[0026] Working principle: after the water pipe 3 is threadedly connected with the joint 2, the surface thereof is sealed by winding with the insulating tape 8, then the elastic bag 5 filled with the superabsorbent resin 15 is sleeved on the surface of the joint 2 and the water pipe 3 through the elastic ring 4, and the elastic ring 4 is made of elastic rubber material and can be tightly clamped with the surface thereof, at this time, the first mesh cover 7 and the second mesh cover 14 are sleeved on the surface of the electromagnetic valve 1 and are clamped and positioned with the water pipes 3 on both sides, which can play a protective role on the electromagnetic valve 1, at this time, the two elastic bags 5 are respectively located at the inner walls of the corresponding ring sleeves 10, when the joint 2 on the electromagnetic valve 1 leaks at the connection position with the water pipe 3, water leaks from the gap at the connection position into the elastic bag 5, at this time, the superabsorbent resin 15 can absorb a large amount of water and form gel-like substances, so that the elastic bag 5 is extruded after swelling, and the swelling degree exceeds the gap between the elastic bag 5 and the ring sleeve 10 in the initial state, so that the pressure sensor 12 on the surface of the ring sleeve 10 detects the existence of pressure, at this time, the pressure sensor 12 triggers the controller to start the alarm 13 through a wired signal, reminding the staff to come over for maintenance, in the process of the staff coming over, the superabsorbent resin 15 forms gel-like substances, avoiding water dripping to the ground.

[0027] The elastic bag 5 filled with the superabsorbent resin 15 is installed on the surface of the electromagnetic valve 1, which can automatically issue an alarm when the electromagnetic valve 1 leaks, and can form gel-like substances to avoid water dripping to the ground.
