Model utility content
The purpose of this utility model is to design a kind of pipeline plug that user cost is low, shutoff process is simple, sealing characteristics is good that has.
Consider the problems referred to above of prior art, according to an aspect of the present utility model, for solving above-mentioned technical problem, the utility model by the following technical solutions:
Structure of the present utility model as shown in Figure 1, mainly comprises backplate 1, air bag 2, clamping plate 3, piston 4, center tube 5, spigot 10.At center tube 5 overcoat air bags 2, the axial both sides of center tube 5 are respectively fixed a backplate 1 with clamping plate 3 by multiple screw I 9, the center of two clamping plates 3 is respectively provided with a hole 6 that holds piston 4, corresponding, on the backplate 1 of fitting with described clamping plate 3, be also provided with the hole 7 that holds piston 4, the have elastic component part of 8 piston 4 of band is positioned at the step-like hole 6 of clamping plate 3, another part is positioned at the hole 7 of a backplate 1 of fitting with these clamping plate 3, the macropore drive fit in the step-like hole 6 on piston 4 and clamping plate 3, supports the aperture that blocks up step-like hole 6; In the outer side center of clamping plate 3, by screw II 11 spigot 10 that is connected, described spigot 10 is suction port.
Described backplate 1 is plectane, and hole 7 is stated at its center to some extent, has multiple holes of wearing screw I 9 with center tube 5 contacting points;
Described air bag 2 is inner tube shape, and has multiple pores to communicate with the pore of the corresponding number on center tube 5 in the inner side of air bag;
On described two pistons 4, be all provided with elastic element 8;
Described center tube 5 is short pipe, has multiple pores radially at the middle part of short pipe, respectively has multiple axial holes on the tube wall of two ends.
Compared with prior art, the beneficial effects of the utility model are:
Pipeline plug of the present utility model, adopts feed mechanism to send into pipeline, and can implement shutoff to pipeline apart from 1 meter of position far away of pipeline tapping place.While implementing shutoff, determine behind position, can send pressurized gas to from spigot 10, air bag 2 is inflated, tensioning inner-walls of duct.The utlity model has the advantage that user cost is low, shutoff process is simple, sealing characteristics is good.Plugging device of the present utility model not only can be realized two-way self-unsealing, is applicable to the two-way shutoff of pipeline, and can bear the oil gas pressure difference of blocking of 0.1MPa, can effectively prevent that in construction period oil gas from missing the region of getting angry, and guarantees construction safety.
