The utility model relates to a tee one-way valve, for controlling the direction of transferred fluid, which is suitable for medical devices. The tee one-way valve comprises three pipe orifices, while two pipe orifices are provided with a one-way valve, and the one-way valve of one pipe orifice is reversely mounted, wherein the one-way valve is provided with a valve chamber in which a separation membrane is arranged, the middle of the separation membrane is provided with a membrane through hole, one side of the separation membrane is provided with a liquid outlet correspondingly, the another side of the separation membrane is provided with a liquid inlet correspondingly to the periphery of the membrane through hole, and the middle part is provided with a protrusion having a clearance fit with the membrane through hole. The tee one-way valve has simple and reasonable structure and can be selectively installed, which can be controlled by the one-way valve and the one-way valve of reversed installment to automatically and quickly transfer fluid. The tee one-way valve can accurately control the fluid of low and high speed, having simple, fast, safe and reliable use.
Description
Technical field
The utility model relates to a kind of threeway one-way valve, is used for the direction control of convection cell transfer process, is particularly suitable for being applied on the medical apparatus.
Background technique
In order better the control on the fluid travel direction of multidirectional transfer to be prevented the fluid reflux in a certain loop again, there have been a lot of methods on the market now, for example existing three way cock, really the accurate transfer of fluid that has been very good realization, but need make complicated operationization with hand rotary knob on demand.Also having the one-way valve that occurred afterwards, all is the problem that has solved flow velocity fluid transmission faster, but just can't play a role when flow velocity is low, makes its use limited.
The model utility content
The purpose of this utility model is to provide a kind of threeway one-way valve, and is simple and reasonable, can realize accurate control to the very fast slower fluid of flow velocity, efficient and convenient, safe and reliable, use, easy to operate.
Threeway one-way valve described in the utility model has three mouths of pipe, has on two mouths of pipe in its three mouths of pipe one-way valve is installed, and the one-way valve on one of them mouth of pipe is oppositely installed.
The connected parts of one-way valve can be the split structure, also can be integral structure.
Described threeway one-way valve, its one-way valve has valve pocket, valve pocket is built-in with isolation diaphragm, the middle part of isolation diaphragm is provided with the diaphragm through hole, one side correspondence of isolation diaphragm is provided with liquid outlet opening, the opposite side of isolation diaphragm has the inlet opening of corresponding diaphragm through hole periphery, and the middle part is provided with the projection with diaphragm through hole interference fit.
The programmable diameter of inlet opening is less, is circumferential distribution, can distribute 2-8.
The utility model threeway one-way valve, simple and reasonable, install and use by selection, by one-way valve and the oppositely control of the one-way valve of installation, the requirement of fluid transfer can be satisfied automatically apace, accurate control can be realized the very fast slower fluid of flow velocity, efficient and convenient, safe and reliable, use, easy to operate.
Description of drawings
Fig. 1, the utility model one example structure schematic representation.
Among the figure: 1, import and export 2, valve casing 3, liquid entering hole 4,13, inlet opening 5,14, projection 6,10, diaphragm 7, liquid outlet opening 8,15, diaphragm through hole 9, fluid flap 11, feed liquor flap 12, inlet opening.
Embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in Figure 1, threeway one-way valve described in the utility model has three mouths of pipe on the valve casing 2, has in its three mouths of pipe on two mouths of pipe in bottom and left side one-way valve is installed, and the one-way valve on the mouth of pipe in one of them left side is oppositely installed.
With the one-way valve on the lower nozzle is example, and its structure is described, one-way valve has valve pocket, valve pocket is built-in with isolation diaphragm 6, preferably made by flexible material, the middle part of isolation diaphragm 6 is provided with diaphragm through hole 8, and a side correspondence of isolation diaphragm 6 is provided with liquid outlet opening 7, the opposite side of isolation diaphragm 6 has the inlet opening 4 of corresponding diaphragm through hole 8 peripheries, and the middle part is provided with the projection 5 with diaphragm through hole 8 interference fit, and inlet opening 4 programmable diameters are less, are circumferential distribution, can distribute 2-8,9 is the fluid flap.
Working principle:
When being negative pressure in the valve casing 2, the isolation diaphragm 6,10 at liquid outlet opening 7 and inlet opening 12 places all relies on the corresponding end of valve casing 2, and at liquid outlet opening 7 one ends, diaphragm through hole 8 is shut by the projection 5 of valve casing 2 corresponding end, inlet opening 4 is also shut by isolation diaphragm 6, i.e. liquid outlet opening 7 sealings; And at inlet opening 12 1 ends, diaphragm through hole 15 aligns with liquid entering hole 3 on valve casing 2 corresponding end, and the inlet opening 13 on the feed liquor flap 11 is opened simultaneously, and promptly inlet opening 12 is unimpeded.On the contrary, when being malleation in the valve casing 2, the isolation diaphragm 6,10 at liquid outlet opening 7 and inlet opening 12 places all relies on fluid flap 9 and feed liquor flap 11 ends, at liquid outlet opening 7 one ends, diaphragm through hole 8 aligns with liquid outlet opening 7, and the inlet opening 4 on valve casing 2 corresponding end is opened simultaneously, and promptly liquid outlet opening 7 is unimpeded; And at inlet opening 12 1 ends, diaphragm through hole 15 is shut by the projection on the feed liquor flap 11 14, and inlet opening 13 is also shut by isolation diaphragm 10, i.e. inlet opening 12 sealings.
