Abstract
The utility model relates to an elastic reset single direction valve. The single direction valve is characterized in that a base plate which is provided with ripple ribs is fixed with a half ball valve to be combined into the single direction valve, which enhances the resetting elastic force of the single direction valve. The utility model has the advantages of good sealing, timely resetting, wearing resistance and corrosion resistance, and the utility model can be widely used for diaphragm pumps.
Description
The utility model belongs to the improvement of the central one-way valve of liquid capacity-changing mechanical.
Various valves are arranged in liquid capacity-changing mechanical, as single diaphragm pump, one-way cock in the two diaphragm pump is crux parts, because pump is opened when work for a long time, closes one-way valve, make its general one-way valve produce distortion, open not as good as and influence the efficient of pump, as force return with metal spring, when the conveying corrosive liquids, not corrosion-resistant, and valve damages very fast.
It is timely that the purpose of this utility model provides a kind of switching return, the elastic reset one-way valve of long corrosion-resistant good seal of life-span.
Technological points of the present utility model is to adopt to have at one to fix half goal on the ripple rib liquid substrate and be combined into a kind of one-way valve.
Fig. 1 is that the elastic reset one-way valve is by the dress schematic representation.
Fig. 2 is an elastic reset one-way valve schematic representation.
Fig. 3 is that elastic reset one-way valve A is to schematic representation.
Below by accompanying drawing the utility model is described further, [ 1 ] is substrate among the figure, ripple rib [ 2 ] is arranged on the substrate, the rib two ends are through hole [ 3 ], substrate is all around by the pump housing [ 4 ] and water intake, the water outlet flange disc is fixed, monobasic hole [ 5 ] is arranged in the middle of the substrate, hole internal fixation one Half ball valve [ 6 ], Half ball valve at ordinary times with the pump housing on half goal pad [ 7 ] of valve fit, when liquid will promote substrate and ripple rib shape when the big garden of Half ball valve arc direction enters, Half ball valve leaves the valve backing plate, and liquid flows out in the hole at ripple muscle two ends, when pressure during less than the elastic force of substrate and ripple rib, Half ball valve and the valve pad is counter fits plays the effect of one-way cock.Substrate and corrugated elastic bar can be used the elastic material once die stamping forming, and Half ball valve can be used as materials such as glue, plastics, potteries and make according to its working pressure and the chemical property of carrying liquid.
The utility model has the advantages that simple in structurely, cost easy to manufacture is low, the life-span long and can two or more valves connection and one use.
