When valve rod lower seal is abutted with the inner conical surface of taper valve opening to be connected, valve outlet is cut off with valve body import.
When valve rod moves down along sprue and valve rod lower seal is separated with the inner conical surface of taper valve opening, valve body goes out
Mouth is connected with valve body import.
The use process of the dry powder extinguisher structure of the present embodiment is as follows：
First, will remove on bayonet socket of the hard main jet pipe by anchor ear, then, as shown in figure 1, by the way that hard main jet pipe will be connected
Flexible pipe is stretched, and makes connection flexible pipe be generally in same straight line with hard main jet pipe, now, in the presence of compression spring, hard
The conduit that is slidably connected will be moved toward hard connecting tube direction, until hard is slidably connected, conduit is resisted against on connecting tube limited block
Till, so as to hard main jet pipe and hard connecting tube are connected into a hard jet pipe by the hard conduit that is slidably connected.
Second, safety plug is extracted, then, because the hard conduit that is slidably connected connects hard main jet pipe and hard connecting tube
A hard jet pipe is connected into, thus the jet pipe of fire extinguisher can be held in fire-extinguishing operations, operator is only needed on the other hand
Or both hands hold carrying handle and pressure handle, and by under pressure handle can Open valve component, put out a fire, greatly facilitate that operator is actual to be made
With.（Pressure handle moves down valve rod after pushing, so that valve rod lower seal is separated with the inner conical surface of taper valve opening, then valve outlet
Open valve component is connected with valve body import）.
3rd, after the completion of fire extinguisher use, hard can be slidably connected conduit toward the spacing Block direction of jet pipe by operator
It is mobile, expose connection flexible pipe；Then operator by the pipe down bending of hard main jet, and can snap on the bayonet socket of anchor ear, such as
This can facilitate fire extinguisher to deposit.The nozzle component of this programme not only can be realized can be without the need for holding fire extinguishing in fire-extinguishing operations
The jet pipe of device, the function of greatly facilitating operator actually used；And do not interfere with the storage of fire extinguisher.
On the other hand, when safety plug is plugged between carrying handle and pressure handle, dry powder extinguisher structure is closed；This
When, valve rod up jack-up is made valve rod lower seal abut with the inner conical surface of taper valve opening and is connected by (the first back-moving spring, and valve body goes out
Mouth is cut off with valve body import, and dry powder extinguisher structure is closed.
When dry powder extinguisher structure is closed, the sealing structure between valve rod lower seal and taper valve opening is determined
Determine the leakage problem of dry powder extinguisher structure, and the sealing structure of upper sealing ring does not produce shadow to extinguisher valve leakage problem
Ring.
When dry powder extinguisher structure is closed, due to the internal diameter of taper valve opening it is gradually less from bottom to top, when
(the first back-moving spring makes valve rod lower seal abut with the inner conical surface of taper valve opening when being connected, and valve rod lower seal is by pressurized receipts
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 stably, 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 asking for extinguisher valve leakage can be occurred used in low temperature environment with the current low temperature extinguisher valve of effectively solving

The course of work of the dry powder extinguisher structure of the present embodiment is with reference to embodiment, and its difference is as follows：
Although when dry powder extinguisher structure is closed, the sealing structure between valve rod lower seal and taper valve opening is determined
The leakage problem of dry powder extinguisher structure is determined, the sealing structure of upper sealing ring does not produce shadow to extinguisher valve leakage problem
Ring；But during fire extinguisher use（Valve rod lower seal is separated with the inner conical surface of taper valve opening）, on valve rod sealing ring with it is upper
The reliability of the sealing structure formed between valve opening, then directly affect normally using for fire extinguisher.Conventional fire extinguisher was being used
Cheng Zhong, especially used in low temperature environment during occur that because on the sealing structure between sealing ring and upper valve opening is unstable
It is fixed, and occur leakage between upper sealing ring and upper valve opening, affect the normal problem for using of fire extinguisher；The present embodiment is directed to this
One 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
Piston body makes sealing ring expansion 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 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 dry powder extinguisher structure is closed again.
