Abstract

The invention provides a pumped fuel swing device capable of bearing high pressure. The pumped fuel swing device comprises force transmission ring forks, a gimbal ring, an S-shaped reinforced corrugated pipe and a guide cylinder. The two force transmission ring forks are connected to the inlet end and the outlet end of the S-shaped reinforced corrugated pipe correspondingly, and each force transmission ring fork comprises a force transmission ring and two force transmission arms symmetrically connected to the two sides of the corresponding force transmission ring. The gimbal ring is of a ring-shaped structure and is uniformly provided with installation holes in the radial direction. A pin shaft is fixedly connected with the force transmission arms, joint bearings are installed in the installation holes of the gimbal ring, and the gimbal ring is hinged to the pin shaft through the joint bearings so that the force transmission ring forks can rotate relative to the gimbal ring. The forcetransmission rings are fixedly connected with the S-shaped reinforced corrugated pipe. The S-shaped reinforced corrugated pipe is arranged in the gimbal ring. The guide cylinder used for sorting the flow field directions is fixedly connected with the force transmission ring fork at the inlet end and is arranged in the S-shaped reinforced corrugated pipe. The fuel swing device capable of bearing the high pressure can meet the two-way swing requirement of a high-pressure fuel line of a liquid-propellant rocket engine, and a high-pressure medium is transported while good displacement compensationcapability is guaranteed in the engine swing process.

Description

technical field [0001] The invention belongs to the field of liquid rocket engine manufacturing, and can be used for pipeline deformation compensation that needs to swing under high-pressure conditions in other technical fields. Background technique [0002] The fuel swing device after the high-pressure pump is a deformation compensator for high-pressure pipelines, which belongs to the field of metal expansion joints. Metal expansion joints can realize the pressure-bearing function of pipelines and compensate for pipeline deformation during periodic swings. Petrochemical, electric power, automobile and shipbuilding and other industries have a wide range of applications. [0003] The standard JB-T 6171-2013 mentions that the angular universal expansion joint has the function of absorbing angular displacement in any plane and can withstand internal pressure. It is composed of bellows, pin shafts, hinge plates, universal rings and vertical plates. The corrugated pipe used in t...
