Specific embodiment
With reference to the accompanying drawings and examples, this utility model is described in detail.
Embodiment one：A kind of anti-misoperation butterfly valve, as shown in figure 1, being rotatablely equipped with valve plate including valve body 1 in valve body 1
2, valve rod 3 is fixedly connected with valve plate 2, fixture block 18 is provided with 3 outer wall of valve rod, on 4 inwall of valve handle, snap ring 19, fixture block is provided with
18 are freely rotatably connected on valve handle 4 on valve rod 3 by blocking snap ring 19, and on the valve rod 3 inside valve handle 4, gap is set with card
Hoop 6, clip 6 is, with annulus jaggy, to be connected with elastic component 7 at the breach end of clip 6, and the elastic component 7 is spring, spring
The other end is connected on fastener tab 8, and the holding end of valve handle 4 is provided with holds ring 20, and 8 clamp of fastener tab is in one's hands the inwall of ring 20
On.
When the rotation of valve plate 2 is controlled when rotation valve rod 3 is needed, handss tense fastener tab 8 while holding ring 20, pass through
Clip 6 is tightened up and blocks valve rod 3 by back-moving spring, thus valve handle 4 is fixedly connected with valve rod 3 and will can be come from
The torque of valve handle 4 passes to valve rod 3, controls the rotation of valve plate 2 so as to by rotating valve handle 4, realizes the opening and closing of control butterfly valve；
After suitable position is turned to, ring 20 and fastener tab 8 are held in release, and fastener tab 8 is withdrawn under the action of the spring, while card
Hoop 6 loosens and gap is formed and valve rod 3 between, and now valve handle 4 is freely rotated relative to valve rod 3, even if someone's imprudence is touched by mistake
Valve handle 4 does not result in the rotation of valve plate 2 yet, prevents from touching the state for changing valve plate 2 by mistake.
Embodiment two：A kind of anti-misoperation butterfly valve, as shown in Fig. 2 the difference from embodiment one is：Clamp device 5
Including depression bar 9, depression bar 9 is rotatably installed on 4 inwall of valve handle by bearing 13, is also associated with multiple between 4 inwall of depression bar 9 and valve handle
Position spring 10, the front end of depression bar 9 are located above valve rod 3, and the front end of depression bar 9 is arranged to cross bayonet lock 11, relative in valve rod 3
Position is provided with the 11 phase clamping of draw-in groove 12 and cross bayonet lock.
When the rotation of valve plate 2 is controlled when rotation valve rod 3 is needed, while holding valve handle 4 and depression bar 9, depression bar 9 is lifted upwards,
Lever is formed under the supporting role of bearing 13, the front end of depression bar 9 is pressed downward using lever principle, be fitted together to cross bayonet lock 11
Enter in draw-in groove 12, so as to valve handle 4 is fixedly connected with valve rod 3, the torque of valve handle 4 is passed to into valve rod 3 and opening for valve plate 2 is controlled
Close, when turning to correct position and need not be rotated further by, unclamp depression bar 9, make in the case where back-moving spring 10 is acted on depression bar 9 recover former
Position, while cross bayonet lock 11 exits draw-in groove 12, now valve handle 4 can be freely rotated relative to valve rod 3, even if someone has touched valve handle by mistake
4 rotations for being also not result in valve rod 3, it is achieved thereby that the anti-misoperation of butterfly valve.
Embodiment three：A kind of anti-misoperation butterfly valve, as shown in figure 3, the difference from embodiment one is：Clamp device 5
Including sleeve 14, what sleeve 14 and valve handle 4 were made of one, sleeve 14 is rotated and is sleeved on valve rod 3, when 3 sets of sleeve 14 and valve rod
After dress, pin-and-hole 15 is laterally equipped with sleeve 14 and valve rod 3, on valve handle 4, bolt has rope 16, is connected with pin on rope 16
17。
When rotation valve rod 3 is needed, pin 17 is inserted into pin-and-hole 15, valve handle 4 and valve rod 3 are fixed as one, so as to incite somebody to action
Torque from valve handle 4 passes to valve rod 3, realizes by rotating valve handle 4 controlling the opening and closing of valve plate 2, when valve plate 2 is turned to
During correct position, pin 17 is extracted into pin-and-hole 15, now valve handle 4 and valve rod 3 lose fixation, valve handle 4 can be relative to valve rod 3 freely
Rotate, even if someone has touched the rotation that valve handle 4 does not result in valve rod 3 yet by mistake, it is achieved thereby that the anti-misoperation of butterfly valve.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, some improvement under the premise of without departing from this utility model principle and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
