A pipe fitting sealing connection structure and its connection and disassembly method

Abstract

The invention provides a pipe fitting sealing connection structure as well as a connecting and dismounting method thereof, and belongs to the field of pipe fittings. The pipe fitting sealing connection structure solves the problem that an existing pipe fitting is poor in sealing performance. The pipe fitting sealing connection structure comprises two pipe fittings and a sealing connection device,wherein the sealing connecting device comprises a first sealing connecting mechanism and a second sealing connecting mechanism; the first sealing connecting mechanism comprises an inner connecting sleeve and two outer connecting sleeves, the outer ends of the two outer connecting sleeves are connected to the two ends of the inner connecting sleeve, the outer wall of each outer connecting sleeve isprovided with a sealing groove, and a sealing ring sleeves in the corresponding sealing groove; the second sealing connecting mechanism comprises an inner adjusting sleeve and two outer adjusting sleeves, wherein the inner adjusting sleeve sleeves the inner connecting sleeve, and the two outer adjusting sleeves are connected to the outer wall of the inner adjusting sleeve in a threaded mode, a connecting hole is formed in each outer connecting sleeve, a pin sleeve is fixed to the outer wall of each outer adjusting sleeve, a pin hole is formed in each pin sleeve, and a pin column is embedded in the corresponding pin hole; and a pin groove is formed in the inner wall of each pipe fitting, two check rings are arranged on the outer wall of the inner adjusting sleeve, and sealing sleeves are arranged on the inner adjusting sleeve in a sleeving mode. The connecting structure can be used for sealing and connecting pipe fittings in a high-strength mode.

Problems solved by technology

[0002] During the construction of pipe fittings, it is often necessary to seal and connect two pipe fittings. At present, most of them are threaded and fixed with glue, but the strength is low and the sealing performance is poor. If fasteners are used to connect, although the connection strength can be significantly improved , but the fastener will pass through the pipe, and the fluid in the pipe will easily leak along the fastener penetration part, resulting in poor sealing, and no matter what method is used to connect, the two pipes to be connected will surround the If the other end of some pipe fittings has been connected with other devices, it must be ensured that the pipe fittings cannot rotate around their own axis during the connection process. Therefore, the above connection methods are not suitable for pipe fittings of this structure, and the traditional connection devices are in the After connecting two pipe fittings, the joint will protrude from the outside of the pipe fittings and cannot be inserted into the pre-opened pipe holes. Therefore, it is necessary to design a connection structure that can quickly locate and connect two pipe fittings and improve the sealing strength of the joint parts.
