Abstract
The utility model discloses a local pressure testing structure for a pressure vessel. The local pressure testing structure comprises a blind plate installed on a newly added flange jointing pipe orifice and a pressure testing box installed on the wall of the pressure vessel, wherein the pressure testing box, a newly added flange jointing pipe and the blind plate form a closed pressure testing space together. According to the local pressure testing structure, by checking the strength and the tightness of a transformation position of equipment at the transformation position of the equipment by virtue of a local water pressure test, the water consumption is lowered, the whole construction time is reduced, the problem of short time during maintenance construction on the premise of rules allowance is solved, a mode of the existing vessel that the water is needed to be filled in the vessel to test the pressure after the vessel is locally changed is changed, and the testing cost is greatly reduced. Moreover, the local pressure testing structure is of a simple structure and is conveniently used.
Description
Technical field
The utility model relates to a kind of pressure testing structure of pressure vessel, particularly relates to a kind of local pressure testing structure of pressure vessel.
Background technology
Some technological process of petrochemical production device is when optimizing or changing, need carry out local transformation to some pressure vessels (such as tower or storage tank etc.), such as increase new adapter or other annexes at equipment, also or the original adapter bore of change equipment.The pressure vessel part is transformed, need follow the pressure vessel manufacturing standard, as GB150 and GB151, and carry out informing of pressure vessel transformation to local relevant departments.According to the related specifications that pressure vessel is made, scrap build construction/make to finish and will carry out intensity and leak test afterwards, Chang Gui way was that equipment is carried out the whole hydraulic testing in the past.The equipment of transforming is the equipment that has come into operation in the device, generally finishes the construction content during the device shut-down (breakdown) mainteance.Because equipment comes into operation, the insulation of equipment, pipeline, internals etc. are all finished, are exactly that the equipment nozzle flange is removed and blind plate is installed to the difficulty of the whole pressure testing maximum of equipment, secondly are exactly water on the whole and the draining of equipment, above-mentioned 2 except the duration being had the very big influence, the manpower, facility and the material that consume also are huge, therefore, are badly in need of the local pressure testing structure of exploitation pressure vessel.
The utility model content
The utility model provides a kind of local pressure testing structure of pressure vessel for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: a kind of local pressure testing structure of pressure vessel, comprise the blind plate and the pressure testing box that is installed on the pressure vessel wall that are installed on the newly-increased flange adapter mouth of pipe, described pressure testing box, described newly-increased flange are taken over and the common airtight pressure testing space that forms of described blind plate.
Described pressure testing box is welded on the inwall of described pressure vessel.
Described pressure testing box is welded on the outer wall of described pressure vessel.
Outer wall at described pressure vessel is welded with stiffening ring, and described stiffening ring suit also is welded on the outside that described newly-increased flange is taken over.
Advantage and the good effect that the utlity model has are: because behind the local flow improvement, influence to the equipment bulk strength can be ignored substantially, the utility model is by carrying out intensity and the tightness thereof that the local hydraulic testing comes inspection machine transformation place in scrap build place, reduced the consumption of water, reduced the integral construction time, under the prerequisite that rules allow, solved problem it is pressed for time in the maintenance construction, changed the pattern that needs to be full of the water pressure testing behind local moving the changing of container in the past, the pressure testing cost reduced greatly.And the utility model is simple in structure, and is easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model first scheme;
Fig. 2 is the structural representation of the utility model alternative plan.
Among the figure: 1, tensimeter; 2, atmospheric valve; 3, blind plate; 4, newly-increased flange is taken over; 5, pressure testing box; 6, pressure vessel wall; 7, stiffening ring.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, a kind of local pressure testing structure of pressure vessel, comprise that being installed in newly-increased flange takes over the blind plate 3 on 4 mouths of pipe and be installed in pressure testing box 5 on the pressure vessel wall 6, described pressure testing box 5, described newly-increased flange take over 4 and the described blind plate 3 common airtight pressure testing spaces that form.By at the parts that form airtight pressure testing space the pressure testing material being installed, as pressure testing valve 8, tensimeter 1 and atmospheric valve 2 etc., utilize confined space to carry out the pressure testing operation, realize the local pressure testing of pressure vessel.
See also Fig. 1, described pressure testing box 5 is welded on the inwall of described pressure vessel.See also Fig. 2, described pressure testing box 5 is welded on the outer wall of described pressure vessel.No matter pressure testing box 5 is contained on the outer wall of pressure vessel or on the inwall, all need be welded with stiffening ring 7 at the outer wall of described pressure vessel, described stiffening ring 7 suits also are welded on described newly-increased flange and take over 4 outside.
Above-mentioned pressure testing box should comprise all heat-affected zones of transforming weld, by this pressure testing box is carried out intensity and the tightness that transformation place is checked in the hydraulic testing.When the pressure testing box is installed, for general individual layer wall container, the welding of carrying out the pressure testing box at container outer wall or inwall all can, at inwall welding pressure testing box, the externally distortion of checkout facility transformation place or tightness then should be in the internal tank inspections at outer wall welding pressure testing box.For the composite bed container, in general, should carry out the welding of pressure testing box at the carbon steel layer.
Although by reference to the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
