Abstract
The utility model relates to a valve, and particularly relates to a micro-wave anti-theft alarm valve. The micro-wave anti-theft alarm valve is characterized in that a microwave detecting circuit composed of a loop antenna and a coil is connected with the input end of a radar detection module TWH9438; the output end of the radar detection module TWH9438 is connected with the input end of a radar scanning module TWH9249; the output end of the radar scanning module TWH9249 is connected with a base of a triode through a resistor; an emitter of the triode is connected with the cathode of a direct current power supply; a collector of the triode is connected with the anode of the direct current power supply through a relay alarm apparatus and a power switch; one end of a capacitor is connected with the cathode of the direct current power supply, and the other end is connected with the anode of the direct current power supply through the power switch. By adopting the technical scheme, the micro-wave anti-theft alarm valve has the advantages and beneficial effects of being economical and practical, and automatic to alarm.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of microwave anti-theft warning valve.
Background technique
At present, the stolen phenomenon of open-air various valves occurs often, causes very large loss not only for the valve owner, and brings impact can for people's production, life.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of microwave anti-theft warning valve is provided, when have the people when this valve with regard to automatic alarm.
The technological scheme that its technical problem that solves the utility model adopts is: circuit is by loop antenna, coil, radar type detecting module TWH9438, radar scanning module TWH9249, resistance, the relay system alarm, triode, electric capacity, power switch, DC electrical source forms, DC electrical source by power switch to circuit supply, it is characterized in that: the microwave sounding circuit that is comprised of loop antenna and coil links to each other with radar type detecting module TWH9438 input end, radar type detecting module TWH9438 output terminal links to each other with radar scanning module TWH9249 input end, radar scanning module TWH9249 output terminal links to each other with transistor base by resistance, the negative pole of transistor emitter and DC electrical source links to each other, transistor collector is by the relay system alarm, the positive pole of power switch and DC electrical source links to each other, one end of electric capacity and the negative pole of DC electrical source link to each other, and the other end links to each other by the positive pole of power switch and DC electrical source.The circuit original paper is welded in the circuit board and places the warning circuit shell.Valve valve rotating disc links to each other with valve core in the valve body by axle, is fixed with the warning circuit shell on the valve body.
Because adopt technique scheme, advantage and good effect that the utility model has are: economical and practical, automatic alarm.
