Problems solved by technology

On the other hand, this arrangement is not only relatively large in size, but also has the disadvantage that the structure for fixing the valve body to the manifold is located between the manifold and the seat of the corresponding opening / closing element and is a relatively deep cavity, A small amount of product can become trapped in it and it is difficult to remove this trapped product by flushing the manifold

Embodiment Construction

[0021] The figures show an example of an embodiment of a valve assembly according to the invention designed for use in a device for metering liquid products for the treatment and dyeing of fabrics. It will be appreciated that the valve assembly can also be advantageously applied to installations for metering different liquid products, for example in the chemical and cosmetic industry, in the paint industry, etc.

[0022] The valve assembly generally designated with reference numeral 1 is pre-set in a known manner, ie connected at the inlet to a plurality of storage units for liquid products which are usually fed to the respective Assign lines to assign to the equipment used. A measuring device is operatively associated to the distribution line, usually consisting of a flow meter of conventional type, which in turn is connected to an electronic processing and control unit controlling the operation of the valve assembly 1 .

[0023] In general, the valve assembly 1 comprises a ...

Abstract

A valved assembly (1) for plants for metering liquid products such as chemicals and auxiliary substances for dyeing fabrics and the like that are to be fed individually to a line for metered distribution to equipment, said valved assembly comprising a tubular manifold (2) equipped with a plurality of inlets (11) and a corresponding plurality of automatically controlled shutoff valves (3). The shutoff valves (3) are arranged in opposed pairs according to a V configuration with portions (9) of its valve bodies (4,9) integrated in a single piece with the manifold (2).

Description

technical field [0001] The present invention relates generally to devices for metering liquid products such as chemical and auxiliary substances, dyes, more specifically dyes for dyeing fabrics in the textile sector, in industries such as chemistry, pharmacy and cosmetics. Background technique [0002] The metering device to which the invention relates generally comprises a set of storage units for the different liquid products to be metered, and a distribution line for feeding the liquids individually to the devices used, the liquids being metered by volume or by weight. One or more valve assemblies are disposed between the storage unit and the distribution line, each valve assembly comprising a tubular manifold provided with a plurality of inlets connected to each storage unit and a corresponding plurality of shut-off valves, these Shutoff valves are automatically controlled to alternately open and close communication between the respective inlets and the manifold. The sh...
