Description
Technical field
The present invention relates to a kind of raindrop type layering sphere purge nozzle, the brute force that is applicable to compressed air, fan airflow purges, and belongs to industrial purge nozzle, specifically a kind of metallic nozzle of raindrop type layering sphere.
Background technology
Domestic purge nozzle only has the compressed air of employing to do source of the gas at present, is only suitable for the compressed air of low discharge, high pressure, and does not use the fan airflow of large flow, low-pressure to do the purge nozzle of source of the gas.
Summary of the invention
A kind of raindrop type layering sphere purge nozzle
the technical issues that need to address and goal of the invention are: the deficiency that overcomes background technology, provide a kind of compressed air of applicable low discharge, high pressure that both can use to do source of the gas, can use again the fan airflow of large flow, low-pressure to do source of the gas, can also guarantee that it purges distance and purging power and reach the raindrop type layering sphere purge nozzle of best simple and reasonable, jet-impingement that own wt is lighter simultaneously.
A kind of raindrop type layering sphere purge nozzle
design considerations be:core air stream is produced by Lavalle purge nozzle.Utilize the Lavalle principle in spraying technique, make to pass through nozzle Lavalle aditus laryngis by air compressor or the blower fan large flow-rate gas stream that enters air feed feeding pipe output, that there is certain pressure, produce supersonic speed, the gas of fan airflow is subject to the first half of high pressure flow nozzle, through after narrow larynx by latter half of effusion.This framework can make the speed of air-flow because the variation of spray sectional area changes, and makes air-flow from subsonic speed to velocity of sound, until accelerate to transonic speed.Transonic fluid is but no longer followed the principle of " little place, cross section flow velocity is large, and cross section general goal flow velocity is little " in the time of motion, but on the contrary, cross section is larger, and flow velocity is faster, is equivalent to the 7-8 of velocity of sound doubly, has so just produced huge thrust.This designs of nozzles can change kinetic energy into whole energy of compressed-air-storing effectively, and can not make air horizontal proliferation when by nozzle.Due to effective protection of protection laminar flow.Surrounding air can not make core air-flow slow down, and so just can reach best jet effect.The all right tissue turbulence air-flow of air-flow, has therefore reduced noise of air widely.
The present invention reaches goal of the invention by the following technical programs: the present invention relates to a kind of raindrop type layering sphere purge nozzle, be applicable to the powerful purging of compressed air or fan airflow, nozzle comprises main air chamber (1), main body (2), sphere nozzle segment I (3), sphere nozzle segment II (4), sphere nozzle segment III (5), sphere nozzle segment IV (6), sphere nozzle segment I (3), sphere nozzle segment II (4), in sphere nozzle segment III (5), there is respectively the raindrop type sphere air outlet (7) of varying number and size, the central outlets of sphere nozzle segment IV (6) is Lavalle structure air outlet (8), the main body that it is characterized in that described raindrop type layering sphere purge nozzle is that hollow is uncovered, on the faying face of multiple sphere nozzle segments, be along the circumferential direction equidistantly distributed with at least one raindrop type sphere air outlet.Described main air chamber (1) is the streamlined cavity being made up of curve, and in it, there is the section of being threaded in outside, and is connected with main body (2), air feed feeding pipe (9) screw threads for fastening.Described main body (2) inwall has the section of being threaded, and is threaded, is welded to connect with sphere nozzle segment I (3) with air compartment (2).On the front end faying face of described sphere nozzle segment I (3), be along the circumferential direction equidistantly distributed with at least one raindrop type sphere air outlet, be welded to connect with main body (2), sphere nozzle segment II (4).On the front end faying face of described sphere nozzle segment II (4), be along the circumferential direction equidistantly distributed with at least one raindrop type sphere air outlet, be welded to connect with sphere nozzle segment I (3), sphere nozzle segment III (5).On the front end faying face of described sphere nozzle segment III (5), be along the circumferential direction equidistantly distributed with at least one raindrop type sphere air outlet, be welded to connect with sphere nozzle segment II (4), sphere nozzle IV (6).The central outlets of described sphere nozzle segment IV (6) is the air outlet of Lavalle structure.
