Embodiment Construction

[0027] An electric start fuse type quick release valve, comprising a valve body main part 1, a pressure gauge 2, a safety valve 3, a plug cap 4, a bottle opening device 5, an inflation valve 6, a retaining spring 7, a protective sleeve 8, and a compression nut 9. Sealing ring 10, fusible plug 11, electrical connector 12, housing 13, valve core 14, output port 15, gas cylinder port 16, spring 17, O-ring 18, orifice 19, etc.

[0028] The spring 17 is assembled on the left end step shaft of the valve core 14, and then the corresponding O-ring is assembled in the sealing ring groove of the valve core, and the valve core 14 is assembled inside the upper casing 13 of the main part of the valve body 1 In the channel, the plug cap 4 is installed on the left side of the valve core 14 and the side of the spring 17. The plug cap 4 and the housing 13 are connected by internal threads, and the spring 17 is restrained. A certain pre-tightening force is applied to the spring 17 through the pl...

Abstract

The invention provides an electric starting fusing type quick release valve. The electric starting fusing type quick release valve comprises a valve body main part, a bottle opening device, an inflation valve, a valve element, an output connector and a throttling hole. The valve element arranged on the valve body main part is of a step type piston structure, the inside of a shell is divided into acavity A located in the right end of a valve element step and a cavity B located in the left end of the valve element step, and an output connector channel is closed through the piston end. The throttling hole formed in the valve element forms an airflow channel for the cavity A and the cavity B, and the pressure of the cavity A and the pressure of the cavity B are balanced. The bottle opening device comprises a fusible plug and an electric connector and is electrically connected with the fusible plug through the electric connector, direct current is conveyed to the fusible plug to reach setfusing energy, and after the fusible plug is loosened, the cavity B forms a deflation channel. The valve element is pushed from the end, with the large pressure, of the cavity A to move towards the end, with the small pressure, of the cavity B, the output connector is opened, and gas in a gas bottle connected with the inflation valve outputs a gas source to a device to be inflated to achieve gas supply. High popularization value is achieved.

Description

technical field [0001] The invention is an emergency gas cylinder valve product, belongs to the technical field of emergency lifesaving, and is specifically an electric start fuse type quick release valve. Background technique [0002] Aviation emergency inflatable airbags need to be equipped with an air source device for emergency inflation. The air source device is required to work and deflate for a short time after starting to inflate the emergency airbag. Therefore, the safety and reliability of the air source device are high. The core component of the device is the quick release valve, which can display pressure, charge and deflate, safely release pressure, seal internal gas, and release air in an emergency. [0003] The existing quick-release mechanism is an pyrotechnic starting structure, which has problems such as complex structure, difficult processing, high production safety requirements, and high cost. Contents of the invention [0004] The object of the presen...
