Abstract: 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.

Abstract: An explosion protection valve for decoupling system parts or workpieces 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 shifted from a defined open position into a sealing closed position in the event of a pressure or suction wave in the pipeline in at least one closing movement direction, 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, a sealing ring on the inner side of the housing, against which the closing body can be pressed in its closed position, and a receiving pocket, which is applied to the inner side of the housing and is preferably open counter to the closing movement direction (SB) of the closing body, for holding the sealing ring.

Abstract: 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.

Abstract: An explosion-proof sliding gate valve (1) for blocking a fluid flow (F) in a pipeline, which comprises: a sliding gate valve housing (2), a sealing plate (3) which is movably mounted in the slide gate valve housing (2) between an operating position (B) and a closed position (S), wherein in the closed position (S) the sealing plate (3) blocks the fluid flow (F), a mechanism for moving the sealing plate (3) from the operating position (B) into the closed position (S), and at least one deformation body (4) for damping movement of the sealing plate. The deformation body is arranged, according to the invention, at the side between sliding gate valve housing (2) and sealing plate (3).

Abstract: 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.

Abstract: Provided is a closing body mounted in a valve housing (4), the closing body being designed as a valve plate (9) and maintained in an operating position by a spring load action and/or by the effect of the fluid flow in the valve housing. The valve plate is hinged in the valve housing.

Abstract: 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.
