Abstract
A fuel duct leading-out device is composed of a connecting piece (3) and a duct (2), wherein the connecting piece (3) is covered on the duct (2). The fuel duct leading-out device is characterized in that the lower end face of the duct (2) is a chamfer with a certain angle alpha which is more than 0 degree and less than or equal to 45 degree. The fuel duct leading-out device not only discharges gas or liquid in the device smoothly, but also avoids pollutions of device surface, simultaneously has the advantages of simple in structure and easy to realize.
Description
Technical field:
The utility model relates to the design of ejector, and a kind of fuel duct ejector is provided especially.
Background technology:
At present, because the work characteristics of aircraft system need be discharged to the aircraft outside with gas in the aircraft system or liquid.Yet, in existing technology, because the kinematic velocity of aircraft is very fast, make head-on air-flow hinder the discharge of gas in the system in the motion process or liquid, yet, even gas in the system or liquid can successfully be discharged to the outside of equipment, but owing to equipment is among the high-revolving motion, so gas or liquid that airflow flowing is easy to discharge blow to aircraft surfaces, pollute body.
Therefore, people expect to obtain a kind of inside that gas or liquid can be discharged aircraft always, also do not pollute the fuel duct ejector of aircraft surfaces simultaneously.
The utility model content:
The purpose of this utility model provides a kind of fuel duct ejector of new structure, discharges problem difficult and the pollution aircraft surfaces with gas or liquid in the aircraft system that solves high-speed motion.
In order to solve above technical matters, the utility model provides a kind of fuel duct ejector, described ejector is made of attaching parts 3 and conduit 2, wherein, attaching parts 3 is enclosed within the outside of conduit 2, it is characterized in that: the lower end surface of described conduit 2 is the certain angle α that cuts sth. askew, and 0 °＜α≤45 °.
The lower end surface of described conduit 2 is the design of certain angle α of cutting sth. askew, and 0 °＜α≤45 °; When being to reduce to move by the design of cutting sth. askew, its purpose discharges gas or the suffered gas pressure intensity that makes progress of liquid, thereby reach suffered downward gravity of discharge gas or liquid and pressure sum greater than the gaseous tension that makes progress, make the gas or the liquid that need to discharge successfully to discharge; Wherein, the size of mis-cut angle α is to come design-calculated according to the running velocity of aircraft and the curvature of aircraft surfaces.Simultaneously, before long part was placed in the end face of cutting sth. askew of conduit 2 lower ends, after short part was placed in, in the time of can stopping airplane motion effectively, air-flow avoided polluting body with the surface that the gas of discharging or liquid blow to aircraft.
The bottom of described attaching parts 3 links to each other with the body 1 that needs carry out gas or liquid derivation, its objective is in order to make attaching parts 3 be placed in the inside of body 1, resistance during with the minimizing airplane motion, simultaneously can reduce the wearing and tearing of external environment condition to attaching parts 3, thereby increased the service life of attaching parts 3, wherein attaching parts 3 and the type of attachment of equipment 1 can be that nut is connected or is welded to connect.
Advantage of the present utility model is: the gas or the liquid of internal body successfully can be discharged, also can avoid the pollution of body surface, simultaneously, the exporter in the utility model is simple in structure, is easy to realize.
Description of drawings:
Fig. 1 is the lateral plan of fuel duct ejector;
The specific embodiment:
The structure of fuel duct ejector as shown in Figure 1, be made of conduit 2 and attaching parts 3, wherein attaching parts 3 is enclosed within the outside of conduit 2, and the lower end design angle of conduit 2 is 10 ° the end face of cutting sth. askew, and relatively long part is preceding in the end face of cutting sth. askew of conduit 2 lower ends, relatively the short part of end after; Whole ejector is linked together by attaching parts 3 and the form of the body 1 that need carry out the derivation of gas or liquid by welding.
The structure of fuel duct ejector as shown in Figure 1, be made of conduit 2 and attaching parts 3, wherein attaching parts 3 is enclosed within the outside of conduit 2, and it is 30 ° the end face of cutting sth. askew that the lower end of conduit 2 is designed to angle, and relatively long part is preceding in the end face of cutting sth. askew of conduit 2 lower ends, relatively the short part of end after; Whole ejector is linked together by attaching parts 3 and the form of the body 1 that need carry out the derivation of gas or liquid by nut.
The structure of fuel duct ejector as shown in Figure 1, be made of conduit 2 and attaching parts 3, wherein attaching parts 3 is enclosed within the outside of conduit 2, and it is 45 ° the end face of cutting sth. askew that the lower end of conduit 2 is designed to angle, and relatively long part is preceding in the end face of cutting sth. askew of conduit 2 lower ends, relatively the short part of end after; Whole ejector is linked together by attaching parts 3 and the form of the body 1 that need carry out the derivation of gas or liquid by welding.
