Abstract

The utility model discloses a seal cover with pressure drainage siphonage device, which is adapted for liquid container of various standard. The seal cover is formed by adding two guide tubes; one guide tube is used for applying air pressure and the other guide tube is used for guiding flow transfusion. When the siphon state is formed, the seal cover with pressure drainage siphonage device can make use of atmospheric pressure drainage to conduct the transfusion.

Description

Seal cover with pressure drainage siphonage device

Technical field under the utility model

The utility model belongs to the cock of liquid container.

The prior art background

The seal cover cap of all size liquid container only has the mono-sealing function at present.For example common big and small oil drum, its bung only seals.Outside from container extracting liq, the general mode of pouring into that adopts.For the drum of moving inconvenience, or when being difficult for pouring under certain situation, often adopt extractor, by ceaselessly extracting of operating personal.Because extractor inconvenience is carried.Some professional, for example the automobilist often carries sebific duct, from gasoline tank during to tank filling, the mode with chewing suction makes sebific duct be full of oil earlier, make again sebific duct one end insert fuel tank with siphon principle with oil from the gasoline tank drainage to fuel tank.This method is very unhygienic.China's utility application is for No. 85200509 to utilize the container invention of siphon technology drainage, does not have an effect of airtight lid for container but this design has only siphon automatic control drainage, and is only limited to vacuum bottle.

Utility model design-calculated purpose

Invent a kind of device on the liquid container sealing plug, simple in structure that is installed in.This device can replace extractor.Owing to carry inconvenience, also make some professional for example the driver exempt with chewing oil-absorbing trouble.

Utility model design-calculated content

The design's basic structure form is to adorn two conduits on existing seal cover cap.One is used for calming the anger in container, and one is used for from container to external drainage.Be called air pipe and drainage tube.Drainage tube connects a sebific duct in container, the other end of sebific duct places container bottom; At the external sebific duct of container, the other end of this sebific duct leads in another container that receives liquid.Air pipe termination outside container device of calming the anger.As air pump, when the device of calming the anger can not pressurize continuously, can establish a check valve in the air pipe.

The design's using method is to flow out from hydraulic pipe with air pressure official post liquid.Replace toppling over extracting or with chewing absorption.After drainage success, cut off and the getting in touch of the device of calming the anger, and the opening encapsulation plug makes the container inner and outer air pressure identical, utilize siphon principle, the liquid in the container flows to the container that is positioned at lower continuously by drainage tube.

The embodiment of utility model

The design's embodiment such as Fig. 1-Fig. 3 or Fig. 4-Fig. 6.

Explanation to Fig. 1-Fig. 3:

This programme is applicable to small containers, as the bucket below 50 gallons.

Diagram: the valve nozzle 2 of air pipe 1, unidirectional conducting, valve nozzle hoop 3, air pipe captive nut 4 constitute the air pipe system.The drainage tube system that drainage tube 5, fluid card pipe 6, extract pipe clamp 7, drainage tube 5 captive nuts 8 constitute.Seal cover cap opens and closes bolt 9, seal cover cap 10.

Explanation to Fig. 4-Fig. 6:

This programme is applicable to tun.

Diagram is as Fig. 1-Fig. 3.

The advantage of utility model

New-type airtight lid for container by the design's basic structure form is made only adds two conduits at existing seal cover, adds two little conduit sealing caps when not making at ordinary times again, and processing and fabricating is convenient With low cost. Only need increase by an external pressurized air source during use, portable inflator for example is if small containers can be with the air bag of holding that uses on the sphygmomanometer. Can move and topple over, not use heavy extractor, the driver is also no longer with chewing oil suction, and is easy-to-use.

Claims

1, a kind of seal cover cap of liquid container is characterized in that being equipped with on the described seal cover cap two conduits.

2, a kind of seal cover cap as claimed in claim 1, it is characterized in that one of described conduit is an air pipe 1, the valve nozzle 2 of unidirectional conducting is housed in the described air pipe 1, fixes its position by valve nozzle hoop 3, air pipe captive nut 4 is fixed on air pipe 1 on the seal cover cap.

3, a kind of seal cover cap as claimed in claim 1 or 2, it is characterized in that one of described conduit is a drainage tube, it is that the end outer wall that fluid card pipe is positioned at container is an extract card pipe 7 that described drainage tube 5 is positioned at the outer end outer wall of container, and drainage tube captive nut 8 is fixed on drainage tube on the seal cover cap.
