    • A system and method for automatically controlling gas pressure for a plasma cutter includes a plasma torch, a gas supply system to provide a pressurized gas to the plasma torch, and a proportional valve configured to regulate the pressurized gas. The proportional valve includes a body, a valve seat positioned therein and defining a valve orifice, and a plunger having a mating surface on one end that mates with the valve seat and the orifice and a pressure receiving surface on an opposite end. The proportional valve also includes an inlet to receive the pressurized gas and distribute the pressurized gas to the valve orifice and the pressure receiving surface of the plunger, an electrical solenoid having a chamber to electro-magnetically translate the plunger therein, and a bias urging the plunger toward the valve orifice in conjunction with the pressurized gas when electrical power is reduced to the electrical solenoid.
    • 用于自动控制等离子体切割器的气体压力的系统和方法包括:等离子体焰炬,向等离子体焰炬提供加压气体的气体供应系统;以及配置成调节加压气体的比例阀。 比例阀包括主体,阀座位于其中并限定阀孔,以及柱塞,其一端上具有与阀座和孔口配合的配合表面,以及位于相对端的压力接收表面。 比例阀还包括用于接收加压气体并将加压气体分配到阀孔和柱塞的压力接收表面的入口,电磁螺线管具有用于将柱塞电动地平移到其中的腔室,并且施加偏压 当电功率降低到电磁线圈时,与加压气体相结合地朝向阀口的柱塞。
