Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of promptly cutting for hazardous materials transportation vehicle
Disconnected valve automatic control device, including box body 1, be provided in box body 1 air inlet pipe 2, escape pipe 3, solenoid valve 4, pressure sensor 5,
The gas path pipe 85 of velocity sensor 6 and controller 7, one end of air inlet pipe 2 and quick action emergency valve connects, air inlet pipe 2 it is another
End is connect with pressure sensor 5 and solenoid valve 4 respectively, and solenoid valve 4 is also connect with escape pipe 3, solenoid valve 4,5 and of pressure sensor
Velocity sensor 6 is electrically connected with controller 7.
As shown in Fig. 2, quick action emergency valve is pneumatic emergency stop valve, including valve body 81, flap 82, valve rod 83, reset bullet
The lower end of spring 84 and gas path pipe 85, valve rod 83 is fixedly connected with the center of flap 82, and the upper end of valve rod 83 is mounted on valve body 81
In the pilot hole at top, reset spring 84 is mounted between 81 top of flap 82 and valve body, and gas path pipe 85 is arranged in flap 82
Lower end, gas path pipe 85 are also connect with external gas source.When quick action emergency valve is opened, filled from external gas source into gas path pipe 85
Gas, so that the air pressure in quick action emergency valve improves, flap 82 is extruded unlatching under the action of High Voltage；Do not have in quick action emergency valve
When having enough pressure, reset spring 84 drives flap 82 to restore to closed state under the elastic reaction of spring.
Velocity sensor 6 includes but is not limited to radar, GPS, infrared sensor, inertance element etc., as long as can be real-time
The sensor of detection Vehicle Speed both is within the protection scope of the present invention.
Since air inlet pipe 2 is connected to the gas path pipe 85 of quick action emergency valve, the air pressure and emergency cut-off in air inlet pipe 2
Air pressure in valve is always consistent, and pressure sensor 5 is connect with air inlet pipe 2, can air pressure in real-time detection air inlet pipe 2, use
In the switch state of detection quick action emergency valve.
Solenoid valve 4 is normally off, and air inlet pipe 2 is not connected to escape pipe 3 at this time；When solenoid valve 4 is open state, into
Tracheae 2 is connected to escape pipe 3.
Controller 7 is preset with speed threshold, according to GB7258-2017 " motor vehicle safe and technical specification ", this speed
Threshold values is not more than 5KM/h.
Working principle:
The switch state for the signal determining quick action emergency valve that controller 7 is transmitted according to pressure sensor 5, works as quick action emergency valve
When being in close state, controller 7 remains that solenoid valve 4 is closed；
When quick action emergency valve is in the open state, velocity sensor 6 detects that the travel speed of vehicle is not above speed
When bottom valve value, controller 7 keeps solenoid valve 4 to be closed；
Only when quick action emergency valve is in the open state, and velocity sensor 6 detects that the travel speed of vehicle is more than speed
When bottom valve value, controller 7 opens solenoid valve 4, at this point, air inlet pipe 2 is connected to escape pipe 3, due to air inlet pipe 2 itself with promptly cut
The gas path pipe 85 of disconnected valve is connected to, and the gas in quick action emergency valve is discharged by escape pipe 3 at this time, supports the valve in quick action emergency valve
The air pressure of valve 82 reduces, and reset spring 84 drives flap 82 to reset, and quick action emergency valve is closed, and realizes automatic control emergency cut-off
The purpose of valve；After solenoid valve 4 is opened, controller 7 passes through preset reset time, is again switched off solenoid valve 4, the preset reset time
It is (but being not limited to) 3 seconds, 4 seconds, 5 seconds.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
