Description
Technical field:
The utility model relates to a kind of structures to flap in folder muffling check valve.
Background technique:
The existing flap in folder muffling check valve is split type structure, and the flap of split type structure when in use, is tied
Structure is easily damaged, and stability is poor.
Utility model content:
The utility model is provided a kind of in folder muffling check valve to solve the above-mentioned problems of the prior art
The structure of flap.
Technical solution used by the utility model has: a kind of structure to flap in folder muffling check valve, including ontology,
The ontology is cone-shaped structure, is respectively equipped with first rotating shaft and the second shaft on the center position of the interior outer end face of ontology；
The ontology and first rotating shaft and the second shaft are integrally formed.
Further, the diameter of second shaft is greater than the diameter of first rotating shaft.
Further, the first rotating shaft is equipped with positioning step.
The utility model has the following beneficial effects: the utility model structure is simple, flap stability is good, is hardly damaged,
Using effect is good.
Detailed description of the invention:
Fig. 1 is the utility model structure chart.
Fig. 2 is the utility model application structure figure.
Specific embodiment:
The utility model will be further described below with reference to the accompanying drawings.
As depicted in figs. 1 and 2, a kind of structure to flap in folder muffling check valve of the utility model, including ontology 30, this
Body 30 is cone-shaped structure, is respectively equipped with first rotating shaft 31 and the second shaft on the center position of the interior outer end face of ontology 30
32.Ontology 30 and first rotating shaft 31 and the second shaft 32 are integrally formed.
The diameter of second shaft 32 is greater than the diameter of first rotating shaft 31.
