Chinese patent CN201120311314.5 discloses a thimble type leaking stoppage body and pipeline rush-repair fixture for pipeline rush-repair, the thimble type leaking stoppage body includes the cone and the rotary guide drilling tool that is connected with the cone drive, and rotary guide drilling tool includes: spanner, outer lead screw and supporting body, outer lead screw pass the inner wall utensil screwed mesopore of supporting body and with supporting body threaded connection, outer lead screw one end and spanner fixed connection, the other end and the cone drive of outer lead screw are connected. The pipeline emergency repair clamp comprises a thimble type leaking stoppage body and a fastening part for fixing the thimble type leaking stoppage body and a pipeline relatively. The utility model discloses with strong points, belong to the equipment of salvageing of not failing of quick high pressure, have compact structure, small and exquisite light, swift high efficiency, the practicality is strong, has the leaking stoppage effect of instant sight to the pipeline sand eye leak opening below 5mm, prevents effectively that the loss from further expanding. Due to the expansion caused by heat and contraction caused by cold, the existing plugging fixture is easy to have the condition of loose fit between the gasket and the pipeline in winter, so that the production is influenced by replacing the plugging fixture again, and the production cost is increased.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a heterotypic leaking stoppage fixture has solved leaking stoppage fixture when temperature reduces and has appeared laminating not tight problem.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides a special-shaped plugging fixture, which comprises an upper fixture, a lower fixture and a bolt, wherein a pair of limiting rings are symmetrically arranged at two ends of the outer wall of the upper fixture and the outer wall of the lower fixture, and the bolt penetrates through the limiting rings at the corresponding positions of the upper fixture and the lower fixture; the outer walls of the upper fixture and the lower fixture are connected through a spring, and the spring is positioned in the center of a joint seam on one side of the upper fixture and one side of the lower fixture; go up fixture and lower fixture inner wall laminating and be provided with the piece that generates heat, the piece inner wall laminating that generates heat is provided with the honeycomb and fills up.

Furthermore, the cross sections of the upper fixture and the lower fixture are semicircular arcs with equal diameters.

Furthermore, the inner diameters of the upper clamp and the lower clamp are 3mm-8mm larger than the outer diameter of the leakage pipeline.

Furthermore, the heating sheet is a PET electric heating film polyester heating sheet, the energy consumption of the PET electric heating film polyester heating sheet is low, the heat conversion rate is high, and the heating sheet is suitable for heating appliances with special shapes and concave-convex surfaces.

Further, the temperature of the PET electrothermal film polyester heating sheet is 16-22 DEG C

Furthermore, the honeycomb sealing gasket is made of polytetrafluoroethylene or rubber.

The technical effects of the utility model:

compared with the prior art, the special-shaped leaking stoppage fixture solves the problem that the leaking stoppage fixture is not tightly attached when the temperature is reduced by arranging the heating sheet between the fixture and the gasket; the spring between the clamps is arranged, so that the clamps are effectively prevented from being separated, and the installation of the clamps is facilitated; the device has the advantages of simple structure, no need of production halt and field welding, reduction of loss caused by equipment isolation or start-stop, safe and reliable technology, no pollution, energy and manpower conservation, and capability of timely and effectively treating leakage accidents.
