Description

The flush type gas nozzle

Technical field

The utility model relates to a kind of fire protection sector that is used for, and ceiling type is installed, and keeps airtight with the top board perforate; Convenient from the adapter of pipeline to furred ceiling, under operating pressure, extinguishing medium is quickened through wortex device supercharging whirling, spray orifice spurts, spreads to decompose and vaporizes through a plurality of tangentials; And spurt by predetermined angular; It is provided with spacing and reaches 5 meters, and suitable 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; Difference is inferior uneven because influences such as vibration, sedimentation, the height of nozzle evagination decorative roof palte often seem, nozzle and perforation of top plate place do not have airtight measure; Can not satisfy between clean room, hazardous chemical workshop, high-accuracy assembly shop, dustproof sterile food/medical occasion requirement, the practical applications requirement of 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 prone to invade shower nozzle, pipe network, valve, and obstruction, corrosion-damaged lifetime of system influence the atomized spray effect simultaneously.

Current gas nozzle is not provided with wortex device, and spray orifice is a 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 a 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, short space such as spray paint between baking finish.

Summary of the invention

In order to solve conventional gas nozzle pipe arrangement at the scene, the protruding dew of nozzle is highly wayward, and is dustproof, not airtight, incompatibility is airtight, the problem of clean guard plot.The utility model provides a kind of flush type gas nozzle; Nozzle is the dimpling circular arc type; Nozzle protrusion top board has designed screw rod joint, the upper and lower lock solid structure that tunes of sprayer body straight thread less than 25mm, adapts to the vertical range deviation of extinguishing chemical conveyance conduit and decorative roof palte; The ripple pad is adopted in sprayer body and top board perforate, realizes multiple-sealed; Nozzle entrance studs with wortex device; Nozzle has several to be uniformly distributed with to spurt the hole and inner chamber is tangent, deflect down 27 °, and spurting the hole has the diffusion tapering, the outer rim rounding; The nozzle outside is with dust cover.

The utility model is achieved in that gas nozzle is made up of locking nut, screw rod joint, wortex device, red copper pad, sprayer body, O RunddichtringO, nozzle, ripple pad, dust cover.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; Be with ripple pad and top board on the sprayer body and keep airtight; 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 gets into the wortex device of nozzle through screw rod joint inner duct, and carry out the vortex atomizing and quicken, each tangential taper hole of flow nozzle dust cover that outwards spurts, blows off afterwards, vaporization diffuses to the whole protection district rapidly.

The beneficial effect of the utility model is: 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, receive etching problem.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is a profile.

Fig. 2 is an outline drawing.

Fig. 3 is sprayer body figure.

Fig. 4 is nozzle figure.

The specific embodiment

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 the ripple pad on plane on the sprayer body be adjacent to several sealing ring of top board formation, outlet is provided with O RunddichtringO right angle groove, is connected sealing with nozzle.

Nozzle: the dimpling circular arc type, there are several to be uniformly distributed with and 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 to coniform, the directing flow medium reduces friction loss, several inclined holes that periphery is uniformly distributed with, 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.。
