Description

Technical Field

[0001] The utility model relates to the technical field of butterfly plates, in particular to a butterfly plate. Background Art

[0002] Butterfly valve, also known as flap valve, is a simple regulating valve, which can also be used for the on-off control of low-pressure pipeline media. Butterfly valve is a valve with a disc or butterfly plate, which rotates around the valve shaft to open and close. It mainly plays the role of cutting off and throttling in pipelines.

[0003] The existing publication number CN211315158U discloses a butterfly plate of a butterfly valve, which relates to the field of butterfly valves, and includes a valve stem seat portion for penetrating the valve stem and wing plate portions on both sides of the valve stem seat portion, and a plurality of guide ribs are fixedly arranged on the wing plate portion, and the length direction of the guide ribs is perpendicular to the central axis of the valve stem seat portion, and the height direction of the guide ribs is perpendicular to the wing plate portion; the guide ribs are respectively connected to the valve stem seat portion and the wing plate portion as a whole; the guide ribs can play a role in guiding the medium or interfering with the vortex when the butterfly plate is opened, thereby reducing the scouring of the valve seat by the medium and enhancing the overall service life of the butterfly valve; the guide ribs have the function of reinforcing ribs, which can enhance the compressive strength and structural strength of the butterfly plate.

[0004] The existing technology uses the guide ribs to enhance the compressive strength and structural strength of the butterfly plate, thereby extending the service life of the valve plate to a certain extent; however, the edges of the valve plate are prone to wear during the opening and closing process of the valve plate, which affects the sealing of the valve plate. At this time, the valve plate needs to be replaced as a whole, which results in a high replacement cost. For this reason, we propose a butterfly plate. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a butterfly plate, including a valve plate body, an annular baffle is installed on the outer side of the valve plate body, and a pressure ring is installed on the annular baffle of the valve plate body for fixing the annular baffle; two shaft sleeves are installed on one side of the valve plate body, and a plurality of reinforcing ribs are installed on one side of the shaft sleeve of the valve plate body.

[0007] Preferably, the cross-section of the edge of the valve plate body is a stepped structure, and the pressure ring and the annular baffle are both installed at the stepped structure of the valve plate body.

[0008] Preferably, the pressure ring is fixed to the valve plate body by a plurality of fastening bolts, and the plurality of fastening bolts are evenly distributed in a ring shape.

[0009] Preferably, the annular baffle is formed by stacking a plurality of annular plates.

[0010] Preferably, the plurality of reinforcing ribs are symmetrically distributed on both sides of the two shaft sleeves, and the size of the reinforcing ribs in the middle of each side is larger than the size of the reinforcing ribs at the ends of each side.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The valve plate body is located at the annular baffle and is equipped with a pressure ring to fix the annular baffle. The annular baffle is composed of multiple annular plates stacked together. After a period of use, the worn baffle can be replaced without replacing the entire valve plate, thereby reducing the replacement cost. The undamaged annular plate does not need to be replaced, and only the damaged one needs to be replaced, thereby further reducing the replacement cost.

[0014] 2. The reinforcing ribs enhance the compressive performance of the valve plate. Multiple reinforcing ribs are symmetrically distributed on both sides of the two sleeves. The size of the reinforcing ribs in the middle of each side is larger than the size of the reinforcing ribs at the ends of each side, mainly to adapt to the size of the valve plate, thereby achieving uniform reinforcement of the strength of the valve plate; both ends of the reinforcing ribs adopt an arc structure, and the arc shape mainly plays a better role in guiding flow.
