2, in flap of the present utility model and valve body, claiming wear-resisting rubber to make to increase its working life raceway shape unique in glue valve body makes it more reliable and stable; When one of them material feeding mouth input fluid of valve body, under fluid promotes, globe disk is automatically moved to that end of another material feeding mouth, and fluid flows out at discharge port, automatically completes pipeline and replaces.
3, the utility model is adapted at transfer ore pulp, carries in the system of sewage and use.
4, flap of the present utility model have that wear resistance is good, good springiness and the little feature of proportion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is one of structural representation of the utility model globe disk track.
Fig. 3 be the utility model globe disk track structural representation two.
Fig. 4 is the structural representation of the utility model globe disk.
Embodiment
With reference character, the utility model is further illustrated by reference to the accompanying drawings.
As shown in Figure 1,2,3, 4, a kind of ball shape change-over non-return valve, comprises the ball-type flap 3 in flat valve body and valve body; The valve pocket of described valve body is the valve pocket of semicylinder; In valve pocket, be Three way type structure, comprise the first material feeding mouth, the second material feeding mouth and discharge port; Described first, second material feeding mouth 1,2 is connected with Outer Tube by flange respectively with discharge port 5; On described valve interior wall, be arranged with first, second slide rail 4,5;
Described globe disk 3 is placed on first, second slide rail 4,5 under the effect of fluid impact power along first, second slide rail 4,5 reciprocating rollings;
The diameter of described globe disk 3 is greater than the diameter of first, second material feeding mouth 4,5 and discharge port, and ball-type flap 3 can be respectively by the first material mouth 4 or the second material feeding mouth 5 sealings;
Described first, second slide rail 4,5 is that circle triangle cone forms or consists of trapezoidal stage body by cross section;
Wherein the first slide rail 4 length are greater than the second slide rail 5;
Described valve body outside is respectively arranged with maintenance through hole 6 near discharge port two ends, on maintenance through hole 6, uses bolt seal; During maintenance, the bolt on two maintenance through holes 6 is backed out, then with hook, extend in valve body, clear up; Or water pipe is received on a maintenance through hole 6, and the residue in valve body is washed away in pressurization, from another maintenance through hole 6, get rid of waste liquid.Above-mentioned cleaning so that ball-type flap 3 on first, second slide rail 4,5, reciprocatingly slide more smoothly.
