Description
Technical field
The invention belongs to pressure piping build design field, be specially adapted to the pressure piping that water supply is united in the water power plant, relate to a kind of flat uniform section steel bifurcated pipe.
Background technique
Bifurcated pipe be responsible for each arm between the special special-shaped pipeline section that diverges and be connected.Steel bifurcated pipe on the conduit pipe of existing water power plant generally is arranged in the tube's axis of the person in charge, bifurcated pipe, arm on the same elevation.The build of each pipeline section is symmetry up and down.Have the discrepancy in elevation at the bottom of each pipeline section pipe, when predominant tube diameter was big, the discrepancy in elevation can surpass 2m.The tube's axis of the person in charge, bifurcated pipe, arm is arranged on the same elevation, not enough below existing: 1, construction time, turn(a)round impeded drainage; 2, construction time, turn(a)round, have inconvenient traffic.
Summary of the invention
The purpose of this invention is to provide a kind of new steel bifurcated pipe, promptly a kind of flat uniform section steel bifurcated pipe overcomes the deficiency of existing steel bifurcated pipe, make construction time, turn(a)round draining smooth and easy, have a good transport service.
Technological scheme of the present invention is: a kind of flat uniform section steel bifurcated pipe; It is characterized in that: which comprises at least main leg, oval converging transition, oval section, transition section, bifurcated pipe section, the pipeline section of being connected; Main leg, oval converging transition, oval linking section, transition section, bifurcated pipe section, a pipeline section join successively, and the pipe end keeps level.
Described main leg is a steel bifurcated pipe inducer, selects conventional round pressure steel pipe for use.
Described oval converging transition tapers to ellipse by the main leg is just round, and oval converging transition height is constant, and only width reduces.
Described oval to be connected section suitable for reading be elliptic jet, and its end opening is the interior symmetrical angular cuts of two vertical guides, and otch is two semicircles, just in time joins with half right angle oblique cone face of the transition section left and right sides.
Described transition section height is reduced to the arm diameter by main leg's diameter, and width is widened to by ellipse short shaft is convenient to the width that joins with the bifurcated pipe section, and its end face is the isosceles triangle that has a down dip; Triangle base and bifurcated pipe section end face intersect, and the bottom surface is the triangle in the basal plane, and the projection of end face triangle on basal plane overlaps with the bottom surface triangle; Its left and right sides is half oblique cone face; This oblique cone face is a right angle oblique cone face, and end circle is round for just, and the conical surface summit is on a plain line of the conical surface perpendicular to end circle; The intersection of oblique cone face and bifurcated pipe section is the semicircle in vertical guide, semicircle diameter and arm equal diameters.
Described bifurcated pipe section height and arm equal diameters, the end, top is a disk, is the hemicycle anchor ring on every side, toroidal surface diameter and arm equal diameters.
Described pipeline section is steel bifurcated pipe outlet section, selects conventional round pressure steel pipe for use.
Be arranged as near the uniform section transition from the main leg to the bifurcated pipe section, all adopt steel plate to roll.
The invention has the beneficial effects as follows: 1, flat uniform section steel bifurcated pipe has solved flat and the uniform section problem, construction time, turn(a)round draining and traffic are provided convenience, and the shell build clearly can be made.
2, the bifurcated pipe basal area is no more than person in charge's basal area, can reduce because of section becomes the big loss of head that produces air trapping problem when the bifurcated pipe height can be avoided water-filling less than person in charge's height.
3, the bifurcated pipe height reduces to the arm diameter by being not less than predominant tube diameter, can improve the bifurcated pipe structure.
4. be that unique realizing branches off the bifurcated pipe of ware.

Embodiment
A kind of flat uniform section steel bifurcated pipe; It is characterized in that: which comprises at least main leg 1, oval converging transition 2, oval section 3, transition section 4, bifurcated pipe section 5, the pipeline section 6 of being connected; Main leg 1, oval converging transition 2, oval linking section 3, transition section 4, bifurcated pipe section 5, a pipeline section 6 join successively, and the pipe end keeps level.。
Like Fig. 1, shown in 2, a kind of flat uniform section steel bifurcated pipe comprises main leg 1, oval converging transition 2, oval section 3, transition section 4, bifurcated pipe section 5, the pipeline section 6 of being connected at least, is arranged as near the uniform section transition from main leg 1 to bifurcated pipe section 5, all adopts steel plate to roll.As shown in Figure 1, main leg 1 is a steel bifurcated pipe inducer, is conventional round pressure steel pipe.Oval converging transition 2 tapers to ellipse by main leg 1 is just round, and the elliptical cross section area is slightly less than person in charge's sectional area.The oval section 3 that is connected is for being connected the pipeline section that oval converging transition 2 and transition section 4 are provided with, and it is suitable for reading to be elliptic jet; Its end opening is the symmetrical angular cuts in two vertical guides, and otch is two semicircles, just in time joins with half right angle oblique cone face of the transition section left and right sides.As shown in Figure 2, transition section 4 its effects are to flatten conduit section gradually, and height is reduced to the arm diameter by main leg's diameter, and width is widened to by ellipse short shaft is convenient to the width that joins with the bifurcated pipe section.Its end face is the isosceles triangle that has a down dip, and triangle base and bifurcated pipe section end face intersect, and the bottom surface is the triangle in the basal plane, and the projection of end face triangle on basal plane overlaps with the bottom surface triangle.Its left and right sides is half oblique cone face, and this oblique cone face is a right angle oblique cone face, and end circle is round for just, and the conical surface summit is on a plain line of the conical surface perpendicular to end circle.The intersection of oblique cone face and bifurcated pipe section is the semicircle in vertical guide, semicircle diameter and arm equal diameters.As shown in Figure 3, the similar cake of bifurcated pipe section 5 its builds, height and arm equal diameters; The end, top is a disk, is the hemicycle anchor ring on every side, toroidal surface diameter and arm equal diameters; This build is the similar water turbine volute again; But simpler than spiral case, the spiral case diameter is gradually little, and the bifurcated pipe toroidal surface is an equal diameter.Bifurcated pipe is chosen as the cake build, is for the ease of being connected with arm, and reduces the buttress brace height.Pipeline section 6 be a steel bifurcated pipe outlet section, is conventional round pressure steel pipe, but fork angle Reference Design standard three beam bifurcated pipes and spherical manifold penstock are selected between arm.Can be divided into Liang Cha, three troubles, even four troubles.
