MD2713C2 - Liquid meter (variants) - Google Patents

Abstract

The invention relates to the measurement devices, in particular to the meters for measuring the quantity of liquids leaked through pipe-lines.The liquid meter, according to the first variant, contains a body with inlet and outlet pipes, in the flowing part of which, perpendicular to its axis, there is installed the impeller, kinematically joined with the axis of the indicator of the recording device. Novelty consists in that into the body, between the impeller and the recording device, there is fixed a sleeve, wherein onto the crank, rigidly joined with the axis of the impeller, it is mounted a double-ring satellite gear, one ring of which is in engagement with the central gear-wheel, fixed into the base of the sleeve from the impeller end, and the other ring is in engagement with the driven gear-wheel, kinematically joined with the axis of the indicator of the recording device.The liquid meter, according to the second variant, is characterized in that the impeller is fixed onto a cylindrical ring, onto the inner surface of which there is made an inclined guiding with rounded periphery, coupled with the annular groove, made onto the outer surface of the hub of the double-ring satellite gear, movably mounted onto the ball bearing. The inclined guiding may be made, for example, in the form of a closed helical prominence or in the form of at least three radially fixed and uniformly placed pins with spherical head.The liquid meter, according to the third variant, is characterized in that with the end face, oriented towards the recording device, of the impeller hub, made inclined, it is adjoined the end of the double-ring satellite gear, both rings of which are concentrically fixed thereon from the end of the recording device.
