Preferably, described seal arrangement is made up of locking nut, sealing nut and working masks, described locking nut is socketed on sealing nut top, is provided with working masks between described locking nut and sealing nut, and described working masks is corresponding with sealing nut position.
Preferably, described sealing nut is socketed on valve body, is provided with O type circle between described valve body and sealing nut.
Preferably, described piston base is provided with gland nut, and described valve body cavity of resorption is communicated with by gland nut with between valve body epicoele.
Preferably, described detection feedback switch is electrical signal feedback switch.
Preferably, described valve body is provided with detection seat, and described detection seat is made up of pressure gauge base and locking swivel nut, and described locking swivel nut is socketed on valve body, and described pressure gauge base runs through and is socketed on locking swivel nut, and is close to valve body.
Returnning spring is set between sealing nut and piston by adopting and the form of gland nut is installed on piston after the utility model adopts said structure, make valve body upper and lower cavity pressure equal, guarantee piston rest seals, and the detection feedback switch adopted effectively detects valve body pressure, effective monitoring valve event situation, put only because of mechanical wear, and cause heptafluoro-propane to be wasted, avoid in use causing Loss of Life and property.

In figure: 1, valve body, 2, seal arrangement, 3, piston, 4, detect feedback switch, 6, Returnning spring, 7, locking nut, 8, sealing nut, 10, working masks, 11, O type circle, 12, seat is detected, 13, pressure gauge base, 14, gland nut, 15, locking swivel nut.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in the figure, a kind of Septenary-fluorine propane container valve of band signal feedback means, it is characterized in that: be made up of valve body 1, seal arrangement 2, piston 3, detection feedback switch 4, piston 3 is installed on the inner chamber of valve body 1, and match with valve body 1 position, described valve body 1 top socket is provided with seal arrangement 2, is provided with Returnning spring 6 between seal arrangement 2 and piston 3, described detection feedback switch 4 is installed on valve body 1, and with valve body 1 inner space.
Preferably, described seal arrangement 2 is made up of locking nut 7, sealing nut 8 and working masks 10, described locking nut 7 is socketed on sealing nut 8 top, be provided with working masks 10 between described locking nut 7 and sealing nut 8, described working masks 10 is corresponding with sealing nut 8 position.
Preferably, described sealing nut 8 is socketed on valve body 1, is provided with O type circle 11 between described valve body 1 and sealing nut 8.
Preferably, be provided with gland nut 14 bottom described piston 3, described valve body 1 cavity of resorption is communicated with by gland nut 14 with between valve body 1 epicoele.
Preferably, described detection feedback switch 4 is electrical signal feedback switch.
Preferably, described valve body 1 is provided with and detects seat 12, and described detection seat 12 is made up of pressure gauge base 13 and locking swivel nut 15, and described locking swivel nut 15 is socketed on valve body 1, described pressure gauge base 13 runs through to be socketed on locks swivel nut 15, and is close to valve body 1.
Under normal state, valve body 1 air inlet body is connected with container, pressure is together had in container, now the aperture of air pressure in valve body 1 on gland nut 14 makes epicoele the same with container intracavity pressure, valve body 1 epicoele is under the active force of Returnning spring 6, internal piston 3 is made to be in standstill seal state, when 10 explosion of epicoele working masks, valve body 1 upper cavity pressure reduces instantaneously, piston 3 now in valve body 1, under the pressure of container intracavity, moves upward, meanwhile, detect feedback switch 4 to be also under pressure at this moment, thus detection trigger feedback switch 4 actuating signal.
The above is preferred implementation of the present utility model; certainly the interest field of the utility model can not be limited with this; should be understood that; for those skilled in the art; the technical solution of the utility model is modified or equivalent replacement, do not depart from the protection domain of technical solutions of the utility model.
