Hybrid control synchronous valve

Abstract

A hybrid control synchronous valve comprises a valve body of which the lower part is provided with an oil inlet cavity, and the oil inlet cavity is internally provided with a main valve core; an oil inlet is formed in the position, below the oil inlet cavity, of the valve body, and the both side faces of the upper part of the valve body are provided with a left oil outlet and a right oil outlet separately; the left oil outlet communicates with the oil inlet cavity through a left channel, and the right oil outlet communicates with the oil inlet cavity through a right channel; a left oil cavityis arranged at the position, above the left channel, of the valve body, and a right oil cavity is arranged at the position, above the right channel, of the valve body; the left oil cavity and the right oil cavity are provided with oil outlet valve cores; the right and left ends of the main valve core are provided with a right piston and a left piston, and the right side of the valve body is provided with a driving unit; the right end of the right piston is provided with a control part; the left end of the oil inlet cavity is provided with a through hole which is provided with an oil inlet sealing bolt, and a spring is arranged between the oil inlet sealing bolt and the left piston; and the upper ends of the left oil cavity and the right oil cavity are provided with through holes which areprovided with oil outlet sealing bolts, and springs are arranged between the oil outlet sealing bolts and the oil outlet valve cores. According to the hybrid control synchronous valve, the control accuracy is improved, and the cost is saved greatly; and the wording efficiency is improved.

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...
