Hydraulic quick couplings are designed for special heavy loads. Mainly the joint material is chrome-plated steel. The male and female connectors are hardened. It has good pressure resistance and fatigue resistance. Adopt two-stage seal, no leakage, with safety self-locking function.
A joint is a type of joint that can be assembled and disassembled quickly without the use of tools. It has 2 structures, open at both ends and closed, open at both ends.
The quick connector with opening and closing at both ends is composed of a joint body, a one-way valve core, a sheath, a steel ball, a spring and a seal. There is a one-way valve in the inner cavity. joint agency. When the two joint bodies are separated, the one-way valve core stretches under the function of their respective springs, and presses against the conical hole of the joint body to close the passage, so that the oil in the pipes on both sides cannot flow out. When the two connecting bodies are connected, the two push rods at the front end of the one-way spool cannot flow out. The bump forces the spool out of the conical hole in the fitting body, which encourages oil communication on both sides of the pipe. The two joint bodies are locked by steel balls. When working, press the steel ball into the U-shaped groove of the joint body according to the spring function of the outer sheath to connect the joint body. This type of joint is easy to disassemble, but the structure is complicated. Its local resistance loss is very large. It is suitable for pipeline systems with oil and gas as the medium.
The difference between an open-ended quick connector and an open-closed connector at both ends is that there is no one-way valve in the inner cavity of the connector. When the two joint bodies are separated, there is no way to close the channel. One end of the connector is connected with the hose according to the three-blade hose connector, and the connector core of the hose connector is directly inserted into the quick connector.
