| 摘要 |
This invention relates to a mixing apparatus assembly with air gap separation, comprising a first duct (22), having an inlet mouth (235) and a diameter D, connected to an air gap valve (223) downstream of which a venturi mixing device (4) is connected, the air gap valve (223) comprising a nozzle (224) having an outlet (225) spaced apart by a separation distance (226) from a collecting duct (227), the first duct (22) and the air gap valve (223) forming a linear channel upstream of the outlet (225) of the nozzle (224), going from the inlet mouth (235) of the first duct (22) to the outlet (225) of the nozzle (224) and having a length L, the assembly being characterised in that the length L being not shorter than D and not longer than 20D, i.e. D≦̸L≦̸20D, and in that said linear channel is provided with a flow straightener (228). This invention further relates to an apparatus for mixing a liquid comprising such assembly. |
