Preferably, the dish plate ontology is made of chassis and center disk body, the diameter of the center disk body from its surface to Chassis direction gradually incrementally makes its side form inclined-plane, and the maximum gauge of the center disk body is less than chassis diameter, the center The thickness of disk body is more than the thickness on chassis.
Preferably, the elastic telescopic device is spring, and the spring can by the chassis side of bolt and dish plate ontology Dismantling connection.
Preferably, the cross sectional shape of the positioning protrusion of the dish plate body edges side surface is T-shaped.
Preferably, the valve interior wall inlet is respectively arranged with a detachable anti-corrosion elastic packing with liquid outlet direction Circle.
Preferably, the sealing ring is higher than the valve interior wall between valve interior wall surface and 2 sealing rings and 2 sealing rings Seal groove is formed, the seal groove reaches the effect of high sealing with the mutual cooperation of the inclined-plane of the sealing ring on dish plate and center disk body Fruit.
Compared with prior art, the beneficial effects of the utility model are:Sealing performance is high, antiseptic property is good, extends butterfly valve Service life, the convenient, sealing ring of repair it is replaceable and in use due to close on elastic sealing ring on dish plate and valve body The tight fit of seal, as pipeline internal medium its sealing effect bigger to the pressure of butterfly valve is better.
Description of the drawings
Fig. 1 is the utility model structure chart;
Fig. 2 is the front view of the utility model dish plate;
Fig. 3 is the side view of the utility model dish plate;
In figure:1 valve rod, 2 valve bodies, 3 dish plates, 4 sealing rings, 5 seal grooves, 6 sealing rings, 7 springs, 8 bolts, 9 convexes Rise, 10 center disk bodies, 11 chassis.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole Embodiment.
A kind of butterfly valve of high sealing, including dish plate 3, valve body 2 and valve rod 1, the dish plate 3 includes dish plate ontology and is set to The detachable anti-corrosion elastic sealing ring 6 of dish plate body edges;The dish plate ontology outer edge surface is provided with elastic telescopic device, The elastic telescopic device is detachably connected with dish plate ontology, and the dish plate body edges side surface is provided with positioning protrusion 9, institute The position for stating positioning protrusion 9 is corresponding with elastic telescopic device;It is provided on the anti-corrosion elastic sealing ring and dish plate ontology side The groove that the positioning protrusion 9 of edge side surface matches.
The dish plate ontology is made of chassis 11 and center disk body 10, and the diameter of the center disk body 10 is from its surface bottom of to 11 direction of disk gradually incrementally makes its side form inclined-plane, and the maximum gauge of the center disk body 10 is less than 11 diameter of chassis, described The thickness of center disk body 10 is more than the thickness on chassis 11.
The elastic telescopic device is spring 7, and the spring 7 is removable by bolt 8 and 11 side of chassis of dish plate ontology Unload connection.
The cross sectional shape of the positioning protrusion 9 of the dish plate body edges side surface is T-shaped.
The 2 inner wall inlet of valve body is respectively arranged with a detachable anti-corrosion elastic seal ring 4 with liquid outlet direction.
The sealing ring 4 is formed higher than the valve interior wall between 2 inner wall surface of valve body and 2 sealing rings and 2 sealing rings Seal groove 5, the seal groove 5 reach the effect of high sealing with the mutual cooperation of the inclined-plane of the sealing ring 6 on dish plate 3 and center disk body 10 Fruit.
