Abstract
The utility model relates to an annular header. A header pipe is bent to be an annular shape to form an annular header, the excircle of the header is provided with drainage holes, the pitch of the drainage holes is the same with that of a membrane wall, the size of the drainage holes is the same with the inner diameter of pipes of the membrane wall, the membrane wall is cut off along an outer ring of the annular header, the pipes are aligned and welded with the drainage holes to form a whole, and a hole-opening steel plate is connected with an inner ring of the annular header. By utilizing the annular header, a form of opening a large hole with a pipe-pulling pipe-yielding mode in the past can be replaced. The annular header is simple in structure, good in standardization, low in design and manufacture cost and good in safety.
Description
Technical field
The utility model relates to a kind of annular header.
Background technology
In Technique in Boiler Membrane Water Cooled Wall, often need to open burner aperture, manhole, manhole, feeder hole and industrial television preformed hole, the method in past is that the pipe at opening area must bend to get out of the way the equipment of installing, the number of tubes that equipment bends more greatly is just more, radian is just larger, cost is just higher, and the time of design and check and correction is longer.
Summary of the invention
The purpose of this utility model provides a kind of annular header, improves design efficiency, reduces the design error rate, reduces manufacturing cost, improving production efficiency and product percent of pass.
The utility model is to realize like this, it comprises annular header, fin panel casing, steel plate, it is characterized in that collecting box pipe is bent into annular and forms annular header, be split into round on the cylindrical of annular header, pitch of holes in pattern is identical with the pitch of fin panel casing, and the size of round is identical with fin panel casing pipe internal diameter, and fin panel casing is excised along the annular header outer ring, pipe aligns with round to weld and forms an integral body, is connected with an open pore steel plate at the annular header inner ring.Erection unit needs much holes just to open much holes at steel plate.Just realized the purpose of fin panel casing perforate.
Technique effect of the present utility model is: can replace in the past the form that " trombone slide is by tubular type " opens macropore, major advantage be simple in structure, standardization good, reduce the Design and manufacture cost, security is good.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In the drawings, 1. annular header 2. fin panel casings 3. steel plates.
The specific embodiment
As shown in Figure 1, the utility model is to realize like this, it comprises annular header 1, fin panel casing 2, steel plate 3, collecting box pipe is bent into annular and forms annular header 1, is split into round on the cylindrical of annular header 1, and pitch of holes in pattern is identical with the pitch of fin panel casing 2, the size of round is identical with fin panel casing 2 ips, along the excision of annular header 1 outer ring, pipe aligns with round to weld and forms an integral body, is connected with an open pore steel plate 3 at annular header 1 inner ring with fin panel casing 2.Erection unit needs much holes just to open much holes at steel plate.Just realized the purpose of fin panel casing perforate.
