Contracting, forms larger contact area and the inner conical surface of taper valve opening between, makes to be formed between valve rod lower seal and taper valve opening
More stablize, reliable sealing structure；And valve rod lower seal is more up moved, then between valve rod lower seal and taper valve opening
Extruding force it is bigger, the contact area between the inner conical surface of valve rod lower seal and taper valve opening is bigger, and sealing structure is more reliable；
Thus can effectively solve current low temperature extinguisher valve in low temperature environment using occur extinguisher valve leak ask
Topic.
When in use, first, safety plug is extracted, then, it is only necessary to press down valve rod（Will pressure handle push, you can
Valve rod is pressed down）, valve rod lower seal is separated with the inner conical surface of taper valve opening, then valve outlet is connected with valve body import,
That is cocoa Open valve, its is easy to use.
On the other hand, when fire extinguisher needs ftercompction, operator can be by ftercompction hole to ftercompction in fire extinguisher.In ftercompction
During, when the air pressure in fire extinguisher bottle body exceedes setting value, safe releasing device automatically turns on pressure release；When pressure pressure release is arrived
When in normal range (NR), then it is automatically switched off.
