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.
