The cylinder should be placed on the flange, especially when used in combination with a butterfly valve. The cylinder is installed on the butterfly valve through a flange to ensure its stability and reliability. The specific reasons are as follows:
Ensure tight connection: By adding gaskets on the flange, the gaps between the contact surfaces can be filled to prevent gas leakage and ensure the normal operation of the cylinder.
Prevent gas leakage: Gaskets can prevent gas from leaking out of the gaps in the contact surface, avoid affecting the working efficiency of the cylinder, and prevent safety hazards.
Compensating for surface unevenness: Industrial equipment may experience wear and deformation during use, resulting in uneven surfaces. Gaskets can compensate for these unevenness and improve the tightness of the connection.
Key points for selecting gaskets
Choosing the appropriate gasket is crucial for the installation of the cylinder. Here are some key selection points:
Material selection: The material of the gasket should be suitable for its working environment. Common materials include metal, rubber, plastic, non-metallic fibers, etc. Choosing appropriate materials can enhance sealing, high temperature resistance, and chemical corrosion resistance.
Thickness selection: The thickness of the gasket should be moderate. If it is too thin, it cannot fill the surface gaps, and if it is too thick, it will increase the deformation of the contact surface.
Standard compliance: The shape and specifications of the gasket should comply with relevant standards to ensure its suitability for specific butterfly valve and cylinder models.
