What is the purpose of a siphon in a boiler system?

The function of a siphon in a boiler system is crucial for its safe operation. Specifically, a siphon is designed to create a water seal that helps prevent live steam from coming into direct contact with components such as gauges or other equipment that may not be able to withstand high temperatures or pressures. This water seal is essential because it acts as a barrier, minimizing the risk of steam or hot water escaping, which could lead to safety hazards or damage to equipment.

In this context, the siphon ensures that the pressure and temperature readings are both accurate and safe for operation. By maintaining this water barrier, it protects sensitive parts of the system from the adverse effects of high heat and pressure, fulfilling a critical safety role within the boiler system.
