Description
The utility model relates to the valve on a kind of stove or the kitchen range, specifically a kind of liquid, gas control valve that uses the cooking stove of novel liquid fuel.
At present, the liquefied gas cooker control valve can be controlled liquid gas flow, and the flare after the burning of energy regulator solution gasification, makes the user easy to use, safe.But use in recent years, the hybrid fuel of a kind of novel alcohols, hydro carbons, alkanes etc.This novel liquid fuel, its performance are volatilizations, inflammable.But Volatile Gas concentration is low, can not directly it be lighted, and in order to uses such as heating, must at first allow this type of liquid fuel heating itself, just can make the volatilization gas of this kind fuel light use.Like this, utilize this novel liquid fuel, just must produce a kind of outflow that can control flammable liquid and at first light a fire, can control the novel cooking stove control valve of the outflow of combustible gas behind the heated volatile again, and guarantee that it normally uses under certain pressure in order to burning.
The purpose of the utility model is to provide a kind of flammable liquid of can controlling to flow out to society, can control combustible gas outflow and energy impulse again and light a fire high voltage bearing cooking stove control valve automatically.
The utility model is such: it comprises, base plate, is fixed on combustible gas control system, pulse ignition switch and the support regulated by the turn-knob valve rod of band gas valve core in the valve casing on the base plate, retractable turn-knob valve rod, the valve casing; And the gas valve core in the combustible gas control system and valve casing to be being threaded, its two also be provided with sealing mechanism; The position that is lower than the combustible gas control system in the valve casing also is provided with the flammable liquid control system of being handled by the turn-knob valve rod.When the user pushes away the turn-knob valve rod when valve rod is contracted inward inward, pulse ignition switch is connected.Simultaneously, turn turn-knob valve rod is opened combustible gas control system and flammable liquid control system, and flammable liquid flows in the burning basin of burner.Because pulse switch is connected, and external pulse igniter is lighted flammable liquid in burning basin.Then, and then make the combustible gas burning and heating is provided.After the user decontrols hand, the turn-knob valve rod is resetted outward, this moment, the turn-knob valve rod was finished the control to flammable liquid, and the turn of turn-knob valve rod still can turn and the gas valve core of valve casing to be threaded, and controls the size of heating flare with this flow of regulating combustible gas.Because gas valve core and valve casing are being threaded, so this spool can adapt to bigger air pressure.Sealing mechanism on the gas valve core guarantees that combustible gas stream does not leak to burner.Such control valve has been realized the outflow and the control of combustible gas, has also realized the outflow and the control of flammable liquid simultaneously, and can be high pressure resistant, does not leak and igniting automatically.
Such valve, its combustible gas control system can be formed by the gas valve core of being regulated by the turn-knob valve rod that is threaded with valve casing in the air admission hole in the valve casing, venthole, the valve casing with by the sealing mechanism that the sealing ring at gas valve core front and rear portion, annular screw on the rear seal circle constitute.The turn of turn-knob valve rod driven gas valve core in valve casing along screw thread rotation, it advanced or retreat, both realized the stepless control of combustible gas flow, make gas valve core high pressure resistant again.And the flammable liquid control system can and be fixed on liquid spool on the turn-knob valve rod by the coil tension spring of the sealing ring at inlet opening, fluid hole, liquid spool, liquid spool front and the rear portion of valve casing bottom, the multiple resilience spring that is inserted in the liquid spool, turn-knob valve rod inner end and promotes alignment pin and form.When the turn-knob valve rod pushes away inward, the coil tension spring compression, when pulse ignition switch is connected, the upper end that the lifting alignment pin on the inboard turn-knob valve rod of base plate has inserted the liquid spool.When the turn of turn-knob valve rod, promote alignment pin the liquid spool is mentioned.Flammable liquid directly flows to fluid hole from inlet opening like this.When user's hand was decontroled the turn-knob valve rod, coil tension spring was upheld, and the lifting alignment pin on the turn-knob valve rod is flicked from the liquid spool (flow to the some fire pot by fluid hole again, lighted by pulse igniter).And the back-moving spring on the liquid spool is with the liquid valve core reset.Because the effect of sealing ring, when the liquid spool was opened, flammable liquid was only to the fluid orifice flow; When the liquid valve core reset, flammable liquid is trapped in outside the inlet opening.And pulse ignition switch can be by the insulating trip that is fixed on the plate outer side, and fixed touching plate and the movable contact spring, relief spring and the spring base that are fixed on the turn-knob valve rod are formed.The effect of relief spring is both to have guaranteed that the lifting alignment pin on the turn-knob valve rod inserted liquid spool upper end, thereby opens the liquid spool, can guarantee that again the movable contact spring on the turn-knob valve rod can touch fixed touching plate, thus the make pulse igniter.Several screws are separately fixed at valve casing and support the inside and outside both sides of base plate.
Description of drawings:
Fig. 1 is the utility model general structure schematic diagram (broken section)
Fig. 2 is the utility model schematic diagram (an existing literal note)
Below in conjunction with accompanying drawing the utility model is described.The user pushes inward turn-knob valve rod 21, turn simultaneously, and the movable contact spring 18 on the turn-knob valve rod contacts with fixed touching plate 17 on the base plate 13, thereby has connected external pulse igniter.Simultaneously, the lifting alignment pin 22 on the turn-knob valve rod is mentioned liquid spool 8; Gas valve core 25 also contracts backward and opens along screw thread 4.At this moment, the coil tension spring 23 of turn-knob valve rod inner end and back-moving spring 7 compressions that are enclosed within on the liquid spool.Owing to liquid spool rear portion is provided with sealing ring 10, liquid flows directly into fluid hole 9 from inlet opening 12, flows into the burning basin burning then and does not have leakage.Meanwhile, after the flammable liquid burning heating of the flammable liquid in the reservoir in burning basin, gasification rapidly.Combustible gas after the gasification flows to venthole 24 by air admission hole 2, directly flows to the usefulness of the burner of burner in order to the burning heating.Because screw thread and the sealing ring 5 at rear portion and the effect of annular screw 6 on the gas valve core have guaranteed that gas valve core is high pressure resistant and air tight.When the user decontroled hand, the elastic force of coil tension spring 23 resetted the turn-knob valve rod outward.At this moment, promote alignment pin and leave the liquid spool, the back-moving spring on the liquid spool makes the liquid valve core reset.Because there is the effect of sealing ring 11 liquid spool front, makes flammable liquid stop to flow into inlet opening.But and the turn-knob valve rod still turn regulate gas valve core, thereby reach the purpose of stepless control flare.When the turn-knob valve rod was twisted to smallest point, gas valve core withstood the sealing ring 3 of front, makes combustible gas stop to flow into air admission hole fully, and flare disappears, and heating stops.Whole use finishes.Insulating trip 16, relief spring 19 and spring base 20 guarantee pulse igniter switch operate as normal.Fixed screw 15 fuses valve casing 1 and support 14.
