Embodiment Construction

[0005] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0006] Shown in accompanying drawing 1, the present invention mainly consists of nozzle a, lock nut, gasket a, screw, outer cover, glass tube, housing, pipe head, intubation tube, nozzle b, gasket b, nozzle c composition. Each interface component is connected by screw thread. When testing, first rotate the outer cover so that the glass tube is placed in the visible area, then the liquid to be detected enters the inside of the indicator through the nozzle b, and is discharged through the nozzle a. Since the inner diameter of the nozzle b is larger than that of the nozzle a, the liquid will accumulate inside the indicator, and the liquid level change can be visually seen through the glass tube. glass tube top. When the liquid level reaches the requirement, the flow state of the liquid can be observed through the glass tube. If there are bubb...

Abstract

The present invention discloses a liquid flowing indicator, which is mainly used for observing the flowing state of a liquid rocket propellant and checking whether the gas entrapment phenomenon exists. The liquid flowing indicator mainly comprises pipe connection mouths, a nut, a housing, a glass pipe, an inserting pipe, a pipe head, a gasket and other components, wherein a liquid propellant flows into the liquid flowing indicator through the inserting pipe and is accumulated to achieve a certain liquid level, and whether bubbles exist during the liquid propellant flowing process is observed through the glass pipe. The liquid flowing indicator of the present invention has characteristics of simple structure, reliable work, and effective liquid propellant flowing state detection.

Description

technical field [0001] The invention relates to a mechanical device, which is mainly used for detecting the flow state of liquid rocket propellant and belongs to the technical field of liquid rocket engine testing. Background technique [0002] The working principle of the liquid rocket engine is to use liquid propellant as the working medium, which is generally divided into two types: oxidizer and fuel. The two are used to organize combustion in the combustion chamber of the engine to form high-temperature gas with a certain pressure and discharge it at a high speed, so as to obtain the fuel required for rocket flight. thrust. Therefore, the work of the liquid rocket engine has very strict requirements on the quality of the liquid propellant, and air entrainment in the propellant is strictly prohibited, otherwise it will cause abnormal combustion of the propellant and cause damage to the engine. Therefore, it is necessary to have a special device for observing whether the ...
