The utility model is characterized in that a single-way ducting device is arranged in a flow guiding channel of the first or the second pipeline connecting piece. The utility model has the advantages of simple structure and low cost, and the single-way ducting fluid pipeline connector is provided with a partition board and a valve so as to realize the functions of a single-way valve.
Description
Affiliated technical field
The utility model relates to a kind of connector for fluid carrying conduits, relates in particular to a kind of unidirectional conducting connector for fluid carrying conduits.
Background technique
Present connector for fluid carrying conduits only uses as connecting tube, function singleness.Fluid (liquid or gas) pipe-line system often needs to control the flow direction of fluid because of function, for example require the fluid can only one-way flow.The way of now usual realization one-directional fluid flow is to install an one-way valve additional, achieves the goal though do like this, and cost is higher, and for the occasion of some compact structures, the installation of one-way valve also is restricted.
Summary of the invention
In order to overcome existing connector for fluid carrying conduits deficiency, purpose provides a kind of unidirectional conducting connector for fluid carrying conduits, can not only play connecting tube, also has the function of unidirectional conducting.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of unidirectional conducting connector for fluid carrying conduits, comprise first pipe joint, second pipe joint, connected member, first pipe joint is connected with a side pipe road, second pipe joint is connected with the opposite side pipeline, connected member connects first pipe joint, second pipe joint and connecting pipe is characterized in that: be provided with Device in one-way on state in the guide channel of first or second pipe joint.
Described first or the junction point of second pipe joint be provided with seal ring.
Described Device in one-way on state comprises dividing plate and valve, and dividing plate middle part is provided with pod apertures and is fixedly connected on the guide channel of link and only stays pod apertures to connect, and valve is movably hinged on dividing plate and suitable can being sealed and matched with pod apertures.
The fitting surface of valve and pod apertures is the inclined-plane, and the direction that the true dip direction on inclined-plane and fluid flow backwards is identical, rotating valve when fluid flows backwards and confined bed discharge orifice.
The shape of described corresponding pod apertures and valve includes but not limited to be square, circular, the cydariform of circular arc on one side.
The beneficial effects of the utility model are, connector for fluid carrying conduits is provided with dividing plate and valve, has realized the function of one-way valve, and simple in structure, and cost is low.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Consult Fig. 1 to Fig. 9, this example is that the pipeline that is applied to the injection water of massaging bathtub connects, and requires injection water that the refluence phenomenon can not be arranged.A kind of unidirectional conducting connector for fluid carrying conduits,-comprise first pipe joint 1, second pipe joint 2, connected member 3, first pipe joint 1 is connected with a side pipe road, second pipe joint 2 is connected with the opposite side pipeline, and connected member 3 connects first pipe joint 1, second pipe joint 2 and connecting pipe.Described first pipe joint 1, second pipe joint 2 and connected member 3 all adopt injection-moulding plastic, and the junction point of first or second pipe joint is provided with seal ring 4.In the guide channel of first or second pipe joint, be provided with Device in one-way on state 5.This example is provided with Device in one-way on state 5 in the guide channel of first pipe joint 1.
Described Device in one-way on state comprises dividing plate 51 and valve 52, and dividing plate 51 middle parts are provided with and on one side be the square pod apertures 511 of circular arc, and utilizes adhesive to be adhered on the guide channel of first pipe joint 1 and only stay pod apertures 511 perforations.Valve 52 is sealed and matched with pod apertures 511, and is movably hinged on dividing plate 51, and valve 52 can rotate around its hinge 521.Valve 52 is the inclined-plane with the fitting surface of pod apertures 511, and the true dip direction on inclined-plane is identical with the direction that fluid flows backwards, rotating valve 52 during the fluid refluence and confined bed discharge orifice 511.
The shape of described corresponding pod apertures 511 and valve 52 also can be circle, cydariform or its distortion.
This example mechanism is as follows, and after the connector installation, pipeline is communicated with.When the current forward flow, current are washed valve 52 open, and current pass through smoothly.If the pressure of water inlet reduces, when the hydraulic pressure in the connector negative pressure occurs greater than pressure of supply water, confined bed discharge orifice 511 backflow rotating valve 52 appears and in the water in the connector, negative pressure is big more, the suffered pressure of valve 52 is also big more, then valve 52 cooperate closely more with pod apertures 511, guarantee to flow backwards by current.
Above-described specific embodiment only is the utility model preferred embodiment, and the equivalent arrangements of being done according to the utility model claim all should be technology of the present utility model and contains such as.
