Pressure relief valve, particularly for limiting fluid pressure in distribution pipe, has radial outflow channel connected with bore portion via axial channel which is formed as axial bore

摘要

The pressure relief valve has radial outflow channel (42) is connected with a bore portion (22c) via an axial channel (46). A valve housing (20) with a through hole formed by three bore portions. The diameter of the third bore portion (22c) is greater than the diameter of the latter bore portion (22b). The axial channel is formed as an axial bore, which run from the third bore portion to the latter bore portion through a transition.
