is pressurized with helium gas, and the valve of refrigerant transfer pipe 4 (pulp)
After opening 5, liquid helium 3 is injected into the cryostat 7. FIG. 3 shows a conventional valve structure for a refrigerant transfer pipe having a vacuum insulation structure. Although the valve seat is fixed, the valve body is composed of a coil spring 12, a valve body nut 11, and a hole 22 through which liquid flows out. The valve body is tightened with a valve body seal nut 13 and sealed (sealed) with an O-ring 17, so that the valve and the atmosphere are sealed. To open this valve, turn the valve body seal nut (13) counterclockwise (direction C) to loosen the O-ring seal on the valve body, and the valve body will move up and down.

When turning 11 clockwise (direction B), coil spring 1
2 expands and the valve body 14 is also pushed, so the valve body 14 separates from the valve seat 15, so that the valve opens and liquid helium flows to the cryostat side. Once the valve is open, tighten the loosened valve body seal nut 13 to seal it and prevent helium from leaking. When closing the valve, by loosening the valve element seal nut 13 and tightening the valve element nut 11, the valve element comes into contact with the valve seat, so that the flow of liquid helium can be stopped. Liquid helium immerses the superconducting magnet 8,
When the liquid helium is collected at a suitable position Ai, the pulp (valve) 5 is closed to stop the injection of liquid helium.

に行なわなければならず、注入作業に拘束されやすい。Liquid helium is injected into the superconducting magnet by opening and closing the pressurizing pulp (valve) 9 and the pulp 5 of the refrigerant transfer pipe as necessary. Here, the opening and closing of the pressurizing pulp 9 can be automatically controlled using a solenoid valve, an electric valve, etc., but the pulp 5
Since this is not automated, the operator must always open and close the pulp 5, and is likely to be tied up in the pouring work.

伴う弁体の移動を自動的に行なえる。[Structure of the Invention] (Means for Solving If!1 Problem) Conventionally, a valve installed in a refrigerant transfer pipe needs to be moved when the valve body is separated from the valve seat (valve open) and when it comes in contact with the valve seat (valve closed). After loosening and tightening one valve body seal, which serves to prevent gas leaks, the pulp is opened and closed. Even if the opening and closing of the pulp, which was previously done manually, is performed by an electric motor using a transmission gear or a drive source such as compressed air, automatic control is required unless the manual operation of the valve seal nut that accompanies the opening and closing of the valve is performed automatically. It is not a valve. Therefore, if the expansion and contraction of the bellows is used to secure the valve body seal nut, the sealing performance of the valve body and the movement of the valve body as the valve opens and closes can be automatically achieved.

発揮される。(Function) By adopting an expandable bellows, there is no need to manually loosen or tighten the valve body seal nut each time the valve is opened or closed. This allows the nine automatic control valves to function using motors, high-pressure air, etc. as the driving source for opening and closing the valves.

流れ出る。17) The pulp is overflowing with the valve body Nara) IIK output gear 20 installed. The output gear 20 is connected to the motor pinion gear 19. Tokiha opens the pulp,
By rotating the pulp control motor 18,
Motor pinion gear 19 also rotates and is transmitted to output gear 20. Simultaneously with the rotation of the output gear, the valve element nut 11 also rotates in the opening direction (the direction in which the valve element and the valve seat are separated). The valve body moves down to D while pushing down the bellows 21 (shrinking) by the coil spring 12, and the valve opens. The coolant (for example, liquid helium) flows out through the holes 22 to the cryostat side.

When the output gear rotates, the valve element nut rises, and the spring coil that was pushing down the valve element contracts, causing the valve element to come into contact with the valve seat, closing the valve, and liquid helium (refrigerant) is released. The flow is closed.

業から開放された。As described above, according to the present invention, an automatic control valve for refrigerant having a vacuum insulation structure is constructed by absorbing the vertical movement or horizontal movement of the valve body due to opening and closing of the valve with the telescopic bellows. . This allows the refrigerant (liquid helium) to
It has become possible to automate the injection work, freeing people from injection work that can easily be tied up.
