  • Patent number: 11946553
    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.

  • Patent number: 11732808
    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.

  • Patent number: 10066752
    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.

  • Patent number: 9528612
    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).
