Abstract
A valve (1) for an explosion protection apparatus comprises a pipe element having a pipe wall (11). Two slides (15, 15') can be pushed from the outside into the pipe element, through in each case one opening (111, 111') in the pipe wall (11). An expandable diaphragm (14) is arranged on the inside of the pipe wall (11) and forms an inner pipe which can be closed by means of the slide (15, 15') by mutually opposite diaphragm regions being pressed against one another. The expandable diaphragm which forms an inner pipe does not provide any accretion points for solid particles of product-loaded gas flow to collect on.
