It is critical that the sealing shroud include be set in drainage duct body, be arranged at body end and with drainage duct end
It is provided with the flange of connection, and the cavity being connected with body inwall border set in vivo along water outlet direction in set, cavity
Otch is to form the petal formula structure being made up of petal type diaphragm, and the thickness of petal type diaphragm is tapered off shape by root to tip,
Body cooperatively forms the sealing structure of drainage duct with cavity.
It is preferred that, described otch is seamless cross recess.
It is preferred that, the material of described body, flange and cavity is rubber.
It is preferred that, the described root of petal type diaphragm and the thickness ratio of tip is 1.5-3.
It is preferred that, the external diameter of described body is identical with the internal diameter of drainage duct.
It is preferred that, described drainage duct includes inner and outer wall, and heat-insulation layer is provided between described inwall and outer wall.
The beneficial effects of the utility model are：The sealing shroud for being internally provided with cavity, draining are set up in drainage duct
When, under gravity, petal type diaphragm, which is opened, carries out draining, after current outflow, petal type diaphragm resilience, adjacent two petal
Formula diaphragm slitless connection is in sealing state, forms one-way cock, reduces room noise, prevents dust or peculiar smell in conduit from entering
Enter interior, it is ensured that indoor environment is quiet clean and tidy.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 for Fig. 1 A-A to sectional view.
In accompanying drawing, 1 represents body, and 2 represent drainage duct, and 2-1 represents inwall, and 2-2 represents outer wall, and 3 represent flange, 4 generations
Table petal type diaphragm, 4-1 represents root, and 4-2 represents tip, and 5 represent cavity, and 6 represent otch, and 7 represent heat-insulation layer.
Embodiment
Utility model is described further with specific embodiment below in conjunction with the accompanying drawings.
The utility model is related to a kind of noise reduction sealing shroud, and the sealing shroud is arranged in drainage duct 2, it is important to, sealing shroud
Including the body 1 being set in drainage duct 2, the flange 3 for being arranged at the end of body 1 and being connected with the end of drainage duct 2, and
Otch 6 is provided with the cavity 5 being connected with the inwall border of body 1 set along water outlet direction in body 1, cavity 5 to be formed
The petal formula structure being made up of petal type diaphragm 4, the thickness of petal type diaphragm 4 is tapered off shape, root by root 4-1 to tip 4-2
Portion's 4-1 thickness is thick, consolidates the bulk strength of petal type diaphragm 4, a small amount of retaining can be achieved, sealing is further enhanced, simultaneously
Because the water stored in cavity 5 produces deformation power to petal type diaphragm 4, and the tip 4-2 of petal type diaphragm 4 is relatively thin, easily occurs
Deformation carries out draining in open shape, after the completion of draining, and petal type diaphragm 4 recoils to reset condition, two adjacent petal type diaphragms 4 it
Between slitless connection, body 1 and cavity 5 cooperatively form the sealing structure of drainage duct 2, and cavity 5 shows non-return valve function, prevents
Backflow, and completely cut off the incoming interiors such as noise, peculiar smell.
It is preferred that, otch 6 is seamless cross recess, and cavity 5 is uniformly divided into four petal type diaphragms 4, entered by cross recess
One step enhances the deformation free degree of petal type diaphragm 4, is more conducive to draining or resilience sealing.
It is preferred that, the material of body 1, flange 3 and cavity 5 is rubber, and rubber has good elasticity and soundproof effect,
Isolate ambient noise, prevent the incoming interior of noise.
It is preferred that, the root 4-1 and tip 4-2 of petal type diaphragm 4 thickness ratio are 1.5-3, it is ensured that petal type diaphragm 4
Optimal elasticity is made it have while intensity, that is, is easy to draining, home position can be recoiled to again and forms sealing structure.
It is preferred that, the external diameter of body 1 is identical with the internal diameter of drainage duct 2, the cooperation of body 1 and conduit 2 is fitted together perfectly,
Strengthen sealing property.
