SU1560856A1 - Flow regulator - Google Patents

Abstract

This invention relates to pipe fittings. The aim of the invention is to enhance the functionality of the device by allowing its use for large cross-section regulators. This is achieved by the fact that several identical regulating bodies-cylinders 3 are installed in case 1, each of which has radial through channels 8. The height of channel 8 is equal to 0.6 of the diameter of cylinder 3, the cross section of which is two symmetrical segments 9. Because the distance between the axes 4 and 5 of the cylinders 3 is equal to the height of the radial channel 8, then in the "Open" position the frontal projections of the segments 9 of the adjacent cylinders 3 coincide with each other, i.e. every third regulatory authority does not occupy the flow area of the channel of housing 1. 3 Il.

Description

FIG. 2

The invention relates to pipe fittings, namely, devices for controlling the flow of gas or liquid.

The aim of the invention is to enhance the functionality of the device by allowing its use for large cross-section regulators.

FIG. 1 shows the regulator in the “Open, longitudinal section” position; in fig. 2 - the same, in the “Closed” position; in fig. 3 - the controller in the position “Left view open.

The flow regulator consists of a housing 1, in which a regulating body 2 is installed, consisting of several identical cylinders 3, whose axis 4-6 of rotation is located in different cross sections of the device, and their forming cylindrical surfaces are interconnected. At the ends of the cylinders, for example, gears are installed, which are in constant engagement with each other. Axis 5 is connected to drive 7. In each cylinder 3 there are radial through channels 8, in the zone of which the cross section of cylinder 3 consists of two symmetrically located segments 9. Segments 9 of cylinder 3 are interconnected by stiffening ribs 10. The height of the radial through channel 8 is equal to 0.6 of the diameter of the cylinder 3, and the distance between the axes 4 and 5 of rotation in the direction along the flow is equal to the height of the radial channel 8.

The regulator works as follows.

In the “Open bore” position, it has a maximum value, since the frontal projections of the segments 9 of the adjacent | 3 cylinders coincide with each other. When rotating with the drive 7 axis

5 synchronous rotation receive all cylinders. The rotation angle, the flow area can be changed from the maximum value (Fig. 1) to complete closing.

(Fig. 2).

When the cylinders 3 are rotated 90 °, the chords of the segments 9 are on the same straight line without gaps between them. Regulator is closed. With the highest pressure drop corresponding to the complete overlap of the flow channel, both segments 9 connected by stiffening ribs 10 are involved in bending resistance (Fig. 2). And in the position corresponding to the full opening of the flow channel (Fig. 1), every third regulator does not occupy the flow area of the channel of the housing 1, and therefore the maximum possible flow area of the device increases.
