28 upper ends are inserted into pilot hole 29, and the diameter of guide rod 28 is less than the diameter of ball-type caulking groove 12.
The application method of the utility model is as follows:
When needing to rotate handwheel 8, it can be positioned by position of the positioning device to gag lever post 16, make gag lever post
The weight 18 of 16 lower ends will not be in contact with spacing ball 13, and staff can rotate handwheel 8 at this time, thus logical
Crossing handwheel 8 and controlling valve rod 7 and rotate moves up and down opening and closing element 4, and after the completion of the regulation of handwheel 8, staff need to only remove positioning
The positioning of device, gag lever post 16 will move down under the action of pressing spring 20, press the weight 18 of 16 lower end of gag lever post
In the spacing ball 13 being located at immediately below it, 13 script of spacing ball is protruding to the part in card slot and is squeezed into ball-type caulking groove 12, this
When 18 lower surface of weight fit with 11 slot bottom of card slot, frictional force is generated between the two, since the diameter of weight 18 is equal to
The diameter of spacing ball 13 is bonded each other between weight 18 and the coaxial and adjacent spacing ball 13 of spacing ball, therefore once aggravates
When block 18 pushes one of spacing ball 13, the adjacent spacing ball 13 in 13 two sides of spacing ball will be with 18 outer wall phase of weight
Fitting is cut, stuck effect is played, the mounting means of spacing ball 13 causes spacing ball 13 easily to force dynamic, lateral power by longitudinal
Then extremely difficult to push to spacing ball 13, weight 18 is once stopped by the spacing ball 13 of two sides, when the gag lever post to be driven of handwheel 8
16 when moving in a circle, and the spacing ball 13 of 18 two sides of weight then can be firmly stuck by it, to play limit effect.
In summary it is found that the utility model can pass through friction between 11 slot bottom of weight 18 and card slot and weight
18 spacing ball 13 when pressing to 11 slot bottom of card slot positioned at its two sides can be firmly stuck by the position of gag lever post 16, makes gag lever post
Once pressing to 11 slot bottom of card slot under the action of pressing spring 20, the position of gag lever post 16 will obtain the weight of 16 lower ends
It is fixed, to make the position of handwheel 8 be fixed, when handwheel 8 is accidentally touched by people or since opening and closing element 4 is by water impact
When, gag lever post 16 is then capable of forming limitation firm together, the rotation of handwheel is effectively avoided, so that stuck valve rod 7, makes opening and closing element
4 open/close states are not in any change, guarantee stability when water flow flowing.
8 side wall of handwheel is equipped with several jacks to connect with movable span 15, and gag lever post is equipped with to match with jack 21
Location hole 22, positioning device includes the locating rod 23 in the jack 21, and 23 one end of locating rod is penetrated to location hole 22, separately
