回転軸とがずれるような心配がない。 Furthermore, a joint protrusion 34 is integrally formed on the outer surface of the other disc 29 of the rotor valve 27, which is a protrusion with a rectangular cross section extending in the diametrical direction. The joint protrusion 34 is slidably fitted into a groove 35a having a rectangular cross section formed in the free end of the rotary shaft 35, and transmits rotational force so as to rotate integrally with the rotary shaft 35. . Furthermore, when transmitting this rotational force, even if the rotational axis of the rotor valve 27 and the rotational axis of the rotational shaft 35 are slightly misaligned, they will slide between the joint protrusion 34 and the rectangular seal 34a. Since this error is absorbed, there is no fear that the rotation axes of the rotor valve 27 and the rotary shaft 35 will be misaligned due to processing errors during manufacturing.

１でシールする。 The rotary shaft 35 is fitted into a shaft hole 36a of a cylindrical bearing member 36 disposed in the central shaft portion of the flow passage housing 26.
The cylindrical bearing member 36 is inserted rotatably into the shaft 35 and sealed by two O-rings 37 and 38 respectively installed in two ring grooves provided in the shaft 35. Furthermore, as shown in FIG. 1, a cover member 40 is installed so as to enclose a flange 39 protruding from the shaft 35 and the end of the cylindrical bearing member 36, and an O-ring 4 is installed in the groove of the cylindrical bearing member 36.

も容易にできる。 Further, the device of this example has a rotor valve 27 portion,
Since the rotating shaft 35 part is constructed separately,
If damage such as cracking occurs in these parts, parts can be easily replaced or repaired. Also, the O-rings 37, 3 of the rotating shaft 35 are the most likely to wear out.
8 can also be easily replaced by removing the cover member 40 and pulling out the rotary shaft from the bearing member 36. Furthermore, it can be easily disassembled for maintenance.

防止できる。 In addition, since the rotor valve 27 and the rotating shaft 35 are connected by a joint protrusion and a rectangular groove that are slidably fitted into each other, machining accuracy is poor and mutual misalignment may occur. However, each rotor valve 27 must be rotated properly separately.
Since these are aligned by the pivot bearing portion 33, it is possible to prevent liquid leakage due to misalignment.

ことができる。 In addition, a cover member 40 is attached to the rotary shaft 35, and the cover member 40 is sealed with an O-ring 41, so that liquid leakage can be prevented even in the event of an emergency. Therefore, the improved sealing performance of the rotary shaft 35 portion improves the electrical insulation of the actuator 11 portion. Furthermore, by making the actuator 11 of resin, malfunctions due to rust can be prevented and the service life can be extended.

ある。 In addition, a cover member is attached to the rotary shaft and sealed with an O-ring, so that even in the unlikely event of liquid leakage, it is possible to prevent the cover member from leaking. Therefore, the improved sealing performance of the rotating shaft portion improves the electrical insulation of the actuator portion. Furthermore, by making the actuator made of resin, malfunctions due to rust can be prevented and the service life can be extended.

とする流路配管系の四方バルブ装置。[Claim for Utility Model Registration] A four-way valve device for a flow path piping system of an electrolyte circulation type battery, in which a rotor valve is pivoted into a circular chamber of a flow path casing having four flow path pipings. A rotary shaft is installed supported by a bearing part, the rotor valve is provided with a joint protrusion which is a small rectangular protrusion extending in the diametrical direction of the rotor valve, and the rotary shaft is inserted into a bearing member provided in the flow path casing. The joint protrusion is fitted into a groove, which is a rectangular groove bored in a connecting end of the bearing member, so as to be slidable in the longitudinal direction so as to be able to transmit rotational force, and the bearing member and the rotating shaft are connected to each other. an O-ring is disposed between the bearing member and the cover member, a cover member is disposed to cover a portion of the rotating shaft protruding from the bearing member, and an O-ring is disposed between the bearing member and the cover member.
1. A four-way valve device for a flow path piping system, characterized in that a ring is arranged and the rotary shaft is rotated by a resin actuator to switch the flow path.
