| product description: This butterfly valve is suitable for the pump outlet pipeline where the medium is water. It is used as a closed circuit and check valve to avoid and reduce the backflow of the medium in the pipeline system and excessive water hammer to protect the pipeline system.The valve is opened by hydraulic drive and closed by the potential energy of the heavy hammer. The opening and closing is flexible and reliable.After the valve is installed with a load pump, it can replace the gate valve, butterfly valve and check valve.And the flow resistance coefficient is only 30% of the flow resistance coefficient of the above two valves.Therefore, this type of valve is an energy-saving product.When closing, the hydraulic control device is divided into two stages: fast closing and slow closing: the first 60° is fast closing, and the last 30° is slow closing. According to different working conditions, the fast and slow closing time and the switching angle of fast and slow closing can be adjusted to prevent Larger water hammer occurred.The valve also has the function of maintaining pressure: the hydraulic system of this butterfly valve is reset with an accumulator, which stores pressure oil to supplement the leakage of the system and can automatically compensate for the pressure.At the same time, it has an automatic reset function. When the valve opening is reduced by 15° (weight drop), the oil pump starts and automatically resets.Standby reset device. After the butterfly valve is opened, when there is a small amount of internal leakage accumulator supplemented in the hydraulic system, when the pressure drops to a certain value, the relay will send an order to make pressure to prevent the pressure relay from malfunctioning. It is equipped with a trip switch reset device. The opening position of this valve has dual-position protection of pressure and position protection |
