蒸汽减压阀出口压力频繁超范围波动，甚至，稳压调节功能丧失，一直是供热工程中极为普遍的问题。经过长期观察发现，其中很主要的一个原因，并非是阀门本身，而是系统中冷凝水侵入所致。通过对减压结构及其相关作用的研究，由于阀门自身结构的特点，阀内冷凝水积滞是必然的。对减压阀工作原理的每个细节的分析发现冷凝水对阀门的稳压调节功能具有破坏性。系统冷凝水的分离和排除，即{zd0}程度上保证正常干度的蒸汽的供给，是减压装置、稳定工作的关键。由此提出了减压装置设计的基本要求及相关措施。同时，更要认识到，减压装置z工作的直接对象大都是受压容器。“超压”对设备的工艺温度、产品质量及设备的自身安全构成直接威胁，须引起高度重视。 当我们经常能从运行人员那里听到这样一种反映：现在国产的减压阀，质量不行，后级压力经常稳不住，寿命太短，使用不久，就不起作用了。由于减压阀的失控，导致安全阀泄压，刺耳的啸叫，惊邻四座，不仅仅是浪费能源，而且直接影响了设备的安全运行。问题是，有些单位更换了进口阀，使用不久，上述问题照样出现。 通过对大量失控装置的调查（当然，不排除有阀门本身存在的问题）一个共同的发现：阀内普遍存有大量积水，其中不乏是才用不久的新阀，而且系统设计上均未采取冷凝水有效排除的措施。试验证明：将这些冷凝水排除之后，大部分阀门均可投入正常运行、从中得到启示：冷凝水是否就是造成减压装置失控的主要原因？通过思考，明确了研究方向，{dy}，要了解减压阀自身构造上是否有沉积冷凝水的可能？什么部位？第二，要解决冷凝水对稳压调节功能是否具有破坏性的作用？ 1 减压阀的结构与冷凝水积滞的可能性 应该讲，减压阀是一种较为复杂的阀门，结构繁杂，阀内套阀（一只阀中有二只功能截然不同的导阀和主阀）必须详细地来了解一下他们的结构和相关作用。以目前最常用的国产Y43H系列活塞式减压阀和进口的导阀型减压阀为例，进行对比介绍。（见图1及2）。 1.1 主要结构及相关区别 从图中可以看出，无论国产还是进口，结构虽然有所不同，但都是由调节弹簧组件、导阀组件、主阀组件及调节通道四大部分组成的。 1.1.1 调节弹簧组件和导阀组件：除了导阀的阀芯形状的区别外（一个是锥台，一个是球体）相差无几。 1.1.2 主阀组件：结构上xx相反 国产主阀的阀芯布置在阀座的下面，进气方向为低进高出，呈横S形； 进口主阀的阀芯布置在阀座的上面，进气方向为高进低出，呈反横S形。 1.1.3 压力调节通道（图1中的α、β、γ，图2中的a、b、c）布置形式不同 国产阀压力调节通道都预置在阀体内部（内置式），进口阀压力调节通道都是用铜管连接在阀体外面（外置式）。 1.1.4 β通道和b通道的功能区别 国产β通道是从导阀的环形汽腔直接通向下面的活塞气缸上腔，只有连接的功能。 进口b通道是从主供汽通道分流连接到下游出口的阀体上（一个很细的孔），这个通道作用很特殊，它不仅仅与主隔膜下腔形成压差，有助于主阀膜片的运动，同时也能排走一部分余压蒸汽及冷凝水到下游出口管段，更有利于主阀的迅速关闭。

Steam valve outlet pressure range of fluctuations in ultra-frequent, perhaps even a loss of regulatory function regulator, has been heating works very common problem. Observed over a long period, which is the main reason is not the valve itself, but the system due to condensation of water intrusion. Decompression through the right structure and its related effects, because of its structure the characteristics of the valve, the valve inside the condensate Jizhi was inevitable. Right valve works every detail of the analysis found that condensation of water on the valve of the regulator regulatory function have been devastating. System, condensate separation and exclusion, that is the maximum extent possible to ensure a normal supply of dry steam degrees is a decompression device, the key to stability. Thus put forward the basic requirements for decompression device design and related measures. At the same time, but also to realize that the work of decompression device z are the direct targets of large pressure vessel. "Ultra-pressure" on the equipment, process temperature, product quality and equipment pose a direct threat to its own security must pay close attention. As we often hear from the operating personnel there, a reflection: It is now made in China valve, quality not work, post-class steady pressure often do not live, life is too short to use soon, it will not work. As the valve out of control, resulting in pressure relief valve, ear-piercing whistle, panic o 4, not just a waste of energy, but also directly affect the safe operation of the equipment. The problem is that some units of the imported valve replacement, using the near future, these problems still occur. Through the investigation of a large number of control devices (of course, do not rule out a problem in the valve itself) a common finding: there are a large number of water valves, generally, many of them are only used near the new valve, and the system design were not condensate to take effective measures to exclude. Test Certificate: After exclusion of these condensed water, most of the valve can be put into normal operation, from which inspiration: whether the water is condensed out of control of the main reasons causing decompression device? Through thinking, a clear research direction, first, to understand the valve structure itself whether there is the possibility of deposition of condensed water? What parts? Second, to resolve the regulatory function of condensation water on the regulator whether the destructive effect? A valve structure and the possibility of condensate Jizhi Should say, pressure reducing valve is a more complex valves, structural complexity, valve sleeve valve (a valve there are two distinct features guided valve and main valve) must be in detail to understand what their structures and relevant role. Present the most commonly used home-made Y43H series piston valve and imports, reducing valve guide valve type, for example, to compare introduction. (See Figure 1 and 2). Major structural differences between 1.1 and related As can be seen from the diagram, either domestic or imported, structure, though somewhat different, but they are by the spring adjustment component, guided valve components, valve components and adjust the main channel of the four major components. 1.1.1 regulator valve spring components and guided components: In addition to the spool valve guide outer shape of the difference (one cone units, one sphere) or less the same. 1.1.2 main valve components: the structure of the opposite Made the main valve spool arranged on the valve seat below the inlet direction of low, sell high, showing horizontal S-shaped; Imports of the main valve spool arranged in the seat of the above, the direction of a high intake at low prices, showing anti-horizontal S-shaped. 1.1.3 Pressure regulator channel (Figure 1 in the α, β, γ, in Figure 2 a, b, c) arrangement of the different Chinese-made valve pressure regulator valve channels are preset in the internal (built-in), the import channel pressure regulator valve is connected to the body with the brass outside (external type). 1.1.4 β channel and b distinction between channel function Β channel is made from a circular steam valve guide cavity leads directly to the following on the piston cylinder chamber, only the connection functionality. Import b channel is diverted from the Zhugong gas channel connected to the valve on the downstream export (a very small hole), the role of this channel is very special, it not only with the main divide to form cavity pressure, helping the main valve membrane film movement, but also be able to drain away the part of the residual pressure steam and condensate water to the downstream export of tube sections, more conducive to the rapid closure of the main valve.
