Description
Technical field
The utility model relates to a kind of solar heating engineering protective device that leaks.
Background technology
In solar heating engineering no matter be the heat pipe pressure-bearing type, still vacuum tube is walked ability of swimming, require automaticity than higher, unattended duty, fully automatic operation, in case drainages such as circulating line explosion, heat collector are leaked, bombing occur, certainly will cause the waste of running off of a large amount of hot water, cause economic loss.
Summary of the invention
The solar heating engineering that the purpose of this utility model provides a kind ofly can overcome above-mentioned defective, guarantee the heat collecting engineering safe operation protective device that leaks.Specifically:
Comprise the check valve that is installed on the heat collector outlet side circulating line, it is characterized in that: a control valve is set on the circulating line of storage tank outlet side, on the circulating line between control valve and thermal-arrest group import, check valve and the storage tank inlet, a flow controller is installed respectively, and set up controller, its input connects the output of flow controller respectively, its output termination control valve.
The described solar heating engineering protective device that leaks; controller adopts relay; flow controller adopts fluid flow switch, and wherein the output of flow controller connects the control end of control valve, the coil L of the output relay termination of flow controller through the normally-closed contact K of relay.
The described solar heating engineering protective device that leaks; controller comprises computing comparator and controllable silicon; flow controller adopts fluid flow switch; wherein the input correspondence of computing comparator connects the output of flow controller; its output termination silicon controlled control end; the silicon controlled anode connects power supply, and its negative electrode connects the control end of control valve.
The described solar heating engineering protective device that leaks, control valve adopts motor-driven valve.
The described solar heating engineering protective device that leaks, control valve adopts magnetic valve.
The described solar heating engineering protective device that leaks is set up warning device, the control end of its input termination control valve.
Its operation principle is: detect water-flow signal by the flow controller that is installed on the circulating line, when leaking, two detected water-flow signals of flow controller are just inconsistent, control closed control valve by controller according to detection signal, and give timely warning.As when the circulation system remains static, do not leak if having on the whole circulation pipeline, two flow controllers that are installed on the circulating line are in normally open, the output signal unanimity, controller is failure to actuate, and control valve is failure to actuate, be in normally open, the output of alarm free signal; In case occur leaking, because two flow controllers are mounted on the circulating line between control valve and thermal-arrest group import, check valve and the storage tank inlet, its detection signal is just inconsistent, one has detected flowing water, and another does not then have, and output signal is inconsistent, controller action, the controlled signal at stop of control valve is avoided the continuation of leaking, simultaneously output alarm signal; In like manner, when the circulatory system is in flow regime, do not leak if having on the whole circulation pipeline, two flow controllers that are installed on the circulating line are in normally off, the output signal unanimity, and controller is failure to actuate, control valve does not have control signal also is failure to actuate, and is in normally open, the output of alarm free signal; In case occur leaking, the detection signal of two flow controllers is just inconsistent, one has detected flowing water, and another does not then have or be small and weak, and output signal is inconsistent, controller action, the controlled signal at stop of control valve is avoided the continuation of leaking, simultaneously output alarm signal, so just solved current solar heating engineering automaticity height, unmanned, caused the drawback that a large amount of hot water run off to be wasted, guaranteed the safe operation of whole engineering in case leak.
