[0029] The technical solution of the present invention will be more clearly and completely explained below by describing the preferred embodiments of the present invention in combination with the accompanying drawings.

[0030] like Figure 1 and Figure 2 In the preferred embodiment shown, the integrated intelligent three-way electric valve 100 includes a valve body portion 1 and a control portion 2 . The control portion 2 is located above the valve body portion 1 and is used to control the operation of the three-way electric valve 100 .

[0031] The valve body 1 includes an inlet pipe 10, a first outlet pipe 11, a second outlet pipe 12 and a valve core 13. The inlet pipe 10 is vertical and its opening faces downward; the upper end of the inlet pipe 10 is connected to a cylindrical pipe 14, and the first outlet pipe 11 and the second outlet pipe 12 are respectively connected to the two sides of the cylindrical pipe 14 and are located on the same horizontal line, with their openings facing the left and right sides respectively. The valve core 13 is arranged in the cylindrical pipe 14, that is, between the first outlet pipe 11 and the second outlet pipe 12. Holes are opened at the bottom, left and right of the valve core 13, which are respectively used to lead to the inlet pipe 10, the first outlet pipe 11 and the second outlet pipe 12, so that water can enter the valve core 13 from the inlet pipe 10, and then flow out from the first outlet pipe 11 and the second outlet pipe 12. By rotating the valve core 13, the area of ​​the valve core hole communicating with the first water outlet pipe 11 and the second water outlet pipe 12 is changed, so that the flow of the three-way electric valve can be adjusted. This is the working principle of the traditional three-way valve and will not be repeated here.

[0032] like Figure 2 and Figure 3 As shown, the control part 2 includes a mounting seat shell 21, a cover shell 22, an actuator 23, and a main controller 24. The mounting seat shell 21 is directly connected to the valve body part 1, and a receiving space for receiving the actuator 23 and the main controller 24 is formed in the mounting seat shell 21. The cover shell 22 covers the mounting seat shell 21 and acts as an upper cover.

[0033] Further, the mounting seat shell 21 includes an upper shell 211 and a lower shell 212. The lower shell 212 includes a circular portion 212a and protrusions 212b located on both sides of the circular portion 212a. The circular portion 212a matches the cylindrical tube 14 located on the periphery of the valve core 13, and the two are connected. The protrusions 212b on both sides are respectively located above the first water outlet pipe 11 and the second water outlet pipe 12, and are adjacent to the upper surfaces of the first water outlet pipe 11 and the second water outlet pipe 12. The circular portion 212a is fixedly connected to the upper mounting surface 140 of the cylindrical tube 14 by bolts 3, thereby connecting the mounting seat shell 21 and the valve body part 1 together.

[0034] like Figure 3 As shown, the upper shell 211 of the mounting seat shell 21 is rectangular, and a receiving space 210 for receiving the actuator 23 and the main controller 24 is formed therein. Further, the receiving space 210 is divided into a first receiving area 210a, a second receiving area 210b, and a third receiving area 210c by a partition, wherein the first receiving area 210a and the second receiving area 210b extend along the length direction of the mounting seat shell 21 and are parallel to each other, and the third receiving area 210c extends along the width direction of the mounting seat shell 21 and is located at one end of the first receiving area 210a and the second receiving area 210b. The division of the receiving space 210 can more effectively utilize the internal space of the mounting seat shell 21.

[0035] Combination Figure 3 , Figure 4 and Figure 6 As shown, the actuator 23 is accommodated in the first accommodation area 210a, which includes a motor 231, a gear transmission mechanism 232, and an angle controller 233. The motor 231 drives the valve core 13 to rotate through the gear transmission mechanism 232. Specifically, the top of the valve core 13 is connected to the transmission shaft 130, and the transmission shaft 130 passes through the lower shell 212 and extends into the accommodation space, and is connected to the gear transmission mechanism 232, so that the valve core 13 is driven to rotate by the motor 231. The angle controller 233 is used to control the rotation angle of the valve core 13. Preferably, in this embodiment, the angle controller 233 is a micro-stroke switch. The battery 25 is accommodated in the second accommodation area 210b. The main controller 24 is accommodated in the third accommodation area 210c. According to the respective structures and shape characteristics of the actuator 23, the main controller 24 and the battery 25, the three are arranged in the accommodation area with corresponding shape characteristics in this embodiment, so that the space utilization of the mounting seat shell 21 is more reasonable, the internal structure is more compact, and it is conducive to reducing the overall size of the entire three-way electric valve.

[0036] like Figures 4 to 6 As shown, the three-way electric valve 100 also includes a flow sensor 4 and a pressure sensor 5. The flow sensor 4 is arranged in the first water outlet pipe 11, and is used to sense the flow of water. Specifically, the flow sensor 4 is fixedly mounted on the pipe wall of the first water outlet pipe 11, and its upper end is covered by the protrusion 212b located there. The pressure sensor 5 is arranged above the valve core 13, and is used to sense the pressure of water. Specifically, the pressure sensor 5 is fixedly mounted on the upper mounting surface 140 of the cylindrical tube 14, and its upper end is covered by the circular portion 212a. The flow sensor 4 and the pressure sensor 5 send the sensed flow signal and pressure signal to the main controller 24 respectively. The main controller 24 receives the signal and controls the actuator 23 to operate according to the preset parameters, drives the valve core 13 to rotate, thereby adjusting the flow, so that the flow and pressure of the water in the valve body are maintained within the preset parameter range.

[0037] In this embodiment, the three-way electric valve 100 is a one-inlet and two-outlet type, so the flow sensor 4 can also be arranged in the second water outlet pipe 12. The utility model integrates the flow sensor 4 and the pressure sensor 5 in the three-way electric valve, and compared with the existing three-way electric valve, the integration is greatly improved and the external dimensions are reduced, thereby forming an integrated intelligent three-way electric valve of the utility model.

[0038] A solar panel 220 is disposed on the top of the housing 22 , which converts solar energy into electrical energy and stores the electrical energy in the battery 25 , thereby utilizing solar energy to power the three-way electric valve 100 .

[0039] Combination Figure 6 and Figure 7 As shown, the three-way electric valve 100 also includes an antenna 6, which is arranged on one side of the cover 22, and further, is arranged on a side close to the main controller 24, so as to be electrically connected to the main controller 24, and is used to send the operating parameters of the three-way electric valve to the mobile phone or the control platform, so that the user and the control platform can understand the status of the three-way electric valve in real time and make adjustments. At the same time, the user and the control platform can also set the parameters of the three-way electric valve through the human-machine interface and the remote monitoring system respectively, thereby realizing remote monitoring and intelligent control of the three-way electric valve. The three-way electric valve can transmit data with the mobile phone and the control platform through the base station via 4G / GPRS / NB-IoT.

[0040] The above specific implementations are only descriptions of the preferred implementations of the utility model, and do not limit the protection scope of the utility model. Under the premise of not departing from the design concept and spirit of the utility model, various deformations, substitutions and improvements made by ordinary technicians in this field to the technical solution of the utility model based on the text description and drawings provided by the utility model should all fall within the protection scope of the utility model. The protection scope of the utility model is determined by the claims.
