Description
Technical field
The utility model relates to a kind of unidirectional water outlet pipe fitting.
Background technique
In the connection of water pipe, the water in water pipe refluxes, and conventionally can use one-way valve, and the internal structure of one-way valve is comparatively complicated, and later maintenance comparatively bothers, and the cost of one-way valve is also higher simultaneously, and therefore its popularization is subject to certain restriction.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of unidirectional water outlet pipe fitting, and this device can complete the unidirectional outflow of current, avoids refluxing, and structure is comparatively simple, and cost is comparatively cheap.
For addressing the above problem, the utility model adopts following technological scheme:
A kind of unidirectional water outlet pipe fitting, comprise the pipe fitting body that PVC plastics are made, in described pipe fitting inner body wall, there is one and extended the back-up ring obtaining by pipe fitting bulk material, described pipe fitting body interior, the right side that is positioned at back-up ring first back-up ring that has been threaded, between described back-up ring and the first back-up ring, be provided with the unidirectional cup of a taper, described unidirectional cup is provided with several permeable holes near large end position place, the left end of described back-up ring is bonded with seal ring, described seal ring middle part has a through hole, and the diameter of described through hole is less than the residing diameter of a circle of described permeable hole.
As preferred technological scheme, on the outer wall of described unidirectional cup, be bonded with rubber layer, by this rubber layer, can increase the sealing between unidirectional cup and seal ring.
As preferred technological scheme, the small end position of described unidirectional cup has the first through hole, and seal the end cap of this first through hole, described end cap is threaded with unidirectional cup, the diameter of described unidirectional cup small end is less than the diameter of through hole, by this structure, can facilitate two-way circulating of this device, for the many a kind of selection modes of user.
As preferred technological scheme, the large end part of described unidirectional cup fits with the inwall of pipe fitting body, bonding to cup in the time being subject to the thrust of water, slip that can be smooth-going.
The beneficial effects of the utility model are: this device is in the time of draining, and current enter from left side, then under thrust, unidirectional cup departs from seal ring, then current are discharged through permeable hole, and in the time there is adverse current, unidirectional cup is moved to the left under the effect of current, form sealing with seal ring, avoid refluxing, the structure of this device is comparatively simple, and cost is comparatively cheap simultaneously, install more for convenience, is applicable to promoting the use of.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Embodiment
