More than the height of short valve leg, the centre position of valve block is provided with rectangle pilot hole, and valve block upper surface corresponds to rectangle guiding hole site and set
There is guiding cavity, be oriented to cavity and set perforate towards long valve leg direction, long valve leg middle and lower part is provided with a square pod apertures, valve block
It is respectively arranged on the left side and the right side the serrated edge tilted down.
The width of a kind of described single-sided rectified tooth edge float valve, the width of the long valve leg and the width of short valve leg than valve block
It is narrow.
The advantages of the utility model is with effect：
1. simple in construction, easy to use, cost is low, easily manufactured, can punching press completion.The rectangle float valve is placed in
It is circumferentially fixed in the valve opening of column plate, it is difficult for drop-off when in use.
2. the rectangle float valve can with gas phase load difference and freely up and down float, fraction via valve face guiding
Hole, which enters, is oriented to cavity, the gas turns in directed cavity body, sprays into column plate liquid layer from the pilot hole towards long valve leg, makes on valve block
Gas-liquid two-phase cocurrent, gas phase promote liquid phase flowing, reduce gradient of liquid level and tower tray pressure drop, flux increase.More importantly this
Kind float valve solves the deficiency that traditional float valve upper end has mass transfer dead band, and plate efficiency greatly improves.
3. the rectangle float valve valve block side is the serrated edge rolled over downwards, gas is set to be divided into perhaps when flowing out float valve side opening
Multiply little airflow, so as to increase gas-liquid contact specific area, improve column plate mass-transfer efficiency；After serrated edge is bent downwardly, a part
Gas is encountered when passing through float valve sprays into liquid layer between float valve after serrated edge with direction obliquely, and another part gas then passes through tooth
Between space float valve top liquid layer is sprayed into diagonal upward direction so that the Local Gas Holdup of between float valve and float valve top liquid layer tends to
Unanimously, operational stability is improved；
4. being provided with pilot hole in long valve leg, when gas phase load is larger, float valve floats upwards, the square on long valve leg
Pod apertures are opened, and gas is blown out from square pod apertures, are further promoted the liquid flowing on column plate, are eliminated the dead of mass transfer
Area, reduce gradient of liquid level；When gas phase load is smaller, float valve sinks, and square water conservancy diversion bore closure, no longer sprays gas, no
The adverse effect for blowing thin liquid layer can be produced.
5. the rectangle float valve when gas phase load variations are larger, can adjust the gas by float valve by the floating of valve leg
Stream, so as to improve mass-transfer efficiency；And the height of two valve legs is different, so as to adapt to different gas phase loads, adds operation bullet
Property, reduce column plate resistance.
