Description

Timing valve of liquefied gas cooker

The utility model is a kind of timing valve of liquefied gas cooker, belongs to gaseous fuel kitchen range control device technical field.

Known and commercially available liquefied gas stove does not so far all have time-controlling arrangement, this just makes many users in use forget for some reason to close fire or other are for example heated up water accidentally, watch TV when cooking or be busy with other things and accident or the like to leave burning things which may cause a fire disaster and cause with the fire excessive, not only waste source of the gas, also dryout Hu Shui, burn out food and cooker, serious even cause and cause the people life property loss by fire.

The purpose of this utility model provides a kind of timing valve of liquefied gas cooker, and this timing valve can be the safety of liquefied gas cooker, and rationally using provides condition, can be the consumption of user's fuel saving, avoids the generation of fire and the life and property loss that causes thus.

The utility model is to realize like this, timing valve of liquefied gas cooker, it partly is made up of control valve (2) and timer (1) two, wherein timer (1) includes housing (1), knob (1.2), chuck (1.3) and have the bottom concave station (1.41) card pin (1.4), running by the breach (1.31) of chuck (1.3) and the separation and reunion keying timer between the card pin (1.4), control valve (2) is then by valve body (2.9), spool (2.8), have that the valve pocket (2.6) of air supply opening (2.61) and air inlet (2.62) and one end are connected with spool (2.8) concentric and can in valve pocket, form by free reciprocating valve rod (2.1), it is characterized in that described timer (1) is one by its housing (1.1) with control valve (2) valve body (2.9) and links to each other, the valve rod (2.1) that makes concave station (1.41) concentric of the card pin (1.4) of timer (1) be enclosed within control valve (2) is connected on the other end of an end with spool (2.8), so valve rod (2.1) stretches out valve body (2) valve pocket (2.6) and has had the radially step (2.2) of locating with closeding valve cavity (2.6) accent effect with an end of card pin (1.4) socket, valve rod (2.1) is gone up corresponding valve pocket gas outlet (2.61) and is located also to have a radially lantern ring type bridge (2.4) that is fixed on the wall of valve pocket chamber between step (2.2) and the spool (2.8), is with a spring (2.3) on the valve rod (2.1) between the above-mentioned step (2.2) and the bridge collar (2.4).Because as the air inlet (2.62) and the liquefied gas source appendix deferent of this its valve pocket of timing valve of liquefied gas cooker (2.6) of being made up of timer (1) and control valve (2) of providing of above-mentioned the utility model connect, air supply opening (2.61) links to each other with user's liquefied gas cooker air inlet pipe; Because valve rod (2.1) one ends are affixed with spool (2.8) concentric that opens and closes air inlet (2.62), the other end inserts in the concave station (1.41) of timer (1) card pin (1.4), so the chuck (1.3) of timer (1) can move by its breach (1.31) control card pin (1.4) and then control valve rod (2.1), realize the keying control of air inlet (2.62).Because timer has certain time control scope, and the flame size of gas-cooker all can be controlled, so can need preset service time before lighting combustion gas with the user when kitchen range of the above-mentioned timing valve of outfit uses for the user.When presetting service time, the knob (1.2) that only needs the user to rotate timer (1) points to the required time scale, the chuck (1.3) that is coupling with knob (1.2) promptly rotates thereupon, make its breach (1.31) thus rotation is moved push card pin (1.4) displacement under the circular arc of chuck (1.3), moves down by its step (2.2) compression spring (2.3) thereby promote valve rod (2.1), make the spool (2.8) of valve rod (2.1) lower end thus the air inlet (2.62) that thereupon moves down unlatching valve pocket (2.6) makes combustion gas pass through air inlet (2.62) that to enter valve pocket (2.6) be gas-cooker confession gas through air supply opening (2.61) again.The user can put gas firing, when the time loss by above-mentioned user preset finishes, breach (1.31) the revolution playback of above-mentioned chuck (1.3), card pin (1.4) upper end returns in the breach (1.31), valve rod (2.1) drives under spring (2.3) elastic force effect thereupon that spool (2.8) rises and the air inlet (2.62) of closeding valve cavity (2.6) again, interrupt gas source, and needn't close the gas source switch of the liquefied gas cooker that is using, realized the safe handling of kitchen range, avoided also having saved gas consumption for the user owing to forget the fire incident that may cause.

Give further description below in conjunction with specific embodiment shown in the accompanying drawing to timing valve of liquefied gas cooker of the present utility model.
