Embodiment
As shown in Figure 1 to Figure 3, the vessel valve of 1301 extinguishing agent storage bottles comprises bonnet assemblies 1, mangetic core assembly 2, valve body 3, plug 4, relief valve assembly 5, pressure gauge 7, wherein mangetic core assembly 2 fits into the endoporus of valve body 3 by the sealing of O RunddichtringO, bonnet assemblies 1 is connected with valve body 3 thread seals by O RunddichtringO, plug 4 is screwed onto on the side opening of valve body 3, relief valve assembly 5 is screwed onto on valve body 3, on the valve body 3 on relief valve assembly 5 opposites, have a pressure tap a, pressure gauge 7 is arranged in this pressure tap a.On valve body 3, horizontal symmetrical is provided with attachment hole b, b ' respectively, and the horizontal sextant angle of the first attachment hole b and relief valve assembly 5 is 90 °.The first attachment hole b is comprised of the hole of coaxial different-diameter, the first attachment hole b is not communicated with the endoporus of this valve body 3, the internal thread in the first attachment hole b outside is tightly connected mutually with the outside thread of secondary seal plug 10, and the position clamping mutually with the first attachment hole b on secondary seal plug 10 is provided with O-ring seals 9.The upper end of the valve pars intramuralis that the first attachment hole b is arranged on valve body 3 near the smaller side in valve wall internal surface aperture with one and the cylindrical delivery passage f parallel with the axis of this valve body 3 is connected, the lower end perforate of transfer passage f is in valve body bottom surface 15, and transfer passage f is near the outer surface of valve wall.A side near valve wall internal surface in the first attachment hole b is provided with the nonreturn valve core 8 that there are 6 opening d at an edge, the tail end of nonreturn valve core 8 is conical surface e, the angle beta of conical surface e is 80 °, the outer surface of nonreturn valve core 8 is provided with outside thread, the first attachment hole b internal surface upper and nonreturn valve core 8 corresponding positions is provided with the internal thread that the outside thread with nonreturn valve core 8 matches, while inwardly tightening nonreturn valve core 8, the conical surface e of nonreturn valve core 8 and the corresponding internal surface of the first attachment hole b are sealed and matched, and close transfer passage f.When quasi-operating status, nonreturn valve core 8 is screwed into valve body 3 and is realized with it hard sealing by screw thread, and secondary seal plug 10, by being screwed on valve body 3, is realized secondary seal by O-ring seals 9 therebetween, thereby can guarantee its sealability.
The structure of the second attachment hole b ' is similar to the first attachment hole b, but the second attachment hole b ' is connected with the endoporus of this valve body 3, the internal thread in second attachment hole b ' outside is tightly connected mutually with the outside thread of secondary seal plug 17, and the position clamping mutually with the second attachment hole b ' on secondary seal plug 17 is provided with O-ring seals 18.Structure, the shape of the nonreturn valve core 16 in the second attachment hole b ' are identical with nonreturn valve core 8, and while inwardly tightening nonreturn valve core 16, the corresponding internal surface of the conical surface e of nonreturn valve core 16 and the second attachment hole b ' is sealed and matched, and closes the second attachment hole b '.
Generally, the quantity n of the opening d of nonreturn valve core 8,16 is 2≤n≤8; The angle beta of the conical surface e of nonreturn valve core 8,16 is 30 °≤β≤150, and it all can realize the function of hard sealing within the scope of this.
A leakproof screw 6 is housed in pressure tap a, and the internal thread of the outside thread of leakproof screw 6 and this pressure tap a corresponding position forms Spielpassung.When pressure gauge 7 damages need dismounting and change, due to the existence of leakproof screw 6, make after disassembling pressure gauge 7, to there will not be leakage of medicament phenomenon, a large amount of medicaments avoids waste.
As Fig. 4 medicament pours in down a chimney as shown in schematic diagram, when 1301 medicaments pour in down a chimney, secondary seal plug 10,17 is pulled down, unscrew nonreturn valve core 8,16, then change into and pour in down a chimney special joint, and connect medicament and pour in down a chimney pipeline g and gas-liquid equilibrium pipeline h, by Fig. 4, place and pour in down a chimney bottle 14 and returnable bottle 13, opening liquid phase valve 12,1301 medicaments flows in returnable bottle 13 from pouring in down a chimney bottle 14 continuously.When medicament flow velocity stops or is very slow, open gas valve 11, make two pressure of the inside of a bottle reach balance---medicament continues to flow into returnable bottle 13 by Action of Gravity Field, until reclaim completely.1301 extinguishing agents are Trifluoromonobromomethane, and molecular formula is CF
3br, this extinguishing agent is water white transparency shape liquid.
It should be noted that; embodiment is only to the explanation of technical solution of the present invention and explanation; should not be understood as the restriction to technical solution of the present invention, any employing essence summary of the invention of the present invention and only do local change, must fall within the scope of protection of the present invention.
