Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: a deodorant anti-clogging check valve comprises a first baffle plate 1, a first fixing plate 2, a telescopic fold 3, a valve body 4, a second fixing plate 5, a second baffle plate 6, a fixing hole 7, an inclined plane 8, a hinge 9, a first spring 10, a support rod 11, an annular lifting plate 12, an inner groove 13, a second spring 14, a limiting ring 15 and a sealing ring 16, wherein the inner wall of one side of the valve body 4 is provided with the support rod 11, the outer wall of one side of the support rod 11 is rotatably connected with the first baffle plate 1 and the second baffle plate 6 through the hinge 9, the first baffle plate 1 is positioned at one side of the second baffle plate 6, the first spring 10 is respectively arranged between the first baffle plate 1 and the second baffle plate 6 and the support rod 11, the limiting ring 15 is arranged at a position close to one side of the first baffle plate 1 and the second baffle plate 6 on the inner wall of one side of the valve body 4, the inner groove 13 is arranged at a position close to one side of the first baffle, be provided with second spring 14 on the one side inner wall of inside groove 13, the one end of keeping away from inside groove 13 on second spring 14 is provided with annular lifter plate 12, plays spacing effect to first baffle 1 and second baffle 6, guarantees the sealed compactness of check valve.

Furthermore, an inclined surface 8 is formed on the outer wall of one side of the first baffle plate 1 and the second baffle plate 6, and a sealing ring 16 is arranged at a position, close to the inclined surface 8, on the outer wall of one side of the limiting ring 15, so that the sealing performance is further improved, and the deodorization capacity is improved.

Further, be provided with first fixed disk 2 on the one side outer wall of valve body 4, be provided with second fixed disk 5 on the opposite side outer wall, be convenient for install the check valve on the sewer pipe.

Furthermore, four fixing holes 7 are uniformly formed in the outer wall of one side of the first fixing disc 2 and the outer wall of one side of the second fixing disc 5.

Further, be provided with flexible fold 3 between first baffle 1 and the second baffle 6, flexible fold 3 adopts the rubber material, is convenient for protect the region between first baffle 1 and the second baffle 6.

Further, the first baffle 1 and the second baffle 6 are both in a semicircular structure.

Furthermore, the angle between the top of the limiting ring 15 and the valve body 4 is 150 degrees, so that the gathering impact force of water flow is improved.
