    • 专利摘要:
    A double toric sealing ring for providing a seal between a casing and a butterfly member of a butterfly valve is formed with two helical springs each forming a torus and disposed concentrically. The helical spring forming the outer torus has a coil diameter greater than that of the coils of the spring forming the inner torus. Each spring is enclosed by a respective sheath. A metal annulus extending between the tori has its radially inner and outer peripheries bent around the respective sheathed tori. The radially extending portion of the annulus between these bent parts is formed with a bellows like groove concentric with the tori, to permit deformation of the sealing ring which in use is mounted in the butterfly valve so that the smaller diameter encased torus provides a seal between relatively stationary parts and the larger diameter encased torus provides a seal between the casing and the movable butterfly member when the latter is closed.

    专利说明:

    The invention Applies to ring-type seals.
    Known ring seals containing an elastic core in the form of a spiral spring, covered with a two-layer sheath jl.
    The disadvantage of these seals is the low reliability of the seal due to the lack of self-centering of the seal-10.
    In order to improve the reliability of sealing due to self-centering of the seal, the described seal is provided with an additional core laid concentrically, with the outer shell of the cores made C-shaped, covering them with their ends with a V-shaped notch in the middle part, and between the cores an opposing ring is installed adjacent to one of the cores.
    FIG. 1 shows a general view of the seal; in fig. 2 - seal, section 25
    The described metal ring seal consists of a core 1, an additional core 2, made in the form of a coil spring,
    covered with shells 3 and 4 and the outer shell tightness 5. Shell 5 is C-shaped, covers both cores with its edges and has a V-shaped notch 6 in the middle part. Opposing 7 is installed between the cores, adjacent to one of the cores.
    The described seal is installed, for example, in the valve body 8, pressed with a flange 9. The seal is pressed against the inclined surface of the valve 10 with a ring 7.

    Invention Formula
    A metal O-ring seal containing an elastic core in the form of a coil spring, covered with a two-layer shell, is characterized in that, in order to increase the reliability of the seal due to self-centering of the seal, it is provided with an additional core that is concentric, and the outer shell of the cores is C-shaped covering them with their ends with a V-shaped notch in the middle part, and between the core Q there is an opposing ring adjacent to one of the cores.
