Tube wall at described hollow bushing is fixed with a tubulose surge chamber in inert gas blow vent place, be provided with the gas-liquid channel that is communicated with the inert gas blow vent in this tubulose surge chamber, one end of this gas-liquid channel is arranged with hardening liquid inlet and inert gas air intake opening by threeway, the other end of this gas-liquid channel is provided with leakage fluid dram, is separately installed with valve on hardening liquid inlet and leakage fluid dram.
Described tubulose surge chamber is right-angled intersection with hollow bushing and is connected.
Described hollow bushing is fastened by the curved cover plate of arc-shaped base that is connected with the tubulose surge chamber and corresponding setting and constitutes, and described inert gas outlet is for being opened in the opening that is used to wear thermocouple wire on the curved cover plate.
The bearing of trend of described opening is axial perpendicular to hollow bushing.
The bearing of trend of described opening is parallel to the axial of hollow bushing.
Described hollow bushing is made by transparent quartz material.
The utility model isolates the useful space of a closed metal sample between two pressure heads by the hollow bushing on two pressure heads that are sleeved on heating power physical simulation experiment machine; test button is enclosed in the hollow bushing; feed inert gas in the space between hollow bushing and two pressure heads that continues by the inert gas air intake opening during use; the inert gas test button of flowing through spills from the opening that wears thermocouple wire; make inert gas flows; thereby need not to enable vacuum chamber; in the subrange between two pressure heads and hollow bushing under the situation about not vacuumizing, form effective inert gas shielding environment; it has cancelled the numerous and diverse operation that vacuumizes repeatedly in vacuum tank; simplified the operation steps of experiment; and by hollow bushing with local space between two pressure heads and external isolation; make the volume of this enclosure space dwindle significantly, thereby reduced the consumption of inert gas.Simultaneously, can provide quenching function by the hardening liquid inlet that is provided with on the surge chamber and leakage fluid dram to test button, when especially adopting shrend, chilled water can pass through the rapid emptying of leakage fluid dram, in hollow bushing, do not stay raffinate, after the experiment of finishing a test button, need not through numerous and diverse subsequent operation is that replaceable test button carries out next one experiment, thereby continuous experiment and quenching have been realized, it has reduced the operation steps of experiment, conventional efficient is greatly improved, significantly reduced experimental cost.
