Ball valves are a type of valve that came out of the 1950s and for half a century the ball valve has evolved into a major valve. Ball valve is mainly used to cut off or connect the media, but also for fluid regulation and control, V-type ball valve can be more precise flow control and regulation, and three-way ball valve is used to distribute media and change the media flow. First, the installation of the ball valve Before the installation 1, the valve before and after the pipeline is ready. Before and after the pipeline should be coaxial, two flange sealing surface should be parallel. Pipe should be able to withstand the weight of the ball valve, or the pipe must be equipped with appropriate support 2, the valve before and after the line purge clean the pipe to remove oil, welding slag and all other impurities 3, check the ball valve logo to identify the ball valve Undamaged Fully open the valve fully closed several times to confirm its normal work 4, Remove the protective valve on both ends of the flange connected to the ball valve 5, Check the valve hole to remove any dirt may be, and then clean the valve hole. Seat and ball even if only small particles of foreign matter may damage the valve seat sealing surface installation 1, the valve installed on the pipeline. Either end of the valve can be installed on the upstream side. The handle-actuated valve can be mounted anywhere on the pipe. But with a gear box or pneumatic actuator ball valve should be mounted upright, that is installed in the horizontal pipe, and the drive at the top of the pipe 2, valve flange and pipe flange according to pipeline design requirements fitted gasket 3, the flange On the bolts need to be symmetrical, one after another, even tighten 4, connect the pneumatic pipeline (pneumatic actuator) after installation inspection 1, the operation of the drive Kai, close the ball valve several times, should be flexible without astringent, confirmed its normal operation 2, according to the tube Road design requirements of the flange between the pipe and the ball valve sealing performance inspection Second, the maintenance of the ball valve â—† must first identify the ball valve, the downstream pipe has been removed after the pressure to disassemble and disassemble the operation â—† decomposition and reassembly Must be careful to prevent damage to the sealing surface of parts, especially non-metallic parts, remove the O-ring should use special tools â—† flange bolts on the assembly must be symmetrical, step by step, evenly tighten â—† cleaning agent and ball valve rubber, plastic Pieces, metal parts and working medium (such as gas) are compatible. Working medium for gas, gasoline (GB484-89) can be used to clean metal parts. Non-metallic parts with pure water or alcohol â—† decomposition of the individual parts can be cleaned by dipping. Non-metallic parts that remain undistracted may be cleaned with a clean, fine, silk-dipped cleaning cloth (to prevent the fibers from sticking to the parts). When cleaning, it must remove all the grease, dirt, glue, dust and so on adhering to the wall â—† Non-metallic parts should be removed from the cleaning agent immediately after washing and must not be soaked for a long time â—† After cleaning, (Can be used without cleaning cloth silk cloth) assembly, but not for a long time shelved, otherwise it will rust, dust pollution â—† new parts also need to be cleaned before assembly â—† Lubricated with grease. Grease should be ball valve metal materials, rubber parts, plastic parts and working medium are compatible. When the working medium is gas, for example, special 221 grease. Apply a thin layer of grease on the surface of the seal mounting groove, apply a thin layer of grease on the rubber seal, and apply a thin layer of grease on the sealing surface and the friction surface of the valve stem. â—† No metal Debris, fibers, grease (except for the provisions of the use of) dust and other impurities, foreign body pollution, adhesion or stay on the surface of the parts or into the cavity
We diviided the led light according to the using eviiroment. Most of our product is the commercial LED Lighting
Commercial lighting is a term used to describe lighting that is used in commercial spaces, including auto dealerships, distribution centers, churches, factories, offices, and warehouses. Unlike residential lighting, commercial lighting is made to withstand more abuse and has a longer lifespan.
While the focus of residential lighting is often on aesthetics, commercial lighting is task orientated. Commercial lighting systems are designed based on what the application is. For example, in an office-type setting, you may see task lighting, which illuminates specific areas where employees need concentrated light to be able to perform their jobs.
