In the petroleum field, the float valve tray is widely used in the petrochemical industry, especially in the distillation and extraction process. In terms of the types of float valve packing, there are two types: whole block type and block type. According to the different tower diameters, choose the appropriate float valve tray form. For example, when the tower diameter is generally 300-800mm, the whole block type is used; when the tower diameter is greater than 800mm, the block type can be used. In addition, different types of float valve packings also have different characteristics. For example, some types of float valve packings have advantages in separation efficiency, processing capacity, shedding and blocking.

[0003] The prior art has the following technical problems:

[0005] 2. Float valve packing is generally fixed with bolts during installation, which makes it inconvenient to install multiple float valve packings. The position of adjacent float valve packings is difficult to adjust after installation, which is not conducive to actual installation and adjustment. Utility Model Content

[0023] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0024] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0026] Reference Figure 1-4 A multi-stage controlled float valve packing device comprises a packing body 1 and a mounting ring 3. The packing body 1 is provided with a mounting ring 3 at its outer edge. The surface of the mounting ring 3 is penetrated with a mounting screw 8. Adjacent packing bodies 1 are connected by the mounting screw 8. The surface of the mounting ring 3 is provided with a mounting screw groove 9. The mounting screw groove 9 is threadedly connected to the surface of the mounting screw 8. The surface of the mounting screw 8 is threadedly connected with a positioning nut 4. When the whole device is actually installed and used, the vertical installation height between adjacent packing bodies 1 is mainly achieved by the mounting screw 8. The end of the mounting screw 8 is inserted into the bottom The mounting groove 9 on the surface of the mounting ring 3 of the filler body 1 at the bottom is inserted and positioned by rotation, and then the circumferential mounting screws 8 are inserted and positioned in turn. Then, the positioning nut 4 is inserted and positioned according to the installation position. Finally, the filler body 1 at the top is directly vertically inserted through the mounting groove 9 without rotation. The thread between the mounting groove 9 and the mounting screw 8 meets the size requirement that can be directly inserted under vertical force. Then, the positioning nut 4 is inserted until it is against the surface of the top filler body 1, and the vertical installation between adjacent filler bodies 1 is completed.

[0027] When the gas is actually used for diversion, since the surface of the filler body 1 is provided with fan-shaped guide arc grooves 5 distributed circumferentially, a float valve body 6 is provided between adjacent fan-shaped guide arc grooves 5, and the float valve body 6 gradually increases from the center to the edge of the filler body 1, a diversion groove 2 is opened at the vertical corresponding position of the filler body 1 and the float valve body 6, and limiting legs 7 are provided at both ends of the bottom surface of the float valve body 6, and the side of the limiting legs 7 is against the side of the diversion groove 2. When the gas circulates, it enters upward through the bottom of the filler body 1 and enters through the guide groove. The impact force of the gas pushes the float valve body 6 engaged with the surface of the diversion groove 2 upward to open the diversion groove 2, and the gas can enter the top surface of the filler body 1 along the opened gap. The liquid separated from the gas that contacts the surface of the float valve body 6 and the surface of the filler body 1 is retained and remains on the surface of the filler body 1. It can circulate along the fan-shaped guide arc groove 5 on the surface of the filler body 1 to achieve diversion of the separated liquid.

[0028] Other limiting structures of the entire device are as follows: the top surface of the packing body 1 is an arc surface, the end of the fan-shaped guide arc groove 5 penetrates the edge of the packing body 1, and the fan-shaped guide arc groove 5 is a blind groove. The arc surface structure allows the gas and liquid to flow faster due to the influence of gravity, thereby improving the flow efficiency. The float valve bodies 6 on the surface of the packing body 1 with the same circumferential size are the same size, and the top surface of the float valve body 6 is fan-shaped. The edges of the float valve bodies 6 between adjacent circumferences of the surface of the packing body 1 are collinear, the edges of the float valve bodies 6 are all rounded, the edges of the surface of the packing body 1 are rounded, and the bottom surface of the packing body 1 is an arc surface. Specific embodiment 2:

[0030] Reference Figure 1-4 In order to facilitate the installation between multiple packing bodies 1, in actual use, the mounting screw groove 9 on the surface of the mounting ring 3 can be set as a through groove, and the inner wall is not provided with threads, and can directly slide up and down along the mounting screw 8. During installation, the upper and lower bottom surfaces can be positioned by the positioning nut 4 on the surface of the mounting screw 8. This method is more conducive to the rapid installation of the packing body 1. Specific embodiment three:

[0032] Reference Figure 1-4 When the packing body 1 is actually used, different gas diversion flow rates are controlled by the distribution position of the float valve body 6. The gas is circulated by setting float valve bodies 6 of different sizes on adjacent circles, so that the flow groove at the position where the larger float valve body 6 is located is relatively large, and the gas circulation volume is larger, but the upward lifting force of the gas required to lift the float valve body 6 is larger. When the gas enters along the bottom surface of the packing body 1, it is first pushed up along the center position, and at the same time, it moves to both sides along the arc surface of the bottom surface of the packing body 1 and pushes upward, so as to achieve coverage and diversion flow of the entire packing body 1 and prevent gas flow accumulation.

[0033] In summary:

[0034] 1. A plurality of fan-shaped guide arc grooves 5 are arranged on the arc-shaped surface circumference of the filler body 1 to divert the gas entering the top surface, and to divert and gather the accumulated liquid after gas-liquid separation, so as to prevent liquid accumulation and accelerate liquid flow. At the same time, different sizes of float valve bodies 6 are arranged within the adjacent circumference of the surface of the filler body 1 to divert and divert the filler body 1 from the center to the edge to different degrees, effectively preventing gas accumulation, accelerating gas flow, and realizing multi-stage control. The structure is simple and convenient for gas diversion and diversion;

[0035] 2. The adjacent packing bodies 1 are installed and used by using the mounting screws 8 and the positioning nuts 4. By controlling the mounting positions of the adjacent packing bodies 1 on the surfaces of the mounting screws 8 and the vertical spacing between the adjacent packing bodies 1, the installation and spacing adjustment of the packing bodies 1 can be quickly realized, which is convenient for multi-stage control and adjustment when used in the tower. The structure is simple and easy to install.
