调节阀在使用中，很多往往不是因为调节阀本身质量所引起，而是对调节阀的安装使用不当所造成，如安装环境、安装位置及方向不当或者是管路不清洁等原因所致。因此电动调节阀在安装使用时要注意以下几方面：

　　(1)调节阀属于现场仪表，要求环境温度应在-25～60℃范围，相对湿度≤95%。如果是安装在露天或高温场合，应采取防水、降温措施。在有震源的地方要远离振源或增加防振措施。

　　(2)调节阀一般应垂直安装，特殊情况下可以倾斜，如倾斜角度很大或者阀本身自重太大时对阀应增加支承件保护。

　　(3)安装调节阀的管道一般不要离地面或地板太高，在管道高度大于2m时应尽量设置平台，以利于操作手轮和便于进行维修。

　　(4)调节阀安装前应对管路进行清洗，排除污物和焊渣。安装后，为保证不使杂质残留在阀体内，还应再次对阀门进行清洗，即通入介质时应使所有阀门开启，以免杂质卡住。在使用手轮机构后，应恢复到原来的空档位置。

　　(5)为了使调节阀在发生故障或维修的情况下使生产过程能继续进行，调节阀应加旁通管路。

　　同时还应特别注意，调节阀的安装位置是否符合工艺过程的要求。

　　(6)电动调节阀的电气部分安装应根据有关电气设备施工要求进行。如是隔爆型产品应按《爆炸危险场所电气设备安装规范》要求进行安装。如现场导线采用SBH型或其它六芯或八芯、外径为Φ11.3

　　a.两位阀：主要用于关闭或接通介质;

　　b.调节阀：主要用于调节系统。选阀时，需要确定调节阀的流量特性;

　　c.分流阀：用于分配或混合介质;

　　d.切断阀：通常指泄漏率小于十万分之一的阀。

　　对小口径的调节阀，尤其是超小流量调节阀，其节流间隙特小，介质中不能有一点点渣物。遇此情况堵塞，*好在阀前管道上安装一个过滤器，以保证介质顺利通过。带定位器使用的调节阀，定位器工作不正常，其气路节流口堵塞是*常见的故障。因此，带定位器工作时，必须处理好气源，通常采用的办法是在定位器前气源管线上安装空气过滤减压阀。

　　利用介质自身的冲刷能量，冲刷和带走易沉淀、易堵塞的东西，从而提高阀的防堵功能。常见的方法有：①改作流闭型使用;②采用流线型阀体;③将节流口置于冲刷*厉害处，采用此法要注意提高节流件材料的耐冲蚀能力。

　　Regulator in use, many more often than not because the regulator caused by itself, but the quality of the regulator caused by improper installation and use, such as the installation environment, installation position and direction is not clean pipe improper or by reason, etc. Therefore the installation use should pay attention to in the following aspects:

　　(1) belong to the field instruments, valves should be in environmental temperature - 25 ~ 60 ° c, more than 95% of relative humidity. If it is installed in the open or high temperature should be taken, waterproof, cooling measures. In place of source from source or increase vibration-proof steps.

　　(2) regulator shall generally be installed vertically, special circumstances can tilt Angle, such as big or valve itself when too much weight on the valve should be increased supporting a protection.

　　Install regulator (3) of the pipe from the ground floor or general not too high, more than 2m in pipe should be set when operating platform, and facilitate the maintenance.

　　Before installing valves (4) to clean out pipe, dirt and welding slag. After installation, to ensure that no residue in the body of the valve, also should be cleaned once again, namely the media should make all the valve opens, lest impurities stuck. After using the handwheel institutions in should be restored to the original sPACe location.

　　(5) in order to make the regulator in the fault or repair the production process can continue, by-pass pipe valves should be added.

　　Also, the regulator should pay special attention to the installation position meets the requirement of process.

　　(6) of the electrical parts of electric valves should be installed according to the relevant electrical equipment construction requirements. If flameproof products shall be according to the electrical equipment installation explosion hazard installation requirements specification. If SBH leads site type or other six or eight core, outer core for Φ 11.3

　　A. two valve: mainly used in closed or connect medium,

　　B. regulator: mainly used in regulating system. Choose valve, need to determine the flow characteristics; regulator

　　C. the purge valve: used for distribution or mixed media,

　　D. cut-off valve leakage rate: usually less than 10 PPM valve.

　　The regulator, especially for small exceed small flow regulator, the characteristics of small and medium throttling clearance can have a bit of slag. In this case, the best before the jam on piping installation of a strainer, to ensure smooth through the medium. The regulator used with locator, locator does not work properly, the gas path throttling blocked is one of the most common fault. Therefore, when working with locator, must deal with air, usually by the way is in the air pipe before locator installed on the air filter relief-pressure valve.

　　Using the medium itself, scouring and scouring energy to take things easy jam, prevent, so as to improve the valve. The common method is: (1) flow of adaptation and use, 2 the body, 3 will be placed the scour throttling mouth, use this law should pay attention to improving throttling materials of corrosion proof ability.
