Description

Gas-cooker button control valve

The utility model relates to the burnt gas switch and the control valve of the controller for gas of gas kitchen ranges, particularly a kind of gas kitchen ranges.

The burnt gas switch of existing household gas utensils comprises functions such as sparking, logical combustion gas and adjusting gas quantity size, it during its work earlier logical combustion gas, igniting again, as press turn-knob and promptly open air valve, change certain angle again, the general rotation about 90 degree, could light a fire, therefore ventilation and asynchronous time difference of causing of igniting, making partly, combustion gas leaks, polluted environment, be this knob type switch, particularly piezoelectric ceramics ignitor switch again, the overweight wearing and tearing that are easy to generate of generally exerting oneself, form chronic leakage or light a fire malfunctioningly etc., fault repair is more.Release a kind of embedded gas kitchen ranges on the market, burnt gas switch and Air-regulating valves branch are arranged, with minimizing fault and safe in utilization, but its structure becomes complicated, and consumptive material is many, makes cost higher.Produce many fields board gas-cooker etc. as board and Taiwan in the Japan product woods, their pipelines are more, structure is also unreasonable, as regulate the gas flow size and adopt plug-type driving lever to make the sealing-plug displacement, the contact friction damages sealing ring, the gas leakage problem takes place easily, also exists operation inconvenience to regulate ineffective problem simultaneously.

A kind of ventilation of the purpose of this utility model design is carried out synchronously with igniting, regulates the convenient and reliable nonabradable again gas-cooker button control valve of gas flow.

Design of the present utility model is, gas-cooker button control valve, it comprises the key switch of control combustion gas break-make, regulate the control valve of gas quantity size and between them together with pipeline, it is characterized in that key switch is by a push rod, one with push rod corresponding in the middle of the band on-off valve push rod, with one with push rod bottom mutually the microswitch of interlock form; Control valve is made up of regulating the qi flowing in the channels bar and the taper regulating the qi flowing in the channels spool that links to each other with the regulating the qi flowing in the channels bar and the valve body that matches with taper regulating the qi flowing in the channels valve core rotation.

The advantage of such scheme is that key switch both with the air valve on the push rod unlatching push rod, touches microswitch with the fine motion bar again and opens the ignition switch simultaneously, thereby realized ventilation and the problem of lighting a fire and carrying out synchronously.The valve body that adopts taper regulating the qi flowing in the channels spool to be rotatably assorted with it makes the combustion gas body be the hermetic seal state, and friction is little during rotation, can not produce the gas leakage problem, adjusting gas flow scope is big, flexible operation, easy to use, solve the switch of existing gas-cooker basically and regulated existing problem.

The 26S Proteasome Structure and Function of embodiment is described below in conjunction with accompanying drawing.

The button control valve of gas-cooker comprises the gas pipeline that key switch, control valve and they are connected, and key switch comprises burnt gas switch and electronic ignition switch.The on-off valve that burnt gas switch fixes by push rod (4), the push rod (6) relative with push rod (4), with push rod (6) middle part is formed, on-off valve comprises jump ring (7) elastic valve plate (8) and valve gasket (17), jump ring (7) and push rod (6) with elastic valve plate (8) and valve gasket (17) tight because of.The driving lever of interlock (1) is continuous mutually with push rod (4) by one for electronic ignition switch, forms and the synchronous microswitch (2) of button.Establish compression spring (5) in the push rod (4), push rod (6) bottom outer periphery compression spring (18), compression spring (18) bottom and breather pipe (19) offset, and top contacts with valve gasket (17).Fig. 1 table on-off valve is closed state with the ventilation mouth of pipe, and on-off valve is just in time sealed the path of combustion gas in breather pipe (19).When pressing lower push-rod (4), push rod (6) moves down, and on-off valve also moves down the breather pipe gas circuit and is opened, and push rod (4) left side sloping step tightens mutually with trip (3) simultaneously, keeps the on-off valve position constant relatively, keeps fuel gas path.Meanwhile, also drive the driving lever (1) that links with microswitch (2), make the contact of its compressing microswitch, connect circuit, igniting and logical combustion gas are carried out synchronously.Spring (15,18) is compressed to wait and resets, and when pressing push rod (4) again, sloping step is pushed trip (3) open, and spring (15,18) resets, and on-off valve also resets and closes gas circuit.

After on-off valve was opened, combustion gas entered control valve through communicating pipe (9).Control valve is made up of regulating the qi flowing in the channels bar (12) taper valve core (15) and valve body (16), regulating the qi flowing in the channels valve rod (12) fixes with the inverted draw cut (13) of taper valve core (15), peripheral compression spring (10) one ends and the banking stop (11) of regulating the qi flowing in the channels valve rod (12) joins, and the other end and taper valve core (15) are inconsistent.Referring to Fig. 3, cone valve is established axial center hole (27) and passage (25,26) radially, and upper and lower passage is connected with centre bore is orthogonal thereto.One perpendicular translot is arranged outside the upper vent hole (25), and gas circuit is unimpeded when regulating with assurance, improves sensitivity.Following passage (26) has the hole of dwindling and another centerline hole perpendicular, to regulate the size of little fire.

The section of Fig. 3 represents that partly 2-3 road different directions outgoing gas connection tube is arranged between regulation valve body and the escape pipe.Air inlet pipe is communicating pipe (9) through being divided into 3 road interfaces (14) of giving vent to anger behind the cone valve (15) among the figure, and expression can be made the interface of large, medium and small combustion head, and actual the use only needs 2 interfaces, can seal wherein 1.The air outlet adapter (14) of 2 combustion heads of Fig. 3-1 expression, it can be at grade, also can be not at grade, other 1 air outlet adapter was located at cone (16) bottom and was communicated with taper valve core (15) centre bore at grade Fig. 3-2 1 air outlet adapter of expression (14) and communicating pipe (9).

Fig. 4 is the structure vertical view of embedded gas-cooker, and it is 2 kitchen ranges, respectively with 2 button control valve controls.It is big fire that combustion head among the figure (21) is established the outer ring, and inner ring is little fire, and outgoing gas connection tube (14) is only with 2, and button control valve and kitchen range plane are 10 degree angle settings.Microswitch and key switch move simultaneously when pushing button, the electronic ignition part: fine motion driving lever (1) touches microswitch (2) closure, electric pulse ignitor (22) carries out pulse firing, after igniting pin (24) point catches fire, after induction chieftain (23) induction, signal is differentiated to circuit, if normal combustion then stops sparking; The key switch part: push rod (4) moves down promotion push rod (6) and moves down, on-off valve is opened, combustion gas enters communicating pipe (19 and 9) from air inlet pipe (20), control valve is regulated the flame of combustion head (21) to maximum or minimum, can clockwise or be rotated counterclockwise 120 and spends and get final product if transfer to little fire burns by big fire burns.

Gas inlet pipe shown in Figure 4 (20) is a beeline, has the advantage of saving pipeline, alleviates kitchen range weight and also can make kitchen range more succinct light by the represented below that directly air inlet pipe is connected to key switch of Fig. 5 if also will save pipeline.
