FIELD: mechanics.
SUBSTANCE: invention relates to sealing devices of sampling action, using pressure of sealed working medium, and is provided for usage in pipelines at overlapping of stream of working medium. Sealing of valve contains mobile lengthwise the axis sluice with internal tapered sealing surface and collar. Collar is implemented in the form of cylindrical shell made of elasticity tester and is conjugated with sealing surface. Envelope is fixed by clamping sleeve in holder of seat. Taper angle of sealing surface is 60°. Internal sleeve of holder is implemented with ability of value regulation of prestrain of collar by sluice. On top end of sleeve it is implemented industrial visor.
EFFECT: invention is directed to durability increase of sealing and to cost cutting of its manufacturing.
