Abstract
The invention belongs to the field of sealing leak detection devices, and particularly relates to a nuclear power station measuring chamber sealing leak detection device. The sealing leak detection device includes a U-shaped clamp 4 and a sealing cover 6. The U-shaped clamp 4 is clamped on a base 1 of a part to be tested, the lower part of the U-shaped clamp is fixed through a U-shaped clamp screw 5, and a sealing pad 7 is arranged between the upper part of the U-shaped clamp and the base 1 of the part to be tested. The inner side of the base 1 of the part to be tested is a cover plate 2 of the part to be tested, and a sealing ring 3 of the part to be tested is arranged between the base 1 of the part to be tested and the cover plate 2 of the part to be tested to achieve an effect of sealing. The sealing cover 6 integrally covers the cover plate 2 of the part to be tested, the lower end of the sealing cover 6 is connected with the U-shaped clamp 4, and an air charging and discharging pipe 8, a handle 9, a pressure gauge 10 and a water inlet pipe 11 are arranged on the upper surface of the sealing cover 6. The sealing leak detection device is low in cost and high in simulation property of validation results, and operation is visual, rapid, and reliable.
Description
Technical field
This technology belongs to sealing leakage detection apparatus field, is specifically related to a kind of nuclear power station and measures cell sealing leakage detection apparatus.
Background technology
In nuclear power station, it is provided with the measurement cell of diameter about 0.8 meter in heap chamber, base, cover plate and sealing ring constitutes seal member.The sealing of its assembling is in the past by checking that dimensional accuracy assesses its quality and sealing property, can not directly verifying its sealing property, other detection apparatus adaptabilities are difficult to satisfied and testing cost is higher, after installation, carrying out water filling checking by acceptance of work method, expense, duration risk are bigger.
Construction features according to this equipment, seal position at it and install sealing detection cover additional, the binding site with risk of leakage is made to be completely in the overlay area of seal closure, place development liquid in seal closure and aerofluxus, pressure apparatus are filled in configuration, equivalent sealing propertytest before this corollary equipment is installed, it is ensured that often overlap the sealing requirements of this equipment.
The present invention, by reasonably arranging, with less cost, can be simulated reactor pit water test, so that whether whether confirmatory measurement cell can be able to leak when reactor pit fills water in advance in workshop.
Summary of the invention
It is an object of the invention to: providing a kind of nuclear power station to measure cell sealing leakage detection apparatus, detection factory inspection reactor pit measures whether little room cover plate leaks.
Technical scheme is as follows: cell sealing leakage detection apparatus measured by a kind of nuclear power station, including parts pedestal to be detected, parts cover plate to be detected, parts sealing ring 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, it is parts cover plate to be detected in the inner side of parts pedestal to be detected, need detection part sealing ring 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 including U-shaped folder screw, described U-shaped folder passes under U-shaped folder screw and is fixed on parts pedestal to be detected.
Also including sealing gasket, it is between U-shaped folder and parts pedestal to be detected.
Also including handle, it is positioned at seal closure upper surface
Also including Pressure gauge, it is positioned at seal closure upper surface.
The remarkable result of the present invention is in that: assay device is processed voluntarily, and cost is low, and verification the verifying results simulation is strong, directly perceived quick reliable.Sealing by less cost confirmatory measurement cell, can in advance by judging the reasonability of structure manufacture and the sealing of cover plate in shop test, the risk of leakage is produced, it is prevented that find after installation to leak the rework cost, the Schedule schema that cause when being substantially reduced reactor pit scene water test.
Accompanying drawing explanation
Fig. 1 is that cell sealing leakage detection apparatus structural representation measured by a kind of nuclear power station of the present invention
In figure: 1 parts pedestal to be detected, 2 parts cover plates to be detected, 3 parts sealing rings to be detected, 4U type folder, 5U type folder screw, 6 seal closures, 7 sealing gaskets, 8 charge and exhaust pipes, 9 handles, 10 Pressure gauges, 11 water inlet pipes, 12 photo tints
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
As it is shown in figure 1, cell sealing leakage detection apparatus measured by a kind of nuclear power station, including U-shaped folder 4, seal closure 6, wherein U-shaped folder 4 is clipped on parts pedestal 1 to be detected, is fixed by U-shaped folder screw 5 below, and has sealing gasket 7 between top and parts pedestal 1 to be detected；It is parts cover plate 2 to be detected in the inner side of parts pedestal 1 to be detected, between them, needs detection part sealing ring 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, Pressure gauge 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 making portion to be detected is covered completely, and above parts cover plate 2 to be detected, constitute a confined space, photo tint 12 is added by water inlet pipe 11, passing into compression gas by charge and exhaust pipe 8 in seal closure, read the pressure in seal closure by Pressure gauge 10, pressure and operating pressure close Air inflating and exhausting valve door 11 quite afterwards.Keeping pressure stability certain time, observe cover plate non-coloring liquid arranged below and ooze out, non-coloring liquid oozes out sign sealing state well, otherwise, indicates poorly sealed.
