Description
Technical field
The utility model relates generally to hydrotechnics field, more particularly to a kind of pumping device wheel blade protection ring.
Background technology
Traditional pumping device wheel blade, its center has typically opened up inlet opening, and outside liquid can be fast under pressure
Enter in inlet opening, then taken away from the pipe joint of inlet opening opposite side by water pipe fastly.
Hydraulic pressure is larger moment when in this course, due to drawing water, in use, what the aperture of inlet opening was born
Impulsive force is also larger, and the aperture that inlet opening is easily caused after long-term use is worn and torn.
The content of the invention
In view of the deficienciess of the prior art, the utility model, which is aimed to provide, can eliminate the pumping device of inlet opening aperture abrasion
Wheel blade protection ring.
To achieve the above object, the utility model provides following technical scheme：
A kind of pumping device wheel blade protection ring, includes the body of annular, opens up fluted in the outer ring of the body,
Circumferentially arranged some dividing plates, are split the groove by the dividing plate in the groove, and the body has first circular
End face and the second circular end face, first circular end face and the second circular end face are symmetricly set on the both sides of the body,
Inlet opening is offered in first circular end face, sealing ring, the sealing ring front are provided with the aperture of the inlet opening
With first circular end face in the same direction, the back side of the sealing ring is abutted on the aperture of the inlet opening, in the sealing ring
On offer some screwed holes, the sealing ring is threaded on the inlet opening, is offered in the front of the sealing ring
Outer circle hole and interior circular hole, the outer circle hole, interior circular hole are arranged concentrically with the inlet opening, the outer circle hole and interior circular hole it
Between be formed with step surface, in second circular end face be provided with interface tube.
Improved as of the present utility model, the sealing ring is made up of rubber.
As further improvement of the utility model, internal thread is offered on the inwall of the interface tube.
Compared with prior art, the utility model has the advantage of：By setting sealing ring in water inlet position, improving
Water inlet can also be avoided directly to be impacted by current while sealing property, it is possible thereby to reduce the abrasion of inlet opening, prolonged
The service life of long whole wheel blade.
Brief description of the drawings
Fig. 1 is the structural representation of pumping device wheel blade protection ring in the utility model embodiment；
Fig. 2 is Fig. 1 rearview；
Fig. 3 is the structural representation of sealing ring in Fig. 1.
Embodiment
The embodiment to pumping device wheel blade protection ring in the utility model is described further referring to the drawings.
As shown in drawings, the present embodiment is a kind of pumping device wheel blade protection ring, includes the body 1 of annular, in body
Outer ring open up fluted 11, body can be embedded in the inside of pumping device by the groove, in a groove circumferentially wait between
Away from ground there is provided some dividing plates 12, multiple deciles are divided into by these dividing plates by groove.
The both sides of the body have the first circular end face 2 and the second circular end face 3, the first circular end face and the second circle respectively
Shape end surface symmetric is arranged on the both sides of body, inlet opening 21 is offered in first circular end face, in the inlet opening
Aperture is provided with the sealing ring 4 being made up of rubber, and rubber has certain elasticity and sealing property, can improve sealing ring
Sealing enables sealing ring to be close on the aperture of inlet opening described hereinafter simultaneously.Specifically, sealing ring front and institute
State the first circular end face in the same direction, the back side of the sealing ring is abutted on the aperture of the inlet opening, is opened on the sealing ring
Provided with some screwed holes 41, the sealing ring is connected to by fastener threads such as the stud, the screws that are located in screwed hole
One circular end face offers outer circle hole 42 and interior circular hole 43 on the part around inlet opening in the front of the sealing ring,
The outer circle hole, interior circular hole are arranged concentrically with the inlet opening, and step is formed between the outer circle hole and interior circular hole
Face 44, by setting the step surface to increase the contact area between sealing ring and current, for reducing suffered by unit area
Pressure so that sealing ring is not allowed fragile.In addition, being provided with interface tube 5 in the second circular end face.In the interface tube
Internal thread is offered on inwall.
It is described above to make preferred embodiment of the present utility model, do not depart from for the person of ordinary skill of the art
On the premise of the utility model principle, some variations and modifications can also be made, these also should be regarded as protection of the present utility model
Scope.
