Description
Technical field
The present invention relates to a kind of fire protection sector that is used for, adopt piston, spring structure, the straight-tube shape profile; Be installed on safe place outside the operation technique district at ordinary times, adopt intake pressure promotion piston rod, fine mist spray head to back down the technology stifle, stop up during fire, the fine mist spray head that spurts less than the fine and closely woven water droplet of 150um is resolved in the High-Pressure Water atomizing to the precalculated position; Bounce back to initial position when stopping to spurt voluntarily, recover the operation in protected district rapidly, belong to fire-fighting fire extinguishing, control fire, protection cooling field.
Background technology
Existing standard GB 5135.3-2003 waterfog head, rated operating pressure is on the low side, is 0.35MPa; In use pushing tow, retraction automatically; It is thicker to spurt droplet, more than 400um; Water consumption is bigger than normal.
Waterfog head does not have automatic telescoping mechanism at present; waterfog head and join arm and protected robotic arm manipulation, produce the flowing water facility and intersect, interfere can't satisfy 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
Can not push back in advance automatically and contract, spurt the problem that droplet is thick, water consumption is big in order to solve conventional waterfog head.The invention provides a kind of pushing tow voluntarily and spurt fine mist spray head, be installed on safe place outside the operation technique district at ordinary times, adopt intake pressure promotion piston rod, fine mist spray head to back down the technology stifle during fire, stop up arrival precalculated position, the fine mist spray head that atomizing is spurted; Bounce back to initial position when stopping to spurt voluntarily, recover the operation in protected district rapidly.
The present invention be achieved in that voluntarily pushing tow spurt fine mist spray head by: locking nut (8), spray nozzle (1), screen pack (5), head body (3), O RunddichtringO (12), spring (10), atomizing core (2), crossover sub (6), piston barrel (11), piston rod (9) are formed.Fine mist spray head and piston rod are compressed in initial position under acting force of the spring at ordinary times; During sprinkling, the import water pressure promotes piston rod and fine mist spray head moves outward, and High-Pressure Water is through atomizing core, spray nozzle atomizing ejection simultaneously; Spurt when finishing, piston rod and fine mist spray head bounce back to initial position under spring thrust.
The invention has the beneficial effects as follows: when servo condition, pushing tow spurts fine mist spray head and is installed in safety, concealed location voluntarily, 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 can not impact this shower nozzle yet.During startup, pushing tow spurts fine mist spray head and backs down technology and block plug, lid voluntarily, makes a forcible entry into the protection zone and implements to spurt the fire extinguishing operation.After spurting end, pushing tow spurts the fine mist spray head original position of withdrawal automatically voluntarily, and deck, test platform, production still stove, streamline etc. can resume operation rapidly.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a section of structure of the present invention.
Fig. 2 is an outline drawing of the present invention.
Fig. 3 spurts working condition chart for jacking of the present invention.
Screen pack: be mold pressing hemispherical stainless steel enhancement mode, 80 orders, outer perimeter strengthens with the stainless steel sheet| shroud ring, and screen pack is clamped between head body and the crossover sub; Negotiability is with the order number, with 3 times of the flat screen pack of bore.
The atomizing core: be bull saw shape, long pitch atomizing core, conehead water inlet diversion Design forms and promptly has multiply water and lose rotation, again to the kinetic energy current of preshoot.
Spray nozzle: the outside is provided with fastening of hexagonal, and 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 reaction force when having avoided pushing tow is to the adverse effect of the small straight hole spout of spray nozzle section.
Piston rod: the head cylindrical is with the O RunddichtringO, and bar portion is embedded with stainless steel spring; Head reduces the loss of flood peak for expanding the arc water inlet, and piston rod is by piston barrel inner chamber and locking nut hole positioning and guiding; Piston rod moves to desired location to influent side under the thrust of spring at ordinary times; Piston rod produces the jacking force of 1520N when spurting under 4MPa minimum working pressure power.
Crossover sub: influent side and piston rod join, and 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 present invention solves the technical scheme that its technical problem takes:
Adopted spring precommpression piston rod construction by design in the piston barrel of fine mist spray head, radially O type circle sealing, bull saw shape, long pitch atomizing core atomizing core.Under 4MPa minimum working pressure power, produce the jacking force of 1520N.The spray nozzle outlet side is designed to the indent conical surface, and the reaction force of the generation when having avoided powerful pushing tow obstruction, stifle is to the adverse effect of spray nozzle spout straight apertures.
The specific embodiment
Spray nozzle is loaded in the head body screw with the atomizing core, head body is twisted in crossover sub, and crossover sub is loaded on piston rod top, and spring is embedded in piston rod and is placed in the piston cylinder body cavity, by the locking nut compression, piston rod utilizes piston barrel and locking nut hole guiding.At ordinary times by being pushed into the qualification position of crossover sub under following fine mist spray head of acting force of the spring and the piston rod; During sprinkling, intake pressure promotes piston rod and fine mist spray head backs down stifle, stops up to desired location, and High-Pressure Water is through atomizing core, spray nozzle atomizing ejection simultaneously; Spurt when finishing, piston rod and fine mist spray head bounce back to initial position under spring thrust, and deck, test platform, reactor stove, flowing water operation line etc. can resume operation rapidly.
