VALVE OF HIGH PRESSURE

摘要

FIELD: machine building. ^ SUBSTANCE: high pressure valve consists of case. Movable and stationary gates are installed in the valve. A pipeline is positioned between the gates. At actuation of a pyro-drive the pipeline is shut off with the movable gate. The stationary gate is of wedge-like shape. The movable gate has a through slot for interconnection with the pipeline and stationary gate. A three-facet lug is made on each working surface of the slot. Ribs of the lug facets form triangle. Also, a slot is made along the pipeline on the facing it end of the stationary gate. The lugs of the slot of the stationary gate press the pipeline to the case. ^ EFFECT: valve of minimal dimension shutting off thick-wall metal high-pressure main with high degree of leak proofness. ^ 2 cl, 4 dwg
