Application and Maintenance of Hydraulic Valve Group

1. Application

According to different situations and different uses of hydraulic valves, hydraulic valve can be divided into many types. This article focuses on one of them. This hydraulic valve group consists of four parts. It consists of inserts, control covers, pilots Two-way cartridge valve consisting of control valve and manifold block.

The main contents and functional purposes of these four parts are described below. The structure of the cartridge can be considered as a spool valve or a poppet valve. The function of this part of the components is very important, and it can well control the flow direction, flow speed and pressure of the oil in the channel or other places. The control cover can effectively control the real-time working conditions of the cartridge valve, mainly because there are many pilot control components in its composition. These components can adjust or control the working conditions of the cartridge valve. This control cover is basically a control cover. The bridge, which connects the control valve and the components, and the pilot control valve is also selected to be installed on it. The two-way cartridge valve is relatively common in the current situation in my country. From an economic point of view, because its components and necessary pipeline connections are relatively few, it is easy to integrate, so it is very convenient and suitable for large-scale mass production. , which can greatly reduce the production cost. From the point of view of use, its structure determines that its volume will be small so it is very convenient, and its control pressure switch speed is very high, so it is determined that it is very efficient and reliable when in use. In addition, it can also be controlled with large power, the advantage of doing so is that the loss of pressure will be reduced, and the loss of heat will also be reduced. Finally, two-way cartridge valves are not affected by commutation. The main function of the two-way cartridge valve is to connect the oil route or control it to disconnect.

2. Maintenance

With the growth of time, some failures of the hydraulic valve will inevitably occur, which involves the maintenance of the hydraulic valve. In actual production, the maintenance of the hydraulic valve is mainly to clean in time, select the combination of some parts, and repair the size. There is oil in the channel of the hydraulic valve, and the precipitation of oil pump can easily occur. These deposits will cause some unnecessary failures of the hydraulic valve, so we must clean it in time, disassemble and clean the hydraulic valve, so as to be timely. The function of the hydraulic valve is restored. Pay attention to safety when cleaning. Many sediments are not easy to clean and require some cleaning fluids. These cleaning fluids are generally corrosive or toxic, and some are even flammable, so you must be careful. After cleaning, the parts must be kept well to prevent them from being corroded again. After cleaning is complete and the installed hydraulic valve is tested, it can continue to operate. If some parts of the hydraulic valve are damaged and serious, in this case, recombination is generally selected. If the hydraulic valve is maintained by specialized experienced personnel, its life will be greatly increased, and its reliability and working performance will be maintained at the original level. Even so, we must be vigilant in daily production to prevent accident.
