摘要：
An explosion protection valve for decoupling system parts or workpieces, in particular for the installation in a pipeline, comprising
a housing,
a closing body which is axially guided inside the housing on a guide rod and can be displaced from a defined open position in the event of one of the group comprising a pressure and suction wave in the pipeline in at least one closing movement direction into a sealing closed position in which the closing body can be fixed by means of a locking device,
a spring assembly, which is in operative connection to the closing body, on the guide rod for holding the closing body in the open position,
bearing assemblies each carrying the end of the guide rod, which are each connected to the housing by means of at least one suspension cross-member, and
a bearing arrangement, which is subject to play, of the at least one suspension cross-member in a receiving opening on the housing.
