Product introduction: paddle wheel horizontal quick opening closure LSM paddle wheel horizontal quick opening closure (ZL03210870.2) uses coaxial double blind flange . Its blind flange shaft forward department keeps still and takes the advantage of the thrust of the Cant paddle rotation of the wheels of card board to push the front closure translational extrusion seals. It ensures closure and no relative movement between the seals and avoids the blind plate and the seal friction, resulting in seal is damaged. In addition, the wheel paddle fast-opening blind also has a secondary pressure relief and safety interlock (shockproof, prevent loose) function, when the cylinder body with pressure, blind plate could not be opened, make sure the safety of operation. Design features: 1. Simple structure and quick switch Structure simple, only when the switch will wheel to wheel is sunken place, using a wrench, rotating screw 90-720 ° ensures that an operator in the case of don't need any special tools, a minute to open the blind plate, safety, no leakage 2. Coaxial double plate and translational seal Since fast-opening blind rotating parts and sealing for coaxial double plate, the rotation of the card board with its incline to the front axle to thrust, promote blind flange translational displacement forward, make the sealing ring by extrusion, so as to achieve the translational seal, the seal without any damage 3. Linkage lock, safe and reliable Closed in place (safety interlock mechanism can't load), loading safety interlock, satisfied all on scheduled operating position can lock the rear booster, otherwise can't booster. Safety interlock mechanism after loading, cranium cannot turn; System after discharge, you must first open the safety interlock device, make the container internal pressure all after discharge, cranial open: action to take, otherwise unable to open the cranium
