[0017] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clear, the utility model technical scheme will be described clearly and completely below in combination with the embodiment.

[0018] EMBODIMENT

[0019] As shown in Figure 1 , Figure 2 and Figure 3 , the switch electromagnetic valve includes valve body 10 and protection cover 20, and the connection of valve body 10 and electromagnetic controller is fixedly installed with assembly 11, the outer circle of assembly 11 is fixedly sleeved with slide 40, the side, away from valve body 10, of slide 40 is provided with taking and placing groove 41, protection cover 20 is movably sleeved on the outer circle of slide 40, and the inner wall of protection cover 20 is fixedly connected with slider 30 matched with the size of taking and placing groove 41, and slider 30 is located in the sliding groove of slide 40.

[0020] Specifically, taking and placing groove 41 is provided with two or more than two, and the number of slider 30 is same with the number of taking and placing groove 41, the electromagnetic controller of valve body 10 is covered by protection cover 20, so that the electromagnetic controller can be protected, and the electromagnetic controller of valve body 10 is prevented from being corroded by wind and rain, thereby the stability and service life of electromagnetic valve are improved.

[0021] Meanwhile, by rotating the protective cover 20, the slider 30 is controlled to be misaligned with the pick-and-place slot 41. At this time, the protective cover 20 cannot be separated from the slide 40, which increases the stability of the protective cover 20. When the slider 30 is aligned with the pick-and-place slot 41, the protective cover 20 can be lifted to easily separate it from the slide 40, which facilitates the maintenance of the valve body 10.

[0022] like Figure 2 As shown, the protective cover 20 includes an upper protective cover 21 and a lower protective cylinder 23. The inner ring of the upper protective cover 21 is fixedly fitted with a first adapter sleeve 22, and the inner ring of the lower protective cylinder 23 is fixedly fitted with a second adapter sleeve 24 that rotatably cooperates with the first adapter sleeve 22. The slider 30 is fixed on the inner wall of the lower protective cylinder 23.

[0023] It should be noted that the upper protective cover 21 and the lower protective cylinder 23 have the same diameter, and the slide 40 is in the shape of an "I", narrow at the top and wide at the bottom, which makes it convenient to place the lower protective cylinder 23 on the base of the slide 40.

[0024] like Figure 1 and Figure 2 As shown, a through hole is provided on one side of the lower protective cylinder 23, and a nut is fixedly installed in the through hole. The nut is threadedly connected to a fastening bolt, and one end of the fastening bolt abuts against the first adapter sleeve 22.

[0025] Specifically, through the cooperation of the fastening bolt and nut, when the fastening bolt is rotated, one end located inside the lower protective cylinder 23 will move away from or towards the first adapter sleeve 22. When the fastening bolt is away from the first adapter sleeve 22, the upper protective cover 21 and the lower protective cylinder 23 can rotate. When the fastening bolt is tightly fitted with the first adapter sleeve 22, the upper protective cover 21 and the lower protective cylinder 23 will not be able to rotate.

[0026] like Figure 1 , Figure 2 and Figure 3 Figure 3 As shown, the upper protective cover 21 has a through hole 211. A terminal block 12 is installed on the electromagnetic controller side of the valve body 10. The terminal block 12 passes through the through hole 211, and a sealing ring is fitted into the through hole 211.

[0027] Specifically, the protective cover 20 adopts a split design combining an upper protective cover 21 and a lower protective cylinder 23, which ensures that the upper protective cover 21 will not rotate along with the lower protective cylinder 23, thus preventing damage to the wiring terminal 12.

[0028] Working principle: the electromagnetic controller of the valve body 10 is covered by the protective cover 20, so that the electromagnetic controller of the valve body 10 can be protected from wind and rain corrosion, thereby improving the stability and service life of the electromagnetic valve. When the protective cover 20 needs to be disassembled, since the protective cover 20 is designed in a combined split type by adopting the upper protective cover 21 and the lower protective cylinder 23, when the fastening bolt is away from the first adapter sleeve 22, the upper protective cover 21 does not need to be rotated in the rotating process of the lower protective cylinder 23, after the slider 30 is aligned with the taking and placing groove 41, the protective cover 20 can be lifted to separate it from the sliding seat 40, the protective cover 20 can be hung on the cable of the electromagnetic controller, and the valve body 10 is convenient to maintain. When the protective cover 20 needs to be installed, the lower protective cylinder 23 is placed on the sliding seat 40 again, the lower protective cylinder 23 is rotated again to control the slider 30 to be dislocated with the taking and placing groove 41, at this time, the protective cover 20 cannot be separated from the sliding seat 40, finally, the fastening bolt is rotated to make it tightly fit with the first adapter sleeve 22, the upper protective cover 21 is limited by the terminal 12, so that the protective cover 20 as a whole cannot be rotated, and the quick disassembly and assembly of the protective cover 20 are realized.

[0029] The above examples are only used to illustrate the technical solutions of the present application, but not limit them.
