Description

The The invention relates to an arrangement for complete thermal insulation of pipe sections including the associated Fittings / valve assemblies with a double-shell construction of the thermal insulation and with openings for the reading of measuring instruments the fittings / valve assemblies.

thermal insulation on pipelines or pipe sections are well known. Also Such solutions, in addition to the isolation of pipe sections In addition, fittings and valve assemblies are used to prevent heat loss to enclose are known.

So will in the DE 10 2005 014 869 A1 described a thermal insulation of one or more parts housing of heat-insulating material, which provided by means of recesses and openings for receiving regulator or regulator parts, are suitable to include them without further brackets in the heat insulation.

Such Elements usually have a bivalve structure, with the both parts of the thermal insulation via clamping elements be connected with counter elements.

disadvantage This arrangement are in the heat-insulating material arranged clamping elements whose structure in the manufacture of Half shells are relatively expensive.

task The invention is based on this prior art double-shell heat-insulating housing made of one to provide high quality insulation material, which is suitable in a simple and cost-effective way or valve assemblies effectively against heat radiation protect, openings for measuring instruments to consider and in particular a simple and effective to enable effective assembly of the insulation.

According to the invention solved the problem by the half shells of the heat-insulating Housing made of a rigid PU foam. The PU rigid foam allows a very durable, stable and high quality Isolation of the fittings.

In These shells are each firmly foamed connector incorporated. In a half shell this is a push button, in the other half shell formed an eyelet. Both are fit exactly, each arranged on the opposite side and allow in the closed state of the half-shells, that these tight with each other are closed with high accuracy of fit.

Of the PU hard foam has a high compression on its surface of the material. This particularly high stability allows it is the compound solution claimed according to the invention to realize from push button and eyelet as this is a high Requires strength and allows foaming.

Preferably At least four push buttons / eyelets in the half shells be contained, each at the edges of the Half shells are arranged.

Around Avoid air circulation and increase the sealing effect, be advantageously in the half shells of rigid polyurethane foam in a half shell a groove, formed in the counterpart spring.

additionally is it possible according to the invention Long sides of the two half-shells dowels fixed lather. On the other half-shell are recesses incorporated for screws. This can optionally be a further additional connection between the half-shells be achieved by screwing.

Preferably the half-shells made of rigid PU foam have a thickness of up to 6 cm. The maximum thickness is particularly advantageous when in winter the temperature in the area of the control unit drops to + 5 ° C, while in the control unit the temperature is up to 95 ° C is.

The usually to be isolated fittings or valve assemblies be installed differently. Therefore, advantageously on both sides of the half-shell recesses for measuring instruments pre-stamped, so that, if necessary, this to openings can be converted.

The invention will be described below with reference to an embodiment and the drawings 1 to 4 explained in more detail.

1 : shows a side view of a half shell of the PU hard foam insulation with installed fittings or valve assemblies including two holes for the screws, ball valves, measuring instruments and the pump of the valve assembly

2 : represents the front view of the two half-shells of PU rigid foam insulation in the assembled state, with built-in fittings or valve assemblies.

3 : shows the side view of the second half shell of the PU hard foam insulation with recesses for measuring instruments.

For Fittings assemblies for the safe connection of boilers to the tank with hot water boiler (as for example the Laddomat) it is necessary also isolate them so as to minimize heat loss occurs.

With the solution according to the invention can this Goal can be achieved in a simple and cost-effective manner.

For this purpose, an insulation made of rigid PU foam is used, since it is very stable and durable. The PU hard foam insulation consists of half shells ( 11 ) and has recesses for measuring instruments ( 4 ) in both half shells ( 11 ), because the valve assembly can be installed on both sides. This depends on the flow direction of the water. In addition, there are three recesses for ball valves ( 2 ) available.

On the one half shell ( 11 ) are four push buttons ( 9 ) firmly foamed and exactly opposite to the second half-shell ( 11 ) four eyelets ( 7 ). This connection system gives four very stable breakpoints, which are the two half-shells ( 11 ) together. An independent unfolding with temperature fluctuations is thus excluded. This is particularly necessary because the valve assemblies are always placed 10-20 cm above the floor and they are exposed to higher demands, such. B. in the cleaning by touching the insulation.

As a further security option is on one of the half shells ( 11 ) of the PU hard foam insulation a groove ( 8th ) and on the other half shell ( 11 ) a feather ( 10 ), precisely fitted opposite. This gives the insulation when folding the two half-shells ( 11 ) In addition, a better thermal insulation.

In the commercial sector, the demands on material and holding points are usually higher, which is why on the one half shell ( 11 ) additionally two dowels for screws ( 6 ) firmly foamed and exactly opposite to the second half-shell ( 11 ) two holes for screws ( 5 ) created. So both shells can be additionally screwed.

The PU hard foam insulation is colored black and has a thickness of 6 cm. This is an optimal thermal insulation available. Due to the PU rigid foam material, its strength and the connection system according to the invention a service life of at least 30 years.
