常用油桶一般采用螺旋式节门,由于关闭慢,容易造成滴漏现象。改用快关油嘴(如图)可以代替螺旋式节门,克服上述缺点。使用时将阀体的G1/2″螺纹,旋入油桶的接头内,用螺母调整弹簧的压力,使阀杆处在不松不紧的状态,便于移动开启或关闭。阀杆的90°锥部与阀体φ12孔接触,并经研合,保证不漏油。在正常状态下由于弹簧的作用,阀孔处于关 Commonly used oil drums commonly used spiral section door, due to slow closure, easy to cause drip phenomenon. Switch to fast-closing nozzle (pictured) can replace the spiral door, to overcome the above shortcomings. Use the body of the G1 / 2 "thread, screwed into the barrel joint, with a nut to adjust the pressure of the spring, so that the valve stem is not loose not tight state, easy to move open or close. 90 ° valve stem Cone Department and body φ12 hole contact, and the research, to ensure no oil leakage in the normal state due to the role of the spring, the valve hole is off
