What is the difference between self-closing valve of liquefied gas tank and ordinary valve?

The gas self-closing valve has no over-temperature protection function, and the over-current valve has no under-voltage function. Each has its own advantages, which is the difference between gas self-closing valve and gas overflow valve.

The gas self-closing valve is a multi-pole permanent magnet linkage mechanism, which magnetizes the permanent magnet material as permanent memory according to the design requirements, recognizes the change of gas pressure parameters passing through it, and automatically closes the valve and cuts off the gas source when it exceeds the safety set value. When the pipeline supplies air pressure. Gas relief valve, also known as "push multifunctional gas valve", is a patented product that works purely by machinery. The key technology is to push the push ring forward or backward by using the principle of magnetic characteristics of "like repulsion and opposite attraction", and at the same time, the switch is driven by the cooperation of magnetic force and spring recoil. Moreover, the more switching times, the better sealing performance and the longer service life of pipeline gas self-closing valve. The invention has the technical functions of no external leakage, over-temperature protection, over-current protection, over-voltage protection, convenient installation, energy saving and emission reduction.
