Abstract

The utility model relates to the field of a gas cooker, which is a dual-purpose valve of timing and non-timing on the gas cooker. The utility model is composed of a cam, a pulley rod, a piston, a boosting spring, a valve body, a push rod, a valve core, etc. and is characterized in that the cam is driven by a timer to work according to laying burning time when timing is done, and the dual-purpose valve of the timing and the non-timing belongs to a normally opened valve when timing is not done. Timing work principle is that the cam is driven by the timer to work, and the pulley rod, the piston, the boosting spring and the push rod are pushed by the cam to open the valve core to make gas enter from an air inlet connected with a bolt hole and flow into a burning range by a valve chamber. The utility model has the function that the gas can be automatically closed after timing.

Description

Gas cooker is the non-timed dual purpose valve regularly

The utility model relates to the gas range field, is a kind of special valve of gas cooker.

At present, unlatching is only arranged on the control panel of gas range, close and regulate a switch of firepower coexistence, and time switch is not set.Therefore, the people just can not leave at aflame gas cooker, otherwise fire is merciless.

The purpose of this utility model is, provides a kind of gas cooker regularly and the dual purpose valve of non-timed, and to solve aflame gas cooker under the state of setting timing, the people can leave the problem of kitchen range; When not needing regularly, can recover often to open the dual purpose valve of present situation again.

Present design is such: it utilizes the work of timer driving cam, when cam work to the time of drafting, will block the combustion gas inlet passage automatically; State timer in the non-timed is not worked, and still presses the normal open state work of combustion gas.

The advantage of this design proposal is combustion gas under the state of setting regularly burning, closes main valve even you have forgotten, and also is unlikely to allow gas leakage, can stop to take place the phenomenon that utensil burns out.

Description of drawings:

Fig. 1 is this dual purpose valve timing reset status architecture schematic representation;

Fig. 2 is this dual purpose valve timing working status architecture schematic representation;

Fig. 3 is the position view of this dual purpose valve non-timed normal open state cam and roller arm;

Fig. 4 is the schematic representation of the another kind of structure of this dual purpose valve.

Referring now to above schematic representation, its feature is made following narration: Fig. 1 to this dual purpose valve structural representation shown in Figure 3, and it is made up of cam 1, roller arm 2, piston 3, boosting spring 4, seal ring 5, valve body 6, push rod 7, spool 9, seal ring 10, thrust spring 11, valve gap 12 etc.This valve is set in gas cooker, timer switch is installed on the control panel of gas cooker, timer is located in the control panel and is connected with cam, one end of cam 1 contacts mutually with roller arm 2, roller arm 2 roof pressures piston 3, are provided with boosting spring 4 in the piston 3, and the timing dual purpose valve combustion gas of normally open enters from the connecting bolt hole 13 of suction port, core chamber 14 through spool drains into air outlet bolt hole 8, the input gas cooker; The cam 1 of the dual purpose valve of normally open during the non-timed is the position that is in the inverse time logical 15 of roller arm 2.The gas cooker regularly another kind of structure of non-timed dual purpose valve is to be used for that seal ring is had etchant gas and a kind of special valve of being provided with, this valve is made up of cam 1, roller arm 2, piston 3, boosting spring 4, choke spool 16, valve body 6, valve rod 17, spool 9, thrust spring 11, valve gap 12 etc., is provided with choke spool 16 in valve body 6.

The timing working principle: first pass that combustion gas enters the burning kitchen range is to be introduced into air inlet connecting bolt hole 13, regularly initial cam 1 leaves the mouth that resets and begins to rotate (Fig. 2), roller arm 2 promotes piston 3 this moment, impel boosting spring 4 to promote push rod 7, make push rod 7 left ends and seal ring 5 be close to valve body 6 recessed shoulders, back down spool 9 simultaneously, be full of combustion gas in the core chamber 14, combustion gas is discharged from air outlet bolt hole 8.After the time of drafting finished, cam resetted again and gets back to reset mouthful (Fig. 1), and this timing working process has just been finished.Because the elastic force of boosting spring 4 is greater than the elastic force of thrust spring 11, so push rod 7 promotes spool 9 than being easier to, and just left the space between spool and the valve body, so cam resets comparatively timely, thrust spring 11 helps a power in addition, resets to close combustion gas and just realized.

The non-timed working principle: dual purpose valve is in normal open state during the non-timed, and promptly cam 1 is the positions that are in the inverse time logical 15 with roller arm 2, and leave certain core chamber 14 between valve body and the spool this moment, and only the location of cam and roller arm belongs to reverse position.

Another kind of double spool structure is used for having the gas of corrosive action to be provided with to seal ring, does not therefore establish seal ring in valve body 6, and choke spool 16 is set, and closing combustion gas and opening combustion gas is directly to be realized by closely cooperating of spool 9 and valve body 6.

Claims
