摘要： The invention concerns a bottoms drainage valve, designed in particular for enamelled containers used in the chemical industry which must satisfy stringent requirements in terms of resistance, easy maintenance and operational safety. Said bottoms drainage valve comprises a flange portion consisting of a cylindrical section forming the valve seat head and capable of being inserted into an annular constriction of the container, as well as a shoulder extending transversely to said cylindrical section and enables the flange portion to be connected to said container. The invention is characterized in that said flange portion is conically tapered towards its upper end and in that a cylindrical sealing module whereof the upper part includes an elastically/plastically deformable reinforced annular sealing zone is interposed in the annular constricted zone, between the flange part and the container wall.

摘要： Disclosed is a fire-protecting pipe connector for pipes made especially of fire-resistant material. Said fire-protecting pipe connector comprises a connection piece (30) made of an elastic material that can be connected to the first end piece in a tightly sealing manner, a connection piece (32) made of an elastic material, an intermediate piece (60) which is sealingly connected to the first and the second connection piece therebetween and is made of a material that is resistant to a medium conducted by the pipes when the material is not affected by heat generated by a fire while being non-rigid under the effect of heat generated by a fire, a support (84) which is made of a material that expands under the effect of heat generated by a fire and forms a fire-resistant, rigid member, and a support collar (120) made of a heat-conducting fire-resistant material.

摘要： The invention relates to a gate valve comprising a housing (10, 16) that is especially made at least in part of cast iron and is provided with a passage (11) which connects an inlet port (12) to an outlet port (14) for a fluid flowing in a specific direction of flow. Said gate valve further comprises a closing plunger (20) that is movable between a blocking position in which the passage is blocked and an open position in which the passage is open, and a spindle (21), said spindle (21) being coupled to the closing plunger (21) while being mounted in the housing by means of a bearing system (50) so as to be rotatable about a spindle axis. The bearing system (50) and/or the closing plunger (20) is/are embodied as several pieces. The closing plunger and/or the bearing system is/are provided with two or more components (22, 24, 60, 70) that are disposed one behind another in the direction of the spindle axis in such a way that a plane is created which extends perpendicular to the spindle axis while intersecting only one of said components.
