Description of working principle and action relation:
the integrated control valve group utilizes compressed air to push three sets of pneumatic valve cores in the valve seat 1 of the air inlet valve to realize the movement of the piston, so as to realize the air inlet and pressure equalizing effects of the equipment.
And (3) tower A is filled with air: before compressed air enters, the inner side quick-plug elbow 10 above the air inlet valve core component 3 of the A tower enters the middle closed space of the air passage through pilot air, the pressure is continuously increased, the valve core component 3 of the A tower is pushed to move outwards, the inner side air passage closed space is communicated with the air passage 7 of the compressed air and the air passage and the cavity of the A tower on the end cover 9, at the moment, the compressed air enters, and the air inlet effect of the A tower is realized, as shown in fig. 3.
After the air intake of the A tower is completed, the outer side quick-inserting elbow 10 above the air intake valve core assembly 3 of the A tower enters the airtight space outside the air passage through pilot air, the pressure is utilized to push the valve core of the A tower to move inwards, the valve core of the A tower is reset, and the air intake path of the A tower is closed.
Pressure equalizing of AB tower: and after the air inlet of the tower A is completed, performing the pressure balancing action of the two towers AB. The upper inner side of the pressure equalizing valve core assembly 5 is quickly inserted and directly communicated 11, pilot gas enters the middle closed space of the air passage, the pressure equalizing valve core assembly 5 is pushed to move outwards after the pressure is continuously increased, the inner side air passage closed space is opened, and the air passage of the A, B tower on the end cover 9 is communicated with the cavity.
Because the pressure of the tower A is high, the pressure of the tower B is low, gas flows through the air passage of the end cover 9 from the tower A, flows into the pressure equalizing hole 12 of the tower A on the valve seat 1 of the air inlet valve, flows out from the pressure equalizing hole 12 of the tower B on the valve seat, flows through the air passage of the tower B on the end cover 9, and flows to the tower B, thereby realizing the pressure equalizing effect of the tower AB.
In the pressure equalizing process, the air inlet valve core component of the AB tower is in a closed state, and the air has only one path for pressure equalizing. After the pressure equalization of the AB tower is completed, the outside of the upper part of the pressure equalization valve core assembly 5 is quickly inserted and directly communicated 11, pilot gas enters an external airtight space of the air flue, the pressure is utilized to push the pressure equalization valve core to move inwards, the pressure equalization valve core is reset, and a pressure equalization gas path is closed.
B, tower air inlet: after the pressure equalization of the AB tower is completed, the air inlet valve core of the B tower acts, the air inlet of the B tower is realized, and the process is the same as the air inlet mode of the A tower. And after the air intake of the tower B is completed, the pressure equalizing of the BA is carried out, and the process is the same as that of the AB. At this time, one action cycle is completed for about 2min, and then a cycle circulation action is performed, so that the cycle air inlet and pressure equalizing effects of the equipment are realized.
In summary, the three valve core assemblies and the corresponding air passages in the valve seat replace the traditional angle seat valve and pipeline structure, the structure is more compact, the space of the control part is saved by more than 60%, and the whole volume of the device is greatly reduced.
Meanwhile, the pipeline structure is replaced by the corresponding air passage in the valve seat, so that the threaded connection and welding structure are avoided, and the stability of the equipment control structure is greatly improved.
And the three sets of valve core assemblies are positioned in the valve seat, so that the contact with the outside air is reduced, the dust prevention and rust prevention are realized, and the maintenance cost of the equipment control part is effectively reduced.
The foregoing is a preferred embodiment of the present utility model; the scope of the utility model is not limited in this respect. Any person skilled in the art, within the technical scope of the present disclosure, may apply to the present utility model, and the technical solution and the improvement thereof are all covered by the protection scope of the present utility model.
