Rexroth hydraulic valve
A hydraulic valve is an automation component operated by pressure oil. It is controlled by a pressure distribution valve and pressure oil. It is usually used in combination with an electromagnetic pressure distribution valve. It can be used to remotely control the on and off of the oil, gas, and water pipeline systems of hydropower stations. Commonly used for clamping, control,lubrication and other oil circuits.There are direct-acting type and pilot type, and the pilot type is mostly used.
Hydraulic valve design principle
The design of the hydraulic valve is mainly for the design of the hydraulic valve group, and the oil circuit must be considered before the design of the hydraulic valve group. It is necessary to determine in advance which parts of the oil circuit can be integrated. The design of the oil circuit must be simple and save Go unnecessary steps. After determining the oil circuit, the main thing is the oblique hole and the process hole. These things in the oil path should be reduced. As long as it is enough, it is not necessary too much. Pay attention to the hole diameter in the design of the oblique hole and the process hole.
