Abstract

The utility model discloses a utilization device for a remaining pressure of a pipe network; wherein, an injection pipe and a mixing decollator are positioned in a cistern of the device; the injection pipe and the mixing decollator are arranged on a same axis; the injection pipe is connected with the water inlet pipe, and the decollator is connected with the water pump. The utility model has the advantages of having simple structure, fully utilizing the remaining pressure of the pipe network, not only saving much pumping station running electric energy, but also having the obvious social benefits of stabilizing the pressure of the service pipe network and balancing the volume of the feedwater, and being applicable to water supplying and draining for the cities, industry, agriculture, industry recycling water, refrigeration of air conditioner, cooling recycling water and newly constructed and improved project of the secondary pressure pumping station for various liquids.

Description

Pipe network overbottom pressure use device

The utility model relates to a kind of pipe network overbottom pressure use device that is used for fluid.

At present, the urban skyscraper is emerge in multitude like the mushrooms after rain, and outskirts of a town are built multilayer or the new residence building group sub-district of little high level again in large area.Supporting with it water, electricity, coal gas and heating installation are people's conditio sune qua nons, i.e. " four-way " of sub-district life.Supplying water then is the problem that must at first solve in " four-way ".Owing to the highrise building story height, the original pressure in the network of rivers can't satisfy water supply requirement at all after the network of rivers connects from the beginning.The method of current solution has two kinds: a kind of is to build water tower or high level cistern; Another kind then is to use pneumatic installation water supply.These two kinds of methods carry out the capital construction also needing directly absorb water from storage cistern with water pump except that expending a huge sum of money, and the tap water pipe network must be constantly to the storage cistern moisturizing, and original pressure venting in vain in the pipe network has been wasted the pressure energy of pipe network.And the pressurized equipment such as the frequency conversion speed adjusting pump that often adopt all have an optimal flow rate adjustable range, so supply water for low discharge during the ebb water, although water pump has reduced rotating speed, but keep certain pressure, rotating speed can not reduce a lot, and the efficient of water pump sharply descends, and will waste lot of energy equally.

The purpose of this utility model is to design a kind of pipe network overbottom pressure use device of being made up of storage cistern, jet pipe and mixing diffuser tube for overcoming above-mentioned weak point.The a large amount of differential water pressures energy that are wasted in the storage cistern are all used fully.Promptly when water use peak playpipe with the press water of inlet channel with at a high speed by mixing diffuser, and the water in the part storage cistern is sent into the pump sump end and is pressurizeed; The press water that playpipe will inlet channel when the water ebb is to send into the pump sump end and pressurize by mixing diffuser at a high speed, the remainder water yield will flow in the pond simultaneously, play moisturizing effects, thereby effectively transmitted the dump energy of pipe network, well regulated the variation of water supply volume.

The utility model content:

A kind of pipe network overbottom pressure use device, comprise storage cistern, pipeline, it is characterized in that: be provided with playpipe in the storage cistern and mix diffuser, playpipe and mixing diffuser are located on same the axis, playpipe is connected with water inlet pipe, mixes diffuser and links to each other with the pump sump mouth; Playpipe is made up of water outlet spout and a cone pipe, mixes diffuser and is provided with by an end that the diffusion mouth of pipe, the other end are provided with the guiding mouth of pipe, the centre is that mixing tube is formed, and the playpipe mouth of pipe is with to guide the mouth of pipe corresponding.

Compared with prior art, the utlity model has following beneficial effect:

1. owing to adopt jet pipe to go out stream and mix diffuser structure, nozzle goes out stream, and balanced flow has been stablized pressure, and it is sufficient to supply water;

2. original pressure improves the water pump intake pressure of frequency control in the pipe network owing to having utilized, thereby pump head can be reduced, and has reduced the power that water pump consumes, and has reduced power consumption;

3. the utility model is provided with water level controller, avoids the water in the storage cistern to be evacuated, and the backflow pollution device that prevents that is loaded in the utility model inlet pipeline can prevent the water quality of backflow pollution pipe network effectively;

4. because the utility model adopts part by the storage cistern suction, and part utilizes the original water of pipe network can spray water supply, kept the part chlorine of the purification in the tap water network of rivers or the usefulness of sterilizing.

Description of drawings:

Fig. 1 is a pipe network overbottom pressure use device schematic diagram;

Fig. 2 is for mixing the detail drawing of diffuser;

Fig. 3 is the detail drawing of playpipe.

Further specify the utility model below in conjunction with drawings and Examples.

Pipe network overbottom pressure use device (Fig. 1) is made up of switch board 7, level sensor 8 and the pressure sensor 9 of backflow proof polluting device 1, fluid level control valve 2, storage cistern 3, playpipe 4, mixing diffuser 5, water pump 6, frequency control.Playpipe 4 is housed in the water storage tank and mixes diffuser 5, require both to be loaded on the same axis, the playpipe mouth of pipe is corresponding with the guiding mouth of pipe that mixes diffuser, to produce good jet action, improve the efficient of device, playpipe passes the water storage tank tank wall through pipeline and draws and link to each other with water inlet pipe from water storage tank, is provided with backflow proof polluting device 1 and fluid level control valve 2 between water inlet pipe and playpipe.Wherein: the backflow proof polluting device is made up of gate valve, automatic air valve and flap valve, and tap water flows into playpipe through the backflow proof polluting device, can also prevent the backflow pollution ductwork water quality simultaneously.Fluid level control valve can adopt float valve or motor operated valve or electromagnetic valve, also can adopt manual gate valve, and present embodiment is selected gate valve for use.Mixing diffuser passes storage cistern by pipeline and draws and be connected with water pump from storage cistern.Establish gate valve at water pump between the diffuser with mixing, so that maintenance and inspection.The delivery port of water pump leads to each feed water valve of user, between the outlet pipe of water pump and feed water valve, be provided with pressure sensor 9, the data that sensor records pass the switch board of into frequency control, this switch board sends instruction control of pump rotating speed of motor, obtain suitable hydraulic pressure, to guarantee the high-rise resident's of building water, level sensor 8 is housed on the water storage tank, when the storage cistern moisturizing, when the water level in the storage cistern drops sharply to the lowest water level line, the switch board level sensor is given the switch board signal, and switch board sends instruction and stops pump operation.The utility model has utilized playpipe to spray and the water storage tank moisturizing is supplied water, and balanced flow has been stablized pressure, and the abundance that supplies water has made full use of the original pressure of pipe network, has saved the energy.
