CN86201174U - Auto-start siphon with one-way valve - Google Patents

Abstract

One end of a general soft tube is sheathed with a one-way valve device and one end of a general soft tube can become a liquid inlet end, so that an auto-start siphon tube with one-way valve is formed. The liquid inlet end can be fed in a liquid containing container; user needs to continuously draw and shake the soft tube, which can make liquid fill with the soft tube; the starting process of siphon can be completed.

Description

Auto-start siphon with one-way valve

The utility model relates to a kind of syphon tube that extracts liquid.

Patent Office of the People's Republic of China's application number 85102606, classification bis F04F10/00, the contrivance name is called the contrivance of simple elastic capsule siphon, and during use, the user need have certain skill, and selecting for use of the material of leather bag is subjected to a lot of restrictions.This patent application openly before, the driver uses syphon tube, all exists working life short, or uses shortcoming such as inconvenience.The somebody puts a cap bag on the mouth of a plastic pipe, this cap bag is a bit of pipe, and its end can coincide preferably with people's lip, and the lip limit is difficult for gas leakage when making oil suction.The power that the lip containing that generation seals to tube mouth compressed when this cap bag just reduced driver's oil suction still needs inhale with mouth.

The purpose of this utility model is to the driver provides a kind of easy to use, the self-drive syphon tube of energy that the life-span is very long.

Realization of the present utility model: a flexible pipe, its end is adorned an one-way valve, makes fluid flow to the other end from this end, but can not swing to mobile.The tube device that this root has one-way valve has just become the utility model: the self-starting syphon tube.

This siphonal using method is like this: the oil absorbing end that one-way valve is housed is put in liquid container, and then, the pipe that makes this section stretch into container is shaken back and forth along the axial direction of itself.Because the inertial force of fluid, one-way valve makes the one-way flow of liquid in the pipe, and fluid just rises along pipe, and is full of whole pipe, has so just finished the starting process of siphon.

The good effect that the utility model brings is to produce a kind of easy to use, simple structure, and long-lived oil suction instrument, steam supply car driver or other often need the personnel of siphon liquid use from container.The utility model also provides the cap bag of a kind of plastic tube or other flexible pipe, and making just to become a syphon tube that can rise automatically after this cap bag on the hose proof.

Now contrast accompanying drawing and describe embodiment of the present utility model in detail.

Fig. 1 is a kind of embodiment's of the utility model a schematic representation.

Fig. 2 is the another kind of embodiment's of the utility model a schematic representation.

Self-starting syphon tube shown in Figure 1, the aperture of flexible pipe 1 have the enough length when using between 5mm to 40mm, this flexible pipe can be transparent, translucent or the plastic opaque pipe, also can be the oil resistant rubber pipe; One-way valve 2 can be a ball valve, also can be diaphragm valve.One-way valve 2 should have less liquid flowing resistance, that is: when liquid flows in one-way valve 2, the hydraulic radius of each liquid flow section, exceed less than the hydraulic radius of each liquid flow section of flexible pipe 1.Closing of this one-way valve can not rely on gravity, or elastic force attached help effect, but the various power that require to produce when the reverse flow of liquid stream can make valve close, And and oppositely can continue to close under the differential pressure action.This one-way valve can often be opened under no reverse differential pressure action, and this accomplishes easily, and ball valve (comprising plunger valve) in this way is as long as design the weight of ball (plunger) less than the buoyancy of ball; Diaphragm valve can make diaphragm have small elasticity in this way, and this elasticity can make diaphragm have the trend of unlatching.After one end of flexible pipe 1 was loaded onto one-way valve 2, B became liquid entering hole, and A becomes liquid outlet, and this has just constituted thing of the present invention: the self-starting syphon tube.

Shown in Figure 2, also be a self-starting syphon tube, the numeral identical with Fig. 1, the title at the position of bis indication is same as Fig. 1.

Syphon tube shown in Figure 2, the endoporus of its flexible pipe 1 is with a spring 3, and the external diameter of spring 3 is suitable with the internal diameter of pipe.The purpose that puts this spring is to make the pipe can be not flat, also is to make flexible pipe to stretch with comparalive ease.

No matter from Fig. 1, still can find out obviously that from Fig. 2 the siphonal external form of self-starting becomes an elongated tubular, the thickest position of this long tube is at pipe end, and promptly inlet port begins, along ， And within the 10cm of pipe range direction and within this 10cm, one-way valve is housed.

Also can find out from Fig. 1, Fig. 2: a flexible pipe puts a cap bag (this cap bag should be an one-way valve, and the outlet end of cap bag can be enclosed within on the plastic tube) and also constitutes thing of the present invention.

With a general flexible pipe, its end puts a check valve apparatus ， And makes this end become liquid feeding end, and this has just formed a self-starting syphon tube.

This liquid feeding end is sent to liquid container, constantly draw and tremble flexible pipe, just can make liquid be full of flexible pipe, finished the starting process of siphon.
