In recent years, people have designed and developed some novel valve platies at the shortcoming of circular valve plate, and bar shaped (rectangle) valve plate as U.S. Nutter design has overcome the phenomenon that circular valve plate float valve in operation rotates; The Varioflex-Valve column plate of Germany Stahl company, " stuck " phenomenon has been avoided in the lifting flexibly of its valve block, and operating flexibility also improves a lot; The major defect that the guide float valve tray of China development and trapezoidal float valve tray have not only overcome circular valve plate, and its performance surpassed the rectangular valve column plate has in some aspects increased on the column plate gas to the impetus forward of liquid; The trapezoidal float valve tray with guide effect that University Of Tianjin designs and develops is integrated in one the advantage of guide float valve tray and trapezoidal float valve tray, makes this effect obtain further reinforcement.
The purpose of this utility model is that maintenance has the advantage of the trapezoidal float valve tray of guide effect, designs a kind of novel two unsteady trapezoidal float valve tray on this basis.This column plate is not only the same with the trapezoidal float valve tray with guide effect to have reliable in structure, and gradient of liquid level is little on the column plate, even does not have the liquid level gradient, liquid dispersion is little, the all even plate efficiency advantages of higher of no stagnation region, distribution of gas, and the operating flexibility of column plate is greatly improved.
Main design philosophy of the present utility model is:
1. two unsteady trapezoidal float valve tray are made of two unsteady trapezoidal float valves and column plate, and two trapezoidal float valves that float are made of the trapezoidal float valve of perforate on the valve block and the little float valve that fluctuates that is installed on the trapezoidal float valve valve block.
2. trapezoidal float valve adopts trapezoidal valve block, to keep trapezoidal float valve tray and to have the advantage of the trapezoidal float valve tray of guide effect.
3. offer trapezoidal valve opening on the column plate, the axis of trapezoidal valve opening is identical with liquid main flow direction on the column plate or constitute one less than 90 ° acute angle, and the short base of valve opening is facing to the exit weir of column plate.After two trapezoidal float valves that float were installed on the column plate, gas constituted an acute angle from the both sides ejection of float valve with liquid main flow direction on the column plate in operation, promotes liquid and flows forward, to reduce liquid level drop and liquid dispersion.
4. one or more little valve openings are set on trapezoidal valve block, the little float valve of various types can be installed in the little valve opening, as floating (work) tongue, trapezoidal float valve, trapezoidal float valve with guide effect, rectangular valve, guide float-valve, oval float valve, circular float valve, the triangle float valve, Hy-Contact valve, or the like.
5. two trapezoidal float valves that float can mix use with the float valve of other types on same column plate, constitute the Composite floating valve column plate, as two trapezoidal float valves that float are installed in the arch area of column plate, rectangular valve etc. are installed in the main flow district; Also can on same column plate, all use two trapezoidal float valves that float,, reduce liquid dispersion, improve plate efficiency to eliminate the stagnation region on the column plate.
6. in operating process, when gas speed was low, the little float valve on the trapezoidal float valve sheet was at first along with the increase of gas speed is opened gradually, after little float valve complete opening reaches maximum elevate a turnable ladder height, along with the further increase of gas speed, trapezoidal float valve is just opened gradually, until reaching its maximum elevate a turnable ladder height; Perhaps, when gas speed was low, trapezoidal float valve was along with the increase of gas speed is at first opened, and reached its maximum elevate a turnable ladder height, and after gas speed further increased, the little float valve on the trapezoidal float valve sheet was just opened gradually, until reaching its maximum elevate a turnable ladder height.The opening sequence of large and small float valve is decided according to different requirements, can be decided by the different-thickness of valve block.
According to above-mentioned main design philosophy, the inventor has designed a kind of two unsteady trapezoidal float valve tray, accompanying drawing is to be that floating tongue is the local diagrammatic sketch of a kind of two unsteady trapezoidal float valve tray of example with the little float valve on the trapezoidal float valve sheet, as example the utility model is specifically described:
