Abstract
The utility model relates to a bidirectional auto-sealing non-leakage high-temperature butterfly valve. On a butterfly plate and a pressing ring of the existing butterfly valve, the utility model is respectively provided with a circle of inner end surface and annular elastic sheets which are fixedly connected with the butterfly plate and the pressing ring, and a sealing ring is arranged between the annular elastic sheets. Simultaneously, the axial directions of the butterfly plate and the pressing ring are provided with a plurality of through holes which are connected with the annular elastic sheets. A compound conical sleeve is fixedly arranged on the inner wall of a valve body, an annular containing cavity (a) which is communicated with the outside is formed between the compound conical sleeve and steps on the inner wall of the valve body. The other side of the compound conical sleeve is also provided with an annular containing cavity (b) which is communicated with the outside through an annular through groove (s) of the bottom end of the compound conical sleeve. The utility model has the advantages of simple structure and reliable sealing performance, and is suitable for being used as a stop valve and a regulation valve in conveying the high temperature and pressure fluid.
Description
The utility model relates to a kind of High Temperature High Pressure metal hard-sealing butterfly valve.Refer in particular to a kind of two-way from motive sealing leak-free high temperature butterfly valve.
At home in the prior art for example the patent No. be that the sealing principle of 882122800 wafer type metal hard-sealing butterfly valves is forced seal, its sealability is understable, more can not realize not having leaking, under the condition of high temperature, sealability is more unreliable.
The purpose of this utility model be to overcome the deficiency of prior art and provide a kind of simple in structure, easy to use, that elevated-temperature seal is reliable for effect is two-way from the leak free high temperature butterfly valve of motive sealing.
The utility model is to adopt following proposal to realize: be provided with two steps on existing butterfly valve butterfly plate exterior edge face, big footpath step is provided with the cyclic spring sheet (B) that a circle interior edge face and dish plate are connected, seal ring is installed on the cyclic spring sheet (B), the trim ring downside also is provided with on cyclic spring sheet (A) that circle interior edge face and a trim ring be connected and the path step that is installed in butterfly plate, simultaneously, be axially arranged with some through holes (g) that link to each other with cyclic spring sheet (B) in the step upper edge, big footpath of butterfly plate, at the some through holes (f) that link to each other with annular elastomeric shape sheet (A) of axially also being provided with of trim ring, the end of compound conical sleeve one side is installed on the inwall of valve body, the sealing station of conical sleeve and seal ring is matched, form a ring-shaped chamber (a) between the step that is provided with on while and the valve interior wall.This ring-shaped chamber (a) is in communication with the outside by some through holes (d) of being located on compound conical sleeve one end and the step, and the opposite side of compound conical sleeve also is provided with a ring-shaped chamber (b) and is in communication with the outside by the annular through groove (s) of being located at compound conical sleeve bottom.
Be elaborated below in conjunction with the concrete structure of accompanying drawing to model utility:
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the A-A sectional view of accompanying drawing 1.
See also accompanying drawing 1,2, the utility model is made up of drive unit (1), heat-insulating base (2), valve body (3), butterfly plate (4), seal ring (5), major axis (10), minor axis (11), trim ring (6), compound conical sleeve (7), axle sleeve (8), pin (12).Major axis (10) one ends connect by heat-insulating base (2) and drive unit (1), the other end is packed into by the last hole internal axle sleeve (8) of valve body (3) in butterfly plate (4) the projection hole, minor axis (11) one ends are packed in the axle sleeve (8) of valve body (3), pack into major axis (10) in the dish plate hole, minor axis (11) all uses pin (12) fixing, butterfly plate (4) exterior edge face is circular, two steps are arranged on the exterior edge face, big footpath step is provided with the cyclic spring sheet (B) that a circle interior edge face and dish plate are connected, seal ring (4) is installed on the cyclic spring sheet (B), trim ring (6) downside also is provided with on cyclic spring sheet (A) that circle interior edge face and a trim ring (6) be connected and the path step that is installed in butterfly plate (4), simultaneously, be axially arranged with some through holes (g) that link to each other with cyclic spring sheet (B) in the step upper edge, big footpath of butterfly plate (4), at the some through holes (f) that link to each other with annular elastomeric shape sheet (A) of axially also being provided with of trim ring (6), the end of compound conical sleeve (7) one sides is installed on the inwall of valve body (3), the conical sleeve (7) and the sealing station of seal ring are matched, form a ring-shaped chamber (a) between the step (9) that is provided with on while and valve body (3) inwall.This ring-shaped chamber (a) is in communication with the outside by some through holes (d) of being located on compound conical sleeve (7) one ends and the step (9), and the opposite side of compound conical sleeve (7) also is provided with a ring-shaped chamber (b) and is in communication with the outside by the annular through groove (s) of being located at compound conical sleeve (7) bottom.
Working principle of the present utility model is summarized as follows: when the utility model is in closed state, be in the liquid medium of High Temperature High Pressure of any side of butterfly plate, to make the utility model produce following action: at first to enter in butterfly plate or the trim ring and contact with annular shell fragment B, A along axial hole g, f on dish plate or the trim ring, make annular shell fragment distortion, seal ring (5) is compressed with shell fragment B, A point of contact h, j, realize sealing; Simultaneously, the high-temperature high-pressure liquid body medium enters respectively among thin-walled cavity volume b, a through annular opening s and through hole d again, and thin-walled m, the n extruding of compound conical sleeve (7) is rotated around the r point, and the point of contact h of thin-walled m and seal ring (5) is adjacent to, and realizes inclusion seal.The utility model is owing to adopt said structure, thereby changes in the prior art forced seal for from motive sealing, and can be high pressure resistant, and pressure is high more, and sealing effect is good more.
In sum, the utility model is simple in structure, and manufacturing is easy, and is easy for operation, and sealability is reliable, be suitable for as in the pipelines such as metallurgy, thermoelectricity plant, chemical industry, district heating system, when making conveyance fluid by, modulating valve usefulness.
