Description

Technical Field

[0001] This utility model relates to the field of control valve technology, specifically to an intelligent control valve. Background Technology

[0002] Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in highly complex automated control systems, with a wide variety of types and specifications. One such valve is listed in the announcement number CN 213361150. U, an intelligent control valve, includes a valve body, a first channel, and a second channel. A support block is located at the top center of the valve body and is fixedly connected to the valve body. An electric telescopic rod is located at the top of the support block and is fixedly connected to the support block. A first pipe is located at the bottom of the support block, passing through the support block and the valve body. A control pipe is located in the middle of the valve body and is fixedly connected to the valve body. Both ends of the control pipe are connected to the first channel and the second channel, respectively. The advantages are: the electrical connection between the controller and the electric telescopic rod enables automatic control of the valve plate; the flow monitor enables real-time monitoring of the flow in the pipe and transmits the information to the control display via a second data line; the control display enables real-time display and operation of the flow; and the first and second data transmission lines enable the transmission of control and detection information, achieving automatic control.

[0003] The above solution has the following shortcomings in actual operation: When the valve plate is used to cut off the water flow in the valve body, since the water flow is horizontal while the valve plate moves vertically, the valve plate will be subjected to forces in the horizontal direction during the process of cutting off the water flow. At the same time, the surface of the valve plate will also be subjected to uneven water pressure during the process of cutting off part of the water flow. As a result, the valve plate is very easy to bend, which makes it impossible to move up and down smoothly to close the valve body. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an intelligent control valve that has the advantage of positioning plastics and avoids the problem of irregular deformation caused by plastic stretching.

[0005] To achieve the purpose of positioning plastic, this utility model provides the following technical solution:

[0006] A smart control valve includes a valve body, wherein a limit ring is fixedly connected to the inner wall of the valve body, and further includes:

[0007] Two sets of connecting pipes are fixedly connected to the side wall of the valve body, and the connecting pipes are distributed on the upper and lower sides of the limiting ring. A first telescopic cylinder is fixedly connected to the bottom of the valve body. A sliding plate is fixedly connected to the output end of the first telescopic cylinder, and the sliding plate is in contact with the inner wall of the valve body. A conical block is fixedly connected to the top of the sliding plate, and the conical block can close the limiting ring.

[0008] According to some embodiments, a sleeve is fixedly connected to the top of the valve body, a second telescopic cylinder is fixedly connected to the top of the sleeve, a locking block is fixedly connected to the output end of the second telescopic cylinder, a pressure sensor is fixedly connected to the bottom end of the locking block, and a pressure relief pipe is fixedly connected to the side wall of the sleeve.

[0009] According to some embodiments, the bottom of the limiting ring is provided with a slot, the top of the sliding plate is fixedly connected with a sealing ring, and the sealing ring can extend into the inner cavity of the slot. The end of the connecting pipe is fixedly connected with a flange ring, and the side wall of the flange ring is provided with multiple sets of threaded holes. Beneficial effects

[0010] This utility model provides an intelligent control valve, which has the following beneficial effects:

[0011] (1) The intelligent control valve drives the first telescopic cylinder to move the sliding plate up and down. The conical block at the top of the sliding plate can close the limiting ring, thereby isolating the water flow and closing the valve body. Since the side wall of the conical block is set to be inclined, the water pressure on the conical block can be reduced. At the same time, during the process of the top of the conical block sliding into the limiting ring, the water flow that can pass through the limiting ring will be slowly reduced, thereby controlling the water flow of the valve body.

[0012] (2) The intelligent control valve has a locking block located below the pressure relief pipe to isolate the pressure relief pipe. The pressure sensor can measure the water pressure in the valve body cavity. When the water pressure is too high, the second telescopic cylinder can drive the locking block to move up to the top of the pressure relief pipe. At this time, the water in the valve body cavity can flow out in a small amount through the pressure relief pipe, thereby reducing the water pressure on the valve body and the conical block.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-4 A smart control valve includes a valve body 1, with a limit ring 101 fixedly connected to the inner wall of the valve body 1, and further includes:

[0020] Two sets of connecting pipes 2 are fixedly connected to the side wall of the valve body 1, and the connecting pipes 2 are distributed on the upper and lower sides of the limiting ring 101. A first telescopic cylinder 201 is fixedly connected to the bottom of the valve body 1. A sliding plate 202 is fixedly connected to the output end of the first telescopic cylinder 201, and the sliding plate 202 is in contact with the inner wall of the valve body 1. A conical block 203 is fixedly connected to the top of the sliding plate 202, and the conical block 203 can close the limiting ring 101.

[0021] It should be noted that: driving the first telescopic cylinder 201 causes the sliding plate 202 to slide upward. The conical block 203 at the top of the sliding plate 202 can close the limiting ring 101, thereby isolating the water flow and completing the closure of the valve body 1. At the same time, since the side wall of the conical block 203 is set to be inclined, the water flow that can pass through the limiting ring 101 will slowly decrease during the process of the top of the conical block 203 sliding upward into the limiting ring 101, thereby controlling the water flow of the valve body 1. The connecting pipe 2 is used to connect to the external water pipe.

[0022] Reference Figures 1-4 A sleeve 3 is fixedly connected to the top of the valve body 1, a second telescopic cylinder 301 is fixedly connected to the top of the sleeve 3, and a locking block 302 is fixedly connected to the output end of the second telescopic cylinder 301.

[0023] A pressure sensor 303 is fixedly connected to the bottom of the locking block 302, and a pressure relief pipe 304 is fixedly connected to the side wall of the sleeve 3.

[0024] It should be noted that the locking block 302 is located below the pressure relief pipe 304 to isolate the pressure relief pipe 304. The pressure sensor 303 at the bottom of the locking block 302 can measure the water pressure inside the valve body 1. When the water pressure is too high, it can drive the second telescopic cylinder 301. The second telescopic cylinder 301 drives the locking block 302 to move upward above the pressure relief pipe 304. At this time, the water in the valve body 1 can flow out in a small amount through the pressure relief pipe 304, thereby reducing the water pressure on the valve body 1.

[0025] Reference Figures 1-4 The bottom of the limiting ring 101 is provided with a slot 4, and the top of the sliding plate 202 is fixedly connected with a sealing ring 401, which can extend into the inner cavity of the slot 4.

[0026] A flange ring 402 is fixedly connected to the end of the connecting pipe 2, and multiple sets of threaded holes are opened on the side wall of the flange ring 402.

[0027] It should be noted that when the conical block 203 closes the limiting ring 101, the sealing ring 401 at the top of the sliding plate 202 can slide into the inner cavity of the slot 4, which can seal the limiting ring 101 and thus prevent the limiting ring 101 from leaking water. The flange ring 402 provided on the side wall of the connecting pipe 2 can be used to connect the external water pipe.

[0028] Operation method: Drive the first telescopic cylinder 201, so that the first telescopic cylinder 201 drives the sliding plate 202 to slide upward. The conical block 203 at the top of the sliding plate 202 can close the limiting ring 101. The sealing ring 401 at the top of the sliding plate 202 can slide into the inner cavity of the slot 4, which plays the role of sealing the limiting ring 101, thereby isolating the water flow and completing the closure of the valve body 1. At the same time, since the side wall of the conical block 203 is set to be inclined, the water flow that can pass through the limiting ring 101 will slowly decrease during the process of the top of the conical block 203 sliding upward into the limiting ring 101, thereby controlling the water flow of the valve body 1.

[0029] The locking block 302 is located below the pressure relief pipe 304 to isolate the pressure relief pipe 304. The pressure sensor 303 at the bottom of the locking block 302 can measure the water pressure inside the valve body 1. When the water pressure is too high, it can drive the second telescopic cylinder 301. The second telescopic cylinder 301 drives the locking block 302 to move upward above the pressure relief pipe 304. At this time, the water in the valve body 1 can flow out in a small amount through the pressure relief pipe 304, thereby reducing the water pressure on the valve body 1. The flange ring 402 provided on the side wall of the connecting pipe 2 can be used to connect the external water pipe.
