Description
Technical field
The utility model belongs to unloading valve field, and in particular to a kind of unloading valve.
Background technique
At the discharge gate that unloading valve installation works under negative pressure, top receives the material of discharger discharge, by rotation
Impeller plays a part of conveying material, and is responsible for the effect of sealing, prevents from sucking air from discharge gate in process of pneumatic transmission,
Guarantee that the normal discharge of discharger as a kind of special unloading device, plays very big work in cleaning and cleaning
With.Existing unloading valve impeller generally includes shaft and blade, and blade arrangement is in the periphery of shaft, such blade wheel structure airtightness
It is to be improved；
In view of the above deficiencies, the purpose of the utility model is to provide a kind of unloading valves, and blade wheel structure good leak tightness can be true
Protect the stability of unloading valve work.
Utility model content
The purpose of the utility model is to provide a kind of unloading valve, blade wheel structure good leak tightness, it can be ensured that unloading valve work
Stability.
The utility model provides the following technical solution:
The upper end of a kind of unloading valve, including valve body and impeller, the valve body is equipped with feeding inlet, and the lower end of the valve body is equipped with
Discharge port, the impeller is generally spherical, and the impeller is set in the valve body, the cavity of the valve inner and the impeller
Match；The cavity connection of the feeding inlet, the discharge port and the valve inner；And the outside of the valve body is equipped with electricity
Machine, the drive shaft of the motor run through the center of the impeller；The periphery of the impeller is uniformly equipped with several grooves, described recessed
The whole trend of slot is parallel with the drive shaft of the motor.
Preferably, the feeding inlet cross section is in isosceles trapezoid shape in isosceles trapezoid shape, the cross section of the discharge port；
Preferably, the hexagonal shape of driving shaft cross section of the motor.
Preferably, polytetrafluoroethylene (PTFE) material is coated with outside the impeller.
Preferably, the structure of the impeller is integrally formed.
The utility model has the beneficial effects that
The impeller of the utility model be it is spherical, by spherical arcuate structure, area in sealing contact can be improved, and then improve
Sealing effect, it is ensured that the stability of unloading valve work.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.In the accompanying drawings:
Fig. 1 is the utility model section view；
Fig. 2 is impeller main view.
In the figure, it is marked as 1, valve body；2, feeding inlet；3, discharge port；4, impeller；5, groove；6, motor.
Specific embodiment
As shown in Figure 1 to Figure 2, the upper end of a kind of unloading valve, including valve body 1 and impeller 4, the valve body 1 is equipped with feeding inlet
2, the lower end of the valve body 1 is equipped with discharge port 3, and the impeller 4 is generally spherical, and the impeller 4 is set in the valve body 1, institute
The cavity inside valve body 1 is stated to match with the impeller 4；Sky inside the feeding inlet 2, the discharge port 3 and the valve body 1
Chamber connection；And the outside of the valve body 1 is equipped with motor, the drive shaft of the motor 6 runs through the center of the impeller 4；The leaf
The periphery of wheel 4 is uniformly equipped with several grooves 5, and the whole trend of the groove 5 is parallel with the drive shaft of the motor 6.Impeller 4
To be spherical, by spherical arcuate structure, the area in sealing contact between impeller 4 and valve body 1 can be improved, and then improve sealing effect
Fruit, it is ensured that the stability of unloading valve work；
Wherein, 2 cross section of feeding inlet is in isosceles trapezoid shape in isosceles trapezoid shape, the cross section of the discharge port 3；
So convenient for charging and discharging.The hexagonal shape of driving shaft cross section of the motor 6, hexagonal structure are convenient for the transmitting of power；
For the ease of the drive shaft turns of motor 6, rolling bearing also is set on valve body 1, allows the drive shaft of motor 6 through the axis of rolling
It holds, then connects with impeller 4；Polytetrafluoroethylene (PTFE) material is coated with outside the impeller 4, polytetrafluoroethylene (PTFE) is not glued with good
Property, frictional force is small；The structure of the impeller 4 is integrally formed, and integrated formed structure stability is good, long service life；
The working method of the utility model:
As shown in Figure 1 to Figure 2, material passes through the rotation of motor 6, band movable vane out of feeding inlet 2 enters impeller 4 groove 5
Wheel 4 rotation, groove 5 be aligned discharge port 3 after be discharged, due to impeller 4 be it is spherical, by spherical arcuate structure, impeller 4 can be improved
Area in sealing contact between valve body 1, and then improve sealing effect, it is ensured that the stability of unloading valve work.
The above is only the preferred embodiments of the utility model, are not intended to limit the utility model, although referring to before
Embodiment is stated the utility model is described in detail, it for those skilled in the art, still can be to preceding
Technical solution documented by each embodiment is stated to modify or equivalent replacement of some of the technical features.It is all this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
