Abstract
The utility model relates to a tooth type round float valve belonging to the technical field of the chemical industry vapour-liquid mass transfer component. The tooth type round float valve comprises a round valve cover and a valve leg connected with the valve cover vertically, a tongue hole is made at the middle part of the valve cover, a flanging is made at the empty end of the valve leg, dentiform gaps which are arranged at intervals are made at the edge of the circumference of the valve cover, and the position of the dentiform gaps is connected with shim connected with the valve cover vertically. Through improving the shape of the circumference of the valve cover, the tooth type round float valve of the utility model increases the contact area between vapour-liquid phases, thereby improving the mass transfer efficiency between the vapour-liquid phases.
Description
Technical field
The utility model relates to the valve in a kind of chemical reaction tower, especially is loaded on the float valve that is used for gas-liquid phase mass transfer in the reaction tower on the column plate, belongs to chemical industry vapour-liquid mass device technology field.
Background technology
At present, chemical industry vapour-liquid mass tower has been extensive use of valve plate, and one of widely used float valve is circular float valve in valve plate.
Easy rotation when existing circular float valve uses at it the gentle flow point unequal technical problem of loosing that comes off has a lot of improvement.But the applicant finds, converges on the float valve for raising that the float valve architecture advances of exposure level still has leeway between the gas-liquid.
The utility model content
The purpose of this utility model is: propose a kind of tooth-like circular float valve, by improving existing circular float valve structure, realize the increase of the gas phase dispersion area on the float valve, thereby improve the contact area between the gas-liquid that converges on the float valve, and then improve the mass-transfer efficiency between the gas-liquid.
In order to achieve the above object, the solution that the utility model proposes is: a kind of tooth-like circular float valve, comprise circular valve gap, with valve gap valve leg connected vertically, described valve gap middle part is shaped on the tongue hole, described valve leg dead end is shaped on flanging, improvements are, the tooth that is shaped on each interval on the circumferential edge of described valve gap lacks, and described tooth lacks the place and is connected with the shim vertical with valve gap.
During use, tooth-like circular float valve of the present utility model is plugged in (specifically being that the flanging of switching valve leg dead end was about to float valve and is plugged in valve opening after the valve leg was inserted valve opening) in the valve opening of valve plate; After gas enters float valve from valve opening, when the gas that valve opening disperses is separated sheet and further disperses back arrival valve gap top circumference limit around float valve, gas not only disperses finer and closely woven, and, can improve the mass-transfer efficiency between place, the valve gap top circumference limit gas, liquid that converges at float valve thus greatly because of the distribution area that lacks the place at tooth obviously increases gas and the contact area that arrives valve gap top circumference limit liquid stream.
In a word, compare existing circular float valve, tooth-like circular float valve of the present utility model has increased the contact area between the gas, liquid by improving the valve gap peripheral shape, thereby improves the mass-transfer efficiency between the gas, liquid.

The specific embodiment
Embodiment
The tooth-like circular float valve of present embodiment comprises circular valve gap 1 and the valve leg vertical with valve gap 1 as depicted in figs. 1 and 2.The valve leg is by being bent to form with the whole cardinal process sheet that is connected of valve gap 1 periphery; The valve leg has three along circumferentially-spaced, is divided into a standing valve leg 2 and two adjustable valve leg 3-1,3-2; The dead end of standing valve leg 2 is bent along its wide fixedly flanging 4, and the dead end of adjustable valve leg 3-1,3-2 has two adjustable flanging 5-1,5-2 along its leptoprosopy is curved, and the width of standing valve leg 2 is greater than the width of adjustable valve leg 3-1,3-2.In valve gap 1 middle part punching out two tongue holes 6 are arranged, the stepped tooth that is shaped on a plurality of each intervals in the circumferential edge upper punch of valve gap 1 lacks 7, and tooth lacks 7 places and is connected with the shim 8 vertical with valve gap 1, and shim 8 is to be bent to form by the whole tab that connects of valve gap 1 periphery.The end face periphery place of valve gap 1 is a cambered surface.
As shown in Figure 2, to lack 7 be uniformly at intervals on removing valve gap 1 circumferential edge of valve leg outside sentencing to stepped tooth.
When the tooth-like circular float valve of present embodiment is installed, the valve leg inserted valve opening on the valve plate after, adjustable flanging 5-1, the 5-2 of two adjustable valve legs 3 of switching respectively, the float valve that is about to present embodiment is plugged on the valve plate.
When using the tooth-like circular float valve of present embodiment: liquid stream flows through at the upper surface of valve plate, and gas is up walked from the lower surface of valve plate; After gas entered float valve from the valve opening of valve plate, float valve was held up up by gas in liquid stream, and the valve leg is resisted against on the downside wall of valve plate valve opening, and this moment, valve gap 1 end face was near the liquid level of liquid stream; When the gas of valve opening dispersion arrives valve gap 1 top circumference limit, gas promptly lacks distribution along the stepped tooth of valve gap 1 circumferential edge, thereby the gas that disperses from valve opening is further disperseed in valve gap 1 circumferential edge, increase gas and the contact area that flows through valve gap top circumference limit liquid stream thus; React because the gas, liquid on the column plate mainly converges at the place, valve gap top circumference limit of float valve, therefore can improve the mass-transfer efficiency between the gas, liquid on the valve plate greatly.In addition,, can make to flow to flow stream velocity quickening and the sinking that stepped tooth lacks, thereby further promote the mass transfer between the gas, liquid owing to the end face periphery of valve gap 1 is located to be a cambered surface.
Tooth-like circular float valve of the present utility model is not limited to the described concrete technical scheme of the foregoing description, such as, understand easily: 1) valve leg number also can be two or more; 2) valve leg and shim also can be to be connected with valve gap welding or other; 3) the tongue hole count also can be one, two or more; 4) tooth is scarce also can be rectangle, triangle or other shape; 5) tongue hole and tooth are scarce also can be that non-punching press is made, and is cut into as line; 6) tooth lacks along the valve gap circumferential edge also can right and wrong uniform; Or the like.The technical scheme that all employings are equal to replacement or equivalent transformation formation is the protection domain that the utility model requires.
