Abstract
The utility model discloses a reservoir pressure-superposed water supply device that can use tap water pipeline water pressure. The utility model comprises a tap water supply pipe, a water storage tank, a float ball valve, a pipe gate valve, a check valve, a water pressure sensor, an electric pump, a transducer and a user water supply pipeline. Water is supplemented to the water tank automatically by the float ball valve and the tap water pipe, the gate valve and the check valve are connected with a water discharge pipe on the bottom of the water tank, and the water discharge pipe is communicated with the electric pump by an entrance pipe of the electric pump, a parallel connection pipeline is at front end of the electric pump, upper end of the electric pump is communicated with the tap water pipeline, the gate valve and the check valve are communicated with middle of the electric pump, and the lower end of the electric pump is communicated with the entrance pipe of the electric pump. Compared with normal water tank water supply device, the utility model has obvious energy saving effect.
Description
Technical field
The utility model relates to a kind of water supply installation, more specifically is a kind of tap water reservoir water system.
Technical background
At present, a lot of building are because of the tap water pressure deficiency, and have built reservoir, and tap water is put into the pond, take out its water with water pump again to squeeze into water booster system, or adopt the FEEDBACK CONTROL pump rotary speed of force value with frequency conversion equipment, carry out constant pressure water supply.Its major defect is: water supply pipe pressure a bit can not utilize, and makes water pump do a lot of idle works undoubtedly, has increased mechanical wear, also consumes much electricity in vain.
The utility model content
The purpose of this utility model provides a kind of above-mentioned defective that overcomes, the energy-saving water supply system that the pressure of tap water is fully used.
The utility model is realized in the following manner: the reservoir laminating water service system, form by tap water supply pipe, reservoir and float valve, pipeline gate valve, flap valve, hydraulic pressure sensor, electric pump, frequency converter, user's supply channel, pass through float valve, the moisturizing of running water pipe self water feeding case, water tank bottom outlet pipe string has gate valve, flap valve, and be connected with electric pump by the electric pump inlet duct, the front end of electric pump also has a parallel pipeline, its upper end is communicated with tap water pipe line, the centre is connected with gate valve and flap valve, and the lower end is communicated with the electric pump inlet duct.
Because of above-mentioned cistern water supply pipeline and with its parallel tap water supply pipeline on be equipped with flap valve respectively, do not reflux even can not occur when hydraulic pressure is very low from the beginning yet, again during pump working, because cistern water supply abundance, whole design can not influence water supply pipe hydraulic pressure, so can meet the requirement of water resource management department yet because of the swabbing action of electric pump.Again because user's pressure of supply water is the constant voltage of setting, if hydraulic pressure is higher than the water tank discharge pressure from the beginning, but do not reach setting pressure, tap water pressure can be superimposed upon on the electric pump water inlet hydraulic pressure so, by the hydraulic pressure sensing, the frequency converter effect can be regulated the electric pump rotating speed automatically, reach the effect of replenishing hydraulic pressure by electric pump work, thereby alleviate the live load of electric pump; If hydraulic pressure has reached the setting pressure of supply water from the beginning, water pump just can not worked.
Comprehensive above the analysis adopts above-mentioned design can reach suitable energy-saving effect.According to the mode of occupation of present supply equipment, but laminating water supply, employing adopts common cistern water supply saves energy 50%-80%, benefit is huge.
Description of drawings and embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model water supply schematic diagram, and Fig. 2 is common cistern water supply schematic diagram.
Among the figure, 1. tap water supply pipe 2. float valves 3. reservoirs 4. gate valves 5. flap valve 6. electric pumps 7. hydraulic pressure sensors 8. frequency converters 9. users 10. gate valves 11. flap valve
Its operating principle is described in detail as follows: the pressure of supply water of establishing tap water is P1, and reservoir outlet pipe hydraulic pressure is P2, and the electric pump inlet water pressure is P3, and it is P4 that the user sets pressure of supply water, so:
(1). as P3 during greater than P2, flap valve (5) cuts out, and water (flow) direction is 1 → 10
→ 11 → 6 → 7 → 9; Original hydraulic pressure can make full use of, if P1 greater than or
Equal P4, then water pump (6) need not start and gets final product automatic water-supply;
(2). when P1 equaled P2, water pump should move, the water pressure that user (9) is located
Reach setting value P4,, and supply owing to the reservoir water surface directly is communicated with atmosphere
The water pipe current are closed with vacuum action, and current can be along 3 → 4 → 5 → 6 → 7 → 9
Direction flows, and has only few water yield to flow along 1 → 10 → 11 → 6 → 7 → 9 directions
Moving, do not influence network of rivers pressure P 1 from the beginning;
(3). when feed pipe pressure P 1 during less than reservoir pressure P 2, flap valve (11) closes
Close, current flow along 3 → 4 → 5 → 6 → 7 → 9 directions, use retaining fully
The Chi Shui water supply of pressurizeing.
