Problems solved by technology

When there is a problem, the pipeline needs to be repaired or rebuilt, which will inevitably involve disassembly. The pipeline connected by ordinary pipe joints also needs to use a pipe wrench when disassembling, which is troublesome, and there are problems such as rust and deformation in thread disassembly.

Embodiment Construction

[0007] like figure 1 As shown: there is an inner step on the inner wall at the right end of the pipe joint 1; a sealing ring 2 is placed on the inner step; on the right side of the sealing ring 2, there is a positioning sleeve 3 that presses the sealing ring 2 on the end face of the inner step, and the positioning sleeve 3 The inner wall is trumpet-shaped, and the big end of the horn is facing right; there is an internal tooth lock washer 4 inside the positioning sleeve 3. There are several axial gaps at the left end of the tight washer 4; there is a pipe sleeve 5 on the right side of the inner tooth lock washer 4, the left end of the pipe sleeve 5 is in the shape of a horn close to the inner wall of the positioning sleeve 3, and the right end is a cylinder shape, and the outer diameter of the cylinder is smaller than the large end diameter of the horn, forming an outer step at the joint between the cylinder and the horn; there is a plug sleeve 6 between the outside of the cyl...

Abstract

The invention discloses a plug-type self sealing pipe joint, wherein the pipe joint is formed through the following process: precise casting, tube extrusion or impact briquetting, oil pressure and the like, then the pipe joint, an elastic sealing ring, a position sleeve, a internal tooth lock washer, a pipe sleeve, a plug sleeve are assembled, shaping through the extruding or the pulse duct joint port. The invention has good joint performance, high precision of the product size, high production efficiency, lower pollution, convenient assemble and disassembly.

Description

technical field [0001] The invention relates to an insertion self-sealing pipe joint. The scope of application is the device for conveying water and steam, especially the parts of the water supply pipeline system. Background technique [0002] Ordinary pipe joints for connection are usually made of internal threads (pipe threads) at the joint port, and matching external threads are made at the ends of the pipes to be connected, so that the pipes with internal thread joints and external threads can be connected together . Since the pipe end threads are generally made at the installation site, thread tools must be prepared, and the pipe threads produced by general thread tools are relatively rough, and the resistance is very large when the pipe is screwed into the pipe joint. In addition, the pipe itself is round, and ordinary wrenches cannot be used. It is necessary to use a pipe wrench to kill the pipe body before installation. The whole process takes a lot of time and mo...
