[0002] A busbar is a fixture that can bring together multiple fluid channels, also known as a media distribution plate, valve plate or valve seat. It is widely used in pneumatic control circuits and, of course, also in liquid control circuits. It can achieve centralized supply and discharge of media and save the occupied space. There are at least two respectively penetrating channels in the busbar, namely an inlet and an outlet. The medium at the inlet is supplied by a gas source or a liquid source. After being distributed by the busbar, the medium coming out of the outlet is connected to the components that require the medium in the complete set of equipment through the connection of accessories such as hoses and connectors.

The first medium channel 12 is arranged along the length direction of the manifold plate body 10. In this embodiment, the first medium channel 12 is the main medium channel. The first inlet 11 is arranged at the end of the manifold plate body 10. In the present utility model, the first inlet 11 is arranged on the upper end surface of the manifold plate body 10. Of course, it can also be arranged on the side end of the manifold plate body 10. The first inlet 11 is communicated with the first medium channel 12 through the first main valve port 13. At the position of the manifold plate body 10 corresponding to the first main valve port 13 is provided a first installation port 20. The first installation port 20 penetrates through the upper end of the manifold plate body 10. The first installation port 20 is used for installing a main control valve A 30 for controlling the on - off of the first main valve port 13. Specifically, the first main valve port 13 is arranged at the lower end of the first installation port 20 and the diameter of the first installation port 20 is larger than the diameter of the first main valve port 13. The manifold plate body 10 is provided with a first flared groove 21 at the position of the first installation port 20 adjacent to the first inlet 11. The first inlet 11 is communicated with the first main valve port 13 through the first flared groove 21. Further, the flow - through cross - section of the first flared groove 21 is larger than the flow - through cross - section of the first inlet 11, so that the medium flow rate between the end of the first inlet 11 and the first main valve port 13 per unit time can be greatly increased.
[0031] The first medium channel 12 is in communication with the outlet A14 and the outlet B15. An independent valve port 50 corresponding to the outlet B15 one by one is provided in the manifold body 10. The first medium channel 12 communicates with the corresponding outlet B15 through the independent valve port 50. The manifold body 10 is provided with a second mounting port 51 corresponding to the independent valve port 50 one by one. An independent control valve 40 for controlling the on-off of the independent valve port 50 is installed in the second mounting port 51. The manifold body 10 is provided with a second flared groove 52 at a position adjacent to the first medium channel 12 in the second mounting port 51. The first medium channel 12 communicates with the independent valve port 50 through the second flared groove 52. The manifold body 10 is provided with a communication port 16 corresponding to the second flared groove 52 one by one and used for communicating the second flared groove 52 with the first medium channel 12. The flow channel cross-section of the second flared groove 52 is larger than that of the communication port 16. In the present utility model, the second flared groove 52 is arranged on the first medium channel 12, that is, at least part of the area of the second flared groove 52 overlaps with the first medium channel 12. The communication port 16 is the intersection of the second flared groove 52 and the first medium channel 12. The second flared groove 52 penetrates through the first medium channel 12 to introduce the medium in the first medium channel 12 into the second flared groove 52 as much as possible. When the independent valve port 50 is opened, it can ensure that the medium can enter the independent valve port 50 with a larger flow rate per unit time, and thus enter the outlet B15 with a larger flow rate.
[0032] In the present utility model, the number of the outlets A14 and the outlets B15 is matched and is multiple. The outlets A14 and the outlets B are both arranged at the lower end of the manifold body 10. The manifold body 10 is provided with a convex portion protruding downward at a position corresponding to the first medium channel 12. The outlets A14 and the outlets B15 are arranged at the center of the corresponding convex portion. The outlet A14 is arranged directly below the first medium channel 12, and the outlet B15 is arranged beside the first medium channel 12.
[0033] The usage principle of the high-flow manifold of the present utility model after being assembled into a valve group: When the main control valve A30 is opened, the medium in the first inlet 11 sequentially passes through the first flared groove 21 and the first main valve port 13 and enters the first medium channel 12. Part of the medium entering the first medium channel 12 passes through the outlet A14 and is introduced into the corresponding driving member. Part of the medium entering the first medium channel 12 enters the second flared groove 52. When the independent control valve 40 at the independent valve port 50 is opened, the medium in the second flared groove 52 can enter the outlet B15 through the opened independent valve port 50 and finally be introduced into the corresponding driving member through the outlet B15. When the main solenoid valve A is closed, the first main valve port 13 is cut off, and at this time, no medium enters the outlets A14 and B15 from the first medium channel 12.
[0034] In some embodiments, the bottom end of the first flaring groove 21 is lower than the bottom end of the first inlet 11, and the top end of the first flaring groove 21 is higher than the first main valve port 13. Through this setting, the first flaring groove 21 can completely cover the area of the first inlet 11, so as to introduce the medium at the first inlet 11 into the first flaring groove 21 as much as possible. When the first main valve port 13 is opened, it can ensure that the medium can be introduced into the first main valve port 13 with a larger flow rate per unit time, and thus enter the first medium channel 12 with a larger flow rate.
[0035] In some embodiments, the bottom end of the second flaring groove 52 is lower than the bottom end of the communication port 16. In the present utility model, that is, the bottom end of the second flaring groove 52 is lower than the bottom end of the first medium channel 12, and the top end of the second flaring groove 52 is higher than the independent valve port 50. Similarly, the second flaring groove 52 is set to completely cover the area of the communication port 16, so as to introduce the medium at the communication port 16 into the second flaring groove 52 as much as possible. When the independent valve port 50 is opened, it can ensure that the medium can be introduced into the independent valve port 50 with a larger flow rate per unit time, and thus enter the outlet B15 with a larger flow rate.

At the side end of the confluence plate body 10, there are provided communication holes 68 for communicating the corresponding outlet C63s and outlet D64s with the second medium channel 61. The communication holes 68 penetrate through the side end of the confluence plate body 10. A first sealing plate 70 for sealing the communication holes 68 is installed on the confluence plate body 10. The communication holes 68 are arranged as process holes, that is, they can be processed more efficiently.
