Abstract
The utility model discloses a pneumatic diaphragm, including the discoid diaphragm body, be equipped with the annular groove on the annular medial surface of the diaphragm body, be equipped with a plurality of endocentric circular shapes in the annular groove and prevent the fold strengthening rib, prevent the fold strengthening rib for every ring and prevent by the curved of a plurality of interval distribution that fold rib section constitutes respectively. The utility model discloses simple structure, reasonable in design prevents the fold strengthening rib through setting up in the arc recess to to prevent that the fold strengthening rib falls into the little arc rib of a plurality of, and make the diaphragm body more soft, improve pull resistance and intensity, prevent the fold, satisfy the user demand of enterprise.
Description
Technical field:
The utility model relates generally to pneumatic diaphragm pump technical field, relates in particular to a kind of pneumatic diaphragm sheet.
Background technology:
Diaphragm in pneumatic diaphragm pump is the main working parts of pneumatic diaphragm pump, and pneumatic diaphragm pump is to utilize diaphragm that the pump housing is separated into two cavitys, a fluid chamber and an air chamber. The centre position of diaphragm is to connect central shaft, is transported to the power that the compressed air in pneumatic diaphragm pump provides, and acts on diaphragm by central shaft, and diaphragm is swung.
Diaphragm in prior art in use, easily fold, and pull resistance is bad, need to improve its structure.
Utility model content:
The utility model object is exactly the defect in order to make up prior art, and a kind of pneumatic diaphragm sheet of reasonable in design is provided.
The utility model is achieved through the following technical solutions:
A kind of pneumatic diaphragm sheet, it is characterized in that: the membrane body that includes dish type, the annular inboard face of membrane body is provided with annular groove, in annular groove, be provided with some concentric circular anti-fold reinforcements, the anti-fold reinforcement of every circle is made up of the anti-fold rib section of multiple arcs spaced apart respectively.
A kind of pneumatic diaphragm sheet, is characterized in that: the medial surface of membrane body is provided with conical cavity, the annular outer rim of described membrane body is retainer ring, between described membrane body conical cavity and retainer ring, is provided with arc-shaped transition portion.
A kind of pneumatic diaphragm sheet, is characterized in that: described annular groove is positioned at arc-shaped transition portion.
A kind of pneumatic diaphragm sheet, is characterized in that: the annular inboard face of described retainer ring is provided with circular tensile-resistant reinforcing rib, and tensile-resistant reinforcing rib is that the anti-lacing wire bar of the arc spaced apart by multistage forms.
Described anti-fold rib section is 2/5ths segmental arc of respective circular.
The radian of described membrane body is in 20 degree.
The utility model has the advantages that:
The utility model is simple in structure, reasonable in design, by anti-fold reinforcement is set in arc groove, and anti-fold reinforcement is divided into several little arc ribs, makes membrane body more soft, improve pull resistance and intensity, prevent fold, met the user demand of enterprise. Situ cleaning, disinfect in situ, can be used for laboratory.
Brief description of the drawings:
Fig. 1 is front view of the present utility model.
Fig. 2 is side view of the present utility model.
Detailed description of the invention:
Referring to accompanying drawing.
A kind of pneumatic diaphragm sheet, include the membrane body 1 of dish type, the annular inboard face of membrane body 1 is provided with annular groove 2, is provided with some concentric circular anti-fold reinforcements 3 in annular groove 2, and the anti-fold reinforcement 3 of every circle is made up of the anti-fold rib section of multiple arcs spaced apart respectively.
Membrane body 1 center is provided with diaphragm core 8, and the annular outer wall of diaphragm core 8 is provided with groove.
The medial surface of membrane body is provided with conical cavity 4, and the annular outer rim of described membrane body is retainer ring 5, between described membrane body conical cavity and retainer ring, is provided with arc-shaped transition portion 6.
Described annular groove 2 is positioned at arc-shaped transition portion.
