Specific embodiment
Below in conjunction with drawings and examples, the utility model is described in detail.
As shown in Figure 1, this multi-path integrated form Venturi tube includes ontology, ontology includes inlet cylinders pipe 1, entrance circle
Bobbin 1 and the perforation of at least one circular cone collapsible tube 2 (cone angle is preferably 50o-120o) connect, and each circular cone collapsible tube 2 successively connects
Connect 2-8 times that cylinder trunnion 3(length is preferably diameter) and circular cone diffuser 4 (cone angle is preferably 14o-40o), mainstream fluid from
Inlet cylinders pipe 1 enters in ontology, then branches to different circular cone collapsible tubes 2, the mainstream fluid warp in each circular cone collapsible tube 2
It crosses respective cylinder trunnion 3 and flows out ontology from circular cone diffuser 4 again；Ontology is radially equipped with negative pressure pipe at cylinder trunnion 3
5, as shown in Fig. 2, negative pressure pipe 5 is connected with disk body 6, disk body 6 offers the first hollow airway 61, the edge at outer rim at center
The second hollow airway 62 circumferentially is offered, the first hollow airway 61 and the second hollow airway 62 are mutually communicated with negative pressure pipe 5,
Each cylinder trunnion 3 extends to form two connecting tubes 7 to two sides, and one of connecting tube 7 and the first hollow airway 61 penetrate through
Connection, another connecting tube 7 are connected with the perforation of the second hollow airway 62, introduce fluid and enter in ontology from negative pressure pipe 5, by
Negative pressure at cylinder trunnion 3 influences, and a part flows in the first hollow airway 61, and another part flow to the second hollow airway 62
