The screw tube 30 is screwed in the corresponding screw holes of the two gas circuit boards 10 to provide sealing conditions for the plug tube 40, and then the two gas circuit boards 10 are fitted and connected, so that the plug tube 40 is inserted into the screw tubes 30 at both ends, so that the two gas circuit boards 10 are connected, and expansion is achieved. The connection structure is simple, easy to operate, and convenient for modifying the existing gas circuit boards 10.

[0033] See also Figure 2-Figure 5 The end face of the screw tube 30 is provided with a notch. The thread of the screw tube 30 is wrapped with raw tape, and the notch is used for an external screwdriver or other tool to screw the screw tube 30 into the screw hole, and the end of the screw tube 30 is flush with the end face of the screw hole so that the two gas circuit boards 10 fit together.

[0034] See also Figure 2-Figure 5 , sealing rings 50 are provided at both ends of the plug tube 40. The sealing rings 50 are used to improve the sealing performance of the plug tube 40 and the inner wall of the spiral tube 30.

[0035] See also Figure 1The two gas circuit boards 10 are connected together by fasteners. Long screws pass through the expanded gas circuit board 10 and are screwed to the original gas circuit board 10 to achieve the connection between the two gas circuit boards 10.

[0036] See also Figure 1 The plate valve 20 is connected to the gas circuit board 10 by means of fasteners. The plate valve 20 is also fixed to the valve position of the gas circuit board 10 by means of conventional screws.

[0037] See also Figure 1 , a cover plate 60 is arranged on the empty valve position of the gas circuit board 10. The empty valve position needs to be blocked by the cover plate 60, and the cover plate 60 is also fixed on the corresponding empty valve position by conventional screws.

[0038] See also Figure 1-Figure 2 A card slot is provided below the gas circuit board 10. The card slot is used to install the guide rail mounting member, and the guide rail mounting member is used to be installed on the guide rail for installation and fixation of the entire solenoid valve group.

[0039] See also Figure 1 A plug 70 is screwed into the corresponding screw hole on the gas circuit board 10. Each valve position has a corresponding screw hole, and the plug 70 is used to plug the valve hole corresponding to the empty valve position.

[0040] See also Figure 1 , a muffler 80 is threadedly connected in the corresponding screw hole on the gas circuit board 10. The entire solenoid valve group exhausts gas during operation, and the gas is discharged through the muffler 80 here to reduce exhaust noise.

[0042] The working principle of the plate-type solenoid valve group is as follows: the side of the gas circuit plate 10 is usually provided with screw holes that are compatible with the plug 70, the quick-plug connector 90, etc. When the original gas circuit plate 10 is expanded, the plug 70, the quick-plug connector 90 and other components on the side are removed, the external thread of the screw tube 30 is wrapped with raw tape, and then the screw tube 30 is screwed into the screw hole using a screwdriver or other tools. The end of the screw tube 30 is flush with the end face of the screw hole so that the two gas circuit plates 10 fit together, and then the sealing ring 50 is put on both ends of the plug tube 40, and then one end of the plug tube 40 is inserted into one of the screw tubes 30. On the other hand, the other screw tube 30 is installed on the expanded gas circuit plate 10 in the same way, and then the two gas circuit plates 10 are merged so that one plug tube 40 is inserted into the screw tubes 30 on both sides at the same time, and finally the long screw is passed through the expanded air circuit plate 10 and screwed to the original air circuit plate 10. It should be noted that if the side sealing method of the air circuit plate 10 is adopted, the roughness requirement of the side is relatively high, and the connection method of the plug tube 40 is not affected by the roughness of the side of the air circuit plate 10, so as to ensure the air tightness. In summary, the screw tube 30 is screwed into the corresponding screw holes of the two air circuit plates 10, so as to provide sealing conditions for the plug tube 40, and then the two air circuit plates 10 are fitted and connected, so that the plug tube 40 is inserted into the screw tubes 30 at both ends, so that the two air circuit plates 10 are connected, and the expansion is realized. The connection structure is simple, easy to operate, and it is also convenient to modify the existing air circuit plate 10.
