Abstract
The utility model discloses an integral type diaphragm fills up, including gasket and a plurality of fixed heads of setting on the gasket, the gasket is equipped with external seal circle, inside seal circle and sets up the sealed recess between external seal circle and inside seal circle, the fixed head includes clamping part and connecting portion, the neck that the clamping part was equipped with the bellying and was connected with connecting portion, form the draw -in groove between bellying and the neck, the fixed head is the integrated into one piece structure with the gasket. The utility model discloses a gasket is the integrated into one piece structure with the fixed head to is connected through fixed head and compression wheel, need use bridge screw fixed connection, consequently do not have the stress concentration problem, stopped unfamiliar pad completely because the problem of leaking of productions such as becoming flexible is connected to the bridge screw.
Description
Technical field
The utility model relates to diaphragm pump accessory technical field, particularly a kind of unitary diaphragm pad.
Background technique
Diaphragm pump is a kind of form comparatively special in displacement pump, and it is agitating back and forth and changing swept volume of a single chamber to suck and discharge liquid of a dependence barrier film pad.Barrier film spacer has good toughness and corrosion resistance, the liquid be inhaled into and discharge liquid is separated, and when barrier film pad is to driving mechanism motion, is that negative pressure sucks liquid, when barrier film pad moves to another side, then discharges liquid in pump chamber during work.Usually in diaphragm pump, be provided with one group of active chamber, traditional diaphragm pump structure adopts follower bolt barrier film pad and compression wheel to be fastenedly connected, and follower bolt easy loose or dislocation in the long-term operation process of diaphragm pump, and the joint of follower bolt and barrier film pad can exist stress concentration phenomenon, long time running all easily causes diaphragm pump to leak.
Model utility content
Adopt that follower bolt mode is fixing easily causes diaphragm pump to leak water problem for solving existing barrier film pad and compression wheel, the utility model discloses a kind of unitary diaphragm pad, comprise pad and be arranged on the multiple glands on pad, described pad is provided with exterior seal ring, inner seal ring and the sealed groove be arranged between exterior seal ring and inner seal ring, described gland comprises clamping part and joint, the neck that described clamping part is provided with lug boss and is connected with joint, draw-in groove is formed between described lug boss and neck, described gland and pad are formed in one structure.
As further improvement of the utility model, described pad is the triangular structures of three drift angles through circular arc chamfering process, and described pad is provided with three glands, and described three glands are separately positioned on three drift angle places of triangle pad.
As further improvement of the utility model, described pad is provided with three stiffening ribs, and three glands are separated by described three stiffening ribs respectively.
As further improvement of the utility model, described lug boss is circular cone shape structure, and described neck is circular cone shape structure.
As further improvement of the utility model, described joint is circular arc planar structure.
As further improvement of the utility model, the height of described inner seal ring is lower than exterior seal ring.
The beneficial effects of the utility model are:
Pad of the present utility model and gland are formed in one structure, and be connected with compression wheel by gland, do not need to use follower bolt to be fixedly connected with, therefore there is not problem of stress concentration, stopped barrier film pad completely and loosened the seepy question waiting and produce because bridge screw connects.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 2 is the structure rear view of the utility model embodiment;
Fig. 3 is the partial sectional view along A-A face in Fig. 2.
Mark in figure: 1-pad; 11-exterior seal ring; 12-inner seal ring; 13-sealed groove; 14-stiffening rib; 2-gland; 21-clamping part; 211-lug boss; 212-neck; 22-joint.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.
As shown in Figure 1 to Figure 3, unitary diaphragm pad, comprises pad 1 and is arranged on three glands 2 on pad 1, and gland 2 and pad 1 are formed in one structure.The sealed groove 13 that pad 1 is provided with exterior seal ring 11, inner seal ring 12 and is arranged between exterior seal ring 11 and inner seal ring 12, the height of inner seal ring 12 is lower than exterior seal ring 11.
Pad 1 is provided with three stiffening ribs, 14, three stiffening ribs 14 and three glands 2 is separated respectively.
Pad 1 is the triangular structures of three drift angles through circular arc chamfering process, and three glands 2 are separately positioned on three drift angle places of triangle pad 1.
Gland 2 comprises clamping part 21 and circular arc planar joint 22, the circular cone shape neck 212 that clamping part 21 is provided with circular cone shape lug boss 211 and is connected with joint 22, forms draw-in groove between lug boss 211 and neck 212.
Pad of the present utility model 1 and gland 2 are formed in one structure, and be connected with compression wheel by gland 2, do not need to use bridge screw to be fixedly connected with, therefore there is not problem of stress concentration, stopped barrier film pad completely and loosened the seepy question waiting and produce because bridge screw connects.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
