Abstract
The utility model discloses an elastic reset check valve, which is characterized in that an elastic base plate which is provided with an inclined supporting plate is fixed with a half ball valve to be combined into a check valve; the elastic force of the inclined supporting rib and the elastic base plate are used to replace a spring. The utility model has the advantages of good sealing, timely resetting and corrosion resistance, and the utility model can be widely used for diaphragm pumps.
Description
The utility model belongs to the improvement of the one-way valve in the diaphragm pump.
Metal spring is adopted in the general valve resilience of one-way cock in the diaphragm pump of this transfusion usefulness, if but when carrying the very strong liquid of corrosivity, spring very piece is corroded, and makes defective valve.
The purpose of this utility model provides a kind of energy by the elastic force return of material own, low cost of manufacture, the corrosion resistant one-way valve that the life-span is long.
The technology crux that the utility model adopted be on an elastic base plate once the several twist-style yielding support of die forming muscle restore thereby drive Half ball valve fixing on the substrate to strengthen the recovery of substrate.
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 structures schematic representation
Fig. 3 is that elastic reset one-way valve A is to view
Below exemplify an embodiment by accompanying drawing, ［ 1 ］ is elastic base plate among the figure, inclined bearing muscle ［ 2 ］ is arranged on the substrate, compress in one week of substrate during by dress by the pump housing ［ 3 ］, in order to strengthen the spring-back force of diagonal bar, one side of inclined bearing muscle leans against on the pump housing, hole, one garden ［ 4 ］ is arranged in the centre of elastic base plate, fix half ball valve ［ 5 ］ in the hole, garden, Half ball valve is pressed on the valve backing plate ［ 6 ］ at ordinary times, the liquid of conveying under certain pressure when the semispherical valve direction flows into, ball valve is opened, when pressure is lower than the spring-back force of elastic base plate and diagonal bar, ball valve is closed, and also has liquid outlet ［ 7 ］ on the elastic base plate, and elastic base plate and diagonal bar can be used the elastic material once die stamping forming, Half ball valve can be used rubber according to its working pressure and the chemical property of carrying liquid, plastics, materials such as pottery are made.
The utility model has the advantages that simple in structurely, cost easy to manufacture is low, and the life-span is long, and is corrosion-resistant, can be widely used in the membrane pump, especially carries to have in the pump of corrosion property liquid.
