The invention belongs to the field of fire fighting. The water mist spray nozzle is characterized in that: piston structures and spring structures are adopted; a plurality of small spray nozzles are combined circumferentially and the combination of the small spray nozzles presents a cylindrical appearance. According to the present invention, application difficulties of mutual interference or crossing between the routine spray nozzle or distribution branch pipes and deck or test platform or reaction kettle or reaction furnace are solved; after finishing the spraying, the water mist spray nozzle automatically resets and retracts to the initial position so as to conveniently restore operating; the self-pushing and spraying water mist spray nozzle is equipped with the springs, the piston rods, a filter, an adaptor, a piston cylinder, locknuts, a water mist spray nozzle core, the spray nozzles, a sprayer body; the self-pushing and spraying water mist spray nozzle has wide application prospect in the fields of war industry, electricity, chemical engineering, spaceflight, ship, metallurgy, subway and tunnel.
Description
Technical field
The present invention is novel to be related to a kind ofly for fire protection sector, adopts piston, spring structure, many circle-shaped combined types of little spray nozzle, and this fine mist spray head is straight-tube shape profile; Be installed at ordinary times safe place outside operation technique district, when fire, adopt intake pressure to promote fine mist spray head and back down technique stifle, stop up to precalculated position, High-Pressure Water atomization is resolved into and is less than the fine mist spray head that the fine and closely woven water droplet of 150um spurts; While stopping spurting, bounce back to voluntarily initial position, recover rapidly the operation in protected district, belong to fire-fighting fire extinguishing, control fire, protect cooling field.
Background technology
Existing standard GB/T 5135.3-2003 waterfog head, rated operating pressure is on the low side, is 0.35MPa; In use pushing tow, retraction automatically; Spurt droplet thicker, more than 400um; Water consumption is bigger than normal.
Waterfog head does not have auto-telescopic mechanism at present; waterfog head and join arm and protected robotic arm manipulation, produce flowing water facility and intersect, interfere, cannot meet fire extinguishing, security application requirement that deck class, cabin narrow space protection place, adhesiveness chemical fibre particle, jelly reactor stove, wind tunnel test platform, block testing stand, the electric equipment of super-pressure, the acute rotten medium of severe toxicity are produced.
Summary of the invention
For solve conventional waterfog head automatically pushing tow retraction, spurt the problem that droplet is thick, water consumption is large.The present invention is novel provides a kind of Self-pushing spray head for spurting water mist, is installed at ordinary times safe place outside operation technique district, adopts intake pressure to promote fine mist spray head and back down technique stifle, stop up and arrive precalculated position, the fine mist spray head that atomization is spurted when fire; While stopping spurting, bounce back to voluntarily initial position, recover rapidly the operation in protected district.
The present invention is novel be achieved in that Self-pushing spray head for spurting water mist by: locking nut (8), spray nozzle (1), screen pack (5), head body (3), O RunddichtringO (12), spring (10), atomization core (2), crossover sub (6), piston barrel (11), piston rod (9) form.Under acting force of the spring, fine mist spray head and piston rod are compressed in initial position at ordinary times; When sprinkling, import water pressure promotes piston rod and fine mist spray head moves outward, and High-Pressure Water is through atomization core, spray nozzle atomization ejection simultaneously; Spurt while end, piston rod and fine mist spray head bounce back to initial position under spring thrust.
The novel beneficial effect of the present invention is: in the time of servo condition, Self-pushing spray head for spurting water mist is arranged on safety, concealed location, do not interfere operation, deck, the test platform of process production line, the operation of production still stove, special production medium that is high-risk, high rotten, that adhere to also can not impact this shower nozzle.When startup, Self-pushing spray head for spurting water mist backs down technique and blocks plug, lid, makes a forcible entry into protection zone and implements to spurt fire extinguishing operation.Spurt after end, the original position of Self-pushing spray head for spurting water mist automatic retraction, deck, test platform, production still stove, streamline etc. can resume operation rapidly.
Brief description of the drawings
Further illustrate the present invention is novel below in conjunction with drawings and Examples.
Fig. 1 is the novel section of structure of the present invention.
Fig. 2 is the novel outline drawing of the present invention.
Fig. 3 is that working condition chart is spurted in the novel jacking of the present invention.
Screen pack: be mold pressing hemispherical stainless steel enhancement mode, 80 orders, outer perimeter strengthens with stainless steel sheet| shroud ring, and screen pack is clamped between head body and crossover sub; Negotiability is same order number, with the flat screen pack of bore 3 times.
Atomization core: be bull saw shape, long pitch atomization core, conehead water inlet diversion Design, forms and have multiply water and lose rotation, again to the kinetic energy current of preshoot.
Spray nozzle: outside is provided with hexagonal fastening surface, inner chamber is made up of straight hole mixed flow section, circular arc contraction section, small straight hole spout section and indent conical surface section; The indent conical surface of outlet side design, the adverse effect of the reaction force while having avoided pushing tow to the small straight hole spout of spray nozzle section.
Piston rod: head cylindrical cover has O RunddichtringO, and bar portion is embedded with stainless steel spring; Head, for expanding arc water inlet, reduces the loss of flood peak, and piston rod is by piston barrel inner chamber and locking nut hole positioning and guiding; Piston rod, under the thrust of spring, moves to desired location to influent side at ordinary times; While spurting, piston rod produces the jacking force of 1520N under 4MPa minimum working pressure power.
Crossover sub: influent side and piston rod join, water outlet side and head body are joined; Crossover sub and piston rod, head body adopt the radial seal of O RunddichtringO; By the pretightning force of crossover sub setting spring and the servo position of fine mist spray head.
The technical scheme that its technical problem of the novel solution of the present invention is taked is:
Adopt spring precommpression piston rod construction by design in the piston barrel of fine mist spray head, radially circle sealing, bull saw shape, long pitch atomization core atomization core.Under 4MPa minimum working pressure power, produce the jacking force of 1520N.Spray nozzle outlet side is designed to the indent conical surface, the adverse effect of the reaction force of the generation while having avoided powerful pushing tow obstruction, stifle to spray nozzle spout straight apertures.
