Embodiment Construction

[0039] The invention discloses a swing hose to prolong the service life of the swing hose.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041] see Figure 1-Figure 8 . The invention discloses a swing hose, which includes an inlet flange 1 , an outlet flange 2 and an outer bellows 3 .

[0042] Such as figure 1 and 3 As shown, one end of the outer bellows 3 is connected to the inlet flange 1 , and the other end of the outer bellows 3 is connected to the outlet flange 2 .

[0043] Preferably, the out...

Abstract

The invention discloses a swing hose. The swing hose comprises an inlet flange, an outlet flange and an outer corrugated pipe. According to the scheme, bending deformation of the swing hose within a certain angle is compensated through telescopic deformation of the outer corrugated pipe, so that the service life of the swing hose is prolonged, a stable support assembly can play a role in limitingtelescopic movement of the outer corrugated pipe, and it is avoided that the outer corrugated pipe and an inner corrugated pipe extend excessively to affect propellant conveying.

Description

technical field [0001] The invention relates to the technical fields of aerospace and petrochemical industry, in particular to a swing hose. Background technique [0002] The swing hose is an important element of the propellant supply system in the liquid rocket engine, and its function is to ensure the normal and reliable delivery of the propellant. [0003] The oscillating hose in the prior art will inevitably sway along with the engine during use, and the oscillating hose cannot perform length compensation through bending deformation, resulting in shortened service life of the oscillating hose. [0004] Therefore, how to prolong the service life of the swing hose has become a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0005] In view of this, the present invention provides a swing hose to prolong the service life of the swing hose. [0006] To achieve the above object, the present invention provides the following te...
