Structural representation when Fig. 2 is valve plate unlatching shown in Figure 1;
Fig. 3 is the structural representation of flow control device shown in Figure 1.
Embodiment
Below by embodiment and accompanying drawing, the technical solution of the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of preferred implementation of the utility model; Fig. 2 is the structural representation of the valve plate of this preferred implementation when opening.By Fig. 1 and in conjunction with Fig. 2 as can be known, this butterfly valve is mainly by formations such as valve body 10, ceramic valve plate 11, handle 15, flow control device 9, teflon rubber valve seat 1, valve rods (7,14), wherein valve body 10 vertically is provided with axis hole 70, cover has valve rod (valve rod is made of upper valve rod 7 and lower valve rod 14) in the axis hole, the valve body middle part is provided with the circular channel 2 that is connected with pipeline, be provided with teflon rubber valve seat 1 in the circular channel 2, valve plate 11 is arranged in the teflon rubber valve seat 1 and with valve rod and is connected.
Valve plate is take silicon nitride ceramics as material, utilizes accurate control process forming sintering to make, and wear resistance, anti-corrosive properties and sealing that it has improved valve products have greatly prolonged working life of valve.
The end of upper valve rod 7 is square plush coppers 6, and the center of square plush copper 6 is provided with positioning shaft 5, and the end of lower valve rod 14 is provided with circular positioning shaft 13.The first half in valve plate 11 fronts is provided with pole socket 4, the Lower Half of its reverse side is provided with the lower pole socket 12 coaxial with upper pole socket 4, because square plush copper 6 and positioning shaft 5 thereof are complementary with the shape of upper pole socket 4 inner groovies and positioning hole, therefore can enter easily in the pole socket 4, with the rotation of control valve plate 11.Circular positioning shaft 13 is complementary with the positioning hole of lower pole socket 12, enters in the lower pole socket 12, so that the rotating fulcrum of valve plate 11 to be provided.
When valve plate 11 with after upper lower valve rod is connected, this valve plate 11 just is arranged in the circular channel 2 of valve body 10 in the inclination mode.Take valve rod center line 8 as baseline, the longitudinal axis of above-mentioned valve plate 11 3 is 16～27 ° with the optimized angle of the inclined angle alpha that valve rod center line 8 consists of, by facts have proved, when inclined angle alpha in this scope during value, its valve plate 11 rotates, sealability is best.
Be provided with the hollow stainless steel coil 100 of O shape in the teflon rubber valve seat, valve plate 11 shapes of the shape of the sealing surface of teflon rubber valve seat when closing fit like a glove.Because teflon rubber, shows inertia, energy strong alkali-acid resistance, water and various organic solvent to most of chemicalss and solvent, does not adhere to any material.Hollow stainless steel coil can improve valve seat intensity and sealability after the combination of teflon rubber, reduce material consumption, reduce valve seat construction weight and cost.Application in practice shows, this valve seat has possessed high lubricated, the advantage such as the life-span is long, and the serviceability temperature scope is (serviceability temperature is-196 ℃～250 ℃) extensively, and is corrosion-resistant.
Because valve plate 11 tilts, the sealing surface of valve plate 11 produced the effect that gradually goes out to break away from or be fade-in compression with respect to the sealing surface of teflon rubber valve seat 1 when it opened and closed.So in the moment that valve plate 11 is opened, the sealing surface of its valve plate 11 sealing surfaces and teflon rubber valve seat 1 can disengage immediately; And in the moment that valve plate 11 is closed, valve plate 11 sealing surfaces contact and compress again the sealing surface of teflon rubber valve seat 1 immediately, so valve plate 11 basic not scraping and excessive compression phenomenon in opening-closing process.
Fig. 3 is the structural representation of flow control device 9.As shown in the figure, limit stoper is made of sector 91, bumper bar 17, handle 15.Sector 91 is fixed in valve body 10 tops, and sector 91 covering of the fan edges are provided with a toothrow groove 19, and sector 91 covering of the fan two ends are provided with baffle plate 20.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection domain of the present utility model to any simple modification, equivalent variations and modification that above embodiment does.
