Continuous pouring precision control device for multiple combustion chambers

Abstract

The invention provides a multiple-combustor continuous pouring dosage accurate control device. A blanking sleeve is positioned at the center of a pouring cylinder upper cover, the upper portion of the blanking sleeve is installed in a transition section of the pouring cylinder upper cover, and the lower portion of the blanking sleeve is positioned in a pouring tank. A receiver assembly is positioned below the blanking sleeve and connected with a rotary support through a connection rod in the receiver assembly. A supporting plate is fixed on the inner wall of a pouring tank body, and the rotary support is arranged on the upper surface of the supporting plate. A rotary air cylinder is fixed on the lower surface of the supporting plate through bolts, and the output shaft of the rotary air cylinder penetrates through the lower surface of the supporting plate. By means of accurate control, the multiple-combustor continuous pouring dosage accurate control device solves the problem that in the prior art, the quality range of a propulsive agent dripping after a rubber tube valve is closed is large and the dripping time of slurry is long, and effectively achieves fast pouring accurate control of the slurry in solid propellant loading industries.

Description

technical field [0001] The invention belongs to the technical field of solid rocket motors, and relates to a control device for weighing and pouring solid rocket motor propellants. Background technique [0002] The continuous pouring dose control process of multiple combustion chambers adopts the method of installing an explosion-proof electronic scale under the base of the combustion chamber, and controls the propellant pouring quality through mass weighing. After the expected pouring dose is reached, the feeding valve is closed to complete pouring. [0003] In the current process, the rubber hose valve is used as the feeding valve control device. After the operator closes the rubber hose valve, due to the strong adhesion of the propellant, part of the propellant will still stick to the lower end of the rubber hose valve body and continue to go downward. In the process of operation, in order to prevent dangerous accidents such as propellant explosion caused by mechanical fr...

AI Technical Summary

Problems solved by technology

However, the application of the hose valve has great fluctuations in the control of the pouring quality of the propellant. Due to the viscous fluid characteristics of the propellant itself, the mass of the propellant in the engine will still increase slowly after the hose valve is closed, and the increased quality cannot be accurately controlled. , there is still a certain gap in the requirements for the charging process that requires precise control of the propellant pouring quality
