introduction
In a hydraulic transmission system, power is transmitted and controlled by a pressurized fluid in a closed circuit: Quick-release connectors are used to connect hydraulic components without tools or special
Quick connection or disconnection of fluid conduits under special installation conditions:
GB/T 40565 specifies the dimensions and requirements of hydraulic quick-change connectors and consists of four parts:
--- Part 1: General purpose: The purpose is to determine the dimensions and requirements of hydraulic quick-change connectors for general purposes:
--- Part 2: 20MPa~31:5MPa flat type: The purpose is to determine the 20MPa~31:5MPa flat type hydraulic quick change joint
Head size and requirements:
--- Part 3: General type with threaded connection: The purpose is to determine the dimensions and requirements of general threaded connection type hydraulic quick-change connectors:
--- Part 4: 72MPa threaded connection type: The purpose is to determine the size of the threaded connection type hydraulic quick-change connector under 72MPa high pressure:
Inches and requirements:
The four parts of GB/T 40565 are formulated by ISO independent standards: In order to facilitate the systematic management and implementation of the standards, the independent standards are
The established standards are combined into partial standards:
Hydraulic transmission connection quick change connector
Part 1: General purpose
1 Scope
This document specifies the interface dimensions and requirements of hydraulic universal quick-change connectors and the A series universal quick-change connectors for agricultural machinery:
Additional requirements:
This document applies to hydraulic quick-change connectors of series A and B:
---A series is mainly used in Europe;
---B series is mainly used in North America:
