Ball valve is to make sphere make rotation around the vertical line of valve channel center line by rotation valve rod to block or connect Jie to realize
The function of matter, and must assure that sphere reliably limits afterwards in place in valve open/close, but due to assemble not in place, operating mode is severe,
The problems such as valve rod deforms causes valve stem spacing unreliable, valve finally occurs and fits badly or open not congruent problem.One is researched and developed thus
Kind is compact-sized, easy to operate, limits reliable ball valve slewing limit mechanism, solves the above problems, has important show
Sincere justice.
Invention content
In order to overcome the disadvantages mentioned above of existing ball valve, the present invention to provide a kind of easy to operate, reliable ball valve revolution of limit
Position-limit mechanism.
The technical solution adopted by the present invention to solve the technical problems is a kind of ball valve slewing limit mechanism, slewing limit
Mechanism is located at the driving device installing port of ball valve, including slewing limit block and the connector sleeve of matched limit, and connector sleeve is logical
It crosses link block to connect with sphere, two claw type lugs is symmetrical arranged on slewing limit block, claw type lug is by limiting section and mounting portion
It constitutes, is respectively provided with a confined planes on the limiting section of two claw type lugs, is confined planes I and confined planes II, I He of confined planes respectively
Angle between confined planes II is 180 °, in mounting groove of the mounting portion fixing card loaded on valve body of claw type lug；Connect set upper side
Portion is provided with the connecting hole with driving device, in the circumferentially disposed and matched limit protrusion of slewing limit block of connector sleeve, limit
Two confined planes are set in the protrusion of position, are confined planes III and confined planes IV, the angle between confined planes III and confined planes IV respectively
To could be provided as 90 °~180 °, to meet valve limit angle requirement different between 0 °~90 °；Valve open and close when,
The mounting portion fixing card of claw type lug is loaded on the mounting groove of valve body, and driving device drives sphere to carry out by connector sleeve, link block
Switch motion, in fully open position, the confined planes I of slewing limit block abut valve with the confined planes III of connector sleeve, and valve is complete
When off position, the confined planes II of slewing limit block and the confined planes IV of connector sleeve abut, it is ensured that the reliable limit of valve；
It is sealed by sealing element between slewing limit block and valve body；It is close by sealing element between connector sleeve and slewing limit block
Envelope.
Strip groove is arranged in link block upper surface, and strip boss is arranged in lower face, and strip groove is vertical with strip boss to be set
It sets.
In connector sleeve upper surface, setting valve open position marks, and valve open position label is corresponding with the position of confined planes III.
The connecting hole of connector sleeve could be provided as that interior hexagonal, square hole, flat hole, kidney slot, spline etc. are variously-shaped to be convenient for
Different driving device operations require.
The beneficial effects of the invention are as follows：
1, it is connect with driving device by the connection pore structure of connector sleeve, instead of traditional stem structure, saves peace
Fill space so that valve overall structure is more compact.
2, by the limit protrusion and slewing limit block claw type they fit on connector sleeve, limit inside ball valve is realized
Function has been saved space while having been limited relatively reliable for other position limiting structures.
3, the strip groove on link block and strip boss are vertically arranged, and have been detached medium and have been acted on pushing away on connector sleeve
Power, thus reduce driving moment.
4, connector sleeve is equipped with valve switch position mark, can prevent staff's maloperation.

Specific implementation mode
As shown in Fig. 1,2,3,4,5,6,7, a kind of ball valve slewing limit mechanism, slewing limit mechanism is located at the driving of ball valve
Device installing port 1, including slewing limit block 4 and the connector sleeve of matched limit 3, connector sleeve 3 pass through link block 5 and sphere
6 connect, and two claw type lugs 14 are symmetrical arranged on slewing limit block 4, and claw type lug is made of limiting section 15 and mounting portion 16, and two
It is respectively provided with a confined planes on the limiting section 15 of a claw type lug, is confined planes I 17 and confined planes II 18, confined planes I 17 respectively
Angle between confined planes II 18 is 180 °, in mounting groove 19 of 16 fixing card of mounting portion loaded on valve body of claw type lug；Even
