进口蒸汽止回阀
ORSEN系列-进口蒸汽止回阀(Steam Check Valve) 
概述：蒸汽止回阀又称蒸汽止逆阀、蒸汽单流阀、蒸汽单向阀或蒸汽逆止阀，其作用是保证蒸汽管路中的介质定向流动而不致倒流的功能。进口蒸汽止回阀(Steam Check Valve) 是指用在蒸汽管道上的止回阀，启闭件靠蒸汽（或者冷凝水）流动和力量自行开启或关闭，以防止蒸汽（或者冷凝水）倒流的阀门。一般采用旋启式或者升降式两种结构，蒸汽止回阀适用于公称压力PN1.6-4.0Mpa,工作温度-29～350℃的石油、水、蒸汽工业等各种工况的管路上。蒸汽止回阀按结构划分，可分为升降式止回阀、旋启式止回阀和蝶式止回阀三种。升降式止回阀可分为立式和直通式两种。旋启式止回阀分为单瓣式、双瓣式和多瓣式三种。
蒸汽止回阀的安装应事项：
1、在管线中不要使止回阀承受重量，大型的止回阀应***支撑，使之不受管道系统产生的压力的影响。
2、安装时注意介质流动的方向应与阀体所标箭头方向一致。
3、升降式垂直瓣止回阀应安装在垂直管道上。
4、升降式水平瓣止回阀应安装在水平管道上。
德国进口蒸汽止回阀特征：

Inlet steam valve
ORSEN series - inlet steam valve (Steam Check Valve)
Overview: steam valve, also known as steam check valve, single-flow steam valve, steam check valve or check valve steam, its role is to ensure the steam line of medium directional flow without backflow function. Inlet steam valve (Steam Check Valve) refers to the use of a check valve in the steam pipe, opening and closing pieces by steam (or condensate) flows and forces to turn on or off, to prevent the steam (or condensate) backflow valve. Generally use Swing or lift the two structures, the steam valve for nominal pressure PN1.6-4.0Mpa, oil, water, steam, industrial and other conditi*** of operating temperature -29 ~ 350 ℃ in the pipeline. Steam valve according to the structure can be divided into lift check valve, swing check valve and butterfly valve three. Vertical lift check valve can be divided into two kinds and straight. Swing check into a single lobe, double valve type and Orange Peel three.
Steam valve should be installed matters:
1. Do not check valve in the pipeline to withstand the weight, a large check valve should be self-supporting, so that the piping system from the impact of stress.
2, note the direction of flow of the medium should be c***istent with the direction of the arrow on the valve installation.
3, the vertical lift check valve should be installed in a vertical pipe.
4. The level of valve lift check valve should be installed in horizontal pipelines.
Germany imported steam valve features:
A steam valve opening and closing parts in production back rigorous experimental treatments only, can play a full role backstop.
3, a component of both the steam valve through a special polishing process, seals made of imported materials, reduce noise during backstop, truly green energy.
3, the sealing surface of the steam valve and check valve seat with different hardness carbide spray from. Reliable sealing, high hardness; wear resistance, high temperature, good anti-abrasion performance and long life.
4, reasonable structure, reliable sealing, excellent performance, attractive appearance;
5, sealing surface Co based alloy, wear, corrosion, anti-friction, long life;
6, part material, flange and butt number size according to the actual working conditi*** or user requirements reasonable matching, to meet the various needs of engineering.
Inlet steam valve basic parameters:
Nominal or pressure level: PN1.0-16.0MPa, ANSI CLASS 150-900, JIS10-20K
Nominal diameter or diameter: DN15 ~ 900, NPS 1/4 ~ 36
Connection: flange, welded, threaded, socket weld, etc.
Temperature: -196 ℃ ~ 540 ℃
Body material: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti
