Fasteners are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, etc., in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments Various types of fasteners can be seen in chemical industry, instrumentation and supplies, etc., which are the most widely used mechanical basic parts. The existing pipe joints use tapered nuts with poor fastening performance and cannot guarantee the tightness of the connection. So solid that the fluid leaks from the pipe joint connection, affecting the overall sealing of the pipeline transportation system, therefore, it is necessary to propose a tapered nut for pipe joints

Abstract
The invention discloses a conical nut for a pipeline joint. The conical nut for the pipeline joint comprises a first nut, a second nut, an anti-loose lock set and a locking nut; and the first nut alsocomprises a second nut connecting end, a shrinking groove, a first through hole and a threaded through hole. Compared with the prior art, the conical nut for the pipeline joint has the following advantages thatthe structure is simple and the design is reasonable; by a mode of providing a plurality of nuts and the anti-loose lock set, the locking property of the nut is greatly enhanced and the bolt connection reliability can be guaranteed within long time; and by a mode of providing a sealing ring in the nut, the sealing property of the nuts is enhanced, the fluid leakage probability is reduced and the conical nut for the pipeline joint is worthy of promotion.
Description
【Technical field】 [0001] The invention relates to the technical field of fasteners, in particular to a tapered nut for a pipe joint. 【Background technique】 [0002] Fasteners are a type of mechanical parts that are used for fastening connections and are widely used. Fasteners are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, etc., in various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments Various types of fasteners can be seen in chemical industry, instrumentation and supplies, etc., which are the most widely used mechanical basic parts. The existing pipe joints use tapered nuts with poor fastening performance and cannot guarantee the tightness of the connection. So that the fluid leaks from the pipe joint connection, which affects the overall sealing performance of the pipeline transportation system. Therefore, it is necessary...
