An open hole of a steam pocket end socket safety valve pipe socket is in a radial step shape all the time, a pipe socket is in a bending pipe type all the time, the specification is phi168.3X50.8mm, and the material is SA-106C. The subcritical boiler steam pocket end socket safety valve pipe socket is composed of an end socket (1), the end socket is connected with the safety valve pipe socket (2), and a hole (3) is respectively arranged at the centers of the end socket and the safety valve pipe socket. The subcritical boiler steam pocket end socket safety valve pipe socket is used in a subcritical boiler.
Description
Technical field:
the present invention relates to a kind of novel drum head safety valve header assembly, are specifically related to a kind of subcritical boiler drum head safety valve base and processing method.
Background technology:
The beginning of the eighties has been introduced subcritical 600MW forced circulation boiler in
; Independent development at the year ends 80 subcritical 300MW forced circulation and natural circulation boiler; The perforate of its drum head safety valve base is the radial orders ladder type always; Base is a bent-tube boiler always, and its specification is φ 168.3X50.8 mm, and material is SA-106C.Base need hot bending system and curved after need heat treatment.The end socket bore hole needs positioning fixture.When base and end socket assembling, also need positioning fixture.Manufacturing is long assembly period.
Summary of the invention:
the purpose of this invention is to provide a kind of subcritical boiler drum head safety valve base with good and economic, applicability.
Above-mentioned purpose realizes through following technical scheme:
a kind of subcritical boiler drum head safety valve base, its composition comprises: end socket, described end socket connects the safety valve base, at described end socket and described safety valve base center drilling.
The processing method of
a kind of subcritical boiler drum head safety valve base; According to the design feature of drum head, do the method for figure setting-out through three-dimensional pattern plane, mark the intersection of base and end socket; After intersection marks, obtain the length of base; Computing formula is confirmed the relative position of end socket and base earlier, is marked three-view diagram, front view, vertical view, side view; The inside and outside circle that vertical view is drawn in proportion is divided into 16 five equilibriums; Draw 9 projection lines that 16 bisectors and interior circle or cylindrical intersect to front view; Circle or cylindrical and 16 bisectors have 16 intersection points respectively in vertical view, and it is crossing with it that intersection point (interior circle or cylindrical) is drawn the cylindrical of 9 projection line to end sockets since then, measures the vertical range of intersection point to the spherical shell cover center; In side view, be the center of circle, be that radius is done circle with the vertical range of measuring with the spherical shell cover center; Simultaneously the projection line (interior circle or cylindrical) with 16 bisectors intersects, and retouches out two smooth continuous curve by intersection point, draws two stripe shape shapes close and interior circle or cylindrical intersection that size is different; Its intersection point causes front view, in front view, draws two stripe shape shapes close and the circle or the intersection of cylindrical in the size difference equally.
The processing method of
described subcritical boiler drum head safety valve base, base is pressed outwardly deploying, and both having rule is to draw at the base outer surface, and outer surface has bevel for welding, and intersection has two, one of inner surface, one of outer groove; The intersection of its outer surface is of no use, and outer surface has bevel for welding, and intersection will slice off; In vertical view, connect the center of base and spherical shell cover, be the projection that tangent plane is cooked base with this line; Get a view; After the angle of given bevel for welding, the angle line of groove and the outer surface of base intersect a bit, and the center that connects spherical shell cover is so far put and is that justify in the center of circle with the center of spherical shell cover; Can obtain the curve of bevel for welding, end socket and safety valve base are welded together.
Beneficial effect:
1. the present invention is directed to its structure and manufacturing procedure, simplify, and have saved machining fixture, save bend pipe, curved after-baking technology, improve assembling and welding quality, and it is minimum that its cost is dropped to; Have good and economic, applicability.
the present invention can lie in line on the platform, processing pore, assembling base, has saved the jig of processing end socket pore and the jig of assembling base.In order to guarantee welding quality, added between end socket and base that one section φ 60X5mm, 110mm are long, material is the bushing pipe of 20G, after the welding bushing pipe is machined away, take into account the cleaning root of weld.
In November, 2006 end of
this achievement of the present invention, reaction effect is good.Improved operating efficiency.Reached the purpose of expection invention.
