Abstract

The utility model relates to a sealing device for hydraulic tests. The provided sealing device has the characteristics of reusability, convenience in both mounting and dismounting and simple structure. The technical scheme is as follows: the sealing device for the hydraulic tests is characterized by comprising a cover plate, a seal ring, a fixing ring and a plurality of axial bolts, wherein the cover plate is used for covering an equipment connecting pipe, the seal ring is positioned between the cover plate and the equipment connecting pipe, the fixing ring is fixed on the equipment connecting pipe, and the plurality of axial bolts are used for connecting the cover plate with the fixing ring so as to produce axial pretightening force for the cover plate.

Description

A kind of seal arrangement of the hydrostatic test
Technical field
The utility model relates to a kind of pressure test device, specifically a kind of seal arrangement of pressure test.
Background technique
The hydrostatic test is to carry out the pressure test higher than working pressure take water as medium and to bearing device, its objective is leakproofness and the compressive strength of check bearing device.Known according to Pascal's law, be added in the pressure size being closed on liquid and by liquid, to all directions, transmitted unchangeably.When carrying out the hydrostatic test, if seepage will occur at this position when certain position of bearing device exists tiny hole, when the mechanical strength at this position is weak, also will cause distortion or damage.For there is potential safety hazard after the hydrostatic test, can take in advance corresponding measure to process, to promote reliability and the working life of bearing device.
At present carrying out before the hydrostatic test, the adapter of bearing device will be designed to certain length (being longer than actual demand), and welded cover plate, so that bearing device is sealed, also will cut off unnecessary adapter and cover plate, and the cutting surface of butt tube polishes flat after off-test on adapter end face.So not only increased working strength, and spillage of material is more serious, has greatly reduced manufacturing efficiency, therefore need further improvement.
Model utility content
The purpose of this utility model is the deficiency overcoming in above-mentioned background technology, and a kind of seal arrangement of the hydrostatic test is provided, and that sealing device should have is reusable, all features more convenient and simple in structure of installation and removal.
The technical solution of the utility model is: a kind of seal arrangement of the hydrostatic test, is characterized in that: thus comprise the cover plate taken over for closure cap applying apparatus, be positioned at seal ring between taking over of cover plate and equipment, retaining ring that the equipment that is fixed on is taken over and some for being connected cover plate and the retaining ring axial bolts to cover plate generation axial pre tightening force.
Described retaining ring is that a pair of mutual docking and the equipment that is positioned at are taken over the anchor ear on outer peripheral surface.
On described cover plate and anchor ear, be shaped with some through holes that pass through for axial bolts.
On described cover plate inner side end, be shaped with the mounting groove for positioning seal ring.
The beneficial effects of the utility model are:
Thereby the utility model produces an axial force between retaining ring and cover plate by pretension axial bolts, make cover plate can firmly seal up the adapter of bearing device, can remove easily again after completing the hydrostatic test; Therefore, the utility model not only can be reused, and easy to operate, simple in structure, during use, without welding (can design by the physical length of taking over), avoided unnecessary waste of material, and good sealing effect, has promoted the efficiency of the hydrostatic test greatly.

Fig. 3 is right TV structure schematic diagram of the present utility model.
Fig. 4 is left TV structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in the figure, a kind of seal arrangement of the hydrostatic test, comprises cover plate 1, seal ring 4, axial bolts 3 and retaining ring.
Cover plate is taken over 9 opening (right direction that figure takes over) for covering equipment, is generally circular metal plate and makes; Seal ring is positioned at cover plate inner side end and equipment is taken between opening; On the inner side end 1-1 of cover plate, be also shaped with the mounting groove (omitting in figure) of positioning seal ring, the mounting groove of putting into of seal ring can be slided to prevent seal ring.
Retaining ring is fixed on equipment and takes over above, by equipment adapter outer peripheral surface is applied to certain pressure, prevents that retaining ring from moving axially; As shown in FIG., retaining ring is the anchor ear 2 that a pair of mutual docking circularizes, and this interconnects and be positioned at equipment to anchor ear by fixing bolt 2-1 and takes on outer peripheral surface.
Some axial bolts 3 are vertically passed through cover plate and anchor ear; The quantity of axial bolts is generally 4-8 (shown in figure, being 4); On cover plate and anchor ear, be shaped with some through holes that pass through for axial bolts; By pretension axial bolts, axial bolts can produce an axial force between cover plate and anchor ear, because anchor ear is fixed on equipment firmly, takes over and cannot move, thereby therefore this active force closes by tension cover plate the opening that equipment is taken over, and has guaranteed good sealing effect.
Installation and removal method of the present utility model is: carry out before the hydrostatic test, first the equipment that anchor ear is fixed on is taken over, then cover plate is placed on to the aperture position that equipment is taken over, and use axial bolts that cover plate and anchor ear are linked together, finally tighten successively axial bolts (by diagonal method) to strain cover plate; After the hydrostatic test completes, unload successively just detachable lower the utility model of axial bolts and fixing bolt.
