Embodiment Construction

[0020] The present invention will be further described below in conjunction with the specific embodiments of the accompanying drawings. (but not a limitation of the invention).

[0021] As shown in Figure 1, the gas leakage automatic cut-off and alarm device according to the present invention includes a gas sensor 1, an operational amplifier 2, a pulse trigger circuit 3, an automatic gas cut-off valve 4, an alarm trigger circuit 6, and an acousto-optic alarm circuit 7 and signal sending circuit:

[0022] When the gas leakage reaches a certain concentration, the gas sensor 1 and the operational amplifier 2 work to generate a control trigger signal;

[0023] Control the trigger signal all the way to make the pulse trigger circuit 3 work. After the pulse trigger circuit works, a pulse current is generated to timely and effectively control the gas automatic cut-off valve. When the gas leakage reaches a certain concentration, the gas source can be automatically and reliably closed...

Abstract

This invention discloses one gas leakage automatic switch and alarming device, which comprises gas sensor, computation amplifier, impulse trigger circuit, gas automatic switch value, sound and light alarm circuit and signal emission circuit, wherein, when the gas leakage amounts to certain degree, the gas sensor triggers the amplifier to generate control trigger signals to start the impulse circuit by one branch and other branch starts the alarm trigger circuit; the impulse trigger circuit controls the automatic switch valve to close the gas in certain degrees; alarm trigger circuit starts the alarm circuit and signals circuit.

Description

technical field [0001] The invention relates to an automatic cut-off and alarm device for gas leakage. Background technique [0002] The use of gas brings convenience to people, but because gas is an invisible and intangible gas, if it is used carelessly, sometimes the gas will leak and cause a safety accident. source for safety. Contents of the invention [0003] The purpose of the present invention is to design a gas leakage automatic cut-off and alarm device: once the gas content in the air exceeds the standard, the device will alarm in time and automatically cut off the gas source for safety. [0004] The present invention realizes the object of the present invention through the following technical solutions: [0005] The gas leakage automatic cut-off and alarm device of the present invention includes a gas sensor, an operational amplifier, a pulse trigger circuit, an alarm trigger circuit, an automatic gas cut-off valve, an acousto-optic alarm circuit and a signal t...
