氧气截止阀安装、使用、维护注意事项

译文：
1、安装时注意阀体上箭头方向应与介质流动方向一致。 2、将导线拧在两侧法兰的接地螺栓上，并将其接地，导除阀门上内的静电。 3、操作阀门时手轮顺时针旋转阀门关闭，逆时针旋转阀门开启。对带有内旁通结构的氧气阀开启时，先逆时针旋转手轮打开副阀瓣，待阀门前后压力差减小到0．3MPa时，再继续旋转手轮打开主阀；对带有外旁通阀的氧气阀开启时， 首先打开旁通阀，待阀门前后压力差减小到0．3MPa时，再打开主阀。关闭时先关主阀后关旁通阀。 4、该阀为全关、全开型。操作时应缓慢进行，并不得当调节阀用。 5、维护时传动部位涂不可燃的润滑脂。 6、其余事项按冶金工业部《氧气安全规程》和《钢铁企业氧气管网若干技术规定》执行。

1, the installation direction of the arrow on the valve body when the note should be consistent with the medium flow direction. 2, will lead screw on both sides of the flange bolts on the ground, and its grounding, guided addition toFlanged end pressure-seal globe valve the electrostatic valve on the inside. 3, the operation when the valve hand wheel clockwise the valve closed, counterclockwise rotation of the valve to open. Right with the structure of the oxygen inside the bypass valve is turned on, counterclockwise rotation of hand wheel to open the first Vice-valve valve, the pressure difference before and after the valve to be reducedANSI More arrangement bellows globe valveto 0.3MPa, when, and then continue to rotate hand wheel to open the main valve; right with the oxygen outside the bypass valve when the valve is open, first open the bypass valve until the pressure difference before and after the valve, when reduced to 0.3MPa, and then open the main valve. First off the main valve is closed off after the bypass valve. 4, the valve is fully closed, fully open-type. Operation should be carried out slowly and does not properlyBellows gate valve regulating valve. 5, when the transmission parts to maintain the grease coated non-combustible. 6, the remaining items according to Ministry of Metallurgical Industry, "Oxygen Safety Regulations" and "iron and steel enterprises a number of technical requirements for oxygen pipeline," implementation.
