This is known from Japanese Patent Laid-open No. 84 or Japanese Patent Application Laid-open No. 55-97206, and is simplified and explained with reference to FIG. 2 as follows. That is, FIG. 2 is a view of the rotary valve 1 cut on the rotary shaft, and the rotary valve 1 consists of a rotor 30 and a fixed plate 61, and the rotor 60 has an annular groove 62 centered on the rotary shaft. A communication portion 63 is formed that can communicate with the aperture 34 of the stationary platen. Here, the opening 64
Alternatively, 65 is a part of a plurality of arrays arranged at regular intervals on the same circumference centered on the rotation axis of the fixed plate 61,
Connecting pipes 18 to 25 described in FIG. 1 are connected here. Furthermore, the stationary platen 31 has an opening: '1°66 for supplying or extracting fluid. Even when the rotor 30 rotates through a certain angle, the aperture 36 always forms a passage with another aperture of the same type as the aperture 34. Further, the annular groove 62 in the rotor 3o may be located at the center of the rotating shaft, in which case the aperture 37
, the communication portion 38 and the passage such as the opening portion 65 are formed.
上記公知の回転弁をすでに説明した擬似移動床による吸
着分離装置の流体の供給および抜き出し用として使用し
ようとするとき必然的にそれぞれ別個の複数の同心環状
溝が必要となる。If the known rotary valve is to be used for supplying and withdrawing fluid from the previously described adsorptive separation device with a simulated moving bed, a plurality of separate concentric annular grooves are necessarily required.

流体の圧力も大きなものとなる。さらに、環状溝の増加

転弁内での流体の気密を保つためにはぼり大な力で回転
子と固定盤を密着せねばならない。このことは回転弁の
設計が複雑となり製作費用がかさみ、かつ流体の洩れに
対する不安も大きなものとなる。Generally, adsorption separation using a simulated moving bed requires a large number of adsorption chambers, and as a result, the pressure drop of the fluid passing through the adsorption chambers becomes large. Therefore, the pressure of the fluid flowing through the annular groove within the rotary valve also becomes large. Furthermore, as the annular groove increases, the contact area between the rotor and the stationary plate increases, and in order to maintain airtightness of the fluid within the rotary valve, the rotor and stationary plate must be brought into close contact with each other with great force. This complicates the design of the rotary valve, increases manufacturing costs, and increases concerns about fluid leakage.
そこで、本発明者等は上記欠点を克服すべく該回転弁に
関し鋭意研究した結果、本発明に到達した。Therefore, the inventors of the present invention conducted intensive research on the rotary valve in order to overcome the above-mentioned drawbacks, and as a result, they arrived at the present invention.
すなわち、本発明は、′流体の通過する通路をもつ回転
弁であって、該回転弁内の通路の一部を備えた複数の固
定盤の間に、通路切替え川の回転子を回転自在に配設し
たことを特徴とする。That is, the present invention provides a rotary valve having a passage through which fluid passes, in which a passage switching rotor is rotatably placed between a plurality of fixed plates each having a part of the passage in the rotary valve. It is characterized by having been placed.
上記本発明によれば、二つの固定盤の間に回転子を設け
たために、従来、回転子と固定盤との一つの接触面に設
けられていた複数の同心環状溝を二つの接触面に分割す
ることができる。According to the present invention, since the rotor is provided between the two fixed plates, the plurality of concentric annular grooves that were conventionally provided on one contact surface between the rotor and the fixed plate are replaced with two contact surfaces. Can be divided.
このため、一つの接触面に設置される同心環状溝の数が
減少し、かつ、その分、接触面積も減少できるので、回
転弁内の流体の気密を保つために回転子と固定盤に加え

になり、回転子の径が％になったとすれば総圧力は従来
のハで良いことになり、回転弁の設計が非常に容易とな
る。また、回転弁内での流体の洩れに対する不安も解消
できる。For this reason, the number of concentric annular grooves installed on one contact surface is reduced, and the contact area is also reduced accordingly. The total pressure applied can be significantly reduced. Also,
The pressure to be applied from the outside is approximately equal to the pressure of the fluid in the annular groove.
Since the value is the pressure multiplied by the contact area, the number of annular grooves is %
If the diameter of the rotor is reduced to %, the total pressure can be kept at the conventional value of C, which greatly simplifies the design of the rotary valve. Furthermore, concerns about fluid leakage within the rotary valve can be eliminated.

で回転子および／または固定盤をつくってもよい。Although the material of the rotary valve according to the present invention is not limited to the present invention, it is preferable that the rotor itself or the contact surface of the rotor be made of a material that has self-lubricating properties. Suitable materials include, for example, Teflon, Teflon-impregnated glass cotton, fluorinated graphite, polyacetal resin, polyamideimide resin, or even nylon or polyester resin. Furthermore, the rotor and/or stationary plate may be made of ceramics.

回転弁を含むことはいうまでもない。Furthermore, a rotary valve as shown in Japanese Patent Application Laid-Open No. 55-972011 (related to the invention previously proposed by the present inventors)
It goes without saying that the present invention also includes these rotary valves.
上記のように、本発明は回転弁内の通路の一部を備えた
複数の固定盤の間に、通路切替え用の回転子を回転自在

計が非常に容易になり、かつ弁内での流体の洩れに対す
る不安も解消できる。また、回転子両サイドの圧力がバ
ランスし、シールも容易となる。As described above, the present invention has a rotor for switching passages rotatably provided between a plurality of fixed plates each having a portion of passages in a rotary valve. The resulting plurality of concentric annular grooves can be divided into two contact surfaces, making it possible to reduce the total pressure required to bring the rotor and stationary plate into close contact. Therefore, the rotary valve can be designed very easily, and concerns about fluid leakage within the valve can be eliminated. Additionally, the pressure on both sides of the rotor is balanced, making sealing easier.
