Easy-to-disassemble high-sealing movable joint and use method thereof

Abstract

The invention discloses an easy-to-disassemble high-sealing movable joint and a use method thereof. The easy-to-disassemble high-sealing movable joint comprises a first movable joint body, a first protective sleeve, a first connecting opening, a connecting groove, a check ring, a second protective sleeve, a connecting sleeve, a second movable joint body, a threaded connecting opening, a second connector, a nut and a first connector; a check block is fixedly connected to one side of an inner cavity of the nut, a check ring is arranged at the inner cavity of the nut, a layer of protective pad isbonded to the inner wall of the check ring, and one end of the second movable joint sequentially penetrates through the check ring and the threaded connecting opening to extend out of the inner cavity of the nut; the surface of one end of the second movable joint is sleeved with a connecting sleeve, the top of the connecting part of the connecting sleeve and the threaded connecting opening is sleeved with a second protective sleeve, a circle of second fireproof ring and a second sealing ring are sequentially arranged at the inner side of the second sealing ring from left to side, and the inner sides of the second sealing ring and the second fireproof ring are all attached to the surface of the second movable joint. The invention provides an easy-to-disassemble high-sealing-performance movable joint with a good protection effect and a use method thereof.

Description

technical field [0001] The invention relates to a movable joint and its use method, in particular to an easy-to-detachable high-tightness joint and its use method. Background technique [0002] The union, also known as union or union, is a common pipe connector that can be easily installed and disassembled. It mainly consists of three parts: nut, cloud head and butt joint. The pipe connectors machined by round steel or steel ingot die forging, its connection form is divided into socket welding and threaded connection, socket welding is to insert the steel pipe into the socket hole for welding, so it is called "socket welding". The threaded connection is to screw the steel pipe into the screw hole for connection, so it is called "threaded union", [0003] The general union only has three parts: nut, cloud head and flat joint. Although the installation and disassembly are simple, the sealing performance is average. Leakage may occur when connecting pipes. Moreover, the protec...
