Description
Technical field
Buildings waterproof field is the utility model is related to, is related to the water string of architecture indoor pipeline, more particularly, to one kind
New waterproof sleeve pipe.
Background technology
At present, in construction, mainly interior plumbing system is built using following two modes.The first is pipeline
Place needs to hang mould by the way of reserved opening, after concreting carrys out fixed -piping；The indoor row built in this way
It is not firm that water system is fixed, and easy leak.It is for second by the way of pre-embedded water-proof sleeve tube, but water string is interior
Footpath is more than outer diameter tube, and the space of water string and pipeline needs the later stage to block, due to not being between pipeline and water string
It is definitely fixed, gap is easily formed at closure, so as to drainage occur.
The content of the invention
In order to solve above-mentioned problem, the utility model proposes a kind of new waterproof sleeve pipe, the water string can
Solve the seepy question that gap by pipeline and sleeve pipe being present and occurring, can also solve the seepy question of sleeve pipe and floor contact surface.
To achieve these goals, the utility model uses following scheme, including：Upper sleeve pipe, intervalve, setting of casing, Gu
Determine ring, the first seal ring, ring-shaped step, the second seal ring, inner tube and spacing hole；
The intervalve is in shaped hollow round table；The intervalve upper end extends to form the upper sleeve pipe straight up, described
The lower end outer wall of upper sleeve pipe is provided with the first seal ring；The intervalve lower end is horizontal-extending to form the ring-shaped step；The ring
The inner ring of shape step extends to form said inner tube straight down；The outer ring of the ring-shaped step extend straight down to be formed it is described under
Sleeve pipe, the cased outer wall are provided with second seal ring；The horizontal-extending formation in cased lower end is described solid
Determine ring, some spacing holes are circumferentially uniformly provided with the retainer ring.
Further, the length of said inner tube is less than the cased length.
Further, the number of the spacing hole is 4.
Further, the diameter of the intervalve upper end is more than the diameter of lower end.
Further, the thickness for the annular space that the setting of casing is formed with said inner tube is more than the thickness of tube wall.
As further improvement of the utility model, the seal ring is upwardly formed annular protrusion along outer ring.
The design of intervalve of the present utility model can allow pipeline location to fix, while beneficial to the flowing of water；Due to down tube
Road upper end is embedded in the annular space that the setting of casing is formed with said inner tube, and water directly can enter inner tube by intervalve, enter back into
Lower pipeline, water is avoided to enter lower pipeline and cased gap；Because the upper sleeve pipe and cased outer wall are provided with seal ring,
Effectively water is prevented from sleeve pipe and floor contact surface seepage；Projection on seal ring is advantageous to prevent the seepage of water.
Brief description of the drawings
Fig. 1 is the schematic cross-sectional view of the utility model water string.
Fig. 2 is the installation schematic cross-sectional view of the utility model water string.
In figure：Sleeve pipe on 1.；2. intervalve；3. setting of casing；4. retainer ring；5. the first seal ring；6. ring-shaped step；7. the
Two seal rings；8. inner tube；9. spacing hole；Pipeline on 10.；11. lower pipeline；12. floor；13. fixed form.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, so that those skilled in the art can be more
Add and be apparent from.
As shown in figure 1, the utility model uses following scheme, including：Upper sleeve pipe 1, intervalve 2, setting of casing 3, retainer ring
4, the first seal ring 5, ring-shaped step 6, the second seal ring 7, inner tube 8 and spacing hole 9；The intervalve 2 is in shaped hollow round table；Institute
State the upper end of intervalve 2 to extend to form the upper sleeve pipe 1 straight up, the lower end outer wall of the upper sleeve pipe 1 is provided with the first seal ring
5；The lower end of intervalve 2 is horizontal-extending to form the ring-shaped step 6；The inner ring of the ring-shaped step 6 extends shape straight down
Into said inner tube 8；The outer ring of the ring-shaped step 6 extends to form the setting of casing 3 straight down, the outer wall of the setting of casing 3
It is provided with second seal ring 7；The lower end of the setting of casing 3 is horizontal-extending to form the retainer ring 4, in the retainer ring 4
Circumferentially it is uniformly provided with some spacing holes 9.The length of said inner tube 8 is less than the length of the setting of casing 3.The spacing hole 9
Number is 4.The diameter of the upper end of intervalve 2 is more than the diameter of lower end.The ring that the setting of casing 3 is formed with said inner tube 8
The thickness in shape space is more than the thickness of tube wall.The seal ring is upwardly formed annular protrusion along outer ring.
As shown in Fig. 2 water string is fixed on fixed form 13 with screw, cast concrete forms floor 12；Pipe
When road is installed, upper pipeline 10 is inserted in upper sleeve pipe 1, the lower upper end of pipeline 11 is embedded in into the setting of casing 3 forms with said inner tube 8
Annular space in.
The design of intervalve of the present utility model can allow pipeline location to fix, while beneficial to the flowing of water；Due to down tube
Road upper end is embedded in the annular space that the setting of casing is formed with said inner tube, and water directly can enter inner tube by intervalve, enter back into
Lower pipeline, water is avoided to enter lower pipeline and cased gap；Because the upper sleeve pipe and cased outer wall are provided with seal ring,
Effectively water is prevented from sleeve pipe and floor contact surface seepage；Projection on seal ring is advantageous to prevent the seepage of water.
