    GAS FLOW REGULATING STRUCTURE For controlling the flow of a gas in a duct, a ring which is adapted to be situated in the duct surrounds a predetermined axis which passes through the center of the ring and which is normal to a plane containing the ring, this axis coinciding with the duct axis when the ring is situated in the duct. A plurality of overlapping throttling blades are pivotally carried by the ring and are adapted to be situated therewith in the duct. These blades define the side surface of a truncated cone and have upstream end defining the base of the cone and downstream ends defining the apex of the truncated cone as well as a throttling aperture through which the gas is adapted to flow. The cone defined by the throttling blades has an axis which coincides with the above axis. Thus, when the above ring and blades are situated in a duct it is possible to turn the overlapping throttling blades with respect to the ring so as to control the size of the throttling aperture which defines the apex of the truncated cone.

    专利说明:

    The invention relates to ventilation and can be used to control the gas flow in the pipes of ventilation units operating both for the inflow and exhaust of the contaminated 5 n < Th gas stream.
    A device for controlling the gas flow in the pipe ^, comprising a number of rotary reechnopodobnyh throttle plates attached th one end in the retaining ring and set to form a shell in the form of a truncated cone, the ring has a diameter equal to or less than the diameter of the pipe, and By arranging 15 laid perpendicular to the axis of the pipe C11 The disadvantage of this device is that the control range is limited.
    The purpose of the invention is the expansion of the range of regulation.
    This goal is achieved by the fact that in the device for regulating the gas flow in the pipe containing a series of rotary rack-like dividing plates 5 fixed at one end in the fixing ring and installed with the formation of a shell in the form of a truncated cone, the ring has a diameter equal to or smaller than the diameter of the pipe, and is perpendicular to the axis of the pipe, the rack-like plates are installed with mutual overlap and can be rotated relative to the locking ring.
    In this case, the plates are provided with loops attached to the fixing ring.

    In FIG. 1 schematically shows the proposed device, a top view; in FIG. 2 is a section AA in FIG. 1; in Fig .. 3 - throttling plate, General view.
    A device for regulating the gas flow in the pipe 1 contains a series of rotary rack-like throttling plates 2, fixed at one end in the fixing ring 3 and installed with the formation of a shell in the form of a truncated cone, while the ring 3 has a diameter D equal to or less than the diameter of the pipe 1, and is located perpendicular to the axis of the pipe 1. The rack-like plates 2 are mounted with mutual overlap and can be rotated around the locking ring 3, and the plates 2 are provided with loops 4 attached to the locking ring 3.
    The device operates as follows.
    The gas stream from the system either exhaust (not shown) or supply ventilation enters the pipe 1 and passes in the right amount through a series of throttling plates, t installed with the formation of a shell in the form of a truncated cone, the Number προχο · * ι of the supply gas through the pipe 1 is regulated by turning plates in the loops around the locking ring 3. This changes the bore of the pipe 1.
    Thus, the proposed implementation of the device allows you to adjust the amount of passing gas and its speed.
