Description
Technical Field
The utility model relates to a quick-operation joint technical field especially relates to a twist formula quick-operation joint.
Background
The quick connector is a connector which can realize the connection or disconnection of pipelines without tools. Quick-operation joint can divide into: the quick connector for air, the quick connector for oxygen and fuel gas, the quick connector for gas and liquid sharing, the quick connector for oil pressure, the quick connector for inert gas, the quick connector for cooling water and temperature oil and the quick connector for semiconductors.
The quick coupling is divided into two-end opening and closing type, two-end opening type and one-way opening and closing type:
two-end opening and closing type
When not linked: when the ferrule of the parent body moves to the other end, the stainless steel ball automatically rolls outwards, the daughter body is disconnected under the action of the spring force of the common valve of the parent body and the daughter body, the valves of the daughter body and the parent body are respectively closed, and the fluid flow is instantly blocked.
When linking: when the daughter is inserted into the mother body, the ferrule returns to the original position under the action of the spring, the steel balls roll to lock the daughter in tight connection, meanwhile, the valves of the mother body and the daughter are mutually pushed to be opened, fluid flows, and the O-shaped ring can completely block the leakage of the fluid.
Both ends open type
Unlinked: when the ferrule of the mother body is pushed to the other end, the steel balls automatically roll outwards, so that the daughter is removed; since there is no valve between the daughter and the mother body, the fluid flows out.
When linking: when the sub-body is inserted into the main body, the ferrule is pushed to the previous position by the action of the spring of the ferrule, so that the steel balls are locked, the fluid flows, and the O-shaped ring is arranged in the ferrule to prevent liquid leakage.
One-way open and close
Unlinked: when the ferrule of the parent body moves to the other end, the stainless steel ball automatically rolls outwards, the child body is bounced open by the counterforce of the valve spring, and the valve can be automatically closed to block the fluid flow.
When linking: when the sub-body is inserted into the side of the parent body with the ferrule, the valve is opened to cause the fluid to flow, the gasket is pushed back to the original position by the force of the spring, the stainless steel ball is locked to ensure the sub-body/parent body connection, and the gasket inside can completely block the leakage of the fluid.
The existing twisting type quick connector is used for taking down a rotating ring of the integral connector in a long-time use process, so that the connector cannot be conveniently twisted and taken down.
To this end, we propose a twist-on quick coupling.
