Abstract
The invention relates to the technical field of self sucking pumps, in particular to a self sucking pump with a backflow prevention suspension sphere. The self sucking pump comprises a pump body. A water storage chamber is arranged in the pump body and communicated with a water inlet pipeline. The upper end of the pump body is communicated with a water outlet pipeline. A containing chamber is arranged between the water inlet pipeline and the water storage chamber. The suspension sphere is arranged in the containing chamber. A baffle is arranged below the containing chamber and the water storage chamber and provided with a plurality of through holes communicated with the containing chamber and the water storage chamber. The size of the through holes is smaller than that of the maximum cross section of the suspension sphere. The containing chamber is communicated with the water inlet pipeline. The maximum cross section of the suspension sphere is smaller than the inner diameter of the water inlet pipeline. The self sucking pump is simple in structure and low in use cost.
Description
Technical field
The present invention relates to self-priming pump technical field, particularly relate to a kind of self-priming pump with anti-backflow suspension ball.
Background technique
Self-priming pump needs anti-siphon function usually in order to meet the function of " permanent self-priming of once pouring water ".General anti-siphon function connects an arm in the inlet ductwork of pump; arm installs an electric air control valve; air valve is be in closed condition in Start-up and operating performance process; in time shutting down, valve also can synchronously be opened; now air enters the inlet ductwork of pump by valve; reach the object of vacuum state destroying inlet ductwork, the liquid so in pump also would not be sucked back inlet ductwork by siphonage and cause in pump no liquid.But such device needs electrically-controlled valve synchronous with the start and stop of motor, when motor is high-voltage motor, electrically-controlled valve generally all can not do high pressure, if another connection control circuit bothers again very much, and the spool of electrically-controlled valve is all rubber-like, be easy to aged deterioration, and in time running into use scene and have explosive-proof grade to require, electrically-controlled valve is also difficult to adapt to those requirements.
Summary of the invention
It is simple that technical problem to be solved by this invention is to provide a kind of structure, has the self-priming pump of anti-backflow suspension ball.
The technological scheme that the present invention solves the problems of the technologies described above is as follows: a kind of self-priming pump with anti-backflow suspension ball, comprise the pump housing, water chamber is provided with in the described pump housing, described water chamber is communicated with inlet pipeline, the upper end of the described pump housing is communicated with rising pipe, putting chamber is provided with between described inlet pipeline and described water chamber, suspension ball is provided with in described putting chamber, baffle plate is provided with between described putting chamber and described water chamber, described baffle plate is provided with multiple through hole for being communicated with described putting chamber and described water chamber, the size of described through hole is less than the maximum cross section of described suspension ball, described putting chamber is communicated with described inlet pipeline, the maximum cross section of described suspension ball is greater than the internal diameter of described inlet pipeline.
The invention has the beneficial effects as follows: structure of the present invention is simple, user cost is low, between water chamber and intake pipe, putting chamber is set, in putting chamber, suspension ball is set, during water inlet, suspension ball is pressed on baffle plate by water feeding pressure, and current flow in water chamber from the through hole baffle plate, is being flowed out by rising pipe; When stopping water inlet after, in water chamber remaining water hydraulic pressure under, suspension ball props up the mouth of pipe of intake pipe, and the internal diameter due to intake pipe is less than the maximum cross-section area of suspension ball, and suspension ball can seal up inlet pipeline, and the water in water chamber is not refluxed.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described suspension ball is hollow rigid plastic balls.
The beneficial effect of above-mentioned further scheme is adopted to be: suspension ball adopts hollow rigid plastic balls, makes the lightweight of suspension ball, and what be easily subject to hydraulic pressure acts on accommodating indoor moving.
Further, described putting chamber is frustum cone structure, and the end face opening of described frustum cone structure is communicated with described inlet pipeline, and described baffle plate is located at the bottom surface opening of described frustum cone structure.
The beneficial effect of above-mentioned further scheme is adopted to be: putting chamber adopts frustum cone structure, for leading role is played in the movement of suspension ball.
Further, described baffle plate is mesh plate.
Further, described baffle plate is Turbogrid plates.
Accompanying drawing explanation
Fig. 1 is structural scheme of mechanism of the present invention;
In accompanying drawing, the list of parts representated by each label is as follows:
