Three air flow holes 33 are formed in the second mounting location 30, and each air flow hole 33 of the second mounting location 32 corresponds to one second vent hole of the second solenoid valve 20, i.e., each air flow hole 33 is butted against one second vent hole. Preferably, a second soft sealing rubber pad (not shown) is also arranged between each air flow hole 33 and the second vent hole.
In order to fix the first solenoid valve 10 to the base 30, threaded holes 42 are provided at two corners of a diagonal line of the first mounting position 40, and an internal thread is provided in each threaded hole 42. Two screws 11 and 12 are arranged at corresponding positions of the first electromagnetic valve 10, the two screws 11 and 12 penetrate through the first electromagnetic valve 10, and the lower end of the first electromagnetic valve is screwed into the threaded hole 42, so that the first electromagnetic valve 10 and the base 30 are fixed.
Similarly, screw holes 35 are provided at both corners of a diagonal line of the second mounting position 32, and an internal thread is provided in each screw hole 35. Two screws 21 and 22 are arranged at corresponding positions of the second electromagnetic valve 20, the two screws 21 and 22 pass through the second electromagnetic valve 20, and the lower end of the second electromagnetic valve is screwed into the threaded hole 35, so that the second electromagnetic valve 20 and the base 30 are fixed.
Of course, the first solenoid valve 10 and the second solenoid valve 20 may be fixed to the base 30 by rivets, welding, or adhesion.
A plurality of airflow passages are provided in the base 30, each of the airflow holes 41 is connected to one of the airflow passages, and each of the airflow holes 33 is also connected to one of the airflow passages. Of course, the air flow holes corresponding to the same solenoid valve are not connected to the same air flow channel.
A plurality of external air holes 45 are formed in the four side walls of the base 30, and each external air hole 45 is communicated with one air flow channel. And, a part of the external air holes 45 is connected to an external connector. In this embodiment, the external connector may be a bent external connector 50 or a straight external connector 51, one end of each external connector is connected to one external air hole 45, and the other end of each external connector may be connected to an air pipe and connected to an external device such as an air cylinder or a throttle valve through the air pipe.
Three operating states of the pneumatic circuit assembly are described below in conjunction with fig. 3-5.
Referring to fig. 3, when the first solenoid valve 10 and the second solenoid valve 20 are both de-energized, the air flow input by the air source 70 enters the pneumatic circuit assembly from the first ventilation hole 101 of the first solenoid valve 10, at this time, the first ventilation hole 101 is communicated with the first ventilation hole 104 of the first solenoid valve 10, and the air flow flows out from the first ventilation hole 104 and flows into the air cylinder 60 as an actuating element. A piston 63 is provided in the cylinder 60, and the piston 63 divides the cylinder into a first cylinder 61 and a second cylinder 62. The airflow output from the first ventilation hole 104 enters the second cylinder 62.
The air flow output from the first cylinder 61 flows into the first air passing hole 102 of the first solenoid valve 10, at this time, the first air passing hole 102 communicates with the first air passing hole 103 of the first solenoid valve 10, and the air flow flows from the first air passing hole 102 to the first air passing hole 103 and is finally discharged from one of the air flow holes on the base 30.
As can be seen from the air path in fig. 3, the air flowing out from the first vent hole 105 of the first solenoid valve 10 flows into the second vent hole 201 of the second solenoid valve 20 through the air flow channel in the base 30, but at this time, since the first vent hole 105 is not communicated with other vent holes of the first solenoid valve 10, no air flows out from the first vent hole 105, and therefore, no air flows into the second solenoid valve 20.
Referring to fig. 4, when the first solenoid valve 10 is powered and the second solenoid valve 20 remains in a power-off state, at this time, the first vent hole 101 of the first solenoid valve 10 communicates with the second vent hole 102, and the air flow input from the air source 70 enters the first solenoid valve 10 from the first vent hole 101 and is discharged from the first vent hole 102 and enters the first cylinder 61. The air discharged from the second cylinder 62 flows through the first air vent hole 104 into the first solenoid valve 10, and the air flow is discharged from the first air vent hole 105 because the first air vent hole 104 communicates with the first air vent hole 105.
Since the second solenoid valve 20 is still in the power-off state, the air flow flowing out from the first vent hole 105 of the first solenoid valve 10 flows into the second vent hole 201 of the second solenoid valve 20 through the air flow passage in the base 30, and at this time, the second vent hole 201 is communicated with the second vent hole 203, so that the air flow flows out from the second vent hole 203 to the muffler 69. In this state, the airflow velocity is fast because the airflow does not flow through the throttle valve 68.
Referring to fig. 5, when the first solenoid valve 10 is still in the energized state after the second solenoid valve 20 is also energized, the second vent hole 201 communicates with the second vent hole 202, and at this time, after the gas discharged from the first vent hole 105 of the first solenoid valve 10 enters the second solenoid valve 20 through the second vent hole 201, the gas is discharged from the second vent hole 202 and flows into the throttle valve 68. Since the air flow will pass the throttle valve 68 in this state, the speed of the air flow can be controlled.
It can be seen that a plurality of airflow channels are arranged in the base 30, the first electromagnetic valve 10 and the second electromagnetic valve 20 can be directly mounted on the base 30, and the first electromagnetic valve 10 and the second electromagnetic valve 20 are not communicated with each other through an air pipe, so that the problem that the volume of the pneumatic circuit assembly is too large due to the fact that a large number of air pipes are used can be avoided, and the difficulty that follow-up work is caused due to the fact that the air pipes are wound around each other can be avoided.
It should be noted that the above is only the preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto, and all the insubstantial modifications made by using the design concept of the present invention also fall within the protection scope of the present invention.
