A subcritical 600 MW forced circulation boiler is introduced at the beginning of the 80s, and a subcritical 300 MW forced circulation and natural circulation boiler is autonomously developed at the end of the 80s. 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 phi168.3*50.8mm, 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, be specifically related to a kind of subcritical boiler drum head safety valve pipe base and processing method.
background technology:
introduce subcritical 600MW forced circulation boiler the beginning of the eighties, independent development subcritical 300MW forced circulation and natural circulation boiler at the end of 80, the perforate of its drum head safety valve base is radial orders ladder type always, base is bent-tube boiler always, its specification is φ 168.3X50.8 mm, and material is SA-106C.Base need hot bending system and curved after need heat treatment.End socket bore hole needs positioning fixture.When base and end socket assembling, also need positioning fixture.Manufacture assembly period long.
summary of the invention:
the object of this invention is to provide and a kind of there is good economy, the subcritical boiler drum head safety valve pipe base of applicability.
above-mentioned object is realized by following technical scheme:
a kind of subcritical boiler drum head safety valve pipe base, its composition comprises: end socket, described end socket connection safety valve base, at described end socket and described safety valve base center drilling, according to the design feature of drum head, done the method for figure setting-out by three-dimensional pattern plane, mark the intersection of base and end socket, after intersection marks, obtain the length of base, the relative position of end socket and base is first determined by computing formula, marks front view, top view, side view, the inside and outside circle drawn in proportion by top view is divided into 16 deciles, inner circle or cylindrical and 16 bisectors have 16 intersection points respectively in a top view, 16 bisectors, 9 projection lines crossing with inner circle or cylindrical are drawn to front view, intersection point is drawn 9 projection lines to the cylindrical of end socket and is intersected with it since then, measure the vertical range of intersection point to spherical shell cover center, in side view with spherical shell cover center for the center of circle, with the vertical range measured for radius does circle, simultaneously crossing with the projection line of 16 bisectors, two smooth curves are described by intersection point, draw two strips close and the inner circle that size is different or cylindrical intersection, its intersection point causes front view, draws the intersection of the different inner circle of the close and size of two strips or cylindrical in front view equally.
the processing method of described subcritical boiler drum head safety valve pipe base, base presses outwardly deploying, and both having rule is draw at base outer surface, and outer surface has bevel for welding, and intersection has two, inner surface one, outer groove one; The intersection not use of its outer surface, outer surface has bevel for welding, and intersection will slice off; In a top view, connect the center of base and spherical shell cover, with this line for tangent plane is cooked the projection of base, obtain a view, after the angle of given bevel for welding, the angle line of groove is more crossing with the outer surface of base, connects the center of spherical shell cover and so far to put and with the center of spherical shell cover for justifying in the center of circle, the curve of bevel for welding can be obtained, end socket and safety valve base are welded together.
beneficial effect:
1. the present invention is directed to its structure and manufacturing procedure, simplify, eliminate machining fixture, save bend pipe, curved after-baking technique, improve assembling and welding quality, its cost is dropped to minimum; There is good economy, applicability.
the present invention can lie in line on platform, processing pore, assembling base, eliminates the jig of processing end socket pore and assembles the jig of base.In order to ensure welding quality, between end socket and base, added one section of φ 60X5mm, 110mm length, material is the bushing pipe of 20G, is machined away by bushing pipe, take into account cleaning root of weld after welding.
this achievement of the present invention terminates in November, 2006, and my company's product is at home widely used so far.Be respectively used to the subcritical engineering of the 600MW such as Tongchuan, Huo Linhe, for the subcritical engineering of the 300MW such as northern Shandong, blue aluminium, reaction effect is good.Improve operating efficiency.Reach the object of expection invention.
accompanying drawing illustrates:
