inner wall of the prompt plate 71 and removed from the inside of the prompt plate 71. A plurality of prompt holes 721 penetrating the prompt tube 72 are provided on the side wall of the prompt tube 72 close to the prompt plate 71. In this embodiment, two telescopic plug rods 73 are arranged opposite to each other, and four prompt holes 721 are arranged, wherein the center lines of two prompt holes 721 are arranged parallel to the center line of the water inlet pipe 2, and the center lines of the remaining two prompt holes 721 are arranged perpendicular to the center line of the water inlet pipe 2, and the four prompt holes 721 are evenly distributed around the side wall of the prompt tube 72. Two telescopic plug rods 73 can be simultaneously plugged into two oppositely opened prompt holes 721.

[0042] During the process of rotating the main shaft 6, the main shaft 6 drives the prompt disk 71 to rotate, and during the rotation of the prompt disk 71, the connected telescopic rod 73 is driven to rotate. When the main shaft 6 drives the ball 4 to rotate to the appropriate position, the telescopic rod 73 connected to the side wall of the prompt disk 71 is inserted into the adjacent prompt hole 721, thereby realizing the limitation of the position of the main shaft 6.

[0043] A pointer 711 is fixedly connected to the top wall of the prompt plate 71 .

[0044] By setting the pointer 711, the direction of the current through hole inside the sphere 4 can be indicated by the pointer 711, so that the staff can have a clearer understanding of the current position of the sphere 4.

[0045] The implementation principle of a ball valve with an embedded regulating device in an embodiment of the present application is: when it is necessary to adjust the flow of water passing through the middle hole of the ball 4, the prompt disk 71 is rotated, and the prompt disk 71 drives the main shaft 6 to rotate, and the ball 4 is driven by the main shaft 6 to rotate to a position where the through hole of the ball 4 is connected to the regulating tube 55, and the end of the flow limiting rod 53 away from the flow limiting block 51 is arranged toward the regulating tube 55.

[0046] Then, the blocking block 551 is taken out and the limiting rod 53 is rotated to adjust the position of the limiting block 51, thereby adjusting the flow rate of water passing through the middle hole of the sphere 4 when the sphere 4 is rotated to connect the water inlet pipe 2 and the water outlet pipe 3.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
