Abstract

The invention discloses a screwed pipe joint comprising a post body, wherein a channel is arranged in the post body. The screwed pipe joint is characterized in that the middle part of the post body is provided with a raised turncap, the post body of the left side of the turecap is a cone-shaped body, the outer end of the cone-shaped body is an external tread section, the inner end of the cone-shaped body is a polish rod section, and the post body of the right side of the turncap is provided with external threads. Compared with clamping sleeve or clamping press joints used for connection, the invention has good connection performance, is convenient to assemble or disassemble, saves time and labor, is economical and practical and has long service life.

Description

Technical field: [0001] The invention mainly relates to a pipeline connection device, in particular to a threaded pipe joint. Background technique: [0002] Pipelines have been widely used in industry, agriculture, and urban construction. In order to save pipelines, there are many types of cast copper joints and plastic pipe joints that are not widely used in the market. Most of them are connected by ferrule or compression joints. The installation Or dismounting is not only loaded down with trivial details, laborious, and connection stability performance is low, can't satisfy people's needs. Invention content: [0003] In order to make up for the defects of the prior art, the present invention provides a threaded pipe fitting joint, which adopts threaded connection and solves the problem of cumbersome and laborious installation or disassembly of ferrule or compression joint connection, as well as poor connection stability. [0004] The present invention is achieved throug...
