AIR BLAST PROTECTION VALVE

摘要

PURPOSE: An air blast protective valve is provided to reduce non-axial stress from elastic elements and to reduce axial movement less than axial movement of a closed element. CONSTITUTION: An air blast protective valve comprises a closed element(15), multiple elastic elements(18), and multiple non-elastic coupling elements. The closed element is elastically supported inside a housing(9). The elastic elements have a first end part and a second end part. The first end part is attached to the surface of the housing. The non-elastic coupling elements convert axial movement of the closed element caused by air flow to axial movement of the elastic elements or reduced elements.
