Safety relief valve: The safety relief valve plays a safety protection role in the system. When the system pressure exceeds the specified value, the safety valve is opened, and a part of the gas in the system is discharged into the atmosphere, so that the system pressure does not exceed the allowable value, so as to ensure that the system does not occur due to high pressure accidents. The main parameter of the safety relief valve is the displacement, which is determined by the diameter of the valve seat and the opening height of the valve disc, by the opening height is different, and it is divided into two kinds of micro-opening and full opening. Micro-opening means that the opening height of the valve disc is 1/40 ~ l / 20 of the throat diameter of the valve seat. Full opening means that the opening height of the valve disc is 1/4 of the throat diameter of the valve seat. The safety relief valve is suitable for urban construction, chemical industry, metallurgy, petroleum, pharmaceutical, food, beverage and environmental protection| Safety relief valve model: AY42H, YA802Y | Nominal diameter of safety relief valve: 15MM-40MM | The use pressure of safety relief valve: 16MPA-60MPA |
