ISO high-velocity relief valve fire resistance test is in progress, the test tank for combustible gases, and sustained combustion ten minutes later, the valve body temperature rises should be in line with standards. Stop burning, the valves to open and guide the flame shall not be extinguished. The flame must not pass into the tank valve, a return to burning.
ISO high-velocity relief ventilation valve by valve shell to protect exports, even valve burning mouth long time again, the valve will not be too high or stable. In the normal operating pressure, and its export flow rate more than 30 m/s, so the valve whether open or closed, the flame will not be liquid through the valve into the cargo hold.
ISO high-velocity relief valve fire resistance test, but also in a state of favor. Not just to pass the above tests, but also through the valve open and closed combustion test, test pressure tank for combustible gases, the flame with the valve open and closed and combustion and extinguished. In no less than 50 times and in the process after the cessation of 10 minutes, the pilot flame shall not be extinguished. Flame shall not through the valve port into the tank, a return to burning.
ISO high-velocity relief valve of imports (vacuum valve ) is conducting combustion test. Tank test within the combustible gases and combustible gases in plastic bagstogether Unicom (deflagration concentration and consistency) will be closed only in its anti-segregation. When the plastic combustible gas deflagration, not a string of anti-closed-combustible gas in the tank to burn.
ISO high-velocity relief valve closed basis for the IBC rules Chapter 6 of the requirements set up, when turned on the vacuum valve (liquid cargo imports), the outside world will never string of flame closed off access to the cargo hold of.
Our Company, Taixing Lanjie Shipping Safety Equipment is located in the south of the taixing city. By the changjiang River near Nanjing-Nantong Expressway and Jiangyin Bridge.
The company specially manufactures the marine safety equipment and fire extinguisher which was built in 90s.
Recently, The high velocity relief Valve which was researched and manufactured by itself. And filled the domestic gap. It was also built by our company firstly in China.
Marine Series high velocity Relief valve and laboratory for the high velocity relief valve was ratified by The China Classification Society and some foreign classification societies.
Our tenet is to contribute in the marine safety industry, create the A-class products and serve for all the customers. We also insist on quality comes first, safeguard our credit.
