Description
Technical field
The present invention relates to the bottle valve of a kind of real-time display pressure, belong to fire-fighting system equipment technical field.
Background technology
Bottle valve is for sealing up for safekeeping and controlling one of critical piece discharging extinguishing chemical in fire extinguishing system.At present, the existing bottle valve of fire-fighting domain, all it is made up of valve body, spool, explosion-protection equipment, starter, Pressure gauge and table switch, connecting tube joint etc..Some fire-fighting occasion, particularly electric power fire fighting device, require in Daily Round Check, can judge that by directly seeing pressure gauge reading extinguishing agent pressure is the most qualified, and existing bottle valve generally by the pressure meter switch unclamped on bottle valve to read extinguishing agent pressure, or do not set table switch, directly by Pressure gauge by being threadably coupled within bottle valve, although also being able to read in real time the pressure value of extinguishing chemical, but, Pressure gauge can not be overhauled by specified period.
Summary of the invention
It is an object of the present invention to provide the bottle valve of a kind of real-time display pressure, and at any time Pressure gauge can be verified and overhaul, solve problem present in background technology.
The technical scheme is that
A kind of bottle valve of real-time display pressure, comprise starter, valve body, Pressure gauge, gland, spool, spring, explosion-protection equipment, fire-suppression bottle and main valve plug, valve body is provided with extinguishing chemical import and extinguishing chemical outlet, extinguishing chemical import connects with fire-suppression bottle, main valve plug is arranged in valve body, explosion-protection equipment is placed in valve body-side, starter is connected with valve body, gland is arranged on valve body, and Pressure gauge is arranged on gland, and spool is provided with sealing surface, and be arranged in valve body, corresponding with Pressure gauge position, it is provided with spring in spool, spool is provided with air inlet and venthole；When working properly, when Pressure gauge is threaded onto on valve body by the installation of self, by the seal face just-lift-off on the spool in valve body, the extinguishing chemical in fire-suppression bottle is made to enter Pressure gauge, and it being always maintained at normally open, Pressure gauge shows the storage pressure of extinguishing chemical in fire-suppression bottle in real time；When Pressure gauge needs maintenance to unload, spool is moved under the action of the spring, makes the sealing structure on spool close, and is sealed in valve body by extinguishing chemical, and fire-suppression bottle overhauls Pressure gauge under operating pressure.
Described valve core sealed cover is conical seal (contact) face structure.
Described valve core sealed cover is spherical seal surface structure.
Described spool is provided with groove, forms air inlet and venthole.
Between described gland and valve body, between Pressure gauge and gland, it is respectively equipped with seal washer.
Use the present invention, when working properly, when Pressure gauge is threaded onto on valve body by the installation of self, by the seal face just-lift-off on the spool in valve body, making extinguishing chemical in fire-suppression bottle enter Pressure gauge, and be always maintained at normally open, Pressure gauge shows the storage pressure of extinguishing chemical in fire-suppression bottle in real time.When Pressure gauge needs maintenance to unload, spool is moved under the action of the spring, makes the sealing structure on spool close, and is sealed in valve body by extinguishing chemical, it is achieved fire-suppression bottle can overhaul manometric work under operating pressure as required.
The invention has the beneficial effects as follows: extinguishing agent pressure numerical value can be read at any time, it is ensured that reading correctness and promptness, and at any time pressure can be verified and overhaul.
