CN2132109Y - Gas extinguishing fire timing self-closing valve device - Google Patents

Abstract

The utility model relates to an extinguishing and timed self-closing valve device, which is used for gas-fuel cooking stoves, and particularly for liquefied petroleum gas cooking stoves and gas cooking stoves. With the device, a suite of gas-extinguishment signal generating components and execution components automatically closing a valve are added on the base of the prior common gas-fuel cooking stove. As a result, while in normal use, as soon as extinguishment causes gas evolution, the gas cooking stove can emit an operating signal a plurality of seconds after the temperature of the stove burner falls, and automatically cuts off and extinguishes the fire through the execution components. Simultaneously, the valve can also be shut off and the fire can be extinguished at definite time under the condition of no attendance, and likewise, in a certain defined time, the valve can be automatically shut off after the extinguishment caused by some reasons. The utility model has the advantages of simple structure, convenient operation and high reliability.

Description

Gas extinguishing fire timing self-closing valve device

The utility model relates to stopping working on a kind of gas kitchen ranges, particularly coal gas and the liquefied petroleum gas kitchen range, the regularly device of self-closing valve.

At present, steam stove such as coal gas, liquefied gas is universal day by day at home, but the problem to the flame-out gas that overflows is still unresolved so far, and such a word is all arranged on the gas kitchen ranges specification: kitchen range in use put out if put out by wind or drenched by water, should shut valve immediately, the mediation room air can rekindle after the gas of running out of is wandered away, though this mode is simple, but need the people often to watch, do not only bothering but also dangerous like this.

The purpose of this utility model just for provide can be when flame-out self-closing valve, again can be reliably regularly a kind of safety, the labour-saving device of self-closing valve.

The utility model is achieved in that on original general gas kitchen range basis; increase a main valve and signal generating part and self-closing execution unit flame-out, regularly self-closing valve; form cover protection automatically, device regularly, this device can send an actuating signal in the kitchen range flame-out back several seconds closes total valve by execution unit automatically.Also can send sound and optic signal simultaneously, prompting personnel note, in addition, this device also can be under nobody looks after situation, and the time of fixing cooks food, and then can close total valve automatically.

The utility model is described in further detail below in conjunction with property for illustrative purposes only shown in the drawings rather than determinate embodiment.

Figure one is the utility model outward appearance location drawing.

Figure two is longitudinal sectional drawings of a kind of concrete structure of the utility model.

Figure three is left views of figure two.

Figure four is vertical views of figure two.

Figure five is circuit diagrams.

With reference to figure one, figure two, figure three, figure four, figure five, stopping working here, regularly self-closing valve is by temperature-sensing element bimetal release (1), back-moving spring (3), spring stop piece (4), thin slice (5) with the main valve interlock, main valve (6), locking key (7), with thin slice (5) and the chain contactor (2) of locking key (7), electromagnet (8), support spring (9), battery (10), timer (11), circuit general switch (12) and shell (13) constitute, bimetal leaf (1) closure when normal temperature, be raised to critical-temperature and disconnect when above, critical-temperature is adjustable; Switch (2) is closure when main valve (6) is logical, disconnects when main valve (6) disconnects.Locking key (7) can move down, battery two to four joint all can, timer (11) can be designed as common wind-up timer, is provided with two position ON, OFF.

Open main valve (6) during use earlier; back-moving spring this moment (3) is stretched; thin slice (5) is rotated by 90 degrees; just pinned by locking key (7); support spring (9) to be compressed; switch (2) closure; light kitchen range then; when the kitchen range temperature is raised to critical-temperature when above; switch (1) disconnects, and then press master switch (2) and get final product if need to use protective device this moment; if kitchen range is flame-out suddenly because of certain reason; after several seconds, the kitchen range temperature drops to below the stagnation temperature, switch (1) closure; circuit is connected; thereby finish flame-out signal generating process, therewith relevant structure such as the switch (1) of process; switch (2); switch (12) is referred to as the flame-out signal generating part of this device.

Be right after flame-out signal generating process, after electromagnet (8) energising locking key (7) is inhaled down, total valve is under back-moving spring (3) effect, be returned to the closed position, switch this moment (2) disconnects, electromagnet (8) outage loses its reliss, locking key (7) resets under spring (9) effect, thereby finish self-closing valve implementation, member that process is relevant is as electromagnet (8) therewith, locking key (7), back-moving spring (3), thin slice (5) supports spring (9) all to be called the flame-out self-closing execution unit of device.

If in the time of regularly, timer can be beaten to the ON position, push certain hour, then the circuit auto-closing is finished the signal generating process.Regularly the time, timer can not beaten to the OFF position, contact disconnects, and do not participate in action, so timer also should be as one of signal generating part.

This device also can share with source of the gas total valve or other valves, and its position can change arbitrarily with condition, and back-moving spring (3) can be used clockwork spring instead; Suitably change all can be done with condition in shape, size and the fixed position of thin slice (5) locking key (7), electromagnet (8), switch (2).Bimetal release (1) is if two-way, and closure in the time of promptly between critical-temperature T one critical-temperature T ' is lower than T ' or is higher than T and all disconnects, and then can omit switch (2).

Clearly, the professional and technical personnel of affiliated technical field can be to described flame-out, and regularly self-closing valve is made many other changes and is no more than scope of the present utility model.

Claims (1)

1, flame-out, the timing self-closing valve door gear of a kind of combustion gas is characterized in that it has comprised flame-out signal generating part of being made up of switch (1), switch (2), master switch (12) and timer (11) and the automatic-closing valve execution unit of being made up of back-moving spring (3), thin slice (5), locking key (7), electromagnet (8), support spring (9).
