Description
Technical field
The utility model relates to pipe fitting technical field, particularly a kind of three-port structure of gas exhaust piping.
Background technique
Tee pipe fitting is as a kind of connected element of pipeline shunt, and it is widely used in carrying in the pipe network of gas.The tee pipe fitting had in the market installs profile can be divided into Y shape and T-shaped, wherein T-shaped is threeway the most common, straight-through part is identical with the internal diameter that side leads to part, and the axle center that the straight-through part of this T-shaped threeway and side lead to part is intersected at grade, at air-flow, intersection easily causes turbulence, causes port generation explosion, leaks, thus reduce the conveying capacity of pipeline, affect the normal conveying of pipeline.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of three-port structure of gas exhaust piping, and this structure is simple, can avoid turbulence, ensures the normal conveying of pipeline.
The technical solution of the utility model is:
. a kind of three-port structure of gas exhaust piping, comprise downstream steam outlet pipe and two upstream inlet pipes, it is characterized in that: also comprise the pipe that crosses, the upper end of the described pipe that crosses is provided with an air outlet hole, the cross both sides of pipe are respectively equipped with a symmetrically arranged inlet hole, angle between the inlet hole of the described pipe both sides that cross is 60 °, the inlet end of described downstream steam outlet pipe is connected with the air outlet hole of the pipe that crosses, described two upstream inlet pipes are vertically arranged, the outlet side of two upstream inlet pipes is connected respectively by the inlet hole of the connecting tube be obliquely installed with the pipe both sides that cross, the center line of two upstream inlet pipes respectively with line parallel in the steam outlet pipe of downstream, the internal diameter of downstream steam outlet pipe is greater than the internal diameter of two upstream inlet pipes respectively.
The outlet side of downstream steam outlet pipe is provided with the first adpting flange, and the inlet end of described two upstream inlet pipes is respectively equipped with the second adpting flange.
Angle between described each upstream inlet pipe and connecting tube is 120 °.
The outlet side of described each upstream inlet pipe is the angled end-face of 30 °.
The beneficial effects of the utility model: the utility model structure is simple, two upstream inlet pipes are all crossed connecting tube and are connected with the inlet hole of the pipe that crosses, downstream steam outlet pipe is connected with the air outlet hole of the pipe that crosses, angle between the inlet hole of the described pipe both sides that cross is 60 °, downstream steam outlet pipe and two upstream inlet pipes are vertically arranged, the internal diameter of downstream steam outlet pipe is greater than the internal diameter of two upstream inlet pipes respectively, the air-flow of two upstream inlet pipes effectively collects in the downstream steam outlet pipe in a large footpath by this structure, avoid the intersecting line that tube and tube connects, manufacturing process is simple, it is 60 ° by the angle between the inlet hole of the pipe both sides that cross, ensure that the circulate of air-flow, avoid air-flow turbulent flow in three-way pipe.
Two upstream inlet pipes are provided with the second adpting flange, and downstream steam outlet pipe is provided with the first adpting flange, and this adpting flange is convenient to threeway and is connected with the pipeline that crosses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 be in Fig. 1 A to schematic diagram;
Fig. 3 is the B-B sectional view in Fig. 1.
In accompanying drawing, 1 is downstream steam outlet pipe, and 2 is upstream inlet pipe, and 3 is the pipe that crosses, and 3-1 is air outlet hole, and 3-2 is inlet hole, and 4 is connecting tube, and 5 is the first adpting flange, and 6 is the second adpting flange.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
See shown in Fig. 1 to Fig. 3, a kind of three-port structure of gas exhaust piping, comprise downstream steam outlet pipe 1, two upstream inlet pipes 2 and the pipe 3 that crosses, the internal diameter of downstream steam outlet pipe 1 is greater than the internal diameter of two upstream inlet pipes 2 respectively, the internal diameter of the present embodiment downstream steam outlet pipe 1 is 450mm, the internal diameter of two upstream inlet pipes 2 is respectively 342mm, the described upper end crossing pipe 3 is provided with an air outlet hole 3-1, the cross both sides of pipe are respectively equipped with a symmetrically arranged inlet hole 3-2, angle between the inlet hole 3-2 of described pipe 3 both sides that cross is 60 °, the aperture of described air outlet hole 3-1 is greater than the aperture of two inlet hole 3-2 respectively, described downstream steam outlet pipe 1 is vertically arranged, the inlet end of downstream steam outlet pipe 1 is connected with the air outlet hole 3-1 of the pipe 3 that crosses, described two upstream inlet pipes 2 are vertically arranged, the outlet side of two upstream inlet pipes 2 is connected respectively by the inlet hole 3-2 of the connecting tube 4 be obliquely installed with pipe 3 both sides that cross, angle between each upstream inlet pipe 2 and connecting tube 4 is 120 °, the outlet side of described each upstream inlet pipe is the angled end-face of 30 °, the center line of two upstream inlet pipes 2 respectively with line parallel in downstream steam outlet pipe 1.The outlet side of downstream steam outlet pipe 1 is provided with the first adpting flange 5, and the inlet end of described two upstream inlet pipes 2 is respectively equipped with the second adpting flange 6.
Working principle of the present utility model:
Air-flow in two upstream inlet pipes 2 enters respectively by connecting tube 4 and crosses in pipe 3, because the angle between the two inlet hole 3-2 that cross in pipe 3 is 60 °, and the aperture of air outlet hole 3-1 is greater than the aperture of two inlet hole 3-2 respectively, ensure that the air-flow of two upstream inlet pipes 2 turbulent situation does not occur entering in downstream steam outlet pipe 1, avoid threeway explosion, ensure that the normal operation of pipeline.
