Abstract

The invention discloses an electric and manual dual-purpose four-way valve. The electric and manual dual-purpose four-way valve comprises a motor and a reversing system, and further comprises a motorcontrol structure for controlling stop positions in the motor moving process, wherein the motor control structure is provided with a rotating shaft for driving the reversing system to rotate; the rotating shaft is provided with two collision blocks with set phase difference; the rotating shaft is driven by the motor to synchronously move with the motor; travel switches are respectively arranged inthe positions corresponding to all the collision blocks beside the rotating shaft; the collision blocks are cam-shaped; and when the collision blocks rotate, through the effect of outer convex partsof cams and the corresponding travel switches, two stop positions of the motor are respectively corresponding to two channel communicating states in the reversing system. The electric and manual dual-purpose four-way valve connects the motor control structure, the reversing system and the motor to transfer power through the rotating shaft and to realize synchronous rotation; the motor control structure is provided with two pairs of collision blocks and travel switches matched for use; and two acting positions are respectively corresponding to two communicating states of channels in the reversing system.

Description

Technical field[0001]The invention relates to a rotary drive four-way valve, in particular to an electric manual dual-purpose four-way valve for reversing control by rotary drive.Background technique[0002]The rotary drive four-way valve includes a rotary drive mechanism. The rotary drive mechanism includes electric and manual drive modes. Electricity usually realizes the switching of the internal connection mode of the four-way valve by controlling the rotation angle of the motor. The rotation angle of the motor is controlled by the control system The control command is issued and executed by the drive system. However, due to various reasons, including program errors in the control system, drive system movement errors and other factors, the actual execution of the drive system is not in place, which will cause the four-way valve to communicate. The switch is not in place, and the internal channel communication mode of the four-way valve is wrong or the communication performance is n...
