Problems solved by technology

The ferrule joint in the prior art includes a ferrule and a pressure cap. When in use, the ferrule and the pressure cap are sequentially inserted onto the pipe fittings to be connected, and then the pipe fittings are connected to the pipe joint through the ferrule and the pressure cap. However, due to the split structure of the pressure cap and the ferrule, and the small size of the ferrule, they need to be placed and carried separately. In the process of actual use, the pressure cap or ferrule is easy to lose when placed and carried, which makes it impossible to install on site. At the same time, two steps are required for installation, and the installation efficiency is easily affected by factors such as the proficiency of the installer, the field installation environment, and the processing quality of the ferrule and the pressure cap, resulting in low installation efficiency; moreover, due to the ferrule and the pressure cap It is processed separately, and the processing accuracy has a great influence on the connection stability, which makes the connection of this ferrule joint unreliable and easy to leak.

Abstract

The invention discloses an integral ferrule joint. The integral ferrule joint comprises a ferrule (1) and a pressing cap (2), wherein the pressing cap (2) is partitioned into a threaded portion (2.1) and a spanner clamping portion (2.2); the ferrule (1) is connected to the threaded portion (2.1) and far away from the end of the spanner clamping portion (2.2); the axis of the ferrule (1) and the axis of the threaded portion (2.1) are on the same straight line, and the ferrule (1) is integrated with the threaded portion (2.1); the cross section of the ferrule (1) has a trapezoidal structure, and the inner surface of the ferrule (1) corresponds to the lower side of the trapezoidal structure. Compared with the prior art, the integral ferrule joint has the characteristics of prevention of losing since the pressing cap and the ferrule can be placed and carried as an integral structure, high mounting efficiency, high connecting reliability and prevention of leakage.

Description

technical field [0001] The invention belongs to the technical field of connection joints, in particular to an integral ferrule joint used for pipeline connection. Background technique [0002] At present, when connecting low-pressure gas pipelines, the general method is to use (spherical or conical) ferrule connection. The ferrule joint in the prior art includes a ferrule and a pressure cap. When in use, the ferrule and the pressure cap are sequentially inserted onto the pipe fittings to be connected, and then the pipe fittings are connected to the pipe joint through the ferrule and the pressure cap. However, due to the split structure of the pressure cap and the ferrule, and the small size of the ferrule, they need to be placed and carried separately. In the process of actual use, the pressure cap or ferrule is easy to lose when placed and carried, which makes it impossible to install on site. At the same time, two steps are required for installation, and the installation ...
