A long-term stainless steel pipe sealing joint

Abstract

The invention discloses a long-acting stainless steel pipe sealing joint, which belongs to the field of pipe joints. It is a long-acting stainless steel pipe sealing joint. Through the setting of pre-sealed undulating pipes, during installation, the extrusion effect on the end of the stainless steel pipe Next, the pre-breaking magnetic rod is broken, the sealant in the overflow ring is released, and it overflows quickly, and the steel pipe is rotated to disperse evenly, thereby forming a layer of sealing barrier in the stainless steel pipe, and then through the liquid injected into the liquid injection port The rubber liquid, after solidification, forms a sealing layer that is integrated with the joint body between the end of the stainless steel pipe and the joint body, and becomes another layer of sealing barrier that is not extruded by the stainless steel pipe or subjected to little force. Compared with the existing technology, it significantly prolongs the sealing time and reduces the maintenance frequency. In addition, when in use, the undulating structure of the pre-sealed undulating tube can buffer the hydraulic pressure to a certain extent, improve the stability of the hydraulic pressure at the joint, and reduce the impact of the hydraulic pressure on the sealing layer. Intensity of influence.

Description

technical field [0001] The invention relates to the field of pipe joints, in particular to a long-lasting stainless steel pipe sealing joint. Background technique [0002] Stainless steel pipe is a hollow long round steel, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. [0003] In the prior art, the connection between the stainless steel pipe and the pipe joint is generally reinforced and sealed by a pipe collar, and then the surface is coated with sealant to improve the sealing of the joint of the stainless steel pipe. However, this method is complex in operation and low in installation efficiency. , on the other hand, the inner gasket used for sealing is always in a state of being squeezed, causing it to crack and age easily. In this case, the internal fluid hydraulic pressure is small, and its effective sealing time is relatively short, resulting in l...

[0003] In the prior art, the connection between the stainless steel pipe and the pipe joint is generally reinforced and sealed by a pipe collar, and then the surface is coated with sealant to improve the sealing of the joint of the stainless steel pipe. However, this method is complex in operation and low in installation efficiency. , on the other hand, the inner gasket used for sealing is always in a state of being squeezed, causing it to crack and age easily. In this case, the internal fluid hydraulic pressure is small, and its effective sealing time is relatively short, resulting in later Prone to water seepage, high maintenance frequency
