Description

Blow-off pipe with oval tube body

Technical field

The utility model belongs to blow-off pipe technical field, is related to a kind of blow-off pipe with oval tube body.

Background technology

Concealed water tank is fixed on vacation within the walls by rack, installs blow-off pipe thereon and is used to carry out blowdown to closestool.It is existing Blow-off pipe be all round tube, blow-off pipe is between rack and wall, insufficient since the gap between rack and wall is smaller To accommodate blow-off pipe, so needing to dig wall when installing blow-off pipe for blow-off pipe insertion, due to being relatively large in diameter for round tube, chisel Wall depth is deeper, and construction intensity is big, and larger to wall damage, and making wall, there are larger security risks.

Invention content

In view of the problems of the existing technology the utility model proposes a kind of blow-off pipe with oval tube body, it is therefore intended that Overcome and the defects of round blow-off pipe needs chisel wall deeper is installed in the prior art, reduce construction intensity, reduce installation blow-off pipe pair The destruction of wall.

The utility model is realized in this way：

Blow-off pipe with oval tube body, which is characterized in that including with round dirt inlet into dirty section, with elliptical tube Main paragraph and linkage section with round connector, the both ends of the main paragraph connect respectively with described into dirty section and linkage section It is logical.

After blow-off pipe installation, the short axle of the elliptical tube on main paragraph is horizontally disposed with, and since elliptical tube is more flat, is ensureing blowdown Under the premise of ability, transverse width can be reduced, the depth relative to wall embedded required for round tube is smaller, digs wall depth minus Small, construction intensity reduces, and the destruction of wall is reduced, wall is made not allow to be also easy to produce security risk.

Preferably, the main paragraph includes embedded division, transition part and relief portion, and the embedded division is elliptical tube, described embedding Enter portion to connect into dirty section with described, the relief portion is connected with the linkage section, and the intermediate location is in the embedded division and keeps away It allows between portion, the embedded division and the relief portion shift to install.Embedded division only need to be embedded in wall in this way, and relief portion need not Embedded wall reduces main paragraph length of embedded wall required for being embedded in, and chisel wall length reduces, further to the destruction of wall Reduce.

Preferably, the transition part and relief portion are all elliptical tubes.Make transition part in this way and relief portion is easier avoids Wall reduces the dislocation distance of embedded division and relief portion, reduces the adverse effect because misplacing to blowdown fluency.

Preferably, described vertical into dirty section and the embedded division, the side offset of the relief portion toward dirt inlet direction is set It puts.It can adapt to the setting of normal framework in this way.

Preferably, the blow-off pipe is integrally moulded part.Blow-off pipe is easy to process in this way and is less likely to occur to leak.

Preferably, it is described to be connected into rounding off between dirty section and the embedded division, the relief portion and the linkage section Rounding off connects.The fluency of blow-off pipe blowdown is advantageously ensured that in this way.

Preferably, the embedded division tilts down.Being conducive to linkage section in this way can be with ground against not having to linkage section Additional support member is supported on wall, can also reduce the destruction to wall in this way.

Preferably, it is described into having an annular groove in dirty section.Blow-off pipe is fixed by the anchor ear being embedded in annular groove In rack, be conducive to the fixed stability of blow-off pipe.

Preferably, the junction between the relief portion and the linkage section tilts down from relief portion to linkage section.This Sample sewage would not be deposited in junction, make blowdown thorough.

Preferably, the long axis of the elliptical tube and short axle ratio are 10:6-10:8.Axial ratio is too big, and elliptical tube is excessively flat, circle The connection of pipe and elliptical tube is unfavorable for the fluency of blowdown, and axial ratio is too small, is unfavorable for reducing chisel wall depth.

The blow-off pipe with oval tube body provided by the utility model, since its main paragraph has elliptical tube, and it is oval The short axle of pipe is smaller, that is, elliptical tube is more flat, reduces blow-off pipe insertion wall in the case where ensureing that pollution discharge capability is constant in this way The depth of body reduces chisel wall depth, reduces the destruction to wall.

Specific embodiment

Just attached drawing in conjunction with the embodiments below, is described in further detail specific embodiment of the present utility model, so that this Utility model technical solution is more readily understood, grasps.It should be appreciated that specific embodiment described herein is only explaining this reality With novel, it is not used to limit the utility model.

A kind of blow-off pipe with oval tube body is present embodiments provided, main and concealed formula water tank is used cooperatively, In the rack 400 of concealed water tank.As shown in Figs. 1-5, blow-off pipe is the forming of PE integrally blows, including into dirty section 100th, main paragraph 200 and linkage section 300, wherein main paragraph 200 are again including embedded division 210, transition part 220 and relief portion 230.Row Dirty pipe, which passes through, to be followed successively by into dirty section 100, embedded division 210, transition part 220, relief portion 230, linkage section 300.

Into dirty section 100 there is circular dirt inlet to be connect by other blow-off pipes with closestool, consolidated into dirty section 100 by anchor ear Be scheduled in rack 400, into dirty section 100 on have annular groove 110, annular groove 110 can be on tube wall setting bulge loop shape Into can also be directly recessed by tube wall, since tube wall is relatively thin, tube wall indent easily makes inside pipe wall out-of-flatness, so this reality Example is applied to use in pipe outer wall setting bulge loop formation annular groove 110.Anchor ear makes to fix into dirty section 100 in annular groove 110 Securely.

Into dirty section 100 and 210 relative angle of embedded division depending on actual conditions, under normal circumstances, into dirty section 100 and embedding It is vertical to enter portion 210, that is, into the central axis of dirty section 100 and the central axis upright of embedded division 210.It is round and smooth into dirty section 100 Embedded division 210 is transitioned into, embedded division 210 is elliptical tube, and under normal circumstances, embedded division 210 needs to be embedded into wall, embedding The minor axis for entering portion 210 is horizontally disposed with.Long axis and the short axle ratio of elliptical tube are 10:6-10:8, preferably 10:7, such as long axis is 100 millimeters, short axle is 70 millimeters.

Refering to Fig. 5, to relief portion 230 toward wall outer incline, such relief portion 230 passes through in transition part 220 self-embedding portion 210 After transition part 220 and embedded division 210 connect, embedded division 210 and relief portion 230 shift to install, i.e. relief portion 230 is toward dirt inlet court To side deviate, about 60 millimeters of offset distance.Embedded division 210 and transition part 220 all tilt down, and enable linkage section 300 It is resisted against ground.Transition part 220 is in bending arc shape, and consistent with the major and minor axis of embedded division 210.

Relief portion 230 can be that pipe can also be elliptical tube, and the present embodiment uses elliptical tube, relief portion 230 and insertion After portion 210 misplaces, it may not be necessary to embedded wall.230 rounding off of relief portion is to linkage section 300, and the two junction is by relief portion 230 It is tilted down to linkage section 300.The connector of linkage section 300 is circle, and linkage section 300 is used for and other round blow-off pipes connect It connects.
