Several common valves used in industrial pipelines, ball valves are the most widely used, whether it is ordinary medium pipelines for water, oil and gas or harsh working conditions containing high-hardness particles, whether it is low temperature, high temperature, or corrosive environment, you You can see the shadow of the ball valve. As a widely used general valve, it is necessary to understand the correct installation method in order to use the product correctly and scientifically (1) Preparation before installation
①Ball valve installation method The front and rear pipelines of the ball valve are ready. The front and rear pipes 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 the pipeline must be equipped with proper support.
②Purge the pipelines before and after the lubrication to remove oil stains, welding slag and all other impurities in the pipelines.
③Check the mark of the ball valve to find out that the ball is intact. Open and close the valve barrier several times to verify that it is working properly.
④Remove the protective part on the connecting flange of the left ball valve.
⑤Check the valve hole, remove possible dirt, and then clean the hole. Even small foreign matter between the valve seat and the ball may damage the sealing surface of the valve.
(2) Installation process
① Install the lubricating oil on the pipeline. Either end of the valve is installed on the free end of h. The valve for handle drive can be installed at any position on the pipeline. However, the manual ball valve with gear box and the pneumatic ball valve with pneumatic driver are installed upright, that is, installed on a horizontal pipeline, and the driving device is above the pipeline.
② Check the flange and pipeline flange connection pipeline design requirements to install gaskets.
③The bolts on the flange should be symmetrical and tightened one by one and evenly. ④When connecting pneumatic pipeline with pneumatic driver).
(3) Inspection after installation
① Operate the driver to open and close the ball valve several times. It should be flexible and free of stagnation to verify that it is working properly.
