Description

Be used for pipe thread seal structure Technical Field The utility model relates to the technical field of power systems, in particular to a sealing structure for a pipe thread. Background In the current power system, grease film-coated dry products are increasingly widely applied, although a dry transformer mainly runs in a dry mode, a small amount of liquid (such as silicone oil) is still used as an insulating or auxiliary material in certain parts or components, and at present, the product pipe fitting seals silicone oil in the product through a combined structure of a threaded part structure and a threaded sealant. According to the running conditions of many years, some running products have the problem of leaking silicone oil, so that the combined structure of a thread part structure and a thread sealant can not completely meet the sealing requirement, if the silicone oil leaks, the related electrical performance of main insulation of the products can be influenced, and the utility model provides a sealing structure for a pipe thread, which aims at overcoming the defects of the prior art, and solves the problems. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a pipe thread sealing structure, which is used for realizing sealing by extruding a rubber ring through matching of a sealing connecting pipe, a sealing ring and a fastening ring, has reliable sealing performance, ensures the product quality, has simple and convenient processing and operation, can adjust the sizes of parts according to the actual conditions of the product, has flexible processing and wide application range, is simple in assembly and part processing operation, and is suitable for mass production. The utility model is realized by the following technical scheme that the sealing structure for the pipe thread comprises a sealing connecting pipe, wherein the end part of the sealing connecting pipe is provided with a thread part, and a circumferential sealing groove is processed at the corresponding position; a rubber ring is movably clamped in the annular sealing groove of the sealing connecting pipe; The outer side of the sealing connecting pipe is in threaded connection with a sealing ring and a fastening ring; the sealing ring, the fastening ring and the sealing connecting pipe realize axial sealing of the sealing connecting pipe by extruding the rubber ring. Preferably, a thread part is machined in the sealing ring, and a sealing groove with an oblique angle structure is machined on one side of the sealing ring. Preferably, the fastening ring is internally provided with a threaded portion. Preferably, the rubber ring is movably clamped at the sealing groove machined by the sealing connecting pipe and the sealing ring. Preferably, a double-nut structure is formed between the sealing ring and the fastening ring and the sealing connecting pipe respectively, and the double-nut structure is used for clamping and limiting the rubber ring. The utility model discloses a sealing structure for a pipe thread, which has the following beneficial effects: The sealing structure for the pipe thread is characterized in that 1, the sealing is realized by extruding a rubber ring through the cooperation of a sealing connecting pipe, a sealing ring and a fastening ring, the sealing performance is reliable, and the product quality is ensured; 2.
