Description
Technical field
The utility model relates to high voltage substation field, particularly relates to a kind of casing seat housing.
Background technique
Casing seat housing is housing important in high voltage substation housing, and Surface Quality, inherent quality and sealing have strict requirement.Traditional casing seat housing is cast housing, is difficult to ensure housing inherent quality and surface quality, easily occurs that some defects are as crackle, pore and slag inclusion etc. in actual production, is thus also difficult to ensure sealing requirements, even causes whole housing to be scrapped.
Summary of the invention
This is practical for the deficiencies in the prior art, proposes a kind of high leak tightness casing seat housing that can ensure housing inherent quality, surface quality and sealing.
The utility model is achieved through the following technical solutions technical goal.
High leak tightness casing seat housing, its improvements are: described high leak tightness casing seat housing is welded unit, comprise flange I, cylindrical shell, spherical shell cover, cartridge module, air-filled pore flange; Described main cylinder two ends are welded and fixed and are connected between flange I, spherical shell cover; Described cartridge module is made up of a cylinder, a drum flange, and a drum flange is fixedly connected on cylinder one end, and the other end of a cylinder to be inserted in a cylinder mounting hole of spherical shell cover outer side surface and to be welded and fixed connection, and the centre of sphere of spherical shell cover is positioned on the axis of a cylinder; Described air-filled pore flange one end is welded and fixed the outer side surface being connected to cylindrical shell.
In said structure, it is 1/2 of cylindrical shell wall thickness δ that described cylinder inserts the degree of depth L propping up cylinder mounting hole.
In said structure, described air-filled pore flange is provided with seam, and seam inserts in the air-filled pore of cylinder lateral wall, is welded and fixed inside and outside air-filled pore flange and cylindrical shell.
The utility model compared with prior art, has following good effect:
1. change cast structure shaping for existing integral cast into welded structure, the problem of casting defect as crackle, pore and slag inclusion etc. can be solved, housing inherent quality, surface quality and sealing can be ensured; Meanwhile, avoid product rejection, save massive casting equipment and mould simultaneously, reduce manufacture cost.
2. a cylinder inserts the degree of depth L of cylindrical shell is 1/2 of cylindrical shell wall thickness δ, the inside fillet that cylinder and cylindrical shell are formed is filled up in welding, welding line structure is allowed to possess higher intensity, weld seam introjection area is not affected after inside fillet polishing is formed R angle, be beneficial in guarantee welding quality, R angle possesses electric field superiority, slotting welding structure can be avoided to weld the release postponing stress and cause product size precise decreasing.
3. air-filled pore flange is provided with seam, seam inserts in the air-filled pore on cylindrical shell, this kind of structure is convenient to the assembling of air-filled pore flange, welding, fills up the inside fillet that air-filled pore flange is formed with cylindrical shell, does not affect weld seam introjection area and ensure welding quality further behind formation R angle of being polished by inside fillet.
