Since the dense high-pressure rubber hose fittings

Since the dense high-pressure rubber hose fittings (hereinafter referred to as self-dense type connector) was recently successfully developed a scientific research. Its basic principle is to use self-reinforced pipe pressure seals, rubber is completely solved by the ills caused by excessive compression. By high temperature, low temperature, flexural, pulse, pull-off force, blasting, pressure seal, aging, since the density and other Hydraulic adapters  tests prove that this hose connectors in addition to a superior sealing performance, but also has a light weight, small size, compact, reliable connection, diameter, flow resistance, long service life, material saving, easy processing, easy assembly, connectors can be used repeatedly recycled and other advantages. This article briefly describes the new hose connector design principles, structural characteristics and test results. First, the design of high-pressure piping, must meet a certain temperature range the connection strength and sealing performance of these two basic requirements. For high pressure rubber hoses, the connector must also consider the rubber aging effects caused by the compression and the elastic stress relaxation and so on. The current high-pressure rubber hose connector, although a lot of types, but the basic structural principles are followed low, medium pressure rubber hose coupling principle, which rely on the mandrel and the casing to get the clamping force between the seal and joint strength
