Three-piece high platform locking handle weldingBall valvesIt is a special valve with a high platform, three-piece structure, locking handle and welded connection. Here are some details about this valve:
1. Working principle:Three-piece high-platform locking handle welded ball valves use ball rotation to control the flow direction and flow of fluids. When the sphere rotates, the sealing surface of the valve seat fits closely with the sphere to achieve a sealing effect. The design of the latch handle makes the valve more stable when opened or closed and reduces the possibility of misoperation. The welded connection gives the valve better strength and sealing performance.
2. Features:This valve features a high platform, three-piece structure, locking handle and welded connection. The high platform design makes the installation and maintenance of the valve more convenient, while also improving the overall stability of the valve. The three-piece structure makes the valve compact, small and lightweight. The design of the latch handle makes the valve switch more stable and reduces the possibility of misoperation. The welded connection method gives the valve better strength and sealing performance, and can adapt to various harsh working environments.
3. Application:Three-piece high platform locking handle welded ball valves are widely used in various industrial fields, such as petroleum, chemical, pharmaceutical, etc. In piping systems, this valve can be used to control the flow direction and flow of fluids to achieve automated control. At the same time, due to its good sealing performance and stability, this valve is also often used in occasions that require high sealing requirements and high stability.
4. Installation and maintenance:When installing and maintaining the three-piece high platform lock handle welded ball valve, special attention needs to be paid to the installation position and direction of the valve to ensure that the valve can work normally. At the same time, it is necessary to regularly check the sealing performance of the valve and whether the fasteners are loose, and carry out maintenance and maintenance in a timely manner.
Three-piece high platform locking handle welding ball valve is a special valve with high platform, three-piece structure, locking handle and welding connection, with good sealing performance and stability, which can meet the needs of various industrial fields. Understanding its working principle, characteristics, application, installation and maintenance information can help you better choose and use this valve.
