Abstract

The utility model discloses a siphon type liquid taker which is used for taking the liquid, and the utility model is composed of a sleeve barrel, a piston, a piston rod, liquid inlet pipe, liquid outlet pipe, etc. The diameter of the back valve of the siphon type liquid taker is larger than the diameter of the piston, and the back valve makes interference fit with the inner wall of the sleeve barrel; the end cover of one end of the liquid inlet pipe is provided with a back stop shutter; the inside of the end cover of one end of the piston rod hole is provided with a sealing cushion and a momentum sealing cushion to seal and is provided with a liquid back slot; a semicircular elastic joint head is sheathed on the piston rod and is fixed on the back valve. The utility model has the advantages of simple structure, little abrasion of the piston and the sleeve barrel, long service life, large negative pressure, good sealing, no liquid leakage, low cost, etc.

Description

The hydrocone type liquid taking device
The utility model relates to a kind of hydrocone type liquid taking device, belongs to a kind of pumping device.
In daily productive life, the displacement of liquid, the conversion of container such as driver refuel or temporarily when fuel tank is taken oil to automotive oil tank with providing oil drum for oneself, the driver usually attracts a siphon to reach the purpose that oil is got in oiling by general sebific duct with chewing, do not do a good job in this way also can suck and chew, often oil suction, diminish the healthy of driver, CN87211311 discloses a kind of " hydrocone type pumping cylinder ", it adopts piston structure, piston and barrel reciprocating friction, reduce working life, thereby also improved its cost.
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and provide a kind of piston system rigorous, good seal simple in structure, no leakage, air tight, negative pressure big, long service life, hydrocone type liquid taking device that cost is low.
The purpose of this utility model is achieved in that it comprises sleeve, piston, piston rod, liquid inlet pipe, liquid-discharging tube, sealing gasket, reverse stop valve, and piston places in the sleeve, with sleeve lining movingly.Piston rod one end is connected with piston, and the other end is connected with handle, and its reverse stop valve diameter cooperates with sleeve lining interference size greater than piston diameter; The check flashboard is located in the end cap of liquid inlet pipe one end, and the sleeve top is tightened by sleeve and the two screw thread of end cap, and it changes convenient, and its also double sealing gasket of doing is used; Be provided with two sealing gaskets in the end cap of piston rod hole one end, nexine sealing gasket diameter is the momentum sealing gasket greater than sleeve diameter, and this structure has been strengthened the sealing load in piston rod garden week; Half garden shape elasticity is met and discussed and is sleeved on the piston rod, and is fixed on the reverse stop valve, and it prevents that the piston setscrew nut from colliding damage momentum sealing gasket, plays the piston rod three seals simultaneously.Return outer heat-extraction system and discharge in order to make piston bring the dead point partially liq into, be provided with the liquid liquid return trough in the end caps of piston rod hole one end.For increasing the area of contact of piston and sleeve, on piston friction face, be provided with microgroove, to strengthen frictional force, improve toughness of material, help the formation of stagnant liquid body and keep liquid film, reduce the wearing and tearing of piston and sleeve lining, improve working life, favourable intensified negative pressure.
The utility model compared with prior art has following advantage:
1, piston system is simple and reasonable;
2, the wearing and tearing of piston and sleeve lining are little, long service life, and the reverse stop valve on the piston cooperates with sleeve lining interference size, thereby negative pressure is big, effluxes spray column and can reach several meters, easily causes siphonage;
3, plate, elasticity are met and discussed because reverse stop valve, check are heard, the momentum sealing gasket all have difunctional, good sealing effect, no leakage;
4, easily damaged parts is changed conveniently;
5, this device is made with plastics (PA) material and rubber processing, thus have anticorrosive, in light weight, cost is low.
Accompanying drawing is a structural representation of the present utility model.
Among the figure: handle (1), end cap (2), liquid return trough (3), momentum sealing gasket (4), sleeve (5), elasticity are met and discussed (6), packing ring (7), piston (8), tightening nut (9), liquid inlet pipe (10), check flashboard (11), liquid-through hole (12), reverse stop valve (13), piston rod stop nut (14), piston rod (15), liquid-discharging tube (16), sealing gasket (17).
Below in conjunction with drawings and Examples in detail the utility model is described in detail:
It is made up of sleeve (5), piston (8), liquid inlet pipe (10), liquid-discharging tube (16) etc., piston (8) places in the sleeve (5), it and sleeve (5) inwall are movingly, piston rod (15) one ends are connected with piston (8) by tightening nut (9), the other end is fixed on the handle (1), piston (8) is provided with liquid-through hole (12), and reverse stop valve (13) is fixed on the piston (8) by piston rod stop nut (14), packing ring (7), and liquid-through hole (12) constitutes non-return flap relatively.The elasticity of half garden shape meet and discuss (6) be sleeved on the piston stalk (15), and be fixed on the reverse stop valve (13).Be provided with end cap (2) at the sleeve two ends, in the end cap (2) of piston rod hole one end, be provided with two sealing gaskets (17,4), the diameter of nexine sealing gasket (4) is greater than the internal diameter of sleeve (5), it is momentum sealing gasket (4), locate also to be provided with liquid return trough (3) at end cap (2), on sleeve (5) barrel of nearly piston stalk hole one end, be provided with liquid-discharging tube (16), pass in the container by flexible pipe, liquid inlet pipe (10) is housed on the end cap of the other end (2), front end and the middle check flashboard (11) that is equipped with of end cap (2) at sleeve (5), it is tightened by the screw thread on this pipe box tube (5) and the end cap (2), and it is convenient that check is heard plate (11) installation replacing like this, the double simultaneously seal ring of doing.Check flashboard and check flashboard frame are offset plate, are cut into ligule and connect.

Claims (2)

1, a kind of hydrocone type liquid taking device comprises sleeve, piston, piston rod, liquid inlet pipe, liquid-discharging tube, sealing gasket, reverse stop valve, and piston places in the sleeve, with sleeve lining movingly, piston rod one end is connected with piston, the other end is connected with handle, it is characterized in that;
