Abstract

The utility model relates to an automatic closing timing valve for gas, which is composed of a valve body, a valve cover, a timer and a knob switch. The valve body is provided with a gas inlet pipe and a gas outlet pipe. The utility model is characterized in that a swing link used for opening and closing a gas pipeline is arranged in the valve body, the swing link is upward and downward swung along a jointed shaft of the gas pipeline, and swing of the swing link is controlled by a timer to realize timing automatic closing of gas. The utility model has the advantages of simple structure, easy and convenient use and reliable performance. The automatic closing timing valve for the gas is suited to be used by all gas ranges and especially suited to be installed and used by a household gas cooking range.

Description

The automatic timeing closing valve of combustion gas

The utility model relates to a kind of air valve, the automatic timeing closing valve of especially a kind of combustion gas.

Combustion gas is commonly used as a kind of clean fuel.Therefore the situation that accident appears in the fiery leakage gas of combustion usually appears putting out by water in normal double in addition other work of doing of people owing to heat up water when cooking, and gently contaminated air environment then gas poisoning seriously can take place even causes explosion of fire damp.Therefore people are heating up water when cooking, can not be wholeheartedly dual-purpose, even one family burns water flask, the time of doing a pot of cooked rice is generally all comparatively fixing, and can not be away from about it, the serious consequence of not so as easy as rolling off a log generation is so waste the many valuable time of people.

The purpose of this utility model is to provide a kind of combustion gas automatic timeing closing valve, and it is not only simple in structure, and can cut off source of the gas automatically in the time of setting effectively.

The utility model is achieved in that the automatic timeing closing valve of this combustion gas, by valve body, valve gap, timer and rotary switch are formed, valve body is provided with suction tude and steam outlet pipe, inboard by suction tude at the bottom of the inner chamber of valve body is provided with a boss, offering band the protruding of small through hole above the boss chews, small through hole in protruding the chewing is connected with suction tude, being hinged with one on the boss can be along the fork of hinging shaft swing, the upper tip of fork is protruding relatively chew be provided with one with the protruding cap stopper that matches of chewing, the cap stopper of fork and protruding opening of chewing, close by the timing shell fragment control that is fixedly mounted on the timer in the valve body, and the outer rotary switch of the center hole that the timing main shaft of timer passes valve gap and valve body is connected, and the timing main shaft of timer and the center hole of valve gap are sealing state.

The utility model is owing to only utilizing existing clock timer just can control the switching of fuel gas pipeline, so structure is very simple; Simultaneously because the clock timing technology is reliable, so can cut off source of the gas automatically in the time of setting effectively.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is a plan view of the present utility model.

Fig. 2 is the A-A line sectional view of the utility model Fig. 1.

Fig. 3 is the structural representation of looking up of the utility model Fig. 2 timer.

Describe concrete structure of the present utility model and working condition in detail below in conjunction with accompanying drawing.

With reference to Fig. 1～Fig. 3, the automatic timeing closing valve of this combustion gas, by valve body (6), valve gap (11), timer (14) and rotary switch (13) are formed, valve body (6) is provided with suction tude (1) and steam outlet pipe (2), inboard by suction tude at the bottom of the inner chamber of valve body (6) is provided with a boss (3), offer protruding the chewing (5) of a band small through hole above the boss (3), small through hole in protruding the chewing (4) is connected with suction tude (1), being hinged with one on the boss (3) can be along the fork (8) of hinging shaft swing, the upper tip of fork (8) is protruding relatively chew be provided with one with the protruding cap stopper (7) that matches of chewing, cap stopper of fork (7) and protruding opening of chewing, close by timing plectrum (9) control that is fixedly mounted on the timer in the valve body, and the outer rotary switch (13) of the center hole that timing main shaft (12) sealed type of timer is passed valve gap (11) and valve body is connected, its sleeve of timing plectrum (9) of timer is provided with return spring (10), in order to make things convenient for accurate set time, valve gap (11) is provided with the time scale table.

During use, at this moment the rotary knob switch is in definition status to the time of setting, and regularly plectrum (9) is opened, fork (8) is gone up the cap stopper (7) that matches with protruding chewing (5) and is opened, the combustion gas conducting, when the time to regularly at the end, plectrum (9) return under the effect of return spring (10) regularly, regularly plectrum (9) promotes fork (8) swing, make the cap stopper (7) on the fork (8) cover protruding chewing (5), close fuel gas pipeline, realize cutting off automatically combustion gas output; When not needing regularly to use, the counter-rotating rotary switch, clock spring is not worked, and promptly the time switch as electric fan is in " ON " position, the continuous conducting of fuel gas pipeline.
