As the graphics that Fig. 1 and Fig. 2 is this multi-functional butterfly valve butterfly plate, the diameter 2400mm of what the diameter of this butterfly plate was got is standard flange formula soft sealing butterfly valve butterfly plate.Because the design of this butterfly plate can be carried out completely on three-dimensional drawing software, and do not have complicated especially unmanageable structure, the utility model can utilize the 3D printing technique of current advanced person to carry out production and processing completely.
Working principle of the present utility model and working procedure as follows:
1) in butterfly valve body cylindrical channel, rotated around axis by butterfly plate keying operating mechanism and the multi-functional butterfly plate be connected between upper lower valve rod thereof, angle of swing is that between 0 ° ~ 90 °, when rotating to 90 °, valve is then in full-gear.In the process that butterfly valve is opened, butterfly plate can depart from valve seat gradually, owing to not having the effect of the power of Vertical direction between butterfly plate and valve seat, thus the frictional heat substantially reduced between sealing pair, reduce wearing and tearing, decrease operation moment of torsion, because this reducing the energy needed for valve plate keying.
2) when fluid is from butterfly valve import one side inflow, open and close the upper lower valve rod of operating mechanism rotation by butterfly plate and open this multi-functional butterfly plate, fluid can by the flow manifold on the arch hemisphere jut of butterfly plate both sides and arch hemisphere jut, this hemisphere jut can reduce the high speed of fluid jet, and the flow manifold of hemisphere jut both sides can shunting decompression.
The selfsealings of butterfly valve energy can be made by the block of both sides flow manifold, due to both sides flow manifold number not etc., so gravity is different suffered by the final block formed, when butterfly valve opening/closing mechanism lost efficacy, selfsealings effect can be reached by automatic impaction under gravity.
3) along with the rotation of lower valve rod on butterfly valve, butterfly plate corner increases, the utilization ratio of the flow manifold on the arch hemisphere jut of butterfly plate both sides also will increase, and when butterfly plate is in 90 ° of standard-sized sheets, reduce the effect of fluid by flow velocity during butterfly plate by reaching a kind of stable shunting decompression.
4) when butterfly plate is closed, due to the difference of flow manifold quantity on the arch hemisphere jut of butterfly plate both sides, compress the sealability that valve seat can increase valve, and when applied external force lost efficacy, still enough can keep sealability.
The butterfly valve butterfly plate that electric planer formula axle construction of the present utility model is improved, when flowing medium flows through butterfly valve by valve plate one side runner, on butterfly plate both sides arch hemisphere jut and both sides arch hemisphere jut, the different flow manifold of distributed quantity can play the effect of deceleration and shunting decompression, and this deceleration and shunting decompression act in the whole working procedure of butterfly valve and all can exist.Substantially slow down and eliminate when fluid flows through butterfly valve and the high speed impact of butterfly valve butterfly plate and pipeline is worn and torn.When butterfly valve cuts out completely, the sealability of butterfly valve effectively can be strengthened.Therefore, this butterfly plate with encircleing hemisphere jut and flow manifold, further increases the working life of butterfly valve, improves the performance of its entirety, ensures that long-time the continuing of butterfly valve uses.
