Background technology
At present, the bivalve butterfly swing check valve connected mode of in the market is connected using wafer type mostly, i.e., in groove connection
, it is necessary to increase connection transfer device in the pipeline system of water route, i.e., wafer type is converted into by plough groove type, to connect bivalve butterfly non-return
Valve.The conversion of such a even mode, increases accessory, complicated, installment work efficiency is low, adds pipeline link cost；And
And pipeline leakage point increases, also be inconvenient to repair.The fix bar of existing bivalve butterfly swing check valve is provided with torsion spring simultaneously, fixed
The semicircular flap of two panels is hinged with bar, the both ends of torsion spring are born against on the outer end end face of flap.Due to there was only torsion spring
Both ends bear against the outer end end face of flap, the area of torsion spring both ends and valve flap contacts is small, makes flap discontinuity, no
Beneficial to the sealing of two panels semicircle flap.How conveniently to realize that bivalve butterfly swing check valve directly connects with the groove pipe fitting in pipeline
Connect, reduce the accessory of pipeline connection, reduce pipeline link cost, improve installment work efficiency；Reduce pipeline connection leakage point, side
Just bivalve butterfly swing check valve pipeline repairs；How to improve the sealing of bivalve butterfly swing check valve is to need to solve the problems, such as.
Utility model content
Technical problem to be solved in the utility model is：A kind of bivalve butterfly swing check valve is provided.Use the bivalve butterfly
Check-valves can not only conveniently be realized and is directly connected with the groove pipe fitting in pipeline, reduce the accessory of pipeline connection, reduced pipeline and connected
This is connected into, improves pipeline installment work efficiency；Pipeline connection leakage point can also be reduced, facilitates bivalve butterfly swing check valve pipeline to tie up
Repair；The sealing of bivalve butterfly swing check valve can also be improved.
The utility model solve above-mentioned technical problem technical scheme be：A kind of bivalve butterfly swing check valve, including valve body, valve
Valve, two symmetrical flaps are movably arranged in valve body using valve shaft, and 2 are provided with the sealing surface being in contact on valve body with flap
Individual arched valve seat, sealing gasket is installed respectively on 2 arched valve seats, it is characterized in that：Valve body both ends outer surface
On be provided with groove, the groove that the valve body both ends are set in appearance can be directly connected using pipe clamp component with groove pipe fitting；Also
Including torsion spring, the torsion spring is arranged in valve body using torsion axis, and the torsion spring has 2 torsion spring supporting legs, 2 flap pressing plates, and this 2
Individual torsion spring leg ends are fixedly connected with 2 flap pressing plates respectively, and 2 flap pressing plate bottom surfaces of the torsion spring are born against
On the outer surface of two flaps；
The sealing gasket is made up of rubber ring and the strip-shaped rubber block being connected with rubber ring both ends, the strip-shaped rubber block and rubber
The connection of rubber ring is connected for arc, and the strip-shaped rubber block that the rubber ring is connected with arc is integrally formed.
The beneficial effects of the utility model are：Due to being provided with groove, valve on the outer surface of valve body both ends of the present utility model
The groove set on the outer surface of body both ends can be directly connected using pipe clamp component with groove pipe fitting.It is direct to realize the utility model
With the connection of groove pipe fitting in pipeline, reduce the accessory of pipeline connection, reduce pipeline link cost, improve pipeline installation
Operating efficiency；The leakage point of pipeline connection is also reduced, facilitates the maintenance of pipeline；Set on other the utility model torsion axis
2 flap pressing plate bottom surfaces of torsion spring bear against on the outer surface of two flaps；2 flap pressing plate bottom surfaces of torsion spring
Increase with the area of 2 valve flap contacts, make 2 flap uniform forces, be advantageous to the sealing of 2 flaps, overcome existing bivalve
The both ends of butterfly swing check valve torsion spring only have end points bear against flap outer end end face be unfavorable for flap sealing the defects of, improve
The sealing of the utility model bivalve butterfly swing check valve.
, should again because the utility model sealing gasket rubber ring and the strip-shaped rubber block being connected with rubber ring both ends by being made up of
The connection of strip-shaped rubber block and rubber ring is connected for arc, and the strip-shaped rubber block that the rubber ring is connected with arc is integrally formed.
The risk of leak at flap is eliminated, makes flap reliable with valve base sealing.
