Description

Energy-saving safe coal gas timing valve

The utility model relates to a kind of switch gear, particularly energy-saving safe coal gas timing valve.It is applicable to gas-fired device.

The jet of existing gas stove and gas water-heater does not generally adopt timer.Therefore in the daily life, many people are arranged when using gas stove or gas water-heater, often owing to the turn out the gas switch has been forgotten in artificial carelessness, and make the coal gas sustained combustion be directed at initiation fire, perhaps extinguish the back and do not cause gas poisoning because of jet closes at stove fire, the tragedy that causes casualties is given family's Jonah, also causes damage to national wealth.

The purpose of this utility model is to improve proposition and the energy-conservation coal gas timing valve of design safety at above-mentioned the deficiencies in the prior art.

Technical solution of the present utility model is that the employing timer is characterized in that timer and air valve are combined into one.

It is characterized in that the axis of timer and air valve are joined company and be combined into one.

It is characterized in that, air valve is made up of spool, valve body, spring, spring cap, backing pin, valve body is overlapping spool, spool and valve body are movingly, spring housing is being fixed by the spring cap, the backing pin that are contained on the spool on the spool, and two vents that are positioned at the spool both sides in the air vent on the spool and the valve body cooperate.

It is characterized in that block in the axis of the handle insertion timer of spool, valve body is fixed together by fixed card, screw and timer.

It is characterized in that, one of two vent that are positioned at the spool both sides in the valve body big one little.

It is characterized in that the air vent on the spool is a C shape opening

It is characterized in that the air vent on the spool is the U-shaped opening.

It is characterized in that the air vent on the spool is a D shape opening.

It is characterized in that the angle of swing of spool is 0-300 °.

Working principle of the present utility model is that utilization is widely used in timer Timing, the function regularly on the household electric appliance, and itself and air valve are combined, and is used for controlling the output of coal gas.Because joining with the spool of forming air valve by its axis, timer connects together, after timer is timed, timer is started working, the axis of timer will rotate according to certain speed, thereby the handle that drives jammed spool in the axis that inserts timer synchronously rotates, because valve body is fixed together by fixed card, screw and timer.Make that thus being contained in the valve body upper valve core does spin motion with respect to valve body.Like this, the defeated passage of coal gas that constitutes when two vents that are positioned at the spool both sides in air vent and the valve body on the spool are communicated is because the variation of the interior two vent relative positions that are positioned at the spool both sides of the air vent on the spool and valve body finally is closed.Thereby reach the timing of coal gas output, the purpose that regularly can control, realize the effect of energy-saving safe.Not working when timer is timer when closing, and at this moment the spool of air valve is in the position of the vent in the draught excluder, and air valve is a closed condition.The operating condition of hence one can see that air valve is controlled by timer fully, and in other words, the Push And Release of timer has just determined the Push And Release of air valve.

The utility model has the advantages that, novel structure is reasonable in design, adopt mechanical timer, need not power supply during use, easy to install, safe, energy-conservation, practical, use timer of the present utility model to control the service life of coal gas as required, realize that unmanned just can be according to the automatic supply that close source of the gas, the auto extinguishing blocked of the time of setting, prevent the unnecessary adventurous burning and the waste of coal gas, brought safety and convenient for people's life.

Below, describe embodiment of the present utility model with reference to the accompanying drawings in detail.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model is made up of timer and air valve.Timer comprises turn-knob 1, axis 2, time display panel 3, timing device 4, stop 6, stopper ring 7.Wherein, time display panel 3 is fixed on timing device 4 fronts, and axis 2 is contained on the timing device 4, and axis 2 one ends are furnished with turn-knob 1, and the other end and the air valve of timer by axis 2 joined to connect and be combined into one.Timing device 4 is furnished with stop 6, stopper ring 7, and stop 6 cooperates the stop that realizes timing device 4 with stopper ring 7.Timer can be bought from the market, only need join an end that connects with air valve to the axis 2 of timer and process, and promptly processes an axis groove 5 on axis 2, gets final product in order to block toward the handle 8 that inserts spool 9 wherein.Joining the air valve that connects one with the axis 2 of timer is made up of spool 9, valve body 12, spring 16, spring cap 14, backing pin 15.Wherein, spool 9 is contained on the valve body 12, valve body 12 is overlapping spool 9, spool 9 and valve body 12 are movingly, spring 16 is sleeved on stretching out on valve body 12 end outward of spool 9, fixing by the spring cap 14, the backing pin 15 that are contained on the spool 9, block in the axis groove 5 on the axis 2 of the handle 8 insertion timers of spool 9 and by axis groove 5.Valve body 12 is fixed together with the timing device 4 of timer by fixed card 11, screw 18.There are two vents 13 on spool 9 both sides that are positioned in the valve body 12.Wherein, a vent 13 is big, and another vent 13 is little.Two vents 13 that are positioned at spool 9 both sides in air vent 10 on the spool 9 and the valve body 12 cooperate.On valve body 12, install in its through hole when rotating when spool 9, will realize that air vent 10 communicates with two vents 13 that are positioned at spool 9 both sides in the valve body 12 and constitute the current path of air-flow, perhaps seal the current path of air-flow with respect to valve body 12.The convenient draw-in groove 17 that connects and fix with pneumatic tube is arranged on the outer wall of valve body 12, and the air vent 10 on the spool is C shape opening or is U-shaped opening or the air vent that is chosen as horn opening.As Fig. 5, shown in Figure 6, the air vent 10 on the spool also can be chosen as the air vent of D shape opening.The angle of swing of spool 9 is 0-300 °.
