hydraulic fittings profiles and leak prevention

hydraulic fittings in the hydraulic system, the connecting member and the pressure tubing pressure tubing between. hydraulic fittings and the difference between the ordinary pipe joint largest and most significant difference is that the hydraulic pressure is larger staggering, hydraulic oil pipe suddenly burst impact force is great. hydraulic hose fittings can not be replaced by an ordinary dedicated connector, because the hydraulic are can withstand a lot of stress. Quick-change connectors, one is with a one-way valve, one is without a check valve. Application with check valve, check valve and the gas source is connected to the end, when you disconnect the check valve closes automatically when you turn on the activity side thimble-way valve is opened. Is the use of self-locking ball is embedded in the groove, hydraulic flange fittings the locking balls from "tapered cylindrical ---" sleeves. Pipe joints to prevent leakage in the hydraulic system, whether it is a metal fitting, or the hose connector is prone to leakage problems. For card sets of pipe joints, mostly due to the pipeline by a larger force or impact, so that the card sleeve loose or pipe end surface deformation caused by leaks, you should check whether the card sets out of round, edge or without defects, whether the pipe ends in good condition and the extent of compression ferrule nut, but also eliminate the pipeline force. For flared fittings, mostly due to excessive flaring, substandard quality requirements or repeatedly demolished, resulting in flaring deformation or cracks caused by leaks, then you can be re-flared front amputated.
