A gas valve closing method

Abstract

The invention discloses a gas valve closing method which comprises an antitheft door, wherein a spring bolt thrust lever is arranged beside a spring bolt frame of the antitheft door, the force application point of a lever arm of the spring bolt thrust lever extends into the spring bolt frame to be positioned in an extension path of a spring bolt when the antitheft door is closed, one end of a tensile force transmission line is fixedly connected to the resisting point of the spring bolt thrust lever, the other end of the tensile force transmission line is fixedly connected with the force application end of a valve closing lever beside a gas valve, an inclined wedge is arranged on the lower edge of a resisting arm of the valve closing lever, and the section of the inclined wedge is a smooth blocking surface; screwing force required by closing the gas valve is provided for a handle for opening the gas valve by a screw spring on a handle lever, and the handle is blocked by the section after the valve is opened. The method is characterized in that closing of a gas pipeline with the mechanism is implemented by the normal behavior of a person in closing the antitheft door in daily life, and by such a behavior, time when the spring bolt is pushed into the spring bolt frame is the same as a time period when the gas pipeline needs to be closed, so that the accident of gas leakage can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of gas use security, and in particular relates to a method for closing a gas valve. Background technique [0002] As we all know, because the gas valve is not closed when going out, there is a gas leak, and when the light is turned on when entering the door, it will cause an explosion, or the gas valve is not closed before going to bed, and accidents of poisoning and death due to gas leakage often occur. Although there are currently some ways to prevent gas leakage, the most common is to use gas alarm equipment, but due to greasy contamination and other reasons, the instrument often fails after being installed for a long time, and it is difficult to verify frequently. It is often not until something happens that the instrument fails. Therefore, when the gas leaks, the alarm is still a passive behavior, mainly relying on people to close the valve when the gas is not in use, but some people have poor memory and often le...

Although there are currently some ways to prevent gas leakage, the most common is to use gas alarm equipment, but due to greasy contamination and other reasons, the instrument often fails after being installed for a long time, and it is difficult to verify frequently. It is often not until something happens that the instrument fails. Therefore, when the gas leaks, the alarm is still a passive behavior, mainly relying on people to close the valve when the gas is not in use, but some people have poor memory and often leave the stove to do other things after boiling water or meals. The most dangerous thing is Running errands or going to bed without turning off the gas

Because in this case, either the person is absent or has fallen asleep, it is difficult to detect the gas leak in time, or there is nothing that can be done when it is discovered.
