[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with its embodiments. It should be understood that the specific implementation methods described here are only used to explain the utility model and do not limit the protection scope of the utility model.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0028] like Figure 1-4 As shown, a valve in one embodiment of the utility model includes a valve body 1, a sleeve 2 and a rotating assembly 3; a first channel 5 is provided in the valve body 1, a first partition 4 is provided in the first channel 5, and a through hole 6 communicating with the first channel 5 is provided on the first partition 4; the sleeve 2 is inserted on the valve body 1 and communicated with the first channel 5; the rotating assembly 3 is inserted in the sleeve 2 and threadedly connected with the sleeve 2, the rotating assembly 3 abuts against the first partition 4, and the rotating assembly 3 is used to control the communication state of the through hole 6.

[0029] The above valve controls the contact state of the rotating component 3 and the first partition 4 by rotating the rotating component 3 according to the demand. When the rotating component 3 is in contact with the first partition 4, the through hole 6 is in a closed state, thereby closing the first channel 5; when the rotating component 3 is separated from the first partition 4, the through hole 6 is in a connected state, thereby opening the first channel 5. The valve solves the problem that the traditional steam trap cannot control its switch state according to actual needs.
