the outlet flow passage 228 in the valve body unit communicates with the valve body outlet 229 or with the inlet flow passage 224 in an adjacent valve body unit.
In this embodiment, the diameter Φ of the split middle island ranges from 1/3 to 1/4 of the height of the annular cavity, and the included angle β of the blunt body ranges from 15 ° to 50 °. The flow channel width of the main flow channel 227 and the secondary flow channel 226 is 1/4 to 1/2 of the diameter phi of the split middle island.
When fluid flows from the inside of the cartridge 1 to the outside of the cartridge 1, the fluid enters the valve body inlet 223, and the fluid is split into the main flow channel 227 and the sub flow channel 226 after passing through the inlet flow channel 224, and merges in the outlet flow channel 228.
