Embodiment Construction

[0022] The reusable electric explosion valve will be further described below in conjunction with the accompanying drawings.

[0023] This reusable electric explosion valve, such as figure 1 , a reusable electric explosion valve, including: a housing 1, a piston 2, a transmission mechanism 3, a valve ball 4, a sealing rubber ring 5, an igniter 6, a gasket 7, and a rubber ring 12. The piston 2 is placed at the upper end of the casing 1, the front end of the piston 2 is connected with the transmission mechanism 3, the tail end of the piston 2 is connected with the igniter 6 through glue, and there is an apron 12 between the piston 2 and the casing 1, which is used to prevent the igniter 6 from igniting produced impurities. The igniter 6 is mounted on the upper end of the casing 1 and sealed by a gasket 7 . The transmission mechanism 3 is installed and fixed in the housing 1 , and the transmission mechanism 3 is connected with the valve ball 4 .

Abstract

The invention discloses a reusable electric explosion valve. The reusable electric explosion valve comprises a shell, a valve ball enabling fluid to be output, a transmission mechanism controlling thevalve ball to rotate, a piston driving the electric explosion valve to be opened and an igniter pushing the piston to move are fixedly mounted in the shell from bottom to top, the valve ball is mounted in a fluid channel of the shell, the upper end of the valve ball is connected with the transmission mechanism, the upper end of the transmission mechanism is connected with the piston, and the igniter is arranged at the upper end of the piston and mounted on the upper portion of the shell. According to the reusable electric explosion valve, after the ignition device detonates, the internal structure of the electric explosion valve is not damaged, the electric explosion valve can be reused, meanwhile, the fluid passing through the electric explosion valve is not contaminated, and the reusable electric explosion valve has the beneficial effects of being simple in structure, good in economical efficiency, small in size, light in mass and the like.

Description

technical field [0001] The invention relates to an electric explosion valve, in particular to a reusable electric explosion valve, which belongs to the technical field of aerospace power devices. Background technique [0002] With the development of the aerospace field, higher requirements are put forward for the aerospace power system. Today, the aerospace power system is developing towards the trend of cleanliness, economy, light weight and miniaturization. In order to improve the reliability of the aerospace power system, there are high requirements for the precision inside the power system. However, most of the electric explosion valve devices used in the aerospace power system are disposable devices. Contamination of the medium, resulting in poor performance or failure of the aerospace power plant. At the same time, most of aerospace power systems are disposable devices and cannot be reused, resulting in poor economy of aerospace power systems. Contents of the inven...
