The model utility content
At the prior art above shortcomings, the technical problem that the utility model solves is: the solid impurity that how to provide a kind of block piece to be difficult for being mingled in the liquid blocks, and the one-way valve structures of long service life.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of one-way valve that adopts the outlet valve done of spin is characterized in that, comprises one-way valve body cylindraceous and is arranged on the intrinsic spin of one-way valve, and the internal diameter of one-way valve body is greater than the diameter of spin; End at the one-way valve body is provided with inwardly uncovered water intake, and the cross section of described water intake is circular, and the open-mouth end internal diameter of water intake is greater than the diameter of spin, and the closing in end internal diameter of water intake is less than the diameter of spin; The other end at the one-way valve body is provided with water outlet, and described water outlet is provided with the spin barrier rib that can stop spin to pass through water outlet.
Wherein, the quantity of described spin barrier rib is 2 to 6.
Compared to existing technology, the utlity model has following beneficial effect:
1, the utility model adopts spin, because spheroid has fabulous easy rollability in one-way valve body cylindraceous, be stuck in situation between one-way valve body and the spin even solid impurity occurs, thereby when spin is subjected to the working fluid applied pressure, just can roll and make the solid impurity landing, therefore the middle tablet that adopts the utlity model has the advantage that can prevent that block piece from being blocked by solid impurity as the structure of block piece compared to existing technology.
2, the utility model does not use spring members, and the spin by sphere-like is set, inwardly uncovered water intake and water outlet with spin barrier rib have been realized the non-return valve function that prevents that liquid from flowing backwards equally, therefore compared with prior art have simple in structure, the life-span long and be convenient to the advantage of manufacturing.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to Fig. 1, a kind of one-way valve that adopts the outlet valve done of spin comprises one-way valve body 1 cylindraceous and the spin 2 that is arranged in the one-way valve body 1, and the internal diameter of one-way valve body 1 is greater than the diameter of spin 2, and spin 2 is the rubber material;
End at one-way valve body 1 is provided with inwardly uncovered water intake 7, and the cross section of described water intake 7 is circular, and the open-mouth end internal diameter of water intake 7 is greater than the diameter of spin 2, and the closing in end internal diameter of water intake 7 is less than the diameter of spin 2;
The other end at one-way valve body 1 is provided with water outlet 3, described water outlet 3 is provided with and can stops spin 2 by the spin barrier rib 8 of water outlet 3, particularly, as shown in Figure 2, can be provided with a plurality of spin barrier ribs 8 along water outlet 3 diametric(al)s, leave the space of passing through for liquid between the spin barrier rib 8, the quantity of spin barrier rib 8 can be set to 2 to 6.
Need to prove, connecting head 4, revolve retaining nut 5, seal ring 6 and other parts that does not relate to, do not belong to the utility model and improve, all can adopt existing mature technology, do not repeat them here.
Working principle of the present utility model and concrete working procedure are as follows:
When liquid flows into one-way valve body 1 from water intake 7, spin 2 is subjected to the influent applied pressure and moves to water outlet 3 directions of one-way valve body 1, the spin barrier rib 8 that final spin 2 is arranged on the water outlet 3 stops and stop motion, because the internal diameter of one-way valve body 1 is greater than the diameter of spin 2, and leave the space of passing through for liquid between the spin barrier rib 8, therefore, this moment, one-way valve body 1 inside formed the flow channel that passes through for liquid, liquid can successfully flow into from water intake 7, flows out from water outlet 3 again; When liquid flows into one-way valve body 1 from water outlet 3, spin 2 is subjected to the influent applied pressure and moves to water intake 7 directions of one-way valve body 1, because water intake 7 is inwardly uncovered, and, the open-mouth end internal diameter of described water intake 7 is greater than the diameter of spin 2, the closing in end internal diameter of water intake 7 is less than the diameter of spheroid spin 2, so spin 2 finally can be stuck in the open-mouth end of water intake 7 and close up between the end and stop up water intake 7 fully, and liquid flow path is turned off.
