Specific embodiment
Invention 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：Be equipped with floating core 91 and fixed core 92 in the valve body side by side, the fixing ball valve bottom with
The body base inner wall is connected by shaft 93, and gap 94 is equipped between the floating core and the body base inner wall,
The floating core is equipped with the first valve rod 2 rotated synchronously, and first valve rod 2 is equipped with the first spacing ring rotated synchronously
21；The fixed core is equipped with the second valve rod 3 rotated synchronously, and second valve rod is equipped with the second /V rotated synchronously
Ring 31,21 peripheral outer wall of the first spacing ring include the first arc sections 211 and the first escape groove 212, second spacing ring
31 peripheral outer walls include the second arc sections 311 and the second escape groove 312, and second arc sections are interfered with first arc sections
It sets, first spacing ring includes making second spacing ring can when first escape groove is correspondingly arranged with the second arc sections
With the first position of rotation；Itself rotatable second when being correspondingly arranged with first arc sections and second escape groove
It puts.Two ball valves are using a fixing ball valve and a floating ball valve, suitable for most occasion, as preference,
Interference said herein set the sum of diameter for referring to the first /V ring diameter and second spacing ring be more than the first spacing ring and
The distance of center circle of second spacing ring, that is to say, that when the first arc sections are contacted with second arc sections, the two can be blocked,
Leading to not rotate, spool can be ball valve or butterfly valve etc., and the first escape groove is thus provided on the first spacing ring,
It will not be contacted when the second arc sections of the second spacing ring rotate with the first escape groove, it is possible thereby to cancel interference, second
The second escape groove set on spacing ring is also similarly, when the second spacing ring is needed to rotate, when valve is in standard-sized sheet shape
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 at this time
Row switching manipulation, it is impossible to individually be operated to the second limited block；When valve is in full-shut position, the second of the second limited block
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 is inoperable,
So when needing Open valve, floating core is only first opened, fixed core could be opened；When needing to close valve, only first
Fixed core is closed, floating core could be closed, additional locking device need not be provided, you can be formed with the lock of certain order
Determine structure, avoid 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
Slot 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, and cooperation interlocking structure uses, and effect is more preferable.
In the present embodiment, as shown in the figure, further including to make 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, it uses
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 /V
Slot 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 that is connected with the through hole, the locking piece middle-end is set
In in the positioning sleeve and equipped with boss 421, elastic component 422 is equipped between the boss and positioning sleeve inner wall top.When
After locking piece is moved into place, upper cover is unclamped, locking piece can be stretched under the action of elastic component in limiting slot, play the work of preload
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
Valve body is fixed with the second spacer pin 17, and the two spacer pins upper end is arranged in second straight slot.
