The hydraulic system is inseparable from the existence of the hydraulic valve. The high-quality hydraulic valve can make the design of the hydraulic system more reasonable, the performance better, and the installation easier. Every enterprise should consider its rated pressure when choosing a hydraulic valve, as well as factors such as flow rate, installation form and economy.
Before choosing a hydraulic valve, the enterprise should determine the type of hydraulic valve according to the functional requirements of the system, and then select a reasonable hydraulic valve connection method according to the actual situation, which can also be a pipe connection or a plate connection. Next, we need to determine the rated pressure of the hydraulic valve according to the maximum working pressure designed by the hydraulic system, and then determine the flow specification of the hydraulic valve required by the enterprise according to the maximum flow of the hydraulic valve. For example, the relief valve should be selected according to the maximum flow rate of the hydraulic pump, and the flow valve should be selected according to the flow range controlled by the circuit. In the production process, the enterprise should try to choose the general product of the standard system.
Taking the directional valve as an example, you can choose the type of directional valve according to the working requirements of the system. For example, if the flow direction of the object is one direction, you need to choose a one-way valve, and if the actuator needs to complete the work cycle Or reciprocating motion, then you need to choose a reversing valve to determine the direction of the oil flow, and you can also turn on or off the oil circuit. If you want to complete two working states, you need to use a two-position reversing valve.
Next, let's look at the pressure valve. The pressure valve is an important device used to control the hydraulic system. You can choose the appropriate control valve according to the working pressure of the hydraulic system and the actual demand of the pressure. In the actual production process, in order to prevent the system from overloading, you can choose to connect a safety valve in parallel at the pump outlet, so that the safety of the entire system can be maintained. In short, when choosing a hydraulic valve, we must proceed from the perspective of safety to ensure production safety, which is the core of the choice.
