Abstract
A kind of fire extinguisher is the utility model is related to automatically reset container valve arrangement.At present, puncture the structure of diaphragm spurted every time and then it is secondary fill extinguishing chemical before need to change the diaphragm being punctured.It is relatively complicated, it is necessary to waste substantial amounts of manpower, time etc. to change diaphragm process.The utility model includes valve element, epicoele and cavity of resorption are formed in valve element, difference in areas be present in valve element epicoele and cavity of resorption, valve element is pressed downward close front cover, it is characterized in that the epicoele of the valve element sets valve inside, described valve inside arrangement reset spring, the top of the valve inside sets push rod, described push rod is driven by drive mechanism and moved up and down, and the beneficial effects of the utility model are：The opening ways of existing container value are improved, the epicoele of valve element is by the original pattern for puncturing diaphragm structure and being changed to valve inside, opening ways from original pricker puncture diaphragm release epicoele gas be changed into thimble push valve inside release gas, after gas discharges, valve inside automatically resets, and eliminates the process changed and puncture diaphragm.Material is more saved in structure, and may be reused.
Description
Technical field
A kind of fire extinguisher is the utility model is related to automatically reset container valve arrangement.
Background technology
At present, the conventional foamite container valve of company is using the structure for puncturing diaphragm, that is to say, that when extinguishing chemical leads to
When crossing container value and filling into container, because the difference in areas of upper and lower chamber is so that container value seals, the sealing of epicoele passes through valve element
Seal membrane mechanism, when thimble punctures the seal membrane of epicoele, upper cavity pressure reduces, and prevents valve element from keeping original sealing shape
State, and then discharge extinguishing chemical.More than this structure for puncturing diaphragm spurted every time and then it is secondary fill extinguishing chemical before need
Change the diaphragm being punctured.It is relatively complicated, it is necessary to waste substantial amounts of manpower, time etc. to change diaphragm process.
Utility model content
The purpose of this utility model is the problem of presence for prior art, there is provided a kind of fire extinguisher automatically resets container value
Structure, the process changed and puncture diaphragm is eliminated, material is more saved in structure, and may be reused.
To reach above-mentioned purpose, the utility model adopts the following technical scheme that：A kind of fire extinguisher automatically resets container value knot
There is difference in areas in structure, including valve element, the interior formation epicoele of valve element and cavity of resorption, valve element epicoele and cavity of resorption, valve element is pressed downward close front cover,
It is characterized in that the epicoele of the valve element sets valve inside, described valve inside arrangement reset spring, the top of the valve inside
Push rod is set, described push rod is driven by drive mechanism and moved up and down,
Described drive mechanism is electromagnet.
The both sides of the container value set steam vent.
The beneficial effects of the utility model are：The opening ways of existing container value are improved, the epicoele of valve element by
The pattern for puncturing diaphragm structure and being changed to valve inside originally, opening ways puncture diaphragm release epicoele gas by original pricker and become
Valve inside is pushed for thimble and discharges gas, and after gas discharges, valve inside automatically resets, and eliminates the work changed and puncture diaphragm
Sequence.Material is more saved in structure, and may be reused.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is close-up schematic view of the present utility model.
Embodiment
With reference to specific implementation case, the utility model is expanded on further.
As depicted in figs. 1 and 2, a kind of fire extinguisher is automatically reset container valve arrangement, including valve element 3, and epicoele is formed in valve element
And cavity of resorption, valve element epicoele and cavity of resorption have difference in areas, valve element is pressed downward close front cover 4, and the epicoele of valve element sets valve inside 6, gas
Door core arrangement reset spring 5, the top of valve inside set push rod 1, and push rod drives up and down motion by electromagnet 7, and the two of container value
Side sets steam vent 2.
The utility model realization fills-release-, and the detailed process refilled is as follows：
After valve body installs, filled, gas extinguishing agent enters bottle, gradually rises the pressure of valve element bottom, portion
Gas is divided to enter valve element epicoele by the hole among valve element, due to the difference in areas of valve element epicoele and cavity of resorption, valve element is pressed downward closely
Front cover, complete final fill.
When extinguishing chemical bottle group prepares to discharge, electromagnet obtains electric promotion thimble and moved downward, and acts on valve inside, valve
Core is opened, and the valve element upper gas for being used to seal before is discharged by steam vent, and valve element upper cavity pressure reduces, and valve element is due under
The pressure in portion is moved upwards, and valve core sealed cover departs from, and extinguishing chemical completes release.
After extinguishing chemical discharges, because pressure reduces, valve element compresses close because the relation of back-moving spring moves downward
Front cover, so as to be reset to the state filled first.So as to ensure that the auto-reset function of valve body.
It the above is only preferred embodiment of the present utility model, be not limited to the utility model, it is noted that for
For those skilled in the art, on the premise of the utility model technical principle is not departed from, if can also make
Dry improvement and modification, these improvement and modification also should be regarded as the scope of protection of the utility model.
