Description

Large-flow bridge-crossing four-way pipe fitting

[ technical field ] A method for producing a semiconductor device

The utility model relates to a technical field of building feed pipe, especially a technical field of large-traffic cross bridge tee bend pipe fitting.

[ background of the invention ]

In traditional decoration, indoor feed pipe gets into from outdoor water gauge, for pleasing to the eye, all adopts the concealed installation, and different regions, hydraulic installation custom are different, and when the decoration of part region, bury the pipeline in the underground secretly, because the pipeline is very complicated, need alternately lay partly pipeline in the installation unavoidably. In traditional construction, a crescent special bridge span bend is adopted to span another pipe, or four-way pipe fittings which are not communicated with each other are adopted. There are two problems in the curved existence of traditional crescent moon type gap bridge: firstly, the inner channels of the product are not on the same straight line, namely the projection of the section of the middle channel part exceeds the area range of the interfaces at two ends, so that the core-pulling mechanism of the die is complex and the manufacturing cost is high; and secondly, the traditional crescent gap bridge is bent, and due to the adoption of a split structure, the gap bridge is required to be bent and cross the pipeline in a crossing manner, the total height of the overlapped part occupies space, the ground filling layer is required to be increased by 6-10 mm in thickness, the construction cost is increased, and the height space of a building layer is also influenced. For the four-way pipe fitting, the space in the pipeline crossing position is generally equally divided and separated by the internal partition wall, so that the liquid flow cross section of the two pipelines at the crossing position is only half of that of the normal pipeline, the flow is reduced, the pressure is increased, and the liquid conveying is influenced.

[ Utility model ] content

The utility model aims at solving the problem in the prior art, providing a large-traffic bridge four-way pipe fitting, can reduce the total height of product cross position department when satisfying the liquid transportation demand.

In order to achieve the above object, the utility model provides a large-traffic bridge crossing four-way pipe fitting, including the first pipeline and the second pipeline that intercrossing nevertheless does not communicate each other, first pipeline includes first bridge segment and is located first left interface section and the first right interface section at first bridge segment both ends, the second pipeline includes the second bridge segment and is located the second left interface section and the second right interface section at second bridge segment both ends, first bridge segment part sinks just within the second bridge segment is crossed to the second one side pipe wall that first bridge segment was kept away from to the second bridge segment is outside protruding.

Preferably, the axes of the first and second conduits are offset in height space.

Preferably, the first left interface section and the first right interface section are equal in diameter, and the second left interface section and the second right interface section are equal in diameter.

Preferably, the outer surfaces of the first left interface section and the first right interface section are respectively provided with a plurality of first left bulges and first right bulges which are parallel to the length direction, and the outer surfaces of the second left interface section and the second right interface section are respectively provided with a plurality of second left bulges and second right bulges which are parallel to the length direction.

The utility model has the advantages that: the utility model discloses an integral type design has set up the four-way pipe fitting that has two intersection and mutual noninterference pipeline, through making the second pipeline outwards protrusion, has both increased the liquid circulation cross-section of first gap bridge section and second gap bridge section and can reduce pipeline cross section's total height again to when pipeline is laid along ground, make the filling layer thickness reduce 6 ~ 10mm, practice thrift construction cost, increase floor height usage space.

[ detailed description ] embodiments

Referring to fig. 1, fig. 2 and fig. 3, the utility model relates to a large-traffic bridge four-way pipe fitting, including intercrossing but the first pipeline 1 and the second pipeline 2 that do not communicate each other, first pipeline 1 includes first bridge section 13 and is located first left interface section 11 and first right interface section 12 at first bridge section 13 both ends, second pipeline 2 includes second bridge section 23 and is located second left interface section 21 and second right interface section 22 at second bridge section 23 both ends, first bridge section 13 part sinks in second bridge section 23 and second bridge section 23 one side pipe wall that first bridge section 13 was kept away from to second bridge section 23 outwards bulges, the axis of first pipeline 1 and second pipeline 2 staggers at the high space, first left interface section 11 and first right interface section 12 diameter equal, second left interface section 21 and second right interface section 22 diameter equal, first left interface section 11 and first right interface section 12 are equipped with a plurality of parallel length direction respectively and first right interface section surface 12 are equipped with length direction The outer surfaces of the second left interface section 21 and the second right interface section 22 are respectively provided with a plurality of second left protrusions 211 and second right protrusions 221 which are parallel to the length direction.

The utility model discloses the working process:

the utility model relates to a large-traffic bridge four-way pipe fitting that passes through is in the course of the work, and liquid flows through first pipeline 1 and the second pipeline 2 that each other does not communicate respectively, and first pipeline 1 and 2 intercrossing of second pipeline form certain angle, but first pipeline 1 and second pipeline 2 mutually perpendicular perhaps are similar perpendicular.
