Abstract
The utility model discloses a spherical oiltank for a fuel engine. The oiltank shell is spherical. A measuring tube of a magnetic levitation type liquid-level sensor is arranged in a perpendicular center of the spherical shell vertical to the horizontal surface. The length of the measuring tube is similar to the inner diameter of the spherical shell. Each of the upper and lower ends of the measuring tube is provided with a circular hole. The circular hole in the upper end is less than that in the lower end. Each of the two circular holes is provided with a rolling steel ball in contact with the inner surface of the spherical shell. The steel ball with different qualities makes the measuring tube in the spherical shell to keep the gravity vertical. During the flight of the airship or the aircraft, the magnetic levitation type liquid-level sensor always keeps vertical. The oil level in the spherical shell does not change with the gradient of the spherical shell, which basically keeps horizontal. The fuel volume is exactly measured in a proper time. The utility model has the advantages of low manufacture cost, reliable security, easy removal of the sedimentary impurities and the like, which can be applied to other vehicles.

Background technique
The fuel tank of existing dirigible becomes square, and the float type liquid level sensor that has sounding pipe above the employing is measured oil level to obtain the in good time situation of change of fuel oil volume.Yet dirigible is in flight course, and it is stable that its hull attitude be difficult to keep, and usually produces certain angle tilt in pitch orientation and lift-over direction, and the variation at this tilt angle also is random, especially runs into aerial turbulent flow or prominent landscape condition.In this case, the square fuel tank that is fixed on the dirigible promptly changes with the attitude of dirigible, cause the oil level in the fuel tank to have greatly changed, fuel oil volume information in the dirigible fuel tank that obtain this moment has uncertainty, therefore dirigible is controlled personnel just possibly can't accurately judge the actual fuel oil volume situation of dirigible, thereby directly influences the success or failure of aerial mission.
The model utility content
The purpose of this utility model just is to provide a kind of fuel engine ball-type fuel tank, can the actual fuel oil situation of more accurate judgement to realize the personnel that control, carry out aerial mission better.
The technical solution of the utility model is: comprise fuel tank shell, be located at filler opening and oil outlet above the fuel tank shell, on filler opening, be provided with the oil sealing flap, it is characterized in that, described fuel tank shell is spherical, the sounding pipe of magnetic levitation type liquid level sensor is located at the vertical center vertical with horizontal plane in the spherical shell, the length of its sounding pipe is close with ball-type housing inner diameter, two ends up and down at sounding pipe respectively are provided with a circular hole, the circular hole of its upper end portion is less than the circular hole of underpart, the rolling steel ball that can contact with the ball-type shell inner surface respectively is housed in two circular holes, and the steel ball of different quality makes sounding pipe keep vertical state in the ball-type housing.
The sounding pipe of described magnetic levitation type liquid level sensor is provided with a float, described float is made up of oil outlet, oil strain chamber, mounting plate, oil cleaner screen and magnetic float, wherein annular oil strain Netcom is crossed in the annular filter oil pocket that mounting plate is fixed on upper surface sealing, lower surface opening, oil strain chamber thickness is close with magnetic float thickness, and its internal surface is by gluing together or closely cooperating and integral body of magnetic float formation; Oil strain chamber outer surface also be provided with one with the chamber in the oil outlet that communicates, link to each other with transport pipe.
Described oil sealing flap is disposed with the coaxial circular hole of different inner diameters from top to bottom on its lid, top circular hole internal diameter is smaller, in circular hole, be placed with rubber seal, hoodle and pressure spring, be provided with the screw thread that matches with filler opening on the inwall of the inner core below pressure spring, be provided with cambered surface wire netting identical with ball-type housing curvature and that coincide with the ball-type shell inner surface at interior tube bottom.
Described filler opening inwall upper end is provided with the screw thread that matches with the oil sealing flap.
Described oil outlet is the outlet of the signaling line of transport pipe and magnetic levitation type liquid level sensor, the length of transport pipe in the ball-type housing equates with ball-type housing internal diameter, also be provided with the transport pipe float of a plurality of spheroid shape resin materials at its outer surface, and in oil outlet, be filled with epoxy sealing glue.
The utility model is in dirigible or aircraft flight course, oil level in the ball-type housing does not change with the inclination of ball-type housing, pasta keeps level substantially, magnetic levitation type liquid level sensor remains vertical state, can record fuel oil volume accurately in good time, simultaneously, the float of magnetic levitation type liquid level sensor relies on deadweight to be positioned under the fuel tank pasta, makes transport pipe be full of clean product.In addition, it is low, safe and reliable to the utlity model has cost, and the impurity of precipitation is easy to advantages such as removal, and also can be applicable to other traffic tool.
