The specific embodiment
Embodiment one is regularly a circulation pipe network, the control method of pipe network circulation and regularly the circular flow control device is as shown in Figure 2: volume control device is made up of holding valve or Counterflow-proof device 1, flow control valve 2 (claiming constant flow rate valve again), magnetic valve 3.Magnetic valve is by time switch time opening or manually opened, and the flow value of flow control valve 2 is set at the design cycle flow, and the operating pressure of holding valve 1 is inquired into setting according to least favorable with the operating pressure of water spot.The performance of flow control valve 2 is: after preestablishing a firm discharge, the pressure of valve upstream changes the flow that can not influence its downstream; The performance of holding valve 1 is: the hydraulic pressure of keeping the valve upstream is in a certain setting value, and when the pressure rising, holding valve is opened earial drainage.
Need circulation time, magnetic valve 3 is opened (or automatic or manual), and pressure of supply water raises the pressure before the holding valve 1.If the water consumption of pipe network is little, then pressure surpasses the force value of setting, and this valve is opened earial drainage, and looping back in the water pipe 9 has current to pass through, and circulation forms, and flow control valve 2 guarantees that circular flow is no more than the design cycle flow.Like this, the flow in water-supply-pipe 7, sparge pipe 8, the circulation pipe 9 all has been controlled within the design discharge; If the water in the pipe network is in the peak, then do not need circulation, the pressure before the valve 1 does not reach setting value, and this valve is not opened.So control circulation, water pump just can not damage because of the flow overload, and leading water outlet is also unaffected.And circular flow is controlled in the design load, saves energy.
Embodiment two is automatic circulation pipe networks, and the decapacitation of circular flow control device solves outside aforesaid two defectives automatically, can also control the automatic operation of circulation.Automatically the circular flow control device is as shown in Figure 4:
Automatically cycler is made up of holding valve 1, flow control valve 2 (claiming constant flow rate valve again).When water consumption in the pipe network less or do not have water, when needing circular flow, the pressure before the holding valve 1 in (upstream) pipeline rises, and surpasses the setup pressure value of this valve, so the holding valve earial drainage, looping back in the water pipe 9 has current to pass through, circulation forms.Flow control valve 2 guarantees that entering the flow that loops back water pipe 9 is no more than design load.As long as water consumption does not increase in the pipe network, holding valve just is in the earial drainage state, and circulation just forms automatically.Water consumption greatly, does not need circulation time in pipe network, and the loss of flood peak of water-supply-pipe 7 is big, and the pressure before the holding valve is low, is under the setting value, and holding valve is closed, and circulation does not start.
In direct drinking or domestic hot-water's centralizedly supply system, adopt automatic circular flow control device, shown in Fig. 6,8, the automatic circular flow control device that is made of holding valve 1 (is Counterflow-proof device 16 in hot-water heating system), flow control valve 2 is located at looping back on the water pipe 9 that each vertical division block distribution system of water supply end draws, and each distinguishes circulating water pipe or separately or merge and draw the open air and be connected to outdoor circulating water pipe.Outdoor circulating water pipe is only established one, collects each building circulating backwater, and different journey settings take back in the machine room of sub-district nearby.
For drinking water system, when in the pipe network certain the district water consumption less or do not have water, when needing circular flow, pressure before this district's holding valve 1 in (upstream) pipeline rises, the setup pressure value that surpasses this valve, so holding valve 1 earial drainage, looping back in the water pipe 9 has current to pass through, and current import and outdoorly to loop back water pipe 12, be back to the water tank 5 in the machine room, and circulation forms.Flow control valve 2 guarantees that entering the flow that loops back water pipe 9 is no more than design load.As long as water consumption does not increase in the pipe network, holding valve just is in the earial drainage state, and circulation just forms automatically.Water consumption greatly, does not need circulation time in certain district's pipe network, and then the loss of flood peak of water-supply-pipe 7 and sparge pipe 8 is big, and the pressure before the holding valve is low, is under the setting value, and holding valve is not opened, and does not just circulate in this district.Because drinking water system (Fig. 6) loops back hydraulic pressure in the water pipe 9,12 than each district all low in distribution system of water supply, so the circular flow through flow control valve 2 outflows in each district can both be back to the water tank in the machine room unobstructedly; For hot-water heating system, because hot water circulating pump 14 (Fig. 8) running can all be carried backheat swap tank 13 to each district through the circular flow that flow control valve 2 flows out at any time.Like this, the circulating backwater in each district can short circuit or backwater, although the outdoor water pipe that loops back is not to lay with journey.So, not only the layout of pipe network and installation can greatly be simplified, and circulating effect, and promptly the even distributivity of recirculated water greatly strengthens.
