Abstract

The utility model relates to a liquid siphon, which is characterized in that two positive and negative one-way valves which are arranged in a casing body are jointly connected with an air cell, wherein, the negative one-way valve is connected with a three-way or a four-way through a connecting pipe. The utility model has the advantages of simple and compact structure, rapid and convenient diversion of liquid, and the utility model can be used for various liquids in various situations.

Description

Liquid siphon

The utility model relates to a kind of liquid siphon device that utilizes the siphon principle transfer liquid.

What at present, the transfer of big capacity liquid is adopted is electric pump; It generally is the various siphon devices that utilize siphon principle to manufacture that a spot of liquid shifts, as Chinese utility model patent " siphon-pump " (patent No. is 88220888.8), it utilizes the swelling pressure transfer liquid of air bag, but because the corrosivity of liquid causes the damage of air bag inevitably.Find also that by retrieval some utilize piston to make in the pipeline and produce the Patent project that negative pressure is carried out siphon in addition, its cost is high and fragile.

The purpose of this utility model is to provide fast liquid siphon device easily of a kind of simple in structure, transfer liquid.

The purpose of this utility model is achieved in that

Be contained in positive and negative two one-way valves common air bag that connects outside shell in the housing, wherein anti-one-way valve connects threeway or four-way by connecting tube.

Positive one-way valve has return spring and directly is communicated with air, or is communicated with four-way by connecting tube; In addition, a pipe valve is housed on the drain pipe.

The utility model has the advantages that:

Connecting tube, liquid inlet pipe, drain pipe all can adopt transparent hose to manufacture, and be visual good, is difficult for making the liquid corrosion air bag.Housing and interior one-way valve, pipe valve, threeway, four-way thereof all can be suppressed by plastics, and be cheap.Utilize the pipe valve of drain pipe can prevent effectively that liquid from shifting the weeping when finishing.The utility model is simple and reasonable, is applicable to the conveying of occasions such as family, factory, breed, laboratory, fleet to water, gasoline, diesel oil, machine oil, toxic liquid, chemical reagent, is particularly useful for driver's oiling in fuel tank at any time.

Description of drawings:

Fig. 1 is a structural representation sketch of the present utility model;

Fig. 2 is another embodiment's of the utility model a structural representation sketch.

Below in conjunction with accompanying drawing the utility model embodiment is further described:

Embodiment 1: referring to Fig. 1, be contained in the positive one-way valve 5 in the housing 3, anti-one-way valves 2 common with air bag 6 connections (here one-way valve just with counter be relative air bag).Position spring 4 once on the positive one-way valve, and positive one-way valve directly is being communicated with air; For chemical gas, corrosive gas or liquid, also can connect a pipe at positive one-way valve, introduce in the recovering container, avoid harmful and pollute.Anti-one-way valve is communicated with threeway 10 by connecting tube 1, and two mouths in addition of threeway are communicated with drain pipe 9 that pipe valve 8 is housed and liquid inlet pipe 11 respectively.Be connected to storage liquid container 7,12 under drain pipe and the liquid inlet pipe respectively.

Embodiment 2: referring to Fig. 2, only be on embodiment 1 basis, threeway makes four-way 14 into, connects a connecting tube 13 to four-way in the outlet of positive one-way valve, and other all is same as embodiment 1.

Working principle of the present utility model is: turn-off pipe valve, liquid inlet pipe inserts below the storage liquid container liquid level, at this moment extruding gasbag.For the structure shown in the embodiment 1, air before connecting tube and liquid inlet pipe and the drain pipe pipe valve drains into positive one-way valve through anti-one-way valve, promote return spring again and discharge, make and form negative pressure in connecting tube, the liquid inlet pipe, liquid arrives drain pipe pipe valve place along liquid inlet pipe.The utility model all can be manufactured by the transparent plastic of corrosion protection except that air bag, and is visual good.When liquid arrives pipe valve, can open pipe valve, inject to the storage liquid container according to siphon principle liquid.To embodiment 2, during the squish capsule, air discharges by liquid inlet pipe through positive one-way valve, has bubble to produce in the storage liquid container.When unclamping air bag, liquid inlet pipe, connection inner air tube arrive air bag through reverse one-way valve, the interior negative pressure that produces of its pipe, and liquid enters in the liquid inlet pipe, and extruding like this is unclamped several times, and liquid can arrive pipe valve, can realize that liquid shifts.

Claims (3)

1, a kind of liquid siphon device, constitute by air bag, connecting tube, threeway or four-way, one-way valve, pipe valve, liquid inlet pipe, drain pipe, threeway or four-way connect liquid inlet pipe and drain pipe, it is characterized in that: be contained in positive and negative two one-way valves common air bag that connects outside shell in the housing, wherein anti-one-way valve connects threeway or four-way by connecting tube.

2, liquid siphon device according to claim 1 is characterized in that: positive one-way valve has return spring and directly is communicated with air, or is communicated with four-way by connecting tube.

3, liquid siphon device according to claim 1 and 2 is characterized in that: a pipe valve is housed on the drain pipe.
