Abstract
The utility model relates to a novel semi-elliptical fixating valve tower plate which flushes out through a tower plate body and comprises a vale face and two valve legs. The projection of the valve face and the two valve legs on the flat surfaces vertical to the tower plate along the direction of fluid flow is semi-elliptic with the focal axis parallel to the tower plate. The projection of the valve face on the tower plate is in the shape of rectangle or trapezium and the periphery of the valve face is straight side or edged side. The valve face is provided with a pilot hole or a micro fixing valve. The airflow passing through the pilot hole can reduce the hydraulic gradient on the tower plate and make the gas-liquid distribute evenly. The micro fixing valve can improve the gas-liquid communication in the top of the value, thereby decreasing the air opposition around the valve and benefiting the improvement of the tower plate efficiency and flux.

The specific embodiment:
Describe the structure of the semiellipse frozen valve tray that the utility model proposes in detail below in conjunction with drawings and Examples.
Embodiment 1: as Fig. 1, the semiellipse frozen valve tray of the utility model design comprises column plate 1 and valve face 2, and valve face 2 is gone out by the body of column plate 1.As Fig. 2, valve face 2 and valve leg 3,4 are projected as semiellipse on the plane vertical with column plate along the liquid flow path direction, and its focal axis is parallel with column plate, and the gap between valve face 2 and the column plate 1 is 3～15 millimeters.Valve face 2 is projected as rectangle or trapezoidal on column plate 1, and the both sides of valve face 2 are straight flange or tooth limit.Can be designed to 4 kinds of structures like this: 1. when valve face 2 being projected as rectangle and valve face both sides and being straight flange on column plate 1, the length of its rectangle is 20～150 millimeters, and width is 10～60 millimeters.2. when valve face 2 being projected as rectangle and valve face both sides and being the tooth limit on column plate 1, the size of its length and width is with 1..3. be projected as trapezoidal and valve face both sides when being straight flange on column plate 1 when valve face 2, its trapezoidal minor face length is 10～50 millimeters, and the long length of side is 20～60 millimeters, and height is 20～150 millimeters.4. be projected as trapezoidal and valve face both sides when being the tooth limit on column plate 1 when valve face 2, its trapezoidal size is with 3..
This structure has been owing to driven pilot hole on valve face 2, in actual production, the small part of gas by pilot hole 7 directly promotes liquid and flows forward, can reduce the gradient of liquid level on the column plate, make uniform gas-liquid distribution, help the reduction of plate pressure drop and leakage, improve the column plate mass-transfer efficiency.
In actual production process, the two-layer slit of gas between valve face 2 and column plate 1 and miniature solid valve 8 valve faces 2 sprays into liquid layer, gas phase is more evenly distributed, reduced the gas speed of valve periphery ejection, the air-flow that has suppressed between valve liquidates, thereby reduced entrainment and plate pressure drop, improved the production upper limit.
The shape on the tooth limit 6 on valve face 2 both sides of the above semiellipse standing valve can be triangle or arc or rectangle or trapezoidal, the 6 pairs of gases in tooth limit have certain peptizaiton, and bubble is diminished, and have improved the uniformity of bubble diameter, can increase the gas-liquid contact area greatly, reach the reinforcement mass transfer.
