According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc., and some valves are equipped with flow meters to detect water flow.

[0003] In the prior art, for example, Chinese patent application CN115325254A discloses a water-saving valve for accurately detecting water flow, which includes a controller, a pneumatic mechanism, a valve stem, a valve core and a valve body.

[0004] However, in the prior art, when the valve is used for a long time, the connection between the valve and the pipeline may leak due to the aging of the sealing gasket, and the flow meter on the valve can only detect the flow rate of water in the valve, but cannot detect leakage. It can only be discovered during maintenance and when the leakage is more obvious, which leads to waste of water resources during use. If the leakage is not handled in time, accidents may easily occur, such as damage to electrical equipment and bursting of the connection, which is very dangerous.

DETAILED DESCRIPTION

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

[0020] Embodiment 1 Reference Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 8As shown: a valve with flow detection function, including an electromagnetic valve 1, a control box 2 is arranged on one side of the electromagnetic valve 1, two corners below one side of the control box 2 are arranged with connecting rods 4, one side of the two connecting rods 4 is arranged with fixed sleeves 6, a rubber head 8 is slidably connected inside the fixed sleeve 6, one end of the rubber head 8 is fixedly connected with a connecting slide rod 9, one end of the connecting slide rod 9 passes through the fixed sleeve 6 and is fixedly connected with an end-mounted block 18, one side of the end-mounted block 18 is fixedly connected with a convex rod 10, the convex rod 10 is slidably connected to the first slide groove 5, a second spring 20 is fixedly connected between one end of the rubber head 8 and the fixed sleeve 6, the control box 2 is provided with a control module 22 and an angle sensor 26, the angle sensor 26 is connected to one end of the connecting rod 4, the angle sensor 26 is used to detect the change of the inclination angle of the connecting rod 4, and a pedestal installed in cooperation with the fixed sleeve 6 needs to be installed on the pipeline connected to the electromagnetic valve 1, and the pedestal needs to be as far away from the electromagnetic valve 1 as possible to increase the detection accuracy. According to different usage scenarios, when the water flow is small and sometimes the water flow in the pipeline is not enough to fill the entire pipeline, the second spring 20 with smaller elasticity needs to be selected for installation and use. When the water flow is large, the second spring 20 with larger elasticity needs to be selected for use.

[0021] In this embodiment, through the setting of the angle sensor 26 and the connecting rod 4, when in use, the faster the flow rate of the water flow, the greater the impact force of the water flow on the rubber head 8, so that the rubber head 8 slides into the fixed sleeve 6 for a greater distance, so that the connecting slide rod 9 moves, driving the connecting rod 4 to rotate, and the angle change is detected by the angle sensor 26, and then the pressure value is converted to obtain the water flow rate. At the same time, this design can detect the water flow rate on both sides of the electromagnetic valve 1. When one side of the electromagnetic valve 1 leaks, the water flow rate on one side will change. If both sides of the electromagnetic valve 1 leak, the pressure value gradually decreases with the direction of the water flow, so as to judge whether the connection of the electromagnetic valve 1 is leaking, and cooperate with the control module 22 to send information to the main control console to remind the staff to repair in time to reduce losses.

[0022] Embodiment 2 Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, the lower end of the electromagnetic valve 1 is connected to a flow meter 3, the other end of the fixed sleeve 6 is fixedly connected to a reinforcement sleeve 7, one end of the fixed sleeve 6 is fixedly connected to a reinforcement sleeve 19, the interior of the reinforcement sleeve 19 is slidably connected to the connecting slide rod 9, and an annular groove 21 is provided on the outer surface of the convex rod 10. The flow meter 3 is used to detect the water flow in the electromagnetic valve 1, and the reinforcement sleeve 7 is used to be inserted into the pedestal of the connecting pipe to increase the connection stability. The reinforcement sleeve 19 is used to increase the force-bearing area of ​​the connecting slide rod 9 to make the sliding of the connecting slide rod 9 smoother. Through the setting of the annular groove 21, the surface of the convex rod 10 can be smeared with lubricating oil during use, and the annular groove 21 can store an additional part, reduce the loss of lubricating oil, increase the service life, and make the sliding of the convex rod 10 in the No. 1 slide groove 5 smoother, thereby increasing the detection accuracy.

[0023] Embodiment 3 according to Figure 8 As shown, the control module 22 includes a signal receiving module 23, a processing module 24 and a signal transmission module 25. The signal receiving module 23 is used to receive information from the angle sensor 26 and the flow meter 3. The processing module 24 is used to identify and judge the collected information. The signal transmission module 25 is used to transmit the information to the main control console. The electromagnetic valve 1 is connected to the main control console by signal. The electromagnetic valve 1 is electrically connected to the control module 22. When the flow meter 3 is in use, the flow information is transmitted to the control module 22 and the main control console. The electromagnetic valve 1 transmits the switch information to the main control console and the control box 2. When the electromagnetic valve 1 is closed, the processing module 24 no longer receives the information transmitted by the angle sensor 26, and records the flow information and angle information before the electromagnetic valve 1 is closed. When the electromagnetic valve 1 is opened, the processing module 24 compares the angle information transmitted by the two angle sensors 26 with the information before the electromagnetic valve 1 is closed, and detects whether the angle of the connecting rod 4 on one side has changed to determine whether there is a leak.

[0024] Embodiment 4 according to Figure 3 - Figure 5 As shown, the outer surface of the solenoid valve 1 is fixedly connected with a mounting frame 11, and mounting slots 12 are provided on both sides of the mounting frame 11. A No. 2 slide groove 15 is provided through the upper middle part of one side of the control box 2, and both sides of the No. 2 slide groove 15 are slidably connected with a snap-on slider 13, and a No. 1 spring 14 is fixedly connected between the two snap-on sliders 13. One side of the two snap-on sliders 13 is fixedly connected with an end plate 16, and one side of the end plate 16 is fixedly connected with a reinforcing rib 17.

[0025] In this embodiment, the through-type design of the second slide groove 15 can facilitate the disassembly of the card-connecting sliders 13 on both sides. The design of the end plate 16 can facilitate the adjustment of the position of the card-connecting slider 13 to facilitate the connection with the mounting card groove 12, thereby facilitating the installation and disassembly of the control box 2. The setting of the reinforcing rib 17 is used to increase the supporting strength of the end plate 16, and prevent the end plate 16 from being deformed when the end plate 16 is pulled. In addition, the design can selectively install the control box 2 and the fixed sleeve 6 according to actual conditions. When the control box 2 and the fixed sleeve 6 are needed, a pipe that can be installed in conjunction with the fixed sleeve 6 is selected for use. When the control box 2 is not needed, an ordinary pipe can be used, which needs to be replaced later. When the fixed sleeve 6 is used, there is no need to replace the solenoid valve 1, thereby reducing the replacement cost.

[0026] The use method and working principle of this device: During installation, first install the two sides of the electromagnetic valve 1 with the pipeline, then connect the convex rod 10 with the No. 1 slide groove 5, then insert the reinforcement sleeve 7 into the pedestal set on the pipeline, and then fix the fixed sleeve 6 with the pedestal. After the installation is completed, the outer ring surface of the convex rod 10 needs to be coated with lubricating oil, and the lubricating oil needs to enter the annular groove 21. After the installation is completed, the electromagnetic valve 1 is opened to allow the water to flow. The flowing water will impact the rubber head 8, causing the rubber head 8 to move, thereby causing the connecting slide rod 9 to slide a certain distance in the fixed sleeve 6, pushing the connecting rod 4 to rotate a certain angle. When there is no leakage on both sides of the electromagnetic valve 1, the two connecting rods 4 have the same inclination angle. When one side leaks, the water flow on one side will decrease, and it can be judged whether there is a leak. At this time, the signal transmission module 25 transmits information to the main control console to remind the maintenance personnel to perform maintenance. At this time, the main control console controls the electromagnetic valve 1 in the corresponding interval to be closed to reduce losses. When installing the control box 2, pull the end plates 16 on both sides to expand the two snap-fitting slides 13 until they can be inserted into the installation slots 12. Then align the snap-fitting slides 13 with the installation slots 12, loosen the end plates 16, and slide the snap-fitting slides 13 into the installation slots 12 to install the mounting frame 11 between the control box 2.
