る動作が繰返される。 Therefore, when pressure is applied to the reaction vessel, the diaphragm 7
Then, by operating the cylinder 8, a gas pressure approximately equal to the internal gas pressure of the reaction vessel is applied to the pressure equalization chamber 9, and the connecting pipe 2
Since the pressure is applied to the inside of the box 21 through the box 7 and is balanced with the internal gas pressure, the internal gas will not leak from the seal portion 3. When the gas (air) from the pressure equalization chamber 9 leaks to the outside from the seal part 3, the pressure inside the pressure equalization chamber 9 fluctuates and the balance with the internal gas is broken, causing the cylinder 8 to rise through the diaphragm 7 and its upper end. Since the lower end 16' of the needle valve 16 is lifted at the center part 8' and the valve 13 is opened, the pressurized gas (air) in the pressurizing cylinder 12 enters the pressure equalizing chamber 9, and the gas pressure in the same chamber 9 is changed to the above-mentioned internal gas pressure. The operation of lowering the diaphragm 7 and closing the valve 13 in this state is repeated.

節するものである。 Furthermore, when the reaction vessel is brought into a reduced pressure (vacuum) state, the diaphragm 7 and cylinder body 8 operate, and the pressure equalization chamber 9 is brought into a reduced pressure state approximately equal to the internal gas pressure of the reaction vessel.Of course, the pressure inside the box 21 is also reduced, Since the pressure of the lubricating oil inside is also reduced, the lubricating oil will not flow into the reaction vessel. Then, when the pressure of the internal gas in the reaction vessel increases slightly, the diaphragm 7 and the cylinder 8 rise as described above, and accordingly the valve 13 opens to slightly increase the gas pressure in the pressure equalization chamber 9 and bring it into equilibrium with the internal gas. The operation of lowering the diaphragm 7 and the cylinder 8 to close the valve 13 is repeated. Also, a diaphragm 7 is used to control the pressure inside the pressure equalization chamber 9.
The pressure caused by the tension of the diaphragm 7 is adjusted by rotating the pressurizing tube 12 containing the pressure of the diaphragm 7 to adjust the screwing of the threaded part 11 and adjusting the position of the ceiling 10.

易い欠陥があつた。 Conventional seal leakage prevention devices prevent grease leakage by measuring the equal pressure between the internal gas of the reaction vessel and the grease in the rotary shaft seal box. There was a defect that the grease easily leaked into the reaction vessel under reduced pressure).
本案は上記欠陥に鑑みなされたものであつて本

洩を防止することができる。 The present invention was developed in view of the above-mentioned defects, and since the present invention is constructed as described above, the gas (air) within the seal portion 3 of the rotating shaft 2 is in equilibrium with the reduced gas pressure within the reaction vessel, and the inside of the seal portion 3 is balanced. The lubricating oil can also be balanced with the internal gas in a reduced pressure state, thereby preventing the lubricating oil from leaking into the reduced pressure reactor.
