Abstract

The invention relates to a nuclear power station valve button type temperature acquisition device. The nuclear power station valve button type temperature acquisition device comprises a cylinder, the top of the cylinder is provided with a through hole and a fixing assembly, the cylinder is internally provided with a temperature measurement element, a spring gasket, a fixing box body, a temperature transmitter and a pressing cover in sequence, the temperature measurement element sequentially passes through the through hole and the fixing assembly, the temperature measurement element abuts against the spring gasket, the spring gasket is arranged on the fixing box body, the fixing box body is clamped with the inner wall of the cylinder, the temperature transmitter is arranged in the fixing box body and is clamped with the inner wall of the cylinder, the temperature transmitter is respectively connected with the temperature measurement element and a data storage module, and the pressing cover is clamped with the cylinder and is attached to the temperature transmitter. According to the nuclear power station valve button type temperature acquisition device, through the cooperative design of the cylinder, the temperature measurement element, the spring gasket, the fixing box body, the temperature transmitter and the pressing cover, the problems that a nuclear power station cannot continuously detect the temperature of a detected valve, cannot collect the temperature data of the valve in time, is heavy in field installation workload, is inconvenient, and is low in safety are effectively solved.

Description

technical field [0001] The invention relates to the technical field of nuclear power plants, in particular to a button-type temperature acquisition device for nuclear power plant valves. Background technique [0002] At present, in the daily operation of nuclear power plants, many important valves need to measure the temperature, but the temperature measurement methods are still in the offline measurement technology stage, mainly using infrared imagers, infrared thermometers or installing thermocouples to measure the valves. Upstream and downstream temperature data. [0003] However, there are the following problems in using the off-line measurement method to collect the temperature of nuclear power plant valves: 1. Some discrete points of the temperature data collected in the off-line method cannot continuously monitor the valve temperature and track the trend of temperature parameters; 2. During the normal operation of the unit , the action time of the valve is not fixed,...
