Multi-channel split-flow valve

Abstract

The invention discloses a multi-channel split-flow valve. The multi-channel split-flow valve comprises a valve body, a valve core, a motor, an oil pump, an oil way combination body and an oil cylinder; the valve body is a cylindrical shell, and a plurality of outer channels communicating with the interior of the valve body are formed in the side wall; the valve core is in a round rod shape and isarranged in the valve body; the outer wall of the valve core closely attach to the inner wall of the valve body; a plurality of inner channels are arranged on the valve core; an output shaft of the motor extends into the valve body to be connected with the oil pump through a coupler; the oil cylinder comprises a cylinder barrel and a piston rod; the tail end of the piston rod is connected with oneend of the valve core; the piston rod is sleeved with a fixing sleeve; and the fixing sleeve is connected with the coupler through a hinged connecting rod. The multi-channel split-flow valve has thebeneficial effects that the motor and the oil pump drive the single valve core to rotate and stretch out and draw back so as to control effective matching of the valve core and the valve body, and control over the valve core is more flexible; and the valve core is provided with the plurality of inner channels matched with the plurality of outer channels formed in the valve body, the failure rate is lowed and the size is reduced due to the single-valve-element multi-channel structure, and meanwhile, the settable number of the channels is increased due to the round-rod-shaped valve core.

Description

technical field [0001] The invention relates to the technical field of valve bodies, in particular to a multi-channel diverter valve. Background technique [0002] In order to realize the diversion control of various liquids or gases, it is usually necessary to use a diverter valve body with multiple channels. The existing multi-channel diverter valve is usually equipped with a plurality of individually controlled spools in a valve body. By controlling different valves The opening and closing of the spool realizes the flow control of each channel. Due to too many spools, this kind of diverter valve has a high failure rate and occupies a large volume; the number of spools that can be set on a single valve body is limited, and is affected by the structure of the spool. The position where the core is arranged on the valve body will also be limited, which will affect the arrangement of the external piping of the diverter valve. In addition, the existing diverter valve uses a hy...
