Abstract
The utility model provides a kind of sealing flap of check-valves, including pull bar and limb, and the limb is inverted bowl structure, and the pull bar lower end is connected with the limb end face center；The outward flange of the limb is provided with right angle step.In the utility model, right angle step can increase the thickness at limb edge, and then improve the intensity at limb edge, reduce the problems such as abrasion of sealing flap, rupture, deformation, improve service life；Direct step expands the contact area between sealing flap and check-valves, and then improves sealing.
Description
Technical field
The utility model is related to seal technical field, more particularly to a kind of check-valves sealing flap.
Background technology
Check-valves is widely applied to water purifier as a kind of automatic valve, the every field such as air pressure pump.Its operation principle
It is：Under the Fluid pressure effect of a direction flowing, sealing flap is opened, and sucks liquid medium；Liquid medium reverse flow
When, due to the deadweight of Fluid pressure and sealing flap, sealing flap is closed.So as to cut off flowing, playing sealing non-return prevents from being situated between
The effect that matter flows backwards.Pump and the effect that motor is inverted and vessel media is released can be prevented.
Existing check-valves, it seals flap after prolonged exercise folding, seals the edge of flap because friction can be sent out
The problems such as raw abrasion, rupture, deformation, cause sealing to fail, reduce the service life of check-valves.
Utility model content
The technical problems to be solved in the utility model is that there is provided a kind of long service life according to above-mentioned the deficiencies in the prior art
Check valve seal flap.
The technical solution of the utility model is as follows：
A kind of sealing flap of check-valves, including pull bar and limb, the limb are inverted bowl structure, the pull bar
Lower end is connected with the limb end face center；The outward flange of the limb is provided with right angle step.
Further, the pull bar be divided into set from top to bottom pull portion and department of assembly, the department of assembly upper end is set
There is screens bulge loop.
Further, the screens bulge loop top surface is cambered surface, is sideways vertically disposed cylinder, and bottom surface is horizontally disposed
Plane, make the thickness of the screens bulge loop gradually reduces from inside to outside.
Further, the screens bulge loop bottom surface and the corner of the department of assembly are arc angling.
Further, the diameter of the department of assembly is bigger than the diameter for pullling portion.
Compared with prior art, the utility model has the advantages that：（1）Right angle step can increase limb side
The thickness of edge, and then the intensity at limb edge is improved, the problems such as abrasion of sealing flap, rupture, deformation is reduced, raising uses the longevity
Life；（2）Direct step expands the contact area between sealing flap and check-valves, and then improves sealing；（3）Screens is convex
The thickness of ring is gradually reduced from inside to outside, while its intensity is ensured, also reduces the usage amount of raw material, reduction is produced into
This；（4）Arc angling can improve the contact area between sealing flap and accessory, make stress distribution and diffusion uniform, it is to avoid
Stress concentration causes sealing flap to be torn；（5）Department of assembly is relatively large in diameter, and improves the intensity of department of assembly.

Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Type is described in further detail.
As shown in figure 1, the embodiment that the utility model is provided, a kind of sealing flap of check-valves, including pull bar 10 and valve
Piece 20, the limb 20 is inverted bowl structure, and the lower end of pull bar 10 is connected with the end face center of limb 20；Institute
The outward flange for stating limb 20 is provided with direct step 21.Wherein, direct step 21 can increase the thickness at the edge of limb 20, and then
The intensity at the edge of limb 20 is improved, the problems such as abrasion of sealing flap, rupture, deformation is reduced, improves service life；Also, directly
Step expands the contact area between sealing flap and check-valves, and then improves sealing.
In the present embodiment, the thickness of limb 20 is gradually reduced from inside to outside, while intensity also from gradually reducing from inside to outside,
Elastic deformation is sent using the edge of limb 20.
10 points of the pull bar pulls portion 11 and department of assembly 12 for what is set from top to bottom, and the upper end of department of assembly 12 is provided with
Screens bulge loop 13.Wherein, pull bar 10 is used for and the assembling fittings in check-valves.When pull bar 10 is with assembling fittings, department of assembly 12 is inserted
In the mounting hole of accessory, screens bulge loop 13 coordinates with limb 20, limits the activity of department of assembly 12；Pull 11, portion lead
Effect, convenient working person pulls out screens bulge loop 13 mounting hole of accessory.
In the present embodiment, pull the surface of portion 11 and be provided with non-slip texture（It is not drawn into figure）, it is convenient to make for increasing friction
Crawl of the industry person to the portion of pullling 11.
The top surface of screens bulge loop 13 is cambered surface 131, is sideways vertically disposed cylinder 132, and bottom surface is horizontally disposed
Plane 133, make the thickness of the screens bulge loop 13 gradually reduces from inside to outside.Wherein, the thickness of screens bulge loop 13 is from inside to outside
Gradually reduce, while its intensity is ensured, also reduce the usage amount of raw material, reduce production cost.
The bottom surface of screens bulge loop 13 is arc angling 134 with the corner of the department of assembly 12.Wherein, arc angling
134 can improve the contact area between sealing flap and accessory, make stress distribution and diffusion uniform, it is to avoid stress concentration causes
Sealing flap is torn.
The diameter of the department of assembly 12 is bigger than the diameter for pullling portion 11.Department of assembly 12 is relatively large in diameter, and improves dress
Intensity with portion 12, it is to avoid pull bar 10 is pulled off under the stress of accessory.
Above disclosed is only the utility model preferred embodiment, can not limit the utility model with this certainly
Interest field, therefore equivalent variations made according to the utility model claim still belong to the scope that the utility model is covered.
