Abstract
The utility model relates to the gas extinguishing system vessel valve of interruptible price start and stop.At present, want shutdown system that gaseous extinguishing agent in bottle can only be waited to discharge when conventional vessel valve works could run by halt system.The utility model comprises valve body, it is characterized in that arranging piston rod in described valve body, and the top of piston rod arranges spring and piston, the top of described valve body arranges suction port, suction port connecting valve intracoelomic cavity, suction port place arranges safe pressure ring and safe plug screw, and the bottom of safe pressure ring arranges rupture disk.The utility model can shutdown system anywhere or anytime, and persistency can also control the on off state of vessel valve.Do not need to discharge extinguishing agent when changing system unit.Thus reduce the cost and the utilization ratio of extinguishing agent.
Description
Technical field
The utility model relates to the gas extinguishing system vessel valve of interruptible price start and stop.
Background technique
At present, conventional vessel valve working principle is through inlet charge extrusion spring band moving valve, thus punctures blowout disk to be held open state.That is when gas extinguishing system normally runs, vessel valve is opening state all the time, and wanting shutdown system that gaseous extinguishing agent in bottle can only be waited to discharge could run by halt system.
Model utility content
The utility model is for the problems referred to above, a kind of gas extinguishing system vessel valve of interruptible price start and stop is provided, make vessel valve can not only shutdown system anywhere or anytime, and persistency can also control the on off state of vessel valve, do not need to discharge extinguishing agent when changing system unit, thus reduce the cost and the utilization ratio of extinguishing agent.
For this reason, the utility model takes following technological scheme, the gas extinguishing system vessel valve of interruptible price start and stop, comprise valve body, it is characterized in that arranging piston rod in described valve body, the top of piston rod arranges spring and piston, the top of described valve body arranges suction port, suction port connecting valve intracoelomic cavity, suction port place arranges safe pressure ring and safe plug screw, and the bottom of safe pressure ring arranges rupture disk.
The upper end of described valve body is nested with pressure cap, and the joint of pressure cap and valve body arranges O RunddichtringO.
The bottom of described piston rod sets gradually trim ring, seal ring and flow guiding nut.
Between the inner side of described valve body and piston, seal ring is set.
The utility model is when inflation inlet air inlet, and rupture disk explosion, upwards, vessel valve starts piston rod.Close when starting gas, vessel valve valve inner extinguishing agent can upwards be given vent to anger, and drive piston rod upwardly, to seal gas can not pour off in vain from air outlet, thus Sustainable Control gas switch.
The utility model can shutdown system anywhere or anytime, and persistency can also control the on off state of vessel valve.Do not need to discharge extinguishing agent when changing system unit.Thus reduce the cost and the utilization ratio of extinguishing agent.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is worm's eye view of the present utility model.
In figure: 1. the pressure cap 2.O RunddichtringO 3. seal ring 4. piston 5. spring 6. piston rod 7. trim ring 8. seal ring 9. flow guiding nut 10. safe plug screw 12. of valve body 11. safe pressure ring 13. rupture disk 14. anaerobic type thread locking agent.
Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.
The gas extinguishing system vessel valve of interruptible price start and stop as shown in Figure 1-2, comprise valve body 10, piston rod 6 is set in valve body 10, the top of piston rod 6 arranges spring 5 and piston 4, the top of valve body 10 arranges suction port, suction port connecting valve intracoelomic cavity, suction port place arranges safe pressure ring 12 and safe plug screw 11, and the bottom of safe pressure ring 12 arranges rupture disk 13.The upper end of valve body 10 is nested with pressure cap 1, and pressure cap 1 arranges O RunddichtringO 2 with the joint of valve body 10.The bottom of piston rod 6 sets gradually trim ring 7, seal ring 8 and flow guiding nut 9.Between the inner side of valve body 10 and piston 4, seal ring 3 is set.The upper end of piston rod 6 arranges anaerobic type thread locking agent 14.
First install primer liner, start primer liner, startup gas breaks up rupture disk makes startup gas by vessel valve top, and then the downward extrusion spring of gas, makes piston rod downward.The agent of vessel valve internal firefighting is normally flowed out from extinguishing agent outlet.Close primer liner, container internal pressure impels extinguishing agent upwards to flow, and drives piston rod to move upward, and moving to summit extinguishing agent cannot flow out from extinguishing agent outlet, thus reaches the object of sustainable control extinguishing agent switch.
Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
