Superheated liquid overpressure relief experimental device

Abstract

The invention relates to a superheated liquid over-pressure relief experiment device comprising a pressure container and a computer control system. A heating electrode is installed inside the pressure container; and an injection ball valve and an emptying ball valve are arranged at a lower sealing head of the pressure container. A Temperature sensor, a pressure transmitter, a thermometer, a pressure gauge, an ultrasonic level gauge, and a magnetic float level meter are installed at the pressure container. Three adapters are arranged at an upper sealing head of the pressure container; the central adapter is a solenoid valve adapter; and each of the other two adapter at the two sides is branched to form four branch adapters; the branch adapters at one side are provided with four groups of pressure relief ball value and safety valve combined units; and the branch adapters at the other side are provided with four groups of ball valve and explosion plate combination units; and a solenoid valve is installed at the solenoid valve adapter. The solenoid valve, the temperature sensor, the pressure transmitter, and the ultrasonic level gauge are connected with corresponding controllers; and all controllers are connected with the computer control system. According to the invention, the experiment staff can complete testing in a safety range; and the security is high.

Description

technical field [0001] The invention relates to an experimental device for studying the BLEVE phenomenon and the working phenomenon and mechanism of safety relief devices such as safety valves and burst discs, in particular to an experimental device for superheated liquid overpressure relief. Background technique [0002] Pressure vessels are widely used in various sectors of industrial production such as petrochemicals, biopharmaceuticals, and food processing; at the same time, pressure vessels such as liquefied petroleum gas tanks are also widely used in residents' lives. However, with the passage of time, pressure vessels serving in petroleum, chemical, heat, gas and other industrial production sectors have become serious safety hazards due to corrosion problems, posing a serious threat to the national economy and the safety of people's lives and properties . Due to corrosion and other reasons, the in-service pressure vessel containing superheated liquid will have pittin...
