Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, and in particular to a gate valve that is easy to be electrically adjusted. Background Technology

[0002] A gate valve is a common control valve used in pipeline systems, primarily for regulating or cutting off fluid flow in pipelines. It achieves precise flow control by rotating the valve core to change the opening of the fluid passage. Gate valves have a simple structure, typically consisting of a valve body, valve seat, valve stem, valve cover, and handwheel. Their working principle involves the up-and-down movement of the valve stem, causing the valve core to come into close contact with or completely separate from the valve seat, thereby effectively opening or closing the fluid passage.

[0003] Gate valves are extremely common in daily use. Existing electrically regulated gate valves can only open by moving up and down, and cannot gradually open, which makes it impossible for the gate valve to control the flow and thus reduces the working performance of the gate valve.

[0004] Therefore, there is an urgent need to provide a shut-off valve that is easy to electrically regulate in order to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a shut-off valve that is easy to be electrically adjusted.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing a shut-off valve that is easy to be electrically adjusted, including a valve body, a valve cover fixedly connected to the top of the valve body, and connecting bodies installed on both sides of the valve body;

[0007] A rotation control mechanism is installed on the top of the valve cover, and an adjustment mechanism is installed inside the valve body.

[0008] The present invention is further configured such that: the rotation control mechanism includes a support frame fixedly connected to the top of the valve cover, a threaded rod rotatably connected inside the support frame, a rotating disk fixedly connected to the top of the threaded rod, a partition fixedly connected to the inner wall of the valve body, a valve plate fixedly connected to the bottom of the threaded rod, the outer wall of the valve plate fitting against the partition, and a through hole provided at the center of the partition.

[0009] With the above technical solution, the through hole is mainly used to allow fluid flow, ensuring the normal function of the shut-off valve. After the shut-off valve is installed, the rotary control mechanism can be used to control the water flow and prepare the overall operating state of the water flow. The operator will control the shut-off valve according to the water flow size to ensure that the shut-off valve can maintain its normal operating state and structure. Specifically, after the water flows into the valve body through the connecting body, the operator can manually rotate the rotary disc to drive the threaded rod to rotate, which will then drive the valve plate to rise or fall until the valve plate is in contact with or separated from the partition. Then, the shut-off valve can be kept in the shut-off state by rotating the rotary disc.

[0010] The present invention is further configured such that: the adjusting mechanism includes a motor fixedly connected to the top of the rotating disk, a drive shaft fixedly connected to the output end of the motor, a circular plate fixedly connected to the bottom of the drive shaft, a connecting rod rotatably connected to the bottom of the circular plate, a circular ring rotatably connected to the other end of the connecting rod, multiple columns at the bottom of the circular ring penetrating an arc-shaped plate, a first arc-shaped groove being formed at the bottom of each of the multiple arc-shaped plates, a second arc-shaped groove being formed in the annular portion of the valve plate, a column at the top of the annular portion of the valve plate being slidably connected to the first arc-shaped groove, and multiple columns at the bottom of the circular ring being slidably connected to the corresponding second arc-shaped groove.

[0011] Through the above technical solution, based on the control of the rotary control mechanism, the original operating state of the shut-off valve can be changed by the adjustment mechanism. Electric adjustment allows the shut-off valve to change the diameter of the through hole during use, and the flow rate will change with the change of diameter. On this basis, the shut-off valve not only changes the original manual adjustment, but also allows the flow rate of the shut-off valve to be controlled more precisely. Specifically, starting the motor at the top of the rotary disk drives the circular plate on the drive shaft to rotate. Since the edge ring of the circular plate is connected to the connecting rod, it will pull the ring to rotate, which in turn drives the corresponding arc plate to rotate. Since the first arc groove on the arc plate forms a certain limit with the column on the valve plate, the arc plate expands outward from a fixed point, thereby changing the diameter of the through hole and controlling the flow rate under electric adjustment.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By designing a rotation control mechanism and an adjustment mechanism, this utility model allows operators to not only manually rotate and adjust the stop valve when it is in use, but also to control the flow rate of the stop valve electrically. This enables the flow rate through the stop valve to be electrically adjusted, thereby enhancing the performance of the stop valve.

[0014] 2. This utility model, through the design of an adjustment mechanism, can control the diameter of the gate valve's inlet, thereby controlling the flow rate of the gate valve and making the use of the gate valve more convenient. Attached Figure Description

Detailed Implementation

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] Please see Figures 1-5A shut-off valve for easy electric adjustment includes a valve body 1, a valve cover 2 fixedly connected to the top of the valve body 1, connecting bodies 3 installed on both sides of the valve body 1, and a rotary control mechanism 4 installed on the top of the valve cover 2. The rotary control mechanism 4 includes a support frame 401 fixedly connected to the top of the valve cover 2, a threaded rod 402 rotatably connected inside the support frame 401, a rotating disk 403 fixedly connected to the top of the threaded rod 402, a partition 404 fixedly connected to the inner wall of the valve body 1, and a valve plate 405 fixedly connected to the bottom of the threaded rod 402. The outer wall of the valve plate 405 fits against the partition 404, and a through hole is provided at the center of the partition 404. During use, the through hole is mainly used for fluid flow to ensure... To ensure the normal operation of the shut-off valve, after the shut-off valve is installed, the rotary control mechanism 4 can be used to control the water flow and prepare the overall operation of the water flow. The operator will control the shut-off valve according to the size of the water flow to ensure that the shut-off valve can maintain its normal operation and structure. Specifically, when the water flows into the valve body 1 through the connecting body 3, the operator can manually rotate the rotary disc 403 to drive the threaded rod 402 to rotate, which will then drive the valve plate 405 to rise or fall until the valve plate 405 is in contact with or separated from the partition 404. Then, the shut-off valve can be kept in the shut-off state by rotating the rotary disc 403.

[0023] like Figures 3-5As shown, an adjusting mechanism 5 is installed inside the valve body 1. The adjusting mechanism 5 includes a motor 501 fixedly connected to the top of the rotating disk 403. A drive shaft 502 is fixedly connected to the output end of the motor 501. A circular plate 503 is fixedly connected to the bottom of the drive shaft 502. A connecting rod 504 is rotatably connected to the bottom of the circular plate 503. A circular ring 505 is rotatably connected to the other end of the connecting rod 504. Multiple columns at the bottom of the circular ring 505 pass through arc-shaped plates 506. The bottom of each arc-shaped plate 506 has a first arc-shaped groove 507. The annular portion of the valve plate 405 has a second arc-shaped groove 508. The columns at the top of the annular portion of the valve plate 405 are slidably connected to the first arc-shaped groove 507, and the multiple columns at the bottom of the circular ring 505 are slidably connected to the corresponding second arc-shaped groove 508. Based on the control of the rotation control mechanism 4, the adjusting mechanism 5 can be used to change the original operating state of the shut-off valve. Electric adjustment allows the gate valve to change the diameter of its through-hole during use, thus changing the flow rate accordingly. This not only eliminates the need for manual adjustment but also enables more precise flow control. Specifically, the motor 501 on top of the rotating disk 403 drives the circular plate 503 on the drive shaft 502 to rotate. Since the edge ring of the circular plate 503 is connected to the connecting rod 504, it pulls the ring 505 to rotate, which in turn drives the corresponding arc-shaped plate 506 to rotate. Because the first arc-shaped groove 507 on the arc-shaped plate 506 forms a certain limit with the column on the valve plate 405, the arc-shaped plate 506 expands outward from a fixed point, thereby changing the diameter of the through-hole and controlling the flow rate through electric adjustment.

[0024] When this utility model is in use, after the shut-off valve is installed, when water flows into the valve body 1 through the connecting body 3, the operator can manually rotate the rotating disk 403 to drive the threaded rod 402 to rotate, which will then drive the valve plate 405 to rise or fall until the valve plate 405 is in contact with or separated from the partition 404. Then, the shut-off valve can be kept in the shut-off state by rotating the rotating disk 403. Then, the motor 501 at the top of the rotating disk 403 is started to drive the circular plate 503 on the drive shaft 502 to rotate. Since the edge ring of the circular plate 503 is connected to the connecting rod 504, it will pull the ring 505 to rotate, which will drive the corresponding arc plate 506 to rotate. Since the first arc groove 507 on the arc plate 506 and the column on the valve plate 405 form a certain limit, the arc plate 506 unfolds outward from a fixed point. At this point, the movement ends.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
