[0021] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0022] like Figure 1As shown, a multi-pressure controlled two-position five-way electromagnetic reversing valve comprises a first air inlet 2 arranged on the side of a valve body 1, working air ports 3 arranged on both sides of the first air inlet 2, and two exhaust ports 4 arranged on the other side of the valve body 1, and a second air inlet 5 is arranged on the side of the valve body 1 between the two exhaust ports 4. When the two-position five-way electromagnetic reversing valve is assembled and used, multiple two-position five-way electromagnetic reversing valves are mounted on the same assembly plate 10, and the valve body 1 is screwed on the assembly plate 10. The assembly plate 10 is connected to an external air source through a main pipe, and a plurality of branch pipes are arranged on the main pipe to communicate with the first air inlet and the working air port of each two-position five-way electromagnetic reversing valve. Under normal circumstances, multiple two-position five-way solenoid reversing valves are connected to the same pressure air source, and the second air inlet 5 is blocked. When some solenoid valves need to select different pressure air sources for input, just plug the first air inlet 2 with a rubber plug, connect the second air inlet 5 to another air source, and input the air source from the second air inlet 5. The switching is flexible and meets the customer's requirements for the use of different cylinder loads, thereby realizing multi-pressure control.

[0023] Meanwhile, the two-position five-way electromagnetic reversing valve can also be used alone, and it is only necessary to block the second air inlet 5 at the upper end of the two-position five-way electromagnetic reversing valve.

[0024] By setting two exhaust ports, exhaust is discharged during reversing operation; during normal use, the exhaust port does not discharge exhaust. When the solenoid valve fails, leakage will occur at the exhaust port, which is convenient for troubleshooting.

[0025] like Figure 1 As shown, the first air inlet 2 is a through hole, and the branch pipe has an open opening, so that a rubber plug can be easily inserted into the first air inlet 2 .

[0026] like Figure 3 As shown, a rubber plug 11 is provided in the first air inlet 2. When installing the rubber plug 11, the valve body is removed from the container plate, the rubber plug is plugged into the first air inlet 2, and then the valve body is installed on the container plate, thereby achieving the sealing of the first air inlet 2.

[0027] like Figure 2 As shown, the second air inlet 5 is a threaded hole, and a threaded plug 6 is provided in the threaded hole to block the second air inlet 5 through the threaded plug 6 .

[0028] The exhaust port 4 is provided with a muffler to reduce noise.

[0029] like Figure 1 As shown, an end cover 7 is provided at the right end of the valve body 1.

[0030] A return spring 8 is provided between the end cover 7 and the valve stem; a positioning head is provided inside the end cover 7, a positioning groove is provided at the right end of the valve stem, the right end of the return spring 8 cooperates with the positioning head, and the left end of the return spring 8 penetrates into the positioning groove, thereby realizing the positioning of the return spring 8.

[0031] The end cover 7 is provided with a reset air hole 9, which is communicated with the air inlet on the valve body. The reset spring 8 is pneumatically reset to ensure flexible and reliable switching.

[0032] In the description of the present invention, it should be noted that the terms "left", "right", "up", "down", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection, it can be a direct connection, it can be an indirect connection through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
