What are the design rules for water separators, water collectors and accessories?

1. The inlet and outlet of each loop heating pipe shall be connected with the water distributor and the water collector respectively. The diameter of water distributor and water collector should not be less than the total return pipe diameter, the maximum cross-sectional velocity of water distributor and water collector should not be greater than 0.8m/s, and each water distributor and water collector should not have more than 8 branch circuits. The return pipe of each branch circuit shall be equipped with a stop valve.

2. Valves, filters, heat metering devices (systems with heat metering requirements) and valves should be installed on the water supply connecting pipeline in front of the water separator. On the backwater connecting pipe behind the water collector, a closing regulating valve should be installed, which can be replaced by a balance valve if necessary.

3. A bypass pipe should be set between the main inlet pipe of the water separator and the main outlet pipe of the water collector, and a valve should be set on the bypass pipe to ensure that water does not flow into the heating pipeline when flushing the heating pipeline system. 4, points, water collector should be set on the manual or automatic exhaust valve and drain valve.
