The arrow direction indicated on dynamic direction and valve body is consistent, and the proper flow of medium otherwise will be truncated.Bottom valve should be mounted on water
The bottom end on water pump suction pipe road.When closure of check ring, water hammer pressure can be generated in pipeline, particularly with big mouth pipeline or high-voltage tube
Road will lead to the damage of valve, pipeline or equipment when serious.
Utility model content
Existing in the prior art for big mouth pipeline or pressure duct to overcome, check valve is easy impaired problem,
The utility model provides a kind of angle one-way valve.
Specific technical solution is as follows:
A kind of angle one-way valve, including valve body and spool, valve body lower surface two sides are provided with oil inlet and oil outlet,
The spool is arranged in valve inner, and the spool includes movable balls, spring and cover board, and one end of the spring is fixed at
On the inner wall of valve body left end, the other end of the spring is fixedly connected with movable balls, and the top of oil inlet is arranged in the cover board,
And one end of cover board is fixedly connected with spring bottom, the cover board bottom is fixedly installed inclination scraper plate, and the valve body left end is set
It is equipped with sliding slot, the sliding slot bottom is provided with spiral cover.
Preferably, the vertical cross-section of the cover board is " L " type, and the short side of the cover board is fixedly connected with lower spring end.
Preferably, the length of the cover board is not less than the width of oil outlet.
Preferably, the angle of the sliding slot and horizontal plane is 30 °~60 °.
Preferably, the sliding slot inner wall smooth and sliding slot inclined-plane is equipped with ceramics.
The utility model has the advantages that compared with prior art
(1) angle one-way valve provided by the utility model is provided with cover board, it is ensured that oil outlet does not flow back, and mitigates
The spool water hammer pressure suffered in closed check valve.
(2) the cover board bottom in the utility model is provided with scraper plate, and valve body is provided with sliding slot, process of the cover board in sliding
In the spot of valve body lower surface inner wall is cleared up to sliding slot, further improve the service life of valve.

Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
The utility model discloses a kind of angle one-way valves, as shown in Figure 1, including valve body 1 and spool, 1 lower surface of valve body
Two sides are provided with oil inlet 7 and oil outlet 8, and spool is arranged inside valve body 1, and spool includes movable balls 2, spring 3 and cover board 4,
One end of spring 3 is fixed on the inner wall of 1 left end of valve body, and the other end of spring 3 is fixedly connected with movable balls 2, and cover board 4 is set
It sets in the top of oil inlet 7, and one end of cover board 4 is fixedly connected with 3 bottom of spring, as shown in figure 3, the fixation of 4 bottom of cover board is set
It is equipped with inclination scraper plate 41, scraper plate 41 can strike off the spot of 1 bottom of valve body, and 1 left end of valve body is provided with sliding slot 5, sliding slot 5
Bottom is provided with spiral cover 6, and sliding slot 5 after opening spiral cover 6, can be purged spot for collecting spot.Preferably, cover board 4
Vertical cross-section be " L " type, the short side of cover board 4 is fixedly connected with 3 lower end of spring, and cover board 4 and the bottom of valve body 1 offset,
During 3 deformation of spring, the spot of 1 bottom of valve body can be struck off.The length of cover board 4 is not less than the width of oil outlet 8
The length of degree, cover board 4 is more than oil outlet 8, can prevent fluid reflux.The angle of sliding slot 5 and horizontal plane in the utility model
It is 30 °~60 °, it is preferred that the angle of sliding slot 5 and horizontal plane is 60 °, 5 inner wall smooth of sliding slot and 5 inclined-plane of sliding slot is equipped with pottery
