Embodiment Construction

[0013] figure 1 As a preferred embodiment of the present invention, the present invention will be further described below in conjunction with the accompanying drawings.

[0014] according to figure 1 , the butterfly plate of the butterfly valve, including a valve body 1, is characterized in that: it also includes an elliptical butterfly plate 2 placed in the valve body 1, the valve body 1 is circular, and the length of the major axis of the ellipse is equal to that of the valve body 1 diameter, the major axis of the ellipse is parallel to the diameter direction of the valve body 1 .

[0015] No matter how the butterfly plate 2 is rotated, there is always water flowing through it; by rotating the butterfly plate 2, the amount of water can be adjusted; the material of the butterfly plate 2 is saved.

[0016] The above embodiments do not limit the present invention in any form, and all technical solutions obtained by means of equivalent replacement or equivalent transformation ...

Abstract

The invention belongs to the field of butterfly valves, and in particular to a butterfly plate of a butterfly valve. The butterfly plate of the butterfly valve comprises a valve body and is characterized by further comprising an elliptical butterfly plate placed in the valve body which is circular. The length of the elliptical major axis is equal to the diameter of the valve body, and the elliptical major axis is parallel to the diameter of the valve body. The butterfly plate of the butterfly valve provided by the invention has the beneficial effects that no matter how the butterfly plate is rotated, water flows through; the water quantity can be adjusted by rotating the butterfly plate; and materials of the butterfly plate are saved.

Description

[0001] technical field [0002] The invention belongs to the field of butterfly valves, and in particular relates to a butterfly plate of a butterfly valve. [0003] Background technique [0004] At present, the butterfly plate of the butterfly valve is usually circular, and the opening and closing of the valve is realized by rotation. For the main valve of domestic water, the main valve can usually be rotated to adjust the water flow. When adjusting, the water may not flow at all, that is, the valve is completely closed, resulting in no water. [0005] Contents of the invention [0006] The object of the present invention is to overcome the above disadvantages and provide a butterfly plate of a butterfly valve that always has water flowing through it and can adjust the amount of water. [0007] In order to achieve the above object, the technical solution adopted in the present invention is: the butterfly plate of the butterfly valve, including the valve body, is chara...
