A Hybrid Control Synchronous Valve

Abstract

A mixing control synchronous valve, comprising a valve body, the lower part of the valve body is provided with an oil inlet chamber, the oil inlet chamber is provided with a main valve core, the valve body is provided with an oil inlet under the oil inlet chamber, and the valve body is on both sides of the upper part The left oil outlet and the right oil outlet are respectively, the left oil outlet communicates with the oil inlet chamber through the left channel, and the right oil outlet communicates with the oil inlet chamber through the right channel, the valve body is provided with a left oil chamber above the left channel, There is a right oil chamber above the right channel; the left oil chamber and the right oil chamber are equipped with oil outlet valve cores; the left and right ends of the main valve core are respectively equipped with a left piston and a right piston, and the right side of the valve body is equipped with a drive unit, and the right piston There is a control part at the right end of the oil inlet chamber; the left end of the oil inlet chamber is a through hole, and an oil inlet sealing bolt is arranged on the through hole, and a spring is arranged between the oil inlet sealing bolt and the left piston; the upper ends of the left oil chamber and the right oil chamber are through holes. The through hole is provided with an oil outlet sealing bolt, and a spring is arranged between the oil outlet sealing bolt and the oil outlet valve core. The invention improves the control precision, greatly saves the cost and improves the working efficiency.

Description

technical field [0001] The invention relates to the technical field of synchronous valves, in particular to a mixing control synchronous valve. Background technique [0002] The synchronous valve is used to ensure that two or more actuators (hydraulic cylinders or hydraulic motors) can still obtain the same or a certain proportion of flow when they are subjected to different loads, so that the same displacement or the same displacement between the actuators A hydraulic component that moves at high speed, the synchronous valve is used to synchronize the lifting mechanism. In the use of the synchronous lifting mechanism, a hydraulic valve is basically used to control an actuator. During the lifting process, due to the difference in working resistance, the lifting of the pillars is not synchronized, which causes the speed to be out of sync and affects the movement accuracy. The typical structure of the traditional synchronous valve is the hook type and the reversing piston typ...
