Description
Technical field
The utility model relates to valve fields, and in particular to heptafluoro-propane bottle valve.
Background technique
Heptafluoro-propane be it is a kind of acted on inhibition based on, have both the clean coal power system of physics fire extinguishing effect, contain
Container (such as: the bottle body) gas outlet for filling heptafluoro-propane is equipped with heptafluoro-propane bottle valve.The Septenary-fluorine propane container valve one of the prior art
As the extinction using gas cylinder valve that opens and closes realized using principle of differential pressure, by valve body, piston component, valve deck, release pressure cap and metal film
The composition such as piece, piston are equipped with duct, penetrate through air inlet and air storing cavity.In use, heptafluoro-propane bottle valve is installed on splendid attire
On the bottle body of heptafluoro-propane, then by the air charging system on valve to pneumatic inflation, since piston is in air storing cavity side compression face
Product is bigger than air inlet side, and two sides form pressure difference to piston up and down, covers piston upper seal closely on knife-edge sealing surface, valve
It closes.When fire occurs in environment, under the action of air-operated pilot valve or solenoid valve, by top lancination broken release pressure cap and valve deck
Between metallic membrane, compressed gas is released in air storing cavity, and pressure is die-offed, and side pressure good general in piston intake hole is greater than air storing cavity side pressure
By force, piston is lifted off sealing surface, and valve is opened, and the intracorporal heptafluoro-propane gas of bottle can come out from venthole at this time, externally
The fire extinguishing of portion's environment.
But in fire extinguishing procedure, since metallic membrane is punctured, air inlet by hole link air storing cavity, and due to
Air pressure is larger in bottle, and there will be small part heptafluoro-propanes to let out from duct, causes certain waste.In addition, existing
The typically no safety device of heptafluoro-propane bottle valve, there are some potential safety problemss.
Therefore, how existing heptafluoro-propane bottle valve is improved, overcomes the problems, such as it above-mentioned, is ability
A field technique personnel problem urgently to be resolved.
