Hydraulic hose quick connect

Hydraulic quick connectors are designed for special heavy loads. The material of the female connector is chrome-plated steel. The lock sleeves of the male connector and the female connector are hardened, with good pressure resistance and fatigue resistance. lock function.

The hydraulic quick connector head with opening and closing at both ends is composed of a connector body, a check valve core, a jacket, a steel ball, a spring and a seal. There is a one-way valve in the inner cavity of the joint body. When the two joint bodies are separated, the valve core of the one-way valve stretches out under the action of their respective springs and presses on the conical hole of the joint body to close the passage. , the oil in the pipes on both sides is enclosed in the pipes and cannot flow out; when the two joint bodies are connected, the two top rods at the front end of the one-way valve spool collide, forcing the spool to leave the conical hole of the joint body, so that the pipes on both sides of the pipe The oil is connected, and the two joint bodies are locked with steel balls. When working, the outer sleeve presses the steel balls in the U-shaped groove of the joint body under the action of the spring to connect the joint bodies. Common hydraulic line quick connects are: FK-A2 Series close type hydraulic quick coupling, FK-A3 Series close type hydraulic quick coupling.

Hydraulic quick couplings are often used in air piping, pneumatic tool accessories, ion cooling device piping, winemaking equipment, cutting oil piping for working machines, car washing machines, hydraulic equipment, construction machinery and other places. Common hydraulic quick connector models are: 3 8 hydraulic hose quick coupler, 1 2 hydraulic quick connect fittings, 1 4 hydraulic quick connect.
