Description

Technical Field

[0001] This utility model relates to flow gate technology, specifically an automatic flow regulating gate device. Background Technology

[0002] The gate valve is the control center for pipeline and hydraulic fluid transportation. It is a known technology, and its specific structure can be found in Chinese Patent No. CN105757271B, published on July 6, 2018, which discloses a novel flow fine-tuning gate valve.

[0003] In the prior art, including the aforementioned patents, the flow control of the valve body is achieved through either manual control or motor drive control. However, regardless of whether it is manual control or motor drive, the biggest problem lies in the valve core. The valve core can be divided into a ball valve core or a plate valve core. When water flow directly impacts a ball valve core or a plate valve core, the potential energy is relatively large. Due to water erosion caused by prolonged immersion in liquid and the impact of water flow potential energy, the service life is short, and the valve core is prone to breakage, thus detaching from the drive component and being unable to perform the function of controlling the water flow. Utility Model Content

[0004] The purpose of this invention is to provide an automatic flow regulating gate device to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic flow regulating gate device includes a gate housing with a vertically parallel inlet and an outlet, and a ball cage mounting slot communicating with both. A first bell-shaped cylinder and a second bell-shaped cylinder are slidably disposed within the ball cage mounting slot, their ends facing each other, and the second bell-shaped cylinder is inserted into the port of the first bell-shaped cylinder.

[0007] The side wall of the second bell-shaped cylinder maintains a predetermined distance from the inner wall of the ball cage mounting slot, and multiple rounded rectangular water outlets are provided on it in a circumferential array.

[0008] The first bell-shaped cylinder has multiple rounded rectangular water inlets arranged in a circular array on one end face facing the bottom of the ball cage mounting slot.

[0009] It also includes an operating lever, which is threadedly assembled with the second bell-shaped cylinder and the first bell-shaped cylinder, and the two maintain relative movement.

[0010] Preferably, the sliding stroke of the first bell-shaped cylinder has a high position and a low position, and when it is in the low position, the bottom of the first bell-shaped cylinder maintains a predetermined distance from the bottom of the ball cage mounting slot to form a liquid receiving chamber communicating with the liquid inlet.

[0011] Preferably, the rounded rectangular water outlet is fixedly connected to the liquid outlet.

[0012] Preferably, a cover is fixedly installed at the end of the ball cage mounting slot by bolts, and the operating lever is rotatably disposed at the bottom of the cover and the ball cage mounting slot.

[0013] Preferably, a direct drive motor rotary table, which is pressed and secured by the cover, is inserted into the mounting slot of the ball cage, and the operating lever is inserted and secured to the output port at the axis of the direct drive motor rotary table.

[0014] Preferably, the outer wall of the direct drive motor rotary table is provided with a groove, and a first sealing strip is inserted into the groove, the first sealing strip abutting against the inner wall of the ball cage mounting slot.

[0015] Preferably, a flow rate sensor is installed inside the liquid outlet.

[0016] Preferably, the outer wall of the second bell-shaped cylinder has a groove, and a second sealing strip is fixedly installed in the groove, the second sealing strip being in contact with the inner wall of the first bell-shaped cylinder.

[0017] Preferably, both the first bell-shaped cylinder and the second bell-shaped cylinder are high-strength polyethylene composite plastic parts.

[0018] In the above technical solution, the automatic flow regulating gate device provided by this utility model has the following beneficial effects: the valve core adopts a design of a first bell-shaped cylinder and a second bell-shaped cylinder, and the bell-shaped structure design has higher structural strength and stronger resistance to the impact of water flow potential energy. The airflow and water flow enter between the first bell-shaped cylinder and the second bell-shaped cylinder through the rounded rectangular inlet at the bottom of the first bell-shaped cylinder, and then exit through the rounded rectangular outlet on the side wall of the second bell-shaped cylinder. By redesigning the flow channel, the combination allows the valve core to control the outflow of liquid more precisely than the traditional valve core design.

[0019] Furthermore, in this design, a flow velocity sensor detects the outflow velocity of the water, thereby controlling the direct-drive motor to rotate the operating lever, which in turn moves the first and second bell-shaped cylinders to control the flow rate, thus achieving automatic adjustment.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-3 This utility model provides a technical solution: an automatic flow regulating gate device, comprising: a gate housing 1, which includes a vertically parallel inlet 11 and an outlet 12, and a ball cage mounting slot 13 communicating with the two. A first bell-shaped cylinder 2 and a second bell-shaped cylinder 3 are slidably disposed in the ball cage mounting slot 13, with their ports facing each other, and the second bell-shaped cylinder 3 inserted into the port of the first bell-shaped cylinder 2, wherein:

[0028] The side wall of the second bell-shaped cylinder 3 maintains a predetermined distance from the inner wall of the ball cage mounting slot 13, and multiple rounded rectangular water outlets 31 are provided on it in a circumferential array.

[0029] The first bell-shaped cylinder 2 has multiple rounded rectangular water inlets 21 arranged in a circular array on one end face of the bottom end of the ball cage mounting slot 13.

[0030] It also includes an operating lever 4, which is threadedly assembled with the second bell-shaped cylinder 3 and the first bell-shaped cylinder 2, and the two maintain relative movement.

[0031] Specifically, both the first bell-shaped cylinder 2 and the second bell-shaped cylinder 3 are high-strength polyethylene composite plastic parts. The outer wall of the second bell-shaped cylinder 3 has a groove, and a second sealing strip 52 is fixedly installed within the groove, with the second sealing strip 52 abutting against the inner wall of the first bell-shaped cylinder 2. The rounded rectangular water outlet 31 is fixedly connected to the liquid outlet 12.

[0032] In the aforementioned technology, the valve core employs a design of a first bell-shaped cylinder 2 and a second bell-shaped cylinder 3. The bell-shaped structure design offers higher structural strength and greater resistance to the impact of water flow potential energy. The airflow / water flow enters between the first bell-shaped cylinder 2 and the second bell-shaped cylinder 3 through the rounded rectangular inlet 21 at the bottom of the first bell-shaped cylinder 2, and then exits through the rounded rectangular outlet 31 on the side wall of the second bell-shaped cylinder 3. This redesigned flow channel, combined with other features, allows the valve core to control the outflowing liquid more precisely compared to traditional valve core designs.

[0033] As a further embodiment of this utility model, the sliding stroke of the first bell-shaped cylinder 2 has a high position and a low position. When it is in the low position, the bottom of the first bell-shaped cylinder 2 maintains a predetermined distance from the bottom of the ball cage mounting slot 13 to form a liquid receiving chamber 7 communicating with the liquid inlet 11. When the first bell-shaped cylinder 2 is in the high position, the second bell-shaped cylinder 3 is completely embedded in the first bell-shaped cylinder 2, thereby blocking and sealing the rounded rectangular water inlet 21 on the side wall of the first bell-shaped cylinder 2. At this time, liquid enters from the liquid inlet 11 and cannot be discharged from the second bell-shaped cylinder 3 and the first bell-shaped cylinder 2, which are in a closed state, thereby achieving the purpose of cutting off the water flow.

[0034] As a further embodiment of this utility model, a cover 14 fixedly installed at the end of the ball cage mounting slot 13 by bolts is provided, and the operating lever 4 is rotatably disposed at the bottom of the cover 14 and the ball cage mounting slot 13. Furthermore, a direct drive motor rotary table 5 pressed and secured by the cover 14 is inserted into the ball cage mounting slot 13, and the operating lever 4 is inserted into the output port at the axis of the direct drive motor rotary table 5.

[0035] Secondly, the outer wall of the direct drive motor rotary table 5 is provided with a groove, and a first sealing strip 51 is inserted into the groove. The first sealing strip 51 abuts against the inner wall of the ball cage mounting slot 13.

[0036] Furthermore, a flow rate sensor 121 is installed inside the liquid outlet 12.

[0037] Furthermore, in the scheme, the flow rate sensor 121 detects the outflow speed of the water, thereby controlling the direct drive motor rotary table 5 to drive the operating lever 4 to rotate, thereby causing the first bell-shaped cylinder 2 and the second bell-shaped cylinder 3 to move for flow control, thus achieving the purpose of automatic adjustment.

[0038] It should be noted that the handle 6 is mounted on the operating lever 4. When a person rotates the handle 6, the operating lever 4 can be rotated forward or backward.

[0039] It should be noted that the aforementioned electronic components and electronic control programs are all common technical knowledge known to those skilled in the art, and therefore will not be described in detail.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
