Description

Hand suction startup formula syphon tube

The utility model be about the method that starts siphon with hand suction with gasoline sucking-off and be input into a kind of emergent fueling vehicle in the automotive oil tank from oil drum, it can avoid doped fuel to cause in driver's mouth and do not accommodate plumbous chronic toxicity in the mouth because of sucking.

As everyone knows; the inevitable regular meeting of driver run into will be from oil drum sucking-off gasoline be added in the automotive oil tank again and go; or in automotive oil tank, gasoline is evacuated to another container; nearly all be to inhale the gasoline sucking-off at present with plastics (or rubber) pipe through port; the method of this mouthful of suction startup siphon is careless slightly will be with in the gasoline suction port; often will then can cause plumbous chronic toxicity in the doped fuel suction port; actual showing; even if suck a drop gasoline in the mouth immediately water gargle and wash; discomfort in the half an hour deutostoma is still difficult to disappear, and this is a kind of method of operation against rules.

Task of the present utility model is that the method for taking to start siphon with the hand suction shifts gasoline between container, thereby can avoid the injury of doped fuel to human body.

Its solution is: hand suction startup formula syphon tube (taking out syphon tube hereinafter to be referred as hand) is by flexible pipe, suction tube, piston, piston rod, seal ring and bonnet are formed, hose material is nylon 11 or soft polyethylene, suction tube, piston and bonnet are injection molded with polyoxymethylene, the piston rod material is a rigid polyvinyl chloride, sealing ring material is a polyurethane, with flexible pipe (long 1.5～2m, one end of internal diameter 10～15mm) is inserted on the suction tube top sub, the other end inserts in the oil drum, suction tube is divided into two sections because of internal diameter is different, at epimere (accounting for omnidistance about 85%) its internal diameter and piston matching gap is 0.1～0.15mm, the chamber was airtight mutually about seal ring made piston in this section, suction tube hypomere (lower dead point position) internal diameter and piston matching gap are 2～3mm, piston is linked up (seal ring is inoperative) in the chamber up and down, the bonnet of guiding words stopper rod is equipped with in the suction tube bottom, the suction tube top sub links to each other with flexible pipe, and chamber radial hole on piston enters the piston rod endoporus and leads to the external world under the piston.Its siphonic process is: make piston rise to the suction tube upper dead center with the hand push piston rod, flexible pipe is inserted in the oil drum, the position of suction tube must be lower than the oily plane in the oil drum, with hand piston rod is pulled down, when piston is descending in suction tube epimere interval, thereby last chamber volume enlarges gradually gasoline sucking-off in the oil drum, when the gasoline of sucking-off oil head is lower than in the oil drum oily plane, then the siphon startup is finished, when piston is pulled to suction tube lower dead centre (hypomere), piston chamber is up and down linked up, the gasoline that come out from the oil drum siphon this moment flows into chamber down through last chamber, radial hole flows to the container of being annotated continually from the piston-rod lower end oil outlet on piston again, when filling it up with (or needing the Halfway Stopping filling), only need to advance 2～3Cm can close hand inwards in piston rod and take out syphon tube, as again piston rod being pulled out as container, hand is taken out syphon tube and is continued oil transportation in container again, so hand is taken out syphon tube also have switching function in the oil transportation process.When not using hand to take out syphon tube, the flexible pipe oil absorbing end can be inserted on the piston-rod lower end fuel discharge port, in case pollutant is invaded inside.Hand is taken out syphon tube and also be can be used to aspirate other low viscous oil plant (as diesel oil) and use in other motor vehicle.

The utility model takes the hand suction to start the method for siphon, can protect the driver to avoid the injury of doped fuel.

The utility model is taked the suction tube of two kinds of internal diameters of hypomere, only needs piston rod is pulled out downwards, and siphon startup in the siphonic process and siphon oil transportation meeting are changed automatically, and be easy and simple to handle.

The utility model has switching function when the siphon oil transportation, brought convenience to oiling.

The utility model is simple in structure, all adopts injection-moulding plastic, and is easy to manufacture, cost is low.

Accompanying drawing has been described embodiment of the present utility model.

Accompanying drawing is the siphonal structural drawing of hand suction startup formula.

Hand suction startup formula syphon tube is by flexible pipe (1), suction tube (2), seal ring (3), piston (4), piston rod (5) and bonnet (6) are formed, its working principle is: establish piston (4) and be on suction tube (2) upper dead center position, flexible pipe (1) is inserted in the oil drum (A), make suction tube be in following place, the oily plane of oil drum (A), one hand-held another hand of suction tube (2) is pulled out piston rod (5) downwards, piston (4) descending causing in suction tube (2) epimere goes up that the chamber volume constantly enlarges and with the gasoline sucking-off in the oil drum (A), indoor down air is gone up radial hole from piston rod (5) stomidium discharge down through piston (4), when piston (4) when being pulled to lower dead centre, piston (4) is in the big chamber of suction tube (2) hypomere (chamber is linked up up and down), the gasoline that comes out from oil drum (A) siphon flows into chamber down through last chamber, go up radial hole from piston (4) again and flow into fuel tank (B) through piston rod (5) lower end oil outlet, this moment is as advancing 2～3Cm to piston rod (5) in suction tube (2), piston (4) chamber separates suction tube (2) and cut off outside fuel feeding (hand take out syphon tube close) up and down, as again piston rod (5) being pulled out, hand is taken out syphon tube and is continued again to refuel to fuel tank (B), therefore it has switching function in siphon oil transportation process, suction tube (2) has one 15 ° of grooves by hypomere to epimere, so that piston (4) enters suction tube (2) epimere easily and avoids a seal ring (3) to pull, when not using, flexible pipe (1) oil absorbing end can be inserted on piston rod (5) fuel discharge port, in case pollutant is invaded inside.

Claims (3)

1. the hand of being made up of flexible pipe (1), suction tube (2), seal ring (3), piston (4), piston rod (5) and bonnet (6) aspirates startup formula syphon tube, it is characterized in that: suction tube (2) epimere (accounting for omnidistance about 85%) internal diameter and piston (4) matching gap are 0.1～0.15mm (being used for siphon starts), suction tube (2) hypomere (lower dead centre place) internal diameter and piston matching gap are 2～3mm (being used for the siphon oil transportation), pull piston rod (5) and make piston (4) move up and down the then switching of may command siphon oil transportation in the last hypomere junctional area of suction tube (2).

2. according to the described hand suction of claim 1 startup formula syphon tube, it is characterized in that: all part is made of plastic.

3. according to the described hand suction of claim 1 startup formula syphon tube, it is characterized in that: flexible pipe (1) oil absorbing end is inserted in avoids inner contaminated under the piston rod (5) on the end connector.
