Description

Technical Field

[0001] The utility model belongs to the technical field of stop valve raw material processing, in particular to a raw material cutting mechanism for stop valve processing. Background Art

[0002] The stop valve is a tool that relies on the pressure of the valve stem to make the valve disc sealing surface fit tightly with the valve seat sealing surface to prevent the flow of medium. It is a forced sealing valve and is mainly installed on high-temperature and high-pressure steam and water pipelines with a diameter of ≤100mm in the power plant piping system.

[0003] When cutting the stop valve, the raw material itself is too long, so it needs to be compressed before cutting to ensure that its size meets the use requirements. However, companies generally only fix the head and tail of the raw material before cutting. However, the cutting is often unstable due to the gap generated after cutting, which affects the subsequent cutting accuracy. Utility Model Content
