Description
Technical Field
The utility model relates to a no flaring internal diameter rolling pipeline connects belongs to aviation hydraulic pressure pipe connection technical field.
Background
The flaring-free connecting technology is one of important connecting technologies of an airplane hydraulic pipeline system, has high sealing performance and connecting strength, can meet the requirement of airplane safety and reliability, and is more and more widely applied to the field of aviation. The hydraulic pipeline is the part with highest working pressure and the most strict requirement on reliability in pipelines of the airplane, and the technical level of the pipeline system of the airplane is intensively embodied in the hydraulic pipeline system. For a hydraulic system, under the same power condition, the higher the working pressure is, the smaller the required bottom area of the action cylinder and the oil pump piston is, the smaller the required pipeline flow is, and therefore, the overall size and weight of the hydraulic system can be correspondingly reduced and lightened, and the lower medium flow rate also reduces the power loss flowing in the pipeline. Therefore, there is a continuing need to investigate the objective need for the development of higher operating pressure hydraulic systems and their standard parts in the aerospace industry. The civil aircraft has found that the pipeline fails, such as the defect of partial sealing failure and the defect of partial poor torsion resistance.
SUMMERY OF THE UTILITY MODEL
Therefore, an object of the present invention is to provide a novel flareless inside diameter rolled pipe joint which can overcome the above-mentioned drawbacks.
In order to realize above-mentioned purpose, the utility model discloses a no flaring internal diameter rolled pipe way connects, including inside wall and lateral wall be provided with annular arch on the lateral wall and be located the protruding one side of annular be used for with the interior conical surface matched with sealing region of outer connecting piece, sealing region is including smooth connection's first conical surface, arcwall face and second conical surface in proper order be provided with annular rolled groove and profile of tooth annular on the inside wall, the rolled groove is seted up in the one side that is close to sealing region, the profile of tooth annular is close to the rolled groove setting.
The rolling grooves are arranged in parallel at intervals, and the tooth-shaped ring grooves are arranged close to the rolling groove at the innermost side.
The tooth-shaped ring grooves comprise a plurality of ring grooves which are arranged in parallel at intervals, and teeth are formed between the adjacent ring grooves.
The teeth include an arcuate tip.
Still be provided with bellied strengthening rib on the inside wall, the strengthening rib extends along the axial, the strengthening rib is located the one side of keeping away from the rolling groove of profile of tooth annular.
A plurality of the strengthening rib forms a set of, and the multiunit strengthening rib equipartition is in the circumference of inside wall.
Four groups of reinforcing ribs are arranged.
Adopt above-mentioned technical scheme, the utility model discloses a no flaring internal diameter rolling pipeline connects, compare with prior art, has following beneficial effect:
1. tooth-shaped ring grooves are added on the inner sides of the rolling grooves, so that the number of sealing surfaces after spinning is increased, and multiple sealing is guaranteed;
