The composition and function of hydraulic valves

The composition and function of hydraulic valves are well known. No hydraulic system, no matter how simple, can be without hydraulic valves; Hydraulic mechanical equipment with the same process purpose can form various hydraulic system schemes with completely different oil circuit structures through different combinations and uses of hydraulic valves. Therefore, hydraulic valves are the most diverse, widely used, and active components in hydraulic technology; The rationality of a hydraulic system design, the reliability of operation, and the convenience of installation and maintenance largely depend on the performance and parameter matching of various hydraulic valves used. Next, we will analyze why hydraulic valves are indispensable in hydraulic systems based on their composition and function.

Hydraulic valve is an automated component operated by pressure oil, which is controlled by the distribution pressure oil. It is usually used in combination with electromagnetic distribution valves and can be used for remote control of the on/off of oil, gas, and water pipeline systems in hydropower stations. Commonly used for clamping, control, lubrication and other oil circuits.

Hydraulic valve is a control component in hydraulic systems, used to control the flow direction, pressure, and flow rate of liquids in the system, so as to enable hydraulic actuators (hydraulic cylinders) and their driven working mechanisms to obtain the required direction of motion, speed (rotational speed), thrust (torque), etc.

In the hydraulic servo control system, the electro-hydraulic servo valve is the core component of the entire system, and the quality and performance of the electro-hydraulic servo valve determine the performance of the system.

Hydraulic valves are generally composed of a valve core, a valve body, and a device that controls and drives the movement of the valve core: the structure of the valve core is diverse; There are valve body (sleeve) holes or valve seat holes on the valve body that match the valve core, as well as main oil ports (inlet and outlet) for external oil pipes, control oil ports, and drain ports; Hand adjustable (dynamic), motorized, spring, electromagnet, hydraulic pressure, and electro-hydraulic combination are common control and driving devices for valve cores.
