れるようになつている。 FIG. 2 shows details of the switching device X provided in the injection machine. Reference numeral 10 denotes a valve body, in which inlet ports 11, 12, and 13 are formed on one side, and a discharge port 14 is formed on the other side. A spool 16 is housed in a valve chamber 15 formed in the valve body 10 so as to be movable in the axial direction. The spool 16 has a through hole 17 passing therethrough and a through hole 19 that is closed by a blind plug 18 . Further, a protection tube 22 and a positioning guide tube 23 are integrally fixed to the valve body 10 via blocks 20 and 21. Setting holes 24, 25, 26 are formed in the upper surface of the positioning guide tube 23, and a long hole 2 is formed in the lower part.
7 is formed. Further, a through hole 28 is formed on the base side of the spool 16. A block 29 having an insertion hole 29a is fixed to the base end of the spool 16 with a stop bolt 30. The retaining bolt 30 also functions as a blind plug that closes the discharge hole 28. 31 and 32 are annular sealing bodies. Reference numeral 33 denotes a rotation prevention rod for preventing rotation of the spool 16 in the circumferential direction and aligning the flow paths accurately, and is integrated with the block 29 and guided in the elongated hole 27. Reference numeral 34 denotes a positioning rod, which is inserted into the insertion hole 29a from the setting holes 24, 25, and 26.

At the time of switching, the positioning rod 34 is pulled out, the rotation preventing rod 33 is gripped and the spool 16 is moved one step forward, and then the positioning rod 34 is dropped from the setting hole 25 into the insertion hole 29a. As a result, the inlet 1 is inserted through the through hole 17.
The fluid from 2 escapes to the outlet 14. Furthermore, if you move to the next step in the same way, the through hole 2
Fluid from the inlet 11 can be communicated to the outlet 14 via the inlet 8 . In this manner, by moving the spool 16, different types of fluids can be directed and switched and fed into a common flow path.

At this time, the oil 44 is compressed via the diaphragm 43 in accordance with the fluid pressure, and the pressure value is displayed on the pressure gauge 42. When the spool 16 is moved to the next step, the inlet 1
The fluid from 2 passes through the through hole 39, the through hole 19, the communication hole 37, and the guide hole 35 in this order, and is discharged from the discharge port 14. When the fluid is further moved to the next step, the through hole 28 coincides with the communication hole 36, and the fluid that has been fed so far is discharged from the through hole 36, and the remaining fluid that has been introduced from the inlet 12 and whose pressure feeding has been stopped is discharged from the through hole 36. The fluid passes through the through hole 38, the through hole 19, the through hole 39, and the communication hole 45 in this order and is discharged from the inlet 13.

場合の早急な対処などの点から特に有効である。 As described above, the present invention has a structure in which switching is performed by moving the spool instead of the conventional valve operation, so that erroneous switching operations can be prevented and the operation can be performed quickly and reliably. If only chemicals with the same properties are to be changed, switching with a valve is not a problem, but depending on the construction stage, different types of fluids such as bentonite or air, which can cause the deposition of particles other than the chemical, may be changed many times. This is particularly effective when adopting an injection method that performs the following steps, from the viewpoint of accurate switching of flow paths and prompt response in the event of trouble.

る。 On the other hand, in the present invention, a plurality of setting holes are formed in the guide tube, and the positioning rod is inserted into the spool through these setting holes to achieve axial positioning. By moving the anti-rotation rod integrated with the spool along the spool, positioning in the circumferential direction is achieved.The spool can be accurately moved to the desired position to connect the inlet and outlet of the valve body. Communication can be ensured.
