Abstract
The utility model provides a negative pressure cupping, which comprises a tube body, a water absorption tube, a water receiving pump inlet pipe, a water injection pipe, an overflow pipe and a valve, wherein both sides on the lower portion of the tube body are respectively provided with the water absorption tube and the water receiving pump inlet pipe, the water absorption tube is extended to the upper portion of the tube body in the tube body, the upper portion of the tube body is welded with a head plate, the overflow pipe is arranged on the head plate, the water injection pipe is arranged on the tube body, and valves are mounted on both of the overflow pipe and the water injection pipe. The negative pressure cupping of the utility model can be mounted on the water pump water inlet pipe to achieve negative-pressure water diversion when in suction work, which has the advantages of reasonable structure design, convenient employment and installation and reliable operation, and the negative pressure cupping is beneficial for saving electricity, which is suitable for the occasions where water pump installation can not achieve self-irrigation work and has to adopt suction type water diversion.
Description
1, technical field
The utility model relates to a kind of water diversion apparatus, specifically a kind of negative-pressure cup that is used for diversion on the pump water inlet that is installed in.
2, background technique
Pump working has self filling type and inhalation type dual mode, and water pump should adopt self filling type work usually, but because restrictions such as installation site or execution conditions cause water pump can not satisfy self filling type work, therefore, must diversion before starting mode of pump.At present, artificial diversion or vacuum pump diversion are adopted in the water pump diversion of prior art usually, and artificial diversion is installed bottom valve because of need, has shortcomings such as resistance is big, automaticity is low, troublesome poeration, only is applicable to provisional water supply occasion usually; And the vacuum pump diversion has the control complexity, shortcomings such as investment is big, operating cost is high, regular maintenance trouble.
3, model utility content
In view of above-mentioned the deficiencies in the prior art, the negative-pressure cup that the utility model provides a kind of water pump diversion simple in structure, that cost is low, convenient for installation and maintenance to use.
The technological scheme that its technical problem that solves the utility model adopts is: negative-pressure cup is made up of cylindrical shell, suction sleeve, water pump intake pipe, water injecting pipe, spill pipe and valve, both sides, cylindrical shell bottom are equiped with suction sleeve and water pump intake pipe respectively, suction sleeve reaches cylindrical shell top in cylindrical shell, cylindrical shell top and end socket weldering system, and on end socket, be equiped with spill pipe, water injecting pipe is located on the cylindrical shell, and all is equiped with valve on spill pipe and water injecting pipe.After the pipeline connection, open the valve of water injecting pipe and spill pipe earlier, and water filling is arrived till the spill pipe spilling water, close the valve of spill pipe and water injecting pipe again, make it to be the close state of envelope, when starting water pump, water pump is taken out the water in the cylindrical shell earlier, make its liquid level drop to certain negative pressure, negative pressure forces water on the suction sleeve thus, thereby has guaranteed the normal operation of water pump.
Profitable fruit of the present utility model is, can be installed in the negative pressure diversion when being used on the pump water inlet realize inhalation type work, have reasonable in design, easy to install and use, reliable, start fast, help characteristics such as using electricity wisely, the occasion that can not realize self filling type work and need take the inhalation type diversion is installed applicable to water pump.
4, description of drawings
Accompanying drawing 1 is a main TV structure schematic representation of the present utility model.
Among the figure, 1, suction sleeve, 2, cylindrical shell, 3, end socket, 4, spill pipe, 5, valve, 6, water injecting pipe, 7, the water pump intake pipe.
5, embodiment
Explain below doing with regard to 1 pair of negative-pressure cup of the present utility model of accompanying drawing below.
As shown in Figure 1, negative-pressure cup of the present utility model, form by cylindrical shell (2), suction sleeve (1), water pump intake pipe (7), water injecting pipe (6), spill pipe (4) and valve (5), cylindrical shell (2) both sides, bottom are equiped with suction sleeve (1) and water pump intake pipe (7) respectively, suction sleeve (1) reaches cylindrical shell (2) top in cylindrical shell (2), cylindrical shell (2) top and end socket (3) weldering system, and on end socket (3), be equiped with spill pipe (4), water injecting pipe (6) is located on the cylindrical shell (2), and all is equiped with valve (5) on spill pipe (4) and water injecting pipe (6).After the pipeline connection, open the valve (5) of water injecting pipe (6) and spill pipe (4) earlier, and water filling is arrived till spill pipe (4) spilling water, close the valve of spill pipe (4) and water injecting pipe (6) again, make it to be the close state of envelope, when starting water pump, water pump is taken out the water in the cylindrical shell (2) earlier, make its liquid level drop to certain negative pressure, negative pressure forces suction sleeve (1) to go up water thus, thereby has guaranteed the normal operation of water pump.The effect that suction sleeve (1) stretches into cylindrical shell (2) internal upper part is to cause because of the water of water pump after out of service flows out from suction sleeve (1) that negative pressure is destroyed, phenomenons such as water are not inhaled in water pump idle running in order to prevent.
Claims (1)
1, a kind of negative-pressure cup is made up of cylindrical shell, suction sleeve, water pump intake pipe, water injecting pipe, spill pipe and valve, it is characterized in that: both sides, cylindrical shell bottom are equiped with suction sleeve and water pump intake pipe respectively, suction sleeve reaches cylindrical shell top in cylindrical shell, cylindrical shell top and end socket weldering system, and on end socket, be equiped with spill pipe, water injecting pipe is located on the cylindrical shell, and all is equiped with valve on spill pipe and water injecting pipe.
