Further, an exhaust valve 305 is arranged between the water pump water outlet 318 and the venturi water inlet 315.

Further, a bypass port 307 is provided in the vacuum circulation line 311.

Referring to fig. 1 to explain the operation principle of the equipment, before the equipment is started for the first time, water should be injected into the vacuum circulation pipeline 311 through the bypass port 307, the gas in the pipeline and the gas in the surge tank 306 are discharged through the exhaust valve 305 by the water injection, meanwhile, the water pressure of the vacuum circulation pipeline 311 is increased to more than 1bar, and then the equipment is started after the water injection is stopped; when the water pump 304 is started, water flow is pushed to flow towards the pressure stabilizing tank 306, the water pressure of the pressure stabilizing tank 306 and the venturi water inlet 315 is increased, and the water pressure of the venturi water outlet 316 is reduced, so that a large pressure difference is generated between the venturi water inlet 315 and the venturi water outlet 316, fluid jet flow is generated inside the venturi tube 300 under the action of the front-back pressure difference, the venturi throat 320 forms vacuum under the action of the jet flow, the venturi throat 320 is connected with the venturi suction inlet 303 through a one-way mechanism inside the venturi tube 300, and the venturi suction inlet 303 forms vacuum suction; after being sucked from the Venturi suction inlet 303 and mixed with water, the gas 314 flows out of a Venturi tube water outlet 316 to flow to the water pump 304, is pressurized by the water pump 304 and then flows into the pressure stabilizing tank 306, the flow rate of the fluid is greatly reduced due to the large volume in the pressure stabilizing tank 306 when the water vapor is in the pressure stabilizing tank 306, the gas 314 flows upwards and is discharged from the exhaust valve 305 when the flow rate is low, and the water 313 flows downwards and flows to the Venturi tube 300 again for circulation; when water and gas are separated, water pressure fluctuation can be caused because gas is discharged from the pressure stabilizing tank 306, the pressure stabilizing tank is provided with the air bag 319, and the water pressure stabilizing effect can be achieved through the expansion and contraction characteristics of compressed air in the air bag 319 and the air bag 319.

Referring to fig. 2 for explaining the application of the vacuum priming function of the device, the venturi suction inlet 303 is connected with the exhaust port 7 of the water inlet pipe of the water pump, a water level sensor 310 is arranged at the higher position of the vacuum priming tank 3, and the check valve 2 prevents the backflow of the external pipeline gas to influence the vacuum generation of the vacuum priming tank 3; the equipment pumps the gas in the vacuum water diversion tank 3 and the associated pipeline through the Venturi suction port 303 to form vacuum, the water in the low-level water tank is pumped into the vacuum water diversion tank 3 along with the increase of the vacuum degree, the water level of the vacuum water diversion tank 3 is fed back through the water level sensor 310, when the preset water level is reached, the equipment stops the vacuum pumping operation, the controller 309 sends a start-up signal to the water supply equipment, the water in the tank is pumped away after the pump station main pump 1 is started, and the water inlet 8 of the vacuum water diversion tank is supplemented with the same water amount; when the vacuum degree in the vacuum water diversion tank 3 is high, the gas rich in the water is concentrated in the vacuum water diversion tank 3 under the condition of vacuum negative pressure, so that the water surface in the vacuum water diversion tank 3 can descend, and the equipment can synchronously vacuumize to ensure that the water level of the vacuum water diversion tank 3 cannot descend when the pump station main pump 1 operates.

Referring to fig. 3 for the application of the vacuum water diversion function of the equipment, the venturi suction inlet 303 is connected with the exhaust port of the water inlet pipe of the pump station main pump 1, a water level sensor 310 is arranged at the higher position of the water inlet pipe of the pump station main pump 1, and the check valve 2 prevents the gas in the external pipeline from flowing backwards to influence the vacuum generation of the water inlet and outlet pipeline 10 of the pump station; the air in the water inlet pipe of the pump station main pump 1 is pumped out through the Venturi suction inlet 303 to form vacuum, along with the increase of the vacuum degree, the water in the low-level water tank 4 is pumped into the pump station water inlet and outlet pipeline 10 to flow into the pump station main pump 1, the water level of the pump station water inlet and outlet pipeline 10 is fed back through the water level sensor 310, when the preset water level is reached, the vacuum pumping operation is stopped, the controller 309 sends a start-up signal to the water supply equipment, and the water in the low-level water tank 4 can be sucked up through self-suction when the pump station main pump 1 is started due to the vacuum state of the pump station water inlet and outlet pipeline 10; because when the pump station goes out the inlet channel 10 in the vacuum degree when higher, the aquatic is rich in gas under the condition of vacuum negative pressure, and gas can be continuous to separate and concentrate in pump station goes out inlet channel 10, makes the surface of water that the pump station goes out in the inlet channel 10 can descend, can be when pump station main pump 1 operation, and the synchronous evacuation can not descend in order to guarantee the pump station to go out the water level in the inlet channel 10.
