Abstract
The utility model relates to a control device for low power bistable function electromagnetic valves and motor-operated valves with various calibres, which solves the problem that when the existing valve is in abnormal active state, the enactment state of the valve is unable to ensured, such as the open state or the close state. The automatic controller for a valve comprises a main controller circuit for receiving a line signal, a signal analysis and control circuit, an energy storage device and a valve drive circuit. The automatic controller for a valve can be arranged in the valve as well as outside the valve. The utility model can drive the valve action when accident supply suspension happens in the control valve or the broken circuit of the control signal occurs, which makes the valve converted to the required active state. The automatic controller for a valve belongs to protection function device and can avoid accident expanding and damage of the whole control system. A low-power consumption state is held when the valve is inactive. The utility model can be used for low powered bistable function electromagnetic valves and motor-operated valves with various calibers and is suitable for use or control of water or gas motor-operated valve and electromagnetic valve of various specifications.
Description
Technical field: the utility model relates to the small-power bi-stable function solenoid valve that is used for various bores and the control gear of mortor operated valve.
Background technique: at present, various bistable state control valves are divided into mortor operated valve and solenoid valve two big classes, and working principle is: energising is the opening of may command valve, closure afterwards, after valve event puts in place, power supply disconnects, and the valve attitude of remaining stationary is to satisfy the requirement of low power consumption work.
And the control valve that common gas meter with control function, water meter etc. use, only be kept perfectly at circuit, could control valve during proper functioning, when (being cut off as signaling line or power line) when unusual appears in circuit, then valve can't open or close, and it is out of control to form valve.
Summary of the invention: the utility model purpose is to solve existing valve when abnormal operating state, can't guarantee valve is placed the problem of specified states as opening or closing.
The utility model valve automatic controller, comprise valve driving circuit, it is characterized in that this valve automatic controller also comprises the external piloting control system device circuit that is used to send control signal, the control signal one tunnel of this main controller circuit output is sent energy storage device, to the memory device stored energy; Another road number of delivering letters is analyzed and control circuit, judges having or not of signal for it.
Energy storage device provides working power for signal analysis and control circuit, and provides valve event required energy for valve driving circuit.
When external piloting control system device stops to transmit control signal or signal letter when being cut off, signal analysis and control circuit can not receive control signal, promptly send pulse signal, the energy drives valve closing that utilizes energy-storage travelling wave tube to provide
This valve automatic controller can be assemblied in valve internal also can be assemblied in the valve outside.
The utility model advantage and effect: the utility model still can drive valve event when control valve accident power-off or control signal occur and opens circuit, make valve become the working state that needs and promptly open or close.This control valve belongs to a kind of protective function, can avoid the fault of a whole set of control system to enlarge and loss.When valve is failure to actuate, keep low power consumpting state.Can be used for low power bi-stable function solenoid valve of various bores and mortor operated valve, be applicable to the use control of water, gas mortor operated valve and the solenoid valve of all size.
Description of drawings:
Fig. 1, valve automatic controller theory diagram;
Fig. 2, valve automatic controller reference circuit figure.
Embodiment:
As shown in Figure 1, this valve automatic controller comprises valve driving circuit, it is characterized in that this valve automatic controller also comprises the main controller circuit that is used to send control signal.The control signal one tunnel of this main controller circuit output is sent energy storage device, to the energy-storage travelling wave tube stored energy; Another road number of delivering letters is analyzed and control circuit, judges having or not of signal for it.
Energy storage device provides working power for signal analysis and control circuit, provides action required energy for valve driving circuit simultaneously.
When master controller stopped to send control impuls or signaling line and is cut off, signal analysis and control circuit can not receive control signal, promptly send pulse signal, the energy drives valve closing that utilizes energy-storage travelling wave tube to provide.
This valve automatic controller can be assemblied in valve internal also can be assemblied in the valve outside.Its physical circuit is referring to Fig. 2.
Claims (2)
1, a kind of valve automatic controller, comprise valve driving circuit, it is characterized in that this valve automatic controller also comprises the main controller circuit that is used for the receiving lines signal, the control signal one tunnel of this main controller circuit output is sent energy storage device, another road number of delivering letters is analyzed and control circuit, energy storage device one tunnel connects valve driving circuit behind signal analysis and control circuit, another road directly connects valve driving circuit.
2,, it is characterized in that the valve automatic controller can be assemblied in valve internal and also can be assemblied in the valve outside according to claim 1 described valve automatic controller.
