Hydraulic valve is the most common system in industrial production. It is mainly used to control the flow direction of oil in the hydraulic system, and can also effectively regulate the pressure and flow. There are three types of hydraulic valves, namely pressure valve, directional valve and flow valve. For valves with the same shape, enterprises can choose different functions according to their different action mechanisms. Although there are many kinds of hydraulic valves, these hydraulic valves always have some common points
From the structure of hydraulic valve, each hydraulic valve includes valve body, valve core and components that drive the hydraulic valve core. The components here mainly refer to springs and electromagnets. In fact, the working principle of all hydraulic valves is the same. Their opening, the pressure difference between the inlet and outlet of the valve and the flow through the valve should conform to a certain proportion. Various hydraulic valves can also control their different parameters according to the actual needs
What requirements should hydraulic valves meet in actual work? Experts believe that the hydraulic valve must be sensitive, reliable in use, with small impact and vibration when working. In view of the small loss caused by pressure flowing through the oil, the sealing performance is good. Compact structure is the most basic requirement of hydraulic valve. It is also very convenient for maintenance, installation, adjustment and use, and has strong versatility
In order to ensure the normal operation of the hydraulic system, enterprises must clean the hydraulic system at ordinary times. Therefore, the hydraulic system must not be polluted before the new equipment runs. However, it is inevitable to cause internal pollution of the hydraulic valve in use. At this time, we need to pay attention to the internal cleaning of the components. If the new part contains burrs, debris and other contaminants, it means that the part is affected by poor storage and handling. At this time, it is necessary to thoroughly clean the oil tank, and take measures to remove pollutants if necessary to avoid safety failure caused by equipment operation
