Electromagnetic valve driver which can be cascaded in series

Abstract

The invention relates to the technical field of electromagnetic valve drivers, in particular to an electromagnetic valve driver which can be cascaded in series. The electromagnetic valve driver whichcan be cascaded in series comprises a front cover, a mounting plate and an electromagnetic valve driving plate. An indicating lamp is arranged on one side of the top of the electromagnetic valve driving plate. A connector socket is connected with the electromagnetic valve driving plate and arranged on the mounting plate. A plurality of electromagnetic valve drivers which can be cascaded in seriescan be connected in series. According to the electromagnetic valve driver which can be cascaded in series, one support controller can communicate with a plurality of electromagnetic valve drivers, sothat the movement of a plurality of hydraulic supports can be controlled, mounting and wiring are simplified, the number of support controllers is reduced, and the cost is reduced. After the electromagnetic valve drivers which can be cascaded in series are connected in series, no address needs to be configured, and the support controller can communicate with each electromagnetic valve driver; andin the use process, the position and series number of the electromagnetic valve drivers can be flexibly adjusted according to needs, communication and control are not affected, and using convenience is realized.

Description

technical field [0001] The invention relates to the technical field of solenoid valve drivers, in particular to a solenoid valve driver that can be cascaded in series. Background technique [0002] The hydraulic support is used to support the coal mine face and needs to move with the mining progress. The support electro-hydraulic control system is used to control the cylinder of the hydraulic support to control the movement of the hydraulic support. When controlling the movement of the oil cylinder, the bracket control equipment needs to use electricity to control the solenoid valve (also called the electromagnetic pilot valve) to pull in or disconnect, resulting in changes in the hydraulic circuit, and using hydraulic action to drive the hydraulic valve of the control cylinder to open or close, thereby controlling the hydraulic pressure of the cylinder. sports. The voltage and current output by the bracket control equipment are often too small to drive the solenoid valve, ...
