双球润滑油注入器
DOUBLE BALL GREASE INJECTOR

　　美国太平洋阀门独特的注入器具有双球止回保护，防止泄露，并保护阀门内部活动部件。在注入润滑油之前，注入器圆头螺栓必须拧松半圈，打开阀门内部部件通道。在拧松注入器圆头螺栓时，要用第二个扳手固定住注入器，防止其从主阀门上松落下来。在润滑油注入后，重新旋紧头部，保持关闭状态。
　　Pacific Valves' unique injector has a double ball check protection against leakage and a positive shut-off internal valve. The injector button head must be unscrewed one half turn to open the internal valve before injecting grease. While unscrewing the injector button head, a second wrench must be used to assure that the injector body is not loosened from the main valve. After grease injection the head is then retightened to maintain positive shut-off.
