Abstract
The utility model discloses a flat plate steel gate with a balancing hole. The balancing hole is formed in the middle lower portion of the gate and penetrates in two sides of the gate; a cavity is formed in the balancing hole in the gate and is communicated with the balancing hole; a gate valve is arranged in the cavity; the gate is connected with a shaft head through a shaft; the shaft head is fixed on a sleeve; the sleeve is connected with a guiding bearing through the shaft; the guiding bearing is connected with a rotary shaft head and is fixed on the top of the gate valve through the sleeve; and the rotary shaft head is arranged outside the top of the gate valve. The flat plate steel gate with the balancing hole has the advantages that the flat plate steel gate is easy to manufacture, convenient to mount and easy to operate; when the gate is required to be lifted up, the gate valve can be opened, and the water level of the left of the gate is level with the water level of the right of the gate by using the balancing hole; and when the gate is required to be closed, the gate valve can be closed, water cannot leak from the gate, and a high isolation effect can be achieved.
Description
Technical field
The utility model relates to the balance pipe on the contact gate of two water inlet flow channels of circulating pump room in steam power station secondary cycle expanding unit water system processed.
Background technology
In secondary cycle expanding unit water system processed, two water inlet flow channels of circulating pump room are provided with contact gate, when the cooling tower of a unit or circulating water pump maintenance, need the water in cooling tower and circulating water pump forebay be drained by submersible pump.For not affecting the operation of an other unit, need close this gate; When cooling tower or the complete need of circulating water pump maintenance are mentioned this gate, because gate one lateral water pressure is larger, on gate, watertight rubber bar and contact surface frictional force are larger, cause headstock gear hoisting capacity larger.For reducing to open headstock gear hoisting capacity, on steel gate, be provided with balance pipe, before mentioning steel gate, first open balance pipe, after gate left and right sides water level maintains an equal level, when gate two lateral water pressures equate, on gate watertight rubber bar will with the effect of contact surface zerofriction force, the headstock gear of now mentioning steel gate only needs to provide the hoisting capacity that overcomes gate dead weight.The balance pipe of the utility model setting is comprised of gate valve, connection spindle nose, sleeve pipe, axle, guide bearing, rotating shaft head; When cooling tower or circulating water pump maintenance, need close this balance pipe.When cooling tower or circulating water pump maintenance is complete need to mention gate time, need open this balance pipe.
Summary of the invention
The purpose of this utility model is to provide a kind of plate steel gate with balance pipe, and this device can guarantee that gate left and right sides water level maintains an equal level and blocks the effect of left and right sides current.
The technical solution of the utility model is: a kind of plate steel gate with balance pipe, this device gate middle and lower part is provided with balance pipe, balance pipe runs through the both sides of gate, gate inner equilibrium hole is provided with cavity, cavity and balance pipe connect, and be provided with gate valve, gate and by axle, connect that spindle nose, spindle nose are fixed on sleeve pipe, sleeve pipe is connected with guide bearing by axle in cavity, and guide bearing is connected with rotating shaft head, guide bearing is fixed on gate valve top by sleeve pipe, and rotating shaft head is outside gate valve top.
The utility model has the advantage of that making is simple, easy for installation, processing ease, in the time will mentioning gate, can open gate valve, by balance pipe, guarantees that gate left and right water level maintains an equal level; When wanting closed shutter, can closing gate valve, thus guarantee that gate is water-tight, play good buffer action.
Accompanying drawing explanation
Fig. 1 is a kind of plate steel gate structural representation with balance pipe of the utility model;
Fig. 2 is the utility model A-A sectional view.
The specific embodiment
A kind of plate steel gate with balance pipe, this device gate middle and lower part is provided with balance pipe, balance pipe runs through the both sides of gate, gate inner equilibrium hole is provided with cavity, cavity and balance pipe connect, and be provided with gate valve 1, gate valve 1 and by axle, connect that spindle nose 2, spindle nose 2 are fixed on sleeve pipe 3, sleeve pipe 3 passes through axle 4 and is connected with guide bearing 5 in cavity, and guide bearing 5 is connected with rotating shaft head 6, guide bearing 5 is fixed on gate valve 1 top by sleeve pipe 3, and rotating shaft head 6 is outside gate valve 1 top.
In the time will mentioning gate, utilize special T-shaped spanner, rotate rotating shaft head, the rotation by axle, sleeve pipe transfers torque on the central axis of lower side gate valve, thereby drives the rising of flashboard in gate valve, opens balance pipe, guarantees that gate left and right water level maintains an equal level; When wanting closed shutter, need make the flashboard in gate valve decline, block current, and do not seep water.
Gate valve adopts the valve of nominal diameter 300mm, and material is ductile iron; Connecting spindle nose material is 45#(plating zinc on surface nickel alloy); Sleeve pipe material is Q235(plating zinc on surface nickel alloy); Axial wood matter is 45#(plating zinc on surface nickel alloy); Guide bearing material is 45#(plating zinc on surface nickel alloy); Rotating shaft head material is 45#(plating zinc on surface nickel alloy).
