My fourth uncle works as a pipe maintenance worker in the water plant. Therefore, I often follow him to the construction site or workshop during holidays. When I was playing, I often saw uncle workers who were installing and repairing pipeline equipment. Every time they installed the flange rubber sealing gasket, their fingers were either bruised or pricked by the flange equipment. What's more serious is that - according to my fourth uncle - last year, a master named Zhang Changhong had four fingers broken by flange equipment when installing pipe flange gaskets, causing his left hand to be disabled.
Gradually, I came up with the idea of ??inventing a flange rubber gasket so that it would not fall off or shift easily during installation and maintenance, but could be firmly attached. How great it would be to allow the master workers to completely avoid accidents such as pricking or breaking fingers!
When I was doing homework, a word problem stumped me. I thought about it and couldn't solve it. , what should I do? I picked up the plastic pencil box and played with it habitually by turning it on and off. Suddenly, a question popped up: What principle is used to open and close the pencil case? I looked carefully, looked again, and looked again. Oh, it turns out that the magnet is working. So, is it feasible to apply this principle to the installation and maintenance of flange gaskets on that pipe?
With the help of my uncle, I found flange rubber gaskets of various sizes and Remove magnets and other materials from old stationery boxes and try them on the pipe flanges. After many efforts and improvements, I finally succeeded! A magnetic rubber sealing gasket for flanges was born! I also applied for a national utility model patent and was approved (note application number: 2006200654680). If the factory can produce in large quantities, it will have a wide range of uses and can be used in water supply and drainage, petrochemical industry, farmland irrigation and other places where there are pipe flange gaskets. The workers will be safer and more at ease at work!
