In embodiment, in order to further reduce the volume of whole device, preferably laterally branch pipe converges lateral dilatation pipe 14 in snail shell
It shape and is fixed as one with longitudinally connected pipe 12.
Structure and working principle above with respect to tee tube are by the entitled preset bushing type list standpipe before the applicant
The patent disclosure of rotational flow silencing triplet attachment device Patent No. (201721490961.0), details are not described herein again.
In the positions such as balcony or kitchen, since the waste water on floor is less or user does not have to water for a long time and cause not having
When having waste water to enter water seal storage area, in order to guarantee there is waste water always in water seal storage area, it is arranged on the tube wall of tee tube
There is one or more moisturizing connector 4, enters moisturizing connector 4 in order to facilitate waste water, moisturizing connector 4 is in the way of diagonally downward
It is connected on the tube wall of tee tube, self-complementary water pipe 5 is connected on each moisturizing connector 4, the lower end of self-complementary water pipe 5 passes through drainage layer
It is protruded into after 11 in water seal storage area 3.
In use, the waste water in water seal storage area 3 constantly evaporates and does not have new waste water to enter water seal water storage on floor
When in area 3, upstairs the waste water of user is fallen out of upper drainpipe 18, and the waste water fallen is flowed down along the tube wall of tee tube,
Entered in water seal storage area 3 by self-complementary water pipe 5, to moisturizing is carried out in water seal storage area 3, can guarantee water seal storage area in this way
Water seal is formed in 3 always.
It is connected on tee tube and lengthens pipe plug reducing connecting tube 15, lengthen pipe plug reducing connecting tube 15 includes 16 He of inner tube again
The outer top of the outer tube 17 being fixed as one with inner tube 16, the outer tube 17 has outer limit installation boss, in inner tube 16
Wall bottom has interior positive stop lug boss, and the hole section which encloses is upper collector nozzle, lengthens pipe plug reducing connecting tube 15
Drainpipe 18 is fixed in inner cavity.It can be convenient for pipeline construction in this way, the reliable effective connection length for guaranteeing pipeline prevents
Drainpipe 18 drops.This structure is also by the same patent disclosure before above-mentioned the applicant.
In fact, Drainage Section can be tee tube or common water pipe etc., specific structure according to specific installation situation and
It is fixed.
It is fixed with noise reduction connector 6 on the lower cavity wall of sealing built-in pipe 1, cyclone 7 is installed in noise reduction connector 6,
Spinning disk 8 is installed in cyclone 7, forms silencing cavity 9 between the inner wall of noise reduction connector 6 and the outer wall of cyclone 7, noise reduction connects
The inner cavity lower part of clutch 6 is fixed with lower drainpipe 10.Silencing cavity 9 can reduce noise caused by water flow, improve use relax
Adaptive.
Connect under in fact, section can for cyclone or common water pipe etc., specific structure according to specific installation situation and
It is fixed.
In order to further improve the waterproof performance of the device, the upper inside wall of sealing built-in pipe 1 is connected with water retaining brim 19,
The upper end of cyclone 7 is located in the gap between 1 inner wall of water retaining brim 19 and sealing built-in pipe, and waste water is fully entered by water retaining brim
In cyclone, avoids waste water and enter in the gap between embedded water stop built-in pipe and noise reduction connector.
In the above-described embodiments, water stopping rib 20 is connected on the outer wall of sealing built-in pipe 1.Sealing can not only be improved in this way
The intensity of built-in pipe 1, and can be improved the cementability of sealing built-in pipe 1 Yu concrete, make to be bonded it is stronger, while can also
Play good sealing effect.
In order to improve the safety used, fire trapping ring 21 is installed on the outer wall of noise reduction connector 6.Fire can be prevented in this way
When calamity, high fire is burned on floor by noise reduction connector.
In order to guarantee to have always in water seal storage area 3 water, tap water water supply pipe, tap water preferably are connected in drainage layer 11
One end of water supply pipe is connect with running water pipe, and the other end is protruded into water seal storage area 3 and (is not drawn into figure) after passing through drainage layer 11.
When not waste discharge per family is used as oneself user and upstairs in this way, the openable water tap of user, using tap water to water
It seals storage area and carries out moisturizing, since the volume of water seal storage area is smaller, so need to only open water tap 2 seconds or so
Make to guarantee that water seal is worked always full of water in water seal storage area.
In the construction of structural slab main body concrete, sealing built-in pipe 1 is mounted in floor first, then successively installation position transposition section
Inner cover 2, noise reduction connector 6, cyclone 7, fire trapping ring 21, lower drainpipe 10, tee tube, lengthen pipe plug reducing connecting tube 15 and on
The specific mounting means of drainpipe 18, the above structure is the prior art, after above structure is installed, in moisturizing connector 4
The upper self-complementary water pipe 5 of bonding, and protruded into water seal storage area 3 after the lower end of self-complementary water pipe 5 is passed through drainage layer 11, complete installation.
In factory process, moisturizing connector 4 is processed on tee tube, so during installation, is directly glued self-complementary water pipe 5
It connects on moisturizing connector 4, facilitates installation；In fact, existing tee tube can also be used, during installation, first with drilling
Device will drill out through-hole on the outer wall of tee tube, then be bonded special joint pipe on the outer wall, finally again be bonded in self-complementary water pipe 5 specially
With on junction block, existing tee tube, save the cost can be utilized in this way.
A kind of encapsulating method of Three-section water stop casing, Three-section water stop casing are divided into Drainage Section, pre- from top to bottom
It buries section and connects section under, water seal storage area is set in the antipriming pipe of embedded section, in use, if in bathroom, bathing
The waste water flowed on floor afterwards flows into water seal storage area, makes full of waste water in water seal storage area, thus using waste water to three-stage
The rises of sealing casing carries out water seal.
In the positions such as balcony or kitchen, since the waste water on floor is less, in order to guarantee the waste water in water seal storage area
It is not vaporized completely, self-complementary water pipe is set on the tube wall of Drainage Section, upstairs the waste water of user is by passing through self-complementary water pipe to building
Water seal storage area in the embedded section of lower user is automatically replenished, to guarantee that water seal storage area forms always water seal.
In fact, the water seal storage area of embedded section can also connect by tap water water supply pipe with running water pipe, is being used
Tap water carries out moisturizing to water seal storage area.When using not waste discharge per family as oneself user and upstairs in this way, user can be beaten
Water tap is opened, moisturizing is carried out to water seal storage area using tap water, since the volume of water seal storage area is smaller, so only needing
It opens water tap 2 seconds or so, can make to guarantee that water seal is worked always full of water in water seal storage area.
Three-stage self-water replenishing water seal sealing casing provided by the utility model is described in detail above.Specific implementation
The explanation of example is merely used to help understand the method and its core concept of the utility model.It should be pointed out that for the art
Those of ordinary skill for, without departing from the principle of this utility model, can also to the utility model carry out it is several
Improvement and modification, modifications and modifications also fall within the protection scope of the claims of the utility model.
