CONSTITUTION:For primary system sampling of a nuclear reactor, the female connector 32 is allowed to abut on a male connector 40 fitted to a sampling system 38 while the sample vessel 28 is held and after both connectors 32 and 40 are aligned to each other by operating the adjusting screw 64 of the turnbuckle 36, the female connector 32 is inserted into the male connector 40 at a stroke to link. Consequently, sampled water enters the female connector 32 through an automatic on-off valve and is recovered in the sample vessel 28. Then, when the operation lever 34 is drawn to pull the sample vessel 28 to an operator side, the female connector 32 and male connector 40 are disengaged from each other.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sample collection device installed in the primary thread nangle collection thread of a nuclear reactor, and particularly to a sample collection device installed in the primary thread nangle collection thread of a nuclear reactor. The purpose of the present invention is to provide a portable sample collection device that can collect samples under conditions of minimal atmospheric pressure and radiation exposure.

Radiation monitoring is carried out under various radiation control measures with the goal of ensuring the safety of radiation work.1 Measurement of the radioactivity level of the atmospheric gas in the containment vessel in the reactor coolant, and sampling to contribute to radiation exposure countermeasures. The system is one of them.

Conventionally, for example, a pigeon house is provided with a rounded vessel for collecting a portion of the fluid in the fluid passage, and the vessel is provided with pipe connectors configured as described above at both ends connecting with the nine passages. This allows the vessel to be configured to be detachable from the fluid passage. However, this pigeon house
Each pipe connector provided at both connection ends of the vessel [The vessel cannot be removed unless operated at the same time.]

Therefore, it is impossible to remove the vessel with one hand! #,
It is difficult to handle and difficult to handle.

Therefore, the applicant has developed a system that connects sleeves for attaching and detaching pipe connectors placed at both connecting ends of a vessel to a common operating rod, so that the attachment and detachment of the vessel can be performed simply by operating the operating lever with one hand. We have developed a pipe connector device that can easily carry out this process, and obtained the first patent (No. 7474). That is, FIGS. 1 and 2
In the figure, this tube connector device includes a female connector part 13 connected to both ends of a vessel 10, a female connector part 13 connected to a sample collection thread ljK, and a gold tip connected to both connector parts, respectively. Sleeves /l and -20 are provided which abut against each other under the action of coil springs /4' and 16, and a ball bearing here for locking both connector parts is provided inside one sleeve -〇, and the other sleeve /l is provided. The female connector part 13 is configured as a lock operation part that opens and closes the lock.
A locking operation of the pipe connector is performed on both connecting ends of the flow passage body which is detachably attached to a part of the fluid passage using a pipe connector provided with a ball valve λHiro on the other side of the pipe connector. The first connector part is arranged opposite to the connecting end of the fluid passage, and the lock operation part of the other connector part is connected by a common operation rod 26.

By the way, in the above-mentioned connector f2 &, when connecting the square connector part to the female connector part, if both ends of the female connector bend inward or outward and the gap between the two ends becomes misaligned, the female connector When connecting one side of both connectors to a female connector, even if one side of both connectors is connected, the other side is not connected in a mismatched state, which is not only inconvenient for the installation operation, but also
It is also dangerous as it may cause liquid leakage.

Therefore, as a result of further improved prototype production, the inventors have developed a connection mechanism that allows the sample vessel to be connected to the sample collection system in a one-touch manner. It has been found that it is possible to obtain a portable sample collection device that can be handled quickly and without leakage of sample water.
