Description
Technical field
The utility model relates to the buoyancy tank flap valve, especially the box-shaped door body of buoyancy tank flap valve.
Background technique
At present, the various pipelines and the water channel road that are used for rivers bank, municipal water supply draining and sewage treatment project.And the sewage pumping station pipe outlet, various vertical shaft well lids need the flap valve of overflow or fluid stopping.Common common flap valve, counterweight flap valve, buoyancy tank flap valve only play unlatching, closing function, the effect extreme difference.Especially export in the various pipelines and the water channel road of large-scale pumping plant, municipal water supply draining and sewage treatment project.Common common flap valve, counterweight flap valve, buoyancy tank flap valve all are that single door body rotates around hinge, carry out opening and closing, reach overflow or fluid stopping.Noise was big when flow was big, when frequency is fast, formed resonance, and the opposite house body is destructive big.Therefore common flap valve exists the noise that produces when closing big, and the counterweight flap valve exists sealing not tight, and there is the big problem of duct pressure loss in the buoyancy tank flap valve.
The model utility content
The purpose of this utility model is exactly that the noise that produces when solving common flap valve and closing is big, and counterweight flap valve sealing is not tight, and the problem that buoyancy tank flap valve duct pressure loss is big provides a kind of bivalve formula buoyancy tank flap valve.
The technical solution adopted in the utility model is: bivalve formula buoyancy tank flap valve, it comprises the flap valve seat and is used for closing the box-shaped door body of flap valve seat, box-shaped door body is movably connected on the flap valve seat, described flap valve seat end face is the inclined-plane, it is characterized in that described box-shaped door body is that epivalve box-shaped door body is hinged with hypovalve box-shaped door body and constitutes together, the interior hole end surface of described flap valve seat is provided with the footpath plate that is used for cooperating box-shaped door body, the footpath plate is positioned at hinged of two box-shaped door bodies to be located, and the end face of flap valve seat is provided with and suitable epivalve seal ring that is used for sealing of two box-shaped door bodies and hypovalve seal ring.
Adopt technique scheme, be hinged with hypovalve box-shaped door body and constitute together because box-shaped door body is an epivalve box-shaped door body, when box-shaped door body is closed the flap valve seat, hypovalve box-shaped door body will at first rotate around epivalve box-shaped door body, two box-shaped door bodies are closed the flap valve seat gradually, play buffer function, therefore can directly not impact the flap valve seat, epivalve box-shaped Men Tiyu epivalve seal ring cooperates realizes that sealing, hypovalve box-shaped Men Tiyu hypovalve seal ring cooperate the realization sealing.
For hypovalve box-shaped door body is rotated carry out spacing, the described hypovalve box-shaped door body back side is provided with outwardly directed hypovalve box-shaped door body limiting stopper, make hypovalve box-shaped door body rotate the back side of extruding epivalve box-shaped door body when upwards digging, the angle of hypovalve box-shaped Men Tiyu vertical curve is 65 degree.The extruding of hypovalve box-shaped door body limiting stopper when fluid passes through the flap valve seat, hypovalve box-shaped door body rotated like this, owing to will reach position-limiting action.
Carry out spacingly for epivalve box-shaped door body is rotated, the back side of described epivalve box-shaped door body also is provided with epivalve box-shaped door body limiting stopper, makes epivalve box-shaped door body rotate the end face of extruding flap valve seat when upwards digging, and the angle of epivalve box-shaped Men Tiyu vertical curve is 50 degree.Epivalve box-shaped door body rotates the end face of extruding flap valve seat when upwards digging like this, thereby can reach spacing.
The utility model beneficial effect is: because the utility model one is the bivalve structure; The 2nd, floating box structure is when producing buoyancy to box-shaped door body during flowing water in the flap valve seat, so easily open.When current come, hypovalve box-shaped Men Tixian opens, be rotated around down hinge, when rotating to 65 °, hypovalve box-shaped door body limiting stopper touches epivalve box-shaped door body, drives epivalve box-shaped door body and rotates simultaneously, when epivalve box-shaped door body is opened to 50 °, epivalve box-shaped door body limiting stopper carries out spacing, reaches the full open state.Hypovalve box-shaped door body differential seat angle on this moment＜20 degree.When closing, the forward current reduce, and oppositely water level increases, reverse water pressure increases, pipeline internal upper part drawdown, epivalve box-shaped Men Tixian is rotated down and closes, in rotary course, drive when hypovalve box-shaped door body is opened and be rotated down, because epivalve box-shaped door body is shorter than hypovalve box-shaped door body stroke, gravity is earlier greater than buoyancy, so close earlier, along with water level in the pipeline descends downwards, hypovalve box-shaped door body is closed subsequently gradually.Thereby play the effect of fluid stopping successively.Thereby it is big to satisfy opening angle, and impact force is little when closing, and noise is little, and stagnant water effect is good; Duct pressure loss is little, reduces requirements such as starting of pump station power.
