Description
Technical field
The present invention relates to a kind of gas valve on gas utensil, particularly relate to a kind of gas valve with working state deixis.
Background technique
For the gas valve of gas utensil generally comprise have gas-entered passageway and outlet passageway valve body, be provided with the spool and a valve rod that have large fire hole and small fire hole in valve body, valve rod has the spring in valve body hold and keep the trend of moving.The top of valve rod can be connected with the knob be arranged on stove panel, during use, operable knob and control handle bar, general first pressing knob also rotates counterclockwise, movable valve plug can be with rotate counterclockwise, the fire hole on spool be connected with the gas-entered passageway in valve body, now, source of the gas can through gas-entered passageway, outlet passageway and from nozzle ejection, for gas utensil.
Existing gas valve does not all arrange the state-indicating function device being convenient to observe, see whether gas valve opens generally whether have flame by eye observation gas range, representing that gas valve is in the working state of combustion gas conducting if any flame, then representing that combustion gas is in non-on state as do not observed flame.In right real using process, combustion gas conducting may be there is but occur because of the situation of certain reason flame extinction, will judge by accident to people like this, think that gas valve is in closed condition, thus causing dangerous generation.
Although some gas cookers have safe deixis, this device is not generally set directly on gas valve, a kind of structure as disclosed in the patent No. Chinese utility model patent " gas valve status indicator " that is CN201410240261.0 (notification number is CN104006210A), comprise cabinet table surface and cupboard door, the outer surface fixed L ED tutorial light on cupboard door top, cupboard door is built-in with gas valve, in the fixing strong magnets in inboard, valve handle top, suction tude below gas valve is fixed with female bracket, dry reed-pipe is fixed on female bracket top, battery and resistance is fixed with in the middle part of female bracket.Tutorial light is connected battery by resistance with dry reed-pipe, and when after gas lockout valve, valve handle becomes 90 degree of right angles with valve, strong magnets does not contact dry reed-pipe, and LED light does not work.After gas valve is opened, valve handle and valve are in line, at this moment strong magnets aims at reed switch conduction, LED light is bright, represents that gas valve is opened, can use combustion gas, if disposable gas forgets closing valve, LED light just light yellow always, reminds people's throttle down, the generation averted a calamity with this.
A kind of structure as disclosed in the patent No. Chinese utility model patent gas cooker of green indicating lamp " band " that is ZL201320176873.9 (notification number is CN203286598U), comprise glass panel of stove, gas valve, ignition mechanism and thermocouple flame sensor, glass panel of stove has valve rod stretch out hole, gas valve comprises valve rod; Also comprise a single-chip microcomputer, sensitive switch and tutorial light, described single-chip microcomputer is connected with thermocouple flame sensor, and sensitive switch is connected with single-chip microcomputer and tutorial light; Valve rod is provided with driving lever, and driving lever coordinates with the spring bearer plate of sensitive switch; The curved lower surface being arranged on glass panel of stove of described tutorial light stretches out hole around the valve rod on glass panel of stove.Owing to adopting such structure, under turn clockwise by valve rod, while ignition electrode igniting, sensitive switch conducting, tutorial light is bright, and prompting gas valve is opened; When the induction of thermocouple flame sensor is less than flame, the switch module power-off of single-chip microcomputer, tutorial light extinguishes, and prompting closing gas valve, plays safety prompt function effect, be conducive to eliminating safe hidden trouble.
Existing safety indicating structure needs to arrange in addition, and structure is comparatively complicated, and cost is high.
Summary of the invention
Technical problem to be solved by this invention provides a kind of better combine with gas valve for above-mentioned prior art present situation and have the gas valve of working state deixis, this gas valve can indicate gas valve whether to be in unlatching aeration status effectively, and simple and reasonable.
