Abstract
The utility model belongs to a spherical tank manhole which is formed by machining an integral annular forging, and particularly relates to a protruding edge and a flange integrated for a spherical tank manhole, which is characterized that a manhole protruding edge, a transitional section and a manhole flange are arranged on an integral annular forging, and the manhole protruding edge and the manhole flange are connected into a whole through the transitional section and machined into a connecting part. The outer side of the manhole protruding edge is connected with a spherical tank shell plate by welding, and the manhole flange is connected with a blind flange through bolts to fasten the flange cap. The protruding edge and the flange integrated for the spherical tank manhole is formed by machining the integral annular forging, and the manhole protruding edge and the manhole flange are integrally connected, so that materials and manufacturing cost are saved. The protruding edge and the flange integrated for the spherical tank manhole has the advantages that manufacturing time is saved, and bearing safety of the manhole protruding edge is improved.
Description
Technical field
The utility model belongs to a kind of spherical tank manhole that is formed through machine up by integral ring-shaped forging, particularly a kind of spherical tank manhole solid flange flange.
Background technology
The manhole flange of spherical storage tank and manhole flange all are to be welded by two independent parts processes both at home and abroad at present, and two component processing surpluses are big, waste material; The weld seam of two parts welding needs the non-destructive test check, increases inspection cost; Welding and non-destructive test singly do not increase cost, prolong manufacturing schedule yet.
Summary of the invention
The utility model has overcome the defective of above-mentioned existence, and purpose is during for the raw material of manhole parts that practice thrift to make spherical storage tank, cost-cutting, saving worker, and a kind of spherical tank manhole solid flange flange is provided.
The utility model spherical tank manhole solid flange flange content Description:
The utility model spherical tank manhole solid flange flange; It is characterized in that: be that manhole flange, transition phase and the manhole flange that on an integral ring-shaped forging, is provided with formed; Manhole flange and manhole flange are connected as a single entity through transition phase, the disjunctor parts of processing through machine up.
Manhole flange outer sides and spherical tank coverboard are welded to connect, and the manhole flange is connected through bolted with blind flange.
The utility model spherical tank manhole solid flange flange is to be processed by an annular forging piece, is the spherical tank manhole solid flange flange that manhole flange and manhole flange are connected as a single entity, and has saving in material, saves manufacturing cost.When saving worker, improve the advantage of manhole flange pressure-bearing safety.
Description of drawings
Fig. 1 is a spherical tank manhole solid flange flange arrangement scheme drawing
Among the figure: the 1st, manhole flange, the 2nd, transition phase, the 3rd, manhole flange, the 4th, blind flange, the 5th, bolt, the 6th, spherical tank coverboard.
The specific embodiment
The utility model spherical tank manhole solid flange flange is achieved in that below in conjunction with accompanying drawing and specifies.See Fig. 1, spherical tank manhole solid flange flange is that the manhole flange 1 that on an integral ring-shaped forging, is provided with, transition phase 2 and manhole flange 3 are formed, and manhole flange 1 is connected as a single entity through transition phase 2 with manhole flange 3, the disjunctor parts of processing through machine up.
Manhole flange 1 outside and spherical tank coverboard 6 are welded to connect, and manhole flange 3 is connected clamp flange lid 4 with blind flange 4 through bolt 5, reaches the function of spherical tank seal and pressure bearing.
The utility model can be selected 1.6MPa, 2.5MPa, 4.0MPa, 5.0MPa equipressure level other manhole flange and flange for use according to the design pressure of spherical tank; Flange material will be complementary with the spherical tank coverboard.
