DOSING SYSTEM FOR DOSING OF A LIQUID ADDITIVE INTO A PRESSURIZED WATER SUPPLY LINE

摘要

The invention relates to a dosing systern for dosing of a liquid additive into a pressurized water supply line. In order to use the dosing the systern for dosing of a spontaneously de-gassing liquid additive, a liquid additive reservoir (20) is po­ sitioned within an additive supply line (11) upstream of a feed pump (18), the liquid additive reservoir (20) is provided with a gas exhaust valve (21), and in operation, liquid additive is delivered from a liquid additive supply (6) to the liq­ uid additive reservoir (20) filling the liquid additive reservoir (20) up to a certain level enabling de-gassing of the liquid additive through the gas exhaust valve­ (21), and for dosing, the liquid additive is pumped by means of the feed pump (18) from the liquid additive reservoir (20) to a junction point (9) with a water supply line (8).
