Description
Technical field
The utility model relates to fire-fighting equipment art, refers in particular to a kind of structure improved fire-fighting and spillsSprinkler head.
Background technology
In fire-fighting automatic fire extinguishing system, as one of people's lives and properties patron saint's sprinkler tip loadBearing and monitoring the condition of a fire and implement the two large missions that fight a fire, each sprinkler tip has specific protectionRegion, in the time of breaking out of fire, water is spilt and is put out a fire by the splash box of spray head, and fire water is passed throughSpray head evenly spills, and the intensity of a fire in this region is played to control. Conventional sprinkler tip divides conventionally at presentFor sagging type sprinkler tip, upright sprinkler, conventional sprinkler, sidewall sprinkler headDeng, wherein sagging type sprinkler tip is most popular a kind of shower nozzle.
Current sagging type sprinkler tip ubiquity poor sealing, the problems such as assembling inconvenience, andTime has been grown, and sealing ring, by aging, is bonded together plug and housing, while catching fire, and applicatorOn glass marble break, but because plug and housing are bonded together, plug cannot come off, and causes nothingThe serious consequence of method fire extinguishing.
Utility model content
In view of this, the utility model is for the disappearance of prior art existence, and its main purpose is to provideA kind of structure improved fire water spray nozzle, it can effectively solve the type sprinkler tip that hangs down under existing and existThe problem that poor sealing, assembling inconvenience and plug and housing are easily bonded together.
For achieving the above object, the utility model adopts following technical scheme:
A kind of structure improved fire water spray nozzle, includes housing, hard plastic plug, butterfly bulletSpring, sealing shroud, glass marble, screw and splash box; In this housing, be formed with cavity and runner, streamRoad is communicated with the bottom of cavity, and the bottom of cavity is formed with the first annular step surface and the from lower to upper successivelySecond ring step surface; This hard plastic plug can be arranged in cavity up and downly, and hard plastic is stifledHead top there is a bulge loop, this butterfly spring together with hard plastic plug produced by insert molding, butterflySpring is positioned at the below of bulge loop, and the outer peripheral edges of butterfly spring are butted on the first annular step surface, and this is closeBig envelope is sheathed on outside bulge loop, and the bottom surface of sealing shroud convexes with annular protrusion, and this annular protrusion is butted on secondOn annular table terrace, this glass marble is arranged in cavity, and it is stifled that the tip of glass marble presses on hard plasticThe top of head, screw cock is in the screw of case top, and the lower end of screw is butted on the round end of glass marblePortion, this splash box is riveted on the top of housing.
As a kind of preferred version, the lower end lateral surface of described housing is formed with the 3rd annular table terrace,On the 3rd annular table terrace, be embedded with sealing gasket.
As a kind of preferred version, described annular protrusion is two that internal and external partition arranges.
As a kind of preferred version, the upper end of described screw is filled with epoxy resin.
The utility model compared with prior art has obvious advantage and beneficial effect, particularly,As shown from the above technical solution:
By utilizing butterfly spring together with hard plastic plug produced by insert molding, make product componentReduce, be convenient to Product Assembly; And, convex with annular protrusion by the bottom surface in sealing shroud, protectingCard sealing reduces the contact area of sealing shroud and housing good time, and coordinates butterfly spring, hasEffect is avoided the appearance of sealing shroud and housing bonding phenomenon, and product serviceability is better.
For more clearly setting forth architectural feature of the present utility model and effect, below in conjunction with accompanying drawing and concreteEmbodiment is elaborated to the utility model.

Detailed description of the invention
Please refer to shown in Fig. 1, it has demonstrated the concrete structure of the preferred embodiment of the utility model,Include housing 10, hard plastic plug 20, butterfly spring 30, sealing shroud 40, glass marble 50,Screw 60 and splash box 70.
In this housing 10, be formed with cavity 11 and runner 12, runner 12 is communicated with the bottom of cavity 11, cavity11 bottom is formed with the first annular step surface 13 and the second annular table terrace 14 from lower to upper successively, withAnd the lower end lateral surface of described housing 10 is formed with the 3rd annular table terrace 15, the three ring-shaped stepsOn face 15, be embedded with sealing gasket 80, be connected to realize sealingly secure with outside.
This hard plastic plug 20 can be arranged in cavity 11 up and downly, hard plastic plug 20Top has a bulge loop 21, this butterfly spring 30 together with hard plastic plug 20 produced by insert molding, butterflyShape spring 30 is positioned at the below of bulge loop 21, and the outer peripheral edges of butterfly spring 30 are butted on the first annular step surfaceOn 13, sealing cover 40 is sheathed on outside bulge loop 21, and the bottom surface of sealing shroud 40 convexes with annular protrusion 41,This annular protrusion 41 is butted on the second annular table terrace 14, and this glass marble 50 is arranged in cavity 11, glassThe tip of glass ball 50 presses on the top of hard plastic plug 20, and screw 60 cocks are in housing 10 topsIn screw, the lower end of screw 60 is butted on the round end portion of glass marble 50, and this splash box 70 is riveted on housing 10Top.
