Description
Technical field
The utility model is related to water pump, in particular to a kind of anti-return immersible pump.
Background technology
Now, water pump utilizes and all trades and professions, immersible pump are the machinery for being capable of water lift, is widely used in various industries,
Due to frequent underwater, so often will appear the water of reflux in the pump housing, into the corrosion in the pump housing, making for immersible pump is influenced
Use efficiency.
Utility model content
The utility model provides a kind of anti-return immersible pump, and it is short to overcome existing immersible pump service life, pump housing content
The problem of easily retaining ponding.
In order to solve the above-mentioned technical problem, the utility model uses following technical scheme：
A kind of anti-return immersible pump, including the pump housing, pump housing lower part is electromechanics portion, and electromechanical portion top sets axis leaf portion, described
Water outlet connection outlet pipe in axis leaf portion, the pump housing bottom set water inlet, motor, the electricity are set inside electromechanical portion
Machine is connected by shaft coupling with the pump shaft in axis leaf portion, and the pump shaft is equipped with impeller, and the water outlet setting anti-return fills
It puts, the back-flow preventer includes baffle circle, and four fan shape baffles, the fan shape baffle size and four are set on the baffle circle
The size of/mono- baffle circle is identical, and the fan shape baffle is connected with baffle circle by movable rotation-shaft, wherein the first fan shape baffle
Two straight flanges at connect the first diaphragm seal, the second diaphragm seal is connected at two straight flanges of the second fan shape baffle corresponding thereto,
Described to set discharge outlet with corresponding be discharged on tube wall of the first fan shape baffle and the second fan shape baffle, the discharge outlet boundary is not
More than the boundary of the fan shape baffle.
Further, the discharge outlet goes out to set outside drainage plate.
Compared with prior art, the utility model has the advantages that：
The utility model sets back-flow preventer, when normal pumping in use, water is inhaled into from water inlet, due to motor and
The effect of impeller, water are put to water outlet, since four fan shape baffles are movable, so water washes fan shape baffle to water outlet open
At inside pipe wall, discharge outlet is just blocked, does not interfere with the normal extraction of water, when pump is stopped using, water inlet is sealed with outlet pipe
It closes, fan shape baffle of not intaking is fallen after rise to baffle circle, since liquid is fallen after rise to baffle circle in inertia outlet pipe, avoids falling into
In the pump housing, the purpose for preventing liquid reflux is played, protects the motor and impeller of body interior, increases the service life of immersible pump.

Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to Fig. 1 and Fig. 2.
As depicted in figs. 1 and 2, a kind of anti-return immersible pump of the utility model, including the pump housing 1,1 lower part of the pump housing is electromechanics portion
2, electromechanical 2 top of portion setting axis leaf portion 3 connects outlet pipe 5 at the water outlet 4 in the axis leaf portion 3, and 1 bottom of the pump housing is set
Water inlet 6, electromechanical 2 inside setting motor 7 of portion are put, the motor 7 is connected by shaft coupling 8 with the pump shaft 9 in axis leaf portion 3, institute
It states pump shaft 9 and is equipped with impeller 10, back-flow preventer 11 is set at the water outlet 4, and the back-flow preventer 11 includes baffle circle
12, four fan shape baffles 13 are set on the baffle circle 12, and 13 size of fan shape baffle is big with a quarter baffle circle 12
Small identical, the fan shape baffle 13 is connected with baffle circle 12 by movable rotation-shaft 14, wherein two of the first fan shape baffle 131 are straight
The first diaphragm seal 132 is connected at side, the second diaphragm seal 134 is connected at two straight flanges of the second fan shape baffle 133 corresponding thereto,
Discharge outlet 15, the row are set on described and 133 corresponding 5 wall of outlet pipe of the first fan shape baffle 131 and the second fan shape baffle
15 boundary of the mouth of a river is no more than the boundary of the fan shape baffle 13, and further, the discharge outlet 15, which goes out, sets outside drainage plate 16.
