Description
Technical field
The present invention relates to the spheroid fixture of a kind of ball valve, it is specifically related to the sphere grinding fixture of a kind of spheroid.
Background technology
One of widely used valve of ball valve, its principle of work is the same with stopcock, is all by rotary spool to make valve opening and closing, but lighter than cock valve switching, and relative volume is little, it is possible to make heavy caliber ball valve. Ball valve sealing is reliable, and structure is simple, easy to maintenance, and trim and spheroid are everlasting closed state, not easily by medium erosion, thus widely use in industries such as oil, chemical industry, metallurgy.
The spheroid that ball valve generally comprises valve body, valve seat and is placed in valve seat, shown in Fig. 1,2, spheroid generally comprises two the symmetrical end faces 2 that are parallel to each other, and the distance between described two end faces 2 is less than the diameter of the sphere 3 of described spheroid 1, and described sphere 3 mates sealing mutually with the valve seat of ball valve; On described two end faces 2, equal convex is provided with a gudgeon 4, and described gudgeon 4 connects with the valve rod of ball valve; Also being provided with a through hole 5 with the axis perpendicular of described gudgeon 4 on described spheroid 1, described through hole 5 circulates for medium. Being arranged with an elongated slot 6 in described gudgeon 4, the alignment spheroid body-centered, center of elongated slot 6 is provided with a thimble hole 7. Specifically as described in Figure 2, when needing the sphere grinding carrying out spheroid, two ends thimble 8 generally being adopted to extend in thimble hole 7, position and clamp, then by the sphere 3 of spheroid near emery wheel, thimble 8 rotarily drives spheroid 1 rotation and carries out grinding. But owing to the frictional force between emery wheel with spheroid is bigger, and thimble 8 is also smaller with the contact area in thimble hole 7, and therefore spheroid is difficult to be driven to rotate. General way increases thimble 8 to the pressure of spheroid, but is easy to again spheroid compressive strain like this.
Summary of the invention
It is an object of the present invention to provide the sphere grinding fixture of the simple ball valve spheroid of a kind of structure.
The technical scheme of the present invention is: the sphere grinding fixture of a kind of ball valve spheroid, and described ball valve spheroid is the spheroid with two the symmetrical end faces that are parallel to each other, and the distance between described two end faces is less than the diameter of the sphere of described spheroid; On described two end faces, equal convex is provided with a gudgeon; Described spheroid is also provided with a through hole with the axis perpendicular of described gudgeon; An elongated slot it is arranged with in described gudgeon, the alignment spheroid body-centered, center of elongated slot is provided with a thimble hole, the sphere grinding fixture of described ball valve spheroid comprises a thimble, described thimble comprises a tip, described tip extend in described thimble hole, described thimble is fixed with a fixed block, the setting direction of described fixed block is vertical with the axis direction of thimble, be provided with an actuator on described fixed block in the position of the axis away from described thimble, described actuator extend in the elongated slot of described gudgeon and is closely attached on the side of described elongated slot.
Preferably, described fixed block by screw fastening on described thimble.
Preferably, the position of described actuator on described fixed block is adjustable.
Preferably, described fixed block being offered the groove body of the setting direction being parallel to fixed block, described actuator is inserted in described groove body, and is secured by bolts in described groove body.
It is an advantage of the invention that: coordinated by thimble and actuator, it is achieved location during the sphere grinding of spheroid and driving rotates, and efficiently solves the problem of spheroid distortion in prior art, and can ensure the sphere ground effect of spheroid well.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is the schematic perspective view of spheroid in prior art;
Fig. 2 is the sphere grinding schematic diagram of spheroid in prior art;
Fig. 3 is the sphere grinding schematic diagram of spheroid in the embodiment of the present invention one.
Wherein: 1, spheroid; 2, end face; 3, sphere; 4, gudgeon; 5, through hole; 6, elongated slot; 61, side; 7, thimble hole; 8, thimble; 9, fixed block; 10, actuator.
Embodiment
Embodiment one: shown in Fig. 1 and Fig. 3, a kind of ball valve spheroid, consistent with prior art, for having the spheroid 1 of two the symmetrical end faces 2 that are parallel to each other, distance between described two end faces 2 is less than the diameter of the sphere 3 of described spheroid 1, and described sphere 3 mates sealing mutually with the valve seat of ball valve; On described two end faces 2, equal convex is provided with a gudgeon 4, and described gudgeon 4 connects with the valve rod of ball valve; Also being provided with a through hole 5 with the axis perpendicular of described gudgeon 4 on described spheroid 1, described through hole 5 circulates for medium. Being arranged with an elongated slot 6 in described gudgeon 4, the alignment spheroid body-centered, center of elongated slot 6 is provided with a thimble hole 7.
The sphere grinding fixture of described ball valve spheroid comprises a thimble 8, described thimble 8 comprises a tip, described tip extend in described thimble hole 7, described thimble 8 is fixed with a fixed block 9, the setting direction of described fixed block 9 is vertical with the axis direction of thimble 8, being provided with an actuator 10 in the position of the axis away from described thimble 8 on described fixed block 9, described actuator 10 extend in the elongated slot 6 of described gudgeon 4 and is closely attached on the side 61 of described elongated slot 6.
Described fixed block 9 by screw fastening on described thimble 8. Certainly, equivalent fixing mode is all within protection scope of the present invention.
Preferably, the position of described actuator 10 on described fixed block 9 is adjustable. Such as: the groove body offering the setting direction being parallel to fixed block 9 on described fixed block 9, described actuator 10 is inserted in described groove body, and is secured by bolts in described groove body. Other similar regulative mode, such as, arrange a round on fixed block 9, and actuator 10 is inserted in different holes and regulates, or actuator 10 can be directly arranged to threaded stud, all within protection scope of the present invention.
The mode of operation of the sphere grinding fixture of the present invention once is simply described. Using relative two thimble 8 to carry out the location of spheroid, then regulate the position of actuator 10 so that it is be close on the side 61 of described elongated slot 6, rotate thimble 8, actuator can drive spheroid to rotate. Owing to thimble 8 only plays the effect of location, the rotate effect of spheroid realizes by actuator 10, therefore without the need to using too big clamping force.
The present invention is coordinated by thimble and actuator, it is achieved location during the sphere grinding of spheroid and driving rotates, and efficiently solves the problem of spheroid distortion in prior art, and can ensure the sphere ground effect of spheroid well.
Above-described embodiment, only for the technical conceive of the present invention and feature are described, its object is to allow person skilled in the art can understand the content of the present invention and implement according to this, can not limit the scope of the invention with this. All equivalences done according to spirit of the invention change or modify, and all should be encompassed within protection scope of the present invention.
