Abstract

The utility model relates to a hand-operated siphon pump for pumping fluids, which is particularly suitable for oiling by drivers. The hand-operated siphon pump adopts double functions of a siphon and a hand-operated pump and adopts a structure principle that self weight of a one-way valve shutter causes a good seal, the valve shutter is completely isolated from a sealing face, and fluids can not bring about head loss. The hand-operated siphon pump comprises a cylinder body, an oil inlet, a piston, an oil inlet and outlet guard, a cylinder head, a connecting ring, an upper shutter, a lower shutter and an oil nozzle. The utility model, which has the advantages of novel structure, convenient operation, high efficiency and low cost and has double functions of the siphon and the pump, is an ideal appliance for pumping fluids.

Description

Hand-operated siphon pump

The utility model is a kind of manual siphon pump that is used to extract various liquid, is specially adapted to the driver and refuels.

Be applicable to that at present the Liquid extracting instrument has various appearance, as large and small water pump, hand oil pump, motor-drive pump, direct current type pump, hydrocone type pump or the like, but all there is problem in various degree in these pumps, and particularly concerning the driver refueled, these pumps were all not too suitable, motor-drive pump cost height, can not use under no electric situation, direct current type, hydrocone type then must be delivered to eminence to oil in advance, and hydrocone type also must be drawn oil in advance.As the driver in the big oil drum when fuel tank refuels, earlier with chewing oil suction, completely chew gasoline, nauseating unbearably, both unhygienic, influence healthy again.Sometimes the driver shows with these ways troubles, just directly pushes over oil drum, pours in the vehicle oil drum with small container, and very science not also may cause leakage of oil to waste because of carelessness.Many drivers feel bitter brain for automobile fuel filler.

Task of the present utility model just provides a kind of easy to use, and purposes is wide, and a kind of manual siphon pump of power saving, safety and sanitary is specially adapted to the driver and refuels the manual siphon pump of usefulness.

Task of the present utility model is achieved like this: the dual functions that adopts syphon tube and hand pump.Cause excellent sealing with check valve sheet dead weight, valve sheet and sealing surface break away from fully, fluid can not produce the principle of loss of head, with hand pump and siphon pump structure in addition science combine and make a kind of novel manual siphon-pump, its structure adopts cylinder body, the oil inlet pipe handle of holding concurrently, piston, oil-feed valve cover, spring, cylinder cap, coupling ring, sheet alive, fuel-displaced chewing, go out oil valve cover etc., piston is installed in the cylinder body, and can go up, lower slider, piston handle and oil-feed handle tube combine as a whole, claim the oil inlet pipe handle of holding concurrently, the oil inlet pipe upper end is with having on the oil-feed valve cover cap of oil inlet hole in the cylinder body, the oil-feed mouth of pipe covers with the sheet of living in the cylinder body, and living sheet can be up and down, and cylinder body top is tight with the cylinder cap lid, oil outlet is by going out the oil valve cover cap, in let live sheet, oil outlet is arranged on the cover and pacifies its fuel-displaced chewing, go out oil valve cover and cylinder body and connect by coupling ring, it is whole that cylinder body becomes a sealing, has spring to support between cylinder cap and the piston.

The manual siphon pump working condition is such: when not using manual siphon pump, strutted by spring between piston and the cylinder cap, cylinder inner volume maximum, at this moment turnover sheet alive is in air-tight state with import and export by gravity, and (forward is placed, refer to that promptly the pump oil inlet pipe is in following Vertical direction), cylinder pressure and ambient atmos pressure are in state of equilibrium.When using, under external force (hand firmly) effect, spring is compressed, the cylinder inner volume reduces thereupon, because seal in the cylinder, thereby the pressure rising, import sheet alive is pressed more dead and more dead, outlet sheet alive is then opened by pressure, piston runs to upper dead center, and gas in the jar is then all discharged outside the cylinder, and at this moment gas in the jar no longer changes, by action of gravity, turnover sheet alive seals interior into and out of oil pipe voluntarily; When external force weakens, rely on the elastic force effect of spring, piston is with descending, the cylinder internal volume increases, and pressure descends, when pressure is reduced to ambient pressure, at this moment, outlet sheet alive is pressed tighter and tighter, and import sheet alive then is opened, and extraneous liquid is pressed in the cylinder, full of liquid in cylinder, thereafter continue to repeat this process, siphon can be set up, and the purpose of oil pumping and various liquid can reach.

The utility model plays all functions of syphon tube and pump, and is easy to use, with low cost, is a kind of comparatively desirable Liquid extracting instrument, welcome by the driver.

Below in conjunction with accompanying drawing the utility model is elaborated.

Figure is an embodiment's of the utility model a structural representation sectional view.

As seen from the figure, manual siphon pump is by oil inlet pipe hold concurrently handle 1, cylinder body 2, piston 3, oil-feed valve cover 4, spring 5, cylinder cap 6, coupling ring 7, the sheet 8 of upward living fuel-displacedly chews 9, go out oil valve cover 10, sheet 11 alive down, oil inlet hole 12 constitutes, and spring can adopt carbon steel, the sheet of living adopts brass to make, and other metal construction can adopt aluminum alloy.2 one-tenth drum shapes of cylinder body, the inside less or right-angle bending in bottom, to prevent that piston from skidding off, piston 3 is assemblied in the interior drum of cylinder body, and oil-feed valve cover 4 covers on the top that the oil inlet pipe cylinder interior is divided, and on the oil-feed valve cover 4 oil inlet hole 12 is arranged, the sheet 11 of living down is placed on the cylinder body 2 interior oil-feed mouths of pipe, cylinder cap 6 is arranged at cylinder body top, will go out oil valve cover 10 by coupling ring 7, and cylinder cap 6 combines as a whole, the last sheet 8 of living is placed on the fuel-displaced aperture, go out oil valve cover 10 and cover oil outlet,, go out to install on the oil valve cover 10 and fuel-displacedly chew 9 to form the sealing of cylinder body 2 inner chamber body, strut with spring 5 between piston 3 and the cylinder cap 6, spring has two at least, and under external force, piston 3 can slide up and down in cylinder body 2.Available screw thread or metal-to-metal adhesive connect between parts.

The utility model is very easy to use, only needs at oil inlet pipe hold concurrently handle 1 and the fuel-displaced flexible pipe that puts appropriate length on 9 respectively of chewing.And oil inlet pipe put into sucked liquid, and as be equipped with in the oil drum of gasoline, after this one holds the oil inlet pipe handle 1 of holding concurrently, and makes handle perpendicular to the ground.Another holds cylinder body 2, presses cylinder body up and down 3,4 times, again the pump housing is rotated 180 ℃, makes oil outlet tube hold concurrently handle 1 upwards, and fuel-displaced flexible pipe is put into and treated liquid holding container (as fuel tank), can finish the work of extracting liquid (as gasoline).

The utility model integrates the function of siphon pipe and pump, it is many to have function, volume is little, flow is big, and test shows, when the oil inlet pipe internal diameter is φ 17mm, oil outlet is φ 15mm, the fuel-displaced φ 14mm that chews, when the suction journey was 1 meter, flow can reach 11.4 liters/minute, the manual siphon pump novel structure, scientifically utilized the Gravitative Loads of check valve sheet, solved when valve is airtight leakage problem and when beginning convection cell resistance, when using as siphon pipe, valve sheet and sealing surface break away from fully, and do not produce liquid, such as the loss of flood peak, can aspirate the liquid in the container very clean. When manual siphon pump was made small-sized (miniature), the driver was very convenient to carry, had solved the bitter brain the when driver waits oiling with mouthful suction, as a kind of Liquid extracting instrument, can be widely used in all trades and professions.
