Abstract
The utility model discloses a butterfly valve sealing component, which comprises a circular sealing ring made of an elastic material, wherein a plurality of circles are arranged on the sealing ring; butterfly valve sealing frameworks are respectively arranged in the circles; and the axes of the circles and the axes of the butterfly valve sealing frameworks are on the same line. The butterfly valve sealing component is made of the elastic material, and inner diameters of the circles are respectively matched with diameters of upper and lower valve shafts of the butterfly valve. During installation, the circles are respectively sleeved on the upper and lower valve shafts before the butterfly valve is connected with the valve shafts, and are arranged on the butterfly valve, radial rings of the butterfly valve sealing frameworks have functions of positioning the butterfly valve sealing ring, and the sealing ring is conveniently installed. The butterfly valve sealing component is used for sealing butterfly valves on a natural gas pipeline and is simple in structure and easy to machine and assemble.
Description
Technical field
The utility model relates to a kind of black box, particularly a kind of butterfly valve seal assembly.
Background technique
Butterfly valve is the valve of 90 degree rotary opening and closings; Butterfly valve has valve body, and there are relative import and export the both sides of valve body, and upper and lower valve shaft is arranged on the valve body; Be connected with butterfly valve between the upper and lower valve shaft in the valve body; Press the relation of the axis and the butterfly valve seal circle center line of valve shaft, butterfly valve has centre-pivoted butterfly valve and eccentric-butterfly-valve, the center line of the axis runout butterfly valve seal circle of eccentric-butterfly-valve valve shaft; The butterfly valve seal circle of eccentric-butterfly-valve can be a ring, and the butterfly valve seal circle of eccentric-butterfly-valve can be that the annular seal circle of elastic material also can be the rigid seal circle of metallic material.Because the axis of centre-pivoted butterfly valve valve shaft is through the center line of butterfly valve seal circle, the butterfly valve seal circle of centre-pivoted butterfly valve can not be the ring identical with the butterfly valve seal circle of eccentric-butterfly-valve.In the existing technology; The butterfly valve seal circle that does not have the ring centre-pivoted butterfly valve; The butterfly valve seal circle is exactly the body of butterfly valve outer periphery, and valve seals is rubber base or the packing element in valve body, and the butterfly valve seal circle of this centre-pivoted butterfly valve makes the design of centre-pivoted butterfly valve sealing pair can not reach quite reasonable; Structure is complicated, processes and assemble cumbersome.
The model utility content
The technical problem that the utility model will solve provides a kind of reasonable in design, and is simple in structure, and processing and assembling are relatively easy to the butterfly valve seal assembly.
For achieving the above object, the technological scheme of the utility model is following:
A kind of butterfly valve seal assembly comprises the annular seal circle of elastic material, and said seal ring is provided with a plurality of annulus, is respectively equipped with the butterfly valve seal skeleton in the said annulus, and the axis of the axis of said annulus and butterfly valve seal skeleton point-blank.
Preferably, the internal diameter of said butterfly valve seal skeleton is identical with the internal diameter of said annulus.
Preferably, the internal diameter of said butterfly valve seal skeleton is greater than the internal diameter of said annulus.
Preferably, the shore a hardness of said seal ring is 76 °.
Preferably, the tensile strength of said seal ring is 15.5MPa.
Preferably, the elongation rate of tensile failure of said seal ring is 210%.
Preferably, the compression set of said seal ring is 20%.
Through technique scheme, the beneficial effect of the utility model is:
The utility model butterfly valve seal skeleton has positioning action to the installation of annular seal circle, and it is reasonable in design, and is simple in structure, and processing and assembling are than being easier to; It is applicable to the natural gas line butterfly valve seal, plays good sealing effect through the tight contact between butterfly valve seal assembly and the butterfly valve.

In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiments of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model sectional view.
The numeral corresponding part title represented among the figure with letter:
10, annular seal circle 11, annulus 12, butterfly valve seal skeleton
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to illustrated in figures 1 and 2; The annular seal circle 10 of a kind of butterfly valve seal assembly of the utility model elastic material; Said seal ring 10 is provided with a plurality of annulus 11; Be respectively equipped with butterfly valve seal skeleton 12 in the said annulus 11, the axis of the axis of said annulus 11 and butterfly valve seal skeleton 12 point-blank.
The internal diameter of the utility model seal ring is 20mm-280mm, and external diameter is 30mm-300mm, and thickness is 5mm-20mm.
The utility model adopts fluorine rubber as material, and it has well acidproof, chemicals-resistant, and the high temperature resistant technical characteristics that waits is applicable to various bad working environment, can play good effect to preventing natural gas leaking.
The internal diameter of the utility model butterfly valve seal skeleton 12 is identical with the internal diameter of said annulus 11, its according to actual needs, the internal diameter of butterfly valve seal skeleton 12 also can be greater than the internal diameter of annulus 11.
In order to reach the standard that national quality detects, the shore a hardness of the utility model seal ring 10 is that 76 °, tensile strength are that 15.5MPa, elongation rate of tensile failure are 210%, compression set is 20%.
More than show and described basic principle of the utility model and the advantage of major character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
