The structure of the SC cylinder valves

SC cylinder vacuum valve cylinder structure parsing SC in the valve body cavity in the open position and close up from his seat in the closed position on the seat between adjustment, in the open position the main flow path by vacuum valve opening, in the closed position by vacuum valve to close the main flow path, the main blocking artifacts have additional flow path through the inner cavity and flow path of the additional seat in additional. Have additional blocking artifacts, its can be in the inner cavity of primary closure components from the additional seat lift of the open position and close to the additional seat in the closed position adjustment, flow path in the open position attached by the vacuum valve opening, in the closed position by vacuum valve to close the additional flow path, flow path through the main blocking artifacts and additional variable between additional blocking artifacts in the middle of the cavity, its size can be relative to the main blocking artifacts rotation additional locking component change. SC cylinder cylinder sealing membrane, the product of the sealing membrane attached to the flexible membrane and the basement and cover products flexible membrane between the hole; And flexible membrane products, through the use of adhesive layer, flexible membrane is attached to the product of the seal on the surface of membrane and product of basement, the product of the flexible membrane can be moved to the open position, and when the product of the flexible membrane in the open position, attached to the product of the flexible membrane products sealing membrane makes the product of open hole, and the sealing film and in the products formed between the base of air passage, and makes the air through it.
