The design necessity of two pressure relief valves in the lock cylinder
Thread Content
For a gasification furnace of 65 kilograms, let’s discuss this: designing two pressure relief valves is a good approach. Let’s talk about the necessity.
The hopper pressure relief valve is a valve that operates under extremely harsh conditions; the vibrations that occur during the operation of the hopper are one of the sources of vibration for this valve. The lock hopper releases pressure every half hour or so, and the medium involved is water with a high solid content. Such frequent pressure releases, along with the harsh conditions of this medium, pose a significant challenge to the sealing performance of the lock hopper’s pressure release valve. With the pressure difference before and after the pressure relief valve reaching up to 65 kilograms, it is necessary to install two pressure relief valves here for operational safety reasons. After all, safety in chemical production is of the utmost importance. A pressure relief valve costs only a few hundred thousand to two million yuan, yet it can minimize the safety risks present in that area. It’s like buying insurance: you might not encounter any problems during the coverage period, in which case the money spent on insurance is wasted. But if something does happen, that premium can truly be a lifesaver.
If improvements can be made to the coal powder conveying process, then two lockhopper pressure relief valves might not be necessary.
Many manufacturers offer just one type of valve; the price of such valves in China is over 30,000 yuan, and their lifespan is generally around one year. Two valves – in fact, it seems that their function is no different from that of a single valve

Indeed, there isn’t much difference in usage between two valves and one valve, so most systems use just one valve. As I said above, those two valves are like buying insurance
The design of a lockout pressure relief valve typically includes a shut-off valve and a control valve, which enables effective control of the pressure release rate and provides good protection for both the valves and the pipelines. Using two shut-off valves is a precaution from a safety perspective; the conditions behind the pressure relief valve are very harsh, so having two valves in place is also a good idea, as it enhances safety.
