Pipe internal combustion superhigh temperature valve testing apparatus

Abstract

A pipe internal combustion superhigh temperature valve testing apparatus is provided mainly to solve the problem that valve fireproof tests and high-temperature valve tests only through external high temperature are incomprehensive. The high temperature valve testing apparatus performs pipe internal high temperature tests on valves by adopting pipe internal combustion as a high-temperature medium. A fire entry pipe connector is mechanically connected with a bolt and nut assembly, a valve to detected and a high heatproof pad. A pipe connector internal thermocouple is electrically connected with a thermocouple connecting line, a thermometer, a temperature sensor and a computer system. A fire exit pipe connector is mechanically connected with a bolt and nut assembly, an electric high-temperature regulating valve and a high heatproof pad. An iron hoop winding temperature test points on a valve stem is mechanically connected with the valve to be detected and a thermocouple. The apparatus is widely used in valve plants and pipe fitting factories for high temperature experiments.
