Description

Technical Field

[0001] The utility model relates to the technical field of wafer-type butterfly valves, in particular to a central lug wafer-type butterfly valve with a detachable sealing ring. Background Art

[0002] The butterfly plate of the wafer butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0°-90°, which can play the role of flow regulation. When the butterfly plate rotates to 90°, the valve reaches the maximum opening. The wafer butterfly valve has a simple structure, small size, and light weight. It is composed of only a few parts, and it can be quickly opened and closed by rotating 90°. It is easy to operate. At the same time, the valve has good fluid control characteristics;

[0003] In the prior art, a sealing rubber is fixedly mounted on the inner surface of the connecting ring of the lug-type butterfly valve. The long-term rotation of the butterfly valve will wear the rubber surface. Now the sealing rubber ring is difficult to disassemble and replace, resulting in a reduction in the service life of the lug-type butterfly valve. Utility Model Content

[0032] In this embodiment, the side wall of the limit plate 411 is arranged in contact with the side wall of the wafer-type butterfly valve body 1, and there are two circular blocks 413. The shapes and sizes of the two circular blocks 413 are equal, and the two circular blocks 413 are symmetrically arranged relative to the middle surface of the wafer-type butterfly valve body 1 in the front-to-back direction.

[0033] Example 2

[0034] On the basis of Example 1, a preferred embodiment of a center-type lug-to-wafer butterfly valve with a detachable sealing ring provided by the utility model is as follows: Figures 1 to 4 As shown: the stabilizing mechanism 42 includes a connecting seat 424, which is fixedly mounted on the side wall of the wafer-type butterfly valve body 1, and a long rod 423 is fixedly mounted on the side wall of the connecting seat 424, and a threaded rod 422 is fixedly mounted on the other end of the long rod 423, and a nut 421 is threadedly mounted on the side wall of the threaded rod 422.
