Layout and laying pipe hot water supply system
1 pipe system of hot water supply arrangement
Piping hot water supply system arrangement may be using downfeed type or drop type. Figure 3 - 5 shows the same course
Full circulation down on schematic for pipeline layout, figure 3 - 6 shows the different programs of natural circulation drop tube
Schematic arrangement.
(1) F for death to horizontal trunk pipe can be arranged in a trench or in the basement, but does not allow direct buried.
Horizontal pipe especially tubular linear expansion coefficient of pipe to a compensator, and the highest water distribution point exhaust, Party
Law is the circulating pipe should be at the highest point of distribution about o.5m with a water pipe connection. In order to facilitate the exhaust and drain, heat
The water pipe shall be opposite with the water flow direction of the slope, the slope should be greater than or equal to o o03, and the lowest in the network
Provided with the drain valve, so that maintenance
(2) drop type horizontal trunk pipe arranged in the top if ceiling or roof, and with the direction of flow
Counter is equal to or greater than the o.o03 grade, the highest point not exhaust valve. Cold, hot water pipes arranged horizontally, the hot water pipe
In death, the cold water pipe in cold, hot water pipe: vertical layout, hot water pipeline in the left, cold water pipes in:
2 hot water pipe network laying
Hot water pipe network laying clear and dark outfit in two forms. Bright outfit is along the pipeline, beams, columns, walls ceiling,
Ground exposed laying 'flush is the pipeline or reserved grooves in the pipe hidden laying. The riser and hot water
The transverse joints, in order to avoid pipeline expansion damage. Connected with the B word bent, as shown in Figure 3 - 7 shows.
The hot water pipe is arranged in the floor, wall bushing wear and building foundation at the palace, wall bushing with both ends of the wall decoration surface
Qi, toilet, kitchen riser sleeve should be higher than the ground decoration room decoration 50mm, other higher ground 20Mmo
The need for flow adjustment and maintenance, should be installed in the water distribution, water valve stem end tube. In order to prevent the heater
The water flow was emptying caused by accidents and prevent cold water into hot water system of water distribution points to water temperature, should be in the
Heater cold water supply pipe and mechanical cycling second circulation return pipe is provided with a check valve, as shown in Figure 3 - 8 shows.
