As an preferable embodiment of the present invention, four bolt holes screwed with the fixing bolt are disposed on the small circular plate.

As a preferred embodiment of the present invention, the diffusion middle tube is a cone with a large left and a small right.

As an optimized embodiment of the utility model, a clearance is reserved to pipe right-hand member opening in semicircular kuppe lateral wall and the diffusion.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. the utility model discloses a pipe inner wall integration is provided with water conservancy diversion spacing body in the diffusion, when the fluid passes through the diffuser originally, just withheld the condition that produces the vortex by water conservancy diversion spacing body, simple structure, and with diffuser integration shaping, use cost is lower.

2. The utility model discloses owing to be provided with the arc connection plate that four contained angles distribute in the inboard integration of big circular slab of inhibitor, one side integration that the little circular slab is close to the diffusion well pipe is provided with semi-circular kuppe, and semi-circular kuppe can disperse all directions with the fluid to separated by arc connection plate, further avoid producing the vortex and the backward flow condition.

Drawings

Other features, objects and advantages of the invention will become more apparent upon reading of the detailed description of non-limiting embodiments with reference to the following drawings:

fig. 1 is a schematic overall three-dimensional structure diagram of the vortex suppression structure of the diffuser of the jet pump according to the present invention;

fig. 2 is the overall sectional structure diagram of the vortex suppression structure of the diffuser of the jet pump of the present invention.

In the figure: the device comprises a large circular plate 1 of the suppressor, a diversion spacing part 2, an arc-shaped connecting plate 3, a small circular plate 4, a diffusion middle pipe 5, a semicircular diversion cover 6, a round opening 7, a fixing bolt 8 and a bolt hole 9.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a jet pump diffuser vortex restraines structure, includes the big plectane of inhibitor 1, the inboard integration of the big plectane of inhibitor 1 is provided with the arc connection plate 3 that four contained angles distribute, arc connection plate 3 is kept away from the one end screw thread of the big plectane of inhibitor 1 runs through there is fixing bolt 8, four arc connection plate 3 is kept away from the one end of the big plectane of inhibitor 1 has all laminated small circular plate 4, round mouth 7 has been seted up at the big plectane of inhibitor 1 middle part, round mouth 7 is connected with the integration of pipe 5 left ends in the diffusion, pipe 5 inner wall integration in the diffusion is provided with water conservancy diversion spacer body 2, one side integration that pipe 5 was provided with semi-circular kuppe 6 in the diffusion is close to.

In this embodiment (please refer to fig. 2), the small circular plate 4 is provided with four bolt holes 9 adapted to and screwed with the fixing bolts 8, so as to facilitate later detachment and replacement.

In this embodiment (see fig. 2), the diffuser middle tube 5 is a cone with a large left and a small right, so as to ensure the impact flow rate.

In this embodiment (see fig. 2), a gap is reserved between the side wall of the semicircular air guide sleeve 6 and the right end opening of the diffusion middle pipe 5, so as to ensure that the fluid is smoothly discharged from the gap.

When a jet pump diffuser vortex restraines structure uses, need explain, the utility model relates to a jet pump diffuser vortex restraines structure, including the big circular plate of inhibitor 1, water conservancy diversion spacer 2, arc connection plate 3, small circle board 4, pipe 5, semi-circular kuppe 6, round mouth 7, fixing bolt 8, bolt hole 9 in the diffusion, the part is the part that general standard spare or technical personnel in the field know, and its structure and principle all can learn the manual or learn through conventional experimental method for this technical personnel through the technique.
