Abstract
The utility model relates to a diaphragm pump cover plate which comprises a bottom part and an opening part, wherein a connecting part between the bottom part and the opening part is arranged into an arc surface shape; the arc-surface-shaped connecting part protrudes firstly and then concaves from the bottom part to the opening part; an installation hole is formed in the middle of the bottom; a ring is arranged on the periphery of the opening part; and the cross section of the ring is round. The diaphragm pump cover plate is mounted on a pneumatic diaphragm pump, so that the diaphragm pump cover plate can be fully contacted with components which are matched with the diaphragm pump cover plate; and in a specific usage process of the diaphragm pump cover plate, the sealing effect is good, so that gas leakage of the pneumatic diaphragm pump is effectively avoided.
Description
Technical field
The utility model relates to a kind of component of machine of membrane pump with pneumatic drive, is specifically related to a kind of diaphragm pump cover plate.
Background technique
Membrane pump with pneumatic drive is a kind of Novel conveyer tool, and it adopts pressurized air is power source, for various corrosive liquids, with the liquid of particle, high viscosity, volatile, inflammable, hypertoxic liquid all can be taken out light and be exhausted, formation production at present, quality of product is well received.The component that it is installed and used on diaphragm pump require the cooperation between each component to have good sealing.The edge of its opening portion of diaphragm pump cover plate that uses at present is list structure, and this makes the diaphragm pump cover plate can not fully contact with other component, thereby makes poorly sealedly, causes gas leakage.
The model utility content
The utility model purpose is that a kind of diaphragm pump cover plate is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of diaphragm pump cover plate, comprise bottom and opening portion, and the joint between described bottom and opening portion is arranged to arc surfaced, and described arc surfaced joint first protruding recurve from the bottom to the opening portion; The place, neutral position of described bottom is provided with mounting hole; The edge of described opening portion is provided with ring, and the cross section of described ring is rounded.
Preferably, on described joint, annular array has some stiffening ribs.
Preferably, be provided with protuberance on described bottom, and described protuberance is arranged on the periphery of mounting hole.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The described diaphragm pump cover plate of the utility model scheme, because the edge of described opening portion is provided with ring, and the cross section of described ring is rounded, when being installed to it on membrane pump with pneumatic drive, can with the component that match between fully contact; Make it in the concrete process of using, good sealing effect, and then effectively avoided the gas leakage of membrane pump with pneumatic drive.
Description of drawings
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of diaphragm pump cover plate described in the utility model;
Accompanying drawing 2 is the sectional view of diaphragm pump cover plate described in the utility model;
Wherein: 1, bottom; 2, opening portion; 3, joint; 4, mounting hole; 5, ring; 6, stiffening rib; 7, protuberance.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As accompanying drawing 1,2 described diaphragm pump cover plates of the present utility model, comprise bottom 1 and opening portion 2, the joint 3 between described bottom 1 and opening portion 2 is arranged to arc surfaced, and described arc surfaced joint 3 from the bottom 1 to the opening portion 2 protruding recurves of elder generation; The place, neutral position of described bottom 1 is provided with mounting hole 4; The edge of described opening portion 2 is provided with ring 5, and the cross section of described ring 5 is rounded.
On wherein said joint 3, annular array has some stiffening ribs 6; Be provided with protuberance 7 on described bottom 1, and described protuberance 7 is arranged on the periphery of mounting hole 4.
Diaphragm pump cover plate described in the utility model is because the edge of described opening portion 2 is provided with ring 5, and the cross section of described ring 5 is rounded, when being installed to it on membrane pump with pneumatic drive, can with the component that match between fully contact; Make it in the concrete process of using, good sealing effect, and then effectively avoided the gas leakage of membrane pump with pneumatic drive.
Be only below concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, within all dropping on the utility model rights protection scope.
