Problems solved by technology

[0002] Nowadays, pressure cookers are widely used in people's cooking utensils, whether they are used in households or in the catering industry, but at present, the control of this type of pressure cooker is realized by pressing the valve cover, but it cannot be adjusted at will, basically it cannot be adjusted
Within the allowable pressure range of the pressure cooker, the user can only adjust the pressure by changing the weight of the pressure limiting valve cover, which is impossible for ordinary people

Embodiment Construction

[0012] The structure of the control valve will be further described in detail in conjunction with the accompanying drawings:

[0013] The structure of the control valve can be roughly divided into a gas control part, a steam control part and an electronic control part. The gas control part is mainly composed of a solenoid valve 26, an O-ring 25, a valve body 5, a valve stem 8, an O-ring 9 and a nozzle 11. The steam control part is mainly composed of parts bonnet 7, valve body 5, diaphragm 6, valve stem 8, O-ring 9, spring cover 10, spring 12, spring sleeve 13, O-ring 14, and pressure adjustment screw 15. The electronic control part is mainly composed of parts band switch 3, cam 4, lock nut 1, cover 2, valve body 5, micro switch 19, micro switch 27, wire plug plate 29, ejector rod 23, spring 22, O-ring 20, Gasket 21 is formed.

[0014] Screw 28 fixes the micro switch 27 in the valve body 5 . The lock nut 1 fixes the band switch 3 on the cover 2 . The cam 4 is sleeved on the...

Abstract

A control valve for high-pressure automatic steam pot or stove is composed of gas control unit, steam control unit and electronic control unit. Membrane is installed between valve cover and valve body. There is cavity between valve cover and the membrane. The top end of valve rod is touched closely with the membrane. Valve cover has hole for communicating the cavity with outside of the valve body. A projector pin is installed at side of said valve rod. Its top end is in contact with top end of valve rod and its lower end is in touch with the leaf spring of microswitch. Nozzles, selection switch and wire jack holder are installed to the valve body. Its advantages are compact structure, high reliability, flexible control, and high adaptability.

Description

Technical field: [0001] The invention relates to a control valve for a gas cooker, in particular to a control valve for a gas cooker used to control a high-pressure gas cooker. Background technique: [0002] Pressure cooker is used more among people's cooking utensils now, no matter is all generally used in family or catering industry, but the control for this type of pressure cooker is realized by pressing valve cover at present, but can not adjust arbitrarily, basically can not adjust. Within the allowable pressure range of the pressure cooker, the user can only adjust the pressure by changing the weight of the pressure limiting valve cover, which is impossible for all ordinary personnel. Because the pressure cooker is only equipped with a pressure limiting valve cover when it leaves the factory. It is impossible for cooks to choose different pressures according to different cooking items and cooking methods to achieve the best cooking effect and save gas. Invention con...
