Abstract
The utility model discloses a non-negative pressure water supply device which comprises a water inlet pipeline and a water supply pipeline, wherein the water inlet pipeline is connected with a tap water pipeline, and the water supply pipeline is connected with a user. A water inlet valve is mounted on the water inlet pipeline, two parallelly connected water supply booster sets and a water supply pressure sensor are mounted on the water supply pipeline, a steady flow compensator is arranged between the water inlet pipeline and the water supply pipeline, a water inlet of the steady flow compensator is connected with the water inlet pipeline, a water outlet of the steady flow compensator is connected with the water supply pipeline, and a steady pressure water supply device parallelly connected with the water supply booster sets is arranged on the water supply pipeline and comprises a steady pressure water supply and water inlet check valve and a steady pressure water supply and water outlet valve. When the non-negative pressure water supply device is used for supplying water for the user, tap water cannot be secondarily polluted, the pressure of the tap water in the steady flow compensator is consistent with that of a tap water source, the original pressure of the tap water pipeline can be sufficiently used, pressure difference is compensated, and water supply cost is reduced.
Description
Technical field
The utility model relates to a kind of non-negative pressure water-supply installation.
Background technology
Current traditional supply equipment, in structure, mainly comprise the back with water inlet line being connected with tap water pipeline and the water supply line being connected with user, in described back with water inlet line, water intaking valve is housed, two covers water supply supercharging unit parallel with one another and pressure of supply water sensor are housed on described water supply line, every cover water supply supercharging unit has booster water pump and flap valve, the both sides of booster water pump and flap valve are respectively equipped with water supply water intaking valve and water supply outlet valve, between described back with water inlet line and water supply line, be provided with pond, during use, back with water inlet line is connected with tap water pipeline, first tap water enters in pond, by supplying with user after water supply supercharging unit secondary pressurized, use again, the deficiency that above-mentioned traditional supply equipment exists is: 1, pure tap water is put into pond, various foreign material very easily enter pond, cause the secondary pollution at water source, contaminated water is supplied with resident family and is drunk after pressurization, affected the healthy of user, 2 tap water are put into behind pond, the whole vanishing of original pressure, and the pressurization of need to again starting from scratch is supplied water, and has increased water supply cost.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of sanitation and hygiene, tap water can not produce secondary pollution, and can reduce the non-negative pressure water-supply installation of water supply cost.
For solving the problems of the technologies described above, a kind of non-negative pressure water-supply installation of the utility model, comprise the back with water inlet line being connected with tap water pipeline and the water supply line being connected with user, in described back with water inlet line, water intaking valve is housed, two covers water supply supercharging unit parallel with one another and pressure of supply water sensor are housed on described water supply line, every cover water supply supercharging unit has booster water pump and flap valve, the both sides of booster water pump and flap valve are respectively equipped with water supply water intaking valve and water supply outlet valve, between described back with water inlet line and water supply line, be provided with steady flow compensator, the water inlet of steady flow compensator is connected with back with water inlet line, delivery port is connected with water supply line, on described water supply line, be also provided with the stabilized voltage device in parallel with described water supply supercharging unit, this stabilized voltage device comprises pressure-stabilizing water supply water inlet flap valve and pressure-stabilizing water supply outlet valve.
Adopt the non-negative pressure water-supply installation of said structure, owing to being provided with steady flow compensator between described back with water inlet line and water supply line, the water inlet of steady flow compensator is connected with back with water inlet line, delivery port is connected with water supply line, on described water supply line, be also provided with the stabilized voltage device in parallel with described water supply supercharging unit, this stabilized voltage device comprises pressure-stabilizing water supply water inlet flap valve and pressure-stabilizing water supply outlet valve, therefore tap water can not produce secondary pollution, the pressure of tap water is consistent with the pressure at water source from the beginning in steady flow compensator in addition, can make full use of the original pressure of water supply pipe, poor how many, mend how many, when the pressure of tap water meets water supply requirement, by the stabilized voltage device in parallel with described water supply supercharging unit, be that user supplies water, when the pressure of tap water is during lower than user's water supply requirement, by described water supply supercharging unit, be just user's pressurized water supply, reduced water supply cost.
