Abstract
The utility model discloses a sealing ring of an eccentric butterfly valve, which comprises an annular ring, wherein a continuous groove is arranged around the ring, and the diameter of the plane of an upper edge of the groove is larger than that of the plane of a lower edge of the groove. The sealing ring of the eccentric butterfly valve is a valve seat so that the structure of the valve can be simplified. In addition, the sealing ring is simple in structure, convenient to mount and debug, fine in sealing effect and high-temperature-resistant.
Description
Technical field
The utility model relates to a kind of valve seal ring, particularly a kind of seal ring that is used for eccentric-butterfly-valve.
Background technique
Existing eccentric-butterfly-valve seal ring mainly is to be made by rubber-like materials such as rubber or plastics, for reduce eccentric-butterfly-valve open, wearing and tearing when closing between butterfly plate and seal ring, reduce friction torque, realize sealing and permanent sealing.The groove processing industry that is used at present seal ring on valve body, valve seat is difficult, installs and inconvenient debugging, and it is bigger particularly to seal elastic compensating effect difference on effect under different pressure uses.
Summary of the invention
Because the problems referred to above that prior art exists the utility model proposes a kind of eccentric-butterfly-valve seal ring, 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 seal ring, comprise an annular circle body, have a continuous recess, and the diameter on the plane at the place, upper edge of this groove is greater than the diameter on this plane, place, groove lower edge round this circle body.
As further feature of the present utility model, eccentric-butterfly-valve seal ring material is a stainless steel.
Because adopt above technological scheme, eccentric-butterfly-valve seal ring of the present utility model is valve seat, can simplify the structure of valve; Simple in structure, be convenient to install and debugging; Good airproof performance and high temperature resistant.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is a plan view of the present utility model.
Among the figure: 1, annular circle body; 2, groove; 3, plane, place, upper edge; 4, plane, place, lower edge.
Embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawings below:
As depicted in figs. 1 and 2, a kind of eccentric-butterfly-valve seal ring comprises an annular circle body 1, has a continuous recess 2 round this irregular annular circle body 1, and the diameter on the plane, place, upper edge 3 of this groove 2 is big and the diameter on plane, place, lower edge 4.With reference to Fig. 2, be the plan view of eccentric-butterfly-valve seal ring of the present utility model, its two ends are one " L " shape.
Plane, place, lower edge of the present utility model 4 directly contacts butterfly plate, is pressing a gland on the plane, place, upper edge 3.
In the present embodiment, eccentric-butterfly-valve seal ring material is 304 stainless steels, has certain intensity, and not yielding, high temperature resistantly and anti-pulls long service life.
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.
Claims (2)
1. an eccentric-butterfly-valve seal ring is characterized in that: comprise an annular circle body, have a continuous recess round this circle body, and the diameter on the plane at the place, upper edge of this groove is greater than the diameter on this plane, place, groove lower edge.
