Hydraulic controlled eccentric semi-ball valve

' Hydraulically controlled eccentric semi-ball valve is currently the most advanced pipeline control equipment at home and abroad. It is mainly installed at the turbine inlet of hydropower stations. It is used as a turbine inlet valve or installed at the water pump outlet of various pump stations such as water conservancy, electric power, water supply and drainage, etc. To replace check valves and gate valves. When working, the valve cooperates with the pipeline host, according to the principle of hydraulic transition process, and through the effective setting of the electro-hydraulic control program, it can achieve reliable cutoff of the pipeline, effectively eliminate pipeline water hammer, and can realize automatic closing of the valve without electricity, which plays a Protect the safety of the pipeline system. The hydraulically controlled eccentric semi-ball valve produced by our company uses gas compression as the power source to automatically close the valve. It adopts an intelligent control system and can be equipped with manual or automatic locking devices according to user requirements. It has a small flow resistance coefficient, a high degree of automation, and complete functions. , stable and reliable performance. It is a new generation of intelligent technology developed by our company on the basis of extensive collection, research and summary of the performance of similar products at home and abroad, and the introduction of multiple research results from the valve, hydraulic, electrical and other industries. High-efficiency and energy-saving products. This series of valves have the advantages of stable performance, safety and reliability, complete functions, high degree of automation, simple structure, and small flow resistance coefficient. It has a complete hydraulic system and a reliable intelligent electrical control system, which can be operated locally or remotely. It can also be centrally managed through a central computer to achieve linkage operation control with water pumps and other pipeline equipment. When the oil pump unit loses power or malfunctions, the valve can still be opened or closed by shaking the manual pump. The hydraulic station and electrical control box of this series of valves are installed separately from the valve body, or they can be installed in conjunction. The valve body can be installed horizontally or vertically. It has the following characteristics. It can replace the water pump outlet stop valve and check valve, integrates machinery, electricity and hydraulics, and occupies a small area. During the opening or closing process of the valve, there is no friction between the valve seat and the ball crown, and the valve has a long service life. The opening and closing of the valve is not affected by silt and debris, and is suitable for muddy water conditions. It adopts two seals, metal and non-metal, with good self-sealing performance. The greater the water pressure, the greater the sealing specific pressure. It has a high degree of automation and can be controlled locally, remotely and linked. The electrical system can use an intelligent control system or an ordinary relay system. The hydraulic system motor has small power, high working efficiency, good pressure-holding performance, and long oil pump start-up interval. It has obvious opening indication and mechanical limit adjustment mechanism. The travel switch device is designed to be waterproof and dustproof, not exposed, has stable performance and long service life. The electrical operation interface is user-friendly and diverse. It can be designed with ordinary button type, text type, touch screen type, or the latest human-machine operation interface can be designed according to customer needs.
