FIELD: machine building.
SUBSTANCE: regulator comprises a valve body having an inlet and an outlet opening allowing the fluid to flow therethrough, support plate located inside the lid and connected to the valve body, as well as the first and second diaphragms. Each diaphragm has a corrugated profile and is located in a layered configuration. Corrugated profiles have a sawtooth structure formed by a plurality of linear portions forming sharp edges or bending points. Diaphragms are functionally connected to the support plate, and each of the diaphragms is clamped between the valve body and the lid near the outer edge of the diaphragm.
EFFECT: increased service life of the diaphragm.
