Description

Technical Field

[0001] The present application relates to the field of valve technology, and in particular to a plate-type solenoid valve assembly. Background Art

[0002] The plate-type solenoid valve is formed by setting an air channel on the base to form an air circuit plate, and then installing the plate-type valve on the air circuit plate to realize the function of the solenoid valve group.

After the existing air circuit plate is manufactured, the valve position set on it is fixed and cannot be expanded. If the valve position needs to be increased later, the air circuit plate can only be replaced as a whole, or expanded through external piping, resulting in poor expansion capabilities.

[0031] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0032] See also Figure 1-Figure 5 The present application provides a plate-type solenoid valve assembly, including an air circuit board 10. The air circuit boards 10 are provided with at least two of them. Each of the air circuit boards 10 is provided with a screw hole communicating with the internal air circuit. A plate-type valve 20 is movably provided on the air circuit board 10. A solenoid 30 is screwed into the corresponding screw hole. A plug tube 40 is inserted into the two solenoids 30. The two air circuit boards 10 are connected via the plug tube 40. The solenoid 30 is screwed into the corresponding screw holes of the two air circuit boards 10, thereby providing a sealing condition for the plug tube 40. The two air circuit boards 10 are then joined together, with the plug tube 40 inserted into the solenoid 30 at both ends. This allows the two air circuit boards 10 to communicate with each other, thus achieving expansion. The connection structure is simple, easy to operate, and convenient for modifying existing air circuit boards 10.

[0033] See also Figure 2-Figure 5 The end face of the screw tube 30 is provided with a notch. Wrap raw tape around the thread of the screw tube 30, and the notch is used for an external screwdriver or other tool to screw the screw tube 30 into the screw hole, so that the end of the screw tube 30 is flush with the end face of the screw hole so that the two air 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 between the plug tube 40 and the inner wall of the spiral tube 30.

[0035] See also Figure 1The two gas manifold plates 10 are fastened together by means of fasteners. Long screws pass through the expanded gas manifold plate 10 and are screwed to the original gas manifold plate 10 to achieve the connection between the two gas manifold plates 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 provided on the empty valve position of the gas circuit board 10. The empty valve position needs to be sealed with the cover plate 60, and the cover plate 60 is also fixed to the corresponding empty valve position by conventional screws.

[0038] See also Figure 1-Figure 2 A card slot is provided under the gas circuit board 10. The card slot is used to install the guide rail mounting piece, and the guide rail mounting piece 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 block the valve hole corresponding to the empty valve position.

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

[0041] See also Figure 1 A quick-connect connector 90 is threadedly connected to the corresponding screw hole on the gas circuit board 10. The quick-connect connector 90 is used to connect to the external air pipe for easy connection of the external pipeline.

[0042] The working principle of the plate-type solenoid valve group is as follows: the side of the gas circuit board 10 is usually provided with screw holes that are compatible with the plug 70, quick-plug connector 90, etc. When the original gas circuit board 10 is expanded, the plug 70, quick-plug connector 90 and other components on the side are removed, and the external thread of the screw tube 30 is wrapped with raw tape. Then, the screw tube 30 is screwed into the screw hole using a screwdriver or other tool. 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, 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 board 10 in the same way, and then the two gas circuit boards 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 of the side surface is required to be higher, while the connection method of the plug tube 40 is adopted, which will not be affected by the roughness of the side surface of the air circuit plate 10 and ensure air tightness. In summary, the screw tube 30 is screwed into the corresponding screw holes of the two air circuit plates 10 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 expansion is achieved. The connection structure is simple, easy to operate, and convenient for modifying the existing air circuit plates 10.
