Description
Technical field
The utility model belongs to fire prevention and uses field, is specifically related to a kind of intelligent container value for fire fighting gas fire extinguishing system equipment.
Background technology
Country is through the reform and opening-up development of 30 years, grow with each passing hour according to the new material of continuous appearance, new technology, fire-fighting domain, invent a lot of fire products, fire fighting gas fire extinguishing system equipment is most popular fire-fighting equipment instantly, and container value is a most important accessory in this kind of equipment.Container value on existing market mostly adopts laterally opened, and laterally opened container value spool has and the aperture of air cavity UNICOM, will cause so laterally opened container value leakage point many, no matter be all-in-one-piece container value structure, or, all there is the problem of sealing leak in the container value structure of separate assembling.Because container value is the stop valve belonging in valve class, sealing means mostly adopts mechanical pressurization device, and this kind of mode is changeless, under high pressure conditions, lacks from main regulation and compensation ability.Like this in external environment condition as temperature, when air pressure etc. change, because mechanically-sealing apparatus is subject to long-term compression shock, and produce sealing leak.Thereby cause medicament to leak.Because fire-fighting domain is a special field, only, in the time that fire occurs, just can work, in fact, how how Leakage prevention, find to leak, and at present domesticly also just adopts weighing device, or pressure display unit etc. regularly detects.And domestic existing measurement mechanism precision does not all also reach requirement.Domestic container value mostly adopts the additional nitrogen cylinder type of drive of magnetic valve in Starting mode at present.This Starting mode is subject to capacity limit, spatial limitation, and can increase a lot of costs.
Summary of the invention
The purpose of this utility model is to provide a kind of intelligent container value of novel fire fighting gas fire extinguishing system equipment, solve the existing unstable properties of existing fire fighting gas fire extinguishing system container value, complicated structure, there is defect in sealing device, take up room larger, the more high defect of cost.
This practical technical solution is by such realization:
For an intelligent container value for fire fighting gas fire extinguishing system equipment, it comprises upper valve body, valve base, lower valve body, controller, high-precision pressure sensor, is connected with audible-visual annunciator on controller; Valve base top and upper valve body form upper gas chamber, and upper gas chamber is divided into upper chamber and lower chamber by piston by upper gas chamber;
Lower air chamber is formed at valve base bottom, and air cavity bottom connects with steel cylinder source of the gas by lower valve body, and lower air chamber side has an air-out apparatus;
There is seal receptacle valve rod assembly lower end, and the piston area of valve rod assembly upper end assembling is greater than the area of valve rod assembly seal receptacle; Valve rod assembly connects in aggregates with piston.
Air pipe is communicated with upper gas chamber with steel cylinder source of the gas, air pipe is controlled by starting and vacuumizing two-in-one device.
In the time that container value is in running order, controller starts and vacuumizes two-in-one device and extract the gas holding in agent bottle and be transported to upper chamber by tracheae, use principle of differential pressure to back down valve rod assembly, open container value lower air chamber and hold agent handling system with this, medicament is flowed out in agent bottle calmly, and then from the air-out apparatus of container value, spray again, to reach the object of fire extinguishing.
Container value lower air chamber side has a little air chamber, and stingy indoor location has high-precision pressure sensor contact.
When container value is during in off position, controller is by starting and vacuumizing two-in-one device vacuum pumping state; Leak when the sealing device place of container value, vacuum environment is destroyed; In the time that leakage air pressure reaches 0.05MPa, survey contact by the high-precision pressure in high-precision pressure sensing device and carry out sound and light signal alarm equipment alarm, reach the object of monitoring.And start with vacuumizing two-in-one device and regulate free type air spring regulating valve stem assembly to reseal by controller, and again lower chamber is evacuated.
The utility model that adopts said structure is installed on the appearance agent bottle that medicament is housed, this structure starts working, valve rod assembly lower end seal receptacle is automatically upwards tight with the opening sealing of holding agent bottle by the lower air chamber of valve base in the interior pressure effect of holding agent bottle, what free type air spring was complementary holds out against, at the automatic regulating seal property energy along with the variation of external environment.Therefore can seal medicament completely in appearance agent bottle.Air pipe, by connecting upper gas chamber and flask for medicinal preparations group, reaches automatic Starting mode, does not need other source of the gas, provides cost savings and space.Separately increased high-precision pressure sensor, by audible-visual annunciator transmission of signal to controller, automatic detection sealing leak, precision reaches 0.05MPa, automatically regulates seal receptacle.Thereby greatly improve security performance.
The utlity model has following advantage:
1, this container value has adopted high-precision pressure sensor, and precision reaches 0.05MPa, in the same industry, still uses for the first time at home, only has abroad Italy and the U.S. to have this application.
2, this container value has adopted and has started and vacuumize two-in-one device, uses differential pressure principle, has reached and has vacuumized and autostart function with air pipe UNICOM;
3, this container value has adopted automatic adjusting sealing device, can automatically regulate according to the variation of external environment; Reach hermetic effect, made medicament loss drop to minimum.
4, this container value reaches automatic alarm by controller, automatically starts, and automatic vacuum, can reach automation object completely, this product is had and have in the world certain competitiveness.
