FIELD: fluid-pressure engineering.
SUBSTANCE: destructible diaphragm comprises disk secured over periphery. The disk has a thickening in the central part. The grooves are made over periphery of the thickening and are formed of split rings with straight line end sections that form a flexible radial cross-pieces in the peripheral section of the disk. The cross-pieces are distributed uniformly. The additional straight line grooves connect the ring grooves one to the other through the center of the disk. The diameter and thickness of the disk are determined form the equations proposed.
EFFECT: enhanced reliability.
