Patent number: 9377115Abstract: A check valve for a spray nozzle including a tubular valve body, a shut-off member and a valve seat, wherein the shut-off member is mounted for movement at least in a longitudinal direction of the tubular valve body. The shut-off member is connected to the valve body by a corrugated tube disposed parallel to the longitudinal direction, wherein the shut-off member is biased toward the valve seat due to the spring effect of the corrugated tube. The check valve is suitable for use in, for example, descaling nozzles.Type: GrantFiled: May 24, 2012Date of Patent: June 28, 2016Assignee: LECHLER GMBHInventors: Juergen Frick, Boris Schmidt, Albert Fecht

Patent number: 8079534Abstract: The invention relates to a spray nozzle, particularly a high pressure nozzle, for descaling steel products, having a mouthpiece, which is provided with a discharge opening and a discharge chamber, which tapers towards the discharge opening. According to the invention the discharge opening spans a curved surface and a surface surrounding the discharge opening boundary at each point of said boundary strikes the discharge opening boundary at an angle between 65 and 95°, particularly 90° to the median longitudinal axis. Use e.g. for descaling nozzles.Type: GrantFiled: May 14, 2008Date of Patent: December 20, 2011Assignee: Lechler GmbHInventors: Albert Fecht, Juergen Frick, Boris Schmidt

Patent number: 6904953Abstract: A cooling arrangement for the rolling stand of a continuous casting system for heavy supports is provided with spraying nozzles which can be acted upon by cooling liquid and compressed air through supply pipes laid laterally in a longitudinal direction of the rolling stand. Only two supply pipes for cooling liquid and compressed air respectively are assigned to each side of the rolling stand. The supply pipes are laid parallel to one another and are equipped with connection flanges on which connection plates can be mounted in a simple manner and, in turn, are fixedly connected with spraying nozzles. This further development permits a simple mounting and demounting of the spraying nozzles and ensures a precise alignment of the spraying jets with respect to the billet to be processed.Type: GrantFiled: July 3, 2002Date of Patent: June 14, 2005Assignee: Lechler GmbHInventors: Juergen Frick, Roman Haap, Albert Fecht

Patent number: 6705538Abstract: A two-medium spraying nozzle is provided with a mixing chamber arranged in a housing and with one connection duct respectively leading into this mixing chamber for the feeding of a gaseous and of a liquid medium. A mouthpiece is connected behind the mixing chamber, in which mouthpiece a rotationally symmetrical central outlet opening is provided. In the bore of the mouthpiece, a swirl insert is arranged, and the outlet opening has a diameter which corresponds to no more than half the diameter of the bore of the mouthpiece. Such a two-medium spraying nozzle is unsusceptible to clogging and is particularly suitable for atomizing low-viscosity fluids for the cooling of continuous-casting systems for the production of steel.Type: GrantFiled: March 21, 2002Date of Patent: March 16, 2004Assignee: Lechler GmbH & Co. KGInventors: Albert Fecht, Ralf Hengstler
