Abstract
The utility model discloses a top-mounted butterfly valve, which comprises a valve bonnet, a valve body, a valve stem, a butterfly plate and a support. A sealing device arranged between the butterfly plate and the valve body includes a butterfly plate sealing ring, an adjusting ring, an adjusting screw, a sealing ring pressing plate and a pressing plate screw, wherein the butterfly plate sealing ring is arranged between the butterfly plate and the valve body, the adjusting ring arranged in the butterfly plate is abutted to the butterfly plate sealing ring and outwardly squeezes the butterfly plate sealing ring, the contact surface of the adjusting ring with the butterfly plate sealing ring is inclined, the sealing ring pressing plate presses the outer side of the butterfly plate sealing ring and is fixed to the butterfly plate by the aid of the pressing plate screw, and the adjusting screw penetrating through the sealing ring pressing plate is in linkage with the adjusting ring in a matched manner. When in maintenance, the adjusting screw is adjusted to drive the adjusting ring to move, and the adjusting ring squeezes the butterfly plate sealing ring along the contact inclined surface of the adjusting ring with the butterfly plate sealing ring, so that the butterfly plate sealing ring expands outwardly, the outer diameter of the butterfly plate sealing ring is changed, and then the purpose of repairing the size of a sealing surface of the sealing device can be achieved.
Description
Technical field
The utility model relates to a kind of butterfly valve, especially a kind of dress formula butterfly valve of going up.
Background technique
The opening and closing of last dress formula butterfly valve are that the center centers on valve rod and rotates and realize by butterfly plate with the valve rod at body cavity mainly, because butterfly plate is in rotation status for a long time, and when medium when body cavity is flowed through, also can wash away butterfly plate, seal arrangement between butterfly plate and the valve body is squeezed, so the seal arrangement between butterfly plate and the valve body is easy to generate loosening or damages, the damage of seal arrangement will directly influence the sealability of valve, so need timing seal arrangement is keeped in repair, and the existing dress formula butterfly valve of going up, its seal arrangement is exactly seal ring usually, and the seal ring close-fitting is not quick detachable in the butterfly plate draw-in groove.During maintenance, usually whole valve need be disassembled from pipeline, or sever the work that pipeline on the pipeline is finished maintenance, this has brought very large workload for the maintenance work personnel, has also caused inconvenience in the routine work and loss economically to the user.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of sealability better, and is easy to dismounting, can realize the last dress formula butterfly valve of on-line maintenance.
For achieving the above object, the utility model provides a kind of dress formula butterfly valve of going up, comprise valve gap, valve body, valve rod, butterfly plate, support, the upper-end surface and the support of valve gap are connected and fixed, the lower end surface and the valve body of valve gap are connected and fixed, valve rod is located in the valve body, butterfly plate is located in the inner chamber of valve body, be connected with valve rod one end, and described butterfly plate can be that the center centers on the valve rod rotation with the valve rod at body cavity, be provided with seal arrangement between butterfly plate and the valve body, described seal arrangement comprises the butterfly plate seal ring, adjust circle, adjusting screw, the seal ring pressing plate, bridge screw, the butterfly plate seal ring is located between butterfly plate and the valve body, and adjust circle and be located in the butterfly plate, and inconsistent with the butterfly plate seal ring, outwards push the butterfly plate seal ring, the seal ring pressing plate is pressed in the butterfly plate seal ring outside, and fixes by bridge screw and butterfly plate, and adjusting screw is passed the seal ring pressing plate and cooperated interlock with the adjustment circle.
The surface of contact that the utility model can further be set to described adjustment circle and butterfly plate seal ring is the inclined-plane.
The beneficial effects of the utility model are: adopt said structure, during maintenance, by adjusting adjusting screw, adjusting screw drives to adjust to enclose and moves, and adjusts circle along pushing the butterfly plate seal ring with the inclined-plane that contacts of butterfly plate seal ring, and the butterfly plate seal ring is expanded outwardly, change the outside dimension of butterfly plate seal ring, can reach the purpose of repairing the seal arrangement size of seal contact face, such maintenance mode is convenient and swift, and significantly reduces maintenance cost.
Description of drawings
Fig. 1 is a structure sectional view of the present utility model;
Fig. 2 is the I portion enlarged view of Fig. 1.
Embodiment
As Fig. 1, provided a kind of dress formula butterfly valve of going up shown in 2, comprise valve gap 1, valve body 2, valve rod 3, butterfly plate 4, support 5, the upper-end surface of valve gap 1 and support 5 are connected and fixed, the lower end surface of valve gap 1 and valve body 2 are connected and fixed, valve rod 3 is located in the valve body 2, butterfly plate 4 is located in the inner chamber of valve body 2, be connected with valve rod 3 one ends, and described butterfly plate 4 can be that the center is around valve rod 3 rotations with valve rod 3 at valve body 2 inner chambers, be provided with seal arrangement 6 between butterfly plate 4 and the valve body 2, described seal arrangement 6 comprises butterfly plate seal ring 61, adjust circle 62, adjusting screw 63, seal ring pressing plate 64, bridge screw 65, butterfly plate seal ring 61 is located between butterfly plate 4 and the valve body 2, adjusting circle 62 is located in the butterfly plate 4, inconsistent with butterfly plate seal ring 61, outwards push butterfly plate seal ring 61, and described adjustment circle 62 is the inclined-plane with the surface of contact 621 of butterfly plate seal ring 61, seal ring pressing plate 64 is pressed in butterfly plate seal ring 61 outsides, and fixing with butterfly plate 4 by bridge screw 65, adjusting screw 63 is passed seal ring pressing plate 64 and is cooperated interlock with adjustment circle 62.
During maintenance, by adjusting adjusting screw 63, adjusting screw 63 drives adjustment circle 62 and moves, adjust circle 62 along pushing butterfly plate seal rings 61 with the inclined-plane 621 that contacts of butterfly plate seal ring 61, butterfly plate seal ring 61 is expanded outwardly, change the outside dimension of butterfly plate seal ring 61, can reach the purpose of repairing seal arrangement 6 sizes of seal contact face, such maintenance mode is convenient and swift, and significantly reduces maintenance cost.
