Hough section seal pad

Abstract

The invention belongs to the technical field of pipeline repair, particularly relates to a Hough section seal pad comprising a plug section which is in plugging matching with a pre-reserved groove on an outer shell body; the plug section is provided with a clamping point; and the clamping point is protruded on at least one side wall of the plug section. On one hand, the elastic supporting and clamping to the seal pad are realized through the elastic deformation of the clamping point, so that the effective fixed connection and matching to the Hough section shell body is ensured by the whole seal pad; on the other hand, the elasticity of the clamping point does not too obstruct the quick plugging and assembly between the seal pad and the outer shell body, so that the working efficiency is ensured; and the Hough section seal pad not only is applicable to the die-cast shell body, but also is generally applicable to existing shell bodies which are made through ordinary casting methods, and has a wider scope of application; and because the sealing performance can be kept unchanged and the manufacturing and processing procedures are reduced, the economic benefits of an enterprise can be effectively ensured.

Description

technical field [0001] The invention belongs to the technical field of pipeline emergency repair, and in particular relates to a half joint sealing gasket. Background technique [0002] The Huff Festival is a device for sealing and wrapping the leaking or damaged part of the pipeline to achieve rapid repair. Using this device can not only save the time of water stoppage, but also reduce the cost of repair, so it is widely used. In the existing half joint structure, adhesives are often used for the cooperation between the gasket and the half joint shell to ensure the structural stability during use. However, with the development of social technology With the progress, more and more technicians are more committed to the development of the non-adhesive fit structure between the gasket and the half joint shell, so as to reduce its manufacturing process and ensure its economic benefits while ensuring its structural stability. [0003] In view of the above situation, the applican...

AI Technical Summary

Problems solved by technology

Due to the die-casting structure of the shell, its surface is smooth and low in roughness, so when the gasket is directly embedded on it, the structural stability and sealing can be guaranteed through the plane contact between its sides. However, the above The defects of the structure itself cannot be ignored: First, the production cost is too high, because the shell must be molded by die-casting to ensure the low roughness of the surface, and the die-casting method is compared with the old-fashioned low-cost ordinary casting method , the production cost varies greatly, which often brings a large burden to the production budget of the enterprise; secondly, the application limitations are large, because the above structure is a flat contact snap fit, it can only be applied to die castings with low surface roughness , when it is directly copied to the ordinary casting, it is often because the surface contact and fit between the two cannot be effectively realized, resulting in a loose fit that causes the gasket to easily fall off, or a fit that is too tight. The phenomenon that the gasket cannot be installed normally
