    The seal according to the invention comprises two sealing components of circular shape, and substantially concentric, namely: a static sealing component (1) and a dynamic sealing component (4), these two elements being connected to each other by an impermeable diaphragm (14). The component (4) comprises an envelope (5) forming an annular seat containing an elastically deformable annular support (7), against which is clamped a reaction ring (8). The invention makes it possible in particular to centre the support (7) on the reaction ring (8). <IMAGE>

    专利说明:

    The invention relates to a sealing device intended, in particular, to provide a seal in the upper and lower parts of the shutter containing a movable locking member inside the tubular body.
    The aim of the invention is to increase reliability and simplify the installation of seals.
    In FIG. 1 shows a partial section through a crane with a wing, in which a seal is mounted on the crane body; nafig. 2 is an axial half section of a seal according to the invention; in FIG. 3 is an embodiment of this seal.
    The seal to ensure tightness above and below the shutter, having a movable overlapping locking element 1 inside the tubular body 2, contains a round circular static sealing element 3, located between the flange 4 and the housing 2. The dynamic sealing element 5 is made of a round shape, contacts the sealing surface 6 with the sealing the surface of the locking element and is located concentrically relative to the static sealing element 3. Element 3 contains a helical spring 7 of an annular shape, often Normally the coated sealing sheath 8.

    Element 5 has an internal socket in which an elastically deformable annular beam 9 is installed in the shell 10. The annular beam 9 is made in the form of a coil spring of an annular shape. The sealing shell 11 of the dynamic sealing element 5 is formed by two radial parallel sides 12,13 and two axial sides 15, 14, one of which has a circular cross section and forms a sealing surface 6, and the other side 15 is perpendicular to the radial sides and is a continuation of the side 12 .
    With the beam 9 covered in the socket of the element 5, a feedback ring is mounted which is held axially by the radial sides 12, 13, and in the radial direction is held by the axial side 15.
    In the described example, the sealing elements 3 and 5 are made in the form of a single part, for example, a metal one, forming in its middle part an elastically deformable radial sealing membrane 16, which allows, on the one hand, to ensure the continuity of the seal between the two elements 3 and 5 and, on the other hand, play the role of an elastic element, providing the flexibility of self-centering of the element 5.
    The core of the membrane 16 has a round bend 17, giving it elastic radial deformability.
    The feedback ring 18 can be made of various materials and in this example it is made in the form of a spiral tape (Fig, 2).
    The seal assembly is placed (as shown in Fig. 1) in a radial annular cavity 19 formed between the side surface 20 of the valve body 2 and a flange 4 fixed to the specified side surface 20 by means of a clamping screw 21. The cavity 19 extends into the inner chamber 22 shutter, inside which the locking body can move. For example, the shutter (locking element) may be a lamb that can rotate inside the housing 2 and move axially at the end of the closing stroke. The annular cavity 19 has a rectangular cross-section, the width of which is equal to the width of the sealing shell 9 of the element 5. The upper side 24 and the bottom 25 of this cavity are formed by tiered bored surfaces - holes of the flange 4. An annular groove 26 is provided in the bottom of the cavity 19.
    In this annular groove 25, a static seal member is clamped. It should be noted that the installation of the latter is carried out at the time of installation of the flange 4, while the sealing pressure is achieved, for example, by clamping the flange 4 on the valve body 2.
    On the lower side surface 20 of the annular cavity, a circular recess 27 of rectangular cross section is made, in which the fold 17 of the sealing membrane 16 is located.
    The element 5, which serves to achieve dynamic sealing, has a large diameter slightly smaller than the inner diameter of the housing 2, but at the level of the average diameter of the sealing surface 28 of the locking member 1, so that this element 5 protrudes somewhat inside the inner chamber 22, a, in the closed position , the sealing surface 11 of the shell 9 and the beam are compressed between the feedback ring 18 and the surface 28 of the organ 1, i.e. self-centering of the element 5 around the surface 28 during closure is carried out while guaranteeing a uniform seal pressure at the level of the contacting surfaces of these two elements.
    The seal shown in FIG. 3 has a structure similar to the above structure.
    However, in this case, the beam formed by the annular spring 9 and the feedback ring 18 are placed in the shell 29, the outer surface of which is made to cover the internal shape of the sealing shell 11, while a set of these elements is tightly placed in this sealing shell 11. In addition, an annular volume enclosed between the two elements 3, 5, a floating retaining ring 30 is installed adjacent to the element 5, which can be used optionally when the seal operates at very high pressure ui.

    Claims (2)
    [1]
    Claim
    1. A seal to ensure tightness above and below the valve, having a movable overlapping locking member inside the tubular body, comprising a round circular static sealing element that is stationary between the flange and the casing, a round circular dynamic sealing element that contacts the sealing surface with the sealing surface of the locking member and is located concentric with respect to the static sealing element, an elastically deformable membrane tightly connecting the seal itelnye elements floating retaining ring located between the latter, primykayu-. 5 to the dynamic sealing element and located with a gap relative to the static sealing element, while the dynamic sealing element has an internal socket in which an elastically deformable annular beam is installed in the shell, characterized in that, in order to increase reliability and simplify installation, it is provided with a reverse ring connection installed in the seat of the dynamic sealing element with the coverage of the elastically deformable annular beam and pressed to the latter, while the opposite side The new walls of the nest for constant centering of the elastically deformable annular beam and the feedback ring are made radial.
    [2]
    2. Sealing by π. 1, more often because the elastically deformable annular beam and the feedback ring are covered by a common shell.
