Problems solved by technology

However, the pressure released by the dissolved air is relatively high. When using a ball valve for sampling, there are problems of low bubble density and short residence time of the bubbles. The air flotation effect of the sample is quite different from the air flotation effect of the dissolved air water in the dissolved air system. Not conducive to accurate assessment of sewage return ratio

Embodiment 1

[0028] Such as figure 1 and figure 2 As shown, the release valve provided by the embodiment of the present invention includes: a spout piece 100 and a steady flow sleeve 200 sleeved with the spout piece 100, and a steady flow chamber 300 is formed between the spout piece 100 and the flow sleeve 200; the spout piece 100 is provided with The nozzle 101 and the steady flow sleeve 200 are provided with an inlet 201, and the nozzle 101 and the inlet 201 are in fluid communication with the steady flow chamber 300 respectively; the release valve is configured to disperse the flow from the inlet 201 to the steady flow chamber 300, The liquid flow from the steady flow chamber 300 to the nozzle 101 converges.

[0029] Specifically, the nozzle piece 100 is arranged coaxially with the flow sleeve 200 , and the flow chamber 300 has a circular structure on a section perpendicular to the axis of the flow sleeve 200 , and the spout 101 and the inlet port 201 are coaxial with the flow sleeve...

Embodiment 2

[0045] Such as figure 1 and image 3 As shown, the dissolved air water sampling system provided by the embodiment of the present invention includes: the dissolved air device 400 and the release valve provided in Embodiment 1, and the inlet port 201 is in fluid communication with the dissolved air device 400 .

[0046] Specifically, the air-dissolved water in the air-dissolving device 400 passes into the inlet 201 , and the mechanical energy of the dissolved air water can be reduced by blocking the flow-blocking end face, and the dissolved air water flows into the steady flow chamber 300 from the notch 102 . The air-dissolved water flows along the steady flow chamber 300 , through the steady flow chamber 300 , the dissolved air water has a steady flow effect, and the impact of the dissolved air water is further weakened by the friction of the side wall of the steady flow chamber 300 . The air-dissolved water flows into the spout 101 from the stabilizing flow chamber 300 throug...

Abstract

The invention provides a release valve and a dissolved air water sampling system, and relates to the technical field of dissolved air systems, the release valve provided by the invention comprises a nozzle piece and a steady flow sleeve sleeving the nozzle piece, and a steady flow cavity is formed between the nozzle piece and the steady flow sleeve; the nozzle piece is provided with a nozzle, theflow stabilizing sleeve is provided with a flow inlet, and the nozzle and the flow inlet are communicated with fluid of the flow stabilizing cavity. The release valve is configured to disperse the liquid flow from the flow inlet to the flow stabilizing cavity and converge the liquid flow from the flow stabilizing cavity to the nozzle. The release valve provided by the invention can be used for carrying out energy dissipation treatment on air-dissolved water.

Description

technical field [0001] The invention relates to the technical field of dissolved air systems, in particular to a release valve and a dissolved air water sampling system. Background technique [0002] Air flotation is a common process for solid-liquid separation in water treatment today. In order to verify the effect of air flotation, it is necessary to sample dissolved air water from the dissolved air system and test it. However, the pressure released by the dissolved air is relatively high. When using a ball valve for sampling, there are problems of low bubble density and short residence time of the bubbles. The air flotation effect of the sample is quite different from the air flotation effect of the dissolved air water in the dissolved air system. It is not conducive to accurately assessing the sewage return ratio. Contents of the invention [0003] The object of the present invention is to provide a release valve and a dissolved air water sampling system, which can pe...
