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

A kind of spherical distributor manufacturing process

Technical field

The present invention relates to a kind of spherical distributor manufacturing process, relate in particular to the manufacturing process of the spherical distributor of a kind of boiler water-cooling system, belong to spherical distributor manufacturing process technology field.

Background technology

At present, use to some extent in three boilers that have only German Ba Buke company to make for spherical distributor, each producer of domestic boiler industry did not make distributor of the same type, and the applicant knows nothing for the technology that German Ba Buke company makes spherical distributor, make spherical distributor, boring on the dome head, pipe joint groove and the processing after sphere cooperates, the establishment of order is installed in case rubbish falls into, after the distributor water pressure test pipe joint surplus to remove be to make the key issue that will solve, the problem that exists is at present, as shown in Figure 1:

1. the boring on the dome head: inclined pipe 3 is a ball inclined-plane with end socket 2 contact positions, and directly drill can not be located on the ball inclined-plane;

2. pipe joint groove and processing after sphere cooperates: because of end socket 2 usefulness steel plates are suppressed, there is some difference for the drop at inclined pipe 3 groove places and figure paper size, drop by hole outer wall A point and B point place on the theory calculating end socket is 8mm, and the pipe joint groove is difficult to cooperate with sphere;

3. determine erection sequence, prevent that foreign material from falling into: because distributor is sphere, in a single day foreign material fall in the ball, do not have the possibility of cleaning, so erection sequence is extremely important.

Summary of the invention

The purpose of this invention is to provide a kind of spherical distributor manufacturing process.

For realizing above purpose, technical scheme of the present invention provides a kind of spherical distributor manufacturing process, it is characterized in that, its spherical distributor manufacturing process is:

The first step. difference mounting pipe joint and interior long tube inside and outside the first half end socket top are positioned on the diameter of the first half end socket pipe joint, interior long tube;

Second step. enclose the position of 26 the need punchings of evenly drawing from the inclined pipe pore centerline one at circumferential weld 58mm-61mm place at the latter half end socket, a diameter is polished than the location of holing, the plane of the little 8mm-12mm in inclined pipe aperture by the minimum point B point place of the outer wall in hole on peak A point-the latter half end socket of the outer wall in hole on the latter half end socket that each need be holed, lathe is fixed on the large-diameter steel pipe with the four paws anchor clamps, the latter half end socket is fixed with the four paws anchor clamps, large-diameter steel pipe places on the turning rolls, the drive end socket rotates, drill bit is beaten on the plane that polishes and just can not skidded, and boring just can be finished;

The 3rd goes on foot. and the hole of drilled the latter half end socket is closed pounce on platform, be against the latter half end socket outer wall with angle square, measure A point and B point with ruler again, obtain the drop size that A point and B are ordered, the drop size that actual measurement A point and B are ordered is as the drop size of processing the inclined-plane of locating in the inclined pipe aperture, with the inclined-plane of milling machine processing inclined pipe, groove is processed with boring machine;

The 4th step. outside the latter half end socket bottom, reduced pipe is installed, clamp reduced pipe with deflection machine then, short tube in the latter half end socket bottom, installing, make reduced pipe and interior short tube and pipe joint and interior long tube on same straight line, first plectane is installed again, and in the latter half end socket welding center plectane with holes, make center plectane with holes be in the latter half end socket one circle each circle hole below, and vertical with interior long tube with reduced pipe, interior short tube, pipe joint;

The 5th step. inclined pipe is connect with each eyelet welding that the latter half end socket one encloses respectively, use location mandril to guarantee installation dimension;

The 6th step. at last that the first half end socket and the latter half end socket is involutory, adopt weldering girth weld automatically between the first half end socket and the latter half end socket;

The 7th step. the mouth of pipe at inclined pipe, pipe joint and the reduced pipe of spherical distributor is installed water pressure test shrouding, carries out the water pressure test of spherical distributor;

The 8th step. remove water pressure test shrouding with portable cutters, remove surplus with the blade row of band locating piece again, the pipe end groove of processing inclined pipe, pipe joint and reduced pipe.

The present invention carries out the drill bit location by the A-B place polishing one that need hole at each than the plane of the little 8mm-10mm in inclined pipe aperture, has solved spherical distributor dome head boring problem in manufacture process; By obtaining the drop size that A point and B are ordered, the drop size that actual measurement A point and B are ordered has solved the matching problem of inclined pipe groove and end socket as the drop size of processing the inclined-plane of locating in the inclined pipe aperture; Solve the problem that inner anti-rubbish falls into by optimization that order is installed and the blade row removal pipe joint surplus that adopts the band locating piece.

Advantage of the present invention is the problem that has solved production domesticization, has saved manufacturing cost.
