Abstract:
A refractory nozzle is provided for a metallurgical vessel, in particular for steel melts, wherein the nozzle has a flow-through opening with an upper end, a lower end, and an inner wall laterally enclosing the flow-through opening. In order to improve known discharge nozzles, in particular with regard to their thermal shock resistance, a heater and/or a thermal insulating material, that dissolves or bums upon contact with fluid steel, is arranged along the inner wall in the flow-through opening.
Abstract:
A sealing element is fitted between the outside periphery of the magnet armature and the inside periphery of the valve housing and, parallel to the sealing element, an orifice is fitted in the armature, thereby establishing a permanent pressure fluid connection between the pressure fluid chamber disposed inside the magnet armature and the pressure fluid chamber disposed outside the armature.
Abstract:
This invention relates to a solenoid valve where a volume governor which governs the hydraulic flow is inserted coaxially to the valve closure member into the valve accommodating body of the valve. The volume governor is integrated by way of series connection between the first pressure medium connection, emanating from a pressure medium source, and the valve closure member. A reduction of the valve operating noises is ensured with a smallest-requirement-answering structural size, thus the control noises being prevented from propagating over the entire connected system.
Abstract:
The magnetic coil (1) of an electromagnetic valve is held inside a yoke plate (2) by means of an appropriate component (3) and arranged inside the yoke plate (2) in a manner so that it can be rotated arbitrarily about the longitudinal axis of the valve housing (4).
