Abstract
The utility model relates to the gas extinguishing system vessel valve of band pressure-reducing function.On current vessel valve inside, accent adopts seal washer sealing, causes unadjustable rate of discharge, cannot reach effect of easing stress.The utility model comprises 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 threeway suction tude, suction tude top arranges two suction ports, suction tude bottom connecting valve intracoelomic cavity, and suction port place arranges safe pressure ring and safe plug screw, the bottom of safe pressure ring arranges rupture disk, and the upper end of described piston rod arranges the agent of anaerobic type thread locking.The utility model improves vessel valve part-structure in the market, and vessel valve just effectively can adjust mouth pressure in bottle group, without the need to regulating bottle group pressure by system decompression device.Save cost, and decrease the complicated procedures of forming of pressure regulation.
Description
Technical field
The utility model relates to the gas extinguishing system vessel valve of band pressure-reducing function.
Background technique
On current vessel valve inside, accent adopts seal washer sealing, causes unadjustable rate of discharge, cannot reach effect of easing stress.And usually need to install decompressor additional to regulate bottle group pressure, pressure regulation needs, through sequence of operations, to bring inconvenience, and cost is also higher.
Model utility content
The utility model, for the problems referred to above, provides a kind of gas extinguishing system vessel valve with pressure-reducing function, adopts piston type to fluctuate and controls the extinguishing agent flow of extinguishing agent outlet, make unadjustable rate of discharge in the past become regulating flow quantity, reach effect of easing stress.
For this reason, the utility model takes following technological scheme, with the gas extinguishing system vessel valve of pressure-reducing function, 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 threeway suction tude, suction tude top arranges two suction ports, suction tude bottom 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, and the upper end of described piston rod arranges the agent of anaerobic type thread locking.
The sidepiece of valve body arranges outlet, and outlet port arranges safety helmet, arranges red copper pad and circlip in safety helmet.
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 under the prerequisite of normal work guaranteeing device security and system, and improve vessel valve part-structure in the market, vessel valve just effectively can adjust mouth pressure in bottle group, without the need to regulating bottle group pressure by system decompression device.Save cost, and decrease the complicated procedures of forming of pressure regulation.
When inlet charge, rupture disk explosion, the downward extrusion spring of upper accent inner space gas, piston rod is driven to open vessel valve, the extinguishing agent of vessel valve inside withstands piston rod again when flowing out, starting gas pressure by regulating, adjusting fluctuating of piston rod and reducing the flow of extinguishing agent outlet, thus reaching effect of easing stress.
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, 15. red copper pad 16. circlip 17. safety helmets.
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, and the sidepiece of valve body 10 arranges outlet, and outlet port arranges safety helmet 17, arranges red copper pad 15 and circlip 16 in safety helmet 17.
First install primer liner, start primer liner, startup gas breaks up rupture disk makes startup gas by vessel valve top, and then gas enters the downward extrusion spring of accent, makes piston rod downward, opens vessel valve.Extinguishing agent upwards pushes up piston rod again while flowing out, and by regulating the pressure piston bar starting gas to fluctuate, thus arriving control extinguishing agent flow, arriving effect of easing stress.
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.
