Technique for producing spherical distributor

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 the bottom 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 spherical distributor manufacturing technology. Background technique [0002] At present, the spherical distributor is only used in the three boilers manufactured by the German Babuck company. The domestic boiler industry manufacturers have not manufactured the same type of distributor. I don’t know anything about the technology of the spherical distributor, the drilling of the spherical head, the processing of the pipe joint bevel and the spherical surface, the establishment of the installation sequence to prevent garbage from falling, and the pipe joint after the water pressure test of the distributor. Removal of margin is a key issue to be solved in manufacturing. The existing problems are, such as figure 1 Shown: [0003] 1. Drilling...

AI Technical Summary

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;
