AY42H, YA802Y safety relief valve
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 valve main points of order
Safety valve medium, pressure level, opening mode (full opening/micro opening) set the take-off pressure, determine the valve size, connection mode, standard maximum temperature resistance, release flow/hour, valve body material, internal valve body structure, working principle, installation instructions and other related technical data. Safety valve selection is mainly based on (take-off pressure and neat pressure flow temperature) caliber general design institute will be given, and in fact through the steam pressure, flow and take-off pressure, you can infer the size of the safety valve. Generally, it will be smaller than the caliber selected by the design institute. When the occasion is very important or the environment is more complex, please try your best to provide design drawings and detailed parameters, by our Xuan Cheng valve company experts for your review.
