INSTALLATION FOR MECHANICAL TESTING OF MATERIALS AT HIGH TEMPERATURES AND UNDER HIGH PRESSURES Russian patent published in 2022 - IPC G01N3/18 

FIELD: testing equipment.

SUBSTANCE: invention relates to the processing of materials by high pressure, in particular, devices for testing samples for tension, torsion, compression under high pressure and at high temperatures. The installation contains a container with a working chamber located in it, filled with a working medium, with grips for the sample, a loading mechanism, a heater made in the form of a spiral and located in the working chamber in such a way that the sample is inside the spiral, means of feeding the working medium and control and measuring equipment. A liquid medium is used as a working medium. The loading mechanism is made in the form of upper and lower plungers. The heater, made in the form of a spiral with a heat-insulating coating, is placed in a ceramic tube, while one of the ends of the spiral is connected to the upper gripper housing, the other is placed in an electrically insulated hole of the lower gripper and is designed for periodic interaction with contacts installed in the lower plunger. The means of control and measuring equipment are made in the form of a thermocouple, the junction of which is placed in the cavity of a ceramic tube, and the output through the electrically insulated hole of the upper grip is connected to the electrical contacts of the upper plunger. The contacts of the upper and lower plunger are cone-shaped.

EFFECT: ensuring reliability and expanding technological capabilities due to the absence of restrictions on reaching high temperatures and pressures.
