Embodiment

[0027] See attached Figure 1-6 As shown, a low-wear combined four-way valve of the present invention includes a valve body 1, and two valve cavities are arranged oppositely in the valve body 1, and each valve cavity is provided with an internal communication valve. A normal opening 21, a No. 1 opening and closing port 22, and a No. 2 opening and closing port 23. The valve body 1 is also provided with A port 111, B port 112, C port 113, D port 114, the A port 111 communicates with one of the normal openings 21, the C port 113 communicates with the other normal opening 21, and the B port 112 communicates with the No. 1 opening and closing port 22, The No. 2 opening and closing port 23 of the other valve chamber communicates, and the D port 114 communicates with the No. 2 opening and closing port 23 of one valve chamber and the No. 1 opening and closing port 22 of the other valve chamber. The valve body 1 is also provided with a link rocker mechanism driven by the electromagnet...

Abstract

The invention discloses a low-abrasion combined type four-way valve which comprises a valve body, wherein two valve cavities are oppositely formed in the valve body, each valve cavity is provided with a normal opening, a first opening and closing opening and a second opening and closing opening which are communicated in the valve cavity, and the valve body is further provided with a port A, a port B, a port C and a port D which are used for liquid feeding or liquid discharging. The port A is communicated with one normal opening, the port C is communicated with the other normal opening, the port B is communicated with the first opening and closing port of one valve cavity and the second opening and closing port of the other valve cavity, and the port D is communicated with the second opening and closing port of one valve cavity and the first opening and closing port of the other valve cavity; a connecting rod rocker arm mechanism driven by an electromagnetic driving part is further arranged in the valve body, and the connecting rod rocker arm mechanism can synchronously open and close the first opening and closing openings or the second opening and closing openings of the two valve cavities. According to the combined four-way valve, abrasion of valve components can be reduced, the stroke needed for opening or closing the valve is short, so that the needed driving force of an actuator is small.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a low-wear combined four-way valve. Background technique [0002] The four-way valve is a valve that controls the flow of fluid. It is equipped with two input ports and two output ports respectively. The main function is to cross and exchange the respective flow paths. The traditional four-way valve includes a spool structure and a rotating mechanism that drives the spool structure to rotate and slide, wherein the spool of the spool structure will inevitably produce sliding wear during the process of rotating and sliding to open and close the valve, and switching flow paths When the valve core needs to move more strokes; while the rotating mechanism needs to rotate and slide while keeping the valve tightly sealed, therefore, a large sliding driving force is required, and a certain amount of sliding wear will also occur. Most of the existing four-way valves use large stepping moto...
