Embodiment
It should be noted that, when not conflicting, the embodiment in the present invention and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
A kind of easy-operating anti-in let out butterfly valve, as depicted in figs. 1 and 2, comprise valve rod 1, valve body 2 and the cylindric valve seat 3 be arranged in valve body 2 and control the valve plate 4 of butterfly valve flow; Described valve rod 1 radially runs through described valve body 1 and valve seat 2, and can rotate in valve seat 3; Described valve plate 4 is arranged in valve seat 3 by valve rod 1; Be provided with in described valve seat 3 and coordinate with described valve plate 4 concave surface 5 that butterfly valve cuts out; Described concave surface 5 along the circumferencial direction of valve seat 3 inwall around setting; One end that described valve rod 1 stretches out valve body 2 is provided with spanner 6.
It should be noted that, during operation valve plate 4 closure valve, valve plate 4 is only had to enter in the scope of concave surface 5, can realize damming, effectively ensure that the reliability of valve closes, from another angle, even if wear and tear in some position of concave surface 5, also valve plate 4 can be coordinated with other position of concave surface 5, play the effect of closure valve.This just effectively avoids, after impurity wearing and tearing valve seat 3 inwall of sewage in the past, and the problem of letting out in easily occurring.
Wherein, as shown in Figure 3, described valve plate 4 entirety is in disc-shaped structure, and its outer circumferential edges is provided with the lip 7 matched with concave surface 5 inwall on valve seat 3, and lip 7 coordinates reliably with valve seat 3 inwall, and effectively prevent the leakage of butterfly valve inside, operational safety is high.
Wherein, the U-shaped structure of described lip 7, such benefit is, lip 7 defines dual cooperation with valve seat 3 inwall, serves the effect of double-layer seal, effectively prevent the leakage in valve, even if a lateral wearing of lip 7, the effect of damming when also can not affect closed.
Wherein, described valve seat 3 internal surface is provided with wearing layer, and in the process opening and closing valve, the impurity in sewage can not wear and tear valve seat 3 inwall easily, makes this butterfly valve wear-resisting durable, effectively improves the working life of valve.
Wherein, described concave surface 5 is provided with chamfering with valve seat 3 interior thereof place, and when closed butterfly valve, valve plate 4 can enter in concave surface 5 scope smoothly, and lip 7 coordinates with valve seat 3 inwall, can not produce clamping stagnation.
Wherein, described spanner 6 is Telescopic shaft type structure, when needing, can extend spanner 6 length, laborsaving, easy to operate, especially butterfly valve service time longer after, the spanner of common butterfly valve is generally difficult to twisting, now, by the spanner lengthened, can unusual this butterfly valve of labour-saving closure or openness.
Wherein, described valve body 2 is also provided with dredging device; Described dredging device comprises and is arranged on one end on valve body 2 and stretches into the liquid storage cover 9 dredging bar 8 of valve seat 3 and valve body 2 hidden at dredging bar 8 place; Be provided with the first Sealing 10 between described dredging bar 8 and valve body 2, between described dredging bar 8 and described liquid storage cover 9, be provided with the second Sealing 11.
The first Sealing 10 and the second Sealing 11 arranged, effectively prevents fluid seepage from arriving external contamination environment.
Like this, by dredging the stirring of bar, and upper and lower pull, can when not dismantling butterfly valve, valve seat 3 inner chamber is effectively dredged, can effectively clear up stacking foreign material, even if there is part of contaminated water to leak with the junction of valve body 2 from dredging bar 8, also can be stored by liquid storage cover 9, external contamination environment can not be flow to.
It should be noted that, during structural design, dredging bar 8 be avoided to interfere with valve plate 4, do not affect the keying of valve plate 4.
Wherein, described dredging bar 8 stretches into the front portion of one end in valve seat 3 for most advanced and sophisticated.Like this, can effectively insert dirt inside, dredge.
Butterfly valve provided by the present invention, only need control valve rod by spanner and rotate, and then change the aperture of valve plate, i.e. flow in adjustable valve, closed procedure is easy, and not easily leak, reliability is high, and solves butterfly valve blocking in prior art and be difficult to the problem of clearing up.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
