出口压力达不到设定压力 1． 产品出厂时，没有调节设定压力 2． 滑行部位不圆滑。 1． 按第六项调节压力 2． 分解后，用超细砂纸磨阀杆导向座及阀座密封部位。 出口压力超过设定压力 1． 阀门主要部位(阀瓣及阀座)上夹异物或凹陷。 2． 阀座及导向部位的O型圈被破坏。 3． 隔膜被破损(弹簧盖部分进水) 4． 出口感应孔被堵。 1． 分解后除去异物，不可能时研磨或更换。 2． 分解后更换O型圈。 3． 分解后更换隔膜。 4． 分解后通孔。 阀体部位有液体泄漏 1．阀体上的排气阀被松开或破损，堵上的垫圈破损。 1． 拧紧松开部位，更换破损部件。 震动或噪音 1．使用液体时隔膜压力腔发生气体。 1．利用空气塞，除去隔膜腔内的空气。 (1) 调压范围：它是指减压阀输出压力P2的可调范围，在此范围内要求达到规定的精度。调压范围主要与调压弹簧的刚度有关。 (2) 压力特性：它是指流量g为定值时，因输入压力波动而引起输出压力波动的特性。输出压力波动越小，减压阀的特性越好。输出压力必须低于输入压力—定值才基本上不随输入压力变化而变化。 (3) 流量特性：它是指输入压力—定时，输出压力随输出流量g的变化而变化的持性。当流量g发生变化时，输出压力的变化越小越好。一般输出压力越低，它随输出流量的变化波动就越小。

Steam valve failure causes and measures Outlet pressure of less than the set pressure 1. The factory, there is no pressure regulator setting 2. Parts do not slide smooth. 1. Adjust the pressure according to the sixth 2. Decomposition, with a fine sandpaper grinding seat and seat guide stem seal area. Outlet pressure exceeds the set pressure 1. Main parts of the valve (the valve flap and valve seat) folder on foreign or depression. 2. Oriented parts of the valve seat and O-ring is damaged. 3. Diaphragm is broken (spring cover part of the water) 4. Export sensing hole blocked. 1. After the removal of foreign bodies break down, not when grinding or replacement. 2. Replacement O-ring decomposition. 3. Decomposition Replace the diaphragm. 4. Decomposition hole. Body parts of a liquid leak 1. Valve on the exhaust valve is loose or damaged, plug gasket damage. 1. Tighten loose parts, replacement of defective parts. Vibration or noise 1. Using the diaphragm pressure chamber occurs when the liquid gas. 1. The use of air plug, remove the diaphragm chamber of the air. (1) Pressure Range: It refers to the adjustable valve output pressure P2 range, in the range required to achieve the required accuracy. The major areas of the regulator and the regulator spring stiffness. (2) Pressure characteristics: it refers to the flow of g is constant, the pressure fluctuations caused by the input output characteristics of pressure fluctuations. The smaller the output pressure fluctuations, pressure reducing valve features as possible. Output pressure must be lower than the input pressure - constant pressure was essentially no change with the input. (3) Flow characteristics: it means that the input pressure - time, the output pressure with output flow and change of g hold of. When the flow of g changes, the output pressure changes as small as possible. Generally the lower the output pressure, which changes with fluctuations in the output flow of the smaller.
