The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Referring to fig. 1-4, an internet of things electromagnetic valve comprises a valve body 4, a mounting cylinder 5 is detachably connected to the top end of the valve body 4, a cover plate 6 is arranged on the top end of the mounting cylinder 5, an electromagnetic mechanism is detachably connected to the top surface of the cover plate 6, a movable iron core 11 is slidably connected to the bottom center of the mounting cylinder 5, the top end of the movable iron core 11 is connected with the electromagnetic mechanism, a manual control mechanism is arranged on the upper portion of the movable iron core 11 and comprises a connecting rod 16, one end of the connecting rod 16 is fixedly connected with the upper portion of the movable iron core 11, the other end of the connecting rod passes through a square groove on the mounting cylinder 5 and is outside the square groove, an internet of things communication module 8 is further arranged on the top surface of the cover plate 6, a connector 2 is arranged on the internet of things communication module 8, and the connector 2 is an SMA connector.

In the embodiment of the utility model, when the electromagnetic valve mechanism fails or is powered off, the connecting rod 16 on the manual control mechanism can be used for manually controlling the up-and-down movement of the movable iron core 11, so as to complete the opening and closing of the electromagnetic valve. If the electromagnetic mechanism fails or fails, the electromagnetic mechanism and the manual control mechanism are not directly related, so that the electromagnetic mechanism can be independently disassembled to replace the electromagnetic mechanism or maintain the electromagnetic mechanism while the electromagnetic valve can be opened and closed, the whole electromagnetic valve is not required to be disassembled from a pipeline, and the effect of convenient maintenance is achieved. The installation cylinder 5 and the valve body 4 are detachably connected through screws, so that the whole installation cylinder 5 and parts on the installation cylinder 5 can be conveniently removed when the piston 15 is overhauled. Remote monitoring to the solenoid valve can be realized through the thing networking communication module 8 of setting up to in time discover the problem, through the SMA connector of setting up, can make its external antenna, so prevent to lead to signal transmission to receive the problem emergence that influences because of solenoid valve mounted position is more concealed.
