Description

Technical Field

[0001] This invention relates to a quick-connection device, and more particularly to a novel modular valve hydraulic quick-connector. Background Technology

[0002] Quick couplings, including hydraulic quick couplings and various fluid quick couplings, are connection devices that quickly connect or disconnect pipelines, enabling rapid assembly and disassembly. Because quick couplings have a bidirectional backflow prevention function, preventing leakage when disconnecting pipelines, they are widely used in petroleum, metallurgy, hydropower, engineering machinery, shipbuilding, and electromechanical equipment industries. The connection structure of a quick coupling is its most important part; its connection method and structure directly determine the ease of use, reliability, and product quality. Quick couplings consist of two parts: a female connector and a male connector. A single quick coupling only enables the connection or disconnection of a single pipeline, which cannot meet the requirements of switching pipelines in multiple situations, especially in engineering equipment where a single pipeline cannot meet the usage requirements, thus limiting its use in some equipment.

[0027] In use, the combined flow channels achieve male plug combination and female socket combination, ensuring quantity matching and reducing the likelihood of errors. The male plug diameter is larger than the module valve male plug (b) diameter, and the female socket diameter is larger than the module valve female socket diameter, used to supplement the flow of the module valve male plug (b) and module valve female socket. In cases where the pressure relief pipeline has low flow and most joints cannot move after connection, this structure, through sliding sleeves a3 and b, provides a reserved movement position and has vent holes a and b, ensuring venting under various sealing conditions. Combined with the internal channels a and b of the module valve, the module valve female socket 56 can work independently, and the module valve male plug (b) 57 can also work independently. When switching working states, pushing causes the connector body sealing ring a to enter the return oil groove a62, and the connector body sealing ring b to enter the return oil groove b, achieving backflow. Both can be operated independently. Multiple holes are located on the front side of the installation port. When installed on equipment, inclined walls a and b are arranged parallel, with a large flow diameter. One function of the module valve is to provide fixation, using threaded fasteners. The system is fixed and has limiting steps a, b, and c to restrict its position. Internally, it is linked by a central vertical channel and two side horizontal channels a and b. The lower part has modular valve connectors a59 and b52. If the DC direction is used here, a modular valve connector structure can be used. However, the pressure relief pipeline is pressurized and has a small flow rate. By adding a pipeline next to it, the pipeline can only use the modular valve connectors a59 and b52 structure, which is shorter and easier to install inside. The male plug and female socket are not pressurized. The diameter of the male plug and female socket is larger than that of the modular valve female socket 56 and the modular valve male plug b57, which can increase the flow rate and meet more requirements. Modular valve connector springs a60 and b61 are set for easy reset. They can be connected to the corresponding male plug and female socket. They can be disconnected by pulling and the pipeline can be switched to form five pipelines. Two sets can merge and oil return can be achieved in the middle, ultimately forming a pipeline structure with switchable pipeline states.
