Sealing device

Abstract

The invention provides a sealing device consisting of a valve (1) movable along this axis XX', comprising the edge (4) of an orifice (9) at the end of a cylindrical conduit (6) with axis XX', in which a fluid (8) flows, and a valve (1) movable along this axis XX', having a head (3) of a diameter larger than that of the conduit (6) and which, by bearing against said edge (4) of the orifice (9), which thus constitutes the seat of the valve (1), is capable of closing the latter, said valve (1) and said seat (4) of the orifice (9) forming part of the sealing device, and such that: the bearing surfaces of the seat (4) on the one hand and of the head (3) of the valve (1) against this seat (4) on the other hand are both conical with respect to the axis XX', and form between them an angle (α) greater than 0° and less than or equal to 15°, the orifice (9) The end of the conduit (6) is the outlet of the fluid (8) which flows through the conduit (6) towards the head (3) of the valve (1), Figure of the abstract: Fig. 1
