    • PURPOSE:To prevent the leakage of raw gas by quickly closing a safety valve when the burner unit fails to be ignited by providing a charging circuit with an auxiliary charging circuit consisting of an actuating solenoid and a parallel side line. CONSTITUTION:An auxiliary charging circuit 23 consisting of an actuating solenoid 10 and a parallel side line is disposed in a charging circuit 21. When an actuating member 4 is pushed, it moves back from the closed position A to the ignition position B, and when it returns to the open position C by releasing the push, a gas passage 5 is opened and at the same time an igniter 15 performs its function to ignite the burner unit 3. As the actuating member 4 returns from the ignition position B to the open position C, a switch 24 is caused to close to render the circuit 23 functioning. That is, in a case where the burner unit 3 fails to be ignited, the charging current of the charging circuit 21 is bypassed via the auxiliary charging circuit 23 to suspend the energization of the actuating solenoid 10. In this manner, the solenoid safety valve 9 is quickly closed as soon as the holding by the solenoid is removed, and an accidental release of raw gas is prevented.
    • 目的:为了通过向由充电电路组成的辅助充电电路和致动螺线管和并行侧线提供充电电路而使燃烧器单元不能点燃时快速关闭安全阀,防止原料气体泄漏。 构成:在充电电路21中设置有由致动螺线管10和平行侧线组成的辅助充电电路23.当推动构件4被推动时,其从关闭位置A返回到点火位置B,并且当 通过释放推压而返回到打开位置C,打开气体通道5,同时点火器15执行其点燃燃烧器单元3的功能。当致动构件4从点火位置B返回到打开位置 位置C,使开关24闭合,使电路23起作用。 也就是说,在燃烧器单元3不能点燃的情况下,充电电路21的充电电流经由辅助充电电路23旁路以暂停致动螺线管10的通电。以这种方式,电磁阀安全阀 一旦取消了螺线管的保持,9就快速关闭,并且防止了原料气体的意外释放。

    • A water heater is disclosed having a main burner for heating a heat exchanger and a standing burner, and is also provided with an electromagnetic safety valve which is opened by a manual operation member and which is kept in its valve open condition by the electric current from a thermocouple element exposed to the standing burner and a water pressure sensitive member such that it opens in response to a supply of water to the heat exchanger (that is, the water flow is turned on). Both the electromagnetic safety valve and the water pressure sensitive valve are interposed in a fuel passage connected to the main burner. A standing burner fuel passage is connected on one end to the standing burner and is connected at its other end to a point located in between the two valves. Additionally there is provided a control circuit which has a capacitor, a discharging circuit for the capacitor having a solenoid operating the electromagnetic safety valve, and a changeover switch adapted to be switched by the manual operation member for charging or to the discharging circuit for discharging. A subsidiary discharge circuit for the capacitor is further provided having a switch which is interposed therein, and adapted to be closed when the supply of water to the heat exchanger is on. The subsidiary discharging circuit is in parallel with the foregoing discharging circuit, and a resistance is interposed between the two discharging circuits. Thus, when the control switch is closed and the subsidiary discharging circuit conducts, the solenoid does not become actuated and the electromagnetic safety valve is closed.

    • Bei einer Steuerschaltung für Gäsbrenner mit einem Verbrennungsluftgebläse (FA) sowie einem Strömungsschalter (PS) zur Überwachung der Luftzufuhr ist das Gebläse (FA) in Reihe mit einer ersten Diode (D04) und dem Ruhekontakt (PNC) des Strömungsschalters (PS) an eine Wechselstromquelle (L, N) angeschlossen und dieser Reihenschaltung eine aus einem Ladekondensator (C05) und einem ersten Widerstand (R05) bestehende weitere Reihenschaltung parallelgeschaltet. Die Erregerwicklung eines Relais (RY2) liegt in Reihe mit einem elektronischen Schalter (Q02) parallel zum Ladekondensator (C05). Die Steuerelektrode des elektronischen Schalters (Q02) erhält ein vom Ladezustand des Ladekondensators (C05) abhängiges Signal. Nur wenn sich der Strömungsschalter (PS) anfänglich ordnungsgemäß in seinem Ruhezustand befindet, kann sich der Kondensator (C05) aufladen und ein den elektronischen Schalter (Q02) durchschaltendes Signal liefern und damit das Relais (R02) zum Ansprechen bringen. Dieses schaltet sodann über seinen Arbeitskontakt (NO2) das Gebläse (FA) ein. Sobald ein hinreichender Verbrennungsluftstrom den Strömungsschalter (PS) zum Ansprechen bringt, legt dieser über seinen Arbeitskontakt (PNO) das Gasventil (PV) an Spannung).
