The course of work of the low temperature extinguisher valve door of the present embodiment is with reference to embodiment, and its difference is as follows：
Although the sealing knot when low temperature extinguisher valve door is closed, between valve rod lower seal and taper valve opening
Structure determines the leakage problem of low temperature extinguisher valve door, the sealing structure of upper sealing ring to extinguisher valve leakage problem not
Produce impact；But during fire extinguisher use（Valve rod lower seal is separated with the inner conical surface of taper valve opening）, seal on valve rod
The reliability of the sealing structure formed between circle and upper valve opening, then directly affect normally using for fire extinguisher.Conventional fire extinguisher exists
During use, especially used in low temperature environment during sealing structure because between sealing ring and upper valve opening occurs
It is unstable, and occur leakage between upper sealing ring and upper valve opening, affect the normal problem for using of fire extinguisher；The present embodiment pin
This problem is improved, effectively solving this problem is further ensured that normally using for fire extinguisher.
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
Till 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, the main channel and fire extinguisher inner chamber on valve rod between sealing ring and valve rod lower seal
It is 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, till being resisted against on taper connection hole；In this process
The annular inflatable intracavity of sealing ring on the gas press-in valve rod in outer radial hole is made sealing ring expansion on valve rod by piston body, from
And ensure valve rod between sealing ring and upper valve opening formed sealing structure reliability, 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, affect 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 resets, 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, the annular inflatable chamber of sealing ring on valve rod is made 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 low temperature extinguisher valve door is closed again.
