Abstract
The utility model discloses a micro-fluctuation start-free steady-pressure water-supply device, and the device comprises a water-supply pump. The outlet of the water-supply pump is connected with the inlet of a first valve through a check valve. The outlet of the first valve is divided into two ways, wherein one way is connected with a surge tank through a second valve, and the other way is connected with each valve of water-consuming points. The control end of the water-supply is connected with a control cabinet. The control cabinet is connected with a pipe between the water-consuming points through a pressure watch, an electrolytic point pressure meter, and the first valve. The check valve is added behind the water-supply pump, so as to avoid back flow when the water-supply pump stops. The surge tank can supply stored water during pressure reduction. The pressure watch prevents the water-supply pump from closed-pressure operation. The electrolytic point pressure meter sends a pressure signal to the control cabinet. The control cabinet sequentially controls the water-supply pump. The water-supply pump is turned off at upper limit, and is turned on at lower limit. The device provided by the utility model can prevent the water-supply pump from being started frequently, prolongs the service life, saves energy, and is in high in efficiency.
Description
Technical field
The utility model relates to a kind of stabilized voltage device, is specifically related to a kind of micro fluctuation and exempts to start stabilized voltage device.
Background technology
At present, even if general stabilized voltage device all adopts the method for pump motor being carried out to variable frequency control. reach the stable effect of output water pressure. when pipe network does not need to supply water, water pump can be in resting state. but in the situation that pipe network water supply volume is very little, water pump can restart; Situation at the frequent water of low discharge. system can frequent start-stop.
Summary of the invention
In order to solve in pressure-stabilizing water supply process, with the frequent water of water spot low discharge. the problem of the frequent start-stop of system meeting, the purpose of this utility model is to provide a kind of micro fluctuation to exempt to start stabilized voltage device, and has increased system runaway protector.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of micro fluctuation exempts to start stabilized voltage device, comprise supply-water pump 1, the entrance of supply-water pump 1 is connected with feed pipe by ball valve 4, the outlet of supply-water pump 1 is connected with the import of the first valve 6 by non retern valve 5, the outlet of the first valve 6 is divided into two-way, second valve 12 of leading up to is connected with vacuum tank 2, another road connects each valve with water spot, with each valve of water spot, be parallel form each other, the control end of supply-water pump 1 is connected with switch board 3, switch board 3 is by pressure switch 7, electrolysis point pressure table 8 and the first valve 6 with the pipeline between water spot, be connected, pressure switch 7, between electrolysis point pressure table 8, it is parallel form.
The beneficial effects of the utility model are: utilize vacuum tank retaining, and the pressure difference of upper pressure limit and lower limit, guaranteed pipe network water pressure, avoided again the frequent starting of supply-water pump, extension fixture life-span and have energy-saving effect.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
With reference to accompanying drawing, a kind of micro fluctuation exempts to start stabilized voltage device, comprise supply-water pump 1, the entrance of supply-water pump 1 is connected with feed pipe by ball valve 4, the outlet of supply-water pump 1 is connected with the import of the first valve 6 by non retern valve 5, the outlet of the first valve 6 is divided into two-way, second valve 12 of leading up to is connected with vacuum tank 2, another road connects the 3rd valve 9 with water spot, the 4th valve 10 and the 5th valve 11, the 3rd valve 9 with water spot, the 4th valve 10 and the 5th valve 11 are parallel form each other, the control end of supply-water pump 1 is connected with switch board 3, switch board 3 is by pressure switch 7, electrolysis point pressure table 8 and the first valve 6 with the pipeline between water spot, be connected, pressure switch 7, between electrolysis point pressure table 8, it is parallel form.
Operating principle of the present utility model is:
Aqueous reflux when adding a non retern valve 5 preventing that supply-water pump 1 from stopping after supply-water pump 1, vacuum tank 2 can provide retaining under pressure drop, pressure switch 7 prevents that supply-water pump 1 from closing pressure running. electrolysis point pressure table 8 is sent pressure signal into switch board 3, switch board 3 is controlled supply-water pump 1 according to this, on close supply-water pump 1 in limited time, under open supply-water pump 1 in limited time.
