Abstract
Description
Technical Field
[0001] This utility model relates to the field of flow regulating valve technology, and in particular to a variable flow regulating valve. Background Technology
[0002] Flow control valves, also known as self-operated flow control valves, flow balancing valves, or static balancing valves, are intuitive and simple flow regulation and control devices widely used in various pipeline transportation applications. However, traditional flow control valves typically use a rotary valve stem to control the flow, requiring multiple turns of the stem, which is time-consuming and labor-intensive. Furthermore, corrosion of the stem can make it difficult to turn, significantly impacting the valve's usability. To address these issues, we propose a variable flow control valve. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in turning traditional rotary control valves and the difficulty in turning the valve stem when rust occurs. Therefore, a variable flow control valve is proposed.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A variable flow regulating valve includes a valve body with connection ports fixedly connected to both ends. A valve seat is fixedly mounted on the valve body, and a valve plate is slidably mounted inside the valve seat. The valve plate slidably extends through the inner wall of the valve seat into the valve body. Two side plates are symmetrically fixedly mounted on the inner wall of the valve body. Both side plates are arc-shaped and fit against the interior of the valve body, and are located on both sides of the valve plate. A receiving groove corresponding to the valve plate is opened on the valve seat, and the valve plate is slidably mounted in the receiving groove. A telescopic mechanism corresponding to the valve plate is provided in the receiving groove, and a limiting mechanism corresponding to the valve plate is also provided in the receiving groove.
[0006] Preferably, the telescopic mechanism includes a first pull rod, the side wall of the valve plate away from the opening of the storage groove is connected to the inner wall of the storage groove through a first spring, the first pull rod is fixedly disposed on the side wall of the valve plate near the first spring, and the first pull rod is slidably disposed through the upper wall of the valve seat, and a first pull handle is fixedly connected to the end of the first pull rod away from the valve plate.
[0007] Preferably, the limiting mechanism includes a locking block, and a telescopic groove corresponding to the locking block is provided on the side wall of the storage slot near the opening. The locking block is slidably disposed in the telescopic groove, and the locking block is connected to the inner wall of the telescopic groove by a second spring. Several locking slots corresponding to the locking block are arranged side by side on one side wall of the valve plate. The side wall of the locking block near the opening of the storage slot is inclined. The locking block is also provided with a corresponding pulling mechanism.
[0008] Preferably, the pulling mechanism includes a second pull rod, which is fixedly disposed on the side wall of the block near the second spring, and the second pull rod slides through the side wall of the valve seat. A second handle is also fixedly connected to the end of the second pull rod away from the block.
[0009] Preferably, a sealing sleeve is also fixedly fitted on the outer wall of the valve plate, and a plurality of slots corresponding to the slots are opened on one side wall of the sealing sleeve.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting two side plates, the arc surfaces on both sides of the valve body are blocked, making it convenient to control the flow rate by adjusting the extension length of the valve plate. The second pull rod controls the locking block; pulling the second pull rod causes the locking block to retract into the telescopic groove, thereby releasing the restriction and fixation of the valve plate. Under the action of the first spring, the valve plate is pushed out, thus completely blocking the valve body and achieving valve closure. The locking block restricts and fixes the valve plate. By pulling the valve plate upward with the first pull rod, the locking block can be inserted into different slots in sequence, allowing the valve plate to extend to different lengths to block the valve body, thereby achieving flow rate regulation. The sealing sleeve prevents moisture from entering the receiving groove and causing corrosion that affects the use of the valve. Attached Figure Description

Two side plates 5 are symmetrically fixedly mounted on the inner wall of the valve body 1, both side plates 5 being arc-shaped and fitting against the interior of the valve body 1, and located on both sides of the valve plate 10. A receiving groove 8 corresponding to the valve plate 10 is opened on the valve seat 3, and the valve plate 10 is slidably mounted in the receiving groove 8. A telescopic mechanism corresponding to the valve plate 10 is provided in the receiving groove 8, and the telescopic mechanism includes a first pull rod 6. The end of the valve plate 10 away from the opening of the receiving groove 8 is... The valve plate 10 is connected to the inner wall of the storage groove 8 via a first spring 9. A first pull rod 6 is fixedly mounted on the side wall of the valve plate 10 near the first spring 9, and the first pull rod 6 slides through the upper wall of the valve seat 3. A first pull handle 7 is fixedly connected to the end of the first pull rod 6 away from the valve plate 10. The storage groove 8 is also provided with a limiting mechanism corresponding to the valve plate 10. The limiting mechanism includes a locking block 13. A telescopic groove 14 corresponding to the locking block 13 is opened on the side wall of the storage groove 8 near the opening. The locking block 13 is slidably mounted in the telescopic groove 14, and the locking block 13 is connected to the inner wall of the telescopic groove 14 via a second spring 15. Several locking slots 11 corresponding to the locking blocks 13 are arranged side by side on one side wall of the valve plate 10.

Several slots corresponding to the locking slot 11 are opened on one side wall of the sealing sleeve 4. By setting two side plates 5, the arc surfaces on both sides of the valve body 1 are blocked, facilitating flow control by adjusting the vertical extension length of the valve plate 10. The second pull rod 16 controls the locking block 13. Pulling the second pull rod 16 causes the locking block 13 to retract into the telescopic groove 14, thereby releasing the restriction and fixation on the valve plate 10. Under the action of the first spring 9, the valve plate 10 is pushed out, thus completely blocking the valve body 1 and closing the valve. The locking block 13 restricts and fixes the valve plate 10. By pulling the valve plate 10 upward with the first pull rod 6, the locking block 13 can be inserted into different slots 11 in sequence, allowing the valve plate 10 to extend to different lengths to block the valve body 1, thereby regulating the flow rate. The sealing sleeve 4 prevents moisture from entering the receiving groove 8 and causing corrosion that affects the use of the valve.
[0018] In this invention, when using the valve for flow control, pulling the second lever 16 will cause the locking block 13 to retract into the telescopic groove 14, thereby releasing the restriction and fixation on the valve plate 10. Under the action of the first spring 9, the valve plate 10 is pushed out, thereby completely blocking the valve body 1 and thus closing the valve. By setting the locking block 13, the restriction and fixation of the valve plate 10 is achieved. By pulling the valve plate 10 upward by the first lever 6, the locking block 13 can be inserted into different slots 11 in sequence, so that the valve plate 10 can extend to different lengths to block the valve body 1, thereby achieving flow regulation.
