[0002] Low-torque butterfly valve refers to a type of butterfly valve designed to reduce the torque required for butterfly valve operation. In the field of industry and fluid control, butterfly valve is a commonly used valve type used to control the flow of fluid media. Traditional butterfly valves may require a large torque to open or close, while butterfly valves designed with low torque optimize the structure, materials and processes to make the torque required for operation smaller, thereby improving the convenience and efficiency of operation. The production of butterfly valves requires the use of butterfly valve molds.

[0003] Based on the above, the inventors have found the following problems: when the existing butterfly valve mold is in use, when the lost foam is made, most of them need to manually pull the mold apart and then remove the model, which is quite troublesome.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a low-torque butterfly valve mold is provided to achieve a more practical purpose. Utility Model Content
