摘要:
The invention suggests a spray element 20, in particular for die spraying devices 10, comprising supply means 42 for liquid working medium and, optionally, supply means 50 for control air, an atomizing device 78/80b connected with supply means 42 for working medium and a switch valve 62 controlable in dependence of pressure, said switch valve 62 having a flexibly biassed valve body 68 for alternatively establishing or interrupting the connection between the supply means 42 for working medium and the atomizing device 78/80b. In spray element 20, the valve body 68 is designed as having inherent flexible bias.

The invention refers to a spray element (320), espacially for die sprayers, comprising a feed line (342) for fluid working medium, a feed line (346) for working air, and an atomizing device (380). The atomizing device (380) is connected to the feed line (342) for working medium and to the feed line (346) for working air, has a pivoting nozzle element (380d), and operates according to the external mixing principle. A section of the feed line (342) for working medium leading to the pivoting nozzle element (380d) is designed as a section of flexible tubing (380d).

The invention relates to a spray tool (10) having a source (20, 21) for liquid working medium, a source (22) for control medium and a plurality of spray modules (14). Each spray module (14) has at least one feed (18, 19) for liquid working medium and at least one feed (38) for control medium, and comprises at least one spray element (16) for discharging liquid working medium. The spray modules (14) are combined to form a plurality of spray circuits (K 1 , K 2 , ...), the supply of control medium to which can be controlled independently of the supply of control medium to the other spray circuits. At least one spray circuit (K 1 , K 2 , ...) is assigned a distributor unit (28) which has a plurality of connection points (24) for connecting lines (26) which are guided freely to the feeds (38) of the spray modules (14) belonging to this spray circuit.

The invention suggests a spray element 20, in particular for die spraying devices 10, comprising supply means 42 for liquid working medium and, optionally, supply means 50 for control air, an atomizing device 78/80b connected with supply means 42 for working medium and a switch valve 62 controlable in dependence of pressure, said switch valve 62 having a flexibly biassed valve body 68 for alternatively establishing or interrupting the connection between the supply means 42 for working medium and the atomizing device 78/80b. In spray element 20, the valve body 68 is designed as having inherent flexible bias.
摘要:
The invention relates to a method and an apparatus (10) for automated servicing of a torch head (12) comprising at least one contact tip (20) and a nozzle (26) surrounding the at least one contact tip (20). In a first servicing device (32) the torch head (12) is contact-freely cleaned in an assembled state of said at least one contact tip (20) and said nozzle (26). A second servicing device (34) is used for applying a torch head treatment agent (42) to at least a portion of the surfaces of said at least one contact tip (20) and said nozzle (26). The operation of the first servicing device (32) and the second servicing device (34), respectively, is started by a control unit (50) after the torch head (12) has been transferred to a corresponding servicing position. Moreover the invention relates to the use of a liquid dispersion including between about 5 and about 50 percent-by-weight of boron nitride as a torch head treatment agent for servicing of a welding torch head.
