Abstract
The invention provides an internal expanding type hydraulic pressure tool for a large-diameter adapter tube and a method. The inner diameter of the large-diameter adapter tube on a spherical seal head of a high-pressure heater which is produced currently is commonly larger than the diameter of a manhole, so that when the high-pressure heater is subjected to a hydraulic pressure test, a conventional hydraulic pressure tooling cannot enter the bottom of the adapter tube from the manhole for clamping. The tool comprises a hydraulic pressure cylinder (1) which is connected with the adapter tube (6), wherein semi-ring stop blocks (2) are clamped on the hydraulic pressure cylinder; connecting plates (3) are arranged on the semi-ring stop blocks and fixed by bolts I (5) and gaskets I (4); the other end of the hydraulic pressure cylinder is connected with press rings (8) through bolts II (10) and gaskets II (9); a seal ring (7) is mounted between the edge of each press ring and the hydraulic pressure cylinder; an end press plate (11) is mounted at one end part of the adapter tube and connected with the press rings through a stud (12); and a nut III (14) and a gasket III (13) are arranged on the stud. The invention applies to the internal expanding type hydraulic pressure tool for the adapter tube.
Description
technical field:
the present invention relates to a kind of large diameter nozzle internal-expansion type Tool for Hydraulic and method.
background technology:
on the high-pressure heater dome head of current production, the internal diameter of large diameter pipe adapter is generally all greater than people's bore dia, when carrying out the hydraulic testing to it, conventional hydraulic pressure frock cannot enter adapter bottom from manhole and be installed, usually the form of welding stifle is adopted to meet hydraulic testing requirement in the case, after end to be tested, stifle gas cutting is fallen, then machine is carried out to pipe end add.
the defect of the welding stifle form hydraulic testing mainly contains following several respects:
first, the adapter process redundancy of requirement is many, and waste material, increases cost.In order to leave certain space to welding stifle, and still leave reprocessing surplus after making gas cutting fall stifle, before this just requires the hydraulic testing, adapter pipe end will leave abundant process redundancy, and surplus too much causes cost of products to increase.After high-pressure heater Total Product hydraulic pressure, reprocessing pipe ends groove, difficulty of processing is large, and existing machining equipment cannot meet processing request.Secondly, this hydraulic testing mode wastes time and energy.Compared with conventional water pressure end cap leakage test, this mode adds processing and manufacturing stifle, at multiple working procedures such as pipe end welding stifle, weld seam detection, gas cutting stifle, tube end machings, extends manufacture cycle, increases manufacturing cost.Likely there is potential safety hazard, stifle welding quality directly can affect the security of the hydraulic testing.
summary of the invention:
the object of the present invention is to provide a kind of large diameter nozzle internal-expansion type Tool for Hydraulic and method.
the object of the present invention is achieved like this:
a kind of large diameter nozzle internal-expansion type Tool for Hydraulic, its composition comprises: hydraulic pressure cylindrical shell, described hydraulic pressure cylindrical shell is connected with adapter, described hydraulic pressure cylindrical shell has been installed semi-ring block, described semi-ring block is provided with web joint, described web joint bolt one and packing ring one are fixed, the described hydraulic pressure cylindrical shell other end is connected with pressure ring with packing ring two by bolt two, between described pressure ring edge and described hydraulic pressure cylindrical shell, O-ring seal is installed, in the end of described adapter, end clamp plate is installed, described end clamp plate is connected by stud bolt with described pressure ring, described stud bolt is provided with nut three and packing ring three.
large diameter nozzle internal-expansion type Tool for Hydraulic, described hydraulic pressure cylindrical shell has cavity, and described hydraulic pressure cylindrical shell is provided with limbers; Described pressure ring and described end clamp plate are all provided with a loop through hole.
a using method for large diameter nozzle internal-expansion type Tool for Hydraulic, its concrete operation method is as follows:
(1) first two pieces of semi-ring blocks are put in end socket by manhole;
(2) by hydraulic pressure cylindrical shell by adapter loading, and the semi-ring block that is installed on hydraulic pressure cylindrical shell;
(3) O-ring seal is installed, and adjusts bolt and utilize pressure ring swelling O-ring seal;
(4) finally fill end clamp plate, a whole set of frock is fixed in adapter by set nut.
beneficial effect:
1. the baffle ring form of two Houghs is changed in the monoblock type capping of in the past bearing axial force by the present invention, makes that this Tool for Hydraulic is reasonable in design, structure is simple, easy to operate, solves the difficult problem that the large diameter nozzle hydraulic testing cannot use Tool for Hydraulic.
decrease product and reserve process redundancy, save the hydraulic testing time, avoid pipe end secondary processing operation, decrease the machining period because secondary processing produces and expense, improve hydraulic testing security.
