Specific embodiment
This case is described in further detail With reference to embodiment.
This case is related to a kind of temperature-sensitive distributing valve ejecting device 4, as shown in Figure 1-3, include mainly valve body 41, sealing piston
42 and temperature-sensitive glass spray head 43.
Valve chamber is equipped in valve body 41, there is valve chamber air intake 411, gas outlet 412 and pressure release to start mouth 413, wherein
The inner end of air intake 411 is equipped with seal 414, preferably, air intake 411 and pressure release starting mouth 413 are coaxial arrangement, gas outlet
412 be side opening structure, is arranged in a mutually vertical manner with air intake 411 in axial.
Temperature-sensitive glass spray head 43 is mounted on pressure release starting mouth 413；Preferably, pressure release starting mouth 413 is equipped with valve deck 47,
Temperature-sensitive glass spray head 43 is mounted on valve deck 47.It is equipped with temperature-sensitive glass 431 in temperature-sensitive glass spray head 43 and is supported by temperature-sensitive glass 431
Set the sealing-plug 432 of sealing.When temperature-sensitive glass 431 ruptures, sealing-plug 432 is opened, and pressure release starting mouth 413 is connected to extraneous big
Air pressure.This case is ingenious to be used to play temperature-sensitive starting effect using temperature-sensitive glass spray head 43, and the injection equipment of device is designed as by feeling
42 structure of sealing piston except warm glass spray head 43 carrys out split type realization.
Sealing piston 42 is set in the valve chamber of valve body 42, is formed with sealing piston room 421 in the sealing piston 42, this is close
Envelope piston chamber 421 opening both is realized towards pressure release starting mouth 413 to be connected setting, and the bottom of sealing piston room 421 is towards close
413 setting of sealing, and the bottom is configured to the sealing 422 matched with seal 413, when the sealing of sealing piston 42
422 with 413 inconsistent cooperation of seal when, sealing piston 42 realizes that the side wall of sealing piston 42 is lucky at this time to seal 413
Gas outlet 412 is aligned to be sealed effect to it.
The bottom area of 421 inside of sealing piston room is greater than the open area of seal 413, so when sealing piston 42 is in
When sealing 413 state of seal, and when gas pressure phase suffered by 422 two sides of sealing, due to compression area ratio
Difference, sealing piston 42 can automatically keep down force not by any mechanical external force and seal seal 413.
In order to ensure automatic-sealed effect, the compression of the open area of the bottom area and seal 413 of 421 inside of sealing piston room
Area ratio control is that 5:1-15:1 is preferable, and preferred compression area ratio is 10:1.
The piston aperture 4221 being connected with sealing piston room 421 is offered on the sealing 422.It is also opened on valve body 41
Equipped with faulty action preventing pin hole 415, activity is plugged with faulty action preventing bolt 44 in the faulty action preventing pin hole 415, is inserted by the faulty action preventing
Pin 44 limits sealing piston 42 so that sealing 422 is sealed effect to seal 4413 toward 413 direction of seal.It is anti-error
The design of dynamic bolt 44 plays false action-proof use, and installs conducive to the ingenious application of this case device.
Preferably, input interface 45 is installed on air intake 411, output interface 46 is installed on gas outlet 412, the input
Interface 45 and output interface 46 be set on valve body 41 and side opening translation interface external member, input interface 45 and output
The interval of interface 46 is arranged and has constituted embedded mounting groove 49.Realize that temperature-sensitive distributing valve is sprayed by simply installing translation interface external member
Its controllable distribution importing for entering gas and outlet of head device and Guide spray, and can be by whole device by embedded mounting groove 49
Simple again firmly sandwiched on plate body, particularly suitable for flexibly installing in the drawer box box wall of drawer type extinguishing device, input is connect
Mouth 45 is corresponding positioned at inner side of the box wall, and output interface 46 is corresponding to be located at box wall outside, goes out conducive to accessing gas source, box in box and spraying outside
Fire, faulty action preventing bolt 44 is corresponding to be conducive to operation on the outside of drawer box, and design is sharp outwardly outside drawer box for temperature-sensitive glass spray head 43
In detection induction effect.
Preferably, the side of input interface 45 and output interface 46 opening is equipped with homoaxial at least two groups, in practice may be used
It adjusts as needed, realizes the adjusting and the fire extinguishing of controllable Guide spray in gas source access direction.In order to be conducive to sealing joint,
Sealing ring 482,483 is respectively equipped between input interface 45 and valve body 41, between output interface 46 and valve body 41.
Preferably, two groups of sealing elements 481 are arranged in sealing piston 42 side by side, for sealing against each other with 41 inner sidewall of valve body
Effect.In addition, sealing 422 is equipped with groove, the gasket 423 for cooperating with seal 414 is installed, this is close in groove
Gasket aperture 4231 corresponding with piston aperture 4221 is offered on packing 423.
In the installation application of this case temperature-sensitive distributing valve ejecting device, before accessing gas source, faulty action preventing bolt 44 is plugged on faulty action preventing
In pin hole 415, the sealing 422 of sealing piston 42 makees sealing state to seal 414.Gas is accessed on input interface 45
Source, gas will push sealing piston 42, and sealing piston 42 has 44 stop of faulty action preventing bolt and cannot move up, the sealed piston of gas source
Piston aperture 4221 on 42 is inflated to sealing piston room 421, until 421 pressure of sealing piston room is equal to bleed pressure, at this point,
Faulty action preventing bolt 44 is taken out, since 42 upper and lower faces gas pressure of sealing piston is equal, compression area is than different, sealing piston
42 automatic down forces seal seal 414, and gas cannot discharge.When the temperature sensing glass ball 431 of pressure release starting mouth 413 is broken
It splits and opens, 421 air venting of sealing piston room, sealing piston 42 moves up under gas source promotion, seal 414 is opened,
Gas is externally vented through output interface 46.
The above is only the preferred embodiment of the present invention, it is all done with the utility model claims range it is equal
Deng variation and modification, the range of the utility model claims should belong to.
