Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valve assembly, and more specifically to a tool for assembling a butterfly valve. Background Art

[0002] The butterfly valve is also called butterfly valve for short. It refers to a valve whose closing part (valve disc or butterfly plate) is a disc, which rotates around the valve shaft to achieve opening and closing. It is mainly used for cutting and throttling in pipelines. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening, closing or regulating. The angle from full opening to full closing of the butterfly valve is usually less than 90°. The butterfly valve and butterfly stem themselves have no self-locking ability. In order to position the butterfly plate, a worm gear reducer should be installed on the valve stem. The use of a worm gear reducer can not only make the butterfly plate have self-locking ability and stop the butterfly plate at any position, but also improve the operating performance of the valve.

[0003] At present, butterfly valves are usually composed of structures such as valve body, valve stem, valve disc, sealing ring, etc. When assembling the valve body and valve stem, the staff usually hold the valve body and valve stem and manually insert the valve stem into the valve body for assembly. However, it is not convenient to limit and fix the valve body due to manual operation. At the same time, the gap between the socket of the valve body and the valve stem is relatively tight, so manual insertion is time-consuming and laborious, and sometimes a rubber hammer may be required for knocking for installation, which makes the assembly of the valve body and valve stem more troublesome and needs to be improved.
