Problems solved by technology

Due to the limitation of material properties, the surface roughness of the composite material after machining cannot reach high precision. As a result, when the rubber is vulcanized on the composite valve plate, the adhesion between the rubber and the composite material is poor, and it is easy to fall off, and the adhesive cannot firmly bond the rubber. Connected to the composite material, the product cannot achieve the intended function

Abstract

The invention provides a one-way valve and a manufacturing method of the one-way valve, and belongs to the technical field of composite material application. The one-way valve comprises a composite material valve seat and a composite material valve plate, and the composite material valve seat and the composite material valve plate are movably connected through a rotating shaft; an annular metal part is arranged in the edge area of the composite material valve plate, a rubber annular groove is formed in the metal part, an adhesive is coated in the rubber annular groove, rubber is vulcanized in the rubber annular groove coated with the adhesive, and the metal part and the rubber are glued through the adhesive. The rubber has good adhesion with metal parts on the composite material valve plate and is not easy to fall off, the adhesive can firmly adhere the rubber to the metal parts on the composite material valve plate, and the product can realize a predetermined function and is used for fuel oil reverse flow.

Description

technical field [0001] The present application relates to the technical field of composite material application, in particular to a one-way valve and a method for making the one-way valve. Background technique [0002] The one-way valve is installed on the inner rib web of the fuel tank. Its function is to prevent the reverse flow of fuel, and there is a certain reverse sealing requirement for the one-way valve. In the past, this kind of one-way valve usually adopts aluminum alloy material and vulcanized rubber sealing form to ensure the leakage. With the requirement of aircraft weight reduction, it is extremely urgent to carry out lightweight design for finished products. For products with simple structures such as one-way valves that cannot be reduced in structural design, weight reduction can only be achieved through the application of composite materials. [0003] In related technologies, the one-way valve is made of aluminum alloy. In order to ensure the sealing perfor...
