Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, a vacuum suppressor for non-negative pressure equipment according to the utility model includes a housing 1, a baffle 3 and a flange 5, and the upper part of the housing 1 is provided with a baffle 3 , the bottom of the housing 1 is connected with a flange 5; it also includes a first waterproof electromagnetic valve 6, a water level sensing probe 7, a second waterproof electromagnetic valve 8, a waterproof wire 9 and a PLC controller 10, the first waterproof electromagnetic valve 6 is set above the filter through hole 4 in the middle of the baffle 3; the second waterproof electromagnetic valve 8 is set on the upper right side of the housing 1; the water level sensing probe 7 is set on the right side of the bottom of the baffle 3; the PLC The controller 10 is arranged on the upper right side of the housing 1 , and the PLC controller 10 is connected to the first waterproof electromagnetic valve 6 , the water level sensing probe 7 and the second waterproof electromagnetic valve 8 through waterproof wires 9 .

The bottom of the first waterproof electromagnetic valve 6 is covered with a sealing ring 2 .

When the utility model is in use, the housing 1 is divided into upper and lower chambers by using the baffle plate 3. The upper chamber is an air chamber, and the lower chamber is a water chamber. , the water level sensing probe 7 transmits the water level parameters to the PLC controller 10, and the PLC controller 10 controls the first waterproof electromagnetic valve 6 to close, and now the water pressure in the whole set of non-negative pressure equipment is consistent with the water pressure of the municipal pipe network. When the pressure of the municipal pipe network decreases, the water level in the water chamber drops, and the water level sensor probe 7 transmits the water level parameters to the PLC controller 10, and the PLC controller 10 controls the first waterproof electromagnetic valve 6 and the second waterproof electromagnetic valve 8 to open simultaneously, This moment, the air pressure in the whole set of non-negative pressure equipment drops to atmospheric pressure.

The utility model adopts a baffle on the upper part of the shell, a filter through hole in the middle of the baffle, a water level sensing probe on the right side of the bottom of the baffle, and a first waterproof electromagnetic valve above the filter through hole of the baffle. , the second waterproof electromagnetic valve is set on the upper right side of the housing, and the opening of the first waterproof electromagnetic valve and the second waterproof electromagnetic valve is controlled by the PLC controller; it has the advantages of convenient operation, simple structure, convenient maintenance, good sealing, and intelligent Higher, can prolong the service life.

The above is only a preferred embodiment of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the utility model patent application scope are all included in the utility model patent application scope .
