Description

Screwed plug and clamp with same
Technical Field
The utility model belongs to the technical field of pipe fittings and joints, and particularly relates to a plug and a clamp with the plug.
Background
The plug is a component for plugging a pipeline or a clamp joint and generally comprises a plug body provided with a threaded section and a plug cap connected with the threaded section, wherein the threaded section is used for being in sealing fit with the inner wall surface of the pipeline or the clamp, and the plug cap is used for being in fit with the end surface of the pipeline or the clamp joint. A common plug structure is disclosed in the design patent with the publication number CN 306723411S.
However, when the plug with the structure is applied to high-voltage equipment conveying systems such as oil gas, chemical industry and the like, the plug is influenced by factors such as screw machining precision, part aging and the like, leakage phenomenon is easy to occur in a plug part in the actual use process, frequent plug overhaul and replacement are required, and a large amount of manpower and material resources are consumed. But also the leakage has the hidden trouble of polluting the environment.
To solve the leakage problem, a sealing ring is usually added between the thread section and the inner wall of the pipe or the clamp, or between the blocking cap and the end face of the pipe or the clamp to improve the sealing performance. However, the scheme of winding flexible bands on the thread segments is easy to cause expansion deformation of the pipeline or the clamp, and the practical effect is not ideal. The sealing ring is added on the end face of the plugging cap, so that the problem of radial leakage can be solved. In practice, however, leakage occurs first in the axial direction (i.e. the direction of flow of the material in the pipe), and if the problem of axial leakage cannot be solved, the solution of adding a sealing ring only at the end face is prone to failure.
