Abstract

The explosion protection and flame blowback protection valve is used in pipelines and the valve housing has a body moving in the direction of the valve axis. The valve body is held normally in an open position. In case of pressure fluctuation in the pipeline, this valve body is moved in the closing direction and disconnects the pipeline. The valve hollow body is plastics filled and it is symmetrical to a plane normal to the housing axis. The hollow body has a central guide sleeve. The end of the guide rod (5) is enclosed by a tubular hood (20) whose inner chamber (21) accommodates the catch for the valve body (7). This has a holding ring and an actuator stop on the free end of the guide sleeve. A spring is used as the holding element or the valve body within the inner chamber of the hood.
