Abstract
A gas timing air-break valve has a timer 14, a diaphragm 1 is arranged between a valve casing 20 and a valve body 19, a concave wheel 9 in the timer 14 is matched with a crank 8, the crank 8 passes through the valve casing and extends into a long hole 21 of a lifting pull rod 3, a positioning hole 18 of the pull rod is matched with a locker 6 in a fixed block 5, a convex rod 7 is arranged in the pull rod, and a bulge 17 of the convex rod extends into a guide groove 16 of the pull rod. The valve can be closed at random at regular time, can be controlled manually, and is convenient, practical and good in safety.
Description
The utility model relates to regularly ACV Air Cut Valve of a kind of combustion gas.
Now, gas appliance generally uses in a large amount of families in cities and towns.But in these gas appliances such as picture gas cooker, gas water-heater, general do not possess the function that can regularly stop the supple of gas or steam or regularly die according to user's wish, bring big inconvenience to the user, often take place to forget throttle down because of user's inadvertent or the interference of interim thing, cause the pot in food dryout, burnt, seriously also can burn out cookers such as pot, basin.
The purpose of this utility model is exactly to solve the deficiency that exists in the above-mentioned background technology, and provide a kind of and can close at any time or regularly close, combustion gas that Security is good ACV Air Cut Valve regularly.
To achieve these goals, the utility model proposes the corresponding techniques solution:
This combustion gas regularly ACV Air Cut Valve has a timer of being with knob, has barrier film between valve casing and the valve body, it mainly is that interior recessed the wheel with crank of timer cooperates, crank passes in the slotted hole that valve casing stretches into liftable pull bar again, locker in the positioning hole of pull bar and the fixed block cooperates, nose bar is housed in the pull bar, and its projection stretches in the guide groove of pull bar.

The local amplification assumption diagram of Fig. 2: Fig. 1.
The B of Fig. 3: Fig. 2 is to view.
Fig. 4: the relative position schematic representation of nose bar during normal ventilation.
Fig. 5: the relative position schematic representation of nose bar when regularly dying.
Fig. 6: lever and recessed fiting relation figure of taking turns during normal ventilation.
Fig. 7: lever and recessed fiting relation figure of taking turns when regularly dying.
Below with reference to drawings and Examples the utility model is done an explanation.
As shown in Figure 1 and Figure 2, the utlity model has a valve body 19, barrier film 1 between valve body 19 and valve casing 20, connect a pressing plate 12 by nut 13 in the center portion of barrier film 1.In valve casing 20, spring 2 is between pressing plate and positioning block 4; By the top spring with bump the locker 6 that pearl constitutes and be positioned at valve gap 5.Pull bar 3 runs through valve gap 5 and positioning block 4 and spring 2, briquetting 4, sealing gasket 1 successively.Respectively be provided with a guide groove 16 and positioning hole 18 in the both sides of tubulose pull bar 3, the nose bar 7 that has projection 17 is through in the pull bar 3.On pull bar 3, also have the slotted hole 21 (referring to Fig. 3) that cooperates with lever 8.Timer 14 is contained in outside the valve casing 20, and recessed in the timer 14 taken turns 9 and matched with the crank section of lever 8.Timer 14 comes set time by knob 5.
This timing ACV Air Cut Valve is not when working, and lever 8 is in parallel position, and pull bar 3 is positioned at extreme lower position (referring to Fig. 4, Fig. 6), and at this moment, the bottom end seal pad 3 of pull bar 3 is pressed on the vent of valve body 19 by the strength of spring 2, and combustion gas can not be passed through.
If in the time of need regularly closing source of the gas, come set time by the knob 15 that twists timer 14.At this moment, recessed 9 the cylindrical of taking turns contacts and turns round (referring to Fig. 7) with lever 8 always, and by lever 8 nose bar 7 jack-up (referring to Fig. 5) in the pull bar 3 is upwards oppressed locker 6, and makes stage clip 22 compressions.Simultaneously, the sealing gasket 23 of pull bar 3 bottoms breaks away from vent, and combustion gas can be passed through smoothly.When timer 14 ran to set time, recessed 9 the breach of taking turns just in time went to lever 8 places, and lever 8 can fall into this breach (referring to Fig. 6) automatically, and lever 8 is in parastate again.Because the effect of spring 2, positioning hole 18 breaks away from lockers 6, and pull bar 8 is positioned at extreme lower position again and seals vent by sealing gasket 23, promptly realizes the timing automatic function of dying.If when not needing regularly to close, only need mention the button 11 of pull bar 3 terminations, pull bar 3 to be located by positioning hole 18 by locker 6, sealing gasket 23 leaves vent can normal air feed.
The utility model has overcome the deficiency that exists in the background technique, by the interoperation of timer, lever, pull bar, spring and the dual double-action mechanism of sealing gasket, can arbitrarily realize regularly closing valve and without timer function, thereby reaches the purpose of safe usefulness gas.
