The invention also comprises the following steps:
the method comprises the following steps: constructing an interface valve system; firstly, two ends of an interface valve are respectively connected with a closestool 3 and an ejector; then the air flow channel 20 at the left end of the ejector is respectively connected with the vacuum dirt storage tank 12 and the pressure stabilizer 13, the outer flow channel 22 at the left end of the ejector is externally connected with a compressed air source, and the spray head 9 at the right end of the ejector is connected with the vacuum dirt storage tank 12; finally, the lower end of the voltage stabilizer 13 is connected with the lower end of the regulator, the upper end of the regulator is connected with the vacuum pump, and the left end of the regulator is connected with the vacuum dirt storage tank 12;
step two: the pressure in the interface valve system is regulated by an ejector and a regulator: the regulator feeds back the negative pressure signal in the interface valve system in time and adjusts the negative pressure value of the ejector.
The working process of the invention is as follows:
the invention relates to an intelligent interface valve for sewage collection and a variable control method, which are explained in the working process by combining with the attached drawings.
When the negative pressure is interrupted, the regulator regulates the vacuum pump to generate linkage. The jet device is a nozzle type jet device, generates vacuum through jet flow and is a negative pressure booster. The jet nozzle 8 can move left and right under the action of the first piston 6, and the movement is limited to some extent due to the square bulge 21; after the jet nozzle 8 moves to the right, the gap between the jet nozzle 8 and the spray head 9 is reduced, the speed is increased, and the negative pressure is increased; that is, when the pressure of the vacuum waste storage tank 12 connected to the ejector becomes high, the pressure in the left chamber of the first piston 6 is made higher than the pressure in the pressurizer 13 connected to the right chamber, so that the first piston 6 can move to the right with the jet nozzle 8, and the negative pressure is increased. The vacuum pump 18 is used for vacuumizing the vacuum sewage storage tank 12, every time when vacuumizing is carried out, the vacuum sewage storage tank 12 has a certain volume, and particularly when the vacuum sewage storage tank is frequently started, the vacuum cannot be achieved at once; the volume of the vacuum dirt storage tank 12 is far larger than the volume of the pressure stabilizer 13 and the regulator lower shell 14, when the vacuum pump 18 starts pumping, as shown in an enlarged view B in the attached drawing, an L-shaped hole in the second piston 15 serves as a flow channel to communicate the chambers, and once the vacuum pump is started, the chamber below the regulator lower shell 14 easily reaches negative pressure, such as 40KPA, but the chamber on the left side of the regulator lower shell 14 connected with the vacuum dirt storage tank 12 does not reach the same negative pressure, such as only 50 KPA; at this time, the second piston 15 is pressed against the elastic force of the elastic piece 16 to move upwards under the pressure difference, so that the third L-shaped hole 27 is closed; the regulator can respond in time when the pressure of the vacuum sewage storage tank 12 changes.
The invention can utilize the regulator to adjust the negative pressure value of the ejector through the feedback of the negative pressure signal, and ensure that the interface valve has enough negative pressure, thereby solving the problem of insufficient pressure during continuous use.
The above embodiments are illustrative of the present invention, and are not intended to limit the present invention, and any simple modifications of the present invention are within the scope of the present invention.
