Abstract

A gas timing automatic safety closing valve includes a rotary button, a shell body and an air valve. The air valve comprises a valve core and a valve body. The valve is fixed in the shell body, and the shell body is provided with a timer. One end of the central shaft of the timer is installed with a timer rotary button, and another end thereof is provided with a pressure spring and is fixedly connected with the valve core. The valve core is provided with a ring-shape air inlet groove, and the valve body is provided with an air inlet hole corresponding to the ring-shape air inlet groove. The ring-shape air inlet groove is communicated with the air outlet hole of the valve body through the air outlet hole of the valve core. The utility model is a gas timing automatic safety closing valve with advantages of timing, automatic gas closing, simple structure, low producing cost with safety and reliability.

Description

The combustion gas timing automatic safety closes air valve

The utility model relates to a kind of combustion gas and closes air valve, and especially a kind of combustion gas timing automatic safety closes air valve, and use in the kitchen that extensively is useful for family, restaurant or the like occasion.

On the current gas range ignition mechanism of using, what have is equipped with automatic pass air valve, and its advantage is to take the dish out of the pot when outer when the water boil in the pot emits, and the water pouring can be closed gas on responding to tube head the time automatically.But the shortcoming of existence is and can not timing automatic closes gas, also because the induction tube head is unclean, also can influence the igniting effect of igniter sometimes.The Chinese patent communique discloses that a kind of application number is 99228156.3, name is called the utility model patent of " combustion gas safe and timing control valve ", and the pill of aluminium closed gas automatically when its advantage was that tracheae comes off.But the major defect that exists is: complex structure, and the manufacturing process complexity, the cost height does not have fixed cycle operator turn-knob dish outside housing, inconvenient operation at any time when the user uses.

The purpose of this utility model is intended to overcome above-mentioned the deficiencies in the prior art, proposes a kind of energy and close gas and combustion gas timing automatic safety pass air valve simple in structure, safe and reliable, low cost of manufacture regularly, automatically.

Realize the technological scheme of above-mentioned purpose: a kind of combustion gas timing automatic safety closes air valve, comprise turn-knob, housing and air valve, air valve is made up of spool and valve body, air valve is fixed in the housing, it is characterized in that: timer is set in the housing, central shaft one end of timer is installed regularly turn-knob, the other end is installed with stage clip and fixedlys connected with spool, have annular air inlet duct on the spool, valve body is provided with the inlet hole corresponding with annular air inlet duct, and annular air inlet duct communicates with air outlet hole on the valve body through the air outlet hole on the spool.

Regularly dial is set below the timing turn-knob.

Fixed plate is set in the valve body, and timer places in the timer housing and is screwed on fixed plate, and air valve is screwed on the fixed plate in housing.

Adopt technique scheme, compared with prior art, its beneficial technical effects is: 1, adopt timer construction, utilize timer center axle head to connect spool, the spool intermediate portion has annular air inlet duct, is rotated by timer spring band movable valve plug, can control out the length of gas time automatically.2, easy to operate: the outer design of housing at any time can fixed cycle operator the turn-knob lid, on housing, stamp scale, the user is length time as required in use, and the punctuate that turn-knob is covered is fixed the scale on the required time period, and the source of the gas of closing automatically of safety reach the purpose of stopping burning on time.Avoided people usually can not close fire in good time and taken place meal is boiled Jiao, medicine is endured Jiao, congee is endured Jiao, water dryouied even the generation of burning or the like accident at the bottom of the aluminum pot.3, safe and reliable: spool is done tapered, inserts in the cone shape hole valve body, and the spool top is established stage clip and controlled spool and move up, and guarantees that gas does not leak, and this is the assurance of safe usefulness gas.In addition, the spool taper, smooth surface drives with strong timer spring, has guaranteed the reliable smoothly of running and regularly has been provided with accurately.4, the utility model is simple in structure, ingenious, low cost of manufacture, and practicability is extremely strong.Be installed in during use between gas range and the reduction valve, be applicable to canned air, also be applicable to pipeline gas.The user is willing to accept, and reaches effect convenient, the safety material benefit.

Below by embodiment in detail, and its structure is described in detail in conjunction with the accompanying drawings:

Fig. 1 is a kind of structural representation of the present utility model.

Fig. 2 is the plan view (dial 17) of Fig. 1.

The drawing explanation: 1-is turn-knob regularly, 2-housing, 3-timer central shaft, 4-timer housing, 5-timer, 6-fixed plate, 7-spool stage clip, 8-spool, 9-suction tude, 10-valve body inlet hole, 11-spool vent, 12-valve body, the 13-steam outlet pipe, 14-annular air inlet duct, 15-valve body air outlet hole, the 16-air valve, 17-dial, 18-timer spring.

Embodiment: with reference to Fig. 1, a kind of combustion gas timing automatic safety closes air valve, comprise regularly turn-knob 1, housing 2, timer 5, spool stage clip 7 and air valve 16, air valve 16 is made up of spool 8 and valve body 12, timer 5 places in the timer housing 4, by fixed plate 6 usefulness screws timer 5 and air valve 16 are fixed in the housing 2, timer 5 is installed regularly turn-knob 1 by its timer central shaft 3 one ends, regularly the housing 2 of the below of turn-knob 1 is provided with regularly dial 17, the other end of timer central shaft 3 is installed with spool stage clip 7 and fixedlys connected with spool 8, spool stage clip 7 prevents gas leak, timer 5 drives central shaft 3 by inner timer spring 18 and rotates, rotate by central shaft control spool 8, have annular air inlet duct 14 and spool vent 11 on the spool 8, spool vent 11 1 ends communicate with valve body inlet hole 10 through annular air inlet duct 14, unslotted on the annular air inlet duct 14 partly is the gas area, pass of spool 8, valve body inlet hole 10 external suction tude 9, spool vent 11 the other ends communicate with steam outlet pipe 13 through valve body air outlet hole 15.

Working procedure: the regularly turn-knob 1 that moves in the direction of the clock, air valve ventilation when making the annular air inlet duct 14 of spool 8 aim at valve body vents 10.When timer 5 reaches preset time, timer 5 drives central shafts 3 revolutions by inner timer spring 18, when annular air inlet duct 14 turns over valve body inlet hole 10, enters and closes the gas area, and timer 5 quits work, and closes gas check valve 16 automatically.
