Embodiment Construction

[0008] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0009] Such as figure 1 As shown, the embodiment of the present invention provides a pipe joint of a coal slag conveying pipeline in a power plant, which is composed of a pipe joint body 1 and an outer cylinder body 2. The pipe joint body has an inner sleeve part 3, and the inner sleeve part has an independent protrusion 4. There is an internal thread protrusion on the outer cylinder, and the outer cylinder forms a spiral groove on the outer peripheral surface of the pipe and advances in a spiral, and is combined with the pipe joint body in a final tightened state.

[0010] The beneficial effects of above-mentioned technical scheme of the present invention are as follows:

[0011] In the above solution, the present invention can fully withstand the pull...

Abstract

The invention discloses a power plant coal slag conveying pipeline connector which is composed of a pipe connector body and an outer cylinder body. The pipe connector body is provided with an inner insertion cylinder part which is provided with an independent protruding bar. The outer cylinder body is provided with an inner thread protruding bar. A spiral groove is formed in the outer circumferential face of a pipeline by the outer cylinder and advances in a spiral manner, and the spiral groove is combined with the pipe connector body in a final fastened state. In the above scheme, the drawing force of the pipeline can be tolerated sufficiently in the situation that the number of parts is relatively small, and the stable sealing performance can be achieved. In addition, connection work can be simply conducted with commonly-used work tools such as a wrench.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to a pipe joint of a coal slag conveying pipeline in a power plant. Background technique [0002] The pipe joints of the coal slag conveying pipelines in the prior art have poor assembly strength, low service life, low reliability in use, convenient disassembly when maintenance is required, and unsatisfactory sealing performance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pipe joint for coal slag conveying pipeline in a power plant to solve the above technical problem. [0004] In order to solve the above technical problems, an embodiment of the present invention provides a pipe joint of a coal slag conveying pipeline in a power plant, which is composed of a pipe joint body and an outer cylinder. There is an internal thread protrusion on the outer cylinder, and the outer cylinder forms a spiral groove on...
