Abstract
The utility model discloses an anti-negative pressure water supplier, which comprises a water storage tank with a water inlet and a water outlet, and the pipeline of the water outlet is connected with a pump set in series. A water inlet pipe and a water outlet pipe of the water pump set are provided with pressure sensors, the pressure sensors and the water pump set are connected with a control cabinet, and the top of the water storage tank is provided with a switch valve. Since the top of the water storage of the utility model is provided with the switch valve, the negative pressure formed in the water storage tank is avoided. The utility model has the advantages of pipeline protection, energy saving, etc.
Description
Technical field
The utility model belongs to water supply installation, relates in particular to a kind of secondary water-supply with flow-compensated frequency-changing water supply device.
Background technology
In water system, for guaranteeing constant pressure water supply, often adopt the secondary pressurization, traditional way is to build the pond, when hydraulic pressure is enough high, carry out retaining, when water use peak hydraulic pressure is low, adopt water pump assembly to supply water or pressurization, alleviate the deficiency of peak period water supply flow, and can not influence other user's water supply.There is following defective in this supply equipment: reservoir is open, causes the water source secondary pollution easily; For avoiding secondary pollution to adopt the water tank of sealing then in jar, to form negative pressure easily, influence other user's water supply, violated the countries concerned's regulation.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, provides a kind of and can make full use of the supply equipment that can not form negative pressure in tap water pipe network pressure and the water tank.
The supply equipment that the utility model provides comprises the water tank that has water inlet and delivery port, relay pump unit on the pipeline of delivery port; The water inlet pipe and the outlet pipe of water pump assembly are provided with pressure sensor, and pressure sensor, water pump assembly connect switch board, and the top of water tank is provided with switch valve.
Switch valve in the such scheme comprises sleeve, sleeve has upper end cover and bottom end cover, inlet opening and air inlet are set respectively on bottom end cover and the upper end cover, float is set in the sleeve, the air inlet periphery of upper end cover is provided with elastic seal ring, and the float upper end of corresponding air inlet is provided with the elastic seal cap of closure or openness air inlet.
The utility model has been avoided forming negative pressure in the water tank owing to be provided with switch valve at the top of water tank, has advantages such as protection pipeline, energy conservation.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the utility model embodiment;
Fig. 2 is the structural representation of switch valve among Fig. 1.
The specific embodiment
The utility model embodiment as shown in Figure 1, water supply pipe 16 is connected to the water inlet of water tank 17, the top of water tank 17 is equipped with switch valve 18; The delivery port of water tank 17 connects water pump assembly 19, user side pipeline charging pump unit 19 outlet pipe place setting pressure sensors 20, water pump assembly 19 water inlet pipe places are provided with pressure sensor 23, pressure sensor 20 is given variable frequency control cabinet 21, the running of variable frequency control cabinet 21 control of pump units 19 with signal feedback; Water tank 17 water inlet pipes and water pump assembly 19 outlet pipe places are provided with flap valve 22.
The structure of switch valve 18 as shown in Figure 2, it comprises the sleeve 1 that has upper end cover 6 and bottom end cover 14, upper end cover 6 centers have air inlet 4, the center of bottom end cover 14 has inlet opening 12; There is housing 2 top of sleeve 1, and housing 2 is clamping with sleeve 1, and the sidewall of housing 2 has a plurality of apertures 3, and air filter 15 is housed in the cavity of housing 2; Float 13 is arranged in the sleeve 1; Float 13 is connected by the elastic seal cap 9 of guide rod 8 with its top; The lower port of air inlet 4 is bonded with elastic seal ring 7, and its internal diameter and air inlet 4 are basic identical; Guide rod 8 passes elastic seal cap 9 and extends up through air inlet 9, and the conduit 5 on its upper end and the housing 2 forms and is slidingly matched; The top of sleeve 1 inherent inlet opening 12 is provided with domed cushioning fender 10, and the double-screw bolt 11 of it and bottom end cover 14 upper surfaces forms clampings.
Practical work process is as follows: when tap water pressure was higher than setup pressure value, tap water entered water tank 17, and the air in the water tank 17 is discharged to the external world through switch valve 18, and water flows to user side after expiring in jar, and this moment, water pump assembly 19 was not worked; Tap water pressure is less than when setting value, and pressure sensor 20 is given variable frequency control cabinet 21 with signal feedback, 19 runnings of variable frequency control cabinet 21 control of pump units, and the water that extract in the water tank 17 carry out flow-compensated supercharging to user's pipeline.Along with the decline of water level in the water tank 17, switch valve 18 is opened, and filtered cleaned air enters water tank 17, just can not produce the water supply that negative pressure influences other user in the water tank 17 like this.Water in water tank 17 is evacuated, and pressure sensor 23 is given variable frequency control cabinet 21 with signal feedback, and variable frequency control cabinet 21 control of pump units 19 stop operating, and avoids idle running.
The concrete course of work of switch valve 18 is as follows: when the water level in the water tank was lower than switch valve 18, float 13, guide rod 8 and sealing cap 9 were in extreme lower position, and air inlet 4 is opened; During water filling, the air in the pond is discharged to ambient atmosphere by the cavity in inlet opening 12, the sleeve 1, air inlet 4, housing 2 and wherein air filter, aperture 3 in the pond; When the pool inner water position constantly raises, water will be from the inlet opening 12 enters in the sleeve 1 and promotes float 13, guide rod 8, elastic seal cap 9 and move upward, and is pressed on the elastic seal ring 7 until elastic seal cap 9 air inlet 4 is blocked fully; During drawdown, float 13, guide rod 8, elastic seal cap 9 move down until extreme lower position thereupon in the water tank, and air enters in the water tank by air filters, air inlet 4, the cavity of sleeve 1, inlet opening 12 in aperture 3, the housing 2.
The effect of conduit 5 is to guarantee that float 13, guide rod 8 and elastic seal cap 9 strictnesses are mobile vertically, avoids deflection to cause the bad or other problem of sealing; The effect of cushioning fender 10 is that water plays cushioning effect to current when entering in the sleeve 1, reduces the impact of current to parts such as floats, prolongs its application life; Because sealing cap 9 and sealing ring 7 all are elastic components, make both be combined with better sealing effectiveness, avoid water to flow out or ooze out from air inlet 4.
