For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Examples

Referring to fig. 1, the simple valve structure of the present embodiment includes a valve plate 3, a circular shaft 5, a welded pipe 4, a sleeve 7, and a bolt 6; the valve plate 3 and the circular shaft 5 are arranged in the flue 1, the shape of the valve plate 3 is matched with the shape of the flue 1, one side of the valve plate 3 is fixedly welded with the circular shaft 5, the welded pipe 4 is sleeved at two ends of the circular shaft 5, the welded pipe 4 is fixedly welded with the flue 1, and the valve plate 3 can be plugged in the flue 1 when being overturned along the circular shaft 5.

The mounting hole has been seted up in flue 1 bottom, sleeve 7 is fixed wears to establish in the mounting hole, sleeve 7 is concrete and the mounting hole welded fastening, wears to be equipped with bolt 6 in the sleeve 7, and bolt 6 closes through screw thread and sleeve 7 soon, through rotating bolt 6 for bolt 6 is located flue 1 one end extension or shortens, and when bolt 6 is located flue 1 one end extension, the shutoff is carried out in the upset of drive valve plate 3 to flue 1, and when bolt 6 is located flue 1 one end reduction, in flue 1 was opened to valve plate 3.

As shown in fig. 1, for convenient driving, the sleeve 7 is fixed obliquely to the flue 1.

In order to further reduce the cost of the simple valve, the sleeve 7 can be replaced by a nut, the round shaft 5 is replaced by round steel, and the cost is low.

Please refer to fig. 1, a baffle 2 is disposed in the flue 1 and located on the free side moving path of the valve plate 3, the flue 1 of the baffle 2 is fixed, and the baffle 2 is disposed at a proper position on the top of the flue 1 to prevent the valve plate 3 from rotating excessively during the opening process, so as to deform the top of the flue 1, wherein the side of the valve plate 3 fixed to the circular shaft 5 is a fixed side, and the side opposite to the fixed side is a free side.

When the valve is used, the bolt 6 is loosened when the valve is opened, namely, one end of the bolt 6 positioned in the flue 1 is shortened, and along with loosening of the bolt 6, the valve plate 3 also rotates anticlockwise around the circular shaft 5 under the driving of self gravity. When the end of the bolt 6 is loosened to the nut position, the valve plate 3 is also in the fully opened state. When the valve is to be closed, the bolt 6 is tightened, and as the bolt 6 is screwed, the valve plate 3 is also driven by the bolt 6 to rotate clockwise around the circular shaft 5. When the bolt 6 is fully screwed down, the valve plate 3 is also in a fully closed state; when the valve needs to be adjusted to different opening degrees, the bolts 6 are only required to be screwed or loosened to corresponding positions.

In the embodiment, round steel is used as a shaft, is connected with the valve plate 3 after being made into a simple hinge with the welded pipe 4 to form a simple rotary valve plate assembly, so that the valve plate 3 can smoothly rotate around the simple hinge; the simple valve does not comprise a valve shell, and the valve plate 3 and the simple hinge assembly are directly welded in the flue 1; in this embodiment, the valve itself does not have a housing with a shape, i.e. the shape of the flue 1, and the valve has a low cost and a simple structure.
