Abstract
The utility model relates to a self suction device for centrifugal pumps, which belongs to processing devices without the addition of leading water in centrifugal pumps for agricultural irrigation and drainage. The utility model can realize the purpose that the utility model can automatically work without the addition of leading water under the function of air suction pipes of an internal combustion engine when a centrifugal pump is used. The utility model mainly comprises a casing, a ball valve, air suction pipes, and a floating wall valve. The utility model can be used conveniently and reaches the effect of labor saving, time saving, and force saving in use.
Description
Need not add the just treatment device of proper functioning of diversion but the utility model relates to a kind of centrifugal water pump of agricultural drainage and irrigation, particularly a kind of ICE-powered centrifugal water pump that is used for is done the self-priming effect.
At present, known centrifugal water pump, in use must fill up diversion in the pump, form vacuum, normally water outlet work, reach the irrigation and drainage purpose, it is heavy thing of peasant that centrifugal pump adds diversion in use, use very inconvenience, new improved centrifugal water pump scuttlebutt is also arranged now, as application number ZL94240099, its structure is that the outlet pipe of centrifugal pump adds a big sucker, at suction from the usefulness internal-combustion engine, water in the centrifugal pump drunk up reach the purpose that does not add diversion, but after outlet pipe is loaded onto sucker, can not use utilizing plastic flexible pipe to make water guide, be unfavorable for using and in use also will be with the plastics safety box of a Shanghai Communications University, volume is big, brings very big inconvenience to use.
The purpose of this utility model provides the self-sucking device that a kind of centrifugal water pump is used, it can not only be centrifugal pump under the suction of internal-combustion engine, finish the air sucking-off in the centrifugal pump, in the automatic suction pump of water, reach the purpose that does not add diversion, and can easily use plastic flexible pipe to make the usefulness of water guide, in use reach saving of labor, laborsaving, timesaving good result.
The utility model is achieved in that
This model utility: mainly comprise main body cover, elastomeric ball valve, two flange plate and shell be with being provided with a sucking pipe in accessory body one and that communicate up and down, be provided with a float valve in the sucking pipe, characteristics are the elastomeric ball valves that are provided with a positive garden in the shell, can in ambient air isolate naturally and also have below the ball valve float valve, float valve in sucking pipe, sucking pipe is connected in the sucking pipe of internal-combustion engine.
The utility model adopts on one after the structure, because the main body cover lower flange connects in centrifugal pump upper flange dish, under the effect of the elastomeric ball valve in main body cover, isolated in ambient air, behind the internal combustion engine, the sucking pipe of internal-combustion engine is connected in the sucking pipe of self-sucking device, under the suction of internal-combustion engine, air in the sucking-off centrifugal pump makes in the water suction pump, finishes the purpose that does not add diversion.
Below in conjunction with accompanying drawing the utility model embodiment is described in detail.
Among the figure: 1, main body cover 2, accessory body (is one in main body) 3, elastomeric ball valve 4, float valve 5, sucking pipe 6, upper flange plate 7, elastomeric ball valve card 8, lower flange 9, float valve card
The utility model mainly comprises: the float valve 4 that is provided with in main body cover 1, elastomeric ball valve 3, valve card 7, sucking pipe 5, the sucking pipe 5, float valve card 9, main body cover 1 in upper flange plate 6, accessory body 2, lower flange 8 be one casting integrated, shaped design is to be provided with ball valve 3, this ball valve 3, upper end that a rubber makes in middle garden arc, the shell 1 to be provided with the valve card 7 that is connected with shell 1, to be provided with in accessory body 2 and to be provided with float valve 4, secondary ball float card 9 in sucking pipe 5, the sucking pipe 5.
During use, flange plate 8 is linked to each other in centrifugal pump main body top, flange plate 6 is connected in water outlet, and sucking pipe 5 is connected in the suction tude of internal-combustion engine.
Working principle: after connecting on one, ball valve 3 in the shell 1 is closed automatically, and isolated in the air in the water outlet and the external world, the air in the pump is communicated by the suction tude of sucking pipe 5 in internal-combustion engine, under the suction of internal-combustion engine, sucking-off elastomeric ball valve 3 reaches the air in the centrifugal pump once.Water enters in the centrifugal pump naturally, reaches the purpose that need not add diversion, and when water entered centrifugal pump, water sprayed automatically, under the effect of water, elastomeric ball valve 3 rises automatically, and ball float 4 is under buoyancy of water, automatically close, go, solved the purpose that need not add diversion automatically into automatic work.
