Technical Field

The invention relates to a butterfly valve oil leakage plugging tool, in particular to a plate-type butterfly valve oil leakage plugging tool for a power transformer, and belongs to the technical field of power transformer equipment.

Background

During the manufacturing process of the transformer, due to poor casting, assembly process, product and welding quality, air holes, desoldering phenomena, sand holes, insufficient welding, aging of a sealing rubber gasket and the like are caused, so that oil leaks from the transformer. The plate-type butterfly valve sealing rubber pad is mostly aged in the leakage of the transformer, the aging speed is higher due to the poor oil resistance of the sealing rubber pad, particularly, the aging speed is higher at high temperature, and the sealing rubber pad is easy to age, crack and deform to cause the leakage of the transformer. Because pressure exists in the transformer oil, no effective leakage stopping measure exists. At present, the leakage treatment of the plate-type butterfly valve usually adopts measures of strengthening the pretightening force of a connecting bolt, replacing the pretightening force and the like, but the oil leakage condition cannot be solved due to the deformation of a clamped bolt, the aging of a gasket, the reduction of the rebound force and the like, and the replacement of the plate-type butterfly valve requires the power failure and the field hoisting of a transformer, so that the service life of equipment is shortened, and the working strength of operators.
