Description
Technical field
The utility model relates to a kind of heavy caliber semispherical valve, particularly a kind of spool of heavy caliber semispherical valve.
Background technique
Ball valve is a kind of 90 degree revolution opening/shutting valves.Ball valve is the same with one section of straight pipe after all opening, and fluid resistance coefficient is less.Big-diameter ball valve is the ball valve of 500 millimeters～3000 millimeters of bores.
Ball valve has rotator shaped valve body, there is respectively the ball valve inlet/outlet of axis on same straight line the forward and backward both sides of valve body, the axial direction of ball valve inlet/outlet is the ball valve mobile direction of fluid in use, on valve body, there is the valve shaft vertical with the axial direction of ball valve inlet/outlet, on valve shaft, be connected with spool, in valve body, there is the valve seat matching with spool, between spool and valve seat, have sealing pair.The spool of ball valve has whole spherical valve core and hemisphere spool, and spool is that hemispheric ball valve is semispherical valve.
Semispherical valve has shell shape spherical crown spool, at the bottom of the spherical crown of spherical crown spool, be circular, be that the projection at the bottom of spherical crown of the spherical crown of spherical crown spool is round, the upper and lower both sides of spherical crown spool are connected with respectively link arm, the location, outer end of upper and lower link arm is connected on valve shaft, and the high place of the spherical crown 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, a side in valve body has the spherical crown valve seat matching with spherical crown spool, between spherical crown spool and spherical crown valve seat, has sealing pair.
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, when keying, and the angle that valve shaft will drive shell shape spherical crown valve core rotation 90 to spend.This semispherical valve is in the time ending the flow control valve of fluid as part conducting, part, because the spherical crown spool metering function that fluid is partly opened, fluid is to flow through between valve interior wall and the edge of spherical crown spool, the fluidised form of fluid is bad, flow resistance coefficient is larger, is not suitable as Flow-rate adjustment and uses.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, proposes a kind of opposite opened heavy caliber semispherical valve that is suitable for using as Flow-rate adjustment.
The utility model is realized with the following method.
Opposite opened heavy caliber semispherical valve has rotator shaped valve body, before valve body, rear both sides have respectively the ball valve of axis on same straight line to enter, outlet, ball valve enters, the axial direction of outlet is the ball valve mobile direction of fluid in use, on valve body, have with ball valve, the vertical valve shaft of axial direction of outlet, on valve shaft in valve body, use, the shell shape spherical crown spool that lower link arm is connected, the high place of the spherical crown 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, a side in valve body has the spherical crown valve seat matching with spherical crown spool, between spherical crown spool and spherical crown valve seat, there is sealing pair,
Spherical crown spool is the left side by mirror symmetry, right two shell shapes, half spherical crown spool composition, half spherical crown spool is semicircle in the projection at the bottom of the spherical crown of spherical crown spool, 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 being enclosed within on valve shaft, driven gear on the other same straight line of axis that is connected with 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 on the second valve shaft, have respectively by the driving gear that is connected of commutation idle wheel, on the second valve shaft, have with the driven gear on right half spherical crown spool and engage connected actuation gear.
The utility model is in the time 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.
While opening the utility model, driving valve shaft rotates, when valve shaft rotates, in driving left hemisphere hat spool to rotate towards a direction, drive the second valve shaft to rotate by the driving gear on the driving gear on valve shaft, commutation idle wheel and the second valve shaft, when the second valve shaft rotates, drive right half spherical crown spool 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, when left and right two and half spherical crown spools rotate backward respectively after certain angle, the utility model full open.
The utility model is from being closed to the process of unlatching, and fluid is to start to flow out from the centerline in valve body.
The utility model, when as flow control valve, is that the centerline in valve body flows through under the left and right half spherical crown spool metering function that fluid is opened in part, and the fluidised form of fluid is better, and flow resistance coefficient is less.The utility model is suitable for using as Flow-rate adjustment.
Below in conjunction with accompanying drawing, the utility model is further described.
