Description
Technical field
The utility model relates to a kind of float valve, belongs to the technical field of chemical that in chemical industry, gas-liquid mass transfer is separated.
Background technology
Plate column is a class for the classification contact mass transfer equipment of gas-liquid or liquid liquid system, by cylindrical-shaped tower and at a certain distance the some column plates of horizontal device in tower form.Be widely used in rectifying and absorption, also can be used as reactor for liquid phase course of reaction.During operation, liquid under gravity, flows through each layer column plate from top to bottom successively, discharges at the bottom of tower; Gas, under pressure differential promotes, from bottom to top successively through each layer column plate, is discharged to tower top.Every block column plate remains the liquid layer of certain depth, gas is distributed in liquid layer by column plate and goes, and carries out phase border contact mass transfer.
Column plate is the position of gas-liquid two-phase contact mass transfer in plate column, and determine the operating characteristics of tower, float valve is the gas phase dispersion component on valve plate; Can float on column plate, change its open degree along with the change of gas flow.
F1 type (also claiming V1 type) valve plate is the most frequently used column plate, but production practices show, in use there is following problem in F1 type float valve: (1), because on column plate, liquid level is different everywhere, when causing float valve to be blown afloat, each float valve is by time of blowing open and caused by the degree varies blown open; (2) air-flow is blown into liquid layer from valve opening surrounding, does not have guidance quality, and liquid foam entrainment increases, and plate efficiency reduces; (3) air pocket bloated from valve opening effectively can not be smashed refinement, makes liquid phase contact mass transfer area little, affects the raising of mass-transfer efficiency; (4) float valve wear phenomenon is serious, and is easy to come off.
Utility model content
The technical problem that the utility model solves is: propose a kind of a kind of rectangular valve that can reduce to rock for the deficiencies in the prior art.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of strip float valve, comprise valve gap and two valve legs of quadrangle, be provided with middle high bottom described valve gap, the projection that surrounding is low, described valve gap is at least provided with a tongue apertures, described valve gap top is provided with the baffle plate be obliquely installed at tongue apertures place, two relative sides of described valve gap are provided with tooth, described valve leg is arranged on bottom valve gap near another two side edge, described valve leg is vertical with valve gap to be arranged, and the lower end of described valve leg is provided with valve pin, and described float valve outer surface is provided with corrosion-resistant finishes.
Being improved to technique scheme: described valve gap is rectangle, the ratio of its long limit and minor face is 2:1, and described tooth is arranged on two long edge positions of valve gap.
Being improved to technique scheme: described tongue apertures has two.
Being improved to technique scheme: described baffle plate and valve gap angle are 20 ° to 30 °.
Being improved to technique scheme: bend bottom described teeth directional valve gap.
The beneficial effects of the utility model are: (1) valve gap is provided with tongue apertures, and when gas velocity is lower, valve gap is closed, and gas sprays by tongue apertures, and bubbling is steady, can reduce float valve vibration; (2) two sides of valve gap are provided with tooth, be separated into much tiny air-flow, reduce the diameter of bubble when gas is bloated, and increase gas liquid interfacial area, and mass-transfer efficiency increases; (3) be provided with centre bottom valve gap high, the projection that surrounding is low, plays guide functions when air-flow blows float valve, is float valve uniform force, not easily rocks; (4) float valve outer surface is provided with corrosion-resistant finishes, extends the service life of float valve.

Be described further of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is the front view of the utility model embodiment one;
Fig. 2 is the top view of the utility model embodiment one;
Fig. 3 is the left view of the utility model embodiment one;
The Reference numeral of above accompanying drawing is: valve gap 1, tongue apertures 11, baffle plate 12, tooth 13, protruding 14, and valve leg 2, valve pin 21.
Detailed description of the invention
Embodiment one
As Fig. 1, the strip float valve of the present embodiment shown in Fig. 2 and Fig. 3, comprise rectangular valve gap 1 and two valve legs 2, be provided with middle high bottom valve gap 1, the projection 14 that surrounding is low, the ratio of the long limit of valve gap 1 and minor face is 2:1, valve gap 1 is provided with two tongue apertures 11, valve gap 1 top is provided with the baffle plate 12 be obliquely installed at tongue apertures 11 place, baffle plate 12 and valve gap 1 angle are 20 ° to 30 °, two long limits of valve gap 1 are provided with the tooth 13 of bending bottom valve gap 1, described valve leg 2 is arranged on bottom valve gap 1 near two minor face places, described valve leg 2 is vertical with valve gap 1 to be arranged, the lower end of valve leg 2 is provided with valve pin 21, float valve surface scribbles corrosion-resistant finishes.
Embodiment two
The strip float valve of the present embodiment, all the other technical characteristics are identical with embodiment one, and difference is: described tongue apertures is provided with three, and baffle plate 12 and valve gap 1 angle are 30 °.
Embodiment three
The strip float valve of the present embodiment, all the other technical characteristics are identical with embodiment one, and difference is: described tongue apertures is provided with four, and baffle plate 12 and valve gap 1 angle are 25 °.
