[0019] Reference Figures 1 to 4 As shown, this utility model provides a multi-specification interface conversion device for a brake valve body, including: a brake valve body 1, and a fixing seat 11 provided at the lower end of the brake valve body 1.
[0020] The brake valve body 1 has a first valve port 12 and a second valve port 14 on its left and right sides. The surface of the brake valve body 1 is symmetrically fixed with a semi-ring plate 1 2 and a semi-ring plate 21. The right side of the semi-ring plate 1 is movably connected to a rotating disk 4 via a rotating column 41. The surface of the rotating disk 4 is sleeved with a conversion joint 3 through a connecting slot 42. A mating plate 31 is welded to one side of the conversion joint 3, and a flange 32 is welded to the other side of the conversion joint 3. The side of the mating plate 31 is sealed and pressed against the valve surface of the second valve port 14 by a sealing gasket 33. The surface of the mating plate 31 is fixedly screwed to the end face of the second valve port 14 by a limiting anti-detachment column 5.
[0021] First, the multi-specification interface conversion device is installed on the surface of the brake valve body 1 using semi-ring plate 1 2 and semi-ring plate 21. When connecting pipes of different specifications, the conversion connector 3, which matches the specification of the external pipe joint, is rotated and placed on the surface of the brake valve body 1. The mating plate 31 of the current conversion connector 3 is pushed to press and fit against the interface of the brake valve body 1, and the nut is screwed into the limit anti-disengagement column 5 to fix the interface of the brake valve body 1 and the current conversion connector 3. Then, the external pipe is screwed into the flange 32 of the current conversion connector 3, thus completing the connection and installation of external pipe joints of different specifications and the brake valve body 1.
[0022] In this embodiment, an exhaust valve port 13 is provided at the front end of the brake valve body 1. Semi-ring plate 1 2 and semi-ring plate 21 are fixed to the brake valve body 1 by fastening bolts 22. The rotating disk 4 has four sets of equidistant connecting slots 42 on its circumference; each connecting slot 42 is fitted with a corresponding adapter 3. A rotating column 41 is welded to the center of the left end face of the rotating disk 4, and three sets of limiting anti-detachment columns 5 are connected around the outside of each connecting slot 42. The flange 32 on the right side of the adapter 3 has mounting holes 35; and the flange 32 is connected to the air source pipeline. A flange gasket 34 is snapped onto the flange 32.
[0023] In a preferred embodiment, the brake valve body 1 is connected to an external air source pipeline via a first valve port 12 and a second valve port 14. Semi-annular plates 21 and 21 are used to mount the rotating disk 4 and the adapter 3 on the surface of the brake valve body 1. By rotating the rotating disk 4, the matching adapter 3 on the rotating disk 4 is positioned on the side of the valve port, enabling the conversion and connection of multiple specifications of the brake valve body 1's interfaces. This facilitates efficient and convenient conversion of brake valves and pipelines with inconsistent interfaces, shortens the installation time for disassembling and replacing adapters, and simultaneously integrates various different specifications of the brake valve body's interfaces. The flange 32 on the right side of the adapter 3 is used for connecting an external pipeline with the same interface specifications.
[0024] In this embodiment, the limiting anti-detachment column 5 is composed of a connecting column section 51, a limiting column section 52, and an externally threaded column section 53. The connecting column section 51 is located through the rotating disk 4. The side end of the connecting column section 51 is connected to the docking disk 31 through the limiting column section 52, and the surface of the externally threaded column section 53 is screwed to the end face of the second valve port 14 through a nut.
[0025] As a preferred implementation, the limiting anti-detachment column 5 limits the connection between the rotating disk 4 and the mating disk 31 through the connecting column section 51 and the limiting column section 52, so that the external thread column section 53 and the nut screw the mating disk 31 of the conversion joint 3 to the valve port of the brake valve body 1, ensuring that the multiple sets of conversion joints 3 are tightly and firmly installed with the valve port of the brake valve body 1.
[0026] This utility model's multi-specification interface conversion device for brake valve bodies effectively solves the problem that existing brake valve bodies typically use a single-specification fixed interface, which requires the replacement of adapters when connecting pipelines, resulting in low installation and connection efficiency and inconvenience. It facilitates efficient and convenient conversion of brake valves and pipelines with inconsistent interfaces, shortens the installation time for disassembling and replacing adapters, and facilitates the aggregation of various different specifications of brake valve body interfaces, improving the conversion convenience of the multi-specification interface conversion device for brake valve bodies. It is applicable to multi-specification interface conversion devices for brake valve bodies.
