摘要： An explosion-proof valve (1), particularly a flap valve (1), for interrupting a flow of fluid (F), particularly in a pipeline, and comprising a valve housing (3) that has a passage opening (4) for the passage of the flow of fluid (F), and a valve seat (5) arranged at the passage opening (4), as well as a closing element (6), particularly a flap plate (6), which comprises a sealing surface (9) and lies with the sealing surface (9) against a valve seat (5) when in a closing position. The closing element (6) is moveably mounted on a bearing (17, 17′) in the valve housing (3). The bearing (17, 17′) of the closing element (6) is designed such that the closing element (6) can be moved, in a closing direction, out of the operating position and into the closing position by rotational and linear movement.

摘要： Disclosed is an explosion protection valve comprising a closing member (4) which is movable inside a housing (2), is guided along a guide bar (3), and can be displaced in a moving direction from a predefined open position into a sealing closed position in case of a shock wave or suction wave. The explosion protection valve further comprises a spring arrangement that is effectively connected to the closing member (4) in order to maintain the open position on the guide bar (3). Said spring arrangement is provided with a first spring element (5, 5′) and a second spring element (6, 6′) in relation to the respective moving direction. The spring elements are disposed such that the second spring element (6, 6′) can be impinged upon only following a predetermined spring travel (a) when the closing member (4) is displaced into the closed position.

摘要： The invention relates to a closing body (3) which is mounted in a housing (2) in such a way that it can be axially displaced and can be pressed out of an opening position against a valve seat (4) into a closing position. Said closing body (3) is rotationally symmetrical and comprises, on its outer diameter (D1) in relation to its cross-section, two outer wall sections (5, 5′) which meet at an angle of less than 180°. In this way, a surrounding interference edge (26) is formed, favouring turbulence in the flow and thus a rapid increase in the dynamic pressure. When the closing body is embodied as a hollow body, a spring action also occurs, damping the closing movement.
