DH7cs41 Hydraulic Control Check Butterfly Valve product details

DH7cs41 Hydraulic Control Check Butterfly Valve produced and sold by Baigang valve group is suitable for the medium of water pump outlet pipeline, as a closed circuit and check valve, used to avoid and reduce the pipeline system intermediate flow back and produce too large water hammer, to protect the pipeline system.The valve is opened by hydraulic drive and closed by heavy hammer potential energy.The valve can replace two valves of gate valve, butterfly valve and check valve after the installation of load pump.The flow resistance coefficient is only 30% of the above two valves.

Therefore, this kind of valve is energy saving product.When closing, the liquid 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 fast and slow concern change angles can be adjusted to prevent the occurrence of large water hammer.The valve also has the function of retaining pressure: the hydraulic system of the butterfly valve is equipped with an accumulator, storing pressure oil, replenishing the leakage of the system, and can automatically compensate the pressure.

At the same time, it has the function of automatic reset. When the valve opening is reduced (the heavy hammer falls) by 15°, the oil pump will start and automatically reset.Backup reset device, after the butterfly valve is opened, when a small amount of internal leakage accumulator is added in the hydraulic system, when the pressure drops to a certain value, the relay will make up for the pressure, the micro pressure relay to prevent the failure of the travel switch reset device, that is, the valve is opened in the position with double position protection function of maintaining pressure and maintaining position.
