Domestic gas and water valve safety monitoring and automatic closing device

Abstract

The invention relates to a domestic gas and water valve safety monitoring and automatic closing device, and belongs to the field of safety devices. A locking rotation disk with a locking notch and a locating protruding piece is arranged on a ball valve of the device, a spring energy storage assembly fixedly connected with an opening / closing handle of the ball valve is arranged, and an electromagnetic assembly with a telescopic core and a position detecting assembly are arranged near the locking rotation disk. During temperature, smoke and gas concentration detection or when a water valve water leakage sensor outputs a signal or when a closing button switch of the ball valve is pressed down, the telescopic core of the electromagnetic assembly contracts from the locking notch of the locking rotation disk, the opening / closing handle of the ball valve together with the locking rotation disk rotates rapidly to the valve closing position under the driving of the spring energy storage assembly, and a total gas inlet pipe or a water pipe is closed automatically; meanwhile, the position detecting assembly outputs a valve closing signal to a concentrated monitoring control box, and therefore the safety monitoring and the automatic closing functions of domestic gas and water valves are realized.

Description

technical field [0001] The invention belongs to the field of control or safety devices, and in particular relates to an operation control or release device for a general control valve of household gas or tap water in a resident's house. Background technique [0002] The safe use of water, electricity, and coal is related to the happiness of thousands of families. In many cases, when parents go to work and students go to school, there is no one at home, or only the elderly and children stay at home. In order to ensure the safety of personal and property, it is best to Turn off the main switch of water, electricity and coal. However, there will inevitably be times when people forget to turn it off. [0003] Regarding the safety of gas use, it has attracted the attention of many people in recent years, and various automatic closing valves and automatic closing devices have been invented or developed. For example, the authorized announcement date is April 13, 1994, and the auth...

Problems solved by technology

[0005] However, there are still many potential safety hazards in the above-mentioned technical solutions. For example, the closing of the valve is completed by the cooperation of the motor and the limit switch, and the electric spark generated by the motor will cause fire and explosion when the gas leaks.

In addition, some power supply inlets have leakage protection switches, which can automatically trip and cut off the power supply in case of failure, but the water and gas valves do not have automatic closing functions, which will bury hidden dangers for family safety.
