球阀是昆山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 the many products of Kunshan Lianggong Valve. Therefore, during the installation process, attention should be paid to the following:

问题,以避免造成不必要的损失。

Problem 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,否则管道上必须配有适当的支撑。

The pipelines before and after the ball valve are ready. The front and rear pipelines should be coaxial, and the sealing surfaces of the two flanges should be parallel. The pipeline should be able to withstand the weight of the ball valve, otherwise appropriate support must be provided on the pipeline.

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。

⑵ Blow clean the pipelines before and after the valve, and remove oil stains, welding slag, and all other impurities from 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。

⑶ Check the markings of the ball valve to ensure that it is intact and undamaged. Fully open and close the valve several times to confirm its normal operation.

⑷ 拆去球阀两端连接法兰上的保护件。

Remove the protective components 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。

Check the valve hole to remove any 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。

⑴ Install the valve onto the pipeline. Either end of the valve can be installed on the upstream end. Valves driven by handles can be installed at any position on the pipeline. But ball valves with gearboxes or pneumatic actuators should be installed upright, that is, installed on horizontal pipelines, and the driving device should be 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。

Install a sealing gasket 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。

The bolts on the flange should be tightened symmetrically, step by step, and evenly.

⑷ 连接气动管线(采用气动驱动器时)。

Connect the pneumatic pipeline (when using a pneumatic driver).

3、良工球阀安装后的检查

3. Inspection of Kunshan 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 drive to open and close the ball valve several times, and ensure that it is flexible and free of stagnation, to confirm its normal operation.

⑵ 按管路设计要求对管道与昆山良工球阀间的法兰结合面进行密封性能检查。

⑵ Conduct sealing performance inspection on the flange joint surface between the pipeline and Kunshan Lianggong ball valve according to the pipeline design requirements.
