Abstract

The utility model discloses a prior water supply negative-pressure-free device, mainly used to solve the problem with present technique caused by insufficient water flow in time of high water consumption for production and life. The negative-pressure-free device adopted by life water supply solves life water consumption pollution. The technique scheme is mainly characterized in that the device comprises a pump, a vacuum suppressor, a control cabinet, a back valve, a storage device that has an upper exit and a lower exit and a float ball valve. Compared with present device, the utility model can first guarantee running water supply in living pipe net, so second living water pollution is prevented.

Description

Non-negative pressure water-supply installation
Technical field
The utility model relates to a kind of supply equipment, specifically, relates to a kind of production, life non-negative pressure water-supply installation.
Prior art
At present, in a lot of industrial enterprise, the inflow of tap water can not satisfy the water use peak phase and produce, the living water use requirement, but the total inflow in its 24 hours can satisfy the production in 24 hours, the requirement of living water use total amount, and the tap water inflow can satisfy peak period domestic consumption requirement, in this case, produce in order to satisfy the water use peak phase, the living water use requirement, just earlier tap water is put in the pond, and then carry out secondary with water pump and pressurize for producing, living water use, the shortcoming of this way of supplying water is: produce, living water use is lumped together, and tap water is subjected to secondary pollution after being put into the pond, has had a strong impact on the healthy of people.
Summary of the invention
The utility model provides a kind of non-negative pressure water-supply installation that can supply water by priority at existing technical problem in the prior art, and its main purpose is to solve that living water use is subjected to pollution problems when the municipal tap water inflow can not satisfy production, the requirement of living water use peak period water supply volume.
The purpose of this utility model is achieved in that it comprises switch board, water pump, butterfly valve, flap valve, bypass pipe, reservoir, float valve.Reservoir has two delivery ports, these two delivery ports are not on a horizon, the delivery port on top is by the pipeline water-accepting tank, at the pond end float valve is installed, the delivery port of bottom connects the water inlet manifold of equipment, the water inlet of water inlet manifold water pump, the delivery port of water pump connects the outfall sewer of equipment, setting pressure sensor on the outfall sewer by butterfly valve, flap valve.Water inlet on the reservoir connects city planting ductwork.
Tap water preferentially supplies living water use by the delivery port of bottom, and remaining water then enters the pond by the delivery port on top, and when tank water was full, float valve was closed, and equipment just can utilize tap water pressure.When having a power failure, tap water can supply water by bypass pipe.When tap water flow during less than domestic consumption, the vacuum compensation device is started working, and avoids producing negative pressure.Switch board comes the rotating speed and the workbench number of control of pump according to the pressure that pressure sensor provided.
Owing to adopt such scheme, can guarantee preferentially to life pipe network water supply, and unnecessary water is stored in the pond, with assurance production peak period water.
Description of drawings
Accompanying drawing is the overall structure schematic diagram of an embodiment of the utility model;
The specific embodiment
The top delivery port of reservoir 14 is by pipeline 11 water-accepting tanks 13, and a float valve 12 is installed, the bottom delivery port connects equipment water inlet manifold 17, the water inlet of water pump 3 is by the water inlet of butterfly valve 4 water pumps 3, water pump 3 delivery ports pick out supply mains 5 by flap valve 2, butterfly valve 1, bypass pipe 15 connects water inlet manifold 17 and outfall sewer 5 by butterfly valve 6, flap valve 7, and pressure sensor 8 is installed on the outfall sewer 5.Tap water water inlet pipe 11 connects the water inlet of reservoir, and vacuum compensation device 16 is installed in the top of reservoir 14.Pressure sensor 8 and water pump 3 connect switch board 9.
Its working method is: tap water is after pipeline 10 enters reservoir 14, preferentially after water pump 3 pressurizations, supply living water use through the bottom delivery port, unnecessary water enters the pond from the top delivery port through pipeline 11, after expire in pond 13, float valve 12 is closed, and equipment can make full use of tap water pressure, during 13 drawdown of pond, float valve 12 is opened, to pond 13 moisturizings; When tap water cut-off, vacuum compensation device 16 is started working, and has avoided the generation of negative pressure, and switch board 9 control of pump 3 quit work.
