Abstract

The invention provides a safety valve on-line detector driven by a stepping motor. The safety valve on-line detector comprises a mechanical fixture system used for fixing a detecting device on a safety valve, a stepping motor system used for providing the tension needed for lifting the safety valve, and an electric detecting system used for transmitting feedback data of the stepping motor system and controlling the stepping motor system. The safety valve on-line detector has the advantages that the accuracy and the repeatability of the safety valve on-line detector are higher, the carrying and the mounting are facilitated, the detachment is convenient, the verification is rapid, and the judgment is objective and accurate.

Description

technical field [0001] The invention relates to an on-line detector for a safety valve driven by a stepping motor, in particular to an on-line detector for detecting a spring full-open safety valve in the process industry. Background technique [0002] Pressure-bearing (category) equipment refers to boilers, pressure vessels, pressure pipes and other pressure-bearing special equipment and their safety accessories, which have been widely used in petroleum, chemical, steel, electric power and daily life fields. plays a pivotal role in. The safety valve is an important safety component in the pressure system, which is used to prevent overpressure damage to the equipment and ensure the safe operation and production of the pressure system. During the operation of the safety valve, under the action of physical and chemical factors such as operating pressure, temperature and medium erosion, its set pressure and sealing performance will change, resulting in the safety valve not bei...
