Abstract
The utility model relates to a low-flow-resistance self-absorption rubber manual pump comprising a manual pump body shaped like a waist drum, wherein the manual pump body is internally penetrated with a liquid tube, and two ends of the liquid tube respectively extend outwards; the extending end at one side of the liquid tube is a liquid inlet, and the extending end at the other side thereof is a liquid outlet; the middle part of the liquid tube, positioned in the manual pump body, is provided with an overflowing cavity; the internal shaft of the overflowing cavity is upwards provided with a main one-way umbrella valve by a valve seat; and the liquid tube at two sides of the overflowing cavity are radially and respectively provided with a liquid inlet one-way umbrella valve and a liquid outlet one-way umbrella valve. The rubber manual pump is used for pumping liquid by two one-way valves, and leading the liquid to flow through by utilizing only one one-way valve; the resistance of liquid when flowing through is half of that of the existing manual pump, and the pumping pressure stroke of the rubber pump body is limited to a certain extent, so that advanced failure of the rubber pump body due to overlarge deformation is prevented, and the service life of the rubber manual pump can be prolonged.
Description
Technical field
The utility model belongs to low flow resistance self-priming rubber and plastic hand pump and the product of anti-back flow function is arranged.
Background technique
The rubber and plastic hand pump is widely used in the fuel oil supply system in the automobile industry, the manual self-priming of fluid fields such as pump industry self-suction system.Existing rubber and plastic hand pump is made up of two one-way valves of liquid in-out mouth, during pump liquid and liquid by the time all through two one-way valves, working resistance is closing of two one-way valves, resistance is big.And hand pump body stroke infinite place very easily causes elasticity hand pump body to lose efficacy.
Summary of the invention
In order to solve the big problem of working resistance that existing rubber and plastic hand pump exists, the utility model provides a kind of new structure to hang down flow resistance self-priming rubber and plastic hand pump.
The technical solution that realizes above-mentioned purpose is as follows:
Low flow resistance self-priming rubber and plastic hand pump comprises dolioform hand pump body, is running through the liquid pipe in the hand pump body, and the two ends of liquid pipe are overhanging respectively; One side overhanging end of liquid pipe is a liquid entering hole, and the opposite side overhanging end is a liquid outlet; The liquid pipe middle part that is positioned at the hand pump body is provided with the overcurrent chamber, and axially go up by valve seat in the overcurrent chamber and be provided with main unidirectional umbrella valve: the liquid caliber of both sides, overcurrent chamber upwards is respectively equipped with unidirectional umbrella valve of feed liquor and the unidirectional umbrella valve of fluid.
The unidirectional umbrella valve of described feed liquor is positioned at a radially side of liquid pipe, and the unidirectional umbrella valve of fluid is positioned at the radially opposite side of liquid pipe, and phase difference is 180 degree.
Pass through two one-way valves during the utility model rubber and plastic hand pump pump liquid, when passing through, only passes through liquid an one-way valve, liquid by the time resistance be 1/2nd of existing hand pump, and give certain limitation to the pump pressure stroke of the rubber and plastic pump housing, prevent that the rubber and plastic pump housing excessive deformation from causing inefficacy in advance, the working life of having improved the rubber and plastic hand pump.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, low flow resistance self-priming rubber and plastic hand pump comprises dolioform hand pump body 5, is running through the liquid pipe in the hand pump body 5, and the two ends of liquid pipe are overhanging respectively; One side overhanging end of liquid pipe is a liquid entering hole 11, the opposite side overhanging end is a liquid outlet 1, be tightly connected by locking strap A3 and seal ring A2 between the hand pump body 5 of liquid outlet 1 end and the liquid pipe, be tightly connected by locking strap B9 and seal ring B10 between the hand pump body 5 of liquid entering hole 11 ends and the liquid pipe.The liquid pipe middle part that is positioned at hand pump body 5 is the overcurrent chamber, axially goes up by valve seat 6 in the overcurrent chamber main unidirectional umbrella valve 7 is installed; The liquid caliber of both sides, overcurrent chamber upwards is separately installed with unidirectional umbrella valve 8 of feed liquor and the unidirectional umbrella valve 4 of fluid, and the two limit phase differences at main unidirectional umbrella valve 7 of unidirectional umbrella valve 8 of feed liquor and the unidirectional umbrella valve 4 of fluid are 180 degree.
Working principle of the present utility model is as follows: when holding when pressing hand pump body 5, the space is gradually little and be subjected to liquid outlet 1 and liquid entering hole 11 spacing in the pump housing, and the unidirectional umbrella valve 4 of fluid is opened simultaneously, and main unidirectional umbrella valve 7 and the unidirectional umbrella valve 8 of feed liquor are closed.Gas or liquid in the pump chamber are pumped by Way out.Because 5 resiliences of hand pump body produce negative pressure in the hand pump body, the unidirectional umbrella valve 8 of feed liquor is opened suction liquid and entered the hand pump body, main simultaneously unidirectional umbrella valve 7 and the unidirectional umbrella valve 4 of fluid are closed the blocking solution body and are flow backwards when openhanded opening.Repeat above-mentioned action can be continual with liquid from the importer to pumping into, pump from Way out, make full of liquid in the hand pump body.When liquid need be passed through by other power after pump liquid finishes, only the main unidirectional umbrella valve of process 7 backs were to Way out to entering from the importer for liquid, and fluid resistance is the resistance of an one-way valve.Reaching the low flow resistance of liquid passes through.But anti-back flow is self-closing in the time need not circulating.
Claims (2)
1. low flow resistance self-priming rubber and plastic hand pump comprises dolioform hand pump body, is running through the liquid pipe in the hand pump body, and the two ends of liquid pipe are overhanging respectively; One side overhanging end of liquid pipe is a liquid entering hole, the opposite side overhanging end is a liquid outlet, the liquid pipe middle part that is positioned at the hand pump body is provided with the overcurrent chamber, and axially go up by valve seat in the overcurrent chamber and be provided with main unidirectional umbrella valve: the liquid caliber of both sides, overcurrent chamber upwards is respectively equipped with unidirectional umbrella valve of feed liquor and the unidirectional umbrella valve of fluid.
2. low flow resistance self-priming rubber and plastic hand pump according to claim 1, it is characterized in that: the unidirectional umbrella valve of described feed liquor is positioned at a radially side of liquid pipe, and the unidirectional umbrella valve of fluid is positioned at the radially opposite side of liquid pipe, and phase difference is 180 degree.
