AI Technical Summary
Technical Problem
Existing filled steel cylinders are prone to excessive gas during the filling process, which can lead to internal rupture and expansion, reducing safety and lifespan.
Method used
An overfill prevention gas cylinder was designed. By setting a first piston and a second piston in the air inlet pipe, the gas pressure is used to automatically seal the air inlet pipe to prevent overfilling. The limiting ring and sealing structure ensure that the gas inside the gas cylinder does not overflow.
Benefits of technology
It effectively prevents overfilling of gas cylinders, improves safety, extends the service life of gas cylinders, and avoids damage caused by overfilling.

Abstract
The utility model discloses a kind of overcharge prevention steel cylinders, relate to the technical field of filling steel cylinder, solve the filling steel cylinder when gas is filled, it is easy to cause the gas filled in steel cylinder too much, and after the overloading of gas is filled many times, it is easy to cause the internal rupture of steel cylinder, cause expansion, cause steel cylinder damage, reduce the security when steel cylinder is used, and make the service life of steel cylinder shorten Problem, including steel cylinder and gas inlet pipe, the gas inlet pipe is fixedly installed in the upper end of steel cylinder, and is communicated with the inside of steel cylinder, the inside of the gas inlet pipe is slidably connected with first piston and second piston respectively, a plurality of connecting columns are fixedly installed between the first piston and the second piston with equal intervals, by the first piston and the second piston set, after the gas in steel cylinder is filled, because internal pressure is too large, first piston is extruded upwards, gas inlet pipe can be conveniently sealed, effectively prevent the air intake work of air inlet threaded pipe.
