Abstract
The utility model provides an self-supply and well-supply water resource non-pressure water supply apparatus, consisting of a stable current replenishing device, a vacuum suppressor, a water supply pump, a control cabinet, a well pump, a filter, a counter flow prevention device, a non-return valve, a hydraulic level controller and a pressure sensor; wherein, a tap water pipe net is connected with the filter and the counter flow prevention device and then in parallel connection with a well pump water supply pipe. The pressure sensor and the hydraulic level controller are automatically switched over through the inlet of the stable current replenishing device. When water is normally supplied, the self-supply well is taken as the emergency water resource; when in use, the tap water is preferentially taken as the water resource. The utility model adopts the self-supply well as the emergency water resource,, the self-supply well is in the parallel connection with the tap water pipe net and is directly cascaded and pressurized. The tap water and the emergency well are automatically switched over and taken as double-way water intake with reliable water supply, energy saving operation and small area occupying; furthermore, the utility model can utilize pipe net water intake pressure and is mainly suitable for a secondary pressurization water supply occasion with rich underground water resource and relatively high tap water supply cost.
Description
1, technical field
The utility model relates to a kind of no-negative-pressure water supply equipment, specifically a kind of homemade well alternate source no-negative-pressure water supply equipment.
2, background technology
At present, no-negative-pressure water supply equipment is not because of establishing the pond, water tank, and can utilize tap water pipe network pressure, have to take up an area of and lack, reduced investment, operation saves money, management maintenance is convenient, automaticity advantages of higher and being used by increasing second pressure water supply occasion, but water-deficient area for some tap water supply anxiety, the employing that has improves the tap water water price amount of water conservation, the realization Timing water supply that has, and the no-negative-pressure water supply equipment of prior art adopts tap water as the water source, if in a single day the tap water pipe network breaks down or output when not enough, whole water system is in paralyzed state, and equipment can not normal water supply, and the user does not have water to use.
3, utility model content
For overcoming above-mentioned the deficiencies in the prior art, the utility model provides a kind of tap water and well water can automatically switch as the homemade well alternate source no-negative-pressure water supply equipment at water source.
The technical scheme that its technical problem that solves the utility model adopts is: homemade well alternate source no-negative-pressure water supply equipment, be by steady flow compensator, vacuum suppresser, supply-water pump, switch board, Pump for well, strainer, backflow preventer, non retern valve, fluid level controller and pressure sensor are formed, at tap water pipe network serial connection place, pressure sensor is equipped with in before the steady flow compensator import and supply-water pump exit respectively, the tap water pipe network is taken over filter, in parallel behind the backflow preventer with the well water pipe network, and by steady flow compensator inlet pressure sensor and fluid level controller realization automatic switchover, during normal water supply with homemade well as alternate source, the preferential tap water that adopts is as the water source during operation, when tap water cut-off or output deficiency, when the pressure of inlet pressure sensor is lower than the starting pressure of Pump for well setting, automatically start water supply by switch board control Pump for well, that guarantees to supply water is safe and reliable, in the Pump for well outlet non retern valve that anti-tap water flows backwards is housed, and is provided with the safe operation of fluid level controller with the protection Pump for well at the low liquid level place of homemade well; When tap water came water or water ebb, when the tap water pressure cell pressure was higher than inlet pressure sensor pressure, Pump for well was out of service automatically, recovered tap water pipe network normal water supply.
The beneficial effects of the utility model are, adopt homemade well as alternate source, and with the parallel connection of tap water pipe network after directly be connected in series pressurization, tap water and homemade well automatically switch and intake as two-way, water supply security is reliable, and directly is connected in series with pipe network, can utilize the pipe network intake pressure, energy saving in running takes up an area of little.
4, description of drawings
Accompanying drawing 1 is a process structure schematic diagram of the present utility model.
Among the figure, 1, steady flow compensator, 2, vacuum suppresser, 3, supply-water pump, 4, switch board, 5, Pump for well, 6, strainer, 7, backflow preventer, 8, non retern valve, 9, fluid level controller, 10, the tap water pressure sensor, 11, inlet pressure sensor, 12, outlet pressure sensor.
5, the specific embodiment
Explain below doing with regard to 1 pair of homemade well alternate source no-negative-pressure water supply equipment of the present utility model of accompanying drawing below.
As shown in Figure 1; homemade well alternate source no-negative-pressure water supply equipment of the present utility model; be by steady flow compensator (1); vacuum suppresser (2); supply-water pump (3); switch board (4); Pump for well (5); strainer (6); backflow preventer (7; non retern valve (8); fluid level controller (9) and pressure sensor (10); (11); (12) form; at tap water pipe network serial connection place; pressure sensor (10) is equipped with in before steady flow compensator (1) import and supply-water pump (3) exit respectively; (11); (12); the tap water pipe network is taken over filter (6); backflow preventer (7) back is in parallel with Pump for well (5) water supply network; and by steady flow compensator (1) inlet pressure sensor (11) and fluid level controller (9) realization automatic switchover; during normal water supply with homemade well as alternate source; the preferential tap water that adopts is as the water source during operation; when tap water cut-off or output deficiency; when the pressure of inlet pressure sensor (11) is lower than the starting pressure of Pump for well (5) setting; automatically start water supply by switch board (4) control Pump for well (5); that guarantees to supply water is safe and reliable; in Pump for well (5) outlet the non retern valve (8) that anti-tap water flows backwards is housed, and is provided with the safe operation of fluid level controller (9) with the protection Pump for well at the low liquid level place of homemade well.During normal the operation, tap water is flowed through and is entered steady flow compensator (1) behind strainer (6), the backflow preventer (7), steady flow compensator (1) outlet is connected with supply-water pump (3), supply-water pump (3) is realized constant pressure water supply by outlet pressure sensing (12) device, when the pressure of the inlet pressure sensor (11) of tap water is lower than setup pressure value, proof tap water cut-off or output are not enough, and Pump for well (5) is devoted oneself to work automatically; When the pressure that comes water or enter water low peak period, tap water pressure sensor (10) when tap water was higher than the pressure of inlet pressure sensor (11), Pump for well (5) was out of service automatically by setting program, recovers tap water pipe network normal water supply.
