Brief introduction of hydraulic quick connector
The hydraulic quick coupler is designed for special heavy load. The female joint is made of chrome-plated steel, and the male joint and female joint lock sleeve are hardened, which has good compression and fatigue resistance and adopts two-stage sealing. No leakage, with safe self-locking function.
This kind of joint is a kind of joint that can quickly disassemble and assemble pipes without tools. It has two structures: closed at both ends and open at both ends.
Principle of hydraulic quick joint
A quick joint for opening and closing both ends of a hydraulic quick joint consists of a joint body, a check valve core, a jacket, a steel ball, a spring and a sealing element. There is a one-way valve in the inner cavity of the connector. When the two connectors are separated, the valve core of the one-way valve extends outward under the action of their respective springs and abuts against the tapered holes of the connectors, so that the channels are closed, and the oil in the pipelines on both sides is sealed in the pipelines and cannot flow out; When the two connectors are connected, the two ejector pins at the front end of the check valve core collide, forcing the valve core to leave the tapered hole of the connector body, so that the oil in the pipelines on both sides is communicated. The body is locked by steel balls. When working, the outer sleeve presses the steel ball into the U-shaped groove of the joint body under the action of the spring to connect the joint body. The only difference between a quick connector with two open ends and a quick connector with two open ends is that there is no one-way valve in the connector cavity, and when the two connectors are separated, the channel cannot be closed. One end of the joint is connected with the hose through a three-petal hose joint, and the joint core of the hose joint is directly inserted into the quick joint.
Hydraulic quick coupler can be divided into:
Air quick connector, oxygen gas quick connector, gas-liquid quick connector, oil pressure quick connector, inert gas quick connector, cooling water temperature oil quick connector, semiconductor quick connector.
There are many kinds of hydraulic quick connectors, and different connectors have different characteristics, different assemblies and different installation methods, which also provide convenience for different modes of transportation. But it is particularly important that different joints have different precautions, so pay attention to safety while using hydraulic quick joints to avoid unnecessary accidents. With the continuous maturity of technology, I believe there will be more advanced technology to replace the current technology and provide greater convenience for human life.
