Embodiment Construction

[0025] In order to enable those skilled in the art to better understand that the technical solutions of the present invention can be implemented, the present invention will be further described below in conjunction with specific examples, but the given examples are only used as illustrations of the present invention, not as limitations of the present invention.

[0026] Such as Figure 1-3 Shown is a universal rotary joint for aviation refueling equipment. The technical solution of the present invention is aimed at corrosion resistance and penetration resistance, and the workpiece can be effectively rotated by 360°. The relative angular rotation of the first workpiece 1 and the second workpiece 2 is realized through the universal rotary joint 15 without affecting the flow and loss of the intermediate internal fluid.

[0027] The first workpiece 1 part is composed of the first workpiece 1 and the first workpiece connecting plate 12, and the second workpiece 2 part can be compos...

Abstract

The invention relates to a universal rotary joint for aviation refueling equipment. The universal rotary joint comprises a universal rotary joint body, and a first workpiece and a second workpiece that are connected with two ends of the universal rotary joint body, wherein the first workpiece and the second workpiece are both formed by fixedly connecting workpiece bodies with connecting plates, two fastening screws and flat spring washers are arranged outside the universal rotary joint body, an outer lining and an inner lining which are through are arranged inside and outside the part, between the first workpiece and the second workpiece, of the universal rotary joint body, the outer lining and the inner lining are connected through balls and pin rollers and limit axial movement of the outer lining and the inner lining, and four sealing layers are arranged between the outer lining and the inner lining for sealing the outer lining and the inner lining. The universal rotary joint has the advantages that the first workpiece and the second workpiece can rotate at a relative angle through the universal rotary joint body, flowing and loss of fluid in the middle are not affected, corrosion resistance, permeation resistance, high efficiency and high stability are achieved, and the workpieces can effectively rotate by 360 degrees.

Description

technical field [0001] The invention belongs to the technical field of aviation ground refueling equipment, and in particular relates to a universal rotary joint for aviation refueling equipment. Background technique [0002] Airport refueling equipment is used to directly refuel or distribute aviation fuel to aircraft. At present, domestic aircraft fuel supply equipment is mainly fuel tankers and refueling trucks. After the plane lands, refueling trucks, air-conditioning vehicles, power supply vehicles, etc. move one after another. Go to relevant parts of the aircraft for energy supply and maintenance checks. Since the refueling vehicle itself is inflammable and explosive, and it is located on the ground, high temperature weather will affect the safety of the aircraft; in order to solve this problem, the fuel such as aviation oil is managed underground, and an aviation refueling equipment is provided Use universal swivel joints. Contents of the invention [0003] The ...
