Detailed description of the invention
In this utility model cited " on ", the term such as D score, it is merely convenient to understanding of narration, and is not used to limit the enforceable scope of this utility model, being altered or modified of its relativeness, changing under technology contents without essence, when being also considered as the enforceable category of this utility model.
As depicted in figs. 1 and 2, a kind of spy fire tube temperature-sensitive self-starting extinguishing device container value, mainly include valve body 3, bonnet 2, small ball 1, piston 6, stage clip 5, aperture screw 4, pressure switch joint 7, safety relief device 8, pressure meter switch joint 9；Small ball 1 lower end is connected to bonnet 2 upper end, and bonnet 2 is arranged on valve body 3 upper end；Bonnet 2 is provided with axially extending bore, and by small ball 1 inner chamber and valve body 3 inner space, small ball 1 upper end is provided with outlet C, is used for connecting spy fire tube, and its effect is the flow direction controlling extinguishing chemical；
Described valve body 3 is the cylinder of the hollow cavity with up/down perforation, and the sidewall of valve body 3 offers outlet B, and lower end is provided with import A；Circumferentially spaced on the sidewall of valve body 3 pressure switch joint 7, safety relief device 8, pressure meter switch joint 9 are installed；
The inner chamber of described valve body 3 is provided with piston 6, piston 6 and valve body 3 coaxial line, and the outside dimension of described piston 6 is suitable with the internal diameter size of described valve body 3；The axially extending bore of band counterbore it is provided with in piston 6, piston 6 upper end area is more than lower end area, stage clip 5 is arranged between the counterbore of bonnet 2 bottom and piston 6 upper end, piston 6 lower end is provided with aperture screw 4, described aperture screw 4 is provided with axially extending bore, this through hole is shoulder hole, and the diameter of upper hole, more than the diameter of bottom hole, is installed with steel wire in lower through-hole.
Visiting fire tube extinguishing device container value is differential structure; its effect is under the effect of identical pressure P; by controlling the difference in areas at the upper and lower two ends of piston, make piston upper end directed force F 1 more than lower end directed force F 2, it is ensured that piston moves downward the outlet B sealed up on valve body under the effect of pressure P.When the pressure release of piston upper end, piston moves upward under the effect of cavity of resorption pressure P, and the outlet B on valve body opens, and discharges extinguishing chemical.
The epicoele of described piston 6 and cavity of resorption, the axially extending bore in piston 6 and the axially extending bore in aperture screw 4 communicate.
Described pressure switch joint 7 is valve core structure, is used for connecting pressure switch, and feedback visits fire tube temperature-sensitive self-starting extinguishing device actuating signal.
The effect of aperture screw 4 is the flow controlling extinguishing chemical.The a diameter of 1mm of aperture screw 4 lower through-hole, in hole, worn steel wire diameter is 0.7mm.Before valve assembles, by the bending of stainless steel silk one end, the other end passes bending again after aperture, and after so assembling, steel wire is limited in hole.
The Main Function of stage clip 5 is that damping and extinguishing chemical spray return piston 6 after pressure release when valve opening.
The effect visiting fire tube temperature-sensitive self-starting extinguishing device container value is to seal and release extinguishing chemical.
Visit fire tube temperature-sensitive self-starting extinguishing device container value to be arranged on spy fire tube extinguishing device container, pressure meter switch joint 9 in container, fill extinguishing chemical and gas-pressurized.Visit fire tube temperature-sensitive self-starting extinguishing device container value at ordinary times in container under the effect of extinguishing chemical and gas-pressurized pressure P; difference in areas due to piston about 6 two ends; make piston 6 upper end directed force F 1 more than lower end directed force F 2; guarantee that piston 6 moves downward the outlet B sealed up on valve body 3 under the effect of pressure P; make valve be closed, seal up extinguishing chemical.
When a fire, the small ball 1 visited on fire tube temperature-sensitive self-starting extinguishing device container value exports the spy fire tube temperature-sensitive explosion that C is connect, the extinguishing chemical of piston 6 upper end discharges by visiting explosion mouth on fire tube through small ball 1, due to the aperture metering function on the aperture screw 4 that piston 6 lower end connects, make the extinguishing chemical flow flowing to visit fire tube through piston 6 minimum, the pressure P rapid decrease of piston 6 upper end, piston overcomes the overbottom pressure of piston upper end and the active force of stage clip 5 to move upward under the effect of lower end pressure P, on valve body 3, interface B opens, extinguishing chemical in container is flowed to guard plot by valve body 3 import A through the discharge conduit that outlet B is connect and implements fire extinguishing.Meanwhile, the pressure switch that pressure switch joint 7 connects, spy fire tube temperature-sensitive self-starting extinguishing device actuating signal is fed back to warning device or Central Control Room.Noting, small ball 1 should be closed before connection spy fire tube all the time, visits fire tube connecting and confirms that managing interior charge pressure is not less than in spy fire tube temperature-sensitive self-starting extinguishing device container value after pressure, and slow unlatching small ball 1 also guarantees that it is in opening all the time.
Should be appreciated that above is illustrative and not restrictive by preferred embodiment to the detailed description that the technical solution of the utility model is carried out.Technical scheme described in embodiment can be modified on the basis of reading this utility model description by those of ordinary skill in the art, or wherein portion of techniques feature is carried out equivalent, and these amendments or replacement, the essence not making appropriate technical solution departs from the spirit and scope of this utility model embodiment technical scheme, must be contained by claim of the present utility model.
