DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0021] Traditionally, when testing water flow, the flowmeters used by most staff cannot adjust the water flow, which makes it impossible to set the water flow manually. The flowmeter can only detect a single water flow result and cannot meet the diverse water flow testing scenarios.

[0022] In view of this, the utility model provides a water flow automatic detection meter, which solves the problem that traditional flow meters cannot adjust water flow through an adjusting device. When the flow meter is detecting the water flow, workers can use the adjusting device to control the size of the water flow, thereby detecting the discharge volume of the adjusting device at different heights. Workers can adjust the adjusting device according to the detection results, thereby realizing the control and detection of the water flow.

[0023] Embodiment 1: By Figure 1 , 2, 3 and 4 show that a water flow automatic control detection meter includes a flow meter 1, a connecting valve 2 is installed on the outer wall of the flow meter 1, and the water flow automatic control detection meter also includes: a filtering device 3, which is arranged on one side of the inside of the connecting valve 2; an adjusting device 4, which is installed on the inside of the connecting valve 2; an anti-backflow device 5, which is arranged on the side of the inside of the connecting valve 2 away from the filtering device 3; the flow meter 1 and the connecting valve 2 can be fixed or separated by bolts, and a sealing gasket is arranged at the connection between the flow meter 1 and the connecting valve 2, which can prevent water from leaking from the interface, and the anti-backflow device 5 can prevent the water in the water pipe from flowing back, avoiding water pollution caused by water backflow, thereby affecting the normal use of users, wherein the filtering device 3 can filter impurities in the water, the adjusting device 4 can control the flow of water, and the anti-backflow device 5 can prevent the water from flowing back;

[0024] In the specific implementation process, it is worth pointing out that the flow meter 1 and the connecting valve 2 can be fixed or separated by bolts, and a sealing gasket is provided at the connection between the flow meter 1 and the connecting valve 2, which can prevent water from leaking from the interface, and the backflow prevention device 5 can prevent the water in the water pipe from flowing back, avoiding water pollution caused by water backflow, thereby affecting the normal use of users;

[0025] Specifically, when using the water flow automatic control detection meter, when the staff wants to detect the water flow, first install the flow meter 1 and the connecting valve 2 together, and then connect the two ends of the connecting valve 2 to the water pipe. Then the worker can pre-adjust the water flow through the adjusting device 4, and then the worker opens the valve, and the water flows through the water pipe into the connecting valve 2. First, the water flows through the filter device 3, and the filter device 3 filters the impurities in the water. Then the water flows through the adjusting device 4, and the adjusting device 4 limits the flow. The restricted water flow passes through the flow meter 1. At this time, the flow meter 1 will feed back the water flow to the display. The worker can adjust the adjusting device 4 according to the current water flow value to complete the automatic control detection of the water flow.

[0026] Embodiment 2: By Figure 1 , 2As can be seen from 3, the filter device 3 includes: a limit block 301, two of which are provided and are both installed on one side of the interior of the connecting valve 2; a filter plate 302, the number of which is not limited and can be satisfied as long as the use requirements are met, and is provided on the inner walls of the two limit blocks 301; an impeller 303, which is rotatably connected to the inner wall of the filter plate 302 through a sealed bearing; the limit block 301 plays a fixing role on the filter plate 302, and the filter plate 302 is processed with a plurality of holes, wherein the diameter of the hole on the side close to the impeller 303 is smaller than the diameter of the hole on the side away from the impeller 303, so that it is convenient to filter the water flow and impurities, and the impeller 303 can rotate along the inner wall of the filter plate 302 through the sealed bearing under the action of the fluid; wherein, when the water flow flows, the impeller 303 can be driven to rotate, and the filter plate 302 can intercept impurities in the water;

[0027] In the specific implementation process, it is worth pointing out that the limit block 301 plays a fixing role on the filter plate 302. The filter plate 302 is processed with a plurality of holes, wherein the diameter of the hole on the side close to the impeller 303 is smaller than the diameter of the hole on the side away from the impeller 303, so that the water flow and impurities can be easily filtered. Under the action of the fluid, the impeller 303 can rotate along the inner wall of the filter plate 302 through the sealed bearing;

[0028] Specifically, on the basis of the above-mentioned embodiment 1, when the water flows into the interior of the connecting valve 2, it will first pass through the impeller 303 and the filter plate 302. The filter plate 302 allows the water to pass normally, but will intercept impurities in the water to prevent the impurities from entering the interior of the regulating device 4 with the water flow and affecting the normal use of the regulating device 4. In addition, because the impeller 303 is rotatably connected to the inner wall of the filter plate 302 through a sealed bearing, when the water flows through the impeller 303, the impeller 303 is forced to rotate under the action of the fluid, and the rotation speed is proportional to the average flow velocity. The rotating impeller 303 can clean up the impurities embedded in the holes of the filter plate 302.

[0029] Embodiment 3: By Figure 1 and 2 It can be seen that the regulating device 4 includes: a threaded rod 401, which is rotatably connected to the inner wall of the connecting valve 2 through a sealed bearing; a slider 402, which is threadedly connected to the outer wall of the threaded rod 401; a vertical plate 403, which is installed inside the connecting valve 2 and fits with the outer wall of the slider 402; the vertical plate 403 is processed with two openings. Because the slider 402 fits with the vertical plate 403, when the slider 402 is close to the bottom of the vertical plate 403, the slider 402 will block the opening processed by the vertical plate 403. At this time, the water flow cannot pass through the vertical plate 403. When it is necessary to adjust the water flow, the slider 402 is driven to move toward the top of the vertical plate 403 by rotating the threaded rod 401. At this time, the opening processed by the vertical plate 403 is no longer affected by the blocking of the slider 402, and the vertical plate 403 can pass through the processed opening; wherein, the threaded rod 401 can drive the slider 402 to move along the inner wall of the vertical plate 403;

[0030] In the specific implementation process, it is worth pointing out that the vertical plate 403 is processed with two openings. Since the slider 402 fits the vertical plate 403, when the slider 402 is close to the bottom of the vertical plate 403, the slider 402 will block the opening processed by the vertical plate 403. At this time, the water flow cannot pass through the vertical plate 403. When the water flow needs to be adjusted, the slider 402 is driven to move toward the top of the vertical plate 403 by rotating the threaded rod 401. At this time, the opening processed by the vertical plate 403 is no longer affected by the blocking of the slider 402, and the water can pass through the vertical plate 403 from the processed opening.

[0031] Specifically, on the basis of the above-mentioned embodiment 1, when the staff adjusts the water flow, they first rotate the threaded rod 401. The threaded rod 401 is forced to rotate along the inner wall of the connecting valve 2 through the sealed bearing. Because the slider 402 is threadedly connected to the threaded rod 401, when the threaded rod 401 rotates, the slider 402 is forced to start sliding along the outer wall of the threaded rod 401. Because the vertical plate 403 is processed with two openings, when the slider 402 moves upward and leaves the bottom opening, the water flow can flow out normally from the opening processed by the vertical plate 403, but the water flow at this time is small. If the water flow needs to be increased, continue to rotate the threaded rod 401 until the threaded rod 401 drives the slider 402 to move to the top of the vertical plate 403. At this time, the two openings processed by the vertical plate 403 are no longer blocked by the slider 402, and the water flow can flow out through the two openings, thereby increasing the water flow.

[0032] Embodiment 4: By Figure 1 , 2 As can be seen from Figure 4, the backflow prevention device 5 includes: a fixed plate 501, which is installed inside the connecting valve 2; a baffle 502, which is plugged into the inner wall of the fixed plate 501; two limit plates 503 are provided, both of which are installed on one side of the inside of the connecting valve 2 and are in contact with the inner wall of the baffle 502; a spring 504, which is sleeved on the outer wall of the baffle 502 and is tightly pressed against the outer wall of the fixed plate 501; openings are respectively processed at both ends of the fixed plate 501, and water can flow out from the inner wall of the fixed plate 501 through the openings. When the water flow pushes the baffle 502 to move along the inner wall of the fixed plate 501, the spring 504 will be compressed by the pressure of the fixed plate 501 and the baffle 502. When the baffle 502 is no longer subjected to the thrust of the water flow, the spring 504 will extend and drive the baffle 502 to return to its initial position, wherein the water flow can drive the baffle 502 to move along the outer wall of the limit plate 503 through the fixed plate 501;

[0033] In the specific implementation process, it is worth pointing out that both ends of the fixed plate 501 are respectively processed with openings, and the water flow can flow out from the inner wall of the fixed plate 501 through the openings. When the water flow pushes the baffle 502 to move along the inner wall of the fixed plate 501, the spring 504 will be compressed by the pressure of the fixed plate 501 and the baffle 502. When the baffle 502 is no longer pushed by the water flow, the spring 504 will extend and drive the baffle 502 to return to the initial position.

[0034] Furthermore, grooves 6 are processed at both ends of the connecting valve 2;

[0035] Specifically, on the basis of the above-mentioned embodiment 1, when the water flows normally, the water flow will push the baffle 502 to move along the inner wall of the fixed plate 501, and at the same time, the front end of the baffle 502 will move along the outer wall of the limit plate 503 in the direction away from the limit plate 503 until the baffle 502 is separated from the limit plate 503. At this time, the water flow can pass through the opening generated by the separation of the baffle 502 and the limit plate 503. When backflow occurs, the water flow will push the baffle 502 to move in the direction close to the limit plate 503 until the baffle 502 is fitted with the limit plate 503. At this time, the water flow is blocked by the baffle 502 and cannot pass through, thereby completing the interception operation of the backflow. Before connecting the two ends of the connecting valve 2 to the water pipe, the sealing gasket can be placed in the groove 6, and the sealing gasket can prevent water from leaking from the interface.
