[0027] A pressure gauge 8 is installed on the valve island manifold 7;

[0031] The check valve 13 is provided between the pressurizing port 10 and the positive pressure port 12 .

[0032] In one embodiment of the utility model, the valve group applied to the independent vacuum system solves the problems in the prior art, and arranges the sewage suction solenoid valve 1 to the vacuum solenoid valve 6 on the valve island manifold 7. At the same time, the valve island manifold 7 is also provided with an electrical connector 9, a hub 14, a pressure gauge 8 and a check valve 13. The line connections of all the solenoid valves are connected to the check valve 13 by plugging. The check valve 13 concentrates all the lines on the electrical connector 9. The controller can control the action of the solenoid valve by connecting a corresponding multi-core cable. The pipeline connection only needs to connect the control components to the outside. There is no need to take over between the solenoid valves. The connection is completed in the valve island manifold 7. It has the advantages of simple structure, setting the external complex pipeline connection into the valve island manifold 7, integration, and space saving.

[0033] like Figure 3 to Figure 4 As shown, as a preferred embodiment of the utility model, the sewage suction solenoid valve 1 and the sewage discharge solenoid valve 2 are direct-acting normally open two-position three-way solenoid valves, and the sewage suction solenoid valve 1 and the sewage discharge solenoid valve 2 are connected to the fully open sewage discharge valve;

The exhaust solenoid valve 3, the pressurizing solenoid valve 4, the air intake solenoid valve 5, and the vacuum solenoid valve 6 are direct-acting two-position two-way solenoid valves. When the valve group is used in an independent vacuum system, the action logic is as follows:

[0037] Positive pressure: The system monitors the pressure signal first. If the pressure signal is lower than the set value, the vacuum solenoid valve 6 is opened and the positive and negative pressure pumps pressurize the pressure tank 15. When the pressure signal reaches the set value, the pump is stopped.

[0038] Vacuuming: Check the negative pressure value in the transition tank. If it does not reach the set value, start the positive and negative pressure pumps, open the exhaust solenoid valve 3 and the intake solenoid valve 5, and close them when the pressure reaches the set value; wait for flushing;
