Decomposition and maintenance of steam pressure reducing valve 1) decomposition method (1) Department of spring a) opened the valve cover, loosen the lock nut, rotate the adjusting screw counterclockwise, so that adjustment bolts to free state. b) Turn on the spring cover bolts, cover spring break, according to the order of the spring seat and spring break. (2) Department of diaphragm Unscrew the valve stem of the locking bolt, break spring seat, you can get rid of the diaphragm, and can be broken down on the valve stem guide seat. (3) Department of valve seat and valve Unscrew the mounting plate to the fixed seat bolts, you can break down the fixed plate, and can Xiexia stem, seat, the valve flap. At this time should be noted that the O-ring seal with the damage. 2) abnormal measures (1) caused by valve failure is mainly due to pipe sand, dust, etc., caused. Therefore, we must clear through the bypass and filter foreign matter. (2) gauge failure will occur, bypass valve leaks, filter clogging and so on. The following is a steam valve failure should be taken. Fault Fault measures the content Outlet pressure of less than the set pressure 1. The factory, there is no pressure regulator setting 2. Parts do not slide smooth. 1. On the sixth pressure regulation 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) 分解方法 (1) 弹簧部 a) 揭开阀罩，松开锁紧螺母，按逆时针方向旋转调节螺栓，使调节螺栓达到自由状态。 b) 打开弹簧盖的固定螺栓，分解弹簧盖后，按顺序分解弹簧座和弹簧。 (2) 隔膜部拧开阀杆上的锁紧螺栓，分解弹簧座，就可以除掉隔膜，并可以分解阀杆上的导向座。 (3) 阀座及阀瓣部拧开用来固定阀座的固定板上的螺栓，就可以分解固定板，并可以同时歇下阀杆、阀座、阀瓣。这时应注意密封用的O型圈的破损。 2) 异常措施 (1) 引起减压阀故障的主要原因是管道内砂子，灰尘等异物引起的。所以必须通过旁通及过滤网清楚异物。 (2) 也会发生压力表故障，旁通阀的泄漏，过滤器的堵塞等情况。蒸汽减压阀以下是发生故障时应采取的措施。故障内容故障原因措施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．安第六项调节压力 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。
