Description

Technical Field

[0001] The present invention relates to the technical field of valve groups, and in particular to a multi-channel control valve group. Background Art

[0002] The valve group includes a manifold and several solenoid valves or gas-controlled valves arranged on the manifold. The solenoid valves are used to control the opening and closing of the medium channel inside the manifold as a whole or individually. The existing valve group is widely used in refrigeration systems. For example, the valve group in the refrigeration compressor is an important component for controlling the suction and exhaust of the compressor. When the compressor is working, the working fluid enters and exits the cylinder through the valve group.

[0003] A manifold is a fixed object that can bring together multiple fluid channels. It is also called a medium distribution plate, valve plate or valve seat. It is mostly used in pneumatic control circuits, and of course also in liquid control circuits. It can realize centralized supply and centralized discharge of media and save space. There are at least two channels running through the manifold, namely the inlet and the outlet. The inlet medium is supplied by a gas source or a liquid source. After being distributed by the manifold, the medium coming out of the outlet is connected to the components in the complete set of equipment that need the medium through the connection of hoses, joints and other accessories.

[0004] However, the current valve group has the problems of large size and low integration, which makes it unsuitable for use in space-constrained environments; if the size of the manifold is reduced, the medium flow rate per unit time in the flow channel will be smaller. Therefore, how to achieve miniaturization of the manifold while ensuring a high flow rate per unit time is a technical problem that needs to be solved urgently. In addition, the control method of the existing valve group medium channel is relatively simple. Summary of the invention

Specifically, the first main valve port 13 is provided at the lower end of the first mounting port 20 and the diameter of the first mounting port 20 is larger than the diameter of the first main valve port 13. The busbar body 10 is provided with a first expanding groove 21 at a position of the first mounting port 20 adjacent to the first inlet 11. The first inlet 11 is connected to the first main valve port 13 through the first expanding groove 21. Furthermore, the flow channel cross-section of the first expanding groove 21 is larger than the flow channel cross-section of the first inlet 11, so that the medium flow rate from the end of the first inlet 11 to the first main valve port 13 per unit time can be greatly increased.

[0032] The first medium channel 12 is communicated with the outlet A14, and the first medium channel 12 is communicated with the outlet B15. An independent valve port 50 corresponding to the outlet B15 is provided in the busbar body 10, and the first medium channel 12 is communicated with the corresponding outlet B15 through the independent valve port 50. The busbar body 10 is provided with a second mounting port 51 corresponding to the independent valve port 50, and an independent control valve 40 for controlling the on-off of the independent valve port 50 is provided at the second mounting port 51. The busbar body 10 is provided with a second expansion groove 52 at a position adjacent to the first medium channel 12 at the second mounting port 51, and the first medium channel 12 is communicated with the independent valve port 50 through the second expansion groove 52.
