Problem；The present embodiment is improved for this problem, effectively solves this problem, is further ensured that the normal of fire extinguisher makes
With.
When fire extinguisher uses process, operator presses down pressure handle.During pressure handle is pressed down, pressure handle elder generation and valve
The upper-end contact of loop bar, valve pocket bar is pressed down；Then, pressure handle again with the upper-end contact of valve rod, valve rod is pressed down, until valve
Untill bar limited block is resisted against on the upper surface of valve body, now, valve rod lower seal is separated with the inner conical surface of taper valve opening, is opened
Extinguisher valve.When valve stem spacing block is resisted against on the upper surface of valve body, sealing ring is located at first interface and the on valve pocket bar
Between two interfaces are located at, so as to first interface and second interface be cut off.
Opening extinguisher valve behind the door, main channel and fire extinguisher inner chamber on valve rod between sealing ring and valve rod lower seal
Being connected, (main channel on valve rod between sealing ring and valve rod lower seal is identical with the pressure in fire extinguisher, in high pressure shape
State), piston body will be moved inside under ambient pressure effect, untill being resisted against on taper connection hole；In this process
Piston body expands sealing ring on valve rod by the annular inflatable chamber of sealing ring on the gas press-in valve rod in outer radial hole, from
And ensure on valve rod the reliability of sealing structure formed between sealing ring and upper valve opening, it is to avoid because upper sealing ring and upper valve opening it
Between sealing structure it is unstable, and between upper sealing ring and upper valve opening occur leakage, influence fire extinguisher it is normal use ask
Topic.
When fire extinguisher is stopped using, operator's release pressure handle, now in the presence of the 3rd back-moving spring, valve pocket bar will
Upper shifting is resetted, i.e., valve pocket bar lower position block is resisted against on the lower surface of vertical valve pocket, and now, first interface is located at second interface
On valve pocket bar between sealing ring and valve pocket bar lower seal, make the annular inflatable chamber of sealing ring on valve rod by main channel, connection
Flexible pipe, second interface and first interface are in communication with the outside, so that sealing ring shrinks on valve rod.When sealing ring shrinks on valve rod
Afterwards, in the presence of (the first back-moving spring, valve rod will up jack-up, valve rod lower seal is abutted with the inner conical surface of taper valve opening
It is connected, valve outlet is cut off with valve body import, and the fire extinguisher with injection valve structure is closed again.
