Well tire bag seal device of the present invention, in heat-collection well, adopt the curing bag body of making by elastomeric material, curing bag body water-filling can be divided into two parts with heat-collection well after expanding, because tire bag seal device is provided with charging pipe and carries out water-filling, be provided with the pressure in the balance pipe control curing bag, so its working stability is reliable, can explosion, long service life, and sealing effectiveness is good.
Description of drawings
Fig. 1 is the front view of well of the present invention with tire bag seal device embodiment;
Fig. 2 is for using the schematic diagram of well of the present invention with the heat-collection well of tire bag seal device.
The specific embodiment
With reference to figure 1 and Fig. 2, Fig. 1 is the front view of well of the present invention with tire bag seal device embodiment, well of the present invention comprises sealing 6 with tire bag seal device, lower seal portion 10, charging pipe 1, balance pipe 2 and curing bag body 9, last sealing 6 and lower seal portion 10 are fixed on the outer wall of suction hose 8 in the heat-collection well respectively hermetically, curing bag body 9 is made by rubber, be the dolioform of both ends open, its external diameter from the centre up and down two ends reduce gradually, the upper port of curing bag body 9 and lower port are installed in respectively in sealing 6 and the lower seal portion 10 hermetically, charging pipe 1 and balance pipe 2 penetratingly be fixed on the sealing 6 and with curing bag body 9, last sealing 6, the cavity that lower seal portion 10 and suction hose 8 outer walls are surrounded communicates.Wherein go up sealing 6 and lower seal portion 10 and comprise flange 4, flange platen 5 and trip bolt 3 respectively, flange 4 is fixed on the outer wall of suction hose 8 hermetically, flange platen 5 is fixed on the flange 4 by trip bolt 3, the upper port of curing bag body 9 and lower port are equipped with cyclic sealing gasket 7, cyclic sealing gasket 7 is pressed between flange 4 and the flange platen 5, plays sealing function.In order to protect tire bag seal device not to be damaged, the diameter of flange 4 should be slightly larger than the external diameter of curing bag body 9 maximum when not expanding.
Fig. 2 is for using the schematic diagram of well of the present invention with the heat-collection well of tire bag seal device, this heat-collection well comprises well casing 20, suction hose 8, immersible pump 17, well head heat exchanger 11 and return pipe 14 and back-water valve (BWV) 12, well shown in Figure 1 tire bag seal device 19 is installed on suction hose 8, this well is provided with filling valve 13 with the charging pipe 1 of tire bag seal device 19, and link to each other with return pipe 14, balance pipe 2 is fixed on the sealing 6 vertically.When the tire bag seal device in the heat-collection well is worked, back-water valve (BWV) 12 and filling valve 13 are opened, immersible pump 17 work, by charging pipe 1 water-filling in the tire bag chamber that is surrounded by curing bag body 9, last sealing 6, lower seal portion 10 and suction hose 8 outer walls, and control pressure in the tire bag chamber by the height of water levels in the balance pipe 2, when the water in the balance pipe 2 was annotated height 20 meters left and right sides, the hydraulic pressure in the tire bag chamber was about two atmospheric pressure, closed filling valve 13 this moment.Produce strain behind curing bag body 9 compressive deformations and expand, closely contact with well casing 20 inwalls and reach sealing effectiveness.Because the heat-collection well separated into two parts, immersible pump 17 is from heat-collection well bottom suction with tire bag seal device 19 for well, backwater is to heat-collection well top, flows back to undergroundly then, and to separate heat-collection well be two-part purpose thereby reach.When needs take out well with tire bag seal device 19, close back-water valve (BWV) 12, open filling valve 13, at this moment, the liquid level in the balance pipe 2 is owing to the draining of return pipe 14 reduces, thus the pressure in the reduction tire bag chamber, up to consistent with external water pressure, the curing bag body is eliminated strain, makes its external diameter less than flange 4 diameters, and well can take out smoothly with tire bag seal device 19.
