Abstract

The invention provides a device for detecting and testing a high-temperature valve based on an air heating system. The device comprises an air compressor, a heating tank, a detection device and a buffer tank. The air compressor is connected with the heating tank through a steel pipe. A pressure sensor and a temperature sensor of the heating tank are arranged at the top of the heating tank. An air heater is arranged at the bottom of the heating tank. The heating tank is connected with an inlet of the valve to be tested through a first test pipeline. The first test pipeline is provided with an electric check valve. The detection device comprises a detection table and a test device. The valve to be tested is arranged on the detection table. The test device comprises a high-temperature flow meter, a torque test device, a differential pressure gauge and an ultrasonic leakage detector. An outlet of the valve to be tested is connected with the buffer tank through a second test pipeline. The device can simulate the actual working condition in a factory and detect the high-temperature medium circulation performance of the high-temperature valve.

Description

technical field [0001] The invention belongs to the technical field of mechanical component testing, and in particular relates to a high-temperature valve detection test device and method based on an air heating system. Background technique [0002] Valves are control components in the pipeline fluid delivery system, mainly used to change the passage section and medium flow direction, and have functions such as diversion, cut-off, throttling, check, diversion, overflow and pressure relief. There are many types and specifications of valves used for fluid control, including the simplest globe valve, and various valves used in several complex automatic control systems, including extremely small instrument valves, and industrial pipeline valves with diameters up to 10m. . A large number of applications of industrial valves are after Watt invented the steam engine. In the past 20 or 30 years, due to the needs of petroleum, chemical industry, power stations, metallurgy, ships, nu...
