[0033] Combine below Figure 1-7 To illustrate this embodiment, the butterfly valve valve further includes a rubber column 109 and an arc-shaped rubber sheet 403. The left and right ends of the upper side of the disc 402 are provided with an arc-shaped rubber sheet 403, and the upper end of the card cylinder 108 is fixedly connected to a rubber column 109. , when the clamp cylinder 108 leaves the arc-shaped notch 401 , the rubber column 109 presses against the outside of one of the arc-shaped rubber sheets 403 . When the butterfly plate 3 is in the open state, the rubber column 109 is pressed against the outside of one of the arc-shaped rubber sheets 403, and there is friction between the rubber column 109 and the arc-shaped rubber sheet 403, which is convenient for fixing the butterfly plate 3 at this position, so that the valve A fixed flow rate is obtained so that the butterfly plate 3 will not rotate arbitrarily.

Abstract
The invention relates to a valve and particularly relates to a butterfly valve capable of realizing multiple regulation. The butterfly valve comprises a valve housing, a butterfly plate, a rectangularhole, a lower shaft, a rubber ring, an upper shaft, a lifting bar, a connecting column and a rectangular baffle. The butterfly valve provided by the invention adopts a multiple flow rate regulation way and meets various requirements on flow rate. The periphery of the butterfly plate is provided with the rubber ring; the lower end of the butterfly plate is fixedly connected with the lower shaft; the butterfly plate is provided with the rectangular hole which is through from the left part to the right part of the rectangular hole; the upper end of the butterfly plate is fixedly connected with the upper shaft; the upper shaft is of a hollow structure; the lifting bar is vertically and slidably connected to the upper shaft; the lower part of the lifting bar enters the rectangular hole after penetrating through the butterfly plate; the lower end of the lifting bar is fixedly connected with a connecting column; the left end of the connecting column is fixedly connected with a rectangular baffle; the rectangular baffle clings to the left side of the butterfly plate; when moving up and down, the lifting bar is used for driving the rectangular baffle to open or close the rectangular hole;the butterfly plate is positioned inside the valve housing; and the upper shaft and lower shaft are correspondingly rotationally connected to the upper end and the lower end of the valve housing.
Description
technical field [0001] The invention relates to a valve, more specifically a multi-adjustable butterfly valve. Background technique [0002] Application No. CN99208927.1 discloses anti-sediment butterfly valve, anti-sediment butterfly valve, the valve plate of the valve is located on one side of the valve shaft, the valve plate is fixed with a sealing ring and a pressure plate, and an adjusting screw is installed on the valve plate , There is a spacer between the valve shaft and the valve body, a water outlet is opened on the valve body, and an oil cup is installed. This butterfly valve can prevent the conveyed liquid and sand from penetrating into the bearing, and prevent the bearing from being corroded and stuck. , prolong life, reduce cost, facilitate maintenance, and are suitable for use on pipelines transporting media with large sediment content. However, this anti-sediment butterfly valve does not have multiple flow adjustment methods and cannot meet various needs for...
