Abstract
The utility model relates to a novel device capable of substituting centrifugal pump bottom valves, which comprises a middle water storage tank connected with a water inlet of a centrifugal pump body and is characterized in that a water outlet connected with the water inlet of the centrifugal pump is arranged at the bottom of the middle water storage tank and the top of the middle water storage tank is provided with a water inlet communicated with a water inlet pipe with a pipe opening arranged in water source. The novel device is simple in structure, convenient to overhaul, good in water pumping effect and capable of effectively prolonging service life of the centrifugal pump.
Description
Technical field
The utility model relates to a kind of new device of alternative centrifugal pump bottom valve, is applied to centrifugal pump.
Background technique
Present centrifugal pump bottom valve often accumulates mud in use easily, and along with the lengthening of service time, is easy to cause bottom valve not possess check function, thereby directly influences the work of centrifugal pump.Therefore, to the problems referred to above be the object of the utility model research.
Summary of the invention
The purpose of the utility model is to provide a kind of new device of alternative centrifugal pump bottom valve, has solved the problem that present centrifugal pump bottom valve lost efficacy easily effectively, helps increasing centrifugal pump working life and using effect.
The utility model is characterised in that: a kind of new device of alternative centrifugal pump bottom valve; Comprise the middle water storage tank that is connected with the centrifugal pump body water intake; It is characterized in that: the bottom of water storage tank is provided with the water outlet that is connected with the centrifugal pump water intake in the middle of said, and the top of said middle water storage tank is provided with the water intake that places the intake pipe at water source to be communicated with the mouth of pipe.
The advantage of the utility model: the utility model is simple in structure, can effectively prolong the working life of centrifugal pump, and maintenance is convenient, and it is effective to draw water.
Description of drawings
Fig. 1 is the utility model example structure schematic representation.
Embodiment
With reference to figure 1; A kind of new device of alternative centrifugal pump bottom valve; Comprise the middle water storage tank 2 that is connected with centrifugal pump body 1 water intake 1-1; The bottom of water storage tank 2 is provided with the water outlet 2-1 that is connected with centrifugal pump water intake 1-1 in the middle of said, and the top of said middle water storage tank 2 is provided with the water intake 2-2 that places the intake pipe 3 at water source to be communicated with the mouth of pipe.
Also be provided with in order to maintenance on the bottom of water storage tank 2 in the middle of above-mentioned and use drain opening 2-3.
Practical implementation process: in use; Because the water in the middle of the pump housing when drawing water, at first can be taken out in advance and originally be stored in the water storage tank, then the air pressure of middle water storage tank reduces and forms negative pressure; Thereby with the water at water source in the middle of intake pipe sucks in the water storage tank so that the later stage continue to draw water.This structure is convenient to device maintenance and replacing owing to external, can also increase the working life of centrifugal pump.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
Claims (2)
1. the new device of an alternative centrifugal pump bottom valve; Comprise the middle water storage tank that is connected with the centrifugal pump body water intake; It is characterized in that: the bottom of water storage tank is provided with the water outlet that is connected with the centrifugal pump water intake in the middle of said, and the top of said middle water storage tank is provided with the water intake that places the intake pipe at water source to be communicated with the mouth of pipe.
2. the new device of alternative centrifugal pump bottom valve according to claim 1 is characterized in that: also be provided with in order to maintenance on the bottom of water storage tank in the middle of said and use drain opening.
