It further include fixed device and sealing device, the sealing device is used to seal the gap between straight pipe and flange,
The fixed device is used to straight pipe being fixed on flange；
It further include end socket, gland and support stick, the upper end of the support stick is fixed on the lower end surface of end socket, the end socket
The upper end of straight pipe is fixed on by gland, and in support stick insertion straight pipe, the lower end of the support stick extends to entrance branch
The lower section of pipe tie point on straight pipe；
Further include the sampling operation window and transfer chamber being arranged on glove box, the sampling operation window include gloves with
And the hand hole on glove box tank wall is set, the hand insertion end of the gloves is connected with hand hole, and the finger end of gloves is located at
Inside glove box, the transfer chamber includes inside hatch door and outboard door, one as glove box tank wall of the inside hatch door
Point, after inside hatch door and outboard door are closed, airtight cavity is formed inside transfer chamber；
After the connection for completing test section ontology and flange, after the connection of end socket and test section ontology, inside hatch door closes
Afterwards, the glove box is closed cavity；
It further include the gas purification system being connected with glove box inner space, the gas purification system is for removing gloves
Oxygen and water in case.
In the present solution, being closed cavity due to obtain the glove box, the sampling operation window actually exists
Hand hole is opened up on the tank wall of glove box, is then installed on the gloves with air-tightness in glove box by the hand hole, is had
The gloves installation form of existing edible fungi inoculation box, the flexible box that the gloves are equivalent to as glove box can be used in body installation form
Wall, operator are placed in gloves by hand, realize and carry out transfer operation to the corrosion sample in glove box, in transfer chamber；By
It is closed cavity in obtain the glove box, the flange is solderable to be connected on bottom plate, realizes flange and bottom using girth joint
The sealing of plate joint face also can be used flange and connect with bed bolt, and setting gasket is realized on flange and bottom plate joint face
Sealing.
The fixed device and sealing device may be configured as: fixed device and sealing device pass through following three component realities
Existing: locking cap, connection bolt and sealing ring, the sealing ring are set in the gap between straight pipe and flange, the fixation
For cap by connection bolt and flanged joint, and after connecting bolt fastening, locking cap applies extruding force to sealing ring, passes through sealing
Circle realizes the sealing in gap between straight pipe and flange, realizes the fixed company between test section ontology and flange by sealing ring
It connects.It may be configured as on flange using such mode since the frictional force of the sealing ring and straight pipe and flange of needs is larger
Centre bore is the stepped hole with a step, and the big end of stepped hole is upward, in this way, providing bigger pressure for sealing ring

Power.Preferably, also may be configured as sealing device includes sealed pressure pad, connection bolt and sealing ring, is sealed in this scheme
Pressure pad substitute above scheme in locking cap effect, under the action of connect bolt pressure holding gasket to obtain sealing surface,
The difference is that the fixation device in this scheme is including fixing since sealed pressure pad is by connecting bolt and flange rigid connection
Cap, the locking cap use the nut that is such as threadedly coupled with straight pipe, be supported on sealed pressure pad by the lower end of locking cap or
On flange, provide for test section ontology relative to the reliable fixed constraint of flange.
The transfer chamber may be configured as include tubular cabin and inside hatch door for being connected to cabin side and
For being connected to the outboard door of the cabin other side, the receiving that cabin, inside hatch door, outboard door three surround transfer chamber is empty
Between, meanwhile, inside hatch door is while as glove box side wall a part, as being isolated for both glove box and transfer chambers space
Component, outboard door is as the hatch door between transfer chamber inner space and present apparatus external environment.
Gas purification system for removing oxygen and water, have in the prior art the device for being largely used to realize gas deoxygenation and
The device of water removal, as those skilled in the art, so that purpose can be realized in glove box internal gas gas coming through purification system.
The present apparatus can complete according to the following steps corrosion sample corrosion test when specifically used:
S1, the connection for completing test section ontology and flange, specifically: pass through sealing device and fixed device provided above
It realizes；
The connection of corrosion sample and support stick is completed, specifically: complete the connection of corrosion sample, support stick, end socket three；
The connection of support stick and test section ontology is completed, specifically: realize end socket in the company of test section ontology using gland
It connects, gland may be configured as being threadedly coupled with test section ontology, is power of the end socket application towards test section ontology by gland, completes
Above-mentioned connection；
S2, starting major loop carry out corrosion test: introducing liquid lead by the region where inlet leg to corrosion sample
Or liquid lead bismuth alloy carries out corrosion test, above-mentioned major loop is to provide the equipment of liquid lead or liquid lead bismuth alloy, also may be used
It is interpreted as accordingly supplying the pipeline of liquid lead or liquid lead bismuth alloy；
S3, after completing corrosion test, by way of above mentioning corrosion sample, corrosion sample is placed in glove box, and
Corrosion sample is placed in front of glove box, by gas purification system, removes oxygen and water in glove box；
S4, pass through sampling operation window, complete the separation of corrosion sample and support stick, then open inside hatch door, it will be rotten
Sample is lost by being transferred in transfer chamber in glove box, then closes inside hatch door.In this step, end socket is removed to the pact of gland
Beam can be realized by upper pressure-raising lid and be transferred to corrosion sample in glove box by test section ontology, in glove box anaerobic, nothing
In the environment of water or few oxygen, few water, the separation of corrosion sample and support stick is completed, inside hatch door is then opened, sample will be corroded
Inside hatch door is closed after being transferred in transfer chamber；
S5, by taking out corrosion sample in described device: operator by outboard door will corrosion sample from transfer chamber
It takes out.
The present invention, which is controlled sampling process by gas purification system and is in anaerobic anhydrous steam always or lacks oxygen, lacks water steaming
In compression ring border, avoids or vapor and oxygen is avoided to impact specimen surface pattern as far as possible, so that it is guaranteed that test result
Accuracy and reliability.
The present invention compresses test section bodies top using end socket and realizes the sealing of leakage test section ontology, using sealing device and
Fixed device realizes sealing and fixing between test section ontology and glove box, using welding manner or is bolted cooperation sealing
Form of pad etc. realizes the sealing between flange and glove box, not only can guarantee that experimental rig integral sealing is reliable, meets high temperature
Operation demand, while corresponding construction is simple, corresponding sealing or seal assembly can facilitate acquisition, respectively be easy to cause the group of seal leakage
Detachable and interchangeable at component, the later period is maintainable strong, can greatly save cost.
Test section ontology inlet leg of the present invention is located at the top of corrosion sample, in inlet leg nozzle and test
