Abstract

The utility model provides a special lateral arc-shaped shrank inward pipe piece for public ventilating and exhausting facilities of buildings, which comprises a main pipe (1) and a lateral arc-shaped pipe (2), wherein, the diameter of the arc-shaped pipe is gradually shrank, and the arc-shaped pipe is inwards protruded in the wall of the main pipe to form a step. The integral pipe piece can be formed by casting and can also be formed by injection moulding. The special lateral arc-shaped shrank inward pipe piece is designed according to the property and the flowing rule of air and is used for exhausting indoor foul air, and the utility model can accelerate indoor air exchange of the buildings and ensure the people's body health. The utility model has the advantages of simple and practical structure, bulk production, processing and formation, convenient construction and installation and low cost, improves the air quality of the people's inhabited environment and cleans the appearance of the walls of urban building groups.

Description

Side arc convergent convex pipe fitting

The utility model relates to a kind of pipe fitting, relates in particular to a kind of side arc convergent convex pipe fitting that is exclusively used in the public use that builds a building.

The city high-rise building takes up an area of few, and resident family concentrates, and living floor space enlarges year by year, and people's life housing condition improves.The builder is in order to reduce the cost cost, and house type is concentrated design, also brings living space gas exchange not smooth simultaneously, especially adjacent resident family, levels resident family, dirty gas peculiar smell is gone here and there mutually between the chamber, influences quality of life, need to increase corresponding communal facility, according to the character and the flowing law of gas, manufacture side arc convergent convex pipe fitting, utilize natural conditions, can accelerate the gas exchange, ensure that people are healthy.

The purpose of this utility model provides the special pipe fitting of a kind of form of structure, and common the use utilized the natural law, accelerates the side arc convergent convex pipe fitting that improves people's living environment of interchange of air.

The technical solution of the utility model is achieved in that

Be exclusively used in the side arc convergent convex pipe fitting of building indoor and outdoor: comprise main pipe (1), side curved pipe (2), the segmental arc diameter is diminishing, and protruding entering in the trunk tube wall is made into a step, and this pipe fitting is an integral body.Can cast form, but also injection molded.

Figure is a side arc convergent convex pipe fitting sectional view, and arrow line is a gas flow direction.

Pipe fitting is responsible for a mouthful connection straight tube and is connected successively from top to bottom by layer, is fixed on the construction wall of building indoor and outdoor, can form the chimney (or claiming stack) that height is holded up.The side arc convergent convex mouth of pipe introduce adjacent in every family between, between the levels or between the indoor room, utilize the natural draft of chimney, the indoor dirty gas in family can be discharged outdoorly, accelerate the gas exchange, improve IAQ (indoor air quality).

Good effect of the present utility model is:

1, accelerates interchange of air naturally, improve the indoor gas quality.

2, emission gases is connected on the public pipeline, can containment of fluid flow path warp, reduce the foul smell string adjacent resident family of influence that looses.

3, kitchen row smoke extractor is connected on the pipeline, not influenced by four corners of the world wind direction and carries out exhaust.The oil stain that discharge in the kitchen converges on the public pipeline, can solve the operation room emission gases pipe that generally uses and stretch out outdoor grunge pollution building wall, clean urban architecture building skirt.

4, gas utilizes power-equipment to discharge in pipeline in the building room, and the exchange effect is better.

Technical characterictic of the present utility model and effect:

The communal facility crux problem that solves interchange of air in the urban building is the pipe fitting interface.The side camber convergent convex pipe fitting trunk mouth of pipe can be gone up lower link.The side mouth of pipe can be one or more, and sweep makes all directions air-flow enter the person in charge and do not liquidate mutually, and use is independent of each other.The segmental arc tapered diameter partly makes bending section flow velocity increasing minimizing foul smell sediment adhere to.There is a step interior convex edge and trunk tube wall junction, are responsible for the square straight down material that falls down, flows down and are difficult for entering in the side pipe, guarantee that pipeline is unobstructed, realize the interchange of air purpose.

Side arc convergent convex fitting structure is simple and practical, can make shaping in batches, and convenient construction is installed, and the cost cost is low, improves the air quality of people's dwelling environment, clean urban building skirt and wall appearance.

Claims

1, a kind of side arc convergent convex pipe fitting that is exclusively used in building constructions is characterized in that: comprise main pipe (1), side arc convergent convex pipe (2), be whole pipe fitting on.

2, the side arc convergent convex pipe fitting feature that is exclusively used in building constructions according to claim 1 is: the side pipe is an arc, and diameter dwindles gradually, protrudingly advances in the main pipe, makes a step.
