Abstract
The utility model discloses an indoor leakage protection device, which comprises a rectifier power circuit, an alarm circuit and a indicator light circuit; and is characterized in that the device also comprises a subminiature liquid level switch circuit and relay contact switch circuit; the subminiature liquid level switch circuit is made of a group of liquid level switches S 1, S 2 in series and a testing switch S t; the relay contact switch circuit is made of the normally closed contacts S 3, S 4, S 5 respectively connected in series with the electromagnetic valve coils V 1, V 2, V 3; the circuits are bridge connected with the anode and the cathode of the power; wherein, the subminiature liquid level measuring device and the electromagnetic valve are arranged on the pipes of the tap water incoming household and/or the water inlet and outlet of the heating system. In the circuits, the relay coil is connected in series with the subminiature liquid level switch, the relay is interacted with the electromagnetic valve, any leakage of the tap water and the heating system will cause the prompt response of the electromagnetic valve and the sound-light alarming device. The utility model is characterized in ingenious reaction and working safely and credibly, and can be used for residential household and public buildings.
Description
Technical field
The utility model relates to room heater, the tap water protective gear that leaks.
Background technique
Room heater, tap water leak, cause damage not only for oneself property, can give also downstairs that resident family causes damage, so that cause that neighbourhood's dispute, the generation of this phenomenon have been of common occurrence, though people are always in complaint and appealing, but because the quality of pipe fitting and valve member is low, it is untimely that pipeline is installed and keeped in repair, indoor leaking, the disaster of water logging seven armies is with increasing intensity daily, has almost become a kind of persistent ailment.In some special places,, also can result in greater loss as library, archives etc.
Summary of the invention
The purpose of this utility model just provides a kind of protection, in time detects automatically after room heater, tap water leak generation and leaks, and closes the terminal valve of tap water inlet valve and heating installation automatically, makes property loss be reduced to the minimum protective gear that leaks.
The working principle of this device is after indoor leaking, experience water level signal by the liquid-level switch that is installed in indoor correct position, the normally opened contact of liquid-level switch disconnects, the relay outage, the electromagnetic valve coil energising of the import and export pipeline of fresh water inlet ductwork and heating installation is closed, and dashes the tragedy of family thereby avoid causing leaking.The alarm warning of sounding simultaneously.
Technical solution of the present utility model is achieved in that
A kind of indoor protective gear that leaks comprises rectification power circuit, and warning circuit and warning light circuit is characterized in that also comprising miniature liquid-level switch circuit and relay contact switch circuit, and described miniature liquid-level switch circuit is by the liquid-level switch S of one group of serial connection
