Description
Technical field
The present invention relates to a kind of for fire protection sector, ceiling type is installed, keep airtight with openings in the ceiling, adapter from pipeline to furred ceiling is convenient, under operating pressure extinguishing medium is accelerated by wortex device supercharging whirling, spurts, spreads to decompose through a plurality of tangential spray orifices and vaporize, and spurt by predetermined angular, its setting space reaches 5 meters, and maxi-mum height is 6 meters, belongs to fire-fighting fire extinguishing, controls fiery field.
Background technology
Nozzle among the existing GB GB25972-2010 " gas extinguishing system and parts ", the connecting branch of nozzle and pipeline needs in situ quantitation, customization, to adapt to the distance of pipeline and decorative roof palte, because the impacts such as vibration, sedimentation, it is poor inferior uneven that the height of nozzle evagination decorative roof palte often seems, nozzle and perforation of top plate place are without airtight measure; Can not satisfy between clean room, hazardous chemical workshop, high-accuracy assembly shop, dustproof sterile food/medical occasion requirement, the engineering application requirements of the short protective zones such as such gas nozzle can not satisfy between cabin, testing equipment, cable tunnel be set.
Gas nozzle outlet of today is for open in usual, and insect and corrosivity pernicious gas, dust are easily invaded shower nozzle, pipe network, valve, and obstruction, corrosion-damaged lifetime of system affect the atomized spray effect simultaneously.
Current gas nozzle does not arrange wortex device, and spray orifice is straight hole, and the medicament atomizing is insufficient, unstable, and it is not good enough to spurt the vaporization diffusion effect.
Existing gas nozzle is column structure, and protruding dew is too much under the decorative roof palte, can not adapt in the cabin, laboratory, control rack, the application demand in cable tunnel, the short space such as spray paint between baking finish.
Summary of the invention
In order to solve at the scene pipe arrangement of conventional gas nozzle, the protruding dew of nozzle is highly wayward, and is dustproof, not airtight, be not suitable with problem airtight, clean guard plot.The invention provides a kind of embedded gas nozzle, nozzle is the dimpling circular arc type, nozzle protrudes top board less than 25mm, screw rod joint, the upper and lower lock solid structure that tunes of sprayer body straight thread have been designed, the vertical range deviation that adapts to extinguishing chemical conveyance conduit and decorative roof palte, sprayer body and openings in the ceiling adopt corrugated gasket, realize multiple-sealed; Nozzle entrance studs with wortex device; Nozzle has several uniformly to spurt the hole and inner chamber is tangent, deflects down 27 °, and spurting the hole has the diffusion tapering, the outer rim rounding; Nozzle outside cover has dust cover.
The present invention is achieved in that gas nozzle is comprised of locking nut, screw rod joint, wortex device, red copper pad, sprayer body, O RunddichtringO, nozzle, corrugated gasket, dust cover.The import of screw rod joint and conveyance conduit join, and outlet is joined with sprayer body, and is fastening by locking nut, adopt red copper pad and thread locking agent sealing; Cover has corrugated gasket and top board to keep airtight on the sprayer body; Nozzle entrance is embedded with wortex device, screws to embed in the sprayer body screw socket, adopts the sealing of O RunddichtringO; Dust cover is enclosed within the nozzle cylindrical.When spurting, extinguishing medium enters the wortex device of nozzle by screw rod joint inner duct, and carry out the vortex atomizing and accelerate, each tangential taper hole of flow nozzle dust cover that outwards spurts, blows off afterwards, vaporization diffuses to whole guard plot rapidly.
The invention has the beneficial effects as follows: eliminated the problem that on-the-spot pipe arrangement, nozzle and top board just differ; Realized at application requirements clean, airtight protection zone; Improve the atomizing of nozzle vortex, spurted diffusion; Spurt that medicament atomizing is faster, medicament is more evenly distributed, and has improved blow-off velocity, stopped nozzle, pipeline obstruction, be subjected to etching problem.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is section of structure of the present invention.
Fig. 2 is outline drawing of the present invention.
Fig. 3 is the vital part among the present invention: sprayer body figure.
Fig. 4 is the vital part among the present invention: nozzle figure.
Sprayer body: head is oblate type, and endoporus is processed with straight thread, and cylindrical is milled with flat filament, be convenient to screw rod joint height up and down, make on the sprayer body corrugated gasket on plane be adjacent to top board and form several sealing ring, outlet is provided with O RunddichtringO right angle groove, is connected sealing with nozzle.
Nozzle: the dimpling circular arc type, there are several uniformly to spurt the hole and inner chamber is tangent, deflect down 27 °, spurting the hole has the diffusion tapering, the outer rim rounding.
Wortex device: import and export as coniform, the guiding flow media reduces friction loss, several inclined holes that periphery is uniform, and inclined hole and wortex device angle are 65 °, and inclined hole is along in the tangent line inclined to one side 14 °, wortex device and nozzle are that interference is assembled.。
The screw rod joint: import is R21, and " screw thread exports and is M24 * 1.5 straight threads, and inner chamber Φ 16 is through hole.
Corrugated gasket: adopt the mold pressing butyronitrile rubber, shore hardness is 65-70, and section is corrugated, forms sealing astragal in 3 roads behind the upper-lower compacting.
Dust cover: adopt the engineering plastics mold pressing to form, with nozzle cylindrical interference fit, under≤0.2MPa air pressure, come off.
The present invention solves the technical scheme that its technical problem takes:
Press the core component of this shower nozzle of hydrodynamics three dimensional design--nozzle, have several uniformly to spurt the hole and inner chamber is tangent, deflect down 27 °, spurting the hole has the diffusion tapering, the outer rim rounding.Wortex device aperture, hole count, deflection angle become certain interactive, restricting relation with aperture, hole count, duct tapering, the outlet circular arc in nozzle peripheral jet hole.
