Detailed Description

The technical solution of the present invention is further explained by the accompanying drawings and examples.

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which the invention belongs. The use of "first," "second," and similar terms in the description herein do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

As shown in the figure, the highly sealed butterfly valve comprises a valve body 1 and a valve plate 2 arranged on the inner side of the valve body 1, wherein the valve body 1 provides support for the valve plate 2. Valve plate 2 is structure as an organic whole, and the upper and lower side of its one side all is equipped with fixed section of thick bamboo 3, and the top of valve plate 2 is equipped with the rotary rod 11 that runs through fixed section of thick bamboo 3, can realize the rotation of valve plate 2 through rotary rod 11.

The outside of a fixed section of thick bamboo 3 is equipped with the strengthening rib 13 of being connected with valve plate 2, improves a fixed section of thick bamboo 3's bearing strength, guarantees that rotary rod 11 drives the steady rotation of valve plate 2. The other side of valve plate 2 is equipped with horizontally water conservancy diversion strip 4, realizes the direction flow of rivers through water conservancy diversion strip 4, the switching of the valve plate 2 of being convenient for. The upper side and the lower side of the rotating rod 11 are provided with sealing gaskets 12 positioned on the valve body 1, so that the sealing performance of the rotating rod 11 is ensured. The valve body 1 is provided with an in-place block 14 connected with the side surface of the valve plate 2, so that when the valve plate 2 is turned over, the in-place block 14 realizes the positioning of the valve plate 2.

Both sides of valve plate 2 all are equipped with annular sealing washer 5 and fixed plate 6, and sealing washer 5, fixed plate 6 pass through bolted connection on valve plate 2, guarantee the stable connection of sealing washer 5 and fixed plate 6. The surface of the sealing ring 5 is provided with a corrugated raised structure, so that the sealing effect of the sealing ring 5 is improved. The inner side of the sealing ring 5 is provided with an inner cavity 7 and an outer cavity 8 which are communicated, and the two sides of the sealing ring 5 are symmetrically provided with an inlet 9 connected with the inner cavity 7 and an outlet 10 connected with the outer cavity 8. The inner cavity 7 and the outer cavity 8 are positioned at two sides of the sealing ring 5, so that the stable support of the sealing ring 5 is ensured.

When the valve plate 2 is opened, water flows in from the inlet 9 and flows to the outlet 10 through the inner cavity 7 and the outer cavity 8, and expansion of the sealing ring 5 is achieved. When the valve plate 2 is closed, the water flow is partially discharged under extrusion, and partially remains in the inner cavity 7 and the outer cavity 8, so that the stable sealing of the sealing ring 5 on the pipeline is ensured.
