TH166425B - Measuring device for the introduction of liquid additives In the main fluid stream - Google Patents

Abstract

Measuring device for the induction of liquid additives into the primary fluid stream. Flowing along the pipe This includes a pump (3) with a reciprocating differential piston for extracting additive (A) from container (2) and measuring the substance. The first (8) inlet for the main fluid flow which drives the pump, the second (9) inlet for the selection of additives and the outlet (10) for the mixtures of additives and the main fluid. It consists of the Venturi (11) which is installed in the pipe, the pump (3) connected in parallel with the Venturi (11), the first (8) inlet of the pump. Connected by The first (12) line with the inlet of Venturi while the outlet (10) of the pump is connected by the second line (13) to the venturi neck (11c) of the pump; Such device Includes path (E) for ventricular manipulation (11c) of venturi and path (G) sensitive to drop in pressure across the pump (3) for path control (E). ) Of venturi neck control to reduce the cylinder size section when pressure drop Across the pump increases and to increase the cylinder size set as the pressure drop across the pump decreases
