Abstract
A fuel gas automatic safety valve comprises a gas inlet end aligned screw pair (1), a gas transmission steel pipe (2), a gas inlet end tee joint (3), a manual valve (4), a gas outlet end aligned screw pair (5), a gas outlet end tee joint (6), a normally closed type electromagnetic valve (7), an electronic timer (8), a wire (9), a shading type photoelectric sensor (10) and a power supply (11). The fuel gas automatic safety valve is connected with a gas inlet pipe of a fuel gas pipeline through the gas inlet end aligned screw pair (1) and connected with a gas outlet pipe of the fuel gas pipeline through the gas outlet end aligned screw pair (5). The gas inlet end tee joint (3) and the gas outlet end tee joint (6) enable two parallel gas delivery pipes up and down to form a parallel structure, the manual valve (4) is arranged on the upper pipe, and the normally closed type electromagnetic valve (7) is arranged on the lower pipe, the electronic timer (8) and the shading type photoelectric sensor (10) are connected through the wire (9), power is provided by the power source (11), and the normally closed type electromagnetic valve (7) is connected with the electronic timer (8). The fuel gas automatic safety valve is simple in structure, convenient to install, and high in safety.
Description
Technical field
The present invention relates to a kind of safety valve, especially automatic safety gas valve.
Background technique
At present, combustion gas (rock gas or liquid gas) has been widely used in family kitchen, but because the fire accident that the combustion gas improper use causes is also more and more, main cause is the combustion regime that the owner has forgotten gas cooker, gas cooker does not generally have the dry combustion method function of automatically dying, and long-time dry combustion method is very easy to initiation fire.This automatic safety gas valve is simple in structure, and is easy for installation.Cardinal principle is with the active state of people in the sensor sensing kitchen, when the activity of people in the regular hour, internal induction was less than the kitchen, automatically sends alarm signal, and cuts off gas supply.
Summary of the invention
Based on above purpose, the present invention proposes a kind of automatic safety gas valve, comprise that inlet end is to silk 1, gas transmission pipe 2, inlet end threeway 3, manually-operated gate 4, the outlet side is to silk 5, outlet side threeway 6, normally closed solenoid valve 7, electronic timer 8, wire 9, shading type photoelectric sensor 10, power supply 11, by inlet end silk 1 is linked to each other with the gas pipeline suction tude, by the outlet side silk 5 is linked to each other with the gas pipeline steam outlet pipe, inlet end threeway 3 makes up and down with outlet side threeway 6, and two parallel pneumatic tubes become parallel-connection structure, manually-operated gate 4 is installed on the superincumbent pipeline, normally closed solenoid valve 7 is installed on the pipeline below, electronic timer 8 and shading type photoelectric sensor 10 connect by wire 9, by power supply 11 power supplies, normally closed solenoid valve 7 is connected by electronic timer 8.
Automatic safety gas valve of the present invention is simple in structure, and is easy for installation, safe.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Automatic safety gas valve, comprise that inlet end is to silk 1, gas transmission pipe 2, inlet end threeway 3, manually-operated gate 4, the outlet side is to silk 5, outlet side threeway 6, normally closed solenoid valve 7, electronic timer 8, wire 9, shading type photoelectric sensor 10, power supply 11, by inlet end silk 1 is linked to each other with the gas pipeline suction tude, by the outlet side silk 5 is linked to each other with the gas pipeline steam outlet pipe, inlet end threeway 3 makes up and down with outlet side threeway 6, and two parallel pneumatic tubes become parallel-connection structure, manually-operated gate 4 is installed on the superincumbent pipeline, normally closed solenoid valve 7 is installed on the pipeline below, electronic timer 8 and shading type photoelectric sensor 10 connect by wire 9, by power supply 11 power supplies, normally closed solenoid valve 7 is connected by electronic timer 8.
Working state has two kinds, and when manually-operated gate 4 was opened, gas pipeline became the normal open road, and combustion gas can continue supply; After manually-operated gate 4 was closed, combustion gas must could be exported through normally closed solenoid valve 7, because solenoid valve is Normally closed type, when solenoid valve was not switched on, gas pipeline was in and opens circuit.After having the people to enter the kitchen, after converting electrical signal to, the induced signal that shading type photoelectric sensor 10 obtains passes to electronic timer 8, and electronic timer begins timing and allows power supply 11 begin to normally closed solenoid valve 7 power supplies, and solenoid valve is opened, and combustion gas is passed through.If timer (for example setting 15 minutes) within the time of setting does not receive the new electrical signal of sensor, to the solenoid valve outage, solenoid valve recovers normally off to timer automatically, and gas pipeline becomes turnoff state; As people during in the kitchen, generally be in mobile state, this moment, timer continued to receive the electrical signal that sensor sends, timer whenever receives once, timer zero clearing reclocking only has like this as the people and leaves the kitchen after 15 minutes, and solenoid valve just can cut out to form and open circuit.But electronic timer 8 select tape warning functions, when solenoid closure, also can send warning reminding like this.
