Description

Technical Field

[0002] A high-pressure heater is a device that utilizes partial exhaust of a steam turbine to heat feed water. Various high-pressure heater drain level control auxiliary devices have been proposed in the prior art. For example, a high-pressure heater drain level control auxiliary device is proposed in Chinese utility model patent publication number CN220269653U. The high-pressure heater drain level control auxiliary device is provided with a first liquid level control mechanism. When the liquid level sensor fails, the threaded rod is rotated to drive the support plate and the blocking block to move up and down along the threaded rod and the second guide rod, so that the distance between the blocking block and the float can be adjusted. The larger the distance, the less water can be injected, and the smaller the distance, the more water can be injected. Then, water is injected from the water inlet, and the water pushes the float upward. When it finally reaches a certain amount, the blocking block will block the water inlet, so that the control of the drain level of the high-pressure heater body can be completed in time, and the efficiency of the high-pressure heater body in heating water will not be affected.
