Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of safety check of reinforced seal performance.
Background technique
Safety check is also known as check valve, one-way valve or check valve, refer to and rely on medium itself to flow and automatic open and close flap, be used for the valve preventing medium from flowing backwards, its effect prevents the function safety check of the medium directional flow in pipeline and unlikely refluence to belong to self-acting valve class, be mainly used on the pipeline of medium one-way flow, medium is only allowed to flow to a direction, to try to avert accidents.The auxiliary system that safety check also can be used for may being raised above system pressure to pressure wherein provides on the pipeline of supply.Safety check mainly can be divided into Swing check valve (rotating according to center of gravity) and Lift check valve (moving along axis).In existing safety check, general structure is embedded on flap by soft seal circle, then be fixed on by flap on rocking bar and form motive sealing with valve seat.But safety check is operationally due to the long-term souring of medium, rocking bar there will be slight loosening, and makes the motive sealing deleterious between flap and valve seat, reveals quantitative change large, is unfavorable for the use of operating mode.
Model utility content
Therefore, in order to solve prior art Problems existing, the utility model provides a kind of safety check of reinforced seal performance.
For solving this technical problem, the utility model takes following scheme: a kind of safety check of reinforced seal performance, comprise valve body, valve gap, flap and rocking bar, described valve gap is located at the upper opening place of valve body, described valve body is provided with the fluid passage of through medium fluid vertically, described fluid passage has water intake and water outlet, between water intake and water outlet, valve seat is provided with in described valve body, described flap can the sealing of folding be located on valve seat, described rocking bar is by the rotating top being located at described valve seat in valve body of rotating shaft, the free end of described rocking bar is circular and is connected with flap, described valve seat is provided with the annular protrusion coaxial with it, described flap is respectively equipped with relative to the upper and lower two ends, that side of valve seat the annular groove matched with described annular protrusion, described flap is then provided with a plurality of annular groove coaxial with it back to that side in valve seat.
Further improvement: be bolted between the upper opening place of described valve gap and valve body, and be provided with seal washer between described valve gap and the upper opening place of valve body.
Further improvement: described annular groove is curved surface groove.
Further improvement: the making material of described valve body and valve seat is nickel.
The beneficial effects of the utility model are: the utility model by arranging curved surface occlusion structure between flap and valve seat, effectively strengthen the sealability of flap and valve seat, and the special cirque structure of rocking bar free end can effectively prevent flap be out of shape and affect its sealing, flap is provided with multiple annular groove back to the side in valve seat simultaneously, compared with the smooth surface of existing flap, quite set up stiffening rib, improve its impact resistance in the duct, increase the service life, especially annular groove is curved surface groove, stress can be reduced from structure to concentrate, strengthen flap intensity, and the snap-in force that also can strengthen under water impact between flap and valve seat.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the cross section structure schematic diagram of described flap.
Fig. 3 is the plan view of described flap.
