Specific embodiment
Embodiment 1: as shown in Figure 1 and 2, a kind of switching device for gate valve, including valve body 1, valve plate 2 and valve rod 3, valve
1 upper end of body is equipped with gate valve cap 4, and 4 inner top of gate valve cap is equipped with the first supporting block 5, is equipped on the downside of the first supporting block 5 and opens downwards
The spring groove 6 of mouth, the first supporting block 5 and gate valve cap 4 are equipped with the through-hole passed through for valve rod 3, and valve rod 3 is equipped with limit plate 7,
Limit plate 7 is horizontally disposed, and holddown spring 8 is equipped between 6 bottom of limit plate 7 and spring groove, and valve rod 3 is equipped with rack gear 9, rack gear 9
It is engaged with partial gear 10, the shaft of partial gear 10 is rotatably installed on gate valve cap 4, the shaft one of partial gear 10
End is equipped with handle 11.
When specifically used, as shown in Figure 1, rotation partial gear 10, band carry-over bar 9 is moved up, thus with ovable valve stem 3
It moving up, valve plate 2 moves up, and valve is opened, meanwhile, limit plate 7 moves up, and squeezes holddown spring 8；As shown in Fig. 2,
Partial gear 10 is continued to rotate, the toothless part of partial gear 10 loses with rack gear 9 to be engaged, in the effect of holddown spring 8
Under, rack gear 9 moves down, so that valve plate 2 moves down, realizes the closing of valve.Opening for valve can be improved in the switching device
Speed is closed, especially suitable for frequent opening/shutting valve.
The upper end of the valve rod 3 is equipped with graduation mark 12.The distance that valve rod 3 moves up is judged by graduation mark 12, thus
Judge the open/close states of valve and the size of unlatching.
As shown in figure 4, the handle 11 is equipped with limiting through hole 16, gate valve cap 4 is equipped with limit hole 17, position-limitting pin 18
Insertion limiting through hole 16 and limit hole 17 limit handle 11.
When valve is in fully open state, limit hole 17 is corresponding with limiting through hole 16, by by pin 18 simultaneously
It is inserted into limiting through hole 16 and limit hole 17 realizes the locking of valve.On the one hand valve can be made to be in fully open state, it is another
Aspect conveniently causes valve to close the maloperation of handle 11.
6 side wall of spring groove is equipped with sliding slot 19,7 both ends of limit plate, 19 sliding along the chute.By the way that sliding slot 19 is arranged, to limit
Position plate 7 plays position-limiting action.
Embodiment 2: as shown in Fig. 1 ~ 3, the 3 upper end two sides of valve rod are equipped with the second supporting block 13, and valve rod 3 is equipped with and the
