Abstract
The utility model relates to an adjustable universal spherical ventilation spray nozzle device comprising a spray nozzle rotating shaft, a valve, a baffle ring, a spherical swivel, a spacing stop block and a mounting flange, wherein the baffle ring adopts an open-type structure; an open slot is formed in the middle of the baffle ring; a valve shaft is arranged on the shaft and is inserted into the open slot of the baffle ring; the valve is connected with the spray nozzle rotating shaft through a small shaft; the valve and the spray nozzle rotating shaft are mounted in the spherical swivel; the upper half part of the baffle ring is semicircular; the lower half part of the baffle ring is a circular arc of which the radius becomes larger and larger; the spacing stop block spaces the axial movement of the spray nozzle rotating shaft in the spherical swivel, so as to avoid axial thrust on the baffle ring during the operation of the spray nozzle rotating shaft, and further ensure the assembly reliability and the working safety of the baffle ring; and as the lower half part of the baffle ring is the circular arc of which the radius becomes larger and larger, after being mounted, the baffle ring can be released and propped automatically with a low probability of falling out, which ensures tighter assembly. The adjustable universal spherical ventilation spray nozzle device has the advantages that the structure is simple; the mounting is convenient; the property is stable, safe and reliable; and the occupied area is small.
Description
Technical field
The utility model belongs to the draft equipment technical field, relates to the spray nozzle device in the aircraft ventilation system, is specifically related to a kind of adjustable universal spherical ventilation spray nozzle device.
Background technology
The ventilation nozzle is the a/c system accessory equipment of aircraft, is used for ventilating to aircraft cockpit.At aircraft cockpit, the left side ram intake directly is connected with two ventilation nozzles of vertical collimator dash board and arranged on left and right sides, is used for ventilating to the front-row occupant head, and vent air flow and direction all can be used ventilation nozzle free adjustment.This type of scalable ventilation spray nozzle device belongs to the equipment of frequent operation, and baffle ring comes off when aviator's flight operation easily in the ventilation nozzle of prior art, and appearance can not be regulated the situation of ventilation, influences aviator's health and safety.
Summary of the invention
For overcoming the deficiency of prior art, the utility model provides a kind of adjustable universal spherical ventilation spray nozzle device, through reinforcement the spacing of nozzle rotating shaft is fixed, and makes firm, the stable performance of ventilation spray nozzle device assembling.
The adjustable universal spherical ventilation spray nozzle device that the utility model provides comprises nozzle rotating shaft, valve, baffle ring, spherical rotary head, mounting flange.Baffle ring is the opened type structure, and the centre of baffle ring is provided with open slot, and valve is provided with curtain shaft, and curtain shaft inserts in the open slot of baffle ring.Valve is connected with the nozzle rotating shaft through little axle, and the termination of nozzle rotating shaft is equipped with positive stop.
Positive stop is a loop configuration, and the positive stop that is used for other spacing structure of nozzle rotating shaft also is the protection domain of the utility model.Positive stop is installed in the nozzle rotating shaft through rivet, and block and nozzle rotating shaft are connected as a single entity.The first half of baffle ring is a semicircular body, and the latter half is that radius is gradually opened increase formula circular arc body.
Because the annular stop block has been installed in nozzle rotating shaft termination, has limited nozzle rotating shaft moving axially in spherical rotary head, avoid during the manipulating nozzles rotating shaft baffle ring is produced axial thrust, guaranteed the assembly reliability and the safety in utilization of ventilation spray nozzle device.Because the latter half of baffle ring is that radius is gradually opened increase formula circular arc body structure, the size of baffle ring is bigger than the size of spherical rotary head inside groove, the artificial inside groove of packing into that is out of shape during assembling, and the back baffle ring of packing into is decontroled stretching automatically, and difficult drop-off makes assembling more tight.The utility model is through the positive stop in the rotary nozzle rotating shaft; Realize that the air draft amount is from zero adjusting to maximum unlatching scope; Through rotating the direction that spherical rotary head can the regulated at will vent air; Can adjustable universal spherical ventilation spray nozzle device be installed in the various equipment that need to install the ventilation nozzle through exterior mounting flange, Applicable scope is extensive.The utility model is simple in structure, easy for installation, stable performance, safe and reliable, occupy little space.
