Gasket locating arrangements

a gasket and locating technology, applied in the direction of mechanical equipment, lighting and heating equipment, laminated elements, etc., can solve the problems of difficult cleaning and spot cleaning, requiring a large thickness of the plate, and difficult to remove the dowel pins easily, so as to achieve a little or minimal contact

AI Technical Summary

Benefits of technology

The solution enables precise location and secure attachment of gaskets, even for complex shapes, reducing crevice formation and enhancing cleaning and corrosion resistance, while allowing for flat surfaces and easy handling during assembly.

Problems solved by technology

This can be a problem during assembly of complex shaped gaskets, or where the gasket is hidden during assembly, or where there are no means to locate the gasket by its edges.
A restriction is that for the interference fitted dowel pins it requires enough thickness of the plate.
Another restriction is that it does not easily allow for removal of the dowel pins and there will always be crevices in the interference fit for the dowel pins which are difficult to clean and spot for corrosion.

Embodiment Construction

[0031]FIG. 1 illustrates a gasket 1 located with a pin 2 on to all-through hole 3. In this figure the pin is a headed pin or a headed dowel pin. The head 4 is fitted into countersunk area 5, see FIG. 2. Since the hole of the gasket is fitting pin 2, then the gasket material will follow the pin down into countersunk area 5. This solution does locate and attach the gasket to one of the surfaces during assembly. All-through hole 3 have a countersunk area for the head of pin 2, thus the head “disappears” in the surface, which surface should still remain flat. All-through hole 3 allows easy removal of pins 2 when disassemble the reactor or flow module. Another advantage of all-through holes is that the holes will be easily cleaned. FIG. 3 also illustrates that the gasket 1 has been compressed when the reactor or the flow module is assembled, and the thickness is less than that of an unused gasket.

[0032]FIG. 4 shows how the gasket 1 is located onto protruded pin 7 or onto integrated pin 7...

Abstract

The present invention relates to a gasket locating arrangement for a flow module, preferably plate reactor, comprising a gasket, locating means, a channel in a channel plate, a barrier plate, wherein the gasket consists of a sheet of soft gasket material, and said sheet has a cut through pattern corresponding to the channel in the channel plate. The present invention relates further to a use of the gasket location arrangement and also to a flow module, preferably a plate reactor, which comprises one or more gasket locating arrangements according to the invention, and one or more heat transfer means for heat transfer to and from the channel, and wherein each channel plate has one or more inlets, preferably two inlets, to the channel, and one outlet from the channel.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation application and claims priority benefit of commonly owned and U.S. patent application Ser. No. 13 / 504,555, filed Jul. 10, 2012, which is a national stage application of PCT Application No. PCT / EP2010 / 066178, filed Oct. 26, 2010, which claims priority to Swedish Patent Application No. SE 09174589.3, filed Oct. 30, 2009, which are hereby incorporated by reference in their entireties.FIELD OF THE INVENTION[0002]The present invention relates to a gasket locating arrangement, a use of the gasket locating arrangements in a flow module, and a flow module, preferably a plate reactor.BACKGROUND OF THE INVENTION[0003]Thin, planar gaskets can be used in applications where two flat surfaces are clamped together to seal off an interior chamber or flow path to an exterior space. In some applications, the gaskets are located coincident with the shape of the flat sealing surfaces. In other applications, the gaskets are ...
