Embodiment six:
Such as Figure 21 to Figure 26, a kind of forced seal ball valve, including valve ball 40 and valve rod 41.Valve ball is equipped with flap 42 and spiral is driven Driving wheel 44.Valve rod drive valve ball rotation, valve rod also drives screw driving wheel relative to valve ball rotation, screw driving wheel relative to Driving flap is jacked up and is withdrawn when valve ball rotates, and flap realizes the forced seal of ball valve when pressing valve seat 45.
Forced seal ball valve working method is: during shutoff operation, valve rod operation valve ball and flap rotate simultaneously, when When valve ball turns to closed position, valve ball stops operating, and screw driving wheel is rotated forward relative to valve ball, pushes flap from valve ball It stretches out and presses against and realize forced seal on valve seat.In the opening process of ball valve, screw driving wheel reversely turns relative to valve ball It is dynamic, drive flap to be detached from valve seat, then valve ball rotates simultaneously with flap, and valve ball turns to open position.
The operation torque of valve rod, screw driving wheel are filled by planetary roller spiral when in order to reduce the operation of forced seal ball valve Set driving flap.Common planetary roller screw needs the slot that switches tracks, for forced seal ball valve, flap only compared with Small stroke section is mobile, and rotation angle very little when driving screw thread works, the slot that switches tracks no longer is necessary structure.But root According to application and experiment discovery, such planetary roller screw has a defect that planetary roller screw is in reciprocating rotary During turning, due to factors such as the accuracy of manufacture and working environments, in planetary roller motion process it cannot be guaranteed that with external screw thread and Accurate positional relationship between internal screw thread, can generate some angular errors, i.e., every time when valve ball ontology turns to open position, Planetary roller cannot be guaranteed to reset to identical position, the angular errors accumulated after multiple reciprocating rotation make planetary roller and Retainer generates axial dipole field, when this axial dipole field is accumulated to a certain extent, retainer can be made to press externally threaded item or interior Screwed part, hinders the normal rotation of externally threaded item or interior threaded part, or even makes ball valve operation failure.
In order to solve this technical problem, the forced seal ball valve of the present embodiment uses a kind of retainer and resets planet rolling Male screw device.Screw driving wheel is equipped with external screw thread, and flap is equipped with internal screw thread.Multiple rows are equipped between external screw thread and internal screw thread Star roller 46, planetary roller are arranged between the external screw thread and internal screw thread by retainer 43.If the both ends of retainer are distinguished For first end face and second end face, the first end face and second end face of retainer are spiral end faces.First end face and second end face Spiral end face be helicoid corresponding with the helix of the external screw thread or internal screw thread.The helicoid of first end face is in rotation one The position in week forms the first convex edge 47, and the helicoid of second end face forms the second convex edge 48 in the position to rotate a circle.First is convex Edge and the second convex edge are opposite in the circumferencial direction direction of retainer.Screw driving wheel be equipped with the first collision block 49, the first collision block be from One pin shaft of externally threaded item end face protrusion.Flap is equipped with the second collision block 50, and the second collision block is also from interior threaded part end face One pin shaft of protrusion.First collision block is touched in the circumferencial direction of retainer and the first convex edge, circle of second collision block in retainer Circumferential direction and the second convex edge are touched.Since opening process is non-bearing rotation to planetary roller screw, planetary roller is being rolled The gap between external screw thread and internal screw thread can be utilized to generate sliding while dynamic, retainer and planetary roller can return to work and rise Beginning position.Thus make forced seal ball valve every time after completing opening operation, the first collision block of screw driving wheel or flap Second collision block can make retainer reset to identical position.
In original design, in opening process, screw driving wheel is rotated backward relative to valve ball forced seal ball valve first, It drives flap to be detached from valve seat, and makes to be recovered to the position contacted with valve ball, then valve ball rotates simultaneously with flap, and valve ball turns to Open position.It is this design the problem is that, flap is retracted into the position contacted with valve ball on the closed position of valve ball, this When flap still bearing the pressure of pipeline, and make between planetary roller and external screw thread and internal screw thread that there are pressure, planetary rollers Gap sliding, when the first collision block and the second collision block, which stir retainer, to be resetted, need can not be generated between external screw thread and internal screw thread Apply huge active force, increase the reset load of retainer, or damages planetary roller screw device, retainer and touch Block.
In the technical scheme of this embodiment, in the closing process of ball valve, flap is first ejected a small distance, then Valve ball and flap rotate simultaneously again, and when valve ball turns to closed position, valve ball stops operating, and screw driving wheel is relative to valve ball It rotates forward, flap, which is ejected and presses against on valve seat, realizes that the sealing of forced seal ball valve is closed.In the opening process of ball valve In, screw driving wheel is rotated backward relative to valve ball, first drive flap be detached from valve seat, when flap be detached from valve seat after, valve ball with Flap rotates simultaneously, and after valve ball turns to open position, screw driving wheel is rotated backward relative to valve ball once again, recycles flap To the position with valve ball body contacts, the reset of flap is realized.The retainer axial dipole field for closing valve and the accumulation of valve opening process causes Retainer is unidirectionally contacted with first collision block or the second collision block, thus with screw driving wheel or flap monodirectional locking, due to valve Ball has been pivoted into open position, is not subjected to pressure difference inside and outside flap, and answering for retainer can be completed using lesser driving force Position.
This just needs the operating device of forced seal ball valve to can be realized two sections of drivings operation to flap: one section is in valve It operates flap on the closed position of ball to move back and forth to valve seat direction, when shutoff operation and when valve seat obvolvent, opening operation and valve Seat is detached from.Another section be in the open position of valve ball operation flap telescopic moving on valve ball, when shutoff operation flap is stretched Valve ball a distance out makes planetary roller and retainer generate one section of return stroke;The return stroke is utilized when opening operation Flap is retracted into the position contacted with valve ball and resets retainer under non-bearing state.
