The hydraulic valve block can be divided into strip blocks, small plates, cover plates and splints according to the structure.
The hydraulic valve block can be divided into valve installation bottom plate, pump valve block, logic valve block, superimposed valve block, special valve block, collecting tube and connecting block according to the application.
The hydraulic valve block in the actual hydraulic system is composed of the valve block body and various hydraulic valves, pipe joints, accessories and the like mounted thereon.
1, valve block
The 1 valve block is a key component of the integrated hydraulic system. It is the bearing body of other hydraulic components and the passage body of the oil passage.
2 valve block body is generally used in the rectangular outer body type, the material is generally aluminum or malleable cast iron.
3 valve block body is distributed with hydraulic valve related mounting holes, oil passage holes, connecting screw holes, positioning pin holes, and common oil holes, connecting holes, etc., in order to ensure the correct communication of the holes without interference, sometimes set the process hole. 4 The simpler valve block has at least 40-60 holes, and there are hundreds of slightly more complicated ones. These holes form a network of criss-crossing holes.
5 The hole on the valve block has various forms such as light hole, stepped hole and threaded hole. Generally, it is a straight hole, which is convenient for processing on ordinary drilling machine and CNC machine tool.
2, hydraulic valve
Hydraulic valves are generally standard parts, including various types of plate valves, cartridge valves, stacking valves, etc., which are mounted on the valve block by connecting screws to realize the control function of the hydraulic circuit.
3, joint pipe fittings
1 joint pipe fittings are used to connect the external piping to the valve block.
2 The hydraulic circuit composed of various valves and valve blocks must control the actuators such as hydraulic cylinders, as well as oil, oil return, oil drain, etc., which must be connected with external pipelines.
4. Other accessories
Including pipe connection flanges, process hole blockages, oil circuit seals and other accessories.
