Abstract
Two flanged cylinders, one of which slides inside the other, are kept selectively in firm contact with each other by the engagement of elastic elements and their terminal booths with grips. The elastic elements and grips are fixed, respectively, on the outer perimeter of the inner cylinder and the outer perimeter of the outer cylinder. Engagement is maintained until the traction force applied to the two cylinders exceeds a predetermined value.
Claims6
A breakaway anti pollution safety valve in a fluid duct, the valve comprising two flanged cylinders, one of which slides inside the other, said cylinders being kept selectively in firm contact with each other by the engagement of a terminal tooth in a plurality of elastic elements with a plurality of grips, said elastic elements being peripherally distanced around and longitudinally extending from the outer perimeter of the inner cylinder and said grips being peripherally fixed on the outer perimeter of the outer cylinder, wherein said elastic elements have a calibrated radial elasticity so that the engagement is maintained until a traction force applied to the two cylinders exceeds a predetermined value which causes said elastic elements to bend outwardly.
A breakaway anti pollution safety valve comprising:
- opposed connection flanges, each of the connection flanges having a duct receiving surface;
- first and second flanged cylinders, each of the flanged cylinders connected to one of the connection flanges opposite the duct receiving surface, one of the flanged cylinders sliding inside the other flanged cylinder;
- a plurality of elastic elements attached to the flange of the inner cylinder and spaced from the outer perimeter of the inner cylinder, the elastic elements having a terminal tooth;
- an annular projection fixed on the outer perimeter of the outer cylinder;
- a gasket arranged between the inner perimeter of the outer cylinder and the outer perimeter of the inner cylinder;
- and
- a closable valve member mounted within each of the flanged cylinders;
- wherein the outer cylinder and the inner cylinder are kept in firm contact with each other by the outer cylinder being positioned between the outer perimeter of the inner cylinder and the elastic elements and the terminal tooth of the elastic elements engaging the annular projection on the outer perimeter of the outer cylinder.

- and
- a closable valve member mounted within each of the flanged cylinders;
- wherein the outer cylinder and the inner cylinder are kept in firm contact with each other by the outer cylinder being positioned between the outer perimeter of the inner cylinder and the elastic elements and the terminal tooth of the elastic elements engaging the annular groove on the outer perimeter of the outer cylinder.
