Description
Technical field
This technology belongs to sealing leakage detection apparatus field, is specifically related to a kind of nuclear power station measuring chamberlet sealing leakage detection apparatus.
Background technology
In nuclear power station, be furnished with the measuring chamberlet of diameter about 0.8 meter in heap chamber, form seal member by base, cover plate and O-ring seal.The sealing of its assembling is in the past by checking that dimensional accuracy assesses its quality and sealing property, can not directly verify its sealing property, other checkout equipment adaptability are difficult to meet and testing cost is higher, after installation, carry out water filling checking by acceptance of work method, expense, duration risk are larger.
According to the design feature of this equipment, sealing detection cover is installed additional at its sealing position, the binding site with risk of leakage is made to be in the overlay area of seal closure completely, place video picture liquid in seal closure and configure and fill exhaust, pressure apparatus, equivalent sealing propertytest before installing this support equipment, guarantees the sealing requirements of often overlapping this equipment.
Whether whether the utility model, by reasonably arranging, with less cost, can carry out mock-up reactor tank water leakage test in workshop, can be able to leak with confirmatory measurement cell when reactor pit fills water in advance.
Summary of the invention
Whether the purpose of this utility model is: provide a kind of nuclear power station measuring chamberlet sealing leakage detection apparatus, detect factory inspection reactor pit measuring chamberlet cover plate and leak.
The technical solution of the utility model is as follows: a kind of nuclear power station measuring chamberlet sealing leakage detection apparatus, comprise parts pedestal to be detected, parts cover plate to be detected, seal parts circle to be detected, U-shaped folder, seal closure, charge and exhaust pipe, water inlet pipe, photo tint, wherein U-shaped folder is clipped on parts pedestal to be detected, be parts cover plate to be detected in the inner side of parts pedestal to be detected, need detection part O-ring seal between them, play the effect of sealing; Seal closure piece cover is on parts cover plate to be detected, and its lower end is connected with U-shaped folder, has charge and exhaust pipe, water inlet pipe at seal closure upper surface; During detection, photo tint is added by water inlet pipe.
Also comprise U-shaped folder screw, described U-shaped folder below is fixed on parts pedestal to be detected by U-shaped folder screw.
Also comprise sealing gasket, it is between U-shaped folder and parts pedestal to be detected.
Also comprise handle, it is positioned at seal closure upper surface.
Also comprise tensimeter, it is positioned at seal closure upper surface.
Remarkable result of the present utility model is: test unit is processed voluntarily, and cost is low, and verification the verifying results simulation is strong, directly perceived quick reliable.By the sealing of less cost confirmatory measurement cell, can in advance by judging the rationality of structure manufacture and the sealing of cover plate in shop test, produce the risk of leaking when greatly reducing reactor pit scene water test, prevent that rear discovery is installed and leak the rework cost, the Schedule schema that cause.
Accompanying drawing explanation
Fig. 1 is a kind of nuclear power station measuring chamberlet sealing leakage detection apparatus structural representation described in the utility model
In figure: 1 parts pedestal to be detected, 2 parts cover plates to be detected, 3 seal parts circles to be detected, 4U type folder, 5U type folder screw, 6 seal closures, 7 sealing gaskets, 8 charge and exhaust pipes, 9 handles, 10 tensimeters, 11 water inlet pipes, 12 photo tints
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of nuclear power station measuring chamberlet sealing leakage detection apparatus, comprise U-shaped folder 4, seal closure 6, wherein U-shaped folder 4 is clipped on parts pedestal 1 to be detected, fixed by U-shaped folder screw 5 below it, and between top and parts pedestal 1 to be detected, have sealing gasket 7; Be parts cover plate 2 to be detected in the inner side of parts pedestal 1 to be detected, between them, need detection part O-ring seal 3, play the effect of sealing; Seal closure 6 piece cover is on parts cover plate 2 to be detected, and its lower end is connected with U-shaped folder 4, has charge and exhaust pipe 8, handle 9, tensimeter 10, water inlet pipe 11 at seal closure 6 upper surface.
During detection, first U-shaped folder 4, seal closure 6 are fixed, the detection site in portion to be detected is covered completely, and a confined space is formed above parts cover plate 2 to be detected, photo tint 12 is added by water inlet pipe 11, in seal closure, pass into pressure gas by charge and exhaust pipe 8, read the pressure in seal closure by tensimeter 10, pressure and working pressure close Air inflating and exhausting valve door 11 quite afterwards.Keep pressure stability certain hour, observe below cover plate and ooze out with or without pigmented fluids, non-coloring liquid oozes out and indicates sealing state well, otherwise, indicate poorly sealed.
