ULTRA-HIGH TEMPERATURE VALVE TEST DEVICE

WIPO Patent Application WO/2017/079859

A1

An ultra-high temperature valve test device, the device performing an intra-pipe high temperature test on the valve (9) to be tested by means of a high temperature medium burning in a pipe, wherein a fire inlet pipe connector (7), a high heat resistant gasket (10) and the valve to be tested (9) are sequentially connected by means of a bolt and a nut assembly (8); a thermocouple (13) in the fire pipe connector (7), a thermocouple connection wire (14), a thermometer (15) and a thermocouple sensor (16) are electrically connected to a computer system (28) in sequence; a fire outlet pipe connector (18), a high heat resistant gasket (22) and an electric high temperature control valve (17) are sequentially connected by means of a bolt and a nut assembly (23); the valve to be tested (9), a temperature test point winding hoop on valve stem (24) and a thermocouple (24) are mechanically connected. The device solves the problems of existing fire resistance tests, wherein only the exterior of the valve is tested, and the testing is not comprehensive. The device is readily usable in valve and pipe manufacturing factories for high temperature testing.
