とがある。In the above explanation of the function of the ball valve, the ball (10
) rotates from the state shown in FIG. 3(d>) to the state shown in FIG. The fluid remains in the ball (10), and the ball (10) is in the state shown in FIG.
When the state shown in the figure is reached, the liquid remaining in the cavity (20) is removed from each channel (7), (8), (9) and the T-shaped channel (
14) is completely isolated from the internal fluid flow. Especially when used in the food industry, chemical and pharmaceutical industry,
The fluid is foodstuffs, chemicals, etc., and as mentioned above, the fluid is
20) When a fluid is isolated, it may become spoiled or degraded. In order to remove such rotten or altered fluid from the cavity (20), it is necessary to disassemble and clean it. However, if the above-mentioned ball valve is disassembled and cleaned while connected to the fluid conveying pipe, rotten or deteriorated fluid will leak into the pipes (5), (7), (8), and (9), causing external damage. There is a risk that it may get mixed into the fluid in the fluid conveyance path. Therefore, the ball valve must be removed from the fluid conveyance path and then disassembled for cleaning. Regarding the assembly work after the disassembly and cleaning described above, if the contact pressure between the ball (10) and the valve seat ring (11) (12) (13) is not adjusted to the specified value, the rotation of the ball (10) will not occur. Also, the ball (10)
A leak has occurred between the valve seat ring (11), (12), and (13), and the connections (9), (8), and (7) are not connected in the respective states of Fig. 3 (b) to (d). Fluid may leak into each.

B) (3'a) Corresponds to (40). Figure 6 (
In a), the flow channels (3B), (39), and (40) in three directions are all open and can communicate with each other. Fig. 6 (b)
In this case, the flow path (38) is closed and the flow path (39) and the flow path (
40) are in communication with each other, and in FIG. 6(C), the channel (39) is closed, and the channel (38) and the channel (40) are in communication with each other, and in FIG. 6(d) In this case, the flow path (40) is closed and the flow path (38) and the flow path (39) are in communication with each other. The above-mentioned flow paths (38), (39), and (40) are closed by the rotation of the surface cam (44), and the valve stem (46) is closed.
) comes into contact with the surface cam (44) and is pushed down against the elastic force of the spring (51), causing the valve body (48
) is brought into close contact with the bottom surface (41a') of the valve chamber (41), and the contact pressure against the bottom surface (41a') of the valve chamber (41) is applied mechanically or forcefully due to the surface angle (10). When manufacturing the cam type valve, it is set in advance to a value sufficient for the fluid pressure. In addition, each flow path (38) (39) (40)
is opened by rotating the surface cam (44) to open the rift 1 part (4) of the surface cam (44) shown in FIGS. 6(a) to 6(d).
4B) coincides with the position of the valve stem (46) corresponding to the flow path to be opened, the valve stem (46) is pressed against the spring (51).
Due to the elastic force of , the surface cam (44) is raised by the lift dimension (h). That is, by ensuring that the valve body (48) is above the bottom surface (,lla) of the valve chamber (41) by the lift dimension (h), each flow path (38) (39) (40
) is released.

Effects of the Invention - Lm As invented, the cam type valve of the present invention can reliably close and open the flow path using the surface cam, so that the fluid flowing in the flow path does not leak and the fluid flow is controlled. can be controlled accurately. In addition, since the bottom of the valve chamber is flat, fluid does not remain inside the valve chamber, and the valve body is easy to assemble in parts.
Since there are no maintenance points (11), it can be disassembled and cleaned. From the above, it can be said that the +i construction is optimal as a sanitary valve used in the food industry, etc.

尚、本発明のカム式バルブは、前記の三方向に流路を有

れるものではない。The cam type valve of the present invention is not limited to the type having flow passages in three directions as described above, but may be of the type having flow passages in two directions, and the shape of the surface cam is also not limited to the above-described type. It is not something that will be done.

更に本発明は、上記サニタリーバルブとしての用途に限
らず、広く一般的な用途に通用可能である。Furthermore, the present invention is applicable not only to the above-mentioned sanitary valve but also to a wide range of general uses.
