Basic and Common Applications
Prevents leakage around a revolving shaft. Spring pressure holds nose of seal against shoulder on shaft. Another type rotates with shaft and seals against a stationary plate.
Convert pressure effects into controlled movement or force. Pressure may be applied inside the bellows or outside the bellows in a cup structure, the latter being preferred. The floating head is usually provided with a limit stop when overload protection is needed.
Provides a means to seal a flexible joint or mechanical movement of levers, linkage, etc. against leakage where the movement must be conveyed outside enclosure. “P” optimum position of pivot.
An aneroid assembly is a pressure motor where one side of a bellows assembly (inside the assembly illustrated) is evacuated to form a constant reference pressure against which the changing pressure on the other side is measured and used to produce predictable stroke. A spring for rate control and a stop to prevent excessive stroke from the resulting one atmosphere pressure differential usually are required.
This type of assembly is employed to absorb thermal or pressure expansion. With suitable heads, it may be used as a reservoir for a liquid or gas. Examples: Oil reservoir for electrical cable joint and thermal expansion compensators on oil-filled transformers.
Similar to pressure motors. Pressure supplied by a sealed fill of thermo-sensitive liquid or gas. Thermal effect may be received either on the bellows element direct or at a remote bulb for transmission through flexible tubing. Widely used to operate valves, switches, etc., in response to temperature changes.
Two bellows assemblies joined by a tube for hydraulic transmission of motion or power. With bellows system solid filled, linear motion of one bellows is transmitted instantly and in equal degree to remote bellows, both bellows being provided with limit stops when overload protection is needed.
Packless and leakless construction is used to absorb thermal expansion of pipe lines carrying steam, water, etc., or, to absorb vibration or provide a flexible connection.
Diagram illustrates packless valve construction. Same principle is used to seal steam movement or adjustment in many types of apparatus.
