Further, the outer profile for determining claw and dynamic claw is in Y type.
The utility model has the following beneficial effects:
1. completing the non-return valve of SF6 and the company of collection air valve with regard to fast operating by a people by using the utility model
It connects, using being simple and convenient to operate, improves work efficiency: cam mandrel band moving cam being twisted by torque spanner and is rotated, so that
Dynamic claw, quiet claw easily dock non-return valve with collection air valve, dynamic claw and determine mobile steady between claw, and guarantee to couple by force
Degree and good rigidity, the uniform axially loaded of flange of non-return valve and collection air valve complete the gas collection of SF6, deflate；
2. the dynamic claw of the utility model determines the pop-up that claw prevents from collection air valve, reduces and dive to operator
In personal injury, the damage of collection air valve can be also prevented；
3. the cooperation of valve pool snap ring and dynamic claw, quiet claw can further prevent the pop-up of collection air valve, increase safety system
Number can also use under the non-return valve of different flange thicknesses and the operating condition of collection air valve；
If being processed 4. determining claw and dynamic claw using thicker steel plate, although dynamic claw and the sliding of claw mandrel are lighter,
But increase the weight of device and use difficulty, the design for determining claw and dynamic claw of Y type is so that weight saving, easy to use
(reduce the length of cam mandrel；It is twisted using spanner more convenient)；
5. the design limitation of the sliding block freedom degree of dynamic claw, it is inclined that anti-stop claw generates angle when claw mandrel slides
It moves, moving claw will not bite, stuck when resetting；
6. the utility model has the advantages of simple structure, components are few, easy to process, and the precision for needing to cooperate is low, easy to spread.
