Below in conjunction with accompanying drawing, the present invention is specifically introduced, so as to those skilled in the art's accurate understanding present invention's
Technical scheme.
Using the use state of forced seal ball valve as reference above and below as described herein, forced seal ball valve is in use state
When, it is vertically upper away from the direction on ground under the direction that points vertically upwards ground is.
As shown in Fig. 1-Fig. 7, the invention provides a kind of forced seal ball valve, including provided with the valve for fixed valve base 3
Body 1 and the ball valve provided with flap 8, flap 8 can realize that sealing coordinates with valve seat 3, and when valve is in close stance, ball valve is with it
Flap 8 realizes the sealing with valve seat 3, and when needing Open valve, flap 8 is tightened up in ball valve away from valve seat 3, follows ball valve to turn
Move to open position.
It can assemble to form forced seal ball valve shown in Fig. 2 using the structure shown in Fig. 1, assembling process is as follows：
Valve seat 3 can use the reserved location for being interference fitted and being pressed directly into valve body 1, the sealing between such valve seat 3 and valve body 1
Solve simultaneously.Little gear 10 is installed to axle corresponding to valve ball 5 and tightens little gear gland 18；Stud gear pressure ring 6 is put
Enter the threaded hole bottom of flap 8, then stud gear 7 is screwed in the threaded hole of flap 8；Before screwing, adjusting bolt gear pressure
The screw hole site of ring, the side of assembly six is then limited into rotation post and aligns pusher on earth with valve body 1；By four out of valve ball 5 runner
Lock screw is tightened；Finally upper pivot gear 9 is installed to corresponding to valve ball 5 on axle, and rotate upper pivot gear 9 to make flap
8 hold tightly with valve ball 5, complete the installation of valve ball 5.Valve ball 5 is put into from the top of valve body 1, then valve rod 16 is installed.First by torsion
Spring 17 coats butter and inserts position corresponding to valve rod 16, and valve rod 16 and torque spring 17 are then shifted into upper pivot tooth together
Wheel 9；The driving of the regular polygon of pivot gear 9, which is matched somebody with somebody, when the moment of torsion applied on valve rod 16 reaches setting value, in alignment merges valve rod
16 are pushed down into position.By valve body bolt 4 and tighten the installation that nut 15 realizes valve upper cover 11 again.Finally, by lid 12 on valve rod
Position is shifted onto along under valve rod 16, tightens lid screw 14 on valve rod, loads the key of valve rod 16, completes installation.
Specifically, as depicted in figs. 1 and 2, when needing to close valve, close valve torque and directly acted on by valve rod 16
Upper pivot gear 9, before flap 8 is aligned with valve seat 3, gear train is maintained at lock-out state, does not rotate, and valve rod 16 drives
Valve ball 5 is turned to after flap 8 is aligned with valve seat 3, and the rotation of valve ball 5 is limited part prevention, and valve rod 16, which continues to transmit, closes valve torque
The torque of torsion spring will be overcome so that upper pivot gear 9 rotates with respect to valve ball 5, torque is transmitted by little gear 10
To stud gear 7；Because stud gear 7 is connected with the spiral of flap 8, and the rotation of flap 8 is limited, under spiral guiding, spiral shell

During valve opening, torsion spring will apply torsion so that and valve ball 5 is maintained at the closing angle that valve seat 3 is directed at flap 8,
Now, close valve rotation and torque transmitted by little gear 10 and stud gear 7, tightened up in advance with driving flap 8 to depart from valve seat 3 in
Flap 8 and ball valve are also tightened up locking by superposition moment of torsion by ball valve, torsion spring；Then, valve rod 16 continues to rotate to valve opening position,
Valve ball 5 is driven to rotate to valve wide open.Using this structure type, during valve switch, flap 8 is locked with valve ball 5
Tightly, do not contacted with valve seat 3, realize the friction-free rotary of valve ball 5；And after valve is closed, again can by the pushing tow of flap 8 to
Valve seat 3 seals, and realizes forced seal.
Because when valve is closed, by the horizontal movement realization and the forced seal of valve seat 3 of flap 8, and flap 8 belongs to
A part for valve ball 5, then flap 8 and valve ball 5 should be maintained at the same horizontal position with valve seat 3, avoid in level height
Produce deviation.
And really as stated in the Background Art, meeting cumulative limit when due to valve actual processing and assembling, these tolerances can cause
There is deviation in the horizontal direction in valve ball 5 and the opposite valve seat 3 of flap 8.
In order to solve the above technical problems, present invention also offers a kind of valve ball height adjustment mechanism of forced seal ball valve,
Including height adjusting part 2, the height adjusting part 2 can be fixed with respect to valve body 1 in the vertical direction, can specifically be passed through with its lower end
Thrust piece abuts with valve body 1, and then is relatively fixed in the vertical direction with valve body 1；The bottom of valve ball 5 is provided with to be adjusted with the height
The adjustment hole 51 that part 2 coordinates, the adjustment hole 51 extends from the bottom to top, and with the flow passage of valve ball 5；When need adjust valve ball 5
During height, the operating parts such as spanner are stretched into by the runner of valve ball 5, act on height adjusting part 2, drive height adjusting part 2 along regulation
Hole 51 is moved, and because adjustment hole 51 is in above-below direction extension, and height adjusting part 2 is fixed in the vertical direction with respect to valve body 1, then
Height adjusting part 2 moves along adjustment hole 51, i.e., valve ball 5 moves along height adjusting part 2 in above-below direction, so as to drive valve ball 5 to change
And of Varying Depth, regulation valve ball 5 ensure that valve ball 5 is in same level with valve seat 3 with respect to deviation of the valve body 1 in level height
Highly.
With in the prior art the bottom of valve ball 5 shimming regulative mode compared with, using the present invention valve ball highly adjust
Mechanism, by driving height adjusting part 2 to move the regulation that can realizes the height of valve ball 5 along regulating part, reach compensation processing and
The purpose of assembly accumulation tolerance, it is simple and convenient；What is more important, can be by flowing due to adjustment hole 51 and flow passage
Road directly acts on height adjusting part 2, and then can realize that valve ball 5 is highly adjusted after the completion of assembling, without repeated disassembled and assembled, pole
The earth improves regulation efficiency；Also,, can after completing to adjust just because of height regulation can be realized after the completion of assembling
Easily to verify the accuracy of adjustment by the way that valve is rotated into close stance；Furthermore adjustment hole 51 is in valve ball 5
Bottom, do not influence completely the through-flow of valve and if necessary logical ball purging etc. operation.
Height adjusting part 2 can be arranged to the structure type with auto-lock function by those skilled in the art as needed,
So as to which after valve ball 5 is adjusted in place, the relative position of height adjusting part 2 and adjustment hole 51 is locked by auto-lock function.
Or the present invention is also provided with locking piece 13, after valve ball 5 is adjusted in place, the locking piece 13 is used to lock height
The relative position of the relative position of regulating part 2 and adjustment hole 51, i.e. lock height regulating part 2 and valve ball 5 is spent, valve ball 5 is limited
With the identical level height of valve seat 3.
The bottom of valve ball 5 can also set lock hole 52, lock hole 52 be in the top of adjustment hole 51 and with adjustment hole 51
Connection up and down, the lock hole 52 and flow passage, to cause adjustment hole 51 to pass through lock hole 52 and the flow passage of valve ball 5.It is high
The lower end of degree regulating part 2 is abutted by thrust piece with valve body about 1, is fixed in the vertical direction with relative valve body 1, thrust piece can
Think that thrust bearing etc. can bear the part of axial force.After valve ball 5 is adjusted in place, locking piece 13 can press on height
The upper end of regulating part 2 is spent, meanwhile, locking piece 13 coordinates with the locking of lock hole 52, and then maximum height limit regulating part 2 is in above-below direction
Motion, the relative position of lock height regulating part 2 and adjustment hole 51.
On the one hand, the lower end of height adjusting part 2 is abutted by thrust piece with valve body 1 in above-below direction, and then height is adjusted
The lower end of section part 2 is fixed, and now, lock hole 52 is located to the top of adjustment hole 51, so as to locking piece 13 is accessed from top,
So as to realize that the upper end of height adjusting part 2 positions.
On the other hand, to realize that locking piece 13 compresses contact to height adjusting part 2, lock hole 52 and height can be adjusted
Section part 2 is arranged to waney structure type, if the aperture of lock hole 52 is big, the aperture of adjustment hole 51 is small, height is adjusted
The upper end of part 2 can be stretched into lock hole 52, in order to which locking piece 13 is moved and can formed with height adjusting part 2 along lock hole 52
Compress contact；If the aperture of lock hole 52 is small, the aperture of adjustment hole 51 is big, locking piece 13 can extend downwardly into adjustment hole 51
Interior and with height adjusting part 2 upper end, which forms to compress, to be contacted.Or adjustment hole 51 and lock hole 52 can also use isometrical set
Put, when using equal aperture design, height adjusting part 2 for regulation silk post, locking piece 13 to be locking silk post, height regulation can be allowed
The top of part 2 is the cylinder that diameter is less than its major diameter of thread, or allows the bottom of locking silk post to be less than its major diameter of thread for diameter
Column structure, so, the effect to form the relation of compressing can also be reached.
When using not isometrical setting, the aperture that the aperture of lock hole 52 can be specifically less than to adjustment hole 51 is set, this
When, adjustment hole 51 is under, lock hole 52 upper, during processing, can be pulled out of hole in the bottom of valve ball 5, subdrilling macropore, then in macropore
Interior brill aperture, macropore are adjustment hole 51, keyhole formation lock hole 52.This processing mode is easily realized, and is processed more simple
It is single convenient.
Lock hole 52 can be coaxially disposed with adjustment hole 51, and lock hole 52 and adjustment hole 51 can be strictly at
Lower direction, i.e., angle of inclination is not present with above-below direction.Now, the latching force effect that locking piece 13 applies to height adjusting part 2
In the axial direction of height adjusting part 2, this axially corresponds to above-below direction, it is possible to increase the reliability of locking.
Or in when being circumferentially with multiple adjustment holes 51 of lower pivot around forced seal ball valve, lock hole 52 and regulation
Hole 51 can extend from the bottom to top, and relative above-below direction has less angle of inclination, now, is highly adjusted in each adjustment hole 51
Section part 2 component in the horizontal direction be present to the support force of valve ball 5, as long as in multiple adjustment holes 51 height adjusting part 2 support force
Component in the horizontal direction can be offset.
In detail, as Figure 2-Figure 5, height adjusting part 2 is specifically as follows regulation silk post, and locking piece 13 is specifically as follows
Silk post is locked, now, adjustment hole 51 and lock hole 52 are disposed as screwed hole, and height adjusting part 2 coordinates with the screw thread of adjustment hole 51,
Locking piece 13 and the screw thread of lock hole 52 coordinate, also, lock hole 52 and adjustment hole 51 is oppositely oriented.
When height adjusting part 2 is arranged to helicitic texture, it can be driven by rotation height regulating part 2 along adjustment hole 51
Motion, this rotary motion can improve the stability of adjustment, and it is possible to be realized by a small margin by the control to the anglec of rotation
Fine setting, and then improve the accuracy and precision of regulation.
Locking piece 13 is also configured as helicitic texture, identical with the structure type of height adjusting part 2, can be with height adjusting part
2 share an operating parts, can act on height adjusting part 2 by an operating parts, can also act on locking piece 13, real
Both existing drivings respectively.What is more important, after the height of valve ball 5 is adjusted in place by height adjusting part 2, locking piece 13 can
To be screwed in downwards in lock hole 52 by runner, and further rotate and abutted with the upper end of height adjusting part 2；Due to lock hole 52
Oppositely oriented with adjustment hole 51, the helical design of this opposite direction causes locking piece 13 to be transported in opposite directions with height adjusting part 2
It is dynamic, avoid locking piece 13 and moved up under the thrusting action of height adjusting part 2, and then ensure that the locking to height adjusting part 2
Reliability.The helical design of this opposite direction is not only simple, additionally it is possible to ensures the reliability of locking.
It is understood that height adjusting part 2 is not limited to above-mentioned regulation silk post, those skilled in the art can be as needed
Other structures form is set to, realizes that height is adjusted as long as can coordinate with valve ball 5.
It is further appreciated that the structure type of locking piece 13 is various, the concrete form of above-mentioned silk post is not limited to.For example, locking
Part 13 can also be lock pin, and now, lock hole 52 could be arranged to pin-and-hole, after the height of valve ball 5 is adjusted in place, by valve ball 5
Runner hammers into downwards pin, to press on the upper end of height adjusting part 2.
As shown in figure 4, the top of regulation silk post can set endoporus, apply the operating parts of rotating force for accessing,
Operating parts can think spanner, and endoporus specifically could be arranged to inner hexagonal hole, and correspondingly, operating parts can be inner hexagon spanner,
Rotated with inserting driving regulation silk post in endoporus.
As shown in figure 5, the top of locking silk post can also set endoporus, apply the operation of rotating force for accessing
Part, the endoporus that the endoporus is referred to adjust silk post are set.
For ease of distinguishing, the first endoporus 21 can will be defined as located at the endoporus of regulation silk post, by located at locking silk post
Endoporus is defined as the second endoporus 131.
The height of locking piece 13 can be configured, it is high to compress positioning to cause locking piece 13 and lock hole 52 to lock
After spending regulating part 2, the runner of the non-bulging valve ball 5 in upper end of locking piece 13, as shown in Figure 3.The design of this sunk type can make
Whole valve ball height adjustment mechanism is embedded in the bottom of valve ball 5, do not influence the through-flow of valve completely and logical ball if necessary purge etc.
Operation.
On the basis of the above, as shown in Fig. 2 forced seal ball valve is provided with the lower pivot being rotatablely connected with valve ball 5, valve ball 5
Bottom can be set correspondingly with adjustment hole 51 with adjustment apertures 51 and lock hole 52, lock hole 52 provided with three, and
Adjustment hole 51 and lock hole 52 can be circumferentially uniformly distributed around lower pivot, be connected with height in each adjustment hole 51 correspondingly
Regulating part 2, locking piece 13 is connected with correspondingly in each lock hole 52.
Using the equally distributed regulating part of this circumference, the circumferential of valve ball 5 can be carried out effectively by height adjusting part 2
Ground supports.Now, each height adjusting part 2 can synchronize regulation, to cause the keep level of valve ball 5, avoid valve ball 5 with respect to water
