    1496463 Valves NELES OY 25 March 1976 [15 April 1975] 12128/76 Heading F2V In a butterfly valve having an elliptical disc 2 with a circular cylindrical outer edge surface disposed non-perpendicularly with the face of the disc, a U-sectioned seat packing ring 6 is disposed in a groove formed by an expansion of the flow passage in the body 1 and a support ring 5. The outer diameter of the ring 6 is smaller than that of the bottom of the groove, while the inner diameter of the ring is smaller than the largest diameter of the disc perpendicular to the axis of rotation 8 but larger than the smallest diameter of the disc along the axis of rotation. Thereby on closure of the valve the ring 6 is stretched in the direction of the largest diameter of the disc and at the same time is pulled in towards the disc in a direction perpendicular thereto.

    专利说明:

    This invention relates to a reinforcement. A valve is known with an elliptical body behind a porous organ mounted in the body flow channel on the rotary shaft and interacting with the peripheral one; a sealing surface with a metal sealing ring placed in the groove of the housing, the outer diameter of which is less than the diameter of the groove and the inner diameter is less than the width of the locking member in the direction perpendicular to the rotary shaft f 1J. However, the known construction does not provide a sufficiently reliable seal in aaKfsbiTOM position. The aim of the invention is to improve: reliability. The goal is achieved by the fact that the internal diameter of the sealing ring of the ring is greater than or equal to the width of the locking member in the direction along the turning shaft, the peripheral seal is w, and the surface is formed by a part of the cylindrical surface, the longitudinal axis of which is inclined to the plane of the locking member, and the sealing groove The ring is bounded by the surfaces of the bore made in the body and the end surface of the support ring mounted on the side of the flow channel. FIG. 1 shows the flap in the position close to closed, the cut; in fig. 2 - section A - A in FIG. 1: in FIG. 3 - damper in the closed position: on F1P. 4-section b-bna.fig. 3 in FIG. 5 is an enlarged view of the cross section of the sealing ring and the groove of the housing in which it is placed. The damper comprises a housing 1 with a passageway 2, in which the elliptical locking member 4 is mounted on the rotary shaft 3. The sealing surface of the locking member 4 is A-A part of the annular cylindrical surface, the longitudinal axis of which is not perpendicular. On the inner surface of the passageway 2, an annular groove 5 is made, in which a sealing ring 6 is placed, preferably made of metal and having a U-shaped cross section. One of the side walls of the ring 6 is clamped bnojfflbiM ring 7. The outer diameter of the sealing ring 6 is less than the diameter of the groove 5, and the inner diameter is less than the width of the locking member in the direction perpendicular to the rotary shaft, but greater than or equal to the width of the shaft in the direction of the rotary shaft. When an elliptical locking device 4 is installed in the closed position, it presses the sealing ring 6 from the unconsolidated position shown in FIG. 1, outward, towards the base of the groove 5, nfieJkne all, in the direction of the largest diameter of the locking member, simultaneously acting on the ring 6, tightly pressed to the edge of the locking member, primarily in the direction of the smallest diameter of the latter. Thus, when turning the closure member, the sealing ring follows the shape of its outer edge, and the shape of the ring is forcibly changed from the round to elliptical one; which ensures tight contact along the edge of the closure member. The duration of the wear movement of sealing views, which each other is minimized, which increases the rock compaction service. The technical and economic efficiency of the invention consists in increasing the reliability of the flap operation.
