Embodiment Construction

[0028] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] like Figure 6 and Figure 7 As shown, the manufacturing method of the pressure-bearing equipment large-diameter connecting ball lacking water pressure sealing method according to the present invention includes the following steps:

[0030] Step 1, mark the large hole of the convex head;

[0031] Step 2, gas cutting the large hole of the convex head to obtain the raw material for the water pressure sealing of the ball;

[0032] Step 3, machining the ball without water pressure and sealing the welding groove or outer circle;

[0033] Step 4, before the hydraulic test of the pressure-bearing equipment, weld the large-diameter tube ball lack of hydraulic pressure cover;

[0034] Step 5: After the hydraulic test of the pressure-bearing equipment, the water pressure cover of the ball is cut off.

[0035] Further: The water pressure seal ...

Abstract

The invention discloses a manufacturing method for a segment hydraulic cover of a large-caliber joint pipe of pressure-bearing equipment, and belongs to the technical field of hydraulic covers of large-caliber joint pipes of pressure-bearing equipment such as a boiler and a pressure vessel. The manufacturing method for the segment hydraulic cover of the large-caliber joint pipe of the pressure-bearing equipment is the improvement and innovation of existing design structures and manufacturing methods of hydraulic flat covers of large-caliber joint pipes in the past and turns waste into wealth and makes comprehensive use. The segment hydraulic cover is innovatively invented: segment waste materials generated by gas cutting of large holes of convex heads of the pressure-bearing equipment areutilized, and material cost is reduced.

Description

technical field [0001] The invention relates to a method for manufacturing a cap, in particular to a method for capping a large-diameter connecting ball of a pressure-bearing equipment without water pressure, and belongs to the technical field of hydraulic sealing of a large-diameter connecting pipe of pressure-bearing equipment such as boilers and pressure vessels. Background technique [0002] For a long time, although the large-caliber welded water pressure thick plate flat cover of pressure equipment such as boilers and pressure vessels is simple to make, it needs to consume a large amount of steel plate materials. See figure 1 . However, the ball gaps produced by the large openings of the convex heads of various diameters, wall thicknesses, and materials of pressure equipment are not used and discarded. As a result, the design structure and manufacturing technology of the large-diameter nozzle hydraulic sealing cover of the pressure-bearing equipment are single and out...
