PDF《Operation 减压阀的选择、安装和操作》

Specialty Gas and Equipment Catalog, which lists the proper regulator for almost every gas, pressure, and situation. Simply look up the gas or mixture for your application and you will find the appropriate regulator listed under Recommended Equipment. CGA valve outlets are also noted for each gas and gas mixture. The regulator must be equipped with the appropriate CGA connection for the cylinder valve outlet. 为了让你的选择更容易, 请参考Air Products的 特种气体和设备目录 . 它列出了几乎所有气体、 压力和场合下的合适的调整器.仅仅查找用于你的应用的气体或混合物,你就会找到列于 推荐 设备 下的合适的调整器.对于每种气体和气体混合物还附注了CGA的阀门排气口.调整器必须 配备有用于钢瓶阀门排气口的合适的CGA接头. Putting the Regulator into Service 把减压器用于设施 1. Identify the regulator. Check the label and the inlet and outlet gauges. Ascertain that the high-pressure gauge is suitable for the pressure of the cylinder or source system.鉴别减压器.检查商标和入口和出口的量表.确定高压量表对钢瓶或源系统是适合的. 2. Inspect the regulator. Check the regulator for evidence of damage or contamination. If there is evidence of physical damage or foreign material inside the regulator, contact your customer service representative for return or repair information.检查减压器.检查调整器是否有损伤或污染的迹象.如果有物理损伤的迹象或内 部有不相干的物质,联系你的用户服务代表,以得到返还或维修的信息. 3. Inspect the cylinder valve. Check the cylinder valve for evidence of damage or contamination. Remove any foreign material before attaching the regulator.检查钢 瓶阀门.检查钢瓶阀门是否有损伤或污染的迹象.再连接调整器之前,排除任何不相干的物质. 4. Attach the regulator. Fasten the regulator to the cylinder and tighten the inlet nut securely.连接减压器.把调整器紧固在钢瓶上,安全地上紧入口螺母. 5. Close the regulator. To close the regulator, turn the adjusting knob to the full counter-clockwise position. The regulator must be closed before opening the cylinder valve.关闭减压器.要关闭减压器,把调整钮逆时针旋死.在开启钢瓶阀门之前,必 须关闭减压器. Safety-Checking the System 系统的安全检查 With the regulator adjusting knob turned fully counterclockwise, place both hands on the cylinder valve and open it slowly, allowing the pressure to rise gradually in the regulator. Stand as shown (see Fig. 2) with the cylinder valve between you and the regulator. When the high-pressure gauge indicates maximum pressure, open the cylinder valve fully. 减压器的调节钮逆时针旋死后,两只手放在钢瓶阀门上,慢慢地开启,使减压器内的压力逐渐增 加.站得使钢瓶阀门在你和减压器之间.当高压量表指示为最大压力时,彻底打开钢瓶阀门. Always close the cylinder valve when product delivery is not needed. Do not leave it open when the equipment is unattended or not operating. 当不需要产品输出时,总是关闭钢瓶阀门.当设备无人照管或没有运转时,不要让阀门开着. Adjusting the Pressure 调整压力 Turn the adjusting knob clockwise and establish the required use pressure by referring to the low-pressure gauge. Make sure that the cylinder valve is easily accessible.] 顺时针旋转调整钮,通过查看低压量表建立要求的使用压力.确认钢瓶阀门容易接近. Precautionary Measures 防范措施 ?Never exchange the discharge (low-pressure) gauge for one of lower pressure. The gauge may rupture if the adjusting knob is unintentionally turned too far.禁止把排 出量表换成更低压力的量表.如果无意中把调整钮旋的太远的话,量表会破裂. ?Check diaphragm regulators for creep (leakage of gas from the high-pressure to the low-pressure side when the adjusting knob is turned fully counterclockwise).检 查隔膜减压器是否有漂移 (如果调整钮逆时针方向旋死的话........
