Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Examples, such as Figure 1-4 As shown, the utility model provides an integrated solenoid valve with a flow meter, comprising: a pipe body 1, and also comprising: a water outlet 105, which is arranged at one end of the pipe body 1, and the inside of the water outlet 105 is fixedly connected to a guide cylinder 3, and the inner wall of the guide cylinder 3 is fixedly connected to a cross-shaped plate 301, and a rotating rod 302 is rotatably connected to the center of the cross-shaped plate 301, and the outer surface of the rotating rod 302 is fixedly connected to a plurality of magnet pieces 303 in a circular array, and one end of the rotating rod 302 is fixedly connected to an impeller 304, and the outer surface of the pipe body 1 near the water outlet 105 is fixedly connected to a Hall sensor assembly 102.

[0026] Further, such as Figure 1-4 As shown, a valve head shell 2 is provided on the outer surface of the pipe body 1, and a mounting seat 201 is fixedly connected to one side of the valve head shell 2. The mounting seat 201 is fixedly connected to the pipe body 1 by screws. A sealing groove 104 is provided inside the pipe body 1, and a water inlet 103 is provided at one end of the pipe body 1 away from the water outlet 105. The water inlet 103, the sealing groove 104 and the water outlet 105 are connected. Through the above arrangement, the fluid medium can pass through the water inlet 103, the sealing groove 104 and the water outlet 105 in sequence.

[0027] Further, such as Figure 1-4 As shown, an electromagnetic coil 203 is fixedly connected to the inside of the valve head housing 2, and a wiring terminal 202 connected to the electromagnetic coil 203 is provided on one side of the valve head housing 2. By connecting the wiring terminal 202 to an external power supply and passing current in opposite directions to the electromagnetic coil 203 through the controller, an electromagnetic field in opposite directions can be generated.

[0028] Further, such as Figure 1-4 As shown, the inner wall of the valve head shell 2 is fixedly connected to a static iron core 204, the interior of the valve head shell 2 is slidingly connected to a moving iron core 205, and an iron core spring 206 is provided inside the valve head shell 2. The iron core spring 206 is fixedly connected to the static iron core 204 and the moving iron core 205 respectively. Under the elastic force of the iron core spring 206, the moving iron core 205 will be moved away from the static iron core 204.

[0029] Further, such as Figure 1-4As shown, the inner wall of the valve head housing 2 is movably connected with a plug 207, and the plug 207 is engaged with the moving iron core 205. The internal sealing sliding connection of the valve head housing 2 is a sealing ring 211, and the sealing ring 211 is fixedly connected to the plug 207. Through the setting of the sealing ring 211, a certain sealing effect is played.

[0030] Further, such as Figure 1-4 As shown, a mounting groove is provided on the outer surface of the pipeline body 1 near the valve head shell 2, and a bracket 208 is fixedly connected to the inner wall of the valve head shell 2 away from the static iron core 204. A sealing diaphragm 210 is fixedly connected to one side of the plug 207. The sealing diaphragm 210 is slidably connected to the bracket 208. The sealing diaphragm 210 is slidably connected to the inside of the sealing groove 104. A pressure relief hole is provided on the inner wall of the valve head shell 2 near the plug 207. By blocking the pressure relief hole with the plug 207, the pressure on the upper end of the sealing diaphragm 210 can be supplemented by the inlet pressure and gradually tend to be balanced with the inlet. The sealing diaphragm 210 moves downward due to the water pressure.

[0031] Further, such as Figure 1-4 As shown, a diaphragm spring 209 is provided inside the bracket 208, and the diaphragm spring 209 is fixedly connected to the valve head housing 2 and the sealing diaphragm 210 respectively.

[0032] Further, such as Figure 1-4 As shown, a flexible joint 101 is provided on the outer surface of the pipe body 1 near the water inlet 103. The flexible joint 101 facilitates connection with an external pipe.

[0033] Working principle: When in use, the fluid medium enters the interior of the pipe body 1 from the water inlet 103, passes through the sealing groove 104, and finally flows out through the water outlet 105. When the fluid medium passes through the interior of the guide tube 3, the impeller 304 will rotate under the force of the flow of the fluid medium, and synchronously drive the rotating rod 302 and the magnet piece 303 to rotate. The polarity of the outward side of each adjacent magnet piece 303 is opposite, so that each time the magnet piece 303 passes the position of the terminal 202, the Hall sensor chip in the terminal 202 can sense the passage of the magnet piece 303 of different polarity and output a pulse signal. The pulse signal is received by the pulse receiving device, and the number of pulses of the Hall sensor chip is read. The flow rate of the fluid medium in the pipeline is calculated through the calibrated conversion formula, so that the flow meter and the solenoid valve are connected. The structure is such that when the flow in the pipeline is controlled by the solenoid valve, the flow of the fluid medium in the pipeline can also be detected. When it is necessary to control and close the water flow in one of the pipelines, the terminal 202 is connected to the external power supply, and the electromagnetic coil 203 is reversely energized through the controller, so that the moving iron core 205 is separated from the static iron core 204 under the elastic force of the electromagnetic force and the iron core spring 206, and the plug 207 is extended to close the pressure relief hole. The pressure on the upper end of the sealing diaphragm 210 is supplemented by the inlet pressure and gradually tends to be balanced with the inlet. The sealing diaphragm 210 is pressed against the sealing surface of the sealing groove 104 due to the water pressure and the elastic force of the diaphragm spring 209, thereby closing the pipeline body 1, so that the water flow inside the pipeline body 1 can be controlled. The structure is simple and the manufacturing cost is low. Otherwise, it can be opened.
