Problems solved by technology
[0005] At present, although the floating valve tray has been greatly improved in terms of operating flexibility, in production, the applicant found that in industrial production, the air flow rises irregularly, resulting in unsatisfactory treatment of the air flow by the float valve and uneven dispersion of the air flow and insufficient gas-liquid contact

Embodiment
[0018] The tongue type damping valve tray of the present embodiment, as Figure 1 to Figure 4 As shown, it includes a tray 1 and a float valve 2 that can move up and down. The tray 1 is formed with an installation hole for the installation of the float valve. The float valve 2 includes a rectangular valve cover 3 arranged above the tray 1 and a valve leg 4 extending downward from the opposite side edges of the valve cover to the bottom of the tray.
[0019] The bonnet 3 is provided with at least two upwardly arched tongue holes 5 , and the other side edges of the bonnet 3 are provided with downwardly folded serrated edges 6 , the serrated edges 6 of the bonnet are used when the float valve 2 falls. butt against the upper surface of tray 1.
[0020] A ring of protrusions 7 is fixed on the bottom surface of the valve cover 3 , and the tongue hole 5 is located in the ring of protrusions 7 of the valve cover 3 . The circle of protrusions 7 can be a circle of concave protrusions ...

The invention relates to a tongue-shaped damping float valve tray and belongs to the technical field of general physical separation devices. The tongue-shaped damping float valve tray comprises a tray and float valves capable of moving up and down, wherein mounting holes for mounting of the float valves are formed in the tray; each float valve comprises a rectangular bonnet arranged on the tray and valve legs extending downwards from the edges of two opposite sides of the bonnet to be below the tray; at least two upwardly arched tongue holes are formed in each bonnet; downwardly folded saw-toothed edges are arranged on the edges of other two sides of each bonnet; the saw-toothed edges of the bonnets are used for propping against the upper surface of the tray when the float valves fall down; a circle of bulge is fixed on the bottom of each bonnet; the tongue holes are located in the bulge of the corresponding bonnet; an interlayer cavity is formed in each bonnet and filled with damping rubber. The tongue-shaped damping float valve tray has the advantages that airflow is dense and uniform in dispersion and full gas-liquid contact is realized.
Description
technical field [0001] The invention relates to a tray, which belongs to the technical field of general physical separation operation devices. Background technique [0002] Floating valve tower is a new type of tower with simple structure, low manufacturing cost, and can adapt to common material conditions. It is one of the most widely used tower types in chemical and oil refining industries. The performance and technical level of the tower equipment in the valve tower directly affect the output, quality, recovery rate, economic benefits and other aspects of the product. [0003] The float valve tower is characterized by installing a float valve that can move up and down at each mounting hole. When the gas velocity in the installation hole is high, the float valve is lifted up, and when the air velocity is low, the float valve will drop due to its own weight. The lifting position of the float valve is automatically adjusted with the gas flow, so that the gas velocity enter...
