Set trap

In low temperature hot water floor radiant heating system; points catchment water flow distribution and collection combination of trap and sump from the device. Usually in the floor heating area, a large area needs to be subdivided into a cell block control, or a house, there are multiple function rooms requires separate control. Meanwhile, the floor heating system by hydraulic characteristics influence, warm coil limited to a certain length. This requires the same area or floor heating a house with each room divided into a plurality of heating loops, each loop and each needs to be turned off or flow regulation. Points, in low temperature hot water catchment floor radiant heating system to play such a role. On the one hand the heating of water main pipe heating needs by building traffic distribution, to ensure that all the regional branches of the loop flow rate required to meet the heating load. At the same time, but also to each branch circuit of water collection, and enter the heating return water main pipe, the realization of cycles. On the other hand, since the construction of each functional area (room) need to heat demand. In order to facilitate adjustment of the branch loop control, watershed and catchment equipped with valves, valve flow distribution and regulation assume tasks. To warm the structure of the system is Buried Heating end that most structures are buried in the concrete structure layer, only the sub-catchment is exposed on the outside. As a key component to warm control, its role is very important
