Abstract

PURPOSE:To enable retaining the valve in its shut-off condition in any trouble on the control circuit in such a way that two sets of relay circuits which are energized by means of driving signals of the valve are inserted in a control circuit for a solenoid closing valve to be used for gas machinery, or another. CONSTITUTION:Two sets of relay driving circuits 12, 13 are installed for a driving signal generating circuit 11 in a control circuit for a solenoid valve 25, and common terminals C, C' for their relays 20, 21 are connected to each other. In such a constitution, even if either transistor 14, or 17 may be involved in any trouble, and condition of conduction is generated between their collectors and emitters, or either between terminals (a) and c or between (a') and c' of the relay 20 or 21 is deposited and becomes remaining closed, so far as remaining transistor or relay may be normal, there is no instance that the solenoid valve may be its opening condition.

Particularly in gas appliances, when gas is supplied or cut off using a solenoid valve, it is extremely dangerous for the solenoid valve to remain open due to the above-mentioned irregularities. Figure 1 shows this conventional example. When the drive signal from the drive signal generation circuit 1 is applied to the base of the transistor 40 via the resistor 2, the transistor 4 becomes conductive and the coil of the relay 5 is connected to the base of the transistor 40. An exciting current flows, which closes the relay contact and drives the solenoid valve 6. Here, resistance 3 is
If there is no drive signal, one transistor 4 is surely turned off. In such a conventional device, for example, if the transistor 4 is connected and the lever emitter is short-circuited, or if the a-c contacts of the relay S are welded and remain closed, the solenoid valve is always open. It becomes.

Regarding the operation when each of the above components is 1, now,
If either transistor 14 or Fi 17 fails or #'i' breaks down, the collector-emitter becomes conductive, or either terminals i and c or l' and c' of relay 20 or 21 become conductive. Even if the solenoid valve is welded and remains closed, as long as the remaining transistors or relays are normal, the solenoid valve will not open, as is clear from its circuit configuration. In addition, the collector-emitter of the transistor 14 and 17 may be cut off, or the terminals of the relay 20 or 21 may be disconnected.
If either C or b'-c' is welded, a drive signal will be generated because the drive signal generation circuit Kii power is being supplied, but the 1. Since there is no closed SI between Otori' and C', power is not supplied to the solenoid valve.1. Furthermore, if the capacitor 27 is short-circuited, no power is supplied to the drive signal generation circuit, and if the capacitor 27 is open, the drive signal is generated at the moment the relays 20 and 21 switch. The power supply voltage applied to the circuit can no longer be maintained, the drive signal disappears, and the circuit returns to its initial state.

An explanation of what happens when an abnormality occurs in each of the above components is as follows.
This occurs when one component on the right side of the chair fails or breaks, but the probability of two parts failing or breaking at the same time is extremely small, so this is rarely a problem in practice. %L3゜As explained above, the solenoid valve drive device of the present invention is driven by a drive signal generation circuit, a pair of relay drive circuits operated by this drive signal generation circuit, and a pair of relay drive circuits. a pair of relays whose common terminals are connected to each other; a solenoid valve which is connected so that the valve is opened when the common terminal and normally open terminal of the pair of relays are respectively closed; and a drive signal. It consists of a generating circuit, a relay, and a power source for driving each solenoid valve, so
If a predetermined component fails or is destroyed, the solenoid valve is operated to close, thereby improving the safety of the system.
