Background

The hydraulic valve is an automatic element operated by pressure oil, is controlled by the pressure oil of a distribution valve, is usually combined with an electromagnetic distribution valve for use, and can be used for remotely controlling the connection and disconnection of oil, gas and water pipeline systems of hydropower stations. It is commonly used for oil circuits of clamping, controlling, lubricating and the like. The direct-acting type and the pilot type are divided into a multi-purpose pilot type. The control method can be divided into manual, electric control and hydraulic control, the flow is regulated by utilizing the area of a throttling opening between a regulating valve core and a valve body and the local resistance generated by the throttling opening, so that the movement speed of an executing element is controlled, and the control method is classified according to the following steps: manual, automatically controlled, the liquid accuse, classify according to the function: flow valve (choke valve, speed governing valve, reposition of redundant personnel collecting valve), pressure valve (overflow valve, relief valve, sequence valve, unloading valve), direction valve (solenoid directional valve, hand-operated direction valve, check valve, liquid accuse check valve), divide according to the mounting means: the plate valve, tubular valve, superposition valve, screw inserted valve, cover plate valve and flow control valve are divided into 5 types according to their application. The method comprises the following steps: after the area of the throttling opening is set, the movement speed of the actuator with small load pressure change and low requirement on movement uniformity can be basically kept stable. A speed regulating valve: the pressure difference between the inlet and the outlet of the throttle valve can be kept to be a fixed value when the load pressure changes. Thus, after the throttle area is set, the governor valve can maintain a constant flow rate through the throttle valve regardless of changes in the load pressure, thereby stabilizing the speed of movement of the actuator. The flow dividing valve: no matter the load is large or small, two actuating elements of the same oil source can obtain the same flow which is the same shunt valve or the synchronous valve; the proportional diverter valve which distributes flow in proportion is obtained. Fourth, a current collecting valve: acting in opposition to the diverter valve, the flow into the combiner valve is apportioned. Fifthly, distributing and collecting valves: has two functions of a flow divider and a flow collector.
