FIELD: mechanical engineering, namely, preventive valves, possible use for preventing destruction of working vessels due to excessive pressure. ^ SUBSTANCE: preventive device with bursting membrane contains body 1 with coaxial input and output apertures, compression spring 7 (corrugated pipe), recess 9, insert 10 with liquid spray diffusers 11. Bursting membrane 3 is held on output aperture. Destroying element is made in form of a drill with rigidly mounted propeller 6. the drill is mounted on rod 5, positioned in an insert with possible turning. ^ EFFECT: lowered scattering of preventive device activation pressure value, meaning increased reliability of device activation. ^ 1 cl, 1 dwg |
