Description

A kind of method utilizing siphonage water lift

Technical field

The present invention relates to a kind of water pumping method, particularly a kind of without the need to external connection power, utilize the method for siphonage water lift.

Background technology

At present, promote liquid and mostly adopt power-equipment mechanical pump to carry, and for the highland that the energy lacks, this mode is subject to larger limitation in the application.Such as in the mountain area of some oil starvation power-off, people cannot be raised to certain height for storage the bigcatkin willow of lower, have to choose animals with the shoulder back of the body and carry on the back and solve Drinking Water Problem, are just more difficult to carry out as irrigating.In order to energy conservation, facilitate mountain area water and make full use of water in natural flow, contain huge energy, the invention provides a kind of method utilizing atmospheric pressure and siphonage to promote liquid.

Summary of the invention

Object of the present invention is for solving deficiency of the prior art, provides a kind of without the need to external connection power, utilizes the method for siphonage water lift.

For achieving the above object, the technical solution used in the present invention is:

1), close control valve, discharging valve and outlet valve, fill water in pipe after, the water at high water level place, to the flowing of low water stage place, sets up siphon;

2), being arranged in siphonal peak arrange and be used for water tank gas to enter the admission B of syphon, arrange in the front end of syphon water (flow) direction upper air point B and lower than the place of syphon peak and be used for the EXIT POINT A of water outlet; Open control valve, control B point air inflow, when not destroying siphonage, making water in A point pipe maximum through non retern valve outflow flow, carry out aqueous vapor displacement and obtain best water lift efficiency;

3), close control valve, open outlet valve and discharging valve, release the water of airtight container, complete water lift, non retern valve is closed automatically, maintains siphonage in pipe;

4), discharge water and terminate after, close outlet valve and discharging valve, again open control valve, continue aqueous vapor displacement.

The present invention, relative to prior art, has the following advantages and effect:

1, siphon water lift is without the need to external connection power, utilizes the discrepancy in elevation and the natural flow in river, realizes water lift function.

2, the size due to airtight container is unrestricted, and the process that discharges water does not affect siphonage again, need not discharge water, do not have strict sequence requirement in the specific time, and can require to select container and control method according to application, application is convenient.

3, equipment is simple, cost is very low, basic Maintenance free, energy-conserving and environment-protective.

Accompanying drawing explanation

Fig. 1 is operation chart of the present invention.

In figure, 1-non retern valve, 2-control valve, 3-discharging valve, 4-outlet valve, 5-airtight container, A-syphon EXIT POINT, B-syphon admission.

Detailed description of the invention

Below in conjunction with specific embodiment, the present invention is described further:

In water-filled closing pipe line, as long as there is drop, regardless of pipeline pilot process, water to flow from high to lower, and that is, in the middle of pipeline, water to rise to higher position.Here it is siphon principle.And in fact, in the pipeline closed, be allow certain air to exist, as long as the total measurement (volume) of air is less than certain value, siphonage still can maintain the continuous-flow of water.Therefore, utilize siphonage to remain the flowing of water, send into air in pipeline eminence, displace the water in pipeline, can realize utilizing siphonage water lift.

As shown in Figure 1, water is at siphon Bottomhole pressure, arrange and be used for water tank gas to enter the admission B of syphon being arranged in siphonal peak, arrange in the front end of syphon water (flow) direction upper air point B and lower than the place of syphon peak and be used for the EXIT POINT A of water outlet; So syphon admission B is higher than syphon EXIT POINT A, syphon EXIT POINT A overpressure is higher than syphon admission B, in pipe, water flows into airtight container from syphon EXIT POINT A, air enters in pipe from syphon admission B, aqueous vapor displacement is realized in container, release the water in container again, reach the object of water lift.

First, close control valve 2, discharging valve 3 and outlet valve 4, fill water in pipe after, the water at high water level place, to the flowing of low water stage place, sets up siphon.

Secondly, open control valve 2, control admission B point air inflow, when not destroying siphonage, making the interior water of EXIT POINT A point pipe flow out flow through non retern valve 1 maximum, carrying out aqueous vapor displacement, and obtain best water lift efficiency.When water level reaches control valve 2 import, aqueous vapor displacement nature terminates, and the flowing of siphon in pipe continues.

Again, close control valve 2, open outlet valve 4 and discharging valve 3, release the water of airtight container 5, complete water lift, now non retern valve 1 is closed automatically, maintains siphonage in pipe.

Finally, discharge water after terminating, close outlet valve 4 and discharging valve 3, again open control valve 2, continue aqueous vapor displacement.

Obviously, the above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, other multi-form change and variations can also be made on the basis of the above description.Here cannot give exhaustive to all embodiments.Every belong to technical scheme of the present invention the apparent change of amplifying out or variation be still in the row of protection scope of the present invention.
