Heavy hammer locking hydraulic control butterfly valve

Product Overview of Heavy Hammer Locking Hydraulic Control Butterfly Valve Heavy Hammer Locking Hydraulic Control Butterfly Valve has small flow resistance coefficient, high degree of automation, complete functions, stable and reliable performance. It is the product that our company’s designers have extensively collected, researched and summarized domestically. On the basis of the performance of similar foreign products, we introduced multiple research results from the valve, hydraulic, electrical and other industries, and developed a new generation of intelligent, high-efficiency and energy-saving products through thick and thin accumulation. The company has strong technical force and can independently design according to the special requirements of users to meet the needs of users for this type of products in all aspects. The hammer lock type hydraulically controlled butterfly valve mainly has the following characteristics. It can replace the functions of the original electric gate valve and check valve at the water pump outlet, and integrates the mechanical, electrical and hydraulic systems into a whole, reducing the floor space and infrastructure investment. , The electro-hydraulic control function is complete, and it can be used as an independent system for local debugging and control without additional configuration. It can also be used as an equipment unit of the distributed control system. The pass/channel is centrally managed by the central computer, and is connected with water pumps, and other The pipeline equipment realizes linkage operation and is equipped with manual functions. When there is no power supply, the valve can also be opened and closed manually to meet the valve debugging and control requirements under special working conditions. , good controllability, large adjustment range and strong adaptability. The electro-hydraulic control system is equipped with multiple adjustment points, and the opening and closing procedures can be set according to different pipeline control requirements to ensure that when the opening and closing conditions of the valve are met, the valve can automatically open and close at the preset time and angle. , slow off two stages. It can also realize non-electrical valve closing, effectively eliminate destructive water hammer, prevent water pumps and turbine units from running away, reduce pressure fluctuations in the pipe network system, and ensure safe and reliable operation of equipment. . The sealing surface of the main valve is a triple eccentric metal seal or double eccentric rubber seal structure. It is easy to open and close, has reliable sealing, and has an additional increased eccentricity, so that the valve has good self-closing and self-sealing performance. The medium and small diameter butterfly plates are designed into a streamlined flat plate structure, and the large diameter butterfly plates are designed into a double flat plate truss structure, with small crowding, smooth water flow, and the flow resistance coefficient of the valve is only much smaller than that of the check valve. The energy saving effect is obvious.
