Energy-conservation no negative pressure water storage tank
The utility model belongs to the water-supply technology field, mainly proposes the energy-conservation water storage tank of a kind of no negative pressure.
Existing energy-conservation water storage tank is to regulate by hydraulic valve, liquid level valve.The admission inflow of energy-conservation water storage tank also needs manual adjustment sometimes.But be installed in the water complex structure, cost height by the original energy-conservation water storage tank of practical application, regulation control part.Originally use, certain gas compartment is arranged in the water tank, but the gas in water tank is after a while just discharged water tank together with water, energy-saving cistern inside will be by the water absorb, this moment as output less than water supply volume, as continue water, just form negative pressure in the water tank, (because of hydraulic valve, liquid level valve are the ball float structures, buoyancy because of ball float, hydraulic valve, liquid level valve can't be opened at this moment, and gas can't enter), and influence other user.Therefore be unfavorable for requirements of saving energy.
The purpose of this utility model promptly is to propose a kind of energy-conservation no negative pressure water storage tank, and the control assembly that the structure of native system adopts is installed in energy-conservation no negative pressure water storage tank outside, and simple in structure, cost is low, and is easy to maintenance, and can realize automatic adjusting.Thereby overcome
The deficiency that prior art exists.
The technical scheme that the invention task that the utility model is finished is adopted is to comprise: energy-conservation no negative pressure water storage tank top is outside, self-checking device is set, energy-conservation no negative pressure water storage tank can communicate with outside air or airtight control assembly, this control assembly is unidirectional automatic regulating valve, the one end is connected with energy-conservation no negative pressure water storage tank, the other end is communicated with outside air, its mainly act on be when energy-conservation no negative pressure water storage tank internal pressure greater than zero the time, unidirectional automatic regulating valve is airtight to block energy-conservation no negative pressure water storage tank inner air and outer air passage, mutually should energy-conservation no negative pressure water storage tank internal pressure less than zero the time, energy-conservation no negative pressure water storage tank inner air and outer air passage is open-minded.Water level hydraulic pressure detector is installed in energy-conservation no negative pressure water storage tank bottom, can detect the water yield hydraulic pressure of energy-conservation no negative pressure water storage tank accurately and conveniently.
The utility model operating principle is: energy-conservation no negative pressure water storage tank internal pressure equals zero when initial water supply, and when tap water supplies water to energy-conservation no negative pressure water storage tank by inlet pipeline, along with the increase of inflow, this moment, energy-conservation no negative pressure water storage tank internal pressure was greater than zero-pressure.Unidirectional automatic regulating valve is in air-tight state, and supply water to high-rise user by pipeline, pump group this moment, and when the municipal tap water output was big, energy-conservation no negative pressure water storage tank internal pressure was big, and this moment, control of pump can be saved the part electric energy by the electronics automatic control cabinet.When municipal tap water output during less than user's water supply volume, energy-conservation no negative pressure water storage tank internal pressure drops to zero-pressure when following, be installed in the outside unidirectional automatic regulating valve in energy-conservation no negative pressure water storage tank top, will open automatically, energy-conservation no negative pressure water storage tank inner air and outer air passage is open-minded, has guaranteed that the municipal tap water pipe network negative pressure can not occur.
The utility model major control parts have only adopted a unidirectional automatic regulating valve, are installed in the water tank outside, and are simple in structure, easy to maintenance.Not only can utilize original pressure of municipal tap water pipe network, can guarantee again under any circumstance all can guarantee can not make to form negative pressure in the tap water pipe network, and influence the normal water of other users.
Embodiment with reference to Figure of description provides is illustrated its structure:
As shown in the figure: energy-conservation nothing is born reservoir pressure water tank (1); One way valve (2); Unidirectional automatic regulating valve (3); (be installed in energy-conservation no negative pressure water storage tank, can reach the outside, top of peak level).Pressure detector (4); Blowoff valve (5); Outlet valve (6); Booster pump group (7); Electronics automatic control cabinet (8); Pipeline (9); Pressure sensor (10).Energy-conservation no negative pressure water storage tank (1); Be connected in series one way valve (2) in the inlet channel; The interior water of energy-conservation no negative pressure water storage tank can not be refluxed, and below, energy-conservation no negative pressure water storage tank outside is provided with level pressure detector (4); Can accurately the water yield in the energy-conservation no negative pressure water storage tank (1) be passed to electronics automatic control cabinet (8); Guarantee pump group (7); Safe operation.Energy-conservation no negative pressure water storage tank (1); The unidirectional automatic regulating valve (3) that top foreign side is provided with; In order to make energy-conservation no negative pressure water storage tank (1); Be communicated with outside air or block.When inlet channel (9) is passed through in the municipal tap water; One way valve (2) enters in the energy-conservation no negative pressure water storage tank, unidirectional automatic regulating valve this moment (3) is in closed condition, and along with inflow, energy-conservation no negative pressure water storage tank (1) can reach and the same equal pressure of municipal tap water pipe network, at this moment, as passing through electronics automatic control cabinet (8); Control pump group (7); Supply water to layer user and can utilize the pressure of municipal tap water, the pump group only needs the pressure of supercharging deficiency partly to get final product.Saved the part electric energy, as the municipal tap water output during less than user's water supply volume, when energy-conservation no negative pressure water storage tank (1) pressure drops to zero-pressure when following, the unidirectional automatic regulating valve (3) that is installed in energy-conservation no negative pressure water storage tank (1) top is just opened automatically, makes energy-conservation no negative pressure water storage tank inner air and outer air passage open-minded.Guarantee negative pressure can not occur in the municipal network water supply.
