Description

Technical Field

[0001] The utility model relates to the field of thermal insulation pipes, in particular to a lower drain device for prefabricated thermal insulation pipes. Background Art

[0002] The prefabricated insulated pipe consists of three parts: a working pipe, an outer protective layer and an insulation layer. The steam trap is an automatic drainer that can drain water and block air, thereby discharging condensate in the conveying equipment and blocking steam in the insulation pipe, thereby improving the overall performance of the insulation pipe. During the drainage process, a large amount of condensate will be generated in the steam pipe. If it is not removed in time, water hammer will often occur, causing pipe vibration and damage to the compensator and weak links of the pipe. In order to ensure safe operation in the pipe network, a drain device is generally set on the surface of the steam pipe, including an upper drain device and a lower drain device. The drain pipe of the lower drain device currently installed in the steam pipe is connected to the outer protective steel pipe, and the connection is not stable enough. In addition, if there are impurities in the pipe, when they are concentrated in the sump, they cannot be effectively cleaned from the outside, and when there are too many impurities, it is easy to cause blockage of the drain pipe. Therefore, a lower drain device for a prefabricated insulated pipe is proposed. Utility Model Content
