[0026] like Figure 1 、 Figure 2As shown, the first aspect of the embodiment of the present application provides an air circuit board integrated module, including a substrate, a first cover plate, a second cover plate, a distribution valve and a plurality of control valves, a cavity is formed on the substrate, and a plurality of air grooves are provided on the front and back of the substrate; the first cover plate is provided on the front of the substrate, and the second cover plate is provided on the back of the substrate; the distribution valve and the control valve are both installed on the first cover plate, the distribution valve is connected to the cavity, and one or more control valves can be selectively connected through the air groove.

[0027] In the embodiment of the present application, the material of the substrate is aluminum alloy, which is the same as the material of the currently used air circuit plate. The material of the first cover plate and the second cover plate is also aluminum alloy. The volume of the cavity on the substrate is equivalent to the volume of the air cylinder in the existing brake cabinet, so that it can be used to replace the air cylinder. The air groove is formed on the substrate, and the air groove is set according to the position of the control valve and the cavity, so as to connect the cavity and the control valve and supply air to the control valve. The first cover plate and the second cover plate are respectively covered on the front and back of the substrate to ensure the sealing of the air circuit plate. The distribution valve and the control valve are both installed on the first cover plate, and the distribution valve is connected to the cavity. External gas enters the substrate, and is passed into the distribution valve through the air groove, and then enters the cavity through the distribution valve. The distribution valve can be selectively connected to the control valve through the air groove to supply air to the control valve according to actual needs.

[0028] The air manifold integrated module of the present embodiment has a cavity provided on the base plate of the air manifold. The base plate is brazed to a first cover plate and a second cover plate to form a single unit. A distribution valve and a control valve are mounted on the first cover plate on the front of the base plate, along with multiple air slots. The distribution valve communicates with the cavity. Under the control of the distribution valve, one or more control valves communicate with the cavity, which serves as a replacement for the existing air cylinder. This air manifold integrated module eliminates the external air cylinder and piping structure, replacing the air cylinder with a cavity on the base plate. Air is supplied to the control valve via the air slots on the base plate, saving space in the brake cabinet and reducing manufacturing and maintenance costs.

[0029] In order to ensure basic connection and sealing between the first cover plate and the second cover plate, the first cover plate and the second cover plate are respectively connected to the base plate by brazing.

[0030] Furthermore, in order to satisfy the role of the cavity in replacing the cylinder, the volume of the cavity is 0.5 L to 0.7 L. In order to supply air more smoothly, the depth of the air groove is 10 mm to 26 mm and the width is 8 mm to 18 mm.

[0031] In some embodiments, the air circuit board integrated module further includes an air intake pipe, which is mounted on the second cover plate, and the air intake pipe is connected to an air groove and is connected to the distribution valve through the air groove. In the embodiment of the present application, the air intake pipe is a train pipe, which delivers dry air from the outside into the air circuit board integrated module. The air intake pipe is mounted on the second cover plate on the back of the substrate, and is separately arranged from the distribution valve and the control valve on the first cover plate on the front to avoid mutual interference. The gas entering the substrate through the air intake pipe is transported to the distribution valve through the air groove, and then transported to the cavity by the distribution valve, and distributed to each control valve as needed by the distribution valve. Furthermore, the air circuit board integrated module includes a filter, and a filter is arranged between the local reduction chamber and the cavity. The distribution valve is provided with a filter, and the air is filtered after passing through the distribution valve to ensure that there are fewer impurities in the air entering the cavity. Furthermore, the local reduction chamber of the distribution valve is connected to the cavity.

[0032] A second aspect of the present invention provides a brake cabinet comprising a cabinet body and the aforementioned integrated pneumatic manifold module, which is mounted on the cabinet body. The brake cabinet of the present invention differs from conventional brake cabinets in that the integrated pneumatic manifold module is mounted on the cabinet body, rather than on conventional pneumatic manifolds. The integrated pneumatic manifold module saves space in the brake cabinet and reduces manufacturing and maintenance costs.

[0033] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
