How to realize good explosion-proof performance of liquid ammonia emergency shut-off valve?

time:2021/9/3from:Hangzhou Kaiwei Valve Group Co., LTD

In recent years, the sales volume of liquid ammonia emergency shut-off valve shows the trend of high-speed explosion, and its application scope covers many different fields such as mining, petroleum, chemical industry and so on. The following briefly introduces how to achieve good explosion-proof performance of liquid ammonia emergency shut-off valve:


1、The shell material has the explosion-proof effect of gas explosion pressure

Compared with other types of solenoid valves, liquid ammonia emergency shut-off valve has better explosion-proof performance because its shell material has the explosion-proof effect of gas explosion pressure. Most shell materials are made of metal frame and flame retardant and high temperature resistant resin. These two materials play a very important role in improving the explosion bearing capacity of the shell.


2、It reduces the energy transmission of gas explosion and has a certain blocking effect

When the liquid ammonia emergency shut-off valve is energized, a certain electromagnetic force will be generated, and the magnet coil will be attracted to different positions. This design is equivalent to controlling the mechanical movement of the electromagnet by controlling the current of the electromagnet, so as to reduce the energy transmission of gas explosion and have a certain blocking effect.


3、Install all components with explosion-proof function into the flameproof enclosure

The explosion-proof shell of the liquid ammonia emergency shut-off valve separates the internal space of the valve from the surrounding environment. In order to avoid the impact of the liquid ammonia emergency shut-off valve on the surrounding explosive gas mixture when moving, the reason for its good explosion-proof performance is to put the parts prone to spark, arc and dangerous temperature into the explosion-proof shell, so as to reduce the probability of explosion.

The upgrading and innovation of liquid ammonia emergency shut-off valve is refreshing. The understanding of the function of the original solenoid valve also urges more and more people to consult the high-frequency service of liquid ammonia emergency shut-off valve. According to the relevant feedback, the explosion-proof performance of liquid ammonia emergency shut-off valve is good, not only because the shell material has the explosion-proof effect of gas explosion pressure, but also because it can reduce the energy transmission of gas explosion, It has a certain barrier effect, and all components with explosion-proof function are installed in the explosion-proof shell.
