Ball valve of the present invention is arranged the through hole of different-diameter, thus carry out regulating flow, meet the demand for control to flow, and simple to operately can open at any time or close ball valve, this ball valve reduces the wearing and tearing of valve body and Sealing simultaneously, keeps sealing effect, extends the working life of ball valve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the stereogram of ball valve.
Embodiment
Below in conjunction with Figure of description, the present invention will be further described:
Fig. 1 to Fig. 2 is the preferred implementation of ball valve provided by the invention, controls the size through ball valve fluid flow by ball valve.As shown in Figure 1 to Figure 2, this ball valve comprises the first valve seat 10, second valve seat 20, valve rod 30, ball valve 40 and Sealing 50, first valve seat 10 and the activity of the second valve seat 20 are installed, Sealing 50 is in seal clearance in the first valve seat 10 and the second valve seat 20, ball valve 40 is in the first valve seat 10 and the second valve seat 20, valve rod 30 is in and controls ball valve 40 between the first valve seat 10 and the second valve seat 20 and rotate, thus regulates the size through ball valve fluid flow.
Ball valve 40 comprises astrosphere groove 41, first through hole 42, second through hole 43 and third through-hole 44, astrosphere groove 41 is in the center of ball valve 40, and the first through hole 42, second through hole 43 is in same level with the central axis of third through-hole 44 and runs through ball valve 40 and is communicated with astrosphere groove 41.
The diameter of the first through hole 42, second through hole 43 and third through-hole 44 reduces successively, and such ball valve has three kinds of uninterrupteds to select, and meets the demand to flow control.Angle in ball valve between the first through hole 42, second through hole 43 of same half side-view and third through-hole 44 is followed successively by 60 degree, and such ball valve rotates 60 ° and can select to convert through-hole diameter, thus controls the flow by ball valve.
Ball valve 40 comprises closure 45 further, region in ball valve 40 between first through hole 42 to the 3rd hole 44 is closure 45, thus when the closed ball valve of needs, the through hole between the first valve seat 10 and the second valve seat 20 when ball valve turns to closure 45, can be closed.When ball valve 40 drives rotation by valve rod 30, ball valve 40 successively samsara rotates to the first through hole 42, second through hole 43, third through-hole 44 and this position of closure 45, thus the unlatching that can control ball valve also can control the size of flow in ball valve.
Ball valve 40 comprises operating groove 46 further, and operating groove 46 is arranged on the top of ball valve 40, and valve rod 30 is mounted in operating groove 46, drives ball valve 46 to rotate.Operating groove 46 is preferably cross, ball valve 40 firmly can be driven like this to rotate, and there will not be skidding.
As shown in Figure 1, the seal 50 is in seal clearance in the first valve seat 10 and the second valve seat 20, Sealing 50 comprises valve base sealing unit 51 and two ball valve sealing units 52 further, valve base sealing unit 51 is arranged on the first valve seat 10, seal the gap that the first valve seat 10 is connected with the second valve seat 20, two ball valve sealing unit 52 layerings are placed in the first valve seat 10 and the second valve seat 20, sealed spheroid valve 40 and the gap between the first valve seat 10 and the second valve seat 20.
As shown in Figure 1, valve base sealing unit 51 is valve washer, and valve washer is socketed on the first valve seat 10, is between the first valve seat 10 and the second valve seat 20, seals the gap that the first valve seat 10 is connected with the second valve seat 20.
As shown in Figure 1, each ball valve sealing unit 52 comprises elastic element 521 and seal washer 522 further, elastic element 521 is arranged on a side of seal washer 522, between the first valve seat 10 that elastic element 521 is in seal washer 522 and ball valve or the second valve seat 20.
Seal washer 522 comprises gasket seal 5221 and seal convexity 5222 further, elastic element 521 is arranged on a side of gasket seal 5221, seal convexity 5222 is arranged on the another side of gasket seal 5221, by seal convexity 5222 sealed spheroid valve 40 and the gap between the first valve seat 10 and the second valve seat 20.
As shown in Figure 2, further two grooves 47 of ball valve 40, two grooves 47 are arranged on the outer surface of ball valve 40, two grooves 47 coordinate with the seal convexity 5222 in ball valve sealing unit 52 respectively, thus the friction reduced between seal convexity 5222 and ball valve 40, keep sealing effect, extend the working life of ball valve.It is consistent that distance between two grooves 47 and two ball valve sealing unit 52 layerings are placed in distance in the first valve seat 10 and the second valve seat 20.
