In order to overcome the disadvantages mentioned above of existing ball valve, this utility model provides a kind of reliable ball valve easy to operate, spacing
Slewing limit mechanism.
This utility model solves its technical problem and be employed technical scheme comprise that, a kind of ball valve slewing limit mechanism, revolution
Position-limit mechanism is positioned at the driving means installing port of ball valve, including slewing limit block and matched spacing adapter sleeve, connects
Set is connected with spheroid by contiguous block, and slewing limit block is symmetrical arranged two claw type lugs, and claw type lug is by limiting section and peace
Dress portion is constituted, and the limiting section of two claw type lugs is respectively provided with a confined planes, is confined planes I and confined planes II respectively, spacing
Angle between face I and confined planes II is 180 °, and the installation portion of claw type lug is fixed in the mounting groove being installed in valve body；Adapter sleeve
Upper end is provided with the connecting hole with driving means, at the limit convex that the circumferentially disposed of adapter sleeve matches with slewing limit block
Rise, spacing preiection arranges two confined planes, is confined planes III and confined planes IV respectively, between confined planes III and confined planes IV
Angle is for could be arranged to 90 °～180 °, to meet valve from spacing angle requirement different between 0 °～90 °；Valve is opening
When closing, the installation portion of claw type lug fixes the mounting groove being installed in valve body, and driving means drives spheroid by adapter sleeve, contiguous block
Carrying out switch motion, valve is when fully open position, and the confined planes I of slewing limit block abuts with the confined planes III of adapter sleeve, valve
When closed positions, the confined planes II of slewing limit block and the confined planes IV of adapter sleeve abut, it is ensured that valve the most spacing；
Sealed by sealing member between slewing limit block and valve body；Sealing member is passed through close between adapter sleeve and slewing limit block
Envelope.
Contiguous block upper surface arranges strip groove, and lower surface arranges strip boss, and strip groove is vertical with strip boss to be set
Put.
Arranging valve open position labelling at adapter sleeve upper surface, valve open position labelling is corresponding with the position of confined planes III.
The connecting hole of adapter sleeve could be arranged to variously-shaped being easy to such as interior hexagonal, square hole, flat hole, mounting hole, spline
Different driving means operation requirements.
The beneficial effects of the utility model are:
1, it is connected with driving means by the connecting hole structure of adapter sleeve, instead of traditional stem structure, save peace
Dress space so that valve overall structure is the compactest.
2, by the spacing preiection on adapter sleeve and slewing limit block claw type they fit, it is achieved that ball valve is internal spacing
For function, relatively other position limiting structures, save space the most spacing relatively reliable.
3, the strip groove on contiguous block is vertically arranged with strip boss, has separated medium and has acted on pushing away on adapter sleeve
Power, thus reduce driving moment.
4, adapter sleeve is provided with valve switch position mark, can prevent staff's maloperation.

Detailed description of the invention
As shown in Fig. 1,2,3,4,5,6,7, a kind of ball valve slewing limit mechanism, slewing limit mechanism is positioned at the driving of ball valve
Device installing port 1, including slewing limit block 4 and matched spacing adapter sleeve 3, adapter sleeve 3 is by contiguous block 5 and spheroid
6 connect, and slewing limit block 4 is symmetrical arranged two claw type lugs 14, and claw type lug is made up of limiting section 15 and installation portion 16, and two
It is respectively provided with a confined planes on the limiting section 15 of individual claw type lug, is confined planes I 17 and confined planes II 18 respectively, confined planes I 17
With the angle between confined planes II 18 is 180 °, in the fixing mounting groove 19 being installed in valve body of installation portion 16 of claw type lug；Even
