Detailed description of the invention
Below in conjunction with specific embodiments and the drawings to a kind of executor of the present utility model
Locking butterfly valve is further described.
As shown in Figure 1-2, a kind of locking butterfly valve of executor, including butterfly valve body 1,
Connector 2 and actuator, described connector 2 is fixedly installed on described butterfly valve originally
Rotating shaft 1.1 top of body 1, described actuator includes worm gear 4 and worm screw 5, institute
State worm gear 4 to be in transmission connection with described worm screw 5, described connector 2 and described worm gear 4
Fixing.Compared with prior art, the locking butterfly valve of executor of the present utility model is logical
Cross and connector 2 is set rotating shaft 1.1 is connected with actuator, improve actuator
Operation and control intensity.Meanwhile, by rotary worm 5, by the band that is in transmission connection
Dynamic worm gear 4 rotates, and then the rotating shaft 1.1 being connected with worm gear 4 is rotated, thus,
The butterfly plate rotary of butterfly valve body 1 is angled, and then liquid is played cut-out
And throttling action.Actuator uses worm gear 4 transmission, and operational torque is little, and
Operate easy and convenient.Further, executor of the present utility model locking butterfly valve structure letter
Single, production cost is relatively low.
Seeing accompanying drawing 1-2, a kind of locking butterfly valve of executor of the present utility model is above-mentioned
On the basis of technical scheme, may is that described actuator also includes shell 3, institute
Toothed region 5.1 and the described worm gear 4 of stating worm screw 5 are all fixedly installed on described shell 3
In, the external stability of described shell 3 is provided with the first lock collar 6, and described worm screw 5 passes
Described first lock collar 6 is arranged, and described worm screw 5 is arranged with the second lock collar 7, described
First lock collar 6 and described second lock collar 7 can realize or release being locked.So,
The toothed region 5.1 of worm screw 5 and worm gear 4 are all fixedly installed in shell 3, worm screw 5
End through shell 3, be so easy to handle end and rotary worm 5.First lock
Dish 6 can be bolted on the outside of shell 3, and, worm screw 5 passes
First lock collar 6, the second lock collar 7 is set on worm screw 5；So, when worm screw 5 turns
After dynamic certain angle, by first lock collar 6 and the second lock collar 7 that be locked, it is ensured that
Worm screw 5 is not rotated further by relative to shell 3, thus, it is ensured that butterfly plate relative to
The open angle of butterfly valve body 1 is constant.Further preferred technical scheme may is that
Described first lock collar 6 and described second lock collar 7 are detachably locked by locking member
Fixing.So, by locking member control the first lock collar 6 and the second lock collar 7 it
Between locking, more convenient to operate.Further preferred technical scheme it may also is that
Described first lock collar 6 is provided with the first lockhole 6.1, and described second lock collar 7 is provided with
Second lockhole 7.1, described first lockhole 6.1 and the position of described second lockhole 7.1
The most corresponding, described locking member is by described first lockhole 6.1 and described second lock
Hole 7.1 is locked described first lock collar 6 and described second lock collar 7.So, lock
Tight parts can pass the first lockhole 6.1 and the second lockhole 7.1 that position is corresponding, logical
Cross and the first lockhole 6.1 and the second lockhole 7.1 that position is mutually corresponding is set, it is simple to lock
Fasten the first lock collar 6 and the second lock collar 7.First lockhole 6.1 and the second lockhole 7.1
Can be the multiple of regular distribution.Further preferred technical scheme can also be:
Described locking member is tapered end 8.So, tapered end 8 is utilized to lock, operation letter
Single, flexibly and easily, and tapered end 8 cost is relatively low, has saved production cost.
Seeing accompanying drawing 1-2, a kind of locking butterfly valve of executor of the present utility model is above-mentioned
On the basis of technical scheme, may is that the end of described worm screw 5 is provided with handwheel 9.
So, it is easy to manipulate worm screw 5 by handwheel 9 and rotates, real by rotating handwheel 9
Existing closure or openness, reduce the restriction requirement to working place.
Above-mentioned only a kind of specific embodiment in this utility model is illustrated, but
Can not be every according in this utility model as protection domain of the present utility model
Design spirit made equivalence change or modify, be all deemed to fall this practicality
Novel protection domain.
