Products Design Features

Hydraulic Control Butterfly Valve is an advanced pipeline control equipment at home and abroad. It is mainly installed at the inlet of draulic turbine of Hydro power Station, or installed in water conservancy. Electric Power, water supply and drainage and other types of pump station pump outlet, to replace the check valve and gate valve functions. When working, the valve cooperates with the pipe host, according to the draulic transition principle, through the preset opening and closing procedure, effectively eliminates the water hammer in the pipe, realizes the reliable cut-off of the pipe, and plays the role of protecting the safety of the pipe system.

The company’s production of Hydraulic slow-closing Butterfly Valve Resistance Coefficient is small, high degree of intelligence, full-featured, stable and reliable performance, is my company designers in a wide range of collection. On the basis of summarizing the performance of similar products at home and abroad, the new intelligent energy-saving products are developed by introducing many research results from valve, draulic and electrical industries. The company has strong technical force, and according to the user’s special requirements for individual design, multi-dimensional to meet the needs of users of this type of products.

Description

The main features of the product are as follows:
1. can replace the pump outlet of the original Electric Gate Valve and check valve functions and mechanical, electrical, draulic system integration as a whole, reduce the footprint and infrastructure investment.

2. Elector-draulic control function is complete, without additional configuration can be used as an independent system on-site debugging. Control; can also be used as a unit of equipment in a distributed control system (DCS) , centrally managed by a central computer through a 1/0 channel, with pumps. Turbine, by-pass Valve and other pipeline equipment to achieve linkage operation, and with manual functions, no power supply can be realized when manually open. Close the valve to meet the special operating conditions of the valve commissioning, control requirements.

3. Good controllability, large adjustment range and strong adaptability. The elector-draulic control system has many regulating points, which can set up the opening and closing procedures according to different pipeline control requirements, the valve can be automatically opened and closed at a preset time, angle, and at a sub-fast or slow speed. It can realize non-electric valve closing, effectively eliminate the broken water hammer, prevent the accident of the pump and turbine, reduce the pressure fluctuation of the pipe network system, and ensure the safe and reliable operation of the equipment.

4. The main valve seal for three eccentric metal seal or double eccentric rubber seal structure, open and close easily. Reliable Seal; and an additional increase in the ECCENTRICITY, so that the valve has a good self-closing, self-sealing performance. Medium and Small Diameter Butterfly Plate is designed to streamline flat structure, large diameter butterfly plate design surface double flat truss structure, water flow smoothly, valve flow resistance coefficient is small, energy-saving effect is obvious.
