Abstract
The utility model relates to a silencing blowing nozzle with adjustable head rotation air quantity. In the utility model, the external of the outlet end of the blowing spout is provided with an intercept ball body which can rotate in a spherical support, and a steering apparatus can adjust the blowing angle according to different requirements of winter blowing and summer blowing; one blowing end of the blowing nozzle is especially provided with an adjusting valve which has simultaneously the functions of throttling, diffluentence and flow equalization, and the adjusting valve has low tendency to generate vortex flow; the blowing nozzle is communicated with a half-moon cavity in the intercept ball body by a small hole to form a resonance cavity to perform the silencing effect; a blowing nozzle body and a steering mechanism are snugly arranged in a static pressure box or a blowing pipeline, which is favorable for inner decorating coordination of a building, and an exposed part is similar to cats eyes, which has a finite decorative effect.
Description
The utility model relates to a kind of air-supply spout, belongs to the air conditioner accessory.
Modern large public building Air-conditioner design often adopts the outlet convergent can obtain the nozzle outlet air supply of big range, because winter, summer air-conditioning wind-warm syndrome degree difference, the nozzle outlet air supply angle needs to regulate within the specific limits, from available data, its rotary part is all in spout and air supply duct joint portion, because this type of jet size is bigger, its length is generally 1.6 to 2 times of bore, therefore be difficult for hiddenly after the installation, be unfavorable for the coordination of interior decoration.
The purpose of the utility model is to provide a kind of air-supply spout that can be loaded on snugly in plenum chamber or the air supply duct, and its wind direction can be regulated within the specific limits, and quantity-adjustable, has silencing function concurrently, has necessarily ornamental simultaneously.
The purpose of this utility model is achieved in that this intercept sphere available metal or engineering plastics are manufactured, and make the back and are combined into one with spout at intercept sphere coaxial with taper hole of the outside increase of spout taper hole small end.Intercept sphere is installed in the self-aligning spherical support, can rotate in the certain angle scope, and the self-aligning spherical support fixed pan is concordant with plenum chamber or air supply duct wall, thereby makes the spout body hidden in plenum chamber or air supply duct.Utilize direction-regulator to rotate the spout body by lever and change wind direction, direction-regulator is a mechanical device, but preferably utilizes the bellows technology to realize regulating automatically by means of the temperature difference of winter, summer air-conditioning wind.Bore some apertures at spout body taper hole inner surface certain position, air-supply passage is communicated with semilune cavity in the intercept sphere forms resonant cavity, and paste fabric, make spout have silencing function at the taper hole inner surface.Adorn leafy formula control valve at the big end of spout body, the characteristics of this valve are respectively to be loaded on the valve body successively with the moving vane of equal number and fixed blade, blade shape can be plane or curved surface, use the former in the time of in spout is loaded on plenum chamber, use the latter when being loaded in the ventilation shaft, this moment, forward face should be in face of airflow direction.Rotate moving vane and can change channel cross-section in order to regulate air output, all moving vanes are unified into one group with connecting rod, are once fixing after the debugging.This control valve plays throttling, shunting, water conservancy diversion and current-sharing simultaneously, and the tendency that produces eddy current is little, and noise is low.
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the structure chart of the adjustable noise reduction air-supply of head rotation air quantity spout.It is made up of spout body (1), self-aligning spherical support (5), control valve (7), leverage (8), direction-regulator (9), wallboard (10) etc.(2) are apertures among the figure, and (3) are the first quarter moon chambeies, and (4) are intercept spheres, and (6) are fabrics.
Fig. 2 is the section configuration of control valve (7), and (10) are moving vanes, and (12) are fixed blades.
When air-conditioning wind be hot blast when spout outwards blows, direction-regulator (9) elongation promotes spout body (1) by leverage (8) and makes it rotation counterclockwise self-aligning spherical support (5) in, wind direction is downward-sloping.Direction-regulator when sending cold wind (9) shortens, and this moment, spout body (1) clockwise direction rotated, air-flow in horizontal direction or the certain angle of facing upward blow out.Air-conditioning wind enters the spout body must be through control valve (7), and moving vane (11) and fixed blade (12) play shunting, water conservancy diversion, current-sharing effect, rotates moving vane (11) and can change aisle spare, plays throttling action.During air-flow process spout, the fabric of pasting on the spout body inwall (6) plays resistive sound deadening, can eliminate a part of high frequency noise, the resonant cavity of being made up of aperture (2) and first quarter moon chamber (3) plays the impedance complex sound deadening, make it to obtain suitable intrinsic neck rate by design, in order to eliminate in the part, low frequency noise.Spout body (1) is contained in the self-aligning spherical support (5), self-aligning spherical support (5), leverage (8), direction-regulator (9) are contained on the wallboard (10) together, wallboard (10) is contained on the aperture of plenum chamber or air supply duct reservation, have only spout body (1) head to expose like this, all the other each several parts are all hidden in plenum chamber or air supply duct.
Above-mentioned air-supply spout can be regulated wind direction on demand, the function that muffler is arranged, the tendency that produces eddy current when air-flow enters spout is little, can be loaded in plenum chamber or the air supply duct snugly, help the coordination of interior decoration, its structure is pressed the bionics principle design, intercept sphere analogy eyeball, self-aligning spherical support analogy eyelid, spout analogy pupil, adjusted device analogy extraocular muscle, the fabric of pasting can be chosen blackish green or black, intercept sphere is made milky or milk yellow, makes exposed parts as an opal, has stronger ornamental.
Claims (4)
1, a kind of adjustable noise reduction air-supply of head rotation air quantity spout of being made up of spout body (1), self-aligning spherical support (5), control valve (7), leverage (8), direction-regulator (9), wallboard (10), it is characterized in that: there is an intercept sphere (4) spout body (1) taper hole small end outside.
2, the noise reduction air-supply spout according to claim 1 defined is characterized in that: the one group of aperture (2) on spout body (1) the taper hole inner surface is communicated with the formation resonant cavity with first quarter moon chamber (3).
3, the noise reduction air-supply spout according to claim 1 defined is characterized in that: the big end of spout body (1) taper hole is equipped with the alternate successively control valve of forming with fixed blade (12) of moving vane (11) (7) that is equated by number.
4, the noise reduction air-supply spout according to claim 1 defined is characterized in that: have the device for regulating direction of being made up of direction-regulator (9) and leverage (8).
