High temperature valve detecting and testing system

Abstract

The invention discloses a high temperature valve detecting and testing system, comprising an oil feed pump, an oil storage tank, a pressure pump, a buffer tank, a detecting device and a condensing device, wherein an electric heater and a pressure transmitter are installed on the top part of the oil storage tank; the bottom part of the oil storage tank is connected with the buffer tank through a third trunk pipeline; another pressure transmitter and a temperature sensor are installed on the inner side wall of the buffer tank; the buffer tank is connected with an oil inlet of a to-be-detected valve through a fourth trunk pipeline; the detecting device comprises a detecting table and a torque testing device; the valve rod of the to-be-detected valve is connected with the torque testing device; and the oil outlet of the to-be-detected valve is connected with the oil storage tank through a fifth trunk pipeline, the condensing device and a second trunk pipeline in sequence. The high temperature valve detecting and testing system is simple in structure and convenient to operate; and by the adoption of the detecting and testing system, the resistance coefficient and the torque performance of a high temperature valve and the flow characteristic can be tested, and the leakage amount can be detected.

Description

technical field [0001] The invention relates to a high temperature valve detection test system. Background technique [0002] The valve is the control device of the fluid pipeline. Its basic function is to connect or cut off the circulation of the pipeline medium, change the flow direction of the medium, adjust the pressure and flow of the medium, and protect the normal operation of the equipment in the pipeline. [0003] A large number of industrial valves are used after Watt invented the steam engine. In the past 20 or 30 years, due to the needs of petroleum, chemical industry, power station, metallurgy, shipbuilding, nuclear energy, and the universe, higher requirements have been put forward for valves, prompting people Research and produce high-parameter valves, whose working temperature ranges from ultra-low temperature -269°C to high temperature 1200°C, even as high as 3430°C. [0004] At present, when most domestic valve manufacturers conduct factory inspections of v...

AI Technical Summary

Problems solved by technology

At present, before domestic high-temperature valve companies provide products to the outside world, due to the lack of testing equipment for high-temperature medium flow capacity, they cannot provide corresponding parameter data, such as whether the valve’s switching performance under high-temperature medium is good, whether the leakage is serious, and whether the flow capacity is normal, etc. , which directly affects the core competitiveness of domestic high-temperature valve products
