Fig. 2 is a left view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
Fig. 1 is a front section view of the present utility model, is the length relation of three ball covers of visual representation the utility model, among Fig. 1 three ball covers is deployed in the same plane.The real space relation of three ball covers as shown in Figure 2.
A kind of energy-conservation Slow Close ball check valve of the present utility model, comprise a main valve body 2, main valve body 2 comprises left side 21, middle part 22, right side 23, the right-hand member of left side 21 is by solder joint 5 welding middle parts 22, the right-hand member at middle part 22 makes main valve body 2 constitute whole welding structure by solder joint 5 welding right sides 23.In the main valve body 2 is cavity, and main valve body 2 left ends are for going out head piece 1, and right-hand member is an inflow port 6.Fluid flows into from the inflow port 6 of main valve body 2, flows out from going out the head piece 1 of main valve body 2 behind the cavity of flowing through.
Side near inflow port in the cavity of main valve body 2 is equiped with a dividing plate 7, and dividing plate 7 is provided with at least two circular holes 8.At least two ball covers 3 are mounted on this dividing plate 7 one to one with above-mentioned circular hole 8.The quantity of circular hole 8 and ball cover is 3 in the present embodiment, but is not as limit.Be evenly distributed with above-mentioned three circular holes 8 with " product " font on the dividing plate 7.Three ball covers 3 are mounted on this dividing plate 7 one to one with these three circular holes 8.
Ball cover 3 is cylindrical in the present embodiment for the design of mesh screen formula, and this ball cover 3 also can be other geometrical shapies in other cases.Ball cover 3 one ends have circular opening 9, and this opening 9 is connected with circular hole 8 on the dividing plate 7, and opening 9 diameters are the same or bigger with above-mentioned circular hole 8, can supply in the fluid inflow ball cover 3.Be distributed with aperture on ball cover 3 the other ends and the ball cover sidewall, can flow out ball cover 3 by above-mentioned aperture for fluid.
Having a spheroid 4 in the ball cover 3, can be elastic spheres such as ball, also can be the hard spheroid, is good with elastic sphere.Spheroid 4 can be in ball cover move left and right, and spheroid 4 diameters are greater than above-mentioned opening 9 and circular hole 8 diameters, the side that opening 9 matches with spheroid 4 is provided with the inclined-plane, when making spheroid 4 be in the opening end of ball cover 3, can fit tightly with opening 9, guarantees the ne-leakage phenomenon.
That is, spheroid 4 moves to the right side when being inflow port 6 one sides, can block this opening 9 and circular hole 8 fully, and the spheroid position can not go out fluid from inflow port 6 one effluents shown in solid line among Fig. 1.When on the left of spheroid 4 moves to, promptly going out head piece 1 one sides, above-mentioned opening 9 and circular hole 8 are not closed, the spheroid position as shown in phantom in Figure 1, fluid is free to flow into from inflow port 6, and the aperture from the ball cover 3 flows out ball cover 3, flows out main valve body 2 through going out head piece 1 then.
