    A tubular bellows element for fluids is provided which has concentric corrugations. The corrugations include flanks separated by spaces which narrow towards inner ends of the corrugations. The inner corrugation ends have a conical shape, and act as scales to increase the degree to which the ends of the bellows element can be moved with respect to each other. The inner ends also serve to provide an essentially smooth inner surface for the bellows element, minimizing both flow disturbance and the creation of turbulence.

    This invention relates to a valve. The sylphs are known, which contain the rays that are concentric with respect to the ocHli, the corrugations following each other, in which the inner corrugations are covered with a wire mesh or fabric to reveal the vortex-like vibrations inside them. This bellows is folded into fabrication and installation. The closest in technical essence to the present invention is a background force for gaseous or liquid media, containing a centrally located inlet and outlet nozzles relative to the axis relative to the axis and one after another corrugations, the annular gap between the edges of each outer corrugation in the zone of internal corrugations narrowed, and the BBj-TpenHHe corrugations themselves are made straight. In the well-known bellows, holes are made in the corrugations, which eliminates vortex formation, but only if it is static, since it can only perceive stretching, but not compression: limited herein and angular deformation. The purpose of the invention is to reduce the hydraulic resistance. The goal is achieved by the fact that in the bellows for gaseous or liquid media containing located between the inlet and outlet nozzles it is specific to the axis and the following is ONE after another, P | I1me the annular gap between kr 1ki of each external corrugation in the zone of internal. Corrugations is narrowed the internal lines themselves are straight, these corrugations are tilted in a uniform direction along the cone to the axis in the direction of the medium flow, and in the initial alignment the bends of the edge of each external corrugation are located in the same radial plane. An annular constriction, the diameter of which is smaller than the diameter of the inner corrugation, can be inserted in the inlet nozzle .: The drawing shows the proposed BELLOW. The bellows contains located between the inlet 1 and the outlet 2 nozzles concentrically relative to the axis and following one after the other corrugations. The annular gap 3 between the edges 4 and 5 of each outer corrugation 6 in the zone of the inner corrugations 7 is narrowed. Internal corrugations 7 are straight and are tilted uniformly along the cone to the axis in the direction of fluid flow (in the direction of arrow A). In the initial state, the bends 8 and 9 of the edges of each external corrugation 6 are located in the same radial plane. In the inlet nozzle 1, an annular constriction 10 is made, the diameter of which is smaller than the diameter of the inner corrugation 7. With this arrangement of the bellows, the bends 8 close the annular gap 3 from the flow, which contributes to a reduction in hydraulic resistance.

    1. BELLOW FOR GAS OR LIQUID MEDIA, comprising corrugations located between the inlet and outlet nozzles concentrically relative to the axis and successive one after another, the annular gap between the edges of each outer corrugation in the area of the inner corrugations being narrowed, and the inner corrugations themselves are made straight, revealing that that in order to reduce hydraulic resistance, the internal corrugations are inclined conically in the same direction in the direction of the medium flow, and in the initial state, the bends of the edges of each external corrugation are located in bottom of the radial plane. .

    2, Bellows by π. 1, about the temperature and part of the execution of a ring-narrowed. Diameter and fl with the fact that in the inlet pipe, which is smaller than the diameter of the inner corrugation.
    ; these corrugations are narrowed one after the other, and the annular gap between the edges of each external corrugation in the zone of internal corrugations is narrowed, and the internal corrugations5 are straight, these corrugations are inclined conically to the axis in the direction of flow of the medium, and in the initial state, the bends of the edges of each external corrugations are located in the same radial plane.
    In the inlet pipe can be you Λ is satisfied annular narrowing a diameter smaller than the diameter of the "inner corrugation.
    15 The drawing shows the proposed bellows.
    The bellows contains located between the inlet 1 and outlet 2 nozzles conically with respect to the axis and corrugations following one after another. The annular gap 3 between the edges 4 and 5 of each outer corrugation 6 in the area of the inner corrugations 7 is narrowed. The inner corrugations 7 are made straight and inclined uniformly — 25: conically to the axis in the direction of flow of the medium (in the direction of arrow A).
    In the initial state, the excesses 8 and 9 of the edge of each external corrugation 6 races are laid in one radial plane.
    30 In the inlet pipe 1, an annular narrowing 10 is made, the diameter of which is smaller than the diameter of the inner corrugation 7. With this design of the bellows, the bends 8 close the annular gap 3 from the 35 flow, which helps to reduce the hydraulic resistance.
