Abstract

The invention discloses an automatic valve closing device for leakage of a tap water pipeline, and relates to an article of daily use, in particular to an alarm device for safety closing of a valve in case of tap water pipeline leakage. The automatic valve closing device comprises a fixed shell, a motor and a control circuit, and is characterized in that the fixed shell is mounted on the tap water pipeline, the motor is mounted inside the fixed shell, a shifting fork is mounted on a shaft of the moor, the front end of the shifting fork is inserted into a rotating switch of the valve, the control circuit is mounted on a sidewall of the fixed shell, a control switch on the control circuit is disposed outside the fixed shell, the control circuit is connected with an alarm lamp, a receiver and the motor via conducting wires to form a loop, the alarm lamp and the receiver are mounted outside the fixed shell, the control circuit is further connected with an external power source, a plurality of tap water pipeline flow detecting and signal projecting machines are disposed on various sections of the tap water pipeline, and an anti-rust coating layer coats an inner wall of the valve. The automatic valve closing device has the advantages of novel structure, simplicity in processing, low cost, convenience in use, safety, reliability and the like.

Description

technical field [0001] The automatic closing device for a leaking valve of a tap water pipeline according to the present invention is designed as a daily necessities, specifically a safety closing alarm device for a leaking valve of a tap water pipeline. Background technique [0002] At present, there are more and more problems such as the leakage of running water pipelines and the failure of water taps to shut off, flooding after incoming water, and the loss of family property and public property. In view of the problems existing in the above-mentioned prior art, it is very necessary to study and design a novel automatic closing device for the leakage valve of the tap water pipeline, so as to overcome the problems existing in the prior art. Contents of the invention [0003] In view of the problems existing in the above-mentioned prior art, the purpose of the present invention is to study and design a novel automatic closing device for the leakage valve of the tap water p...
