Abstract

The invention discloses a contact sealing port structure for high-pressure delivery pipelines. The contact sealing port structure comprises an inner pipe, an outer sleeve and two pipe-end structures. The two pipe-end structures are connected with each other by the inner pipe, triangular annular ribs are respectively arranged at two ends of the inner pipe, triangular annular grooves are formed in the side surfaces of the ends of the pipe-end structures, the width of each triangular annular groove is larger than that of each triangular annular rib, rubber is arranged inside each triangular annular groove by means of injection molding, and the triangular annular ribs are fittingly abutted to the rubber in the triangular annular grooves, so that the inner pipe can be hermetically connected with the pipe-end structures, threads are arranged on the outside of each pipe-end structure, and the outer sleeve is connected with the two pipe-end structures in a threaded manner. The contact sealing port structure for the high-pressure delivery pipelines has the advantages that the two pipe-end structures are connected with each other by the outer sleeve, and the triangular annular ribs at the two ends of the inner pipe are abutted to the rubber in the triangular annular grooves, so that the two pipe-end structures are sealed from each other.

Description

technical field [0001] The invention relates to a contact sealing interface structure of a high-pressure transmission pipeline, which belongs to the technical field of high-pressure transmission petroleum pipelines. Background technique [0002] The sealing problem after the oil pipeline is docked is a very important problem. In the prior art, flange joints are often used for connection and sealing. The tensile force transmitted to the flange is also easy to cause damage to the flange, so the requirements for the flange are relatively high. At the same time, due to the long-term high stress, the flange and the bolts used to connect the flange will inevitably produce fatigue stress after a period of use, so the longer the use time, the easier it is to be damaged. [0003] At the same time, due to the high-pressure and high-speed transportation of oil pipelines, the sealing performance of pipelines under high-pressure environments is also a technical problem faced by the exis...
