PYROVALVE Russian patent published in 2023 - IPC F16K17/14 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to devices for gas and hydraulic systems. In the pyrovalve, the conical plug and the reciprocal conical seat are made in the form of two truncated cones located one behind the other along the length of the plug and body, respectively; on the surface of each plug cone there are three circular scallops 1.1-1.3 mm high and with a pitch of 2.0-2.2 mm between the tops of the scallops, the second plug cone along the rod and the corresponding seat in the body are made with larger dimensions than the first cone and seat, so that the ratio of the areas of the lateral surfaces of the second and first cones is 1.25-1.30.

EFFECT: simplified design, reduced cost of manufacture and increased reliability of the valve.
