Description

Inspection opening for building drainage

Technical Field

The utility model relates to a building drainage field, in particular to an inspection opening for building drainage.

Background

The residential drainage system comprises a single-vertical-pipe drainage system, a double-vertical-pipe drainage system and a three-vertical-pipe drainage system, and in order to facilitate the pipeline maintenance of the residential drainage system, inspection ports are required to be installed in the drainage system and used for inspecting the drainage condition of the drainage system pipeline and dredging the blockage of a drainage pipeline.

At present, after the cover plate on the inspection opening is opened, sewage and wastewater in the drainage pipeline is splashed outwards at the inspection opening, so that the environmental pollution is caused, and the difficulty is brought to the maintainers. In order to conveniently overhaul the drainage pipeline and prevent sewage and wastewater from splashing outside the inspection opening, an inspection opening is urgently needed to be developed.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides an inspection opening for building drainage can convenient and fast inspection and clearance drainage pipe, prevents that dirty waste water from outwards splashing four times at the inspection opening, reduces environmental pollution.

On the one hand, the utility model provides an inspection socket for building drainage is provided with the inspection pipe of outside extension in one side of drain pipe, has seted up the inspection socket at the outer port of inspection pipe, installs the apron on the inspection socket, and the internal diameter H2 of inspection pipe is greater than inspection socket internal diameter H1, and the outer port outer wall of inspection pipe is greater than 10mm to drain pipe outer wall distance L1.

In a further technical scheme, the inner diameter H3 of an intersection of the inspection pipe and the drain pipe is larger than the inner diameter H2 of the inspection pipe, the central line of the inner diameter H3 of the intersection deviates downwards relative to the central line of the inner diameter H2 of the inspection pipe, and a downward inclined cambered surface is formed at the intersection of the drain pipe and the lower side of the inspection pipe.

In a further technical scheme, the distance L1 from the outer port outer wall of the inspection tube to the outer wall of the drainage tube is greater than 20mm, the inner diameter H3 of the intersection port is greater than 120mm, the inner diameter H2 of the inspection tube (2) is greater than 100mm, and the inner diameter H1 of the inspection port is greater than 50mm.

The utility model discloses an inspection opening for building drainage compares prior art beneficial effect and lies in:

can convenient and fast inspection and clearance drainage channel, prevent that dirty waste water from outwards spattering in inspection opening four times, reduce environmental pollution, the structure is ingenious, and utility model is strong.

Drawings

The accompanying drawings, which form a part of the present disclosure, are included to provide a further understanding of the present disclosure, and are incorporated in and constitute a part of this specification, illustrate embodiments of the present disclosure and together with the description serve to explain the present disclosure. In the drawings:

FIG. 1 is a schematic view of an inspection opening for building drainage according to the present invention;

fig. 2 is a side view of fig. 1.

Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1 and 2, the utility model provides an inspection opening for building drainage is provided with outside extension inspection tube 2 in one side of drain pipe 1, has seted up inspection opening 20 at the outer port of inspection tube 2, installs apron 3 on inspection opening 20, and apron 3 passes through the bolt fastening on the outer port of inspection tube 2, and the sealed check opening 20 that lives of apron 3. The internal diameter H2 of inspection pipe 2 is 100mm, and inspection opening 20 internal diameter H1 is 60mm, and the internal diameter H2 of inspection pipe 2 is greater than inspection opening 20 internal diameter H1, and the outer port outer wall of inspection pipe 2 is 40mm to drain pipe 1 outer wall distance L1.

In order to further prevent dirty waste water and outwards splash at the inspection opening, reduce environmental pollution, inspection pipe 2 is 130mm with the mouth internal diameter H3 that intersects of drain pipe 1, and inspection pipe 2 is greater than the internal diameter H2 of inspection pipe (2) with the mouth internal diameter H3 that intersects of drain pipe 1, and the relative internal diameter H2 central line of inspection pipe 2 of mouth internal diameter H3 central line that intersects squints downwards, and drain pipe 1 forms downward sloping cambered surface 21 with the 2 downside junctions of inspection pipe. When dirty waste water in drain pipe 1 flows down along the inside pipe wall, dirty waste water can splash to slope cambered surface 21 on, because inspection tube 2 outwards extends and has the certain distance, inspection socket 20 internal diameter H1 is less than inspection tube 2's internal diameter H2 moreover, drain pipe 1 forms downward sloping cambered surface 21 with inspection tube 2 downside intersection, dirty waste water in drain pipe 1 is blockked in drain pipe 1, can not follow inspection socket 20 outwards to spatter all around, reduce environmental pollution, convenient and fast inspection and clearance drainage channel.

The techniques not described above are common general knowledge of the person skilled in the art. The above description is only for the preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
