Radioactive gas sampling equipment capable of realizing self-adaptive connection

Abstract

The invention relates to radioactive gas sampling equipment capable of realizing self-adaptive connection. The equipment comprises an outer box, a sampling steel cylinder and two second cylinder bodies; a supporting seat is arranged at the bottom in the outer box through a trigger assembly; first cylinder bodies are oppositely arranged on the two sides in the outer box; first pistons are arranged in the first cylinder bodies; piston rods are arranged on the first pistons; the ends of the piston rods penetrate out of the first cylinder bodies and are provided with male connectors; the sampling steel cylinder is placed on the supporting seat; female connectors are oppositely arranged at the two ends of the sampling steel cylinder; the two second cylinder bodies are arranged on the top in the outer box and communicated with the two first cylinder bodies respectively; second pistons are arranged in the second cylinder bodies; first sliding rods are arranged on the second pistons; and the first sliding rods penetrate through the top of the outer box and are connected with a self-adaptive driving mechanism arranged on the top of the outer box. In the prior art, sampling equipment needs to be manually connected with a plurality of pipe connectors in the sampling process, and a plurality of valves need to be manually opened and closed, as a result, the operation process is tedious, time and labor are wasted, and the sampling efficiency is low. With the radioactive gas sampling equipment capable of realizing self-adaptive connection adopted, the above problems can be solved.

Description

technical field [0001] The invention belongs to the technical field of sampling equipment, in particular to a self-adaptive joint radioactive gas sampling equipment. Background technique [0002] The nuclear island of a nuclear power plant is equipped with core cooling pipes, and the coolant in the cooling pipes is easily decomposed into hydrogen and oxygen (2H 2 0→2H 2 +O 2 ), excessive oxygen is likely to promote oxidation and corrosion of cooling pipes, and it is easy to react with hydrogen to cause an explosion. Therefore, hydrogen is added to the cooling pipes to inhibit the occurrence of decomposition reactions, thereby reducing the amount of oxygen generated. However, in order to avoid excessive accumulation of oxygen, chemists need to regularly test the hydrogen and oxygen content of the radioactive gas in the cooling pipeline to ensure safe operation. [0003] At present, the sampling equipment in the prior art mainly includes an air intake pipe, a sampling cylin...
