Abstract

The utility model mainly solves the problem that the existing gas valve has no function of automatic shutting off and provides a timing gas valve which allows for time setting through a timer and can be used with an upper valve to automatically shut off. The timing gas valve comprises a gas outlet, a gas inlet, a timing dial, a valve block, a timer, a valve, a seal ring and an internal gas pipe. The timing gas valve has the advantages of reasonable structure, simplicity in use, novelty, practicality, high safety, availability for regular shutting off and the like.

Description

A kind of timing gas valve

Technical field

Gas valve technical field under the utility model relates in particular to a kind of timing gas valve.

Background technique

Known, gas valve is the same equipment that Modern Family all can use, and its air outlet that is installed in the coal gas altar is located, and is mainly used in controlling the flow of coal gas.According to red net Changsha news on July 6, because the coal stove in the shop not to close, after she and daughter, son wake up from a sleep, the symptom of carbon monoxide poisoning appears one after another near Mrs Chen who opens breakfast shop the Mawangdui.Fortunately Mrs Chen oneself is supportting by force and is dialing 120 phones, because rescue in time, the mother and daughter is Survive the perils of life, and son also needs hospitalization.In daily life, be of common occurrence such as the above-mentioned example that causes poisoning because of gas leakage.And our existing gas valve does not possess the ability that automatically shuts down, so can not effectively avoid the generation of above-mentioned accident.

Summary of the invention

Deficiency for above-mentioned existence the utility model proposes solution.Its technological scheme is: a kind of timing gas valve of the utility model mainly is comprised of pneumatic tube in air outlet, suction port, timing dial, valve body, timing device, valve, seal ring, the valve.Timing device comprises mechanical timer and knob.

The technical solution of the utility model is to realize like this ground: the air outlet at valve body two ends links to each other with pneumatic tube respectively with suction port.Before the use, the user must set the service time of an expection in advance by the knob on the timing device.Set time can be read by the numeral that knob points to regularly on the dial.Valve installation is in the lower end of mechanical timer.When turning knob, mechanical timer can be with movable valve to rotate, thereby makes the interior pneumatic tube of valve open-minded, and combustion gas is delivered to the air outlet by suction port.In case after the time set, mechanical timer can start immediately, thereby reduce gradually the aperture of valve.When mechanical timer resetted, valve and seal ring were closed, and pneumatic tube is closed in the valve, and knob makes zero, and circulation is interrupted in combustion gas.

The beneficial effects of the utility model are:

A kind of timing gas valve of the utility model has rational in infrastructure, use simple, Nover practical, Security is good, the advantage such as can realize regularly closing.(adopted especially timing device to cooperate the design of valve, utilized timing device to set the realization time, valve can be realized again automatically shutting down in the cooperation, thereby has guaranteed personal safety).

Description of drawings

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is the schematic diagram of the plan view of a kind of timing gas valve of the utility model.

Fig. 2 is the schematic diagram of the side sectional view of a kind of timing gas valve of the utility model.

Schematic diagram when Fig. 3 is the use of a kind of timing gas valve of the utility model.

Fig. 4 is the schematic diagram of the vertical view cutaway drawing of a kind of timing gas valve of the utility model.

Among the figure, (1) air outlet, (2) suction port, (3) are dial regularly, (4) valve body, (5) timing device, 5(1) mechanical timer, 5(2) knob, (6) valve, (7) pneumatic tube, pneumatic tube in (8) seal ring, (9) valve.

Embodiment

In Fig. 1, valve body (4) is overlooked ovalize under the effect.Air outlet (1) and suction port (2) are separately positioned on the corresponding position of valve body (4) both sides.Regularly dial (3) is installed in the upper surface of valve body (4), is printed with equably time scale on it.Timing device (5) is installed in the valve body (4), and can combine with timing dial (3) on every side the function that realizes pre-timing.

In Fig. 2, timing device (5) comprises mechanical timer 5(1) and knob 5(2).Mechanical timer 5(1) be installed in the inside of valve body (4), it is that a kind of mechanical structure of utilizing realizes parts regularly.Knob 5(2) be installed in mechanical timer 5(1) top, it can come to realize regularly to mechanical timer by twisting action.Valve (6) is fixedly mounted on mechanical timer 5(1) the lower end, and can rotate with mechanical timer.

In Fig. 3, during use, pneumatic tube links to each other with air outlet (1), suction port (2) with (7).

In Fig. 4, pneumatic tube (9) is positioned at the inside of valve body (4) in the valve, and the position fixed installation is by a seal ring (8) therebetween.Seal ring (8) can and valve (6) be complementary, both can realize closure.The two ends of pneumatic tube (9) link to each other with suction port (2) with air outlet (1) respectively in the valve.

Claims

1. a timing gas valve is comprised of pneumatic tube in air outlet, suction port, timing dial, valve body, timing device, valve, seal ring, the valve, and it is characterized in that: described timing device is installed in the valve body; Described timing device comprises mechanical timer and knob.

2. a kind of timing gas valve according to claim 1, it is characterized in that: described valve is fixedly mounted on the lower end of mechanical timer, and can rotate with mechanical timer.

3. a kind of timing gas valve according to claim 1, it is characterized in that: size and the valve of described seal ring are complementary, and both can realize closure.
