T-fitting device e.g. for pipe installations with stand pipe for connection to medium-prominent main pipe, has flow switch in floor area of stand pipes underneath branch hole and connection point of T-fitting at main pipe

摘要

The T-fitting device has a flow switch (20) in the floor area of the stand pipes underneath a branch hole and the connection point (14) of the T- fitting at a main pipe. The flow switch is made from a tubular housing with an entrance and an exit port as well as of a body freely mobile inside the housing. In the range of the entrance opening, a stop is positioned for the body. The exit port inside of the housing has a tubing narrowing with a circular closure area. In the case of a conduit break or a leakage the closing bodies are carried forward by the current of the medium sealing and pushing it away. The tubular housing is directly or indirectly fastened to the tubing inner wall of the stand pipes (11) fastened with its tubing extent zone.
