Vacuum valve design considerations and structural calculation method

Vacuum valve is an important component of the vacuum system. The size of the conductance of a valve forming part of a pipeline is an important performance parameter. For valves that operate primarily as a gas switch, the seal performance of the valve plate closure is also one of the key performance parameters. The sealing performance is measured by its leak rate. For the main valve used to regulate the size of the air flow, to adjust the accuracy and scope of gas flow, it is an important performance parameters. For the all-metal ultra-high vacuum valve, each shutdown is stable performance? Whether the service life is long? Is its main performance indicators.

Rebar Steel Cutting Machine

The steel bar cutting machine is a tool used for shearing steel bars, with automatic steel bar cutting machines and semi-automatic steel bar cutting machines. It is mainly used for the fixed length cutting of steel bars in civil engineering, and is an indispensable equipment for the processing of steel bars. Compared with other cutting equipment, it has the advantages of light weight, low energy consumption, reliable operation and high efficiency. Therefore, it has been widely used in the field of mechanical processing and played an important role in the national economic construction process.
