Abstract
The utility model discloses a vacuum water device of a water pump, which belongs to a pumping water device and comprises a water pump, a water outlet pipe and a water inlet pipe, wherein an outlet valve is arranged on the water outlet pipe of the water pump, a diversion valve is arranged between the outlet valve and the water pump, the diversion valve is communicated with the inlet end of a pump bowl, and the exhaust end of the pump bowl is connected with a water source through a return pipe. Compared with the prior art, the vacuum water device has the advantages of reasonable design, convenient use and maintenance, high efficiency, and the like, not only can meet the demand of diverting water for the water pump when a bottom valve is cleaned untimely, but also can not be provided with the bottom valve in a pumping system, so as to avoid the influence caused by the failure of the bottom valve.
Description
Technical field
The utility model relates to a kind of pumping water device, specifically a kind of negative pressure water diversion apparatus of water pump.
Background technique
Behind the starting mode of pump, must draw full water in the pump case and just can carry out pump water conservancy project work.In order after shutdown, to keep the water in the pump case not run off, at the water intake of water pump bottom valve is installed usually, the rate of fault of bottom valve is than higher, owing to getting rusty, fouling, entering reason such as impurity, usually takes place that the bottom valve valve block is stuck and the phenomenon that can not close.At this moment, after water pump is repaiied machine, water in the pump case can run off, start the diversion of to annotate again once more, in the process of filling diversion, if the valve block that blocks is not got back to closed position, just be difficult to water is filled it up with, cause the water pump can not pump water, the work of cleaning bottom valve be very loaded down with trivial details, often therefore influences the proper functioning of water pump.
Summary of the invention
Technical assignment of the present utility model is at above deficiency, and a kind of negative pressure water diversion apparatus of reasonable in design, a kind of water pump of using easy to maintenance, high working efficiency is provided.
The technological scheme that its technical problem that solves the utility model adopts is: this device comprises water pump, outlet pipe and intake pipe, on the outlet pipe of water pump, outlet valve is installed, between outlet valve and the water pump diversion valve is installed, diversion valve is communicated with the inlet end of pump bowl, and the exhaust end of pump bowl links to each other with the water source by return pipe.
Described water pump links to each other with bottom valve in being arranged on the water source by intake pipe.
During work, outlet valve is opened usually, and diversion valve cuts out, the water pump proper functioning.When water pump need be annotated diversion, close outlet valve, open diversion valve, the operation pump bowl is bled, water in the water source is under atmospheric pressure, enter water pump by intake pipe, when the exhaust end of pump bowl has water to discharge, show that the diversion in the pump is filled with, the starting water pump, open outlet valve, close diversion valve, the water pump proper functioning.
Open before the outlet valve, the water that water pump pumps flows back to the water source by diversion valve, pump bowl, return pipe, can reduce the starting resistance of water pump.
The negative pressure water diversion apparatus of a kind of water pump of the present utility model is compared with prior art, have reasonable in design, characteristics such as use is easy to maintenance, working efficiency height, can satisfy the needs of feed water pump filling diversion when having little time to clear up bottom valve, can bottom valve be installed in pumping system, with the influence of avoiding the bottom valve fault to cause yet.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is a kind of structural representation of negative pressure water diversion apparatus of water pump.
Among the figure: 1, outlet valve, 2, diversion valve, 3, outlet pipe, 4, pump bowl, 5, water pump, 6, intake pipe, 7, return pipe, 8, bottom valve, 9, the water source.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The negative pressure water diversion apparatus of a kind of water pump of the present utility model, its structure comprises water pump 5, outlet pipe 3 and intake pipe 6, on the outlet pipe 3 of water pump 5, outlet valve 1 is installed, between outlet valve 1 and the water pump 5 diversion valve 2 is installed, diversion valve 2 is communicated with the inlet end of pump bowl 4, and the exhaust end of pump bowl 4 links to each other with water source 9 by return pipe 7; Water pump 5 links to each other with bottom valve 8 in being arranged on water source 9 by intake pipe 6.
Its processing and fabricating of negative pressure water diversion apparatus of a kind of water pump of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
Claims (2)
