Abstract
The utility model relates to a grid-type float valve column tray. Straight-leg float valves are evenly arranged in the valve holes of a column tray, two symmetric grids are arranged above the float valves, and each pair of grids are installed parallel with the direction of liquid stream. The floating upward opening of the float valves is determined by the length of the sleeve pipes sheathed and clamped between grid plates and a column tray, and each sleeve pipe is connected and fixed by bolts. When gas phase stream is blown out of the valve holes of the column tray, the float valves are blew to rise, liquid phase stream is blown out, simultaneously straight shaped valve legs act guiding functions, and the symmetric grids of the upper parts of the float valves act the positioning function of preventing the float valves from being blown off.
Description
The utility model relates to a kind of chemical industry equipment, particularly a kind of grid type floating valve tray.
Float valve tray has obtained using widely in chemical industry, refining equipment, and it mainly contains V-type, A type and crux.The V-type float valve mainly by with the match valve gap of buckle closure and constituted by one and down protruding valve leg of tower tray valve opening with valve gap, in order to prevent that float valve from being gone out the valve opening position by stripping, therefore the valve leg is designed to have crooked shape, so that with valve opening along engaging, promptly prevent float valve by stripping, guarantee the operate as normal of float valve.But because float valve will bear the impulsive force of rising vapour phase stream to it in the course of the work, this impulsive force then acts directly on the crooked valve leg, time one is long, then caused the wearing and tearing of valve leg to fracture or curvedly become the back and cause the stripping of float valve, float valve then causes the serious leakage of valve opening and the efficient of tower tray greatly to reduce after by stripping.
In order to address this problem, people have designed a kind of cross type float valve, and cross promptly is installed above valve opening, preventing the stripping of float valve, but the manufacturing of cross type float valve, install than the V-shaped valve complexity many, so fail to be widely adopted always.
The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of existing in prior technology, and a kind of grizzly bar that is provided with above float valve is provided, and float valve is difficult for stripping, the grid type floating valve tray of long service life.
The purpose of this utility model is to realize by following technical scheme, in the valve opening of tower tray, all be placed with straight-leg float valve, the top of float valve is provided with two symmetrical grizzly bars, each is installed grizzly bar and liquid flow path direction are suitable mutually, the come-up aperture of float valve is determined by the casing length that cover is sandwiched between screen and the tower tray, each sleeve pipe is connected and fixed by bolt, when the valve opening of gas phase outflow tower tray blows out, float valve has been blowed floating, liquid phase stream blows out, at this moment, straight shape valve leg play the guiding role, and the symmetrical grizzly bar on float valve top then works the position-limiting action that prevents the float valve stripping.
Therefore remarkable result of the present utility model is:
1. the setting of screen had both prevented that dashing of float valve from taking off, and did not hinder the proper flow of vapor phase stream again.
2. installation is simple, its aperture is adjustable, is applicable to the float valve of different size.
3. float valve is easy for installation, need not to bend the valve leg, long service life.
Concrete structure of the present utility model is realized by the following examples and accompanying drawing thereof.
Fig. 1 is a section of structure of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is the expanded view of float valve among Fig. 1.
Be described in detail below in conjunction with 1～3 pair of concrete structure of the present utility model of accompanying drawing:
The utility model has tower tray 6, on tower tray 6, offer valve opening 61, at each valve opening 61 built-in float valve 5 that are placed with, it is characterized in that: above float valve 5, be provided with grizzly bar 1, be provided with thimble 4 between grizzly bar 1 and the tower tray 6, connecting bolt 2 passes tower tray 6, thimble 4 and grizzly bar 1 back and by nut 3 three is locked and connected, the protruding vertical valve leg 51 that has with valve opening 61 mutually movable plug-in mountings under float valve 5 peripheral intervals.Referring to Fig. 1 to Fig. 3
Architectural feature of the present utility model also is:
Have one to float and open apart from 7 between grizzly bar 1 bottom of the top of float valve 5 and its top, grizzly bar 1 is what to be symmetrically the top that is disposed on float valve 5, and to flow flow direction identical for be provided with direction and the liquid of grizzly bar 1.Referring to Fig. 1 and Fig. 2
Operation principle of the present utility model is:
When air-flow is upwards impacted extremely down by tower tray 6 bottoms, float valve 5 is by the jack-up that makes progress, the float valve 5 that is lifted is owing to be subjected to the restriction of the grizzly bar 1 of its top, do not taken off so can not dash, the float valve leg 51 of upright shape then plays radially spacing guide effect, make float valve 5 vertically rise reliably or to descend, to guarantee the normal operation of float valve tray with liquid stream.
If need to change the specification or the increase of float valve or reduce its aperture, then bolt can be unloaded, the thimble that wears different length again gets final product.
Claims (2)
1, grid type floating valve tray, tower tray 6 is arranged, on tower tray 6, offer valve opening 61, at each valve opening 61 built-in float valve 5 that are placed with, it is characterized in that: above float valve 5, be provided with grizzly bar 1, be provided with thimble 4 between grizzly bar 1 and the tower tray 6, connecting bolt 2 passes tower tray 6, thimble 4 and grizzly bar 1 back and by nut 3 three is locked and connected, the protruding vertical valve leg 51 that has with valve opening 61 mutually movable plug-in mountings under float valve 5 peripheral intervals.
2, according to the described grid type floating valve tray of claim 1, it is characterized in that: unsteady opening apart from 7 arranged between grizzly bar 1 bottom of the top of float valve 5 and its top, grizzly bar 1 is what to be symmetrically the top that is disposed on float valve 5, grizzly bar 1 that direction is set is identical with liquid stream flow direction.
