Description
Technical field
The present invention relates to a kind of positioning and locking device, refer to a kind of positioning and locking device of ball valve especially.
Background technique
The limit stoper of ball valve traditional is at present welded limiting bumping post on valve gap, and spacing after there is no locking device, valve rod is provided with handle, when handle rotates, one end of handle is against limiting block and lives in thus achieve spacing, does the easy loose or dislocation of limited post after repeatable operation like this, and when lacking position locking device, handle is easily touched because of casual the switching position changing ball valve, and these all affect the switching position precision of ball valve, easily makes ball valve produce interior leakage.
Summary of the invention
Technical problem to be solved by this invention is: the positioning and locking device providing a kind of ball valve, and this positioning and locking device can position the unlatching of ball valve or closed condition, and ball valve can also be locked, thus guarantees the precision of ball valve, avoids interior leakage.
For solving the problems of the technologies described above, technological scheme of the present invention is: a kind of positioning and locking device of ball valve, comprises the limited post be fixed on valve gap; Be fixed on the position-arresting disk on valve rod, this position-arresting disk is provided with spacing breach or restraining groove, described limited post is positioned at spacing breach or restraining groove; Described limited post is rotatablely equipped with locking block; The upper-end surface height of this locking block, lower than the lower end surface of position-arresting disk, this locking block is provided with dynamic locking hole, described position-arresting disk is provided with the quiet locking hole coordinated with dynamic locking hole, and this dynamic locking hole and quiet locking hole match to merge and lock by locking element.
As the preferred scheme of one, described quiet locking hole comprises to be opened quiet locking hole and closes quiet locking hole; The quiet locking hole of this unlatching is positioned at the opening end of spacing breach or restraining groove, and the quiet locking hole of described closedown is positioned at the shutdown side of spacing breach or restraining groove.
As the preferred scheme of one, described quiet locking hole also comprises quiet locking hole in the middle of at least one, the quiet locking hole in this centre is between the opening end and shutdown side of spacing breach or restraining groove, corresponding, locking block is provided with middle dynamic locking hole between the articulated position of locking block and dynamic locking hole, and the dynamic locking hole in this centre coordinates with the quiet locking hole in centre.
As the preferred scheme of one, described locking element is lock screw or spring bolt.
After have employed technique scheme, effect of the present invention is: the limited post of this positioning and locking device can coordinate with position-arresting disk to be made the unlatching precision of ball valve or close precision to improve, meanwhile, locking block can in the capable rotation of limited post, therefore, locking block is forwarded to dynamic locking hole and quiet locking hole on time, utilize locking element that position-arresting disk just can be made to lock, such valve rod would not rotate, even if encounter handle by mistake, also the spheroid of ball valve can not be driven to rotate, thus avoid making ball valve produce interior leakage.
Open quiet locking hole because described quiet locking hole comprises and close quiet locking hole again; The quiet locking hole of this unlatching is positioned at the opening end of spacing breach or restraining groove, and the quiet locking hole of described closedown is positioned at the shutdown side of spacing breach or restraining groove, and therefore, namely this locking block limits the enable possition of ball valve, also can limit closed position.
Again because described quiet locking hole also comprises quiet locking hole in the middle of at least one, the quiet locking hole in this centre is between the opening end and shutdown side of spacing breach or restraining groove, corresponding, locking block is provided with middle dynamic locking hole between the articulated position of locking block and dynamic locking hole, the dynamic locking hole in this centre coordinates with the quiet locking hole in centre, cause, this locking block can also limit the opening angle of ball valve, makes the adaptability of ball valve wider.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.

Fig. 2 is the plan view of Fig. 1;
In accompanying drawing: 1. handle; 2. position-arresting disk; 21. spacing breach; 22. open quiet locking hole; 23. close quiet locking hole; 3. valve rod; 4. valve gap; 5. limited post; 6. locking block; 61. dynamic locking holes.
Embodiment
Below by specific embodiment, the present invention is described in further detail.
As shown in Figure 1, 2, a kind of positioning and locking device of ball valve, comprises the limited post 5 be fixed on valve gap 4; Be fixed on the position-arresting disk 2 on valve rod 3, this position-arresting disk 2 is provided with spacing breach 21 or restraining groove, and in the present embodiment, position-arresting disk 2 is arrange spacing breach 21, described limited post 5 is positioned at spacing breach 21, if change restraining groove into, so limited post 5 is just constrained in restraining groove; Described limited post 5 is rotatablely equipped with locking block 6; The upper-end surface height of this locking block 6 is lower than the lower end surface of position-arresting disk 2, this locking block 6 is provided with dynamic locking hole 61, described position-arresting disk 2 is provided with the quiet locking hole coordinated with dynamic locking hole, this dynamic locking hole 61 and quiet locking hole match to merge and lock by locking element.Described locking element is lock screw or spring bolt.Position relationship between certain locking block 6 and position-arresting disk 2 can also be: the length of limited post 5 increased, and the lower end surface of locking block 6, higher than the upper-end surface of position-arresting disk 2, equally also can realize spacing.
Described quiet locking hole comprises to be opened quiet locking hole 22 and closes quiet locking hole 23; The quiet locking hole of this unlatching 22 is positioned at the opening end of spacing breach 21 or restraining groove, and the quiet locking hole of described closedown 23 is positioned at the shutdown side of spacing breach 21 or restraining groove.Certainly, described quiet locking hole also comprises quiet locking hole (not shown) in the middle of at least one, the quiet locking hole in this centre is between the opening end and shutdown side of spacing breach 21 or restraining groove, corresponding, locking block 6 is provided with middle dynamic locking hole 61 between the articulated position of locking block 6 and dynamic locking hole 61, and the dynamic locking hole 61 in this centre coordinates with the quiet locking hole in centre.
Working principle of the present invention is: move handle 1, handle 1 is with ovable valve stem 3 to rotate, the position-arresting disk 2 be fixed on valve rod 3 also rotates with it, when turning to limit position, namely when full open position or complete closed position, the opening's edge of spacing breach 21 just coordinates with limited post 5, thus reach location, now rotation lock block 6, make the dynamic locking hole 61 on locking block 6 and the quiet locking hole of the unlatching on position-arresting disk 2 22 and close quiet locking hole 23 to coordinate, then utilize lock bolt or spring bolt to be fixed by locking hole, thus complete the locking of valve rod 3.
