This utility model relates to the technical field of hydraulic training equipment, specifically a teaching hydraulic
directional valve base plate, including a base plate body. The base plate body has
external connection holes A, B, T, and P located near the upper left, upper right, lower left, and lower right corners, respectively. The advantages are: it facilitates user connection of oil ports, making identification more intuitive, and provides clear anti-misconnection protection, preventing incorrect connection when using oil ports; it avoids the use of thread-locking
adhesive during sealing, reducing hydraulic oil circuit
contamination, and allows for quick and easy elastic locking of the outer end of the plug-in sealing plug, facilitating later disassembly, maintenance, and replacement; the nylon protruding set screws allow for easy fixing of the hydraulic
directional valve base plate to the teaching equipment mounting plate, preventing movement of the hydraulic
directional valve base plate during experiments; and the directional valve name
label facilitates user identification of the component.
