[0014] 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 them. 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.
[0015] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention. Example
[0016] See attached Figure 1As shown, an intelligent steel-plastic conversion joint includes a joint body 1, a flange 2 is provided on the top of the joint body 1, a connecting end 3 is provided at the bottom end of the joint body 1, an electric air valve 4 is installed on the joint body 1, two air pressure detectors 5 are fixedly installed on the right side of the joint body 1, one air pressure detector 5 is located above the electric air valve 4, and the other air pressure detector 5 is located below the electric air valve 4, a PLC controller 6 is fixedly installed on the left side of the joint body 1, the power supply line of the electric air valve 4 is connected to the PLC controller 6, a buzzer 7 is electrically connected to the bottom of the PLC controller 6, and two indicator lights 8 are electrically connected to the front side of the PLC controller 6, one indicator light 8 is electrically connected to the upper air pressure detector 5, and the other indicator light 8 is electrically connected to the lower air pressure detector 5.
[0017] A power socket 9 and a battery compartment 10 are provided on the top of the PLC controller 6 .
[0018] A wireless module is provided inside the PLC controller 6 .
[0019] Working principle: In the utility model, the steel pipe is connected at the flange 2, and the connecting end 3 is used to sleeve the plastic pipe. The electric gas valve 4 is in a long-open state. The gas is transported from the steel pipe through the joint body 1 to the plastic pipe. The detection end of the upper air pressure detector 5 is inserted into the opening at the end of the steel pipe, and the detection end of the lower air pressure detector 5 is inserted into the opening at the end of the plastic pipe. When the air pressure data of the two air pressure detectors 5 are abnormal, it means that there is a leak at the end. At this time, the PLC controller 6 controls the buzzer 7 to emit a warning sound and transmits the leakage signal to the wireless module. The wireless module sends the data to the mobile terminal. After the terminal issues an instruction to close the electric gas valve 4, the signal is transmitted from the wireless module back to the PLC controller 6, and the PLC controller 6 controls the electric gas valve to close. At this time, if there is a leak at the connecting end 3 connected to the plastic pipe, the air pressure of the upper air pressure detector 5 will return to normal data, and the air pressure will no longer be too small. At this time, an indicator light 8 flashes. On the contrary, if there is a leak at the steel pipe connection, the upper air pressure detector 5 still maintains abnormal data, and the other indicator light 8 flashes.
[0020] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
