The outlet of the safety valve on the steam boiler must be equipped with a silencer.* * Are there specific requirements in standards or specifications?
I’ve never seen the specification, I’ve never even heard of it. I searched on Baidu and found out that this thing actually exists, but I feel strange why is this thing installed on the outlet of the safety valve? Could it be that your safety valve is over-pressurizing and exhausting all day long? I wonder if it will affect the emergency use of the safety valve? Generally speaking, it is enough that the noise standards meet the noise hygiene standards of industrial enterprises.
There should be no security requirements. From a security perspective, installation should not be allowed. There may be requirements for environmental protection and occupational hygiene. I'll check.
Generally, installation is not allowed. Pressure relief must be smooth. Installing a silencer will suppress the pressure. If the pressure is not released in time, it will not be smooth.
After carefully reading the "Design Hygienic Standards for Industrial Enterprises", "Safety and Hygiene Design Regulations for Chemical Enterprises", "Design Specifications for Occupational Safety and Health for Petrochemical Enterprises", "Design Specifications for Noise Control of Industrial Enterprises" and "Boundary Noise Standards for Industrial Enterprises", there are no specific requirements for the noise generated by safety valves. The noise of the safety valve is generated under specific circumstances. When a real accident occurs, its noise is needed^_^Compared with other safety requirements, that noise is basically negligible. Please give some advice:handshake
After reading the discussion speeches above, I am very grateful to everyone and thank you for your selfless help. I will try my best.
No, just use one with good noise reduction effect, but the price is different.
I’ve never heard of it! None of our company’s safety valves are installed! Generally, steam will not be thrown away, and it is rarely used with overpressure!
A silencer needs to be designed because once the safety valve trips, the noise will be very loud and affect the environment.

Recently, during the inspection of our company's air compressor station, the Work Safety Supervision Bureau proposed that the exhaust pipe of the safety valve should be led outside or add silencer facilities. It is said that there are regulations, but it is not for safety and occupational health.
unnecessary! The sound of the safety valve can serve as an early warning, but after it is installed, it will have no prompting effect! Never sacrifice safety at any time!
