| 摘要 |
The invention relates to a valve arrangement for connecting a heat exchanger (1) of a hot water extraction device to a district heating network, with a primary side valve (20), controlling a flow of heat exchange fluid through a primary side (2) of the heat exchanger (1) and a pressure-regulated secondary side valve (40), acting on a flow of process water through a secondary side (3) of the heat exchanger (1), wherein the primary side valve (20) may be operated by the secondary side valve (40). According to the invention, the production of such a valve arrangement may be achieved with a simple design by arranging the primary side valve (20) in a first housing piece (51 ) and the secondary side valve (40) in a secondary housing piece (52), both housing pieces (51, 52) being connected to each other by means of a third housing piece (53) which houses an actuating device (47) by means of which the primary side valve (20) may be operated by the secondary side valve (40). |
