Embodiment
Utility model is described further below in conjunction with the accompanying drawings：As shown in the figure, the DBB Two-way flow ball valves with interlocking structure,
Including valve body 1, it is characterised in that：Floating core 91 and fixed core 92, the fixing ball valve bottom are equipped with the valve body side by side
Portion is connected with the body base inner wall by shaft 93, and gap is equipped between the floating core and the body base inner wall
94, the floating core is equipped with the first valve rod 2 rotated synchronously, and first valve rod 2 is equipped with the first limit rotated synchronously
Position ring 21；The fixed core is equipped with the second valve rod 3 rotated synchronously, and second valve rod is equipped with second rotated synchronously
Spacing ring 31,21 peripheral outer wall of the first spacing ring include the first arc sections 211 and the first escape groove 212, second limit
Position 31 peripheral outer wall of ring includes the second arc sections 311 and the second escape groove 312, second arc sections and first arc sections
Interference is set, and first spacing ring makes described second spacing when being correspondingly arranged including first escape groove with the second arc sections
The rotary first position of ring；When being correspondingly arranged with first arc sections and second escape groove itself rotatable the
Two positions.Two ball valves are using a fixing ball valve and a floating ball valve, suitable for most occasion, as preferred
, interference said herein sets the sum of diameter for referring to the first spacing ring diameter and second spacing ring to be more than the first spacing ring
With the distance of center circle of the second spacing ring, that is to say, that when the first arc sections are contacted with second arc sections, both meeting cards
Firmly, lead to not rotate, spool can be that ball valve can also be butterfly valve etc., and being thus provided with first on the first spacing ring avoids
Groove, will not contact when the second arc sections of the second spacing ring rotate with the first escape groove, it is possible thereby to cancel interference, the
The second escape groove set on two spacing rings is also similarly, when needing the second spacing ring to rotate, when valve is in standard-sized sheet
During state, the first arc sections of the first limited block can stretch into the second escape groove of the second limited block, and the first limited block can be with this time
Carry out switching manipulation, it is impossible to individually the second limited block is operated；When valve is in full-shut position, the of the second limited block
Two arc sections enter the first escape groove of the first limited block, and the second limited block can operate at this time, and the first limited block can not be grasped
Make, so when needing Open valve, only first open floating core, fixed core could be opened；When needing to close valve, only
Fixed core is first closed, floating core could be closed, it is not necessary to provide extra locking device, you can formed with certain order
Latch-up structure, avoids the generation of artificial incorrect operation.
In the present embodiment, as shown in the figure, the fixed core circumferential direction wall is equipped with escape groove 925, the floating core
Part is transferred to the escape groove and makes the closed position that the fixing ball valve can not rotate and produce described keep away when being closed including valve
Groove is allowed to make the rotary open position of the fixing ball valve.Peripheral outer wall is equipped with escape groove on fixing ball valve, when valve closes
When closing, the escape groove is towards floating ball valve, and floating ball valve rotates its circumferential wall part and enters in escape groove, and valve is in complete at this time
Closed state and fixing ball valve can not rotate, when valve needs to open, it is necessary to first rotate floating ball valve and turn on, i.e., its
Runner is towards fixing ball valve（The width of runner is more than or equal to the width of escape groove）When, fixing ball valve is rotated from interference, fixed
Ball valve can just rotate unlatching, coordinate interlocking structure to use, and effect is more preferable.
In the present embodiment, as shown in the figure, further including for making second valve rod by locking second spacing ring
The locking piece 4 that can not be rotated.The second spacing ring is further fixed by locking piece, and then prevents maloperation, it is simple in structure, use
Safety.
In the present embodiment, as shown in the figure, second spacing ring is equipped with through hole 313, the valve body is equipped with spacing
Groove 15, the locking piece bottom are correspondingly arranged through the through hole 313 with the limiting slot, top be arranged on the through hole above and
Equipped with the upper cover 43 for manual operation.When locking is needed, the bottom of locking piece is stretched into limiting slot, such second
Spacing ring cannot just have rotated, and locking piece can be connected through a screw thread and is connected with through hole.
In the present embodiment, as shown in the figure, further including the positioning sleeve 42 being connected with the through hole, the locking piece middle-end is set
In in the positioning sleeve and being equipped with boss 421, at the top of the boss and the positioning sleeve inner wall between be equipped with elastic component 422.When
After locking piece is moved into place, upper cover is unclamped, locking piece can be stretched into limiting slot under the action of elastic component, play the work of pretension
With more convenient to use.
In the present embodiment, as shown in the figure, the elastic component is spring.
In the present embodiment, it is described as shown in the figure, being additionally provided with the first arc-shaped straight slot 215 on first spacing ring
Valve body is fixed with the first spacer pin 16, and the spacer pin upper end is arranged in first straight slot.The position of the arc groove can
With the angle initialization according to valve rod actual rotation, when spool goes to closed position, the first spacer pin is located at the one of the first straight slot
Inner wall is held, when spool goes to open position, the first spacer pin is located at the other end inner wall of the first straight slot.
In the present embodiment, as shown in the figure, first escape groove is arc-shaped slot.Structure is compacter.
In the present embodiment, it is described as shown in the figure, being additionally provided with the first arc-shaped straight slot 315 on second spacing ring
