Abstract
A fire sprinkler for glasses of fire protection and separation belongs to the technical field of fire-fighting instruments. The fire sprinkler comprises a frame with a water outlet, plug mounted at the water outlet of the frame, a glass ball mounted at the lower end of the plug and a yoke arm mounted on the glass ball, and is characterized in that the lower end of the water outlet is fixedly connected with a water distribution disc with a water jet; a through hole allowing the mounting of the plug and the falling-in of the plug to block the through hole is formed on the water distribution disc; and the yoke arm is fixedly connected with the lower surface of the water distribution disc. The fire sprinkler has the advantages that water can be uniformly sprayed on and completely covers the surface of the glass, and a glass wall can be well protected.
Description
Technical field
The utility model relates to the shower nozzle that a kind of glass fire separation is used.Belong to the extinguisher technical field.
Background technology
When breaking out of fire, for preventing fire spread, must be with fire control at certain area.Present common way is at interior of building fire separation to be set.Ordinary circumstance arranges the fire separation things such as fire wall, and some building adopts glass wall to carry out fire separation in order to reach inner visually penetrating effect.Adopt glass to carry out fire separation and generally be divided into again two kinds of situations, a kind of is to adopt flame resistant glass, a kind of employing safety glass.Adopting flame resistant glass to separate the in actual applications larger problem of existence, mainly is that the fire resistance period that will reach code requirement requires so that the cost of manufacture of flame resistant glass is very high.Adopting safety glass to separate in actual applications also existing problems, mainly is that the fire resistance period of safety glass does not reach code requirement.Present solution is to adopt traditional sprinkler tip that glass is sprayed to improve its fire resistance period.Traditional sprinkler tip (referring to standard GB/T 5135.1-2003) is comprised of the plug of splash box, glass marble and the glass marble top of the framework that contains delivery port, the yoke arm that is fixed in framework below, tie-down yoke arm below and framework contact position etc. usually.The glass marble rear expansion blast of being heated comes off, and discharges plug, is the plug self falling of free state, and water is beaten on the splash box of yoke arm lower end from the delivery port ejection of framework, splash box to water distribution after so that be sprayed on glass to its cooling.The shortcoming of this sprinkler tip is that its watering shape is parabolic type, is sprayed on the glass surface and can't be evenly arranged, and the complete cover glass surface of water, can not carry out good protection to glass.
The utility model content
The purpose of this utility model is the above-mentioned shortcoming that overcomes existing sprinkler tip, provide a kind of can be at glass surface water distribution uniformity and the complete applicator used of the glass fire separation of cover glass surface.
The applicator that the glass fire separation of realization the utility model purpose is used, the yoke arm that comprises the framework that contains delivery port, the plug that is installed in the framework delivery port, the glass marble that is installed in the plug lower end and mounting glass ball, it is characterized in that being connected with a water distributing tray that has water jet in described framework delivery port lower end, offer one in water distributing tray through hole plug and that can fall into for plug shutoff is installed, described yoke arm is fixed on the lower surface of water distributing tray.
The same with prior art, under accurate working condition, the plug of this shower nozzle gets lodged in the water outlet of shower nozzle framework in the position-limiting action lower seal of glass marble.Glass marble blast during breaking out of fire, discharge plug, plug moves downward with respect to water distributing tray under the effect of deadweight and hydraulic pressure, abdicate and fall within behind the water stream channel in the through hole that water distributing tray offers and with this through hole shutoff, avoided water from this hole, to flow out, made under the effect of the water jet of water distributing tray, to form fan-shaped tentiform from shower nozzle framework delivery port current out and evenly spray to glass surface to realize the strong cooling to the glass fire separation.
Compare with existing sprinkler tip, the utility model has the advantages that evenly to be sprayed at water on the glass surface and complete cover glass surface, can carry out good protection to glass partition.
Below in conjunction with drawings and Examples the utility model is further specified.

The specific embodiment
Shown in Fig. 1～5, the formation of the applicator that the fire separation of this glass is used comprises the framework 1, the plug 2 that is installed in the framework delivery port that contain delivery port, is installed in the glass marble 3 of plug 2 lower ends and the yoke arm 4 of mounting glass ball, be connected with a water distributing tray 6 that has water jet 5 in described framework delivery port lower end, offer one in water distributing tray 6 through hole 7 plug and that can fall into for plug shutoff is installed, described yoke arm 4 is fixed on the lower surface of water distributing tray 6.8 is the rubber seal of plug among the figure.
This shower nozzle withstands plug 2 by yoke arm 4 fixing glass marbles 3 when quasi-operating status, plug is blocked the framework delivery port, and water seal is lived.When temperature reached glass marble setting operating temperature after fire occured, glass marble 3 explosions came off, and plug 2 moves down and fall into through hole 7 and shutoff through hole 7 under deadweight and Water Pressure.Water flows out from the framework delivery port, forms fan shapes through the water jet 5 of water distributing tray 6 water is sprayed on the glass surface.
Fig. 6 has provided the schematic cross-section of the water jet 9 of another kind of water distributing tray.Form the water curtain of different in width to adapt to different demands by different cross sectional shapes.
