Abstract
The utility model discloses an eccentric butterfly valve which comprises a valve rod arranged in a valve body, wherein at least one semicircular hole is arranged on the valve rod, and the valve rod penetrates through a butterfly plate; the butterfly plate is provided with a symmetrical semicircular hole at a position corresponding to the semicircular hole; the two semicircular holes form a circular hole; pins used for fixing the butterfly plate and the valve rod are inserted in the circular hole; a backstop gasket is arranged at each of an upper end face and a lower end face of the butterfly plate; and the backstop gaskets penetrate through the valve rod and are clamped in the valve body. When the eccentric butterfly valve is adopted, the sealing position of the butterfly plate can be fixed, and the problem of the leakage of the valve due to the displacement of the butterfly plate and a sealing surface when the valve rod receives an unexpected axial force is avoided.
Description
Technical field
The utility model relates to a kind of eccentric-butterfly-valve.
Background technique
Existing its sealing station of eccentric-butterfly-valve is not done other processing, and after butterfly plate and sealing surface displacement, valve can be revealed.
Summary of the invention
Because the problems referred to above that prior art exists the utility model proposes a kind of eccentric-butterfly-valve, it can effectively address the above problem.
To achieve these goals, the utility model has adopted following technological scheme:
The utility model proposes a kind of eccentric-butterfly-valve, comprise that one places the valve rod of valve body, which is provided with at least one semi-circular hole, and valve rod runs through a butterfly plate, butterfly plate is being provided with the semi-circular hole of a symmetry with the corresponding position of semi-circular hole, and this two semi-circular hole forms a circular port, inserts the pin of fixing this butterfly plate and valve rod in this circular port, the upper and lower end face of butterfly plate respectively is provided with a floor clip, and this floor clip passes valve rod and is stuck in the valve body.
As further feature of the present utility model, the cross section of floor clip is circular.
As further feature of the present utility model, the material of floor clip is 304 stainless steels.
Because adopt above technological scheme, eccentric-butterfly-valve of the present utility model is the sealing station of butterfly plate fixedly, thereby prevent that valve rod is subjected to the problem that unexpected axial force makes butterfly plate and sealing surface displacement cause valve to be revealed.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure: 1, valve rod; 2, butterfly plate; 3, pin; 4, floor clip.
Embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawings below:
As shown in Figure 1, a kind of eccentric-butterfly-valve, comprise that one places the valve rod 1 of valve body, which is provided with at least one semi-circular hole, and valve rod 1 runs through a butterfly plate 2, butterfly plate 2 is being provided with the semi-circular hole of a symmetry with the corresponding position of semi-circular hole, this two semi-circular hole forms a circular port, insert the pin 3 of fixing this butterfly plate 2 and valve rod 1 in this circular port, the upper and lower end face of butterfly plate 2 respectively is provided with a floor clip 4, and this floor clip 4 passes valve rod 1 and is stuck in the valve body.
In the present embodiment, the cross section of floor clip 4 is circular; The material of floor clip 4 is 304 stainless steels, has certain rigidity, can bear certain power.
The setting of floor clip 4, the fixing sealing station of butterfly plate 2, thus can prevent that valve rod 1 is subjected to unexpected axial force and makes butterfly plate 2 and sealing surface displacement cause the leakage problem of valve.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
