Embodiment Construction

[0020] image 3 It is an explanatory diagram of the first preferred specific embodiment of the present invention, Figure 4 The electronically operated timer used by the valve assembly of the present invention is shown.

[0021] like Figure 4 As shown, the valve assembly according to the present invention includes a timer 1, which electronically presets the operating time to control the length of time the valve is open. In this preferred embodiment, the valve assembly comprises a motor 11, which operates according to signals from the timer 1, a rod 13, which rotates around a rotating shaft 23 placed in the middle of the rod 13, and a valve sensor 15 which monitors the valve open / closed state and a valve 17.

[0022] A pin 19 is fixed to one side of the motor 11 and a protruding member 21 is formed at the end of the rod member 13 close to the motor 11 . When the motor 11 is activated, the pin 19 rotates and pushes the protruding part 21 of the lever 13 causing the lever 13...

Abstract

The present invention relates to a valve assembly equipped with an electronic timer to control the length of time a valve is opened. A valve assembly comprising a timer to electronically predetermine the operation period, a motor having a pin fixed on to one side operates based on a signal from the timer, a valve sensor 15 which is turned on or off by the rotation of the lever member and monitors open / close status of the valve and a valve having a home formed at the valve cap, and a winding spring which is secured onto the main body of the valve and a valve cap connected to the knob to perform the open / close functions of the valve and other end is fixed onto the inside of a valve cap to push the valve cap in the direction of a closed position of the valve as the lever member moves. The valve assembly according to the present invention provides safer way to use a gas fueled cooking device and allows more precise control of valve system.

Description

technical field [0001] The present invention relates to valve assemblies, such as gas valves, and more particularly to a valve assembly having an electronic timer which precisely controls when the valve is used and the state of the valve while in use. Background technique [0002] Generally, many families use a gas cooker for cooking, and a gas pipeline is used to connect a gas cooker such as a gas cooker and a gas source such as a gas storage tank. The gas line should be equipped with a gas control valve to cut off the gas flow to the gas stove. There is a spring in the bonnet, which prevents the knob of the gas control valve from turning accidentally, causing the gas path to open. To open the gas passage, the knob pushes down on the spring and rotates 90°. To close the valve passage, the knob is turned 90° in the opposite direction. When the knob is in the closed position, the spring pushes the knob outward to a position where the knob is prevented from turning freely. ...
