Abstract
The invention relates to a water-mist nozzle, belonging to the field of fire protection, which is sealed usually, automatically starts to spray water mist when sensing a preset temperature and divides water flow into fine water drops of smaller than 120 microns. The high-pressure closed water-mist nozzle consists of a plurality of uniformly distributed side nozzles in shapes of cone, wherein a water inlet is provided with a protruded ball filter screen, and a spindle, a temperature-sensing glass ball and an O-ring sealing structure are arranged in the water inlet, thus the nozzle keeps a closed state. According to the high-pressure closed water-mist nozzle, the problems of undue interference damage, increased power of a water pump and oversized diameters of a valve and a pipe caused by a situation that a conventional opening type water-mist nozzle immediately sprays after a system starts and also sprays in a nonfire area are solved; in addition, the water-mist nozzle is additionally provided with a filter screen and utilizes a universal-interface thread so as to be convenient to construct. The high-pressure closed water-mist nozzle is provided with a spring, the spindle, a temperature-sensing glass ball and a glass ball frame seat, and is sealed usually; and on fire, the glass ball senses temperature to expand and blast, the spindle moves forwards under the action of water pressure of an inlet, and pressure water is atomized by each atomizing core and each nozzle to spray for extinguishing fired parts. The high-pressure closed water-mist nozzle has wide application prospect to archives, libraries, vaults, control rooms, tobacco bins and the like.
Description
Technical field
The present invention is novel to relate to a kind of fire protection sector that is used for; Be in closed condition by O RunddichtringO, temperature-sensitive glass marble, mandrel axial seal structure at ordinary times; Temperature-sensitive glass marble perceive heat flow expansion explosion during fire, mandrel displacement forward under spring and intake pressure acting in conjunction, pressure flow gets into respectively atomize core, spray nozzle; Current are resolved into the fine mist spray head less than the fine and closely woven water droplet ejection of 120um, belong to fire-fighting fire extinguishing, control fire, fire prevention field.
Background technology
Existing GB GB5135.5-2003 waterfog head.Rated operating pressure is on the low side, is 0.35MPa; Outlet is often opened; Droplet is thicker, and flow is bigger than normal, does not have dust cover and filter screen.
Existing waterfog head does not have dust cover, and the dust in the zone of protection, greasy dirt get into nozzle interior, gather plug nozzle hole and spraying core, influence atomizing effect even spray and lost efficacy.
Present filter screen is the plane, and the flow resistance loss is bigger; And do not have the reinforcement locked mechanism, under the high-pressure high-flow water impact, be prone to the distortion that stretches, stop up atomizing core and spray nozzle hole.
Existing fine mist spray head is an open architecture, does not have high voltage bearing hermetically-sealed construction, when water mist system starts; All fine mist spray heads spurt in the guard plot; Even also spray at the non-place that catches fire, bring interference, loss, cause the configuration of water pump output, power, valve and pipeline to increase.
The connecting thread of existing heavy pressure fine spray shower nozzle is special-purpose straight thread, and special-purpose transition plumb joint, gasket seal need be set, and construction technology is more numerous and diverse, and expense rises.
Summary of the invention
For solve conventional fine mist spray head in the excessive sprinkling at the non-place that catches fire, screen pack intensity is on the low side, shower nozzle is connected need special screw thread interface with pipeline, core and the susceptible to plugging problem in spray nozzle hole atomize.The present invention is novel to provide a kind of high pressure enclosed fine mist spray head, and connecting thread is designed to R
21/2 " general-purpose interface is established protrudent sphere and is strengthened filter screen in the water inlet, spring, mandrel, O RunddichtringO, temperature-sensitive glass marble hermetically-sealed construction are set, each spray nozzle dress dust cover.Not before the explosion, shower nozzle is anhydrous to be discharged at the temperature-sensitive glass marble; Have only when environment temperature, when flue gas stream reaches 57 ℃, temperature-sensitive glass marble response explosion, it is inner that pressure flow gets into shower nozzle, spurts fire extinguishing through atomization core, spray nozzle atomizing to fire position.
The novel high pressure enclosed fine mist spray head that is achieved in that of the present invention is made up of lock plunger, protruding ball filter screen, mandrel, sprayer body, temperature-sensitive glass marble, glass marble skeleton frame, spring, O RunddichtringO, atomizing core, spray nozzle, dust cover.Be in the axial seal state by sprayer body, mandrel, spring, O RunddichtringO, temperature-sensitive glass marble supporting construction at ordinary times; Temperature-sensitive glass marble perceive heat flow expansion explosion is cracked during fire; Mandrel displacement forward under spring and intake pressure acting in conjunction; The O RunddichtringO of mandrel and back porch thereof moves sealing in the taper hole that is pressed into the glass marble skeleton frame; Pressure flow gets into respectively atomize core, spray nozzle, current is resolved into less than the fine and closely woven water droplet of 120um spurt, and dust cover comes off simultaneously.Flame, flue gas stream do not reach rated temperature in the guard plot; The not explosion of temperature-sensitive glass marble starts, and fine mist spray head does not spurt, and realizes the ideal effect that where catches fire and where spurt; Avoided spurting of non-fire place, more become science, rationally of the configuration of water pump, valve, pipeline.
The novel beneficial effect of the present invention is: eliminated open type fine mist spray head existence is excessively spurted at non-fire place interference and infringement when water mist system starts; Reduced the configuration of water pump, valve, pipeline; Shower nozzle is connected employing R with pipeline
21/2 " conventional screw thread is convenient to construction; The shower nozzle water inlet is provided with protruding ball and strengthens 100 height of eye precision filter screens, each spray nozzle configuration dust cover, the blockage problem of stopped from pipe interior and external environment condition two aspects to atomize core and spray nozzle.
