Description
Technical field
The utility model relates to a kind of supply equipment, specifically a kind of supply equipment with the negative pressure compensating device.
Background technology
In the situation of high-rise building pressure of supply water deficiency, usually adopt the water pump pressurization to supply water; Adopt in the supply equipment of water pump pressurization water supply, in city planting ductwork, produce negative pressure, usually energy storage steady-flow tank and negative pressure compensating device need to be set between city planting ductwork and residential quarter water supply line, the negative pressure compensating device can be divided into two kinds of mechanical type and electronic types according to its operating principle, mechanical type negative pressure compensating device adopts the ball float principle, when the water yield in the energy storage steady-flow tank increased, air pressure or hydraulic pressure can back down ball float, outwards discharged unnecessary air; In the time of the discharge reduction in the energy storage steady-flow tank, absorb outside air by the negative pressure compensating device, keep the balance of energy storage steady-flow tank external and internal pressure; Electronic type negative pressure compensating device adopts electronic equipment to detect hydraulic pressure in the energy storage steady-flow tank, and with the air duct on the solenoid control negative pressure compensating device whether with the outside air conducting.The negative pressure compensating device of these two kinds of forms respectively has pluses and minuses, but common characteristics are exactly: when the negative pressure compensating device is opened, and the inner chamber of energy storage steady-flow tank and extraneous directly conducting.This has just created condition for the impurity such as the pollutant in the outside air, winged insect enter tap water, forms the secondary pollution of tap water.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, supply equipment with the negative pressure compensating device of reducing secondary pollution.
The utility model is that the technical scheme that the technical solution problem adopts is:
A kind of supply equipment with the negative pressure compensating device described in the utility model comprises the energy storage steady-flow tank, be installed in the negative pressure compensating device of energy storage steady-flow tank upper end, the upper end of described energy storage steady-flow tank is provided with water inlet pipe, the lower end of energy storage steady-flow tank is provided with outlet pipe, described outlet pipe is connected with booster water pump by butterfly valve, the pressurized water delivery side of pump connects user's water main, the control end of booster water pump is wired to switch board, it is characterized in that: described negative pressure compensating device comprises adpting flange, be arranged on the float cabin of adpting flange upper surface, be arranged in the ball float of float cabin inner chamber, the upper end of float cabin is fixedly connected with end cap, valve is installed on the end cap, the lower end of float cabin is with air flue, be fixedly connected with the U-shaped pipe in the lower surface of adpting flange, an end of described U-shaped pipe is communicated with air flue.
After adopting technique scheme, remain certain water yield in the U-shaped pipe, when the negative pressure compensating device is opened, the air of turnover energy storage steady-flow tank all will be through the filtration of U-shaped Guan Zhongshui, can avoid winged insect to enter, most of solid particulate matter in also can filtered air reduces the secondary pollution of tap water.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the structural representation of negative pressure compensating device.
The specific embodiment
As shown in Figure 1, a kind of supply equipment with the negative pressure compensating device described in the utility model comprises energy storage steady-flow tank 6, is installed in the negative pressure compensating device 5 of energy storage steady-flow tank 6 upper ends, the upper end of described energy storage steady-flow tank 6 is provided with water inlet pipe 1, the lower end of energy storage steady-flow tank 6 is provided with outlet pipe 2, described outlet pipe 2 is connected with booster water pump 13 by butterfly valve 11, the output of booster water pump 13 connects user's water main 18, and the control end of booster water pump 13 is wired to switch board 17.In the inner chamber of energy storage steady-flow tank 6 with the buffering voltage stabilizing plate 9 that vertically arranges, buffering voltage stabilizing plate 9 inner chambers with energy storage steady-flow tank 6 are separated into two parts, described water inlet pipe 1 and outlet pipe 2 lay respectively at the both sides of buffering voltage stabilizing plate 9, a plurality of through holes evenly distribute on the described buffering voltage stabilizing plate 9, the water that enters energy storage steady-flow tank 6 is evenly distributed to both sides gradually from a side of buffering voltage stabilizing plate 9, can slow down like this impact that produces when current enter energy storage steady-flow tank 6.Be provided with tank body pressure meter 4 in the inner chamber with the energy storage steady-flow tank 6 of outlet pipe 2, the signal output part of described tank body pressure meter 4 is connected to the tank body pressure signal collection terminal in the switch board 17.The signal of tank body pressure meter 4 can be delivered to by wired or wireless mode switch board 17, and the display on the switch board 17 can show the pressure in the tank body.
