Description
Technical field
The utility model relates to a kind of water supply installation, is the cabinet type tap water pumping plant for being connected with municipal tap water specifically.
Background technology
Along with the development of science and technology, increasing high building appears in the visual field of people, in order to make each floor in high building use municipal tap water, high building all can be provided with cabinet type tap water pumping plant.
At present, the cabinet type tap water pumping plant used in industry comprises cabinet, water pump, outfall sewer and water inlet manifold is had in cabinet, outfall sewer and water inlet manifold all have one end to reach outside cabinet, that one end that pump mouth and the water inlet manifold of water pump are positioned at cabinet is connected, and that one end that water delivery nozzle and the outfall sewer of water pump are positioned at cabinet is connected.During use, water inlet manifold is connected with municipal tap water pipeline, outfall sewer is connected with waterpipe, start water pump, the tap water in water supply pipe is extracted in outfall sewer.Traditional pumping plant in use, when municipal tap water cut off the water or water-supply shortages time, there will be negative pressure in water pump, contracting held the application life of water pump.
Utility model content
The technical problem that this law utility model will solve is to provide a kind of cabinet type tap water pumping plant, and in this pumping plant, the application life of water pump is longer.
For solving the problem, provide following technical scheme:
Cabinet type tap water pumping plant of the present utility model comprises cabinet, has water pump, outfall sewer and water inlet manifold in cabinet, and outfall sewer and water inlet manifold all have one end to reach outside cabinet, and that one end that pump mouth and the water inlet manifold of water pump are positioned at cabinet is connected.Be characterized in that described water inlet manifold has one way valve.The water delivery nozzle of described water pump is connected by the water inlet of pipeline with a two-position three-way valve.That one end that first delivery port and the described outfall sewer of described two-position three-way valve are positioned at cabinet is connected.Have water tank in described cabinet, water filling port is arranged at this water tank top, and backflow import is arranged at the top of its sidewall, and bypass outlet is arranged at the bottom of its sidewall, and the second delivery port of described two-position three-way valve is connected with the backflow import of water tank by pipeline.The bypass outlet of described water tank is connected with that section of water inlet manifold of pump house with described one way valve by pipeline, and this pipeline has electromagnetic valve.Described two-position three-way valve is connected with controller by wire, and controller is connected with electromagnetic valve with one way valve by wire.
Wherein, sewage draining exit is arranged at the bottom of described water tank sidewall.
Take above scheme, have the following advantages:
Owing to water inlet manifold having one way valve in cabinet type tap water pumping plant of the present utility model; The water delivery nozzle of described water pump is connected by the water inlet of pipeline with a two-position three-way valve; That one end that first delivery port and the described outfall sewer of described two-position three-way valve are positioned at cabinet is connected; Have water tank in described cabinet, water filling port is arranged at this water tank top, and backflow import is arranged at the top of its sidewall, and bypass outlet is arranged at the bottom of its sidewall, and the second delivery port of described two-position three-way valve is connected with the backflow import of water tank by pipeline; The bypass outlet of described water tank is connected with that section of water inlet manifold of pump house with described one way valve by pipeline, and this pipeline has electromagnetic valve; Described two-position three-way valve is connected with controller by wire, and controller is connected with electromagnetic valve with one way valve by wire.During use, water inlet manifold is connected with municipal tap water pipeline, outfall sewer is connected with waterpipe, start water pump, fill water by the water filling port of water tank by water tank, when municipal tap water regular supply simultaneously, when controller detects that the hydraulic pressure of tap water can make one way valve open, controller control the water inlet of two-position three-way valve communicate with the first delivery port, obstructed with the second delivery port, closed electromagnetic valve, pumping plant is past uses waterpipe normal water supply; When municipal tap water cuts off the water or water-supply shortages, when controller detects that running water pressure cannot make one way valve open, controller control the water inlet of two-position three-way valve communicate with the second delivery port, and the first delivery port obstructed, electromagnetic valve is opened, water in water tank water pump reflux import, circulate between two-position three-way valve and bypass outlet, make to there will not be negative pressure in water pump, thus the application life of water pump in pumping plant can not be shortened.
Accompanying drawing explanation
Fig. 1 is the structural representation of cabinet type tap water pumping plant of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, cabinet type tap water pumping plant of the present utility model comprises cabinet 1, be provided with water pump 2, outfall sewer 3 and water inlet manifold 4 in cabinet 1, outfall sewer 3 and water inlet manifold 4 all have one end to reach outside cabinet 1, and that one end that pump mouth and the water inlet manifold 4 of water pump 2 are positioned at cabinet 1 is connected.Described water inlet manifold 4 there is one way valve 5.The water delivery nozzle of described water pump 2 is connected by the water inlet of pipeline with a two-position three-way valve 6.That one end that first delivery port and the described outfall sewer 3 of described two-position three-way valve 6 are positioned at cabinet 1 is connected.Water tank 7 is had in described cabinet 1, water tank 7 is in vertical, and water filling port 8 is arranged at its top, and backflow import 9 is arranged at the top of its sidewall, bypass outlet 10 is arranged at the bottom of its sidewall, and the second delivery port of described two-position three-way valve 6 is connected with the backflow import 9 of water tank 7 by pipeline.The bypass outlet 10 of described water tank 7 is connected with that section of water inlet manifold 4 between water pump 2 with described one way valve 5 by pipeline, and this pipeline has electromagnetic valve 11.Described two-position three-way valve 6 is connected with controller 12 by wire, and controller 12 is connected with electromagnetic valve 11 with one way valve 5 by wire.Described in the present embodiment, sewage draining exit 13 is arranged at the bottom of water tank 7 sidewall.
