噴、HIGH-VELOCITY RELIEF VALVE MONITOR EQUIPMENT

  

  Accrding to the rules of ISO 15364 and IMO.MSC/Circ, 677/Circ 1009, high-velocity relief valve has been tested and type approved while moving by Classification Soirety. Test iten as follows:
  a、Fire resistant and burnig again test.
  b、open and close pressure test.
  c、rate of flow and velocity of discharge test.
  d、corrosion-resistant and frostbite resistant test.
  e、pressure-resistant and airtight test.
  Each of the products is tested in the laboratory which is appointed by Administration Organ. Shipping Inspection certificate and each of the valve's test pressure, rate of flow chart and rate of flow collecting table under all kinds of pressure are offered to the ship owner by our manfacturing factory.
  The type approval test and factory leaving test of company'shigh-velocity relief valve are all carried out in Taixing Haixing High-velocity Relief Valve Inspection Center.

  
  ISO high-velocity relief air flow valve test is in progress, the test data collected automatically by the system. The trial must be vertical and inclined to the state.(See left)
  
  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.(See left)
  
  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.(See left)
  
  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.(See left)
  

  ISO high-velocity relief valve frozen test, even in-30≧ environment, the valve frozen thickness 20mm, the ISO high-velocity relief valve can also manually ice-breaking after normal work.(See left)
