Abstract

The utility model relates to a telescopic ignitor for a steam boiler, which adopts a direct current power supply E to be electrically connected with mutually insulated telescopic type bar conductors 3 on output ends (A[1], A[2]) after heated. The tail ends of the bar conductors 3 are healed to the distance that the ignition can be carried out in high pressure. A pressure lifting element is arranged on a circuit board and the bar conductors are arranged in an insulating cylinder 2. A power switch K is moved to the insulating cylinder 2. The telescopic ignitor for a steam boiler has convenient operation, portability, and safety.

Description

Telescopic ignitor for gas boiler

The utility model relates to a kind of extension type ignition of gas boiler device, belongs to the electronic striking device.

At present, each oil transportation multi-purpose station on the oil field, terminal and domestic gas boiler, the dining room gas stove mostly adopts the rod end to be stained with easy fuel oil with combustible, stretch into venting igniting in the stove after lighting, in ignition process, cumbersome, as run into windy day, utilize the open firing point stove easily to extinguish, simultaneously also dangerous.

The purpose of this utility model is to overcome shortcoming part of the prior art, is ignition of gas boiler device power supply, that make flexible conductor ends sparking after boosting with the direct current and provide a kind of.

The purpose of this utility model can reach by the following technical programs:

By power supply E, K switch, resistance R ₁, triode T ₁, transformer B ₁Form inductance connecting three point type and by diode D, capacitor C ₁, resistance (R ₂, R ₃), controllable silicon TEC, transformer B ₂Constitute secondary voltage rising circuit again, from voltage rising line output (A ₁, A ₂) being electrically connected the extension type stub of mutually insulated, excellent tail end closes up the distance that can strike sparks under high pressure, and voltage rising circuit, extension type stub are put in insulating cylinder, and switch moves on the cylindrical shell.

Can be in above-mentioned voltage rising line output 2 same model capacitor C in parallel ₂, stub closes up the porcelain cap that end is equipped with through hole.

The utility model is compared above-mentioned prior art and had following advantage: this igniter carries with easy to use, only stirs switch during use and just can finish a stove process, and is simultaneously safe and reliable.

Fig. 1, the 2nd, this igniter master vertical view.

Fig. 3,4, the 5th, insulating cylinder 2 is main on Fig. 1 looks complete section, a left side are looked, vertical view.

Fig. 6 is a telescopic stub schematic diagram on Fig. 1.

Fig. 7 be Fig. 6 upper conductor rod with the amplifying circuit output connect the end enlarged drawing.

Fig. 8 is porcelain cap 4 complete section figure on Fig. 1.

Fig. 9 is a voltage rising schematic circuit.

Below in conjunction with accompanying drawing will the utility model is described in further detail;

By shown in Figure 9, be the direct current schematic circuit that boosts.The utility model is at the direct current scheme circuit output (A that boosts ₁, A ₂) being electrically connected the extension type stub 3 of mutually insulated, excellent tail end closes up the distance that can strike sparks under high pressure; Boost scheme circuit plate, extension type conductor of direct current put 2 li of insulating cylinders, and wherein power switch K moves on the cylindrical shell.

Above-mentioned can be in voltage line output 2 the same model capacitor C in parallel that raise ₂, stub closes up the porcelain cap 4 that end is equipped with through hole 11.

By Fig. 3, shown in 5, insulating cylinder 2 can be made into and resolves into that (I, ∏) two parts constitute one by hole 6 usefulness screws.Insulating cylinder has power supply E chamber 5, wiring board chamber 10 and stub Room 13 3, and the dividing plate by with holes 9 is placed stub, and the first segment stub can be bonded on the hole.On the insulating cylinder, wherein 1 is the bolt fake, the 8th, and live on the power supply room and insert door.By shown in Figure 6, stub and wiring board output (A ₁A ₂) link be convex body, connecting hole is arranged on the convex body.By shown in Figure 8,2 minor details stub through holes 12 are also arranged on the porcelain cap 4, can be bonded as one.

Igniter operation principle (see figure 9)

By triode T ₁, resistance R ₁With oscillation transformer B ₁In induction coil L ₁, L ₂The inductance type oscillator of forming.When connecting power supply E(1.5V or 3V direct current) time, source current passes through R ₁Supply with T ₁Base current, T ₁The beginning conducting.L ₂Last generation induced electromotive force, it and supply voltage stack up further increases T ₁Base current.Treat that electric current is increased to T ₁Full fashionable, T ₁Multiplication factor reduces, L ₂Last induced electromotive force is also corresponding to be reduced.Thereby make T ₁End.T ₁By back oscillation transformer B ₁Inner magnetic energy discharges, and at this moment power supply can pass through L again ₁, R ₁Supply with T ₁Base current enters next cycle.

L ₃At B ₁In the time of vibration, induce the high pressure of 100V, after diode D rectification, voltage is stored in capacitor C ₁C is worked as at two ends ₁Both end voltage rises to R gradually ₂And R ₃Mid-point voltage, in the time of can triggering controllable silicon TEC, the TEC conducting makes C ₁On high pressure pass through B ₂First polar curve circle L ₁Form the capacitor discharge loop with controllable silicon TEC, simultaneously at B ₂Secondary coil on induce about 10,000 volts high-voltage pulse, as adjusting A ₁, A ₂2 distances can produce the discharge spark phenomenon.C ₂Be connected in parallel on pulse transformer B after two capacitances in series ₂On the inferior utmost point loop, purpose is to improve strength of discharge.

Ignition of gas boiler device exterior design can be made into the product of pistol type or other good looking appearance according to actual conditions and production technology means, also can be made into fixed igniter, is about to the ignition of gas boiler device and is fixed on ignition of the boiler place.
