In order to solve the above technical problems, the utility model provides a kind of one-way valve structures for tailings conveying, including
The valve body of flowing hole is set on base, and the inside of the valve body sets multiple spheroids, and each spheroid includes a cast iron center spheroid, should
The Surface Machining of cast iron center spheroid has three grooves, and cast iron center spheroid is averagely divided into 8 curved surfaces by three groove, often
Column is respectively equipped with one curved surface；The appearance of the cast iron center spheroid pours into a mould wear-resisting layer of polyurethane.
In order to solve the above technical problems, the utility model additionally provides a kind of check valve interior spheroid knot for tailings conveying
Structure, including spheroid, spheroid include a cast iron center spheroid, and the Surface Machining of the cast iron center spheroid has three grooves, and this three
Cast iron center spheroid is averagely divided into 8 curved surfaces by groove, and column is respectively equipped with each curved surface；Outside the cast iron center spheroid
Table pours into a mould wear-resisting layer of polyurethane.
More guide rods are set in the valve body, and more guide rods enclose in valve body to be set the lifting to form corresponding multiple spheroids and lead to
Road, each liftway is interior to set a spheroid.
A diameter of 80mm of the flowing hole, a diameter of 80mm of the cast iron center spheroid, the spheroid it is a diameter of
110mm。
The width of three groove is respectively 9mm, and depth is respectively 4mm.
A height of 10mm of the column, a diameter of 6mm.
The utility model forms a wear-resisting practical ball using the firm parcel cast iron center spheroid of wear-resisting layer of polyurethane
Body, the wear-resisting spheroid are positioned in check valve, working in reciprocating mode are carried out with reference to check valve body inner guide, base and cover plate, in tail
The effect of control one-way flow is played in sand course of conveying, especially when coordinating reciprocal pump work, check valve is with needing high-frequency
Opening and closing work is carried out, impact, corrosion and abrasion of the tailings to valve body interior spheroid are very violent, provided by the utility model
Spheroid can play its performance characteristics, preferably overcome this working environment.
On the basis of such scheme, the sphere diameter of further requirement parcel layer of polyurethane is 110mm, internal cast iron center
Sphere diameter is 80mm, forms a kind of outer abrasion resistant, the ball device that inside is taken care of yourself.Require wear-resisting parcel layer of polyurethane simultaneously
Spheroid in cast iron center spherome surface process three grooves, wide 9mm, deep 4mm, while in 8 curved surfaces of cast iron center spheroid
On be respectively equipped with 1 high 10mm, a diameter of 6mm column, ensure that wear-resisting layer of polyurethane after cast is embedded in cast iron center ball
In the groove of body, and one is engaged with column, ensures that abrasion resistant polyurethane layer forms the state of relative securement after moulding by casting, keep away
Exempt to release phenomenon.Finally in order to ensure the maximum using effect of wear-resisting spheroid, it is desirable to the unidirectional valve base a diameter of 80mm of flowing hole,
Ensure that wear-resisting sphere diameter before 80mm is worn up to, does not influence service behaviour.
The utility model can not only ensure that tailings conveys check valve by simply changing the design structure of wear-resisting spheroid
Normal work, the service life of check valve also can be largely improved, improve equipment operation efficiency, reduced maintenance cost and match somebody with somebody
Part expense, promote Enterprise Healthy Development.The utility model spheroid both ensure that the weight of itself, also possess the spy of outer abrasion resistant
Property, it is simple and practical, it is stable and reliable for performance.

Embodiment
As Figure 1-Figure 2, the utility model, which is used for the one-way valve structures of tailings conveying, includes valve body 1, the valve body 1 it is interior
Portion sets multiple spheroids 2, and more guide rods 3 are set in valve body 1, and more guide rods 3 form corresponding multiple spheroids 2 in valve body 1
Liftway 5, each liftway 5 is interior to set a spheroid 2, and valve base 4 corresponding to each liftway 5 is provided with diameter
For 80mm flowing hole 6, ensure that spheroid 2 can normal use before diameter wears up to 80mm.Flowing hole 6 is put down on valve base 4
It is distributed.
As shown in Figure 3, Figure 4, spheroid 2 includes the cast iron center spheroid 21 of a diameter 80mm, the cast iron center spheroid 21
Surface Machining has three grooves 211, so that cast iron center spheroid 21 is averagely divided into 8 curved surfaces 212.The width of three grooves 211
Degree is respectively 9mm, and depth is respectively 4mm.1 high 10mm, a diameter of 6mm column 213 are respectively equipped with each curved surface 212.
The appearance of cast iron center spheroid 21 pours into a mould wear-resisting layer of polyurethane 22, ultimately forms a diameter 110mm wear-resisting spheroid 2, reaches
To the effect of anticorrosion antiwear.
As shown in figure 5, during work, tailings is flowed into by pulp-inlet pipe road 8, the bottom of check valve body 1 is reached by entering to starch flange port 7
Portion, under the gravity flow impact of tailings, wear-resisting spheroid 2 is rushed to the top of valve body 1 along guide rod 3, tailings is continued through
Check valve body 1 flows into pulp flange port 9, and continues towards in pulp pipeline 10, so as to complete whole tailings flow process.Instead
It, when reciprocating pump enters opposite impulse stroke, tailings is pressed into check valve body 1 from pulp pipeline 10, wear-resisting ball in valve
Body 2 is impacted by tailings, and in the presence of self gravitation, is fallen after rise at once along guide rod 3 to the flowing hole 6 on valve base 4,
So as to close flowing hole 6 so that tailings can not reach pulp-inlet pipe road 8 by check valve body 1, ensure that the unidirectional mistake of check valve
Flow effect.During working in reciprocating mode, wear-resisting spheroid 2 is by feat of itself superpower anticorrosion antiwear characteristic, it is ensured that steady for a long time
Fixed working condition.
