Utility model content
For the problems referred to above, this utility model provides a kind of energy-saving venturi, can reach the mixing effect of fluid of high suction volume when influx is relatively low, can effectively solve influx low time the not enough difficult problem of suction volume.
This utility model is achieved through the following technical solutions above-mentioned purpose, a kind of energy-saving venturi, and including flow ipe, described flow ipe connects contraction section by smooth arc transition, and described contraction section connects contraction larynx mouth by smooth arc transition；Described contraction larynx mouth side arranges hybrid chamber, and the expansion larynx mouth that the internal axial line arranged with described contraction larynx mouth of described hybrid chamber is located on the same line；Described expansion larynx mouth one end connects expansion segment by smooth arc transition, and described expansion segment one end connects output channel by smooth arc transition；Described hybrid chamber top connection intake line.
Preferably, described contraction section is the contraction section of a kind of revolution cavity being made up of the face of cylinder and taper seat, and the radial dimension of described contraction section flows to reduce along fluid.
Preferably, the taper seat cone angle of described contraction section is 60 °-70 °.
Preferably, the radial dimension of described expansion larynx mouth is the radial dimension of twice of described contraction larynx mouth.
Preferably, described expansion segment is the expansion segment of a kind of revolution cavity being made up of the face of cylinder and taper seat, and the radial dimension of described expansion segment flows to increase along fluid.
Preferably, the taper seat cone angle of described expansion segment is 6 °-7 °.
Preferably, the axial line of described flow ipe, contraction section and contraction larynx mouth, expansion larynx mouth, expansion segment and output channel is located on the same line.
The beneficial effects of the utility model are:
The cone angle of contraction section the most of the present utility model is far longer than the cone angle of expansion segment, it is possible to ensures that fluid forms bigger negative pressure at hybrid chamber, can strongly suck fluid；
2. add hybrid chamber, traditional throat is designed as separate type, i.e. shrink larynx mouth and expansion larynx mouth, and the diameter of expansion larynx mouth is more than shrinking larynx mouth, increases fluid pressure differential, makes two fluids stronger in the mixing of hybrid chamber；
3. flow ipe, contraction section and contraction larynx mouth are that smooth arc transition connects, and decrease the pressure loss that fluid flows into, more economize on resources, have good economic benefit and social benefit, be suitable for promoting the use of.
