Abstract

The piston-type suction drainage apparatus is a drainage apparatus which utilizes pistons and the siphon principle, and thereby, the utility model is provided with pumping and siphon two functions. The utility model can be used for liquid drainage in every industry, when the utility model is carried by a driver, the drainage method of sucking oil with mouth is eliminated even in travelling. The utility model is mainly composed of a holder body, an elastic piston, and a piston rod with a handle. The utility model has the advantages of simple structure, handiness, and easy portability, liquid leakage during the liquid filling can be avoided, and the utility model is an ideal liquid filling apparatus.

Description

Piston-type suction drainage apparatus

The utility model relates to a kind of hand-operated tools of imbitition, is applicable to that particularly the piston type that automobile refuels from oil drum toward fuel tank in the driving way or from fuel tank oil taken out extracts drainage device.

For from the container that fills liquid to another container transport liquid, following several method commonly used:

1, adopt liquid pump, but pump is used in generally and do not need the place of carrying, and complex structure, the price height, volume is big, and also needing power supply could turn round.

2, adopt pump or manual pump directly to pour into container, if two containers then will have the container of an intermediate transfer can not be mobile the time, this kind pump or manual pump volume are big, are not easy to carry.

3, the ball formula liquid taking device that rises, because the man made rubber of oil resistant lacks flexibility, the natural rubber of good springiness is oil resistant not, and the liquid taking device that this kind made with rubber is fragile, and the life-span is short, is unsuitable for carrying oils.

4, syphon tube drainage, adopting the siphon principle drainage is present customary way, however the driver adopts mouth to attract stream.Though adopt the method simple and feasible, the antiknock agent tetraethyllead in the oil is poisonous, can make people's lead poisoning in the suction nozzle, uses the method can make people's numbness in hands and feet for a long time, and is slow in reacting.

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art exactly, and provides a kind of structure small and exquisite, and is easy to carry, uses flexibly, and the piston type of energy safety extracting liquid extracts drainage device.

The purpose of this utility model is achieved like this: adopt principle of negative pressure, make the liquid in the first container under atmospheric effect, enter the liquid inlet pipe that this piston type extracts drainage device, through repeatedly action, make liquid be raised to the height that can produce siphon, use the siphon mode imbitition then, as gasoline, diesel oil, kerosene, beauty and make-up liquid, edible oil, beverage etc.

Key structure of the present utility model; be to have adopted the piston mechanism and the one-way cock that can produce negative pressure; in the inlet of liquid inlet pipe pipe joint and fittings body are housed; valve ball and spacing spring are housed in fittings body; use nut that filter screen is fixed on and constitute suction nozzle on the fittings body, filter screen can prevent that solid particle or other impurity from entering in the body.At first liquid inlet pipe is inserted when using this piston type to extract drainage device and got below the liquid level of liquid container, if once get liquid measure when big, need to guarantee to insert enough degree of depth, in order to avoid get in the liquid process because liquid level descends, make the end of liquid inlet pipe be higher than liquid level, cause and get the interruption of liquid process.Best way is the bottom that suction nozzle is inserted into container, elder generation's driving handle forward when needs are got liquid, because the effect of elastic piston, air in the body is compressed, the air of compression is pressed to the unidirectional valve ball in the suction nozzle body sealing surface of suction nozzle body, make the passage sealing of leading to liquid inlet pipe, continue driving handle, because compressed-air actuated thrust, move after making elastic piston, the through hole of compressed air on elastic piston discharged to the liquid-discharging tube direction, when elastic piston was pulled to the body top, gas was discharged from the body.Be pulled outwardly active handle this moment rapidly, elastic piston moves behind the edge of a wing, because the resistance of air has sealed the through hole of elastic piston, therefore between elastic piston and suction nozzle, form negative pressure, so being attracted, the valve ball at suction nozzle body place leaves suction nozzle body sealing surface, pull on active handle, this moment, the air of liquid inlet pipe was drawn in the body, because the body inner air pressure is lower than barometric pressure, atmospheric pressure is pressed into certain altitude in the liquid inlet pipe getting liquid, be pulled near end cap when being body reducing position at elastic piston, rapid driving handle, make elastic piston forward, air between elastic piston and the suction nozzle is compressed at this moment, under the acting in conjunction of pressurized air and the deadweight of feed liquor liquid in pipe, pushes the unidirectional valve ball at suction nozzle body place to liquid entering hole, block the passage of liquid in pipe row, thereby make the liquid that advances liquid-in pipe remain on certain height to liquid inlet pipe.Repeat above-mentioned action, until liquid is sucked in the body.Maybe can lower in when being got liquid level if this device present position is lower than when being got liquid level this moment, and handle is outwards moved limit position to, and promptly near end cap, liquid is just flowed into other and collects container from getting the drain pipe of liquid container through this device, promptly forms siphon this moment.When getting the liquid capacity, from get liquid container, extract liquid inlet pipe, make the liquid inflow in liquid inlet pipe and the body collect container.If this device is higher than by the liquid level of extracting container and can not lower the time, but driving handle makes the small diameter part of elastic piston in body divide quick reciprocating action, this device is used as pump uses and just can extract liquid out.The body of this device is held in the hand unlikely skidding when the driving handle in order to make, and therefore is shaped on decorative pattern gripping the body surface, and this piston type extracts body, end cap, gland and the relevant equal available metal of link or the plastics of drainage device and makes.Some functional parts of the utility model can be made into various forms, can use leather cup formula piston, sealing ring type piston as elastic piston, and other adds check valve film, has exhaust port on the elastic piston; Unidirectional valve ball also can change cone spool into; The type selecting of handle also can be varied.

Adopt this piston type to extract drainage device and get oil, can exempt drivers up to a million inhale gasoline, diesel with mouth in the driving way hardship, exempt from the misfortune that lead poisoning and harmful components cause; It is skilful, easy to carry that this piston type extraction drainage device has light in structure, advantages such as low price, and this piston type extracts drainage device can finish the drainage work of a container to another container in several seconds or tens seconds, convenient and time-saving; This piston type extracts drainage device extraction water class suction height and can reach more than 1.5 meters, and the oils suction height can reach more than 2 meters; This piston type extracts drainage device and can be made into all size, different profiles, and flow is little counts liter to per minute, arrives per minute liter more than 100 greatly.This piston type extracts drainage device and uses extensively, the industry that also can be used for spraying paint is drawn solvent, as alcohol, banana oil, gasoline, and commercial department is as the drainage of selling goods, the liquid siphon of the retort of test room, reaction tank, reaction tank can be surveyed sample the article of stock's liquid with it in the storehouse.
