Description

Fire-extinguishing apparatus and fire-extinguishing apparatus valve
Contain in the present invention relates to have gaseous pressure mediums the firing-fighting medium jar fire-extinguishing apparatus and as the fusible hollow body of the element of triping, this fusible hollow body is pressurizeed by the gaseous pressure mediums in the firing-fighting medium jar.The present invention relates to the fire-extinguishing apparatus valve that is used for this class fire-extinguishing apparatus equally.
Applicant is sold a kind of fire-extinguishing apparatus with " Fire Trace  System " name, and it can be just in case just can trip-free without outside energy when catching fire." Fire Trace  System " comprises basically at least: a firing-fighting medium jar, and interior Sheng is as the gaseous pressure mediums of propellant or fire smothering gas; And special hose, it is communicated with the firing-fighting medium jar, and is pressurizeed by the gaseous pressure mediums in the fire suppression bottle.Special hose is installed in above the position with the hidden danger of catching fire under pressure.It comprises special exploitation, and is age inhibiting, and the polymer of antiseep and design are for example broken fire hose tube wall between 100 ℃ to 11O ℃ temperature and the gaseous pressure mediums ease is put.
Two kinds of " Fire Trace  System " variants are arranged.Hose is directly connected on the firing-fighting medium jar in first kind of variant.Hose breaks when contingency is caught fire, and firing-fighting medium flows to breakdown point through hose always and here discharges.Therefore hose is not only as triping element but also as the conveyer line of firing-fighting medium.In second kind of variant, hose is connected on the firing-fighting medium jar by control valve.In case when pressure descended in the relative firing-fighting medium jar of the pressure in the hose, control valve was opened, and contained object in the firing-fighting medium jar is discharged.Produce pressure and fall in hose, hose can break at any one under the effect in heat when contingency is caught fire.Be equipped with this variant just in case when catching fire several firing-fighting medium jars can act on simultaneously, so for example in a closed space, can realize certain density gas fire-extinguishing medium without difficulty.
Above-mentioned control valve comprises valve seat, is placed in the chamber of triping that diaphragm type closure member on the valve seat and closure member form the pressure area therein.By the closure member connecting hole chamber of triping under pressure is communicated with the firing-fighting medium jar.Closure member is design like this and arrange together with its pressure area, promptly presses to valve seat when the firing-fighting medium jar equates with the chamber pressure of triping, and lifts off a seat when mentioning during drop of pressure in the chamber of triping.Drop of pressure is owing to be directly connected to hose in the chamber of triping and break and cause in the chamber of triping.
Up to the present, " Fire Trace  System " definitely successfully used fire fighting powder, water, and AFFF foam or new halogen exchange gas, still the operating principle of " Fire Trace  System " is not suitable for adopting CO 2As firing-fighting medium.Because at CO 2Gas pressure and temperature are closely related in the firing-fighting medium jar, and when ambient temperature fluctuateed, trip temperature just unacceptable variation may take place.This variation of trip temperature is definitely disadvantageous, because trip temperature descends when ambient temperature is high, and it increases when ambient temperature is low.
The present invention is just based on such task, make that the trip temperature of this pattern fire-extinguishing apparatus introduced above is irrelevant with the variation of ambient temperature out and away.
This problem is to solve like this according to the present invention, has settled pressure controller between firing-fighting medium jar and fusible hollow body.Pressure controller has reduced the pressure in fusible hollow body and has weakened in the firing-fighting medium jar pressure oscillation to the effect of fusible hollow body pressure.So just make and to have nothing to do with the variations in temperature that causes pressure oscillation in the firing-fighting medium jar out and away by the meltdown property of fusible hollow body and the trip temperature of hollow body internal pressure decision.Even thereby according to the present invention when the ambient temperature significant change fire-extinguishing apparatus also can adopt CO 2Move as firing-fighting medium.
In addition, pressure controller also has following advantage according to the present invention:
Pressure in the fusible hollow body can irrespectively be adjusted with the gas pressure in the firing-fighting medium jar, makes a same fusible hollow body can be used for all various firing-fighting mediums and all stuffing pressures and still realizes same trip temperature;
Internal pressure in the fusible hollow body can be adjusted by pressure controller and with the suitable trip temperature of condition of living at an easy rate.In order to prevent the mistrip under external high temperature, can adjust to high trip temperature by pressure controller.
Because fusible hollow body under low pressure works, fusible hollow body faces low stress, so it aging just slower and can keep long-time running.
Fusible hollow body generally is exactly fusible hose, and its free end sealing also is installed in the top, position with the fiery hidden danger of catching fire.If but fusible hollow body for example is designed to little tubular, the tubulose network of rigidity or large-area air cushion do not exceed scope of the present invention yet.Unique key factor be under a certain specific internal pressure when a certain specified temp (for example 100 ℃) fusible hollow body break and pressed gas overflowed.Certain fusible hollow body must also be enough anti-aging and antiseep.
Because the increased pressure that gas is heated or the pressure controller error causes in the hollow body for example, fusible hollow body preferably should connect an excess pressure valve in order to prevent in fusible hollow body.
Firing-fighting medium can be fire fighting powder or extinguishing fluid, and pressure medium can be propellant gas, for example nitrogen.But firing-fighting medium also can be a fire smothering gas.Great advantage of the present invention is that available carbon dioxide is as firing-fighting medium.Should be noted that and to form CO very simple, trip-free like this 2Fire-extinguishing apparatus, it does not need to electrically contact, and does not need outside energy to move fully, and seldom maintenance is insensitive and still can the height reliability service in extreme external condition to mistake.The CO of this trip-free 2Fire-extinguishing apparatus can perform well in for example switch gear, and machine room in the protection of motor and urgent TRT, then often can run in the variation of these local ambient temperatures between-20 ℃ to+60 ℃.
The direct connection with the firing-fighting medium jar of pressure controller do not exceeded scope of the present invention yet.The firing-fighting medium jar will emptying after by the hollow body that breaks through pressure controller.But be preferably between pressure controller and the firing-fighting medium jar control valve is installed.The control valve of this pattern preferably includes valve seat, is installed in the closure member on the valve seat, is formed the chamber of triping of pressure area therein by closure member, and the jockey that is connected with the firing-fighting medium container of the chamber of will triping under pressure.Closure member with pressure area is like this design and arrange, the firing-fighting medium jar with trip that it pressed to valve seat when pressure equated between the chamber, and when it is mentioned from valve seat during pressure decline in the chamber of triping.Fusible hollow body is connected with the chamber of triping through pressure controller under pressure, makes the drop of pressure that causes immediately in the chamber of triping of sewing in the fusible hollow body that causes when catching fire, and result's gas pressure in the firing-fighting medium jar makes closure member mention from valve seat.The control valve of this pattern preferably should have the exit opening that a firing-fighting medium is used at least.When closure member when valve seat is mentioned, firing-fighting medium can be discharged by exit opening through valve seat from control valve.
In a preferred examples of fire-extinguishing apparatus, at least one exit opening terminal of control valve is in fusible hollow body, as the conveyer line of firing-fighting medium.Control valve conveyer line by closure is pressurizeed by the gaseous pressure mediums of passing through pressure controller from the firing-fighting medium jar.In case when catching fire, the conveyer line above fire location breaks.Control valve is triped by the drop of pressure in the conveyer line.Firing-fighting medium flows into conveyer line and discharges by the breakdown point above fire location.
Recommend a kind of fire-extinguishing apparatus valve that is applicable to fire-extinguishing apparatus simultaneously according to the present invention.By this fire-extinguishing apparatus valve, any portable or portable CO 2Fire-extinguishing apparatus for example may be used to the trip-free fire-extinguishing apparatus, and does not need external energy to connect.
The fire-extinguishing apparatus valve of this recommendation preferably includes valve body and valve gap, and pressure controller is installed in the valve gap.Locking device can be locked pressure controller when closing position, so just can prevent the emptying of fire-extinguishing apparatus when removing fusible hollow body.
Pressure controller preferably has the spring element that gives stress, by this giving stress and can form pressure in triping of fire-extinguishing apparatus valve connects by spring element.So just can set the pressure of triping in connecting, thereby set trip temperature by the stress that gives that changes spring element.
Introduce one exemplary embodiment by accompanying drawing below according to fire-extinguishing apparatus of the present invention and fire-extinguishing apparatus valve, wherein:
