    Hydraulic Quick Coupling Advantage

    Hydraulic quick coupling is designed for special heavy load. The main joint material is chrome plated steel. The lock sleeve of the male joint and the mother joint has been hardened. It has good pressure resistance and fatigue resistance. It adopts two-stage seal, no leakage, and has the function of safety self-locking.


    This kind of quick coupling is a kind of joint which not only does not need to use tools, but also can quickly assemble and disassemble pipelines. It has two kinds of structures, open and closed at both ends.


    The open-close quick coupler at both ends is composed of a joint body, a one-way valve core, a mask, a steel ball, a spring and a seal, etc. There is a one-way valve in the inner cavity of the joint body. When the two couplings' body are separated, the one-way valve core extends out under the action of their respective springs, and is pressed against the conical hole of the joint body to close the access, so that the oil in the tubes on both sides can not flow out. When two joint bodies are connected, the two top rods of the front end of the one-way valve core collide, forcing the valve core to leave the conical hole of the joint body, so that the oil in both sides of the pipe is connected. The two joint bodies are locked by steel balls. When working, the outer sleeve presses the steel balls in the U-shaped groove of the coupling's body under the action of spring, so that the joint body is connected.


    This kind of quick coupling is easy to disassemble, but its structure is complex and its local resistance loss is large. It is suitable for pipeline system with oil and gas as medium.


    The difference between two-end open-type quick connection and two-end open-close type is that there is no one-way valve in the inner cavity of the joint. When the two couplings' body are separated, the access can not be closed. One end of the joint is connected with the hose by a Three-lobe hose joint, and the joint core of the hose joint is directly inserted into the hydraulic quick coupling.
