FIELD: treatment plants.

SUBSTANCE: invention relates to auxiliary devices for fluid supply facilities, which is preferably used in water treatment systems. Adapter (1) with a single channel for passage of liquid consists of upper part (2) equipped with a connecting element, with arranged therein section (9) of a single channel, and lower part (3), made with ascending (7) and descending (8) through longitudinal sections of a single channel, throttling device (10) and air gap (11). Section (9) of single channel of upper part (2) is formed at connection of connecting element of upper part (2) with lower part (3). Part of single channel consists of ascending (7) longitudinal section of channel and section (9) of single channel located in upper part (2), to ensure liquid passage to throttling devices (10) with equal speed. Ascending (7) longitudinal channel section and in liquid communication therewith section (9) of channel, located in upper part (2), have preferably an equal cross section. Connecting element of upper part (2) is made in form of grooves (4) with an arched shape, located inside upper part (2). Outer upper surface of lower part (3) has protrusion (5), shaped after recess (4), with a groove made along whole length of protrusion (5), repeating shape of protrusion (5) and confined by two side walls. Section (9) of single channel, located in upper part (2), is formed at connection of upper (2) and lower (3) parts due to internal free space of recess (4) of upper part (2) and groove of protrusion (5) of lower part (3) and has larger part of an arched shape.

EFFECT: reduced noise and vibration caused by flow of liquid through adapter.
