Problems solved by technology

[0002] In modern industrial automation equipment, cylinders are widely used, and the control of cylinders is usually controlled by electromagnetic reversing valve drive. This kind of control requires electrical participation, and it needs to use pressure signal detection or travel in the process of use. Switches or proximity switches or magnetic switch position detection and other signal transmitter equipment, with the cooperation of computer PLC program or single-chip microcomputer program, realize automatic control, and the control method is complicated

Abstract

The invention provides an automatic reversing valve, and relates to the field of valve bodies. The automatic reversing valve comprises a main valve and a pilot valve, wherein the main valve is a three-position five-way double-control valve, a first inflow port, a first outflow port, a second outflow port, a first control port and a second control port are arranged on the main valve, the first inflow port is used for communicating with a fluid source, the first outflow port is used for being connected with an air inlet in a cylinder, and the second outflow port is used for being connected withanother air inlet in the cylinder; the pilot valve is a two-position five-way one-control valve, a second inflow port, a third outflow port, a fourth outflow port and a third control port are arrangedon the pilot valve, the second inflow port communicates with the first inflow port, the third outflow port communicates with the first control port, the fourth outflow port communicates with the second control port, and the third control port communicates with the first outflow port. The automatic reversing valve can simplify the control mode for the cylinder.

Description

technical field [0001] The invention relates to the field of valve bodies, in particular to an automatic reversing valve. Background technique [0002] In modern industrial automation equipment, cylinders are widely used, and the control of cylinders is usually controlled by electromagnetic reversing valve drive. This kind of control requires electrical participation, and it needs to use pressure signal detection or travel in the process of use. Transmitter devices such as switches or proximity switches or magnetic switch position detection, with the cooperation of computer PLC programs or single-chip microcomputer programs, realize automatic control, and the control method is complicated. Contents of the invention [0003] The object of the present invention is to provide an automatic reversing valve, which is used for automatic and continuous reversing control of cylinders (except single-acting spring return cylinders) without the participation of electric control.
