Problems solved by technology

However, due to the small rotation angle (that is, 90°), it is difficult for users to control the size of the fire, and they can only rely on bending over to observe, which is not a good user experience

Embodiment Construction

[0061] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0062] In the present invention, unless stated to the contrary, the used orientation words such as "up, down, top, bottom" generally refer to the directions shown in the drawings or refer to the vertical, perpendicular or gravitational directions The terms used to describe the mutual positional relationship of the various components mentioned above.

[0063] For the gas valve in the prior art, there is a narrow bandwidth for adjusting the fire power, and the synchronization adjustment of the fire power in the inner, middle and outer ring fires has not been realized, so it is difficult to grasp the size of the fire power, and it is necessary to bend down to watch...

Abstract

The invention discloses a gas valve which comprises a valve body, a valve element and a plurality of nozzles. The valve element is pivotally arranged in a valve cavity of the valve body, the valve body is provided with a gas inlet runner and a distribution runner, the gas inlet runner is communicated to a hollow cavity of the valve element, a surround fire hole is formed in the outer circumferential wall of the valve element and comprises a communication fire hole communicated to the hollow cavity, the distribution runner comprises a distribution runner start hole formed in the circumferential wall of the valve cavity, gas sequentially passes the gas inlet runner, the hollow cavity, the surround fire hole and distribution runner and is distributed into the nozzles, the valve element is sequentially rotated to a maximum fire position and a minimum fire position from a closed position along a sparking rotation direction, fire tendency of each nozzle is gradually adjusted to minimum fire tendency state from a maximum fire tendency state, and the rotation angle of gradually-changed adjustment of the fire tendency is not smaller than 60 degrees. According to the gas valve, same maximum fire tendency and same minimum fire tendency of each ring can be adjusted, the angle range of synchronous adjustment of the gas valve is wide enough, and the gas valve is more humanized in design.

Description

technical field [0001] The invention relates to the field of gas valves, in particular to a gas valve. Background technique [0002] In domestic gas cookers, gas valves are usually used to control the cut-off and opening of gas and to regulate the gas in the pipeline, and the gas valve has good control characteristics and closing and sealing performance, which ensures the safe use of the gas cooker. [0003] Conventional gas valves mainly have three gear positions, which are 0°, 90° and 180° in the counterclockwise direction (along the ignition rotation direction), respectively. The size of the flame can be controlled by adjusting the corresponding gears. Among them, the 0° position is the closed position of the gas valve, that is, the initial position; the 90° position is the maximum fire position; the 180° position is the minimum fire state. In addition, when the rotary gas valve is rotated from 90° to 0° or 180°, the fire gradually decreases, while at 180°, the outer rin...
