Problems solved by technology

[0002] Most of the existing gas pipeline switches do not have self-protection functions. For example, the household gas pipeline is mostly connected with a rubber hose to the gas stove. Most households keep the gas switch in the normal open state. It is easy to cause poisoning, fire, explosion and other dangers, but the existing ga

Embodiment

[0016] The present invention is realized in this way: the gas detector 1 detects the gas content in the air near the gas pipeline. When the existing gas pipeline switch knob 8 is pressed down and turned counterclockwise, the gas pipeline is in an open state. There is a conductive piece 11 on the knob 8. When the conductive piece 11 is in contact with the current input reed 10 and the current output reed 9, the power supply 5 starts to provide power to the controller 3 and the gas detector 1. When the gas pipeline switch knob 8. When the reed 9 and the reed 10 are connected, if there is no leakage in the gas pipeline, the gas detector 1 cannot detect the gas near the gas pipeline, so the controller 3 controls the electromagnetic switch 4 not to be connected, and the circuit of the motor 6 is in the off state. open state.

[0017] If gas leakage occurs near the gas pipeline after the gas pipeline switch knob 8 is turned on, since all circuits have been connected at this time, th...

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a gas pipeline switch safety protection device. Background technique [0002] Most of the existing gas pipeline switches do not have self-protection functions. For example, the household gas pipeline and the gas stove are mostly connected by rubber hoses. Most households keep the gas switch in the normal open state. It is easy to cause poisoning, fire, explosion and other dangers, but the existing gas pipeline switch has the disadvantage that it cannot be automatically closed, so it is necessary to design a gas pipeline switch protection device that can automatically close, and automatically close the gas pipeline when there is a gas leak in the room. The main switch for the connection of pipes and rubber hoses to ensure safety. Contents of the invention [0003] To sum up, the purpose of the present invention is to provide a gas pipeline switch safety protection device...
