For the course of work of the low temperature extinguisher valve door of the present embodiment with reference to embodiment, difference is as follows：
Although close between valve rod lower seal and taper valve opening when low temperature extinguisher valve door is closed
Seal structure determines that the leakage problem of low temperature extinguisher valve door, the sealing structure of upper sealing ring ask extinguisher valve leakage
Topic does not have an impact；But during fire extinguisher use（Valve rod lower seal is detached with the inner conical surface of taper valve opening）, on valve rod
The reliability of the sealing structure formed between sealing ring and upper valve opening then directly affects the normal use of fire extinguisher.Tradition fire extinguishing
Device in use, will appear during use because of the sealing between upper sealing ring and upper valve opening especially in low temperature environment
Structural instability, and the problem of leaked between upper sealing ring and upper valve opening, influence the normal use of fire extinguisher；This implementation
Example is improved for this problem, is effectively solved the problems, such as this, is further ensured that the normal use of fire extinguisher.
When fire extinguisher uses process, operator presses down handle.During handle presses down, handle elder generation and valve
The upper-end contact of loop bar presses down valve pocket bar；Then, handle presses down valve rod again with the upper-end contact of valve rod, until valve
Until bar limited block is resisted against on the upper surface of valve body, at this point, valve rod lower seal is detached with the inner conical surface of taper valve opening, open
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 on valve pocket bar
Between two interfaces are located at, to which first interface and second interface be cut off.
Opening extinguisher valve behind the door, the main channel on valve rod between sealing ring and valve rod lower seal and fire extinguisher inner cavity
It is connected（Main channel on valve rod between sealing ring and valve rod lower seal is identical as the pressure in fire extinguisher, is in high pressure shape
State）, piston body will move inside under ambient pressure effect, until being resisted against on taper connection hole；In this process
The annular inflatable intracavitary of sealing ring on gas indentation valve rod in outer radial hole is made sealing ring on valve rod expand by piston body, from
And ensure the reliability of the sealing structure formed between sealing ring and upper valve opening on valve rod, avoid because upper sealing ring and upper valve opening it
Between sealing structure it is unstable, and leaked between upper sealing ring and upper valve opening, influence asking for the normal use of fire extinguisher
Topic.
When fire extinguisher is stopped using, operator discharges handle, and at this time under the action of third resetting spring, valve pocket bar will
Reset is moved up, i.e., valve pocket bar lower position block is resisted against on the lower face of vertical valve pocket, at this point, first interface is located at second interface
On valve pocket bar between sealing ring and valve pocket bar lower seal, the annular inflatable chamber of sealing ring on valve rod is made to pass through main channel, connection
Hose, second interface and first interface are in communication with the outside, to make sealing ring on valve rod shrink.When sealing ring is shunk on valve rod
Afterwards, under the action of (the first back-moving spring, valve rod will be jacked up up, and valve rod lower seal and the inner conical surface of taper valve opening is made to abut
It is connected, valve outlet is cut off with valve body import, and low temperature extinguisher valve door is closed again.
