             新设计、安装的控制系统，为了确保调节阀在开车时能正常工作，并使系统安全运行，新阀在安装之前，应首先检查阀上的铭牌标记是否与设计要求相符。同时还应对以下项目进行调试。 基本误差限；全行程偏差；回差；死区；柱塞阀泄漏量(在要求严格的场合时进行)。 如果是对原系统中调节阀进行了大修，除了对上述各项进行校验外，还应对旧阀的填料函和连接处等部位进行密封性检查。 调节阀在现场使用中，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、止回阀降温措施。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，排泥阀在管道高度大于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，氧气专用阀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 mm左右的胶皮安装电缆线。在使用维修中，旋塞阀在易爆场所严禁通电开盖维修和对隔爆面进行撬打。同时在拆装中不要磕伤或划伤隔爆面，检修后要还原成原来的隔爆要求状态。

 (7)执行机构的减速器拆修后应注意加油润滑，低速电机一般不要拆洗加油。装配后还应检查阀位与阀位开度指示是否相符。

           New design, installation of control systems, in order to ensure that the valves work properly in the car and make the system safe operation, before installing the new valve should first check whether the valve on the nameplate labeled consistent with the design requirements. The following items should also debug. Basic error limit; full stroke deviation; hysteresis; dead; leakage (in the strict occasions when). If the original system had valve repair,Oil pumps in addition to the above are verified, but also deal with old valve stuffing and sealing joints and other parts for inspection. Regulating valve in the field use, many are not because the valve mass is the cause, but to adjust the valve caused by improper use, such as the installation environment, location and direction improper installation or pipeline unclean, etc. reasons. Therefore, electric control valve in the installation should pay attention to the following: (1) regulating valves are field instruments, the Environment and temperature should be in the range of -25 ~ 60 ℃, relative humidity ≤ 95%. If it is installed in the open air or in high temperature, should take water, cooling measures. In a place away fromfire pumps the source of the vibration source or increase the anti-vibration measures. (2) regulating valve should normally be installed vertically, special circumstances can be tilted, such as the tilt angle is large or valve itself is too large weight bearing parts of the valve protection should be increased. (3) installation of the pipeline control valve generally not too high off the ground or floor, the pipe height is larger than 2m to set platform should be as much as possible, to facilitate the manipulator wheel and easy maintenance. (4) pipe valve should be cleaned before installation to remove dirt and weld slag. After installation, to ensureSplit case pumps not to impurities left in the valve body, the valve should be cleaned again, that pass into the media so that all valves should be open, to avoid impurities stuck. After using the hand wheel body, should be restored to its original neutral position. (5) In order to control valve in the event of failure or maintenance circumstances make the production process to continue, bypass pipe valve should be added. Should also pay particular attentionVacuum pumps to valve installation location is consistent with the requirements process. (6) electric control valve installed on the electrical part of the construction in accordance with the requirements relating to electrical equipment. The case of flameproof products should be "explosion hazardous area electrical installation standard" requirements for installation. Such as live wires and other six with SBH-type core or eight-core diameter was Φ11.3 mm or so of rubber installed cable. In-line pumps In the use and maintenance, in place non-explosive power open end surface for maintenance and pry on the explosion hit. Do not knock the same time dismantling the explosion injured or scratched surface, after overhaul to restore the original state of explosion-proof requirements. (7) The executive body of the reducer overhaul should be noted that after lubrication, low-speed motor fuel generally not washable. Assembly should also check the valve position after position with the valve opening direction is consistent.
