Description
Technical field
The utility model belongs to the underground liquid extracting field, is specifically related to a kind of underground liquid extracting device simple in structure, stable, with low cost and easy to maintenance.
Background technique
The equipment that extracts bottom line liquid now is generally submersible pump and Under Water Pumps.The said equipment is wanted the some or all of liquid that places in work, be easy to cause the equipment corrosion owing to soak for a long time, the unstable and rate of fault height of operation, thus cause the device maintenance inconvenience, the defective that cost is high and the life-span is short.
Summary of the invention
The purpose of this utility model is to overcome defective of the prior art and provides a kind of simple in structure, stable, underground liquid extracting device with low cost and easy to maintenance.
The purpose of this utility model is achieved in that and comprises the underground liquid pond, described underground liquid pond by pipeline successively with negative-pressure cup, centrifugal pump links to each other with the liquid using system; Be provided with inlet check valve between described underground liquid pond and the negative-pressure cup; Described centrifugal pump outer pipe place is provided with the fluid safety check; Be respectively arranged with liquid feeding stop valve and discharge line valve on the described negative-pressure cup; Described discharge line valve links to each other with atmosphere; Described centrifugal pump links to each other with power supply.Between described fluid safety check and the liquid using system backflow stop valve that links to each other with the underground liquid pond is installed.Be provided with the emptying stop valve between described underground liquid pond and the negative-pressure cup bottom.
The utlity model has simple in structure, reasonable in design, cost is low, stable, rate of fault is low, advantage easy to use and easy to maintenance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises underground liquid pond 1, described underground liquid pond 1 by pipeline successively with negative-pressure cup 3, centrifugal pump 8 links to each other with liquid using system 10; Be provided with inlet check valve 2 between described underground liquid pond 1 and the negative-pressure cup 3; Described centrifugal pump 8 outer pipe places are provided with fluid safety check 7; Be respectively arranged with liquid feeding stop valve 5 and discharge line valve 4 on the described negative-pressure cup 3; Described discharge line valve 4 links to each other with atmosphere; Described centrifugal pump 8 links to each other with power supply 11.Between described fluid safety check 7 and the liquid using system 10 the backflow stop valve 6 that links to each other with underground liquid pond 1 is installed.Be provided with emptying stop valve 9 between described underground liquid pond 1 and negative-pressure cup 3 bottoms.
As shown in Figure 1, the utility model is applicable to groundwater abstraction, well water, river, sewage, waste water, condensed liquid in urea preparing process and synthetic ammonia weak aqua ammonia.Working principle of the present utility model is as follows: will guarantee that at first discharge line valve 4, liquid feeding stop valve 5, backflow stop valve 6 and emptying stop valve 9 all are in closed condition before using the utility model; Open liquid feeding stop valve 5 and discharge line valve 4 then, in negative-pressure cup 3, fill with liquid by liquid feeding stop valve 5, original gas enters atmosphere by discharge line valve 4 in jar, close liquid feeding stop valve 5 and discharge line valve 4 again, because the effect of inlet check valve 2, the liquid that can not in the negative-pressure cup 3 flows to underground liquid pond 1; Open centrifugal pump 8, extract the liquid in the negative-pressure cup 3; After the liquid in the negative-pressure cup 3 is drawn out of gradually, form negative pressure in the negative-pressure cup 3, and to reduce negative pressure gradually increasing along with the liquid in the negative-pressure cup 3, when negative pressure acquired a certain degree the gravity that can overcome liquid and pipe resistance, the liquid in the underground liquid pond 1 can enter in the negative-pressure cup 3 automatically through inlet check valve 2; After entering liquid in the negative-pressure cup 3 and being extracted out, in fluid safety check 7 is delivered to liquid using system 10 by centrifugal pump 8 pressurizations; The liquid that centrifugal pump 8 constantly extracts negative-pressure cup 3 forms negative pressure in negative-pressure cup 3, the suction function that the liquid in the underground liquid pond 1 is subjected in the negative-pressure cup 3 constantly enters in the negative-pressure cup 3, has just finished the process with centrifugal pump 8 underground liquid extractings.
When the short time is stopped the utility model if desired, can directly centrifugal pump 8 be stopped and get final product, at this moment the liquid in the underground liquid pond 1 still can flow to negative-pressure cup 3 at short notice, but when the negative pressure in the negative-pressure cup 3 is not enough to overcome the gravity of liquid and pipe resistance, liquid in the underground liquid pond 1 will no longer flow to negative-pressure cup 3, inlet check valve 2 can be closed, prevent that the liquid in the negative-pressure cup 3 from flowing to underground liquid pond 1, keep stable negative pressure in the negative-pressure cup 3, fluid safety check 7 can cut out and prevent that centrifugal pump 8 outlet liquid from flowing backwards, and directly opens centrifugal pump 8 and get final product when needing the drawing liquid body simultaneously;
When stopping the utility model if desired for a long time, centrifugal pump 8 can stop, open backflow stop valve 6 liquid in the outer pipe is drawn go back to underground liquid pond 1, open discharge line valve 4, open emptying stop valve 9 liquid in the negative-pressure cup is entered in the underground liquid pond 1 forming normal pressure in the negative-pressure cup 3.
