Valve leakage and conforms to the ANSIB16.104 standard, valve equipped with multi spring actuator different, large output force.
这意味着操作机构必须离阀门足够远以允许阀门通过气门弹簧使其完全关闭。
This means that the operating mechanism must be able to move sufficiently far enough away from the valve to allow the valves to be fully closed against its seat by the valve spring.
由于弹簧材料钢性大不能用不锈钢球阀等防腐材料制作，产品防腐能力差，阀门的使用寿命不长。
As the largest steel spring material such as stainless steel anti-corrosion materials can not be produced, poor corrosion products, the life of the valve is not long.
调整阀门的弹簧压力大小，应通过试灌装计量及操作人员的经验来确定。
The switching speed increases with the spring force. The adjustment of the spring force of the valves shall be determined by trial filing metering and the experience of operator.
液体从系统中被排出时，系统压力降低，直到在弹簧压力作用下阀门回复原位。
As fluid is released the system pressure decreases until the spring force re-seats the poppet.
弹簧受压差的作用自动控制阀胆上过流面积的大小，从而使通过阀门的流量恒定。
The role of compression springs bad gall on automatic control valve flow area of the size, so that a constant flow through the valve.
这种阀门应该是黄铜阀体，不锈钢阀杆和弹簧。
Valve shall have a brass body and stainless steel stem and spring.
当阀门出口压力降到导阀弹簧设定压力时，导阀开启，控制室向下游排水。
When the valve outlet pressure to a pilot valve spring set pressure, pilot valve opens, the control room to the downstream drainage.
春季返回气动执行机构使用的空气供应，以推动一个方向阀杆和一个内部装载弹簧返回到原来的位置阀门。
The spring return pneumatic actuators use an air supply to drive the valve stem in one direction and an internally loaded spring to return to the valve to its original position.
断电时，辅阀利用弹簧力或介质压力推动关闭件，向下移动便阀门关闭。
The high pressure around the valve off, fluid pressure to promote the closure of parts moving down, close the valve.
有些类型止回阀配置弹簧驱动，能够在流动停止时，立即关闭阀门。
