Speaking of safety valves, in fact, many people are familiar with it, it is a very important safety accessory for boilers, pressure vessels and some pressure equipment. It has a very important role in our lives, today I will introduce you to the relevant content about the safety valve, I hope it will be helpful to you.

Clause.

First, the basic content of the safety valve

The safety valve not only has the role of a switch, but more importantly, it plays a protective role in the safety of the equipment, with more and more equipment items with pressure control, the safety valve, so it also plays a vital role in the process of protecting the equipment. When the pressure of the equipment rises to a predetermined value, in order to prevent the pressure of the equipment from continuing to rise, the safety valve will be automatically opened to relieve the pressure; When the pressure drops to the specified value, in order to prevent a large amount of media from being lost in the equipment, the safety valve will be automatically closed. Safety valves are of great significance to our life and work, and play a protective role in the safety of our personal and property safety and equipment operation.
