Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valve plate grinding, and specifically, to an outer circle grinding device for a butterfly valve plate. Background Art

[0002] A butterfly valve, also called a flap valve, is a simple regulating valve that can be used for the on-off control of a medium in a low-pressure pipeline. The butterfly valve refers to a valve whose closing member (valve flap or butterfly plate) is a disc and rotates around the valve shaft to achieve opening and closing. Currently, an urgent problem to be solved is how to grind the outer circle of the valve plate during the production process of the butterfly valve and how to avoid the dispersion of grinding dust during the grinding process.

[0003] After retrieval, the patent with the publication number CN220839283U discloses an outer circle grinding device for a butterfly valve plate, which includes a base, a support column located at the top of the base, a bearing plate rotatably installed at the top of the support column, and a driving component located above the bearing plate. Multiple grinding components arranged in a circular array along the support column are provided on the base; each grinding component includes a slider slidably installed on the base, a column vertically installed on the top of the slider, and a grinding sleeve sleeved on the column. A sliding groove for the slider to slide is formed on the base, and a spring for driving the slider to approach the bearing plate is provided in the sliding groove. In this case, multiple grinding components arranged in a circular array along the support column are provided on the base, and the grinding components are slidably arranged on the base and are driven by the spring to approach the bearing plate. After the valve plate is placed on the bearing plate, the valve plate can be automatically adjusted by multiple grinding components to make the valve plate coaxial with the bearing plate, ensuring the grinding accuracy and improving the grinding efficiency.

[0004] During the process of grinding the valve plate by the above-mentioned outer circle grinding device for a butterfly valve plate using the grinding sleeve, a large amount of dust will be generated on the outer circle part of the valve plate, and the device is not provided with a design for dust collection. Therefore, this design defect will cause the dust to disperse in the ambient air, which is not only difficult to clean, but also poses a health hazard when inhaled by workers.
