Further, the cushion layer is made of rubber.
(III) beneficial effects
Compared with the prior art, the utility model has the following beneficial effects:
the grooves 6 are symmetrically arranged at the front end and the rear end of the butterfly plate 5 in a rotating way, so that the built-in activities of the two side ends of the butterfly plate 5 are correspondingly realized, and the material use of the valve body 1 is reduced; the cushion layer 7 at the inner side of the groove 6 is attached to the butterfly plate 5 to provide a sealing effect; and a veneer for blocking the butterfly plate 5 from rotating anticlockwise is arranged on the inner side of the groove 6 to provide support for preventing the butterfly plate 5 from rotating excessively.
Drawings
Other features, objects and advantages of the present utility model will become more apparent upon reading of the detailed description of non-limiting embodiments, given with reference to the accompanying drawings in which:
FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a schematic diagram of another embodiment of the present utility model;
in the figure: valve body-1, connecting pipe-2, valve cover-3, valve rod-4, butterfly plate-5, groove-6, cushion layer-7 and annular groove-8.
Detailed Description
Referring to fig. 1 and 2, the present utility model provides a groove butterfly valve with good sealing performance: comprises a valve body 1 (which is a butterfly valve main body);
the opposite ends of the valve body 1 are respectively provided with a connecting pipe 2 (used for connecting a circulating component);
the outer side of the connecting pipe 2 is provided with an annular groove 8 to form a groove butterfly valve for groove type installation;
a valve cover 3 is fixedly arranged at the top end of the valve body 1, two ends of the top and bottom of the valve cover 3 are sealed by a valve rod 4 (the inner side of the valve cover is provided with a part for providing the sealing of the valve rod 4) and extend into the inner side of the valve body 1, and the other end of the valve rod 4 extends out of the outer side of the valve body 1 and is connected with a rotating part (a hand wheel and the like);
the bottom end of the valve rod 4 is fixedly connected with a butterfly plate 5, wherein the butterfly plate 5 is hermetically rotated on the inner side of the valve body 1;
grooves 6 are symmetrically formed in the front end and the rear end of the butterfly plate 5 in a rotating mode, the grooves are formed in the inner side of the valve body 1, the butterfly plate 5 moves on the inner side of the grooves 6, peripheral sealing ends of the butterfly plate 5 are arranged in the grooves 6 in a built-in mode, and therefore material usage of the valve body 1 is reduced;
