hydraulic tube fittings,hydraulic hose,hydraulic fittings 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, while the locking balls from "tapered cylindrical ---" sleeves.

Two kinds of high-pressure hose fitting assemblies comparative analysis of nonlinear finite element
High fluorine plastic hose is usually made of Teflon inner tube, stainless steel wire reinforcing layer and the metal connector which is widely used in hydraulic equipment, air conditioning systems [1], passing control of rudder control aircraft hydraulic pressure and energy , is a modern aircraft, "ligament." In the pulsating experiments or actual use, due to design or manufacturing reasons, coupled by high / low temperature, the working medium pressure pulsation and other effects, there is a steel wire reinforced hose layer of broken wire, the inner tube burst hose connector near fracture and other issues (Figure 1), causing serious hazard to flight safety, because the hose rupture resulting in the loss of Hydraulic tube fittings system pressure causing frequent instances of flight accidents [2]. Figure 1 near the connector hose assembly hose assembly damaging effects of the quality factors of the thickness of the Teflon tube, the wire winding angle increase, the hose between the wires of the layer and enhancement of clearance or interference, the hose the amount withheld during assembly and joints of the structure and so on.
