Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-4, the isolation microwave control type cut-off pipe valve comprises a main pipeline 1, an elastic inner core pipe 2 and two microwave heater modules 3; a plurality of limiting ropes 4 are uniformly and fixedly connected between the inner surface of the main pipeline 1 and the outer surface of the elastic inner core pipe 2; the limiting ropes 4 are coated with waterproof paint; the inner surface of the elastic inner core pipe 2 is uniformly and fixedly connected with a plurality of elastic partition plates 5 along the vertical direction; an expansion cavity 6 is formed between every two adjacent elastic partition plates 5; an elastic ball 7 with a cavity inside is arranged in the expansion cavity 6; ether is filled in the elastic ball 7; the outer surface of the main pipeline 1 is fixedly sleeved with a plurality of limiting rings 8; a limiting groove 9 is formed between every two adjacent limiting rings 8; the thickness of the limiting grooves 9 is consistent with that of the corresponding expanding cavities 6; the output ends of the two microwave heater modules 3 form a closed ring 10; the diameter of the inner surface of the closed circular ring 10 is consistent with the diameter of the outer surface of the main pipeline 1; the closed circular ring 10 is in sleeve fit with the main pipeline 1; the thickness of the output ends of the two microwave heater modules 3 is consistent with that of the limiting groove 9; the output end of the left microwave heater module 3 and the output end of the right microwave heater module 3 are both provided with a shielding case 11; the upper end and the lower end of each elastic ball 7 are fixedly connected with a fixed rope 12; the upper end of the upper fixing rope 12 is fixedly connected with the central part of the lower end surface of the corresponding upper elastic partition plate 5; the lower end of the lower fixing rope 12 is fixedly connected with the center part of the upper end surface of the corresponding lower elastic partition plate 5.

When the invention is used:

when a leakage condition occurs at a certain position of the main pipeline 1, finding the position, clamping the output ends of the two microwave heater modules 3 in the upper limiting groove 9 close to the position, starting the two microwave heater modules 3, heating the expanding cavity 6 corresponding to the limiting groove 9, heating the elastic ball 7 in the expanding cavity 6, quickly vaporizing the ether in the elastic ball 7 by heating, losing the effect of the microwave heater modules 3 after the ether is vaporized, increasing the volume after the ether is vaporized, because the ether is wrapped by the elastic ball 7, the elastic ball 7 expands under the influence of the ether, the expansion of the elastic ball 7 can extrude the elastic core pipe 2 to expand and pull the elastic partition plate 5 to extend, so that the outer surface of the position of the elastic core pipe 2 is attached to the inner surface of the main pipeline 1, the upper part of the leakage position is blocked, and the liquid in the main pipeline 1 can not flow through the leakage position any more, therefore, the liquid existing in the main pipeline above the leakage position can not be leaked any more, and the repair can be carried out in time.
