Abstract
This utility model discloses a safety exhaust valve used in pressure cooker, comprising a valve which is arranged on a handle of a cover. The valve corresponds to the ventilation holes in the cover, which is characterized in having a control device in the valve that can control the open and close of the valve, the control device can start the safety exhaust valve without the need to use hands or other things to lift the valve, thus preventing the leaking steam burning the hands of the operator, and avoiding safety accidents.
Description
Technical field
The utility model relates to a kind of air bleeding valve, particularly a kind of safety exhaust that is applied on the pressure cooker.
Background technology
Safety exhaust is installed on the pressure cooker usually, and the safety exhaust correspondence is installed on the steam vent of pot cover.The present safety exhaust that adopts dead-weight valve body normally, when the pressure in the pressure cooker during less than the weight of safety exhaust self, steam vent is blocked by safety exhaust, and the gas in the pressure cooker can't leak; When the pressure in the pressure cooker during greater than the weight of safety exhaust, safety exhaust is by the gas jacking in the pot, and gas then releases from steam vent, thereby the air pressure in the pressure cooker is descended, so that the air pressure in the pressure cooker remains under the specified pressure.But, if the pressure in the pressure cooker need to be forced release less than rated pressure, at this moment can only be pulled upwardly valve body by staff or other object, Re valve body or the steam that leaks are scalded operator's hand easily like this, thereby cause the generation of security incident.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of need not directly contact the safety exhaust that valve body can carry out pressure release to pressure cooker.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of safety exhaust that is applied on the pressure cooker comprises being installed on the valve body that covers on the handle, and described valve body is relative with steam vent on the pot cover, it is characterized in that being connected with on the described valve body its control of turning device of control.
Preferred embodiment a kind of as the utility model, described control device comprises and is installed in the button that covers on the handle, support is installed on the button, be provided with in the support with by the briquetting of key contacts, the lower end of briquetting is equipped with metal hook, be set with back-moving spring on the metal hook, the bottom of described metal hook is connected with depression bar; By rotating shaft lever is installed in the described lid handle, an end of lever is positioned at the bottom of valve body, and the other end contacts with depression bar is movable.
As the improvement of the above-mentioned embodiment of the utility model, the bottom of described metal hook is provided with slide plate, and a side of slide plate is provided with the slideway that metal hook is resetted.
The beneficial effects of the utility model are: the utility model is connected with its control of turning device of controlled system on valve body, thereby when the pressure in the pressure cooker needs to force release less than rated pressure, need only safety exhaust be opened by control device, and need not be pulled upwardly valve body by staff or other object, thereby the steam that can prevent the valve body of heat or leak is scalded operator's hand, avoids the generation of security incident; Control device of the present utility model is provided with slide plate, slide plate is provided with and is beneficial to the slideway that metal hook resets, like this, when first time during pressing keys, metal hook slides in the screens of slide plate, the downward roof pressure lever of depression bar at this moment, thus make the other end of lever lever up valve body, gas releases from steam vent, to reach the purpose of pressure release; Pressing keys is once more unclamped button when making metal hook be in the downside of slide plate, and metal hook resets from being arranged in the slideway on the slide plate under the effect of back-moving spring.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a schematic perspective view of the present utility model;
Fig. 2 is the enlarged diagram at A place among Fig. 1;
Fig. 3 is a profile of the present utility model;
Fig. 4 is the enlarged diagram at B place among Fig. 3.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of safety exhaust that is applied on the pressure cooker disclosed in the utility model, comprise and be installed on the valve body 2 that covers on the handle, valve body 2 is relative with steam vent 3 on the pot cover 1, and when the gas pressure in the pressure cooker during less than the rated pressure of pressure cooker, valve body can rely on the weight of himself that steam vent is blocked, and the gas in the pressure cooker can't leak.
As shown in the figure, on valve body 2, be connected with its control of turning device of control, when the pressure in the pressure cooker needs to force release less than rated pressure, need only safety exhaust be opened by control device, and need not be pulled upwardly valve body by staff or other object, thereby the steam that can prevent the valve body of heat or leak is scalded operator's hand, avoids the generation of security incident.
With reference to Fig. 2, Fig. 4, Fig. 3, Fig. 4 are the enlarged diagram of a kind of preferred implementation of the utility model.Control device shown in the figure comprises and is installed in the button 5 that covers on the handle 4, support 6 is installed in button 5, be provided with in the support 6 with by the briquetting 7 of key contacts, the lower end of briquetting 7 is equipped with metal hook 8, be set with back-moving spring 9 on the metal hook 8, the bottom of metal hook 8 is provided with slide plate 13, and a side of slide plate 13 is provided with the slideway 14 that metal hook is resetted, and is connected with depression bar 10 in the bottom of metal hook 8.
As shown in the figure, by rotating shaft 11 lever 12 is installed in lid handle 4, an end of lever 12 is positioned at the bottom of valve body 2, the other end and depression bar 10 movable contacts.
Like this, when the pressure in the pressure cooker needs to force release less than rated pressure, downward pressing keys, at this moment metal hook slides in the screens of slide plate, the downward roof pressure lever of while depression bar, thus make the other end of lever lever up valve body, gas releases from steam vent, to reach the purpose of pressure release; The pressure release pressing keys once more that finishes is unclamped button when making metal hook be in the downside of slide plate, and metal hook resets from being arranged in the slideway on the slide plate under the effect of back-moving spring.
