Description
Technical field
The invention belongs to fire-fighting equipment technical fields, and head is sprayed more particularly to a kind of double glass marble watering fire-fightings.
Background technology
Fire-fighting spraying head is used for spraying system of fire fighting, and when a fire, water is spilt by spray head splash box to go out
Fire is divided into sagging type sprinkler tip, upright sprinkler, conventional sprinkler, sidewall sprinkler head etc. at present.
Sagging type nozzle is a kind of most popular nozzle, sagging to be installed on water supply branch pipe, and the shape of watering is to throw
Object type sprays to ground by the 80~100% of total Water, and protection has the room of furred ceiling that should be used in furred ceiling arranged beneath nozzle
Sagging type nozzle or furred ceiling type nozzle.
It is divided by fire-extinguishing function concurrently or protection zone, sprinkler tip can be divided into ordinary sprinklers, dry sprinkler, household spray
Head expands area coverage watering（EC）Nozzle, early stage inhibit quick response（ESFR）Nozzle, special applications（CMSA,CHSA）Spray
Head, shower head, waterfog head, drencher etc..
Bulb sprinkler head suitable for light hazard class, hazard class, grave danger grade building, as hotel, shop,
The Workplace of dining room, various commercial buildings and environment temperature not less than 4 DEG C and warehouse etc..
It is divided by temperature grade, glass marble nozzle can be divided into 57,68,79,93,141 DEG C etc.；Fusible alloy nozzle can divide
It it is 72,74,101 DEG C etc., by the discharge coefficient of nozzle（K）It divides, 80,115,161,202,242,282,363 can be divided into
Deng.
According to country《Code for fire protection design of buildings》Regulation, industry and the fire-fighting systems of civil buildings all largely use
Fire-fighting spraying head.In the glass spheres of double bulb sprinkler heads, filled with the high organic solution of coefficient of thermal expansion, under room temperature,
The shell of sphere can bear certain support force, ensure the sealing performance of nozzle, when fire occurs, organic solution temperature increase and
It expands, until vitreum is broken, ball seat, sealing element is taken off after losing support by flow punching, to start sprinkling fire, plays fire extinguishing
Effect.
Spray head is usually closed, but due to unexpected factors and accident (such as artificial destruction, accidental impact, low coverage
, low temperature bursting by freezing close from heat source, product quality problem etc.), it is likely to that fire-fighting spraying head is caused surprisingly to erupt, once this occurs
Class accident, conventional processing method are：Notify fire protection control room, fire-fighting spraying water pump is shut down, close the fire-fighting system into
Water total valve, opens simultaneously emptying valve, and the water in the fire-fighting system pipeline is all emptied, waits for that accident spray head stops water spray
Afterwards, spray head is replaced.This process is at least also required to dozens of minutes, the fire water that during which accident spray head is sprayed, not only right
Loss directly or indirectly is caused in building, simultaneously as entire spraying system of fire fighting is at halted state and great
Security risk.
It is a glass marble that most of glass marble waterings, which spray head, at present, when glass marble occurs accidentally broken, applicator
It will start, certain loss is caused to people's lives and finance, on the other hand, most of glass marble watering fire-fightings spray head
Plug it is smaller, be it is disposable, it is more wasteful to plug.
Invention content
In order to solve above-mentioned technical problem, a kind of double glass marble watering fire-fightings of present invention offer spray head, mainly
It is a kind of simple in structure in order to develop, it prevents from deforming, it is easy for installation, and equipped with double glass marbles, plug screw rod is repeatable to be utilized, economical
Profitable glass marble watering fire-fighting sprays head, can effectively solve the problem that because glass marble explosion causes fire-fighting to spray an error starting, disappears
The anti-functional reliability that sprays is low, sprays header structure intensity difference, it is yielding by external force the problems such as.
The technical solution adopted by the present invention is as follows：
Double glass marble watering fire-fightings spray head, including valve seat, sealing ring, plug, plug screw rod, metal catch, bearing, the first glass
Glass ball, the second glass marble, bearing clamping ring, splash box, reserving hole and glass marble washer；Valve seat is annulus column structure, outside
There is screw thread on surface, can be connect with fire protection pipeline respective valves by screw thread；Plug is semicircle sphere structure, is located among valve seat,
It is equipped with sealing ring with the contact surface of valve seat, with plug screw rod by being welded to connect；Plug screw rod is cylindrical structure, is located at plug
Lower part, plug screw rod lower part are equipped with reserving hole, the first glass marble and the second glass marble and are connected by reserving hole and plug screw rod
Connect fixation；First glass marble and the second glass marble are cylindrical structure, and filling coefficient of thermal expansion high organic solution in inside is external
Equipped with glass marble washer；Bearing is semi arch structure, is welded to connect with valve seat and bearing clamping ring, top is symmetrically opened in the holder
If 4 metal catch；Splash box is anti-arc structure, by being welded to connect in bearing clamping ring lower part.
Further, valve seat, plug, plug screw rod, metal catch, bearing, bearing clamping ring and splash box are all made of resistance to
Corrode stainless steel metal material.
Further, the first glass marble with glass marble washer and the second glass marble are fixed by reserving hole, and stifled
Head screw rod constitutes overall structure.
Further, the coefficient of thermal expansion of organic solution is more swollen than the heat of organic solution in the second glass marble in the first glass marble
Swollen coefficient is high.
Further, bearing tetragonal symmetry is arranged, angle in 90 ° between adjacent bearing, inner hollow, and gold is equipped in middle and upper part
Belong to catch, is fixed by the first glass marble and the second glass marble of non-explosion, when fire-fighting, which sprays head, starts work, first
Glass marble and the second glass marble whole explosion, the pop-up of plug screw rod.
Further, sealing ring and glass marble washer use anti-corrosive rubber material.
Beneficial effects of the present invention：
The effect and advantage of the present invention is simple in structure, secured, and easy for installation, section components are repeatable to be utilized, good in economic efficiency,
Double glass marble Redundancy Designs can effectively avoid because glass marble explosion causes fire-fighting to spray an error starting, improves fire-fighting and sprays head work
Reliability.
