Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] Such as Figure 1 to Figure 3 , a quick-release valve of the present invention, the quick-release valve is applied to a pressurized oxygen chamber vehicle on a plateau, and is used for adjusting the pressure in the pressurized oxygen chamber vehicle. The quick-release valve includes a valve core 2 and a valve seat 4. The valve core 2 is movably connected in the valve seat 4. The valve core 2 is provided with an air inlet 21 and an air outlet 22. The pressure difference between the inside and outside of the pressurized oxygen cabin vehicle Under the action, the valve core 2 is in contact with the valve seat 4, and the valve seat 4 seals the air inlet 21 on the valve core 2 at this moment. When the air pressure difference needs to be adjusted, move the spool 2 so that the spool 2 moves on the valve seat 4 and exposes the air inlet 21. At this time, the gas in the...

Abstract

The invention discloses a quick release valve. The quick release valve is applied to a plateau pressurized oxygen cabin vehicle and is used for adjusting the pressure in the pressurized oxygen cabin vehicle; the quick release valve comprises a valve element and a valve seat, an air inlet and an air outlet are formed in the valve element, the valve element is movably connected into the valve seat in a penetrating mode, and the air inlet is sealed through the valve seat; the valve element is moved, so that the valve element moves on the valve seat, the air inlet is exposed, air in the pressurized oxygen cabin vehicle enters from the air inlet and enters the outside of the pressurized oxygen cabin vehicle through the air outlet, and pressure adjustment in the pressurized oxygen cabin vehicle is achieved. The quick release valve is applied to a plateau pressurized oxygen cabin van, and pressure adjustment of the plateau pressurized oxygen cabin on the van is achieved through pushing and pulling of a handle on the quick release valve.

Description

Technical field: [0001] The invention relates to a quick release valve. Background technique: [0002] At present, there are few types of quick-release valves traditionally used on plateau type pressurized oxygen chamber vans, and the structure is fixed in a single form, which cannot meet the installation requirements of different parts of the pressurized oxygen chamber vehicle. Invention content: [0003] The invention provides a quick release valve, which can have two flexible installation modes, meets the use requirements of the quick release valve at different parts, and realizes the function of adjusting the pressure in the cabin. At the same time, the quick-release valve adopts a purely mechanical structure, which is pushed and pulled by the handles at both ends during operation, and the operation is easy, convenient, efficient and reliable. Therefore, the present invention not only has a novel structure, but also effectively solves the pressure regulation requireme...
