Abstract
This utility model relates to anti-pollution field, is specially a kind of reverse-filling Odor-returning preventing direct exhaust device.This device includes: clip, inner sleeve, flat duckbilled, concrete structure is as follows: clip, inner sleeve, flat duckbilled are split combination structure, one end of flat duckbilled is arranged between clip and inner sleeve, one end of flat duckbilled is strutted by inner sleeve, and assemble with clip combination, the other end of flat duckbilled arranges closing in section.When this utility model device is installed on discharge tube, upper flange and sealing ring by clip are reliably installed in discharge tube, make outside clip with discharge tube favorable sealing property.When External Force Acting is the biggest, flat duckbilled is the tightst with the combination of clip, inner sleeve, flat duckbilled will be caused to come off because of drain discharge is excessive.It addition, flat duckbilled only when draining, blowdown stress open, draining, blowdown terminate rear Natural closure, will completely cut off with discharge tube, it is achieved effectively reverse-filling Odor-returning preventing inside clip.
Description
Technical field
This utility model relates to anti-pollution field, is specially a kind of reverse-filling Odor-returning preventing direct exhaust device.
Background technology
The sewage drainage pipe of floor drain of the prior art, pond or toilet drainage position is anti-returns dirty structure, uses trap
Tubular construction, during sewer, dirt also remains in pipe bent position, causes drain pipe to block, and makes sewage overflow, and makes filter bowl the most not
Can be fully erased by dirt, trap can only be opened and clear up, just trap place is narrow, is not easily cleaned.
Existing self-closing odour-proof floor drain, has been mainly characterized by water when passing through, has opened under the action of gravity of water, anhydrous logical
Out-of-date, utilize product self to close against property, thus play deodorant, prevent returning water effect, but its discharge capacity is less, runs into a large amount of draining feelings
During condition, lower water is relatively slow, brings bigger puzzlement to modern house life, and and floor drain drain gully between sealing property the best,
Foul smell in downcomer easily overflows.
Utility model content
The purpose of this utility model is to provide a kind of reverse-filling Odor-returning preventing direct exhaust device, this apparatus structure advantages of simple,
Blowdown is smooth and easy, reverse-filling Odor-returning preventing is effective, and can effectively prevent from coming off.
The technical solution of the utility model is:
A kind of reverse-filling Odor-returning preventing direct exhaust device, this device includes: clip, inner sleeve, flat duckbilled, and concrete structure is as follows:
Clip, inner sleeve, flat duckbilled are split combination structure, one end of flat duckbilled be arranged at clip and inner sleeve it
Between, one end of flat duckbilled is strutted by inner sleeve, and assembles with clip combination, and the other end of flat duckbilled arranges closing in section.
Described reverse-filling Odor-returning preventing direct exhaust device, closing in section is vertical structure or the bending structure of Natural closure.
Described reverse-filling Odor-returning preventing direct exhaust device, the upper outside of clip arranges upper flange, the outside of clip, Yu Shangfa
Blue sealing ring arranged below, the lower inside of clip arranges lower snap ring.
Described reverse-filling Odor-returning preventing direct exhaust device, the outside of clip is by upper flange and discharge tube clamping.
Described reverse-filling Odor-returning preventing direct exhaust device, the outside of clip is coordinated with discharge tube by sealing ring.
Described reverse-filling Odor-returning preventing direct exhaust device, the inner side of clip is corresponding with inner sleeve by lower snap ring, by inner sleeve,
Lower snap ring makes one end of flat duckbilled be installed in inside clip.
Advantage of the present utility model and providing the benefit that:
When this utility model device is installed on discharge tube, upper flange and sealing ring by clip are reliably installed on discharge
In pipeline, make outside clip with discharge tube favorable sealing property.Simultaneously as flat duckbilled of quality of rubber materials can deform,
One end of flat duckbilled is strutted by inner sleeve, and assembles with clip combination.When External Force Acting is the biggest, flat duckbilled and clip,
The combination of inner sleeve is the tightst, flat duckbilled will be caused to come off because of drain discharge is excessive.It addition, flat duckbilled is only row
When water, blowdown, stress is opened, and draining, blowdown terminate rear Natural closure, will completely cut off with discharge tube, it is achieved the most anti-inside clip
Pour in down a chimney Odor-returning preventing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is an embodiment side view of Fig. 1.
Fig. 3 is another embodiment side view of Fig. 1.
In figure, 1 clip；11 upper flanges；12 sealing rings；13 times snap rings；2 inner sleeves；3 flat duckbilleds；31 closing in sections.
Detailed description of the invention
As shown in Figure 1-Figure 3, this utility model reverse-filling Odor-returning preventing direct exhaust device, specifically include that clip 1, inner sleeve 2, flat
Sheet duckbilled 3 etc., concrete structure is as follows:
Clip 1, inner sleeve 2, flat duckbilled 3 are split combination structure, and one end of flat duckbilled 3 is arranged at clip 1 and interior
Between set 2, one end of flat duckbilled 3 of quality of rubber materials is strutted by inner sleeve 2, and assembles with clip 1 combination.Flat duckbilled 3
The other end arranges closing in section 31, and closing in section 31 is vertical structure (Fig. 2) or bending structure (Fig. 3), and when not using, flat duckbilled 3 is certainly
So Guan Bi, plays the effect of reverse-filling Odor-returning preventing.
The upper outside of clip 1 arranges upper flange 11, the outside of clip 1, in upper flange 11 sealing ring arranged below 12, card
The lower inside of hoop 1 arranges lower snap ring 13.Reliable installation, by upper flange 11 and discharge tube clamping, is played in the outside of clip 1
Effect.The outside of clip 1 is coordinated with discharge tube by sealing ring 12, plays the sealing function outside clip 1.Clip 1
Inner side is corresponding with inner sleeve 2 by lower snap ring 13, makes one end of flat duckbilled 3 be installed in clip 1 by inner sleeve 2, lower snap ring 13
Inner side, plays flat duckbilled 3, inner sleeve 2 and the close-fitting effect of clip 1, it is possible to effectively prevent coming off of flat duckbilled 3.
