counterbalance valve1. Keep the pressure stableIn a hydraulic system, a hydraulic balance valve can stabilize the hydraulic pressure.Generally speaking, in a hydraulic system, hydraulic actuators with different displacement will cause differences in pressure in the system.If it is not adjusted, some components will be damaged by excessive or small pressure.The hydraulic balance valve can adjust the pressure difference to keep the overall pressure in the hydraulic system stable and prevent the components from being subjected to inappropriate pressure.2.

Because it is difficult to understand the flow conditions of parts and pipelines in a hydraulic station from the outside, many friends who are new to the hydraulic industry have many difficulties in analysis and diagnosis. Therefore, today I will teach you how to find out the faults of the hydraulic station.
The pressure in the hydraulic system is abnormal and the pressure cannot go up or down. Pressure is one of the two most basic parameters of the hydraulic system, which to a large extent determines the performance of the hydraulic system. This fault manifests itself as follows: when adjusting the pressure of the hydraulic system, the adjustment failure occurs, the system pressure cannot be established, the pressure is insufficient, or there is no pressure, or it rises and then falls, the adjusted pressure is unstable, and the pressure fluctuates greatly.1.
Key points of knowledge about hydraulic valves(1) One-way valve1. Ordinary one-way valves only allow oil in one direction to pass through, and block the flow in the other direction. The control port of the one-way valve is connected to high-pressure oil, which can flow in the opposite direction. However, it should be noted that when the control oil port is not working, it must be connected to the oil tank, otherwise it will be difficult to reset.2. When the one-way valve is used to control the opening and closing of the oil circuit, the opening pressure is 0. 03- 0.
