摘要

The assembly is formed in the path distance between a supply- and return line of a remote or local heating pipe, and is connected with the pipe through two bends (3) welded at 90 degrees. A pipe fitting is provided according to the distance of the pipe line and two welded bends, where the pipe fitting and the bends are arranged in the same dimension as of the incoming pipe route. Two three-fourth inch ventilation pipes (5) are located at a certain distance on the assembly, where the vent pipe is arranged before an orifice (8). The orifice and a baffle plate (9) are located in the pipe fitting.
