What is a siphon used for in a steam system?

To increase pressure
To protect the gauge
To separate water from steam
To regulate steam flow

The correct answer is: To protect the gauge

The primary function of a siphon in a steam system is to protect the gauge. A siphon is a device that uses the principle of fluid dynamics to create a barrier between the steam and the pressure gauge, ensuring that the high-temperature steam does not directly reach the gauge itself. This is crucial because excessive heat can damage the gauge and lead to inaccurate readings. By filling the siphon with water, it creates a cooling effect that allows the gauge to function properly, ensuring safety and reliability in monitoring the steam system. In essence, this setup helps maintain the integrity of the gauge, allowing it to accurately measure the pressure without being affected by the extreme conditions of the steam environment. The design of the siphon is such that it effectively isolates the steam pressure while still allowing for the necessary measurement of pressure levels, making it an essential component in maintaining overall system performance and safety.
