Problems solved by technology

The problem with this solution is that if a large amount of refrigerant is released from the magnet, the temperature of the release device will drop to around -200 degrees Celsius. After the pressure release of the magnet is completed, the spring cannot compress due to the temperature drop. Full recovery, resulting in failure of the relief device seal

Abstract

The invention discloses a superconducting magnet pressure release valve and a pressure release system. The pressure release valve comprises a valve body. An elastic part with a tensioning function and a partition plate with the middle open are arranged in the valve body. The valve body is divided into an upper cavity and a lower cavity through the partition plate. An air inlet is formed in the upper cavity. An exhaust opening is formed in the lower cavity. An opening sealing plate is arranged in the lower cavity. The opening sealing plate and the elastic part are connected and then attached to the partition plate so as to completely cover the opening portion in the partition plate. According to the superconducting magnet pressure release valve and the pressure release system, a compression resistance spring is replaced by a tension spring for conducting sealing, and therefore the problem of poor sealing performance caused when the rebound amount of the spring is not enough can be effectively solved, and the problem that the release system can not be effectively closed after releasing is completed is solved. In addition, a first check valve and a bypass loop are added to the air inlet of the pressure release valve, and therefore less ultralow temperature media can pass through the pressure release valve, the service life can be prolonged, and reliability can be improved.

Description

technical field [0001] The invention relates to a relief valve and a relief system, in particular to a superconducting magnet pressure relief valve and a pressure relief system. Background technique [0002] The existing inventions of the pressure relief device on the superconducting magnet can be roughly divided into two types: [0003] One is the design of a pressure sensor, a control unit plus a controlled valve, such as a solenoid valve or a pneumatic valve. This design uses a pressure sensor to measure the internal pressure of the magnet, and then judges the measured internal pressure of the magnet through the control unit, and controls the solenoid valve or pneumatic valve to open or close according to the measured pressure. The feature of this solution is that it can precisely control the opening and closing of the solenoid valve or the pneumatic valve, and the control precision is high. However, due to environmental restrictions during use, if the controlled valve ...
