At the end of valve should be installed in the pump suction pipe at the Bellow Seal Valve bottom.

底阀应安装在水泵吸水管路的底端。

Valve steam stop, it should exclude condensate.

汽阀停汽后，也要排除凝结水。

The combination of steam and water is still being released through the PORV.

水和蒸汽的混合物仍然通过释压阀排放。

Whev the steam evters the ball ivside,the ball bring buoyancy and floating valve port,close valve port The ivside steam of the ball congealed and lost the buoyancy,moves to the bottom,At the same time opev valve port,eject the coagulative water quickly.

当蒸汽进入球桶内，球桶产生浮力并漂向阀口，关闭阀门。球桶内的蒸汽冷凝后失去浮力后往下移，同时开启阀门，迅速排出凝结水。

NOTE: When regulator is installed above the line or in a veritcal line on steam service, the control pipe must have a loop to form a water seal to prevent steam from contacting the diaphragm.

注：如果调节阀安装在蒸汽系统中的管道上方或垂直管道上，则控制阀必须有一个回路形成水密封，以防止蒸汽接触到隔膜。

When the device has just started, low-temperature condensed water pipe occurs, double metal film is flat, the spool of elastic in the spring, the valve in the open position.

当装置刚启动时，管道出现低温冷凝水，双金属片是平展的，阀芯在弹簧的弹力下，阀门处于开启位置。

When the device just starting when the low-temperature condensed water pipe occurs, double metal film is flat, and the elastic spring heart valve, the valve in the open position.

当装置刚起动时，管道出现低温冷凝水，双金属片是平展的，阀心在弹簧的弹力下，阀门处于开启位置。
