A kind of foot-operated burnt gas switch
Technical field
The present invention relates to a kind of burnt gas switch, specifically, be to use a kind of foot-operated burnt gas switch in the food-beverage industry big fire gas stove.
Background technique
The big fire gas stove that in food-beverage industry, generally uses, the switch of its gas range is manual knob switch basically.The cook is in when culinary art, particularly cooking, and its working procedure is: after the moving switch ignition burning of hand-screw, panhandle is held in support on the other hand; Frequently dish in the pot is thrown, slice is held in another hand support, frequently dish in the pot is stirred, and freshens vinegar with salt; For grasping the duration and degree of heating, also frequently with the moving switch of hand-screw, the increase and decrease firepower is after dish is carried out; The dish sabot is served, and water flushing frying pan is clean again, and a working procedure finishes, and works on or closes fire.We notice, begin in the middle of the entire work process of cooking end from igniting, and gas range is to burn always; Particularly, dish washes clean this stage of frying pan when carrying out to water; The cook is anxious to serve the dish sabot, not freely, also inconvenient goes rotary switc to close fire with hand, in fact; The cook can not go earlier Guan Huohou to go sabot to serve yet, and what this stage gas range burning was caught fire has slatterned fully.According to experiment statistics, begin to the whole process of cooking end from igniting, the gas range burning fire is wasted more than 40%, i.e. and the effective rate of utilization of combustion gas is below 60%.In addition, manually knob switch also is easy to gas leakage or damages.The product that so far, can better solve this technical problem does not appear on the market as yet.
Summary of the invention
The objective of the invention is to overcome the shortcoming that the manual knob switch of big fire gas stove of existing technology exists, the foot-operated burnt gas switch of a kind of rational in infrastructure, easy to operate, safety durable, obvious energy conservation is provided.
The present invention is achieved through following technical proposals.
A kind of foot-operated burnt gas switch comprises switch base, switch valve, pedal stand, brake cable, it is characterized in that:
Said switch base is provided with installs aperture and support and switch valve and brake cable installation aperture; Shift fork is rack-mount through pin, and switch valve firmly is installed on the switch base with screw, the outer contact shift fork that corrects of the free travel of switch valve push rod; Brake string set is installed on the brake cable aperture.
Said switch valve is a middle pressure valve, is that the knob screw rod with middle pressure valve removes, and changes the burnt gas switch that threadless push rod promptly becomes roof pressing type into; Under the normality, spring outwards ejects push rod, and gas circuit is broken off; When the inside roof pressure of the stressed effect of push rod; Gas circuit is connected, and the stroke of the inside roof pressure of push rod is big more, and gas circuit is opened just big more.
Adjacent base of the low side of said pedal stand and high-end adjacent base and end face are provided with the aperture; That the gear plate is provided with is little, in, big third gear firepower regulates draw-in groove, the both sides, lower end are provided with the aperture; The big adjacent base of pedal one end is provided with the aperture, and the other end is provided with two pedal ears, and two pedal ears are provided with the aperture; Little pedal one end is curved to declivity, and the other end is upwards straight curved, and little pedal is provided with two pedal ears, on the two pedal ears and between be provided with the aperture; The gear plate is installed in the high-end pedal stand through axle; On the axle on gear plate both sides axle sleeve is installed; Stretch out the two ends construction opening pin of the axle in aperture, high-end adjacent base; The high-end vertical plate washer that construction opening spring between the high-end vertical plate washer of gear plate and pedal stand, its elastic force remain gear plate and pedal stand is the amorph gesture mutually.Big pedal one end is installed in the low side pedal stand through axle; Stretch out the two ends construction opening pin of the axle in aperture, the adjacent base of low side; The little pedal two pedal ears of corresponding placement in the two pedal ears of the big pedal the other end; Be installed together through the brake cable pin, the brake cable pin one end construction opening pin that the pedal ear of big pedal is outer, the high-end end face aperture of pedal stand is equipped with the hollow adjusting screw rod and the locking nut of brake cable.
Said brake cable one end places in the brake cable running-on on the switch base; The core head passes return spring, is fixed on the shift fork, and the brake cable the other end places in the hollow adjusting screw rod of high-end end face of pedal stand; The core head passes brake cable pin lateral aperture, through screw rod core is fastened on the brake cable pin.
Installation of the present invention and debug process: switch base is installed on the stove seat of big fire gas stove through screw; Pedal stand places on the other floor of stove seat; Hollow adjusting screw rod through brake cable and locking nut are regulated the length of brake cable; Thereby make the gear plate corresponding obtain little, in, big third gear firepower, under the normality that gas circuit is closed, because the effect of return spring on the switch base; Brake cable up draws brake cable pin and big pedal and little pedal, make pedal ear one end of big pedal be suspended from the gear plate little, in, big third gear firepower regulates on the draw-in groove.
Working procedure of the present invention and principle: during work, step on big pedal, the pedal ear one of big pedal corrects on the little fiery draw-in groove that is stuck in the gear plate; While brake cable pulled down; Shift fork interlock on the switch base up spurs, and shift fork is with the inside roof pressure of push rod, and gas circuit is connected; Igniting, the little fire burns of big fire gas stove; Step on big pedal again, the pedal ear one of big pedal corrects on the moderate heat draw-in groove that is stuck in the gear plate fire burns in the big fire gas stove; Step on big pedal, the pedal ear one of big pedal corrects on the big fire draw-in groove that is stuck in the gear plate the big fire burns of big fire gas stove; Step on little pedal, little pedal backs down the draw-in groove of gear plate, obtains the firepower adjusting thereby just can increase and decrease gear.Large and small pedal is stepped on together, just can obtain electrodeless firepower and regulate, but pin is once leaving Guan Huoliao.
Know that by above the burnt gas switch that the present invention adopts is that middle pressure valve changes the roof pressing type burnt gas switch that forms for a short time, be not easy gas leakage or damage.Use the present invention; The cook is in the middle of the culinary art working procedure; Very convenient with pin operation firepower, particularly when dish is carried out, leave just Guan Huoliao again but just large and small pedal is stepped on together; So just avoided waste, promptly practiced thrift the fuel of useless combustion fire of this stage dish sabot and water flushing frying pan useless combustion fire of clean this stage.According to experiment, use the present invention, almost stopped the waste of the useless combustion fire of gas range, the effective rate of utilization of combustion gas is more than 95%.The present invention is rational in infrastructure, easy to operate, safety durable, obvious energy conservation.
