Problems solved by technology
[0004] Conventional devices generally required the use of motors and gears to close the valve, which was not only complicated in structure and high in manufacturing costs, but also required a lot of power to rotate the valve.

Embodiment Construction
[0027] The working principle of the present invention will be described in detail below in conjunction with the drawings.
[0028] figure 1 It is a top view of the automatic closing valve assembly according to the present invention.
[0029] The automatic closing valve assembly 1 is installed on a general gas pipeline 2. The automatically closing valve assembly 1 includes a valve body 14 with a handle 12.
[0030] Such as figure 2 As shown, the side of the valve body 14 is connected to the pipe 20. The pipe 20 is preferably vertically connected to the gas pipe 2, but its installation direction is not limited to this.
[0031] The pipe 20 has a sliding rod 22 inside. A plurality of zigzag protrusions 29 are formed on one side surface of the moving rod 22. The valve body 14 is also formed with a protrusion 19 that engages with the zigzag protrusion 29 of the moving rod 22. The moving rod 22 and the valve body 14 are engaged between the protrusions 19 and 29 to achieve linkage.

The present invention relates to an automatic shut-off valve assembly, and particularly relates to a valve assembly which comprises a valve body with a handle and can automatically shut off a gas valve. The valve assembly comprises the following components: a pipe which is connected with the valve body; a movable rod which is engaged with the valve body with sawtooth projections and reciprocates with a sliding mode in the pipe for switching the gas valve; an elastic means which performs an acting force in the pipe for closing the gas valve; a fixing component which overcomes the pushing forceof the elastic means and fixes the movable rod when the valve body is provided at an opening position; a separating part which separates the fixing component from the movable rod; and a control part which controls the separating part so that the valve body returns from the opening position to the closing position. As the movable rod moves through the elastic means, no dynamic force for rotating the valve is required additionally. Not only can energy be saved, but also the structure is simple. The manufacturing cost can be saved.
Description
Technical field [0001] The present invention relates to an automatic closing valve assembly that automatically closes a gas valve, in particular, to an automatic closing valve assembly that is automatically closed by an elastic device. Background technique [0002] In recent years, the use of gas, especially city gas, has been increasing. In addition to ordinary households, it is also widely used in facilities such as canteens. [0003] However, with the popularity of gas, safety accidents are also increasing. The danger of explosion or poisoning caused by gas leakage is very high. Regarding gas valves, people continue to develop new technologies that can prevent problems before they happen. Generally speaking, the most widely used device is to automatically close the gas valve through a timer after a preset time has elapsed or when a gas leak is sensed. [0004] In order to close the valve in the past, the device generally needs to use a motor and gear, which not only has a compl...
