切換制御する複合電磁切換弁に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composite electromagnetic switching valve that has two separate switching valve bodies operable by a pilot electromagnetic valve and switches and controls the flow direction of fluid.

つた。 Conventionally, this type of compound electromagnetic switching valve
As shown in Japanese Patent Publication No. 42799, the supply flow path and the load flow path of two switching valve bodies are connected in parallel, and as shown in Japanese Patent Publication No. 15129-1983, the supply flow path and the load flow path are connected in parallel. By connecting the flow path in series,
If the two switching valve bodies operate inconsistently, the two switching valve bodies connect the supply flow path, the load flow path, and the discharge flow path to each other to prevent malfunction of the fluid actuator connected to the load flow path. ing. However, although the former can switch and control a large flow rate of fluid during matching operation, the pressure fluid in the supply channel flows to the discharge channel during mismatching operation, and at the beginning of matching operation after mismatching operation, pressure increases on the supply channel side. It is not suitable for use in fluid equipment that has a small capacity pressure source as it tends to cause a rise delay, and the latter shuts off the supply flow path when the two switching valve bodies operate mismatched, resulting in consumption of pressure fluid on the supply flow path side. However, because the supply flow path and load flow path of the two switching valve bodies are connected in series, the fluid flow path inside the valve becomes longer and flow resistance increases, making it difficult for fluid systems to control large flow rates. It had drawbacks such as being unsuitable for use.

shows the de-energized state, and the two switching valve bodies 11A, 1
1B are connected in parallel in a circuit manner through communication passages 8, 9, and 10 of the sub-main body member 3. When the two pilot solenoid valves 14A and 14B are energized and operated simultaneously, the pilot fluid in the branch passage 15 is simultaneously introduced into each of the action chambers 17A and 17B, and the two switching valve bodies 11A and 11B respond to the action force of the pilot fluid. They are moved downwardly against the springs 12A, 12B, thereby respectively communicating the supply channels 4A, 4B and the load channels 5A, 5B and blocking the discharge channels 6A, 6B. The pressure fluid in the supply port P thus flows to the load port A through the communication passages 8 and 9 of the sub-body member 3 to actuate the fluid actuator. Furthermore, when the two pilot solenoid valves 14A, 14B are activated simultaneously from a energized state to a de-energized state, the two switching valve bodies 11A, 11B simultaneously lead out the pilot fluid in each of the working chambers 17A, 17B to the outside. The springs 12A and 12B actuate the upward movement to separately block the supply channels 4A and 4B, thereby communicating the load channels 5A and 5B with the discharge channels 6A and 6B. The fluid in the load port A thus flows through the communication passages 9 and 10 of the sub-body member 3 to the discharge port E to return and actuate the fluid actuator.

ユエータの誤作動を阻止することができる。 Next, the two pilot solenoid valves 14A, 14B
If one of the coils 22A, 22B breaks down due to burnout or the like and the two switching valve bodies 11A, 11B operate inconsistently, the two pilot solenoid valves 14A, 14B should be changed from the non-energized state shown in the figure. When electricity is applied and only the right pilot solenoid valve 14B operates, the switching valve body 11B is operated downward, communicating the supply flow path 4B and the load flow path 5B, and blocking the discharge flow path 6B, and the switching valve body 11A is activated. The load flow path 5A and the discharge flow path 6A are connected to each other in the illustrated position, and the supply flow path 4A is blocked. Communication path 9, load flow path 5A, and discharge flow path 6 of member 3
A. Since the flow flows to the discharge port E through the communication path 10 of the sub-body member 3, the pressure at the load port A communicating with the load flow path 5A does not rise to the pressure required to operate the fluid actuator, and the fluid actuator is in a stopped state. It remains as it is. Further, when the two pilot solenoid valves 14A and 14B are energized from the non-energized state shown in the figure and only the left pilot solenoid valve 14A is activated, the switching valve body 11A is operated downward and the supply flow path 4A is activated.
The switching valve body 11B is in the illustrated position without operating, and the load flow path 5B and the discharge flow path 6B are connected, and the supply flow path 4B is opened. The pressure fluid in the supply port P is blocked through the supply flow path 4B, the communication path 8 of the sub-body member 3,
The load flow path 5A flows to the discharge port E via the supply flow path 4A, the load flow path 5A, the communication path 9 of the sub-body member 3, the load flow path 5B, the discharge flow path 6B, and the communication path 10 of the sub-main body member 3. The pressure at the load port A communicating with the fluid does not rise to the pressure required to operate the fluid actuator, and the fluid actuator remains in a stopped state. Furthermore, two pilot solenoid valves 14A,
When 14B is de-energized from the energized state and only the right pilot solenoid valve 14B operates, the switching valve body 11B
is actuated upward by the spring 12B to shut off the supply flow path 4B and connect the load flow path 5B and the discharge flow path 6B, and the switching valve body 11A remains in the downward operation.
The fluid in the load port A flows to the discharge port E by the switching valve body 11B, and the fluid actuator returns to operation in the same manner as during the matching operation. Also, when the two pilot solenoid valves 14A and 14B are de-energized from the energized state and only the left pilot solenoid valve 14A operates,
The switching valve body 11A is moved upward by the spring 12A to block the supply flow path 4A and connect the load flow path 5A and the discharge flow path 6A, and the switching valve body 11B remains in the downward movement, but the switching valve body 11A is moved upwardly by the spring 12A. Load port A
The fluid flows to the discharge port E, and the fluid actuator returns to operation in the same manner as during the matching operation, thereby preventing malfunction of the liquid actuator.

できる。 Next, in order to change the supply passages 4A, 4B and the load passages 5A, 5B of the two switching valve bodies 11A, 11B into series communication, the sub body member 3 is replaced with the main body member as shown in FIG. Fitting hole 7A formed on the outer surface of 2
The main body member 25 is replaced with a sub-main body member 25 provided with a communication passage 23 that communicates the supply passage 4A with the load passage 5B of the fitting hole 7B and a communication passage 24 that communicates between the discharge passages 6A and 6B. You can change it accordingly.
According to this configuration, when the two pilot solenoid valves 14A, 14B are energized from a non-energized state and the two switching valve bodies 11A, 11B are aligned, the pressure fluid in the supply port P is transferred to the fitting hole 7B. From the supply flow path 4B to the load flow path 5B, the communication path 23 of the sub-body member 25,
It flows to the load port A via the supply flow path 4A and the load flow path 5A of the fitting hole 7A. In addition, from this state, when the two pilot solenoid valves 14A and 14B are de-energized and the two switching valve bodies 11A and 11B are aligned, the fluid in the load port A is discharged from the load flow path 5A of the fitting hole 7A. It flows to the discharge port E via the flow path 6A and the communication path 24 of the sub-main body member 25, and is switched and controlled. Then, when the two pilot solenoid valves 14A and 14B are energized from the de-energized state and only the pilot solenoid valve 14B is operated in a mismatched operation, the pressure fluid in the supply port P is transferred from the supply flow path 4B of the fitting hole 7B. The flow passes through the load flow path 5B and the communication path 23 of the sub-body member 25 to the supply flow path 4A of the fitting hole 7A, and the flow to the load flow path 5A is blocked by the switching valve body 11A. In addition, when the two pilot solenoid valves 14A and 14B are energized from a non-energized state and only the pilot solenoid valve 14A is activated, the pressure fluid in the supply port P flows to the supply flow path 4B of the fitting hole 7B. The flow to the load flow path 5B is blocked by the switching valve body 11B, and the fluid actuator remains in a stopped state. Next, 2
When the pilot solenoid valves 14A and 14B are de-energized from the energized state and only the pilot solenoid valve 14B is operated, the fluid in the load port A is transferred to the fitting hole 7A.
from the load flow path 5A to the supply flow path 4A, the communication path 23,
It flows to the discharge port E via the load flow path 5B, the discharge flow path 6B, and the communication path 24 of the fitting hole 7B. Furthermore, when the two pilot solenoid valves 14A and 14B are de-energized from the energized state and only the pilot solenoid valve 14A is operated, the fluid in the load port A is transferred from the load flow path 5A of the fitting hole 7A to the discharge flow path 6A. The fluid can flow through the passages 24 to the discharge ports E to prevent the fluid actuators connected to the load ports A from malfunctioning.
