Description

Technical Field

[0001] The utility model relates to the field of building drainage equipment, in particular to a check valve for preventing a side wall type floor drain from emitting odor. Background Art

[0002] The side wall type floor drain is a type of floor drain widely used in tropical areas. After installation, the horizontal drainage pipe extends out of the wall and is connected to the water trap. The construction cost is low. However, since there is not always water on the ground, the side wall type floor drain cannot drain water frequently. The water trap will dry up without a water seal, and the sewer odor can be released through the side wall type floor drain, polluting the indoor environment, irritating the sense of smell, and making people feel annoyed.

[0003] There are many cockroaches in the sewer, and the humid environment is conducive to the breeding of moth flies, which enter the room through the side wall floor drain and spread diseases. Also, if the sewer overflows, the sewage will flow back from the side wall floor drain into the room.

[0004] "Physical experiments have shown that the mass diffused from the side with higher density to the side with lower density per unit time is proportional to the product of the density gradient and the area of ​​the surface" (General Physics, Shanghai Higher Industrial School Physics Writing Group). A check valve is a mechanical device that can both expel fluid in the forward direction and prevent fluid from passing in the reverse direction. Utility Model Content

[0033] Example:

[0034] Figure 1 The schematic diagram of the anti-odor valve shows an anti-odor valve 1 arranged in a side wall floor drain, which includes a side wall floor drain 1, a drain pipe 2 and an anti-odor valve 3. In this case, the side wall floor drain 1 and the drain pipe 2 are plastic products of DN50 specification, and the anti-odor valve 3 is arranged in the DN50 side wall floor drain;

[0035] The deodorizing valve 3 comprises a valve seat 31, a flap door 32, a silicone ring 33 and a stainless steel wire shaft 34; the valve seat 31 comprises a seat cover 311, two seat feet 312, a silicone ring seat 313, a seat ring 314, a ditch 315, a bearing plate 316, a pair of seat bearings 317, a protruding point 318 and a flow port 319; the flap door 32 comprises an upper bearing plate 321 and a door plate 322 at the bottom that closes the flow port 318; the bearing plate 321 comprises side bearings 323 on both sides and a middle bearing 324 in the middle, the side bearing 323 comprises an opening 325 to the left, and the middle bearing 324 comprises an opening 325 to the right The opening 326, the left opening 325 and the right opening 326 constitute a bearing hole 327; the silicone ring 33 includes a rubber sleeve 331 and a plate edge 332; the stainless steel wire shaft 34 is passed through the bearing hole 327 of the flap door 32, and then the two ends of the stainless steel wire shaft 34 are pressed into the seat bearing 317 of the valve seat 31, and the protruding point 318 will prevent the stainless steel wire shaft 34 from detaching from the seat bearing 317, that is, the flap door 32 is installed on the valve seat 31; the silicone ring 33 is put on the silicone ring seat 313, and the assembly of the deodorizing valve 3 is completed.

[0036] The odor-proof valve 3 is inserted into the bell mouth of the side wall type floor drain 1, and the two base feet 312 stand on the flat bottom of the side wall type floor drain 1. The silicone ring 33 fills the gap between the odor-proof valve 3 and the side wall type floor drain 1. The flap door 32 closes the flow port 319 under the action of gravity, which greatly reduces the area of ​​the passage and prevents the odor of the sewer and pests such as cockroaches and moth flies from entering the room. When there is water on the ground, the water will flow into the side wall type floor drain 1, push open the flap door 32, flow into the drain pipe 2, and drain into the sewer. After drainage, the flap door 32 closes the flow port 319 again under the action of gravity.
