Description
Technical field
The present invention relates to a kind of compensation sealing ball valve.
Background technique
Ball valve, generally include valve body, the spheroid be arranged in valve body, and the valve rod to match with spheroid, described valve body both sides are provided with medium channel, the corresponding spheroid place of described medium channel is provided with the valve seat matched with spheroid, traditional ball valve, its valve seat adopts elastic component to carry out elastic compensating sealing usually, but along with after ball valve Long-Time Service, especially in the case of a high temperature, the elastic restoring force of its elastic component is deteriorated gradually and causes compensation effect to be deteriorated gradually, thus have impact on the sealing between valve seat and spheroid.
Summary of the invention
For the deficiency that prior art exists, the object of the present invention is to provide a kind of compensation sealing ball valve improving sealing effect between valve seat and spheroid, longer service life.
For achieving the above object, the invention provides following technological scheme: a kind of compensation sealing ball valve, comprise valve body, be arranged on the spheroid in valve body, and the valve rod to match with spheroid, described valve body both sides are provided with medium channel, the corresponding spheroid place of described medium channel is provided with the valve seat matched with spheroid, described valve seat is provided with compensation sealing device, described compensation sealing device comprises moving part, described moving part radial location, axially movablely be arranged in described medium channel, described moving part is provided with and drives its driving mechanism moved axially, described driving mechanism drives described moving part to move to corresponding spheroid direction and compresses valve seat or move release valve seat to opposing spheres other direction.
By adopting technique scheme, when ball valve is opened, driving mechanism drives moving part to move to corresponding spheroid direction and compresses valve seat, make better to seal between valve seat and spheroid, when ball valve needs to close, driving mechanism drives moving part to move release valve seat to opposing spheres other direction, and spheroid can easily be closed, because moving part and driving mechanism all can adopt rigid material, and can not as elastic compensating sealing easy along with ball valve Long-Time Service compensation effect be deteriorated.Therefore, technical solution of the present invention, improves sealing effect between valve seat and spheroid.
The present invention is arranged further: described driving mechanism comprises live axle and sleeve, described live axle and sleeve are perpendicular setting, and to be matched transmission by umbrella gear between live axle with sleeve, described sleeve and moving part are arranged respectively in a tubular form, described sleeve socket-connects with moving part and is connected, and by screw-thread fit transmission between described sleeve and moving part, described sleeve is radially rotatablely arranged in described medium channel with axially locating, circumference, and described moving part circumference location is arranged in described medium channel.
By adopting technique scheme, during drive shaft turns, because live axle and sleeve are perpendicular setting, and to be matched transmission by umbrella gear between live axle with sleeve, then there is circumference rotation in sleeve, because sleeve is radially rotatablely arranged in described medium channel with axially locating, circumference, moving part is radial locates with circumference, be axially movablely arranged in described medium channel, and by screw-thread fit transmission between sleeve and moving part, moving part is then made to occur axially also to be moved, to compress valve seat or to discharge while circumference is rotated.
The present invention is arranged further: the corresponding valve seat one end of described moving part is provided with the end face matched with valve seat, described end face is set to the conical surface reduced gradually by the opposing spheres the other end to corresponding spheroid one end orient diameter, and described valve seat is correspondingly provided with the conical surface suitable with the end face of described moving part.
By adopting technique scheme, due to the mating reaction of moving part and valve seat conical surface, when moving part compresses valve seat, while moving part axially produces active force to valve seat, also active force is produced to the radial direction of valve seat, then improves the sealing between valve seat and valve body simultaneously.
The present invention is arranged further: described moving part is set in the outside of sleeve, is provided with lining in the outboard end of described medium channel, the setting equal to the internal diameter of sleeve of the internal diameter of described lining.
By adopting technique scheme, due to the effect of lining, decreasing medium washing away the compensation sealing device be partly placed in medium channel in medium channel, thus improve working life.
Below in conjunction with accompanying drawing, the invention will be further described.
Accompanying drawing explanation
Fig. 1 is the structure sectional view of the embodiment of the present invention;
Fig. 2 is the A portion enlarged view of Fig. 1;
Fig. 3 is the B portion enlarged view of Fig. 1.
Embodiment
See accompanying drawing 1 to accompanying drawing 3, compensation sealing ball valve disclosed by the invention, comprise valve body 1, be arranged on the spheroid 2 in valve body 1, and the valve rod 3 to match with spheroid 2, described valve body 1 both sides are provided with medium channel 101, described medium channel 101 corresponding spheroid 2 place is provided with the valve seat 4 matched with spheroid 2, described valve seat 4 is provided with compensation sealing device 5, described compensation sealing device comprises moving part 501, the radial location of described moving part 501, axially movablely be arranged in described medium channel 101, described moving part 501 is provided with and drives its driving mechanism moved axially, described driving mechanism drives described moving part 501 to move to corresponding spheroid 2 direction and compresses valve seat 4 or move release valve seat 4 to opposing spheres 2 other direction.By adopting technique scheme, when ball valve is opened, driving mechanism drives moving part 501 to move to corresponding spheroid 2 direction and compresses valve seat 4, make better to seal between valve seat 4 and spheroid 2, when ball valve needs to close, driving mechanism drives moving part 501 to move release valve seat 4 to opposing spheres 2 other direction, spheroid 2 can easily be closed, because moving part 501 and driving mechanism all can adopt rigid material, and can not easy as elastic compensating sealing along with ball valve Long-Time Service, compensation effect is deteriorated.Therefore, technical solution of the present invention, improves sealing effect between valve seat 4 and spheroid 2.
The present embodiment is arranged further: described driving mechanism comprises live axle 503 and sleeve 502, described live axle 503 and sleeve 502 are in perpendicular setting, and to be matched transmission by umbrella gear 504 between live axle 503 with sleeve 502, described sleeve 502 is arranged respectively in a tubular form with moving part 501, described sleeve 502 socket-connects with moving part 501 and is connected, and by screw-thread fit transmission between described sleeve 502 and moving part 501, described sleeve 502 radially with axially locating, circumference is rotatable to be arranged in described medium channel 101, described moving part 501 circumference location is arranged in described medium channel 101.Live axle 503 arranges driver element at relative sleeve 502 the other end, and driver element can adopt the modes such as electronic, pneumatic, manual, and the present embodiment adopts handwheel 505.By adopting technique scheme, when live axle 503 rotates, because live axle 503 and sleeve 502 are in perpendicular setting, and to be matched transmission by umbrella gear 504 between live axle 503 with sleeve 502, then there is circumference rotation in sleeve 502, due to sleeve 502 radially with axially locating, circumference is rotatable to be arranged in described medium channel 101, moving part 501 is radial locates with circumference, axially movablely be arranged in described medium channel 101, and by screw-thread fit transmission between sleeve and moving part, moving part 501 is then made to occur axially also to be moved while circumference is rotated, to compress valve seat 4 or to discharge.
