良工阀门球阀的安装事项

来源:http://www.jnlgvf.com/ 日期:2022-07-20 发布人:guanli
随着阀门技术的不断发展,阀门应用领域的不断拓宽,与之对应的阀门标准也越来越不可或缺。
With the continuous development of valve technology and the continuous expansion of valve application fields, the corresponding valve standards are becoming increasingly indispensable.
球阀是良工阀门产品中众多产品之一,那么球阀在安装的过程中需要注意以下
Ball valve is one of many products of Lianggong valve, so the following should be paid attention to during the installation of ball valve
问题,以避免造成不必要的损失。
Problems to avoid unnecessary losses.
1、安装前的准备
1. Preparation before installation
⑴球阀前后管线已准备好。前后管道应同轴,两法兰密封面应平行。管道应能承受球阀的重量,否则管道上需要配有适当的支撑。
⑴ the front and rear pipelines of the ball valve are ready. The front and rear pipes shall be coaxial, and the sealing surfaces of the two flanges shall be parallel. The pipeline should be able to bear the weight of the ball valve, otherwise the pipeline needs to be equipped with appropriate support.
⑵把阀前后管线吹扫干净,清除掉管道内的油污、焊渣和一切其它杂质。
(2) purge the pipelines before and after the valve, and remove the oil, welding slag and all other impurities in the pipeline.
⑶核对球阀的标志查明球阀完好无损。将阀全开全闭数次证实其工作正常。
(3) check the mark of the ball valve to make sure it is intact. Fully open and close the valve for several times to confirm its normal operation.
⑷拆去球阀两端连接法兰上的保护件。
(4) remove the protective parts on the connecting flanges at both ends of the ball valve.
⑸检查阀孔清除可能有的污物,然后清洗阀孔。阀座与球之间即使仅有微小颗粒的异物也可能会损伤阀座密封面。
(5) check the valve hole, remove the possible dirt, and then clean the valve hole. Even small particles of foreign matter between the valve seat and the ball may damage the sealing surface of the valve seat.
2、开始安装球阀
2. Start installing ball valve
⑴把阀装上管线。阀的任何一端都可装在上游端。用手柄驱动的阀可安装在管道上的任意位置。但带有齿轮箱或气动驱动器的球阀应直立安装,即安装在水平管道上,且驱动装置处于管道上方。
(1) install the valve on the pipeline. Any end of the valve can be installed at the upstream end. The valve driven by the handle can be installed at any position on the pipeline. However, ball valves with gear boxes or pneumatic actuators should be installed vertically, that is, installed on horizontal pipelines, and the driving device is above the pipeline.
⑵阀法兰与管线法兰间按管路设计要求装上密封垫。
(2) the sealing gasket shall be installed between the valve flange and the pipeline flange according to the pipeline design requirements.
⑶法兰上的螺栓需对称、逐次、均匀拧紧。
(3) the bolts on the flange shall be tightened symmetrically, step by step and evenly.
⑷连接气动管线(采用气动驱动器时)。
(4) connect pneumatic pipeline (when pneumatic driver is used).
3、良工球阀安装后的检查
3. Inspection of Lianggong ball valve after installation
⑴操作驱动器启、闭球阀数次,应灵活无滞涩,证实其工作正常。
(1) operate the driver to open and close the ball valve for several times, which should be flexible without stagnation, and confirm that it works normally.
⑵按管路设计要求对管道与良工球阀间的法兰结合面进行密封性能检查。
⑵ the sealing performance of the flange joint surface between the pipeline and Lianggong ball valve shall be checked according to the pipeline design requirements.
