Description

Double glass marble watering fire-fightings spray head

Technical field

The utility model belongs to fire-fighting equipment technical field, sprays head more particularly to a kind of double glass marble watering fire-fightings.

Background technique

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 spray head is a kind of most popular spray head, sagging to be installed on water supply branch pipe, and the shape of watering is to throw Object type sprays to ground for the 80~100% of total Water, and protection has the room of furred ceiling, in furred ceiling arranged beneath spray head, Ying Caiyong Sagging type spray head or furred ceiling type spray head.

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) spray head, early stage inhibition quick response (ESFR) spray head, special applications (CMSA, CHSA) spray Head, shower head, water mist spraying 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 spray head can be divided into 57,68,79,93,141 DEG C etc.；Fusible alloy nozzle can divide It is 72,74,101 DEG C etc., is divided by the discharge coefficient (K) of spray head, 80,115,161,202,242,282,363 can be divided into Deng.

According to the regulation of national " Code for fire protection design of buildings ", the fire-fighting system of industry and civil buildings is all largely used Fire-fighting spraying head.In the glass spheres of double bulb sprinkler heads, filled with the high organic solution of thermal expansion coefficient, under room temperature, The shell of sphere can bear certain support force, guarantee the sealing performance of spray head, 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 water flow punching, to start sprinkling fire, plays fire extinguishing Effect.

Spray head is usually in close state, 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 is: notice 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, stops spraying water to accident spray head 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 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.

Summary of the invention

In order to solve above-mentioned technical problem, the utility model provides a kind of double glass marble watering fire-fightings and sprays head, It is simple mainly for developing a kind of structure, it prevents from deforming, it is easy for installation, and double glass marbles are equipped with, plug screw rod is reusable, Good in economic efficiency glass marble watering fire-fighting sprays head, can effectively solve the problem that and accidentally opens because glass marble explosion causes fire-fighting to spray head The problems such as dynamic, it is low that fire-fighting sprays a functional reliability, sprays header structure intensity difference, easily-deformable by external force.

The technical solution adopted in the utility model is as follows:

The watering fire-fightings of double glass marbles spray head, including valve seat, sealing ring, plug, plug screw rod, metal baffle, support, the One glass marble, the second glass marble, support clamping ring, splash box, reserving hole and glass marble washer；Valve seat is annulus column knot There are screw thread in structure, outer surface, can be connect by screw thread with fire protection pipeline respective valves；Plug is semicircle sphere structure, is located at valve seat Centre is equipped with sealing ring with the contact surface of valve seat, passes through welded connecting with plug screw rod；Plug screw rod is cylindrical structure, position In plug lower part, plug screw rod lower part is equipped with reserving hole, and the first glass marble and the second glass marble pass through reserving hole and plug Screw rod is connected and fixed；First glass marble and the second glass marble are cylindrical structure, high organic molten of inside filling thermal expansion coefficient Liquid, outside are equipped with glass marble washer；Support is semi arch structure, is welded to connect with valve seat and support clamping ring, in the holder on Portion symmetrically opens up 4 metal baffles；Splash box is anti-arc structure, by being welded to connect in support clamping ring lower part.

Further, valve seat, plug, plug screw rod, metal baffle, support, support 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 thermal expansion coefficient 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, support tetragonal symmetry is arranged, angle in 90 ° between adjacent support, inner hollow, is equipped with gold in middle and upper part Belong to baffle, is fixed by the first glass marble and the second glass marble of non-explosion, when fire-fighting sprays head starting 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.

The utility model has the beneficial effects that

The effect and advantage of the utility model are that structure is simple, secured, and easy for installation, section components are reusable, warp It helps profitable, double glass marble Redundancy Designs can effectively avoid because glass marble explosion causes fire-fighting to spray an error starting, improve fire-fighting Spray a functional reliability.
