Problems solved by technology

[0003] 1. Drilling on the spherical head: the contact between the miter pipe 3 and the head 2 is a spherical slope, and the drill bit cannot be positioned directly on the spherical slope;
[0004] 2. Processing after fitting the groove of the pipe joint with the spherical surface: because the head 2 is pressed with a steel plate, there is a certain difference between the drop at the groove of the mitered pipe 3 and the size of the drawing, and the points A and B on the outer wall of the hole on the head are calculated according to theory. The drop is 8mm, and it is difficult to match the groove of the pipe joint with the spherical surface;

Embodiment

[0023] Such as figure 1 , 2 Figure 3 is a schematic diagram of the spherical distributor structure. This embodiment further illustrates the present invention by manufacturing 16 spherical distributors in a 350MW tower gas and oil-fired boiler of Baosteel 4# unit.

[0024] A manufacturing process of a spherical distributor is:

[0025] The first step. Install the pipe joint 4 and the inner long tube 6 inside and outside the top of the upper half of the head 1 with a diameter of 508mm, so that the pipe joint 4 and the inner long pipe 6 are located on the diameter of the upper half of the head 1. 4 The diameter of the inner long pipe 6 is the same, the diameter is 100mm, the pipe joint 4 is 148mm long, and the inner long pipe 6 is 248mm long;

[0026] Step 2. Draw 26 positions to be punched evenly in a circle at the center line of the miter pipe 3 pipe hole 60mm away from the ring seam of the lower part of the head 2 and on each lower part of the head to be drilled The highest point A ...

Abstract

The invention relates to a technique for producing a spherical distributor, the technique is characterized in that a pipe joint and an inner long pipe are respectively arranged inside and outside the top part of an end enclosure in the upper half part; planes are grinded at each A-B position needed to be drilled for drilling and locating; the fall size of A point and B point is obtained by measuring and is used as the fall size for processing the incline at the position of the orifice of an inclined jointing pipe; then the inclined jointing pipe is processed; a tapered pipe is arranged at thebottom part of an end enclosure in the lower half part; then an inner short pipe is arranged in the bottom part of the end enclosure in the lower half part to lead the tapered pipe, the inner short pipe, the pipe joint and the inner long pipe to be arranged on the same line; moreover, an inner piece is welded in the end enclosure of the lower half part; the tapered pipe is respectively welded with each hole in a circle in the end enclosure of the lower half part; finally the end enclosure of the upper half part and the end enclosure of the lower half part are jointed; an automatic-welding circular seam is employed between the end enclosure of the upper half part and the end enclosure of the lower half part. The technique for producing the spherical distributor has the advantages of solving the problem of localization and saving the producing cost.

Description

Technical field [0001] The invention relates to a manufacturing process of a spherical distributor, in particular to a manufacturing process of a spherical distributor of a boiler water cooling system, and belongs to the technical field of manufacturing processes of a spherical distributor. Background technique [0002] At present, for the spherical distributor, only three boilers manufactured by the German Babuque Company have been applied. The domestic boiler industry manufacturers have not manufactured the same type of distributor. However, the applicant is concerned about the German Babuque company's manufacturing of spherical distributors. Know nothing about the process, to manufacture the spherical distributor, the drilling on the spherical head, the processing after the groove of the pipe joint is matched with the spherical surface, the establishment of the installation sequence to prevent the garbage from falling, the pipe joint after the hydraulic test of the distributor ...
