Ball valve is a kind of 90 degree of revolution opening/shutting valves.Ball valve is the same with one section of straight pipe after all opening, and Flow Resistant Coefficient is less.Big-diameter ball valve is the ball valve of bore 500 millimeters ~ 3000 millimeters.
Ball valve has rotator shaped valve body, the front and rear sides of valve body has axis ball valve inlet/outlet on the same line respectively, the axial direction of ball valve inlet/outlet is the direction of ball valve fluid flowing in use, valve body there is the valve shaft vertical with the axial direction of ball valve inlet/outlet, valve shaft is connected with spool, there is the valve seat matched with spool in valve body, between spool and valve seat, have sealing pair.The spool of ball valve has whole spherical valve core and hemisphere spool, and spool is hemispheric ball valve is semispherical valve.
Semispherical valve has shell shape spherical crown spool, circular at the bottom of the spherical crown of spherical crown spool, namely the projection of the spherical crown of spherical crown spool at the bottom of spherical crown is round, the upper and lower both sides of spherical crown spool are connected with link arm respectively, the location, outer end of upper and lower link arm is connected on valve shaft, and the spherical crown height place straight line of spherical crown spool is vertical with valve shaft, and the spherical crown centre of sphere of spherical crown spool is on the axis of valve shaft, there is the spherical crown valve seat matched with spherical crown spool side in valve body, has sealing pair between spherical crown spool and spherical crown valve seat.
In prior art, the spherical crown of semispherical valve spherical crown spool is overall spherical crown.This semispherical valve is suitable for the full opening/shutting valve as full conducting, full cut-off fluid, and during keying, valve shaft will drive the angle of shell shape spherical crown valve core rotation 90 degree.This semispherical valve is when the flow control valve as part conducting, part cut-off fluid, because fluid is by the spherical crown spool metering function of partly opening, fluid flows through between valve interior wall and the edge of spherical crown spool, the fluidised form of fluid is bad, flow resistance coefficient is comparatively large, is not suitable as Flow-rate adjustment and uses.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, proposing a kind of opposite opened heavy caliber semispherical valve be suitable for as Flow-rate adjustment.
The present invention is achieved using the following method.
Opposite opened heavy caliber semispherical valve has rotator shaped valve body, before valve body, rear both sides have axis ball valve on the same line to enter respectively, outlet, ball valve enters, outlet axial direction be ball valve in use fluid flowing direction, valve body has and enters with ball valve, the valve shaft that the axial direction exported is vertical, valve shaft in valve body is used, the shell shape spherical crown spool that lower link arm is connected, the spherical crown height place straight line of spherical crown spool is vertical with valve shaft, the spherical crown centre of sphere of spherical crown spool is on the axis of valve shaft, there is the spherical crown valve seat matched with spherical crown spool side in valve body, sealing pair is had between spherical crown spool and spherical crown valve seat,
Spherical crown spool is by a left side for mirror symmetry, right two shell shape half spherical crown spools composition, half spherical crown spool at the bottom of the spherical crown of spherical crown spool on projection be semicircle, left, on having respectively between right half spherical crown spool and valve shaft, lower link arm, on left hemisphere hat spool, lower link arm location is connected on valve shaft, on right half spherical crown spool, lower link arm has the axis hole be enclosed within valve shaft, the other driven gear be connected with on the same straight line of axis of axis and valve shaft of axis hole, there is second valve shaft parallel with valve shaft in valve shaft front on valve body, valve shaft with the second valve shaft has respectively the driving gear be connected by the idle wheel that commutates, second valve shaft there is the actuation gear engaging with the driven gear on right half spherical crown spool and be connected.
The present invention is when closing, and left and right two and half spherical crown spools are merged into spherical crown spool, on the valve seat of spherical crown spool in valve body.
When opening of the present invention, driving valve shaft rotates, when valve shaft rotates, while drive left hemisphere hat spool rotates towards a direction, the second valve shaft is driven to rotate by the driving gear on the driving gear on valve shaft, commutation idle wheel and the second valve shaft, when second valve shaft rotates, right half spherical crown spool is driven to rotate to another way by the driven gear on the actuation gear on the second valve shaft and right half spherical crown spool link arm, after left and right two and half spherical crown spools rotate backward certain angle respectively, full open of the present invention.
The present invention is from the process being closed to unlatching, and fluid flows out from the centerline in valve body.
The present invention is when as flow control valve, and fluid is that the centerline in valve body flows through under the left and right half spherical crown spool metering function of part unlatching, and the fluidised form of fluid is better, and flow resistance coefficient is less.The present invention is suitable for using as Flow-rate adjustment.
Below in conjunction with accompanying drawing, the present invention is further described.
