Problems solved by technology

However, due to the fact that the current launch device needs to launch farther and farther, and with the increase of the range, the air pressure of the air storage tank is also increasing. When the air pressure of the air storage tank is greater than 10Mpa, the ordinary solenoid valve often The control is not sensitive, and sometimes it cannot be opened normally, which greatly affects the launch control of the launch device

Abstract

The invention relates to the technical field of unmanned aerial vehicles, in particular to a piston type multi-stage high-pressure gas switch. The piston type multi-stage high-pressure gas switch comprises a valve body, a valve element arranged in the valve body in a matched and sliding mode and a valve cover fixedly arranged above the valve body, the valve element is in sealing fit with the inner wall of the valve body, and an upper valve cavity is formed in the upper end of the valve element; and the valve cover is connected with a multi-stage gas control switch which communicates with the upper valve cavity and controls the upper valve cavity to release pressure. During use, the launching control precision of a control valve to a launching device is improved through the multi-stage gas control switch, when the gas pressure in a gas storage tank reaches 20-25 MPa, the piston type multi-stage high-pressure gas switch can quickly and accurately control communication and separation of a gas storage cylinder and a launching cylinder, instant opening is achieved, the response speed is high, the piston type multi-stage high-pressure gas switch can effectively control launching of a fire extinguishing bomb, and launching control of the launching device is greatly improved.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing bomb launching devices, in particular to a piston-type multi-stage high-pressure gas switch. Background technique [0002] When the present fire extinguishing bomb launching device is launched, the air storage tank is filled with high-pressure cold air. When the pressure in the air storage tank reaches a preset value, the gas storage tank is stopped to be inflated. The gas in the air storage tank enters the control valve through the air inlet, and enters the launching tube from the air outlet, so that high pressure is formed in the launching tube, and the fire extinguishing bomb is ejected from the launching tube under the push of high-pressure cold air, and the fire extinguishing bomb takes off. However, the current launching device needs to launch farther and farther, and with the increase of the range, the air pressure of the air storage tank is also increasing. When the air pressure...
