Quick closing system

ExQuick opening cover design needs only one-eighth of a turn rotation for sealing. Ideal for high pressure operations requiring repetitive opening/closing. The "Clover Leaf" Closure Reactors provide maximum ease for quick opening or closing of the cover. The cover is simply inserted into the body and then rotated one-eighth of a turn. A safety locking pin is provided to insure that the cover is properly positioned and locked. One of the most difficult aspect is attaining continuous feed of the solids and continuous discharge at high pressure extraction vessels. Generally, the solid feed material is handled by using preloaded canisters. A quick opening closure that allows for rapid opening and closing is essential. Bolt closure is not safe and it takes a lot of time to open. On the other hand, cloverleaf cover opens in one second. If considered under the safety point of view, the cloverleaf cover offers three safety systems operating at the same time: 

  • The static pin. When the lid is in close position the operator introduces the safety pin in the vessel hole. Remove the pin to rotate the lid.
  • The dynamic pin. When the pressure build up in the vessel, the cover moves up and the dynamic pin goes in the safety hole in the cloverleaf upper side. When the pressure is completely removed, the lid will go down clearing the dynamic pin. Now the lid can rotate to open.
  • The electronic sensors control the correct position of the lid. If the sensors are not perfectly aligned, the process cannot start.
