Under normal conditions, because the middle of the reticular wire 2 is provided with the broken joint 8, when the external wire 4 is connected, the broken joint 8 is disconnected, a loop is not formed, the alarm device 5 does not give an alarm, when the inner wall of the pipe fitting 1 is worn to the position of the broken joint 8, the broken joint 8 is filled with a medium, the two sections of the reticular wires 2 are communicated by the medium to form the loop, so that the external alarm device sends out an early warning signal, and a pipeline maintainer is reminded to replace the worn part.

Preferably, a power supply 7 and a switch 6 are connected to the external lead 4. The power source 7 is preferably a mobile power source such as a dry cell battery, a storage battery, or the like.

Preferably, a wire joint 3 is fixed at the end part of the reticular wire 2 far away from the broken seam 8, the wire joint is exposed out of the surface of the pipe fitting 1, and the wire joint 3 corresponds to the end of the external wire 4. It will be appreciated that this arrangement provides ease of service.

Preferably, the wire joint 3 is detachably connected with the external wire 4, so that the pipe fitting 1 can be inspected regularly.

Preferably, the pipe fitting 1 is an elbow pipe fitting, and the easily-worn part is a corner of the elbow pipe fitting.

Preferably, the pipe fitting 1 is a tee pipe fitting, and the easily-worn part is a corner of the tee pipe fitting. In general, when the pipe fitting 1 is worn, because the resistance at the corner of the pipe fitting 1 is the largest and the wear at the corner is the most serious, the pipe fitting wear warning device of the present invention can be arranged only at the position of the elbow pipe fitting or the tee pipe fitting, that is, the mesh wire 2 is embedded only at the position of the elbow pipe fitting or the tee pipe fitting.

Preferably, the alarm device 5 is a light emitting diode. The light emitting diode is a semiconductor component and is used as an indicator light, a display light emitting diode plate and the like; the utility model has the characteristics of energy saving, environmental protection, long service life, small volume and the like, and when weak current flows, the light emitting diode emits striking light to remind an operator of leakage of the pipe fitting 1.
