Abstract
The utility model relates to an elbow joint, belonging to the technical field of pipes, and aiming to overcome the defects of the traditional arc elbow joints and reduce loss of airflow at a corner airflow press head and air quantity. The elbow joint comprises two pipes and is characterized in that elbow joints at corners of the pipes are cylindrical pipe and the cylindrical pipes and the two pipes are connected by certain included angles. Through the scheme of the utility model, the elbow joint is of a simple structure and is practical so as to reduce the loss of air pressure and flow rate.
Description
Technical field
A kind of elbow metal conduit technical field, the bend pipe that is suitable for supply air duct especially connects.
Background technique
Elbow between the existing pipeline all is to adopt curve bend, because that air-flow can be turned back in the arc position is inconsistent with original air-flow, reduces the pressure of former air-flow; Again because the radian of each position of curve bend is inequality; The angle that air-flow turns back is also inequality, therefore, forms the air-flow of turbulent mode at elbow; So the loss of pressure head of curve bend joint air-flow is very big, has also significantly reduced gas pushing quantity.
Summary of the invention
A kind of elbow that the utility model proposes its objective is the shortcoming that overcomes existing curve bend joint, reduces air-flow in the loss of air-flow pressure head and air quantity of turning round out.
A kind of elbow comprises pipeline, and the elbow that it is characterized in that the pipeline corner is a cylindrical duct, becomes certain included angle to be connected between cylindrical duct and two pipelines.
Above-mentioned a kind of elbow is characterized in that the angle between described cylindrical duct and two pipelines is 132-135 degree.
The scenario-frame of the utility model is simple, practical, has reduced the loss of air pressure and flow.
Description of drawings
Fig. 1 is a kind of structural representation of elbow.
Embodiment
With specific embodiment explanation, Fig. 1 has shown a kind of structure of elbow at present, and it is made up of pipeline 1, pipeline 3 and cylindrical duct joint 2.Cylindrical duct joint 2 is the 132-135 degree with the angle that pipeline 1 is connected with pipeline 3.
Claims (2)
1. an elbow comprises pipeline, and the elbow that it is characterized in that the pipeline corner is a cylindrical duct, becomes certain included angle to be connected between cylindrical duct and two pipelines.
2. a kind of elbow according to claim 1 is characterized in that the angle between described cylindrical duct and two pipelines does
132-135 degree.
