Abstract
The invention relates to a liquid supply system wherein liquid, such as for example, a supply of warm water, circulates. Said system consists of thick outer tubes, the inner chamber of said thick outer tubes allowing a liquid to flow through, a thin inner tube is respectively placed inside the outer tube in which the liquid can flow in the direction counter to that in the inner chamber. In the path of at least one outer tube, a first tube branch is introduced enabling the first inner tube to be withdrawn, and in said first branch, at least one functional component, such as a shut-off valve, is introduced into the inner tube and guided to a second tube branch in the path of an outer tube and extends further through said tube branch and then into the inner chamber of the latter outer tube.
Claims11
Liquid supply with a circulation, for example a hot water supply, comprising thick outer pipes, in the inner space of which
- a liquid can flow and
- a thin inner pipe is installed in each case, in which the liquid can flow in the opposite direction to that in which it can flow in the inner space, and
- having a T-connection of outer pipes and inner pipes, characterized in that
- for producing a T-connection a pipe branch is inserted in each case into all three outer pipes that lead to the connection point, and
- the outer pipes running to the T-connection are connected to one another in a second T-piece, whereby at the place where in the course of one of the outer pipes one of the braches is inserted, through which one of the inner pipes is led outwards, here, at least one balancing valve is inserted into the inner pipe.
