DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 The utility model provides a technical solution: an explosion-proof closed internal combustion engine valve assembly, including a valve body 1, a connecting tube 2, a fixing ring 3, a connecting pipe 4, a sealing ring 5, a fixing clamp 6, a fastening bolt 7, a fixing column 8, a connecting mechanism 9, a connecting plate 10, a connecting bolt 11, a mounting plate 12, a connecting rod 13, a filter screen 14, a protrusion 15, a connecting column 16 and a movable rod 17.

[0028] When using the explosion-proof closed internal combustion engine valve assembly, Figure 1 , Figure 2 and Figure 3As shown, the left side of the gas valve body 1 is integrally connected with a connecting tube 2, and the left side of the connecting tube 2 is fixedly connected with a fixing ring 3, and the connecting pipe 4 is connected to the internal combustion engine, which is not shown in the figure. When the gas valve body 1 and the connecting pipe 4 are docked and installed, the fixing clamps 6 are first clamped at the upper and lower ends of the connecting pipe 4 respectively, and then the fixing clamps 6 at the upper and lower ends are fixed by fastening bolts 7, and then the fixing ring 3 is driven by the connecting tube 2 to be inserted into the connecting pipe 4, and a sealing ring 5 is provided between the connecting tube 2 and the connecting pipe 4. The sealing effect of the connection is improved by the setting of the sealing ring 5;

[0029] Combined with the setting of the connecting mechanism 9, as Figure 4 As shown, the connecting mechanism 9 includes a connecting plate 10 fixedly connected to the outside of the connecting tube 2, a connecting bolt 11 for adjustment, a mounting plate 12 with a limiting function, and a connecting rod 13 fixedly connected to the front and rear sides of the mounting plate 12. The mounting plate 12 is aligned with the fixing column 8. By rotating the connecting bolt 11 threadedly connected to the connecting plate 10, the connecting bolt 11 and the mounting plate 12 are rotated, thereby driving the mounting plate 12 to extend and retract in the middle of the connecting plate 10. At this time, the mounting plate 12 drives the connecting rod 13 to slide between the connecting plate 10, so that the movement of the mounting plate 12 is more stable, the mounting plate 12 is engaged with the fixing column 8, and the inner side wall of the mounting plate 12 fits with the side of the fixing column 8, which can play a certain squeezing effect on the fixing column 8, thereby improving the tightness of the connection between the connecting tube 2 and the connecting pipe 4.

[0030] Through the above operation, the gas valve body 1 and the connecting pipe 4 can be easily installed, docked and disassembled. Figure 1 and Figure 4 As shown, a filter screen 14 is fitted inside the connecting tube 2. The filter screen 14 can filter the discharged substances to prevent the air valve body 1 from being blocked, and can effectively prevent burst closure. When the filter screen 14 needs to be disassembled and cleaned, first, the connection between the connecting tube 2 and the connecting pipe 4 is loosened through the connecting mechanism 9, and the finger is inserted into the fixing ring 3 and the connecting tube 2 to slowly move the movable rod 17. The movable rod 17 and the connecting column 16 are rotated, and the movable rod 17 and the fixed bracket 18 are threadedly connected. The movable rod 17 drives the connecting column 16 to extend and retract, so that the connecting column 16 is disengaged from the protrusion 15, and then the limit of the filter screen 14 is loosened, so that the filter screen 14 can be disassembled and cleaned, which is very convenient to use.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
