Detailed Description

The present utility model will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the present utility model, but are not intended to limit the utility model in any way. It should be noted that variations and modifications could be made by those skilled in the art without departing from the inventive concept. These are all within the scope of the present utility model.

In the technical solutions according to the present utility model, unless explicitly specified and limited otherwise, the terms "mounted", "connected", "fixed" and the like are to be understood in a broad sense, for example, they may be fixed connections, they may be removable connections, or they may be integral; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

In the description of the utility model, "a first feature" may include one or more such features, and "a plurality" may mean two or more, and that a first feature "above" or "below" a second feature may include both the first and second features being in direct contact, or may include both the first and second features not being in direct contact but being in contact with each other through additional features therebetween, with the first feature "above", "over" and "above" the second feature including both the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is higher in level than the second feature.

as shown in fig. 1, and referring to fig. 2 and 3 as necessary, in the present embodiment, the underlying valve body 1 includes: the housing 11 and the valve body 12 provided on the housing 11. The valve body 12 includes a valve plate 121, a rotating shaft 122 driving the valve plate to rotate, and a rotary reset member 123.

The driving member 124 is accommodated in the housing 11, the driving member 124 is connected with the rotating shaft 122 of the valve body 12, and when in operation, the driving member 124 drives the rotating shaft 122 to rotate in a first rotating direction (i.e. the rotating shaft 122 rotates in the axial direction, which may be clockwise or counterclockwise), the reset pretightening force generated by the rotary reset member 123 causes the valve plate 121 to rotate in a second rotating direction (i.e. the plane of the center point of the valve plate 121 turns over), and the plane of the first rotating direction and the plane of the second rotating direction are not the same plane. In addition, the lower valve body 1 further comprises a gear set, and the rotating shaft 122 drives the gear set to rotate.
