Abstract
The invention relates to a flange, in particular to a variable-speed flange, and belongs to the technical field of flange equipment design. The variable-speed flange comprises a flange body, wherein a through hole for allowing materials to pass through is formed in the flange body. The variable-speed flange is characterized in that one end of the through hole is provided with a tapered variable-speed hole, wherein the inner surface of the variable-speed hole is a wavy rough surface; and the hole diameter of the variable-speed hole is smaller than that of the through hole. The diameter of the through hole is 1-4 times that of the variable-speed hole. The variable-speed flange is reasonable and simple in structure, and is easy to produce and manufacture. According to the variable-speed flange, one end of the through hole is provided with the tapered variable-speed hole, the inner surface of the variable-speed hole is the wavy rough surface, and the hole diameter of the variable-speed hole is smaller than that of the through hole. In specific use, materials flows into another pipeline from the through hole through the variable-speed hole, and the hole diameter of the variable-speed hole is smaller than that of the through hole, so that the capacity of the materials which flow into the another pipeline through the variable-speed hole can be reduced relative to the flow rate at the through hole; and the inner surface of the variable-speed hole is the wavy rough surface, and therefore, the material flow at the other pipeline is reduced.
Description
Technical field
The present invention relates to a kind of flange, specifically a kind of speed changing flange, belong to flange equipment de-sign technical field.
Background technique
Flange is again flange plate or bead, flange be make pipe and pipe and and the interconnective part of valve, be connected to pipe end.Flange is paired use generally, and pipeline, by arranging mutually corresponding mounting hole, is well connected through mounting hole by links such as bolts by a pair flange.Existing flange only plays a part connecting tube, cannot control the flow velocity of the material in pipeline.
Summary of the invention
The object of the invention is to solve the problem, a kind of simple and reasonable, speed changing flange of manufacturing easily, can controlling material flow in pipeline is provided.
The object of the invention is to be achieved through the following technical solutions: a kind of speed changing flange, comprise flange body, flange body is provided with the through hole that material passes through, and it is characterized in that, described through hole one end is provided with the speed change hole of taper, and speed change internal surface of hole is corrugated roughened surface; The aperture in described speed change hole is less than the aperture of through hole.
The diameter of described through hole is 1-4 times of speed change bore dia.
Described through hole and speed change hole are welded to connect.
The present invention is rational in infrastructure simply, the manufacturing is easy, and by the present invention, be provided with the speed change hole of taper in through hole one end, speed change internal surface of hole is corrugated roughened surface, and the aperture in speed change hole is less than the aperture of through hole.When concrete use, material flows into another pipeline from through hole through speed change hole, the aperture in speed change hole is less than through hole, relative to the flow velocity of through hole, because the capacity that can flow into another pipeline by speed change hole just diminishes, and speed change internal surface of hole is corrugated roughened surface, therefore just reduces at the mass flow at another pipeline place.
Further, the diameter that the present invention is preferably through hole be the 1-4 of speed change bore dia doubly, through hole and speed change hole are welded to connect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1 flange body, 2 through holes, 3 speed change holes.
