Description

Drainage device

Technical Field

The utility model relates to a drainage device, and belongs to the technical field of pipeline drainage.

Background

After the valve is closed, the steam inside the steam pipeline does not flow back and forth, the temperature is reduced, and the steam is slowly condensed into water and accumulated in the pipeline. Condensation water is an important cause of decreasing the thermal efficiency of heat consuming equipment, causing equipment to malfunction and decreasing performance. The temperature of water and the temperature of steam are greatly different, the heat contained in the water are different, and if the pipeline contains condensed water, the heat exchange efficiency of the water is reduced. The condensed water in the pipe must be removed in time to improve heat exchange efficiency. The high-speed flowing steam pushes the accumulated condensed water to generate strong vibration and fluctuation on the pipe wall, the valve and the steam using equipment, and the phenomenon is called water hammer or water hammer. When the water hammer is strong, damage and destruction of a pipeline turning part or a valve can be caused, so that the whole system cannot safely operate. In addition, the condensed water of the steam pipe and oxygen in the air react chemically, which can cause corrosion to the steam pipe and equipment. The condensed water in the steam pipe must be timely drained.

The floating ball type automatic steam trap in the current market is unstable in floating of most floating balls, is unfavorable for the service life of the floating balls in the device, and is insensitive in opening and closing of the floating balls, so that the floating ball type automatic steam trap cannot be closed in time after draining water, or is not tight enough in closing, heat supply steam is leaked, energy is wasted, and normal operation of the device is unfavorable.

In summary, it is clear that the prior art has inconvenience and defects in practical use, so that improvement is needed.
