Description
Technical field
It the utility model is related to valve technology field, more particularly to a kind of rubber slab check-valves.
Background technology
Check-valves is for preventing the medium from flowing backwards, preventing that pump and drive motor from being inverted and vessel media is released
Valve.Check-valves is a kind of automatic valve, and it flows and automatic open and close valve flap in itself by medium.
DRV is to increase noise-reducing structure in the check valve, is hit to eliminate fluid hammer sound and valve flap
The operation sound of valve body.DRV includes the check-valves of spring return type and the check-valves of turnover plate type flap.Prior art
In turnover plate type check-valves be typically in turnover panel flap outer cladding rubber layer, by using rubber layer reduce check-valves operation sound
Sound.
But the turnover panel flap weight in the cladding in existing turnover plate type check-valves after rubber layer is heavier, one section is being used
Time, particularly difference variation is big, applying working condition is poor occasion, the easy aging of turnover panel flap in cladding after rubber layer deform,
Cause the non-return sealing effectiveness of turnover panel flap to be deteriorated, have impact on the performance of turnover plate type check-valves.
The content of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of non-aging deformation, service life length, non-return
Seal operation is reliable, the rubber slab check-valves of non-return good sealing effect.
The utility model is that technical scheme is used by reaching above-mentioned technical purpose：A kind of rubber slab check-valves, including
Check valve body and the turnover panel flap being arranged in check valve body, the turnover panel flap include turnover panel skeleton and rubber coated
Layer, wherein the enhancing grid for being easy to be combined with rubber adhesive is provided with the turnover panel skeleton, on the outer ring of the turnover panel flap
The flexible sealing air bag of annular is had additional, the fluid input side of the turnover panel flap is provided with auxiliary seal response agency, described auxiliary
Help in sealing response agency and be provided with a hinge-rod, one end of the hinge-rod is hinged on the downside of the turnover panel flap, described
The other end of hinge-rod connects an auxiliary and replys weighted spherical ball, and the auxiliary, which is replied in weighted spherical ball, is provided with topping up chamber, the topping up
Match somebody with somebody heavy-fluid filled with smaller than the Media density flowed through in valve body in chamber.
The separate gasbag chamber of two or more is provided with the flexible sealing air bag, filled with indifferent gas in the gasbag chamber
Body.
The pressure of inert gas in the gasbag chamber is 0.15-0.3MPa.
The outer ledge of the flexible sealing air bag is provided with transition seal shirt rim.
Seal groove is additionally provided with the sealing surface of the check valve body, sealing ring, the sealing are provided with the seal groove
The diameter of circle is less than the diameter of the flexible sealing air bag.
The beneficial effects of the utility model are：
1st, the flexible sealing air bag of annular is set up on the outer ring of turnover panel flap, indifferent gas is filled in flexible sealing air bag
Body, the characteristic of crimp is more favorable for using flexible sealing air bag, enables the close of flexible sealing air bag and check valve body
The even closer contact of front cover, ensure the non-return sealing effectiveness of turnover panel flap；
2nd, turnover panel flap side sets auxiliary seal response agency again, when fluid input side liquid is reduced, auxiliary seal
Auxiliary in response agency replys weighted spherical ball under gravity, and turnover panel flap can be made to accelerate to reset, it is ensured that non-return sealing is dynamic
Make reliably, and during the unlatching of turnover panel flap, auxiliary is replied weighted spherical ball and acted without interference with turnover panel flap, does not interfere with valve performance；
In a word, the utility model turnover panel valve flap structure is stable, and non-aging deformation, turnover panel flap non-return seal operation can
Lean on, non-return good sealing effect, can use steadily in the long term.
