    A flow regulator for gaseous substances, particularly a flow regulator intended for air in air-conditioning and ventilation installations, for maintaining the volumetric flow of the gaseous substance at desired magnitude with sufficient accuracy when the differential pressure acting across the flow regulator (10) varies within given limits. The flow regulator (10) comprises an envelope (11) and a regulating member (12) turnably disposed in the flow passage confined by the envelope (11). The torque produced by the flow of gaseous substance on the regulating member (12) and on the other hand a counter-torque dependent on the position of the regulating member (12) cause the regulating member (12) turning in the flow passage to assume a position of equilibrium such that the requisite pressure drop is obtained for maintaining the volumetric flow rate at predetermined magnitude. The range of operation of the flow regulator (10) is changeable by regulating the size, dependent on the different angular positions of the regulating member (12), of the effective flow aperture (37) between the regulating member (12) and the flow passage. The effective size of the regulating member (12) is changeable in order to change the size of the effective flow aperture (37). The regulating member (12) is composed of parts (12a, 12b) placed to overlap and disposed to move so that the effective size of the regulating member (12) is changeable.

    the torque of the regulating element 3, and the scale 7 of the position of the carrier element 5.
    The device 1 is also equipped with a mechanism 8 for securing the carrier element 5 on the axis A in any position of this element relative to the axis A. The supporting element 5 is fixed in the housing
    9, the scale 7 of the position of the carrier element 5 is made on the housing 9, and the carrier element 5 is provided with its own scale
    10, corresponding to the scale 7 of the position of the carrier element 5 in the housing 9.
    The device 1 has a pointing tool 11 on the scale 7 of the position of the carrier element 5 on the body 9, made in the form of a ball, which is released around the circumferential head in a groove 12, which is made on the inside of the body f).
    The device is 1 cr. There is a wire on the pipe 13 and a rival rolling element 1A for setting the axis of rotation A to a horizontal position. In addition, to change the working range, there is an adjustment, and a knob 15. Device 1 also contains limiting elements 1B of pressure drop and a limiting pin 17.
    The device works as follows.
    When mounting the device 1 on the pipeline 13, the pointing device 1A installs the device so that axis A of the adjusting element 3 is in a horizontal position. The initial and final position of the regulating device, Lementch 3 of the device 1, when it is operated, depends on the volume flow rate with a constant pressure drop.
    When the device 1 operates on the regulating element 3, a torque is acting, the magnitude of which varies depending on the volume flow. A load 6, attached to a non-cyaf M epument with-5, which, in turn, is associated with the axis of rotation 4, creates a counter-torque.
    The angle of rotation between the initial and final positions of the regulating element 3 does not change at different volumetric flow rates, since the pressure differential remains constant. This is achieved by the fact that the regulating element 3 is two slightly curved plates overlapping each other.
    The operating range of the device 1 is controlled by changing the effective element 3 by the regulating element 3 between the case 2 and the regulating element 3, as well as by moving the load 6 on the supporting element 5.
    The carrier element 5 may have a load position scale 6 (not shown), on which the opposing torque is adjusted. On the housing 9 and the carrier element 5, a scale 7 is made, according to which the position of the carrier element 5 is determined during operation of the device 1. The tool 11 on the scale 7 of the carrier element is a ball moving around the circumference in the groove 12 on the inside of the case 9.
    The device 1 can be mounted on the pipe 13 in any direction, and the housing 9 can be located on either side of the pipe 13. This is achieved by the fact that the carrier element 5 can be set to the desired angle in opposite directions and fixed by the mechanism 8 on the axis four.
    The value of the flow rate setpoint of the device 1 can be controlled from wide limits of the volume flow rate, for example, a speed of 2-8 m / s, the device 1 is working without any change in the pressure value. The device may also operate at a lower pressure drop, for example, about 20 Pa. The range of operation of the device is 20-200 Pa.
    The working range of the device can be changed by turning the adjustment knob I, as a result of which rotation n :. stina regulatory
