Therefore, the research and use of new tower equipment are of great significance for strengthening the mass transfer process between gas and liquid and industrial production.

[0003] There are openings on the trays inside the existing towers, and valve floats are installed on the edges of the openings. However, the sizes of these openings on the trays cannot be automatically adjusted and cannot change with the change of the gas phase, resulting in irregular distribution of gas in the liquid flow direction. Summary of the Utility Model

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the present utility model provides a guiding floating valve tray with an adjustable opening, and has the following beneficial effects:

[0015] The present utility model has the advantage of automatically adjusting the opening size. When the gas moves upward, it pushes up the floating valve. When the floating valve rotates, the moving pipe moves upward at the same time. When the moving pipe moves, the fixed block is driven to move simultaneously through the fixing rod, so that the fixed block pulls up the telescopic rod, thereby ensuring that the moving direction of the moving pipe does not deviate. The upward movement of the moving pipe drives the air outlet hole to leak out to the outside of the tray, so that the gas can be discharged through the air outlet hole. It can make the floating valve automatically change the opening, and at the same time, the exhaust pressure can be shared through the air outlet hole, solving the problem that the opening size cannot be automatically adjusted and cannot change with the change of the gas phase.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1

[0027] Refer to Figures 1-4 , an adjustable-opening guiding valve tray, including a main body assembly 1; the main body assembly 1 includes a tray 11, and a plurality of valve trays 12 are arranged on the top thereof; each valve tray 12 is provided with an automatic adjustment assembly 2, and each group of the automatic adjustment assemblies 2 includes: a moving pipe 21, arranged at the bottom of the valve tray 12 and inserted into the inside of the tray 11; air outlet holes 22, opened on the outer side wall of the moving pipe 21, a plurality of which are opened and two groups are opened; fixing rods 23, fixedly connected to the inner side wall of the moving pipe 21 and provided with a plurality of them; fixing blocks 24, fixedly connected to the outer side wall of the fixing rods 23; telescopic rods 25, fixedly connected to the bottom of the fixing blocks 24 and the other end fixedly connected to the inner side wall of the tray 11; limiting sleeves 26, fixedly connected to the outer side wall of the moving pipe 21; a sealing sleeve 4 is slidably connected to the outer side wall of each moving pipe 21, and each sealing sleeve 4 is inserted into the inside of the tray 11; a plurality of groups of the air outlet holes 22 are opened.

[0028] When preparing for use, the tray 11 is installed at a designated position. When the gas moves upward, since the valve tray 12 is hinged on the moving pipe 21, the gas jacks up the valve tray 12 upward. When the valve tray 12 rotates, at this time, the moving pipe 21 moves upward at the same time. When the moving pipe 21 moves, it drives the fixing block 24 to move at the same time through the fixing rod 23, so that the fixing block 24 pulls the telescopic rod 25 upward, thereby ensuring that the moving direction of the moving pipe 21 does not deviate. The upward movement of the moving pipe 21 drives the air outlet holes 22 to leak out of the tray 11, so that the gas can be discharged through the air outlet holes 22. While the opening of the valve tray 12 can be automatically changed, the exhaust pressure can be shared through the air outlet holes 22, thereby improving the practicability of the device; a sealing sleeve 4 is slidably connected to the outer side wall of each moving pipe 21, and the sealing sleeve 4 can cover the gap between the moving pipe 21 and the tray 11, thereby preventing the gas from leaking through the gap, thereby improving the stability of the device; a plurality of groups of the air outlet holes 22 are opened, so that when the moving pipe 21 moves to different positions, different numbers of air outlet holes 22 can be exposed, so that the gas can be discharged in time and the exhaust efficiency can be improved.

[0029] Embodiment 2

[0030] Refer to Figures 1-4, an auxiliary function is added on the basis of Embodiment 1;

[0031] An auxiliary component 3 is provided on each of the float valves 12. Each group of the auxiliary components 3 includes: a fixing ring 31 fixedly connected to the outer side wall of the moving pipe 21; a spring 32 disposed on the fixing ring 31 and having two ends fixedly connected to the bottom of the float valve 12 and the top of the fixing ring 31 respectively; a plurality of the springs 32 are provided; and the radius of the float valve 12 is larger than the radius of the moving pipe 21.

[0032] During use, when the air pressure is too high, the gas moves upward to drive the float valve 12 to move upward, thereby driving the spring 32 on the fixing ring 31 to be stretched, so as to prevent the float valve 12 hinged on the moving pipe 21 from completely rotating to the other side and not being automatically closed, thereby improving the stability of the device; a plurality of springs 32 are provided, and the springs 32 can increase the pulling force of the device on the float valve 12 to further prevent the float valve 12 from failing to close normally; the radius of the float valve 12 is larger than the radius of the moving pipe 21, so that the float valve 12 cannot enter the chute required for the sliding of the moving pipe 21, thereby preventing the float valve 12 from rotating and getting stuck in the chute after entering the chute and being unable to open immediately, thereby improving the stability of the device.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
