Embodiment Construction

[0023] see Figure 1 ~ Figure 2 . The gas safety self-closing valve disclosed by the utility model is mainly used to automatically close the gas delivery channel when the gas delivery pressure is too low or too high, so as to avoid accidents. The gas safety self-closing valve includes: a valve seat 10 , an automatic closing valve 20 , a fixed seat 30 , a connecting rod set 40 , a braking device 50 , and a valve cover 60 . The valve seat is provided with a flow channel extending horizontally, the left end of which is a gas input end 11 , and the right end is a gas output end 12 . The gas output end 12 is provided with a gas switch 121 . The middle part of the valve seat 10 is provided with a valve slot 13 with an open upper end, and the valve slot 13 is in communication with the flow channel. The automatic closing valve 20 is arranged in the flow channel of the gas input end 11 of the valve seat 10 and can automatically close the flow channel of the gas input end 11 . The f...

Abstract

The invention provides a gas safety self-closing valve, which includes: a valve seat, a valve cover, a braking device, a connecting rod group, and an automatic closing valve. The middle part of the valve seat is provided with a valve slot with an open upper end. The automatic closing valve is arranged in the flow channel of the gas input end of the valve seat, and can close the flow channel of the gas input end. The connecting rod set includes a horizontal actuating rod, a vertical connecting rod and a horizontal sliding rod. The detent device includes a detent lever, a rubber membrane, a first spring and a second spring. The rubber diaphragm is fixed on the middle part of the braking lever. The valve cover is locked with the valve slot of the valve seat. The periphery of the rubber diaphragm is compressed between the valve cover and the valve slot. The horizontal movement of the horizontal sliding rod of the connecting rod group is driven by the raising and lowering position of the stop rod, so that the opening and closing of the automatic closing valve achieves the action of automatically closing the flow channel during low-pressure and high-pressure delivery.

Description

technical field [0001] The utility model relates to a gas safety self-closing valve, which can automatically close the flow channel of the gas when the gas is delivered at low pressure or high pressure. Background technique [0002] Whether it is domestic gas or industrial gas, it is transported to the user end by means of a pipeline. Users only need to turn on the gas switch to ignite and use it, which is extremely convenient. But gas is a fuel with a low ignition point, which has certain dangers. Therefore, it is necessary to avoid gas leakage in the air, so as to avoid sparks in life accidentally igniting the gas and causing a fire. [0003] The gas must be used within the appropriate output pressure range, so that the flame height can reach a safe level and can be used again. When the output pressure of the gas is too high, the flame will be sprayed, which is difficult to control, and it is very easy to burn the human body, or accidentally ignite the surrounding objec...
