Background technique

Along with the raising of people's living standard, liquid gas, natural gas etc. has entered in the middle of people's the life, is very easy to daily life.But, because existing various gas supply pipelines and gas cooker all are not provided with timing function, can not control the time of air feed according to the time, make people when using gas cooker, can not at will leave, if really need leave, then must stop earlier air feed just can, otherwise the accident that very easily meets accident.

The model utility content

For overcoming above-mentioned defective, it is a kind of simple in structure that the purpose of this utility model is to provide, and can stop the inflammable gas timer of air feed by set time.

For achieving the above object, the utility model inflammable gas timer is made up of installation panel, air-supplying valve and mechanical wind-up timer; Installation panel is used for carrying, air-supplying valve and mechanical wind-up timer is installed; Air-supplying valve, the air feed air-supplying valve is provided with rotary valve rod, makes air-supplying valve be in the state of opening or closing in order to the Spin Control by valve rod; Mechanical wind-up timer, timer are provided with timer start-up control bar; Wherein, air-supplying valve and timer are installed on the installation panel, are provided with the control gear that air-supplying valve is closed when stopping with so that timer makes when starting air-supplying valve open between start-up control bar and rotary valve rod.

Wherein, above-mentioned control gear comprises: be installed on the start-up control bar and with the round turntable of start-up control bar concentric, be installed on the rotary valve rod in order to the spanner of twisting valve rod and with so that the Returnning spring that postrotational rotary valve rod resets; Wherein, on described round turntable, be provided with and the suitable arc-shaped recess in spanner end, make air-supplying valve be in open mode by the control spanner when rotating in some phase place, when the other phase place, then make valve be in closed condition by the control spanner at round turntable.

Wherein, above-mentioned control gear comprises: be installed on the start-up control bar and with the round turntable of start-up control bar concentric, be installed in the gear on the rotary valve rod in order to the twisting valve rod; Wherein, on described round turntable, be provided with 1 to 2 double wedge that is meshed with gear, make air-supplying valve be in open mode by the control spanner when rotating in some phase place, when the other phase place, then make valve be in closed condition by the control spanner at round turntable.

Adopt said structure, utilize the cooperation of timer, air-supplying valve, control gear and installation panel, can control opening and closing of air-supplying valve by timer, be convenient to the time of air feed is carried out timing controlled, can prevent the generation of contingency to greatest extent.

Fig. 3 is the schematic top plan view of another mode of execution of the utility model inflammable gas timer.

Embodiment

The utility model is further described below in conjunction with accompanying drawing.

To shown in Figure 2, the utility model inflammable gas timer is made up of installation panel 1, air-supplying valve 2 and mechanical wind-up timer 3 as Fig. 1; Installation panel 1, be used for carrying, air-supplying valve 2 and mechanical wind-up timer 3 are installed, it can be the control panel of gas cooker, also can be kind of the control panel of steam line Direct box, and it is difference with the difference of the employed position of the utility model inflammable gas timer; Air-supplying valve 2 can make air-supplying valve be in the state of opening or closing in order to the Spin Control by valve rod 21 for the various rotary valve rod inflammable gas air-supplying valves that are provided with; Mechanical wind-up timer 3, timer are provided with timer start-up control bar 31; Wherein, air-supplying valve 2 and timer 3 are installed on the installation panel 1, between start-up control bar and rotary valve rod, be provided with the control gear that air-supplying valve is closed when stopping with so that timer makes when starting air-supplying valve open, wherein, above-mentioned mechanical wind-up timer can be used timer on the products such as existing washing machine, microwave oven, and length regularly can design according to client's needs.

Wherein, above-mentioned control gear can be various ways, for example: be installed on the start-up control bar and with the round turntable 32 (as the employed round turntable of the timer on washing machine or the microwave oven) of start-up control bar concentric, be installed on the rotary valve rod in order to the spanner 22 of twisting valve rod and with so that the Returnning spring (not shown) that postrotational rotary valve rod resets; Wherein, on described round turntable 32, be provided with and the suitable arc-shaped recess in spanner end, make air-supplying valve be in open mode by the control spanner when rotating in some phase place, when the other phase place, then make valve be in closed condition by the control spanner at round turntable.

The working procedure of above-mentioned mode of execution is such: during use, rotation round turntable 32, arc-shaped recess on it promotes spanner 22 rotations, 21 rotations of 22 driven rotary valve rods of spanner, make air-supplying valve be in open mode, after round turntable 32 rotated to an angle, arc-shaped recess broke away from spanner 22, this moment, spanner 22 was pressed under the effect of Returnning spring on the excircle of round turntable 32, was in open mode to keep air-supplying valve 2; The continued rotation of round turntable 32 simultaneously is so that set timing; After the time of configuring, timer starts, round turntable 32 beginning counterrotatings, go to spanner 22 until arc-shaped recess and to contact, then spanner 22 under the effect of Returnning spring along with the rotation of round turntable 32 backward rotation, close air-supplying valve at leisure, air-supplying valve is closed when timer stops.As can be known, be example with common spherical valve from above-mentioned working procedure, the diameter of the degree of valve open and the length of spanner and round turntable has relation, and spanner is short more, the degree of opening of the big more then valve of the diameter of round turntable is then big more; Otherwise then the degree of opening of valve is more little, and this need adjust according to client's actual demand.

As the distortion of above-mentioned structure, above-mentioned as shown in Figure 3 control gear can also for: be installed on the start-up control bar 31 and with the round turntable 32 of start-up control bar concentric, be installed in the gear 23 on the rotary valve rod 21 in order to the twisting valve rod; Wherein, on described round turntable 32, be provided with 1 to 2 double wedge that is meshed with gear, make air-supplying valve be in open mode by the control spanner when rotating in some phase place, when the other phase place, then make valve be in closed condition by the control spanner at round turntable.

In summary, the utility model is by utilizing the rotation of the start-up control bar on the mechanical wind-up timer, by control gear air-supplying valve is opened dexterously, thereby reached the purpose that inflammable gas is regularly closed, can prevent the generation of contingency to greatest extent.
