In order to solve the technical problems, the invention adopts the technical scheme that: the four-way valve comprises a valve body and a valve core, wherein the valve core capable of rotating along the valve body is installed inside the valve body, a sealing piece used for sealing connection of the valve core is arranged between the valve core and the valve body, a channel A, a channel B, a channel C and a channel D are arranged on the valve core, the channel C and the channel D are of arc-shaped structures and are symmetrically arranged on two sides of the channel B, and the channel A and the channel B are perpendicularly arranged.
Furthermore, a force application rotating rod is arranged between the central position of the valve core and the valve body.
Furthermore, the valve body is provided with four pipe interfaces for connection, and the four pipe structures are arranged on the valve body in a pairwise symmetrical mode.
Furthermore, two pipe structures at one end of the valve body are connected with the fluid treatment equipment, and the pipe structure at the other end is respectively connected with a first liquid guide pipe and a second liquid guide pipe.
Compared with the prior art, the invention has the beneficial effects that:
1. the invention realizes the inlet and outlet switching of the fluid treatment equipment by controlling the opening angle of a four-way valve.
2. The four-way valve is used for replacing four valves to switch fluid, so that a large amount of time is saved when the four-way valve is used, and the switching efficiency is improved.

Detailed Description
It is easily understood that according to the technical solution of the present invention, a person skilled in the art can propose various alternative structures and implementation ways without changing the spirit of the present invention. Therefore, the following detailed description and the accompanying drawings are merely illustrative of the technical aspects of the present invention, and should not be construed as all of the present invention or as limitations or limitations on the technical aspects of the present invention.
One embodiment according to the present invention is shown in conjunction with fig. 1-8: can switch four way valve of fluid treatment facilities inlet and outlet pipeline, including valve body 1 and case 3, valve body 1 internally mounted has the case 3 that can follow its pivoted, be provided with between case 3 and the valve body 1 and be used for its sealing member 2 of sealing connection, be provided with passageway A5 on the case 3, passageway B4, passageway C7 and passageway D6, passageway C7 and passageway D6 set up to the arc structure, and the symmetry sets up in passageway B4 both sides, passageway A5 sets up with passageway B4 is perpendicular.
Install application of force bull stick 9 between 3 central point on the case and the valve body 1, drive case 3 through application of force bull stick 9 and rotate, realize the intercommunication of passageway and fluid erection equipment, valve body 1 is provided with four pipe connectors 8 that are used for the switch-on, four tubular structures are two bisymmetry settings on valve body 1, conveniently be connected with fluid erection equipment through four tubular structures, the symmetry sets up, control case 3 rotates the traffic, be convenient for put through, two tubular structures in 1 one end of valve body link to each other with fluid treatment equipment 10, another end tubular structure is connected with first catheter 11 and second catheter 12 respectively.
In the present embodiment, when the four-way valve body 1 is mounted on the fluid treatment apparatus 10, as shown in fig. 6, the valve is in a closed state, and the fluid in the inlet and outlet pipes of the fluid treatment apparatus 10 is disconnected from the pipes inside the fluid treatment apparatus 10 by the four-way valve.
