Background technology
At present, hydrogen cooled generator stator is mostly to use hydrogen outer cooling closed cycle system, and cooling medium is hydrogen, due to hydrogen
Permeability is very strong, and usual temperature measurement element of hydrogen-cooling generator is passed outside electric generator casing, temperature element exists in addition by fabrication hole
In fabrication hole, it can also be sealed at place with silicon rubber, to prevent hydrogen gas leakage.But due in hydrogen cooled generator maintenance process
In, temperature measurement element of hydrogen-cooling generator needs to carry out inspection replacing, and traditional scheme be can not be close to silicon rubber in fabrication hole in time
Big envelope detects, and after can only waiting until generator pressurising, detection leakage detection could be carried out, in addition, temperature measurement element of hydrogen-cooling generator lead exists
It is mostly to use pyramidal structure at wire hole, the connection of the rubber insulation sleeve by being enclosed on tapered post, to ensure temperature element
The insulation against ground performance and the sealing property to hydrogen of terminal plate.Often rubber insulation sleeve is caused to squeeze in actual maintenance process
Compressive strain, along with tapered rubber blanket is acted in generator by high temperature and oil immersion for a long time, it is very easy to aging and loosens, rise
Less than due sealing effectiveness.The rubber insulation sleeve sealing in the temperature element in generator fabrication hole can not be examined in time
Survey, could be detected after generator pressurising can only being waited until, once it is poorly sealed close, gas in generator machine is filled again
After putting, leak source is reprocessed, the efficiency that wastes time and energy is low.
The content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of easy to detect, efficiency high and operation
The airtight experimental provision of reliable temperature measurement element of hydrogen-cooling generator lead collar.
In order to realize above-mentioned technical purpose, the technical solution of the utility model is：
Temperature measurement element of hydrogen-cooling generator lead collar air tightness tester, it includes sealing drum, pressure gauge, tee pipe fitting and control
Valve processed, described sealing drum are that one end is closed and the other end has the tubular structure of opening, one on the tee pipe fitting main line
Port is connected with sealing drum side wall and inside communication seals cylinder, and the another port on the tee pipe fitting main line connects with control valve
Connect, described control valve is connected and controlled the keying that source gas exports with source of the gas, and the tee pipe fitting is positioned at the port of bypass
It is connected with pressure gauge.
Further, the handle of auxiliary hand-held is additionally provided with the side wall of described sealing drum.
Further, the sealing drum is located at ring flange of the end of openend provided with auxiliary installation.
Preferably, described ring flange is provided with sealing ring.
Further, described control valve is stainless steel needle-like valve.
Further, described control valve is connected by a jointing with source of the gas.
Preferably, described jointing is hermetic collar.
Preferably, it is additionally provided with connecting tube between described jointing and source of the gas
Using above-mentioned technical scheme, reviewer only needs when carrying out airtight detection to temperature measurement element of hydrogen-cooling generator
The openend of sealing drum is located at, then seal closure is set using the tight fit of ring flange and sealing ring, is then turned on
The gas of source of the gas is passed through in sealing drum by control valve, is monitored air pressure change by pressure valve to judge whether air-tightness is good
It is good, after gas is passed through a period of time, when the pressure registration of pressure valve is still unstable fluctuation status, you can judge lead collar
Sealing it is bad.
Brief description of the drawings
The utility model is further elaborated with reference to the accompanying drawings and detailed description：
Fig. 1 is the brief configuration schematic diagram of the utility model device.
Embodiment
As shown in figure 1, the utility model device includes sealing drum 6, pressure gauge 5, tee pipe fitting 4 and control valve 3, it is described
Sealing drum 6 is that one end is closed and the other end has the tubular structure of opening, Single port and sealing on the main line of tee pipe fitting 4
Inside the connection of 6 side walls of cylinder and communication seals cylinder 6, the another port on the main line of tee pipe fitting 4 is connected with control valve 3, described
Control valve 3 be connected with source of the gas and control source gas export keying, the tee pipe fitting 4 positioned at bypass port and pressure
Table 5 connects, wherein, the handle 7 for aiding in hand-held is additionally provided with the side wall of sealing drum 6, sealing drum 6 is located at the end of openend
It is provided with the ring flange 8 of auxiliary installation, it is preferred that described ring flange 8 is provided with sealing ring 9, and wherein tee pipe fitting 4 can be
Stainless steel.
In addition, described control valve 3 can be stainless pin type valve, control valve 3 is connected by a jointing 2 with source of the gas
Connect, it is preferred that described jointing 2 is hermetic collar, can also pass through the company of setting between described jointing 2 and source of the gas
Adapter 1 is easy to the connection of control valve 3 and source of the gas to coordinate, in addition, described source of the gas can be nitrogen pot filled with nitrogen or
