Description

Water hammer effect preventing device for external connection tube of large electric heater

Technical Field

The utility model relates to a water hammer effect preventing device of an external tube of a large-sized electric heater.

Background

When a plurality of large enterprises produce, the liquid needs to be heated, under the policy background of encouraging energy conservation and emission reduction, more and more enterprises discard the traditional energy heating method to heat the liquid, but adopt an electric heater to heat the liquid.

Because the U-shaped heating pipe is arranged inside the electric heater, the electric heater needs to be kept in a relatively stable state to run for a long time, however, in the case of a large-scale electric heater, a large amount of liquid is usually required to be filled.

When the liquid normally flows in the pipeline, the whole device is not influenced, but when the pipeline is opened or suddenly closed, a water hammer effect can be generated under the action of liquid inertia, impact can act on the electric heater along the pipeline, and certain damage can be caused to the U-shaped heating pipe inside for a long time, so that a device for preventing the water hammer effect of the external pipe of the large-sized electric heater is needed to protect the electric heater.
