Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
See shown in Fig. 5 to Figure 11, according to embodiment of the present utility model, the cooperating structure of diaphragm and piston valve cover comprises diaphragm 1 and piston valve cover 2, diaphragm 1 is provided with sealing fin 3, piston valve cover 2 upper cover is provided with and the sealed groove 4 sealing fin 3 interference fit, and sealing fin 3 successively decreases along the cross section, direction away from diaphragm 1.
Diaphragm 1 is by realizing being tightly connected between sealing fin 3 and the sealed groove 4 of piston valve cover 2, by sealing the changes of section of fin 3, the sealability between diaphragm 1 and piston valve cover 2 can be improved, avoid occurring gap when coordinating between sealing fin 3 and the sealed groove 4 of piston valve cover 2, the cross section increased gradually by sealing fin 3 realizes coordinating with the excellent sealing between sealed groove 4, produces the problem of the seepage between hydroecium after preventing diaphragm 1 long-play.
In one drawing in unshowned embodiment, sealing fin 3 is trapezoidal projection 6, and sealed groove 4 is trapezoidal groove.In the process that diaphragm 1 and piston valve cover 2 coordinate, along with pressing down of trapezoidal groove, gap between trapezoidal groove and trapezoidal projection 6 diminishes gradually, coordinate when piston valve cover 2 completes with diaphragm 1, now formed between the side of trapezoidal groove and the side of trapezoidal projection 6 and closely cooperate, thus prevent the cooperation of diaphragm 1 and piston valve cover 2 from occurring gap and seepage problem occurs.
